Description

DESCRIPTION

Connection component

The invention relates to a connection component for connecting different scaffolding systems, which comprises at least a first connection zone intended for connection to a first scaffolding system and having an axis extending along a longitudinal axis, and a fastening zone intended for connection to a second scaffolding system, the first connection zone and the fastening zone being arranged side by side in the direction of the longitudinal axis and the first connection zone having at least on its side remote from the fastening zone in its interior a receptacle in the axis extending in the direction of the longitudinal axis. The fastening zone has a stop adjacent to the first connection zone, which extends in a direction substantially perpendicular to the longitudinal axis, and the stop has the longest dimension of the fastening zone in the direction substantially perpendicular to the longitudinal axis. The fastening zone furthermore has an insertion zone extending in the direction of the longitudinal axis and which adjoins the stop in the direction of the longitudinal axis on the side of the stop opposite the first connection zone. The invention further relates to a scaffold section for connecting different scaffold systems to a connecting component.

Scaffolding is used in the construction industry for a variety of tasks. Facade scaffolding is used to design the exterior surfaces of buildings, for example to paint them. Facade scaffolding is usually constructed from facade scaffolding frames as main components; more recently, these are also constructed from modular scaffolding. In civil engineering, shoring scaffolding is used to position and hold in place the most diverse construction elements. Such construction elements can be, for example, prefabricated concrete elements, steel beams or steel structures. In addition, elements required for the construction of structures such as temporary structures or formwork can be placed with shoring scaffolding. Finally, scaffolding is also used in the service or inspection area, for example to bring workers safely to system parts that need to be checked in large process engineering plants such as refineries. In general, the basic requirements for scaffolding are that it is easy to transport and easy to assemble.

There are different scaffolding systems for different applications. These scaffolding systems are built as a modular system and facilitate the assembly of individual scaffolding forms from standardized components. However, these components can usually only be efficiently combined with components of the same scaffolding system and can only be connected with great effort to another scaffolding system. For example, as an auxiliary measure in bridge construction, there are scaffolding systems from civil engineering that are very sturdy and are designed to temporarily support bridge components during their construction. In order for workers to be able to work on a bridge under construction, the auxiliary construction measures of the bridge must also have steps, railings, stairs and the like. However, these elements are usually created using a different scaffolding system, such as facade scaffolding. In the example of bridge construction, the construction aid or supporting structure of the bridge, which is formed by a first scaffolding system, must be connected to work surfaces for workers, which are formed by a second scaffolding system. In this case, interfaces must be provided that allow the connection of a second scaffolding system to a first scaffolding system. In the state of the art, this is often achieved by means of individually adapted connecting components, which are created on site. The disadvantage of these self-produced connecting parts is that their load-bearing capacity is often not properly assessed and their creation is labor-intensive. Another problem with these individually constructed connecting parts is that the grid, which represents a basic dimension of a scaffolding system, often cannot be maintained when assembling such connecting parts. If a connecting part does not fit into the grid of a scaffolding system, the other parts of the modular system of the scaffolding system often cannot be connected to it as planned and additional adjustment work is required during the assembly of the scaffolding.

International patent application WO2019/161825A1 describes a post connection adapter with which a vertical post of a first scaffolding system can be connected to a support of another scaffolding system. The proposed adapter can be connected via several connection components to the support, which has several connection openings. The disadvantage of the proposed solution is that such an adapter can only be connected to supports with a precisely defined width. Furthermore, the adapter only allows the one-sided connection of a second scaffolding system to a first scaffolding system. If a bilateral connection is required, several adapters are needed, which leads to a higher workload and in most cases the adapter cannot maintain the grid dimensions of a scaffolding system.

Document CN108316634A describes a lashing device intended for fixing scaffolding elements to two supports oriented parallel to each other. The device consists of two horizontally oriented plates, which are snap-connected to the supports via vertically oriented connecting components.

Document JPS6062365A describes a device intended to suspend a scaffold section on two horizontally aligned and parallel supports. Part of this device passes between the parallel oriented supports.

The aim of the invention is therefore to propose solutions with which scaffolding elements of at least two different scaffolding systems can be securely connected to each other, this connection being intended to enable the extension of at least two different scaffolding systems via the connection point with a reduced adjustment effort.

This objective is solved by a connection component according to claim 1.

A connection component according to the invention is used to connect two different scaffolding systems. For this purpose, the connection component each has an interface for connection to a first scaffolding system and an interface for connection to a second scaffolding system. These interfaces enable a quick, simple and secure connection of the connection component to both scaffolding systems. The connection component comprises at least a first connection region, which forms the interface to a first scaffolding system. The connection region has an axis extending along a longitudinal axis. In most cases, this longitudinal axis corresponds to a construction direction of the first scaffolding system. Preferably, the longitudinal axis is arranged symmetrically with respect to the axis. This longitudinal axis serves as a geometric basis for describing further elements and the relationships between these elements. Preferably, the axis is cylindrical. However, other cross-sectional shapes of the axis are also feasible, for example a square cross-section. As an interface to a second scaffolding system, the connection component has a fastening region. The first connection zone and the fixing zone are arranged adjacent to each other in the direction of the longitudinal axis. Thus, the interfaces of the connection component with the first scaffold with the first and second scaffold systems are arranged directly adjacent to each other. The first connection zone has a receptacle within its axis at the end facing away from the fixing zone. This receptacle extends along the longitudinal axis. The receptacle is provided such that when the connection component is connected to an element of a first scaffold system, at least a part of this element can be inserted into the receptacle. In this way, a positive connection is created between the connection component and the first scaffold system, which allows a simple and safe assembly of the connection component and the first scaffold system. The receptacle preferably has a circular cross section and extends linearly along the longitudinal axis. The interior of the receptacle is therefore preferably cylindrical. The shape and size of the housing correspond to the shape and size of the housings used in the first scaffolding system for connecting several scaffolding elements of the same modular system to one another. In this way, different elements of the first scaffolding system can be easily connected to the housing of the first connection zone of the connecting component. The housing can extend along the longitudinal axis over the entire axis or only over a part of the axis. The fixing zone comprises a stop which is arranged directly next to the first connection zone. This stop extends in a direction essentially perpendicular to the longitudinal axis and is provided as a stop for the connecting component in an element of a second scaffolding system. The stop serves at the same time as a positioning aid and for transmitting force and torque between the connecting component and the second scaffolding system. By extension of the stop perpendicular to the longitudinal axis is meant that the longest dimension of the stop, its length, is aligned perpendicular to the longitudinal axis. The thickness of the stop is preferably oriented parallel to the longitudinal axis. A width of the stop runs at right angles to the longitudinal axis and the length of the stop. Advantageously, the stop is plate-shaped. The longest dimension of the fastening area in the radial direction to the longitudinal axis is located at the stop. In other directions, for example parallel to the longitudinal axis, other elements of the fastening area can have longer dimensions than the largest dimensions of the stop. The axis of the first connection area and the stop merge sharply into one another, i.e. the outer surface of the axis is oriented at right angles to the surface of the stop facing the first connection area. The stop, viewed from above in the direction of the longitudinal axis, preferably has a rectangular shape, the length of the stop being greater than its width. The stop has the longest dimension of the fastening area by its length. This means that the stop projects beyond other parts of the fastening area. Another such sub-area of the fastening area is the insertion area, which extends next to the stop on the side of the stop facing away from the first connection area. The insertion zone is intended to be inserted into one or between two elements of the second scaffolding system. The insertion zone comprises at least one first insertion interface, which is designed such that it can at least partially form a positive connection with the second scaffolding system. The first insertion interface has two first stop surfaces, which are arranged parallel to one another and/or symmetrically to the longitudinal axis. The stop surfaces can be flat or curved. The two first stop surfaces form outer surfaces of the insertion zone and are arranged on its outer circumference. The first stop surfaces are arranged at a distance from the longitudinal axis in a radial direction to the longitudinal axis. The longest extension of the stop surfaces runs parallel to the longitudinal axis. This means that the longest extension or dimension of the two stop surfaces is oriented parallel to the longitudinal axis. The two first stop surfaces can be fixedly arranged in the fixing zone. Alternatively, the position of the two first stop surfaces relative to the longitudinal axis can also be designed to be adjustable. The distance between the two first stop surfaces can then also be adjusted and can therefore be easily adapted to different second scaffolding systems. For a positive connection of the fastening area to the second scaffolding system, the insertion area also has a safety recess that runs through the entire insertion area and is arranged essentially at right angles to the two first stop surfaces. When connecting the connecting component to the second scaffolding system, a plug-in element or an insert element can be inserted into the safety recess, which is also inserted into a receiving recess in the second scaffolding system. In this way, a positive connection between the connecting component and the second scaffolding system can be established by means of pins. This type of pinning between two components to be connected to one another is also used in many scaffolding systems between elements of the same modular system. Such a connection is easy to establish and stable.

The stop of the connection component according to the invention can project further beyond the adjacently arranged insertion area in a first direction radial to the longitudinal axis than in a second direction, which also runs radially to the longitudinal axis and at the same time substantially perpendicular to the first direction. This means that in one partial area the stop can project further beyond the longitudinal axis in the circumferential direction than in another partial area. The projection of the stop on the longitudinal axis can therefore have an unequal size in the circumferential direction around the longitudinal axis. Preferably, the stop projects more from the longitudinal axis in a first radial direction towards the longitudinal axis, which corresponds to the radial direction towards the longitudinal axis aligned perpendicular to the two first stop surfaces. In this way, it can be ensured that the stop rests securely on a scaffold element of the second scaffold system, if the first insertion interface with the two first stop surfaces are arranged within this scaffold element of the second scaffold system. Furthermore, this uneven protrusion of the stop on the longitudinal axis can ensure that in partial areas outside the first surfaces of the stop, the stop protrudes less from the insertion interface, where it is normally not necessary to position the stop on a scaffold element of the second scaffold system. This configuration of the stop ensures that the connecting component has an optimally low weight.

Furthermore, the stop protrudes beyond the longitudinal axis in a first direction radial to the longitudinal axis, which has the longest dimension of the fastening area radially to the longitudinal axis, than in a second direction radial to the longitudinal axis and substantially perpendicular to the first direction. Therefore, the stop does not protrude the same distance in the circumferential direction in a plan view from the direction of the longitudinal axis. This configuration ensures that the connecting component has a shape that is optimally integrated into the second scaffolding system and does not protrude from its scaffolding elements in a direction radial to the longitudinal axis.

The connection component according to the invention has the advantage that it can be connected very easily and without the need for individual adjustments to two different scaffolding systems. A first scaffolding system can be connected simply by means of a plug connection to the housing in the first connection area. This connection via the housing essentially corresponds to other connections that are used between different scaffolding elements of the first scaffolding system. The first connection area is therefore integrated into the first scaffolding system and is fully compatible with other scaffolding elements of the modular system of the first scaffolding system. The same applies to the plug-in interface and the second scaffolding system: the shape and dimensions of the plug-in interface correspond to an interface that is essentially also used between scaffolding elements of the second scaffolding system. In this way, the plug-in interface or the fastening area can be directly integrated into a second scaffolding system without the need for adjustment. The inventive arrangement of the first connection zone and the fastening zone thus works in many cases where two scaffolding systems are to be connected to one another. The inventive connection component can therefore be used as a standard connection between the two scaffolding systems. The connection to the second scaffolding system can also be easily implemented and secured by means of a plug-in connection, with the provision of the safety recess. This enables a fast and safe construction of a scaffolding section comprising scaffolding elements of the first scaffolding system and the second scaffolding system. By using the inventive connection component when joining two scaffolding systems, assembly time for the respective scaffolding section can be saved. Another advantage of a connection component according to the invention is that the first connection zone and the fastening zone can be dimensioned so that they correspond to the grid of the first scaffolding system and the second scaffolding system. In this way, both the first scaffolding system and the second scaffolding system can be further extended on the respective grid used by this scaffolding system. This means that the performance of both scaffolding systems can be fully maintained at the entire connection point. Thanks to its simple structure, the connection component according to the invention is robust and at the same time has a low weight. This means that it can be easily transported and fixed to a scaffolding section.

In one embodiment, it is provided that the connection component also has a second connection zone, which is intended for connection to a first scaffolding system and that the second connection zone is arranged in the direction of the longitudinal axis on the side of the stop opposite the first connection zone, the second connection zone having a receptacle extending along the longitudinal axis, the inner cross section of the receptacle oriented perpendicular to the longitudinal axis having a shape that is substantially identical to the shape of the inner cross section of the receptacle of the first connection zone in a plane perpendicular to the longitudinal axis. In this embodiment, the connection component comprises two connection zones, which are provided as interfaces for connection to the first scaffolding system. The second connection zone is arranged in the direction of the longitudinal axis opposite the first connection zone. The second connection zone is located on the side of the stop opposite the first connection zone. The second connection zone can extend partially into the fastening zone or can be arranged adjacent to the fastening zone on the side opposite the first connection zone. The second connection zone also comprises a housing into which scaffolding elements of the first scaffolding system can be inserted. Preferably, the housing of the second connection zone is designed identically to the housing of the first connection zone. In particular, the cross-sectional area of the housing in the direction perpendicular to the longitudinal axis is identical. In this embodiment, the distance between the ends of the first connection zone and the second connection zone can be selected such that this distance corresponds to a grid dimension of the first scaffolding system.

In this way, the grid of the first scaffolding system is maintained when the connecting component is mounted between the scaffolding element of the first scaffolding system. In this embodiment, scaffolding elements of the first scaffolding system can be connected on both sides of the fastening zone. In this embodiment, a crossing between the first scaffolding system and the second scaffolding system, which is connected to the fastening zone, can thus be easily realized. The second connecting zone can include a second axis, which contains the receptacle and is designed in the same or similar manner as the axis of the first connecting zone. Such an axis can be formed, for example, by a tubular section of a cylindrical tube.

In another embodiment, it is provided that the insertion area of the fastening area also has a second insertion interface, which comprises two second stop surfaces oriented parallel to one another and/or symmetrically to the longitudinal axis, which are arranged on the outer sides of the insertion area in a radial direction to the longitudinal axis and parallel to the longitudinal axis, and the second insertion interface comprises at least one safety recess which runs through the entire insertion area and extends substantially at right angles to the two second stop surfaces, and the two second stop surfaces are oriented at an angle, in particular at right angles, to the two first stop surfaces. In this embodiment, the insertion area of the fastening area comprises two insertion interfaces of different sizes. These two different insertion interfaces make it possible to connect the connecting component to scaffolding elements of different sizes of the second scaffolding system. The first insertion interface is intended for connection to a first type of scaffold element of the second scaffold system and the second insertion interface is intended for connection to a second type of scaffold element of the second scaffold system. The two insertion interfaces are substantially identical, but differ from each other in details regarding shape and dimensions. These details are described in other embodiments. The two second stop surfaces are offset in the circumferential direction around the longitudinal axis with respect to the two first stop surfaces. Thus, the second stop surfaces are arranged at an angle to the first stop surfaces. Therefore, the normals to the second stop surfaces are also arranged at an angle to the normals to the first stop surfaces. This angle between the first stop surfaces and the second stop surfaces is preferably 90°. In this embodiment, the first insertion interface is offset at a right angle in the circumferential direction around the longitudinal axis with respect to the second insertion interface. The first insert interface serves to connect the connection zone to a scaffold element of the first type of the second scaffold system. If the connection component is to be connected to a scaffold element of the second type of the second scaffold system, then the connection component is simply rotated 90° around the longitudinal axis and the second insert interface is used for the connection to the second scaffold system. In this embodiment, it is therefore possible to establish a connection to a first type or a second type of the second scaffold system simply by rotating the connection component. No adjustment work is required when changing the connection from the first type to the second type. This embodiment of the connection component can therefore be connected directly and without additional work via the fastening zone to two different types of scaffold elements. By providing the second insert interface, the range of uses of the connection component is further increased. In addition, the second insert interface also increases the stability of the fastening zone, so that the connection component can absorb and withstand a higher load. Preferably, the two insertion interfaces are configured symmetrically with respect to the longitudinal axis, so that the connecting component remains fully integrated into the grid of the second scaffolding system and into the grid of the first scaffolding system when both insertion interfaces are used. Due to the basically identical configuration of the two insertion interfaces, the working steps when connecting the connecting component to the second scaffolding system are almost identical for both insertion interfaces, so that the working personnel can assemble and disassemble the connecting component easily and safely.

In an advantageous embodiment, it is provided that the receptacle of the second connection zone is arranged coaxially with respect to the longitudinal axis and thus aligned with the receptacle of the axis of the first connection zone, the receptacle having a front opening and the receptacle having a front opening and the front opening and the front opening being arranged on opposite sides of the connection component. In this embodiment, the two connection zones are arranged coaxially with respect to one another. The two connection zones are thus located in a common line of action for the transmission of forces. In this embodiment, the two connection zones are arranged in the same way as the connection zones are arranged with respect to one another on a vertical post of a first scaffolding system. In this way, the connection component behaves like a vertical post of the first scaffolding system and can therefore be integrated particularly easily into the first scaffolding system. Elements of the first scaffolding system can be introduced into the connection component via the front openings arranged on opposite sides of both receptacles.

It is advantageous to provide that the second connection zone is arranged within the fastening zone. In this embodiment, the second connection zone is arranged within the fastening zone or is surrounded by it. This creates a compact arrangement of the interfaces of two scaffolding systems with a short overall length of the connecting component.

Alternatively, it is provided that the second connection zone projects beyond the fixing zone in the direction of the longitudinal axis on the side of the fixing zone opposite the first connection zone. In this embodiment, the second connection zone projects beyond the fixing zone on the side of the connecting component opposite the first connection zone. A part of the second connection zone can also be arranged within the fixing zone. This projection of the second connection zone makes it possible to increase the overall length of the connecting component, for example to adapt the connecting component to a longer grid dimension of a first scaffolding system. In addition, the second connection zone is more easily accessible when it projects beyond the fixing zone.

In another preferred embodiment, it is provided that the second connection region has an axis which projects at least in regions opposite the first connection region above the fixing region, the receptacle being arranged at least in certain regions on the axis. In this embodiment, the second connection region also has an axis which is designed similarly or identically to the axis of the first connection region. The receptacle of the second connection region can be arranged wholly or partially on the axis.

It is further provided that the first connection area and/or the second connection area has at least one plug-in opening which extends radially to the longitudinal axis and which runs through the entire first connection area and/or the entire second connection area. In this embodiment, a plug-in opening which is preferably arranged on the axis is provided in one or two connection areas. A plug-in element or an insert element can be inserted into this plug-in opening in order to connect the connection component and an adjacent scaffolding element of the first scaffolding system in a positive-fitting manner. This type of pin is also used in many scaffolding systems for connecting the same or different scaffolding elements within the scaffolding system. The insertion opening in the connection area thus forms a further connection interface between the connection component and the first scaffolding system and increases the security of the connection between the elements.

Furthermore, it is advantageously provided that the receptacle of the first connection zone and/or the receptacle of the second connection zone have a circular inner cross section perpendicular to the longitudinal axis. In this embodiment, the receptacle in the first and/or second connection zone is cylindrical. This embodiment is suitable for first scaffolding systems having cylindrically dimensioned interfaces. Of course, the cross section of the receptacle can also have another shape that is suitable for the interfaces of the first scaffolding system.

It is advantageously provided that the first connection region and/or the second connection region are formed at least in some regions by a tube. In this embodiment, the connection region is formed by a section of tube. In addition to the section of tube, the connection region may have other components. This embodiment is particularly easy to produce.

Furthermore, it is provided that the stop closes the receptacle in the first connection region in the axial direction along the longitudinal axis or at least reduces its inner diameter. In this embodiment, the stop is designed such that it at least partially narrows the inner diameter. The stop projects into the interior of the support. In this way, a scaffold element of the first scaffold system inserted into the receptacle can be supported on the stop in an axial direction parallel to the longitudinal axis. In this way, forces can be transmitted from the inserted scaffold element to the connecting component. Alternatively, it is also possible for the receptacle in the first connection region and the possible receptacle in a second connection region to merge with one another without narrowing in their interior. In this alternative case, the stop does not project into the interior of the receptacle. This makes it possible to pass elements completely through the receptacle and through the entire connecting part along the longitudinal axis. In this case, the forces can be supported and transmitted via the end of the connection region remote from the stop. As described above, it is also possible to provide a first connection zone and a second connection zone, both of which are formed together by a common continuous pipe section which is not narrowed in its interior by the stop. In this case, the stop is designed so that it is located completely outside the pipe section and is firmly connected to it on its outer surface.

Advantageously, it is provided that the first connection region has a connection disk which is fixed to an outer surface of the shaft, the connection disk extending in a radial direction relative to the longitudinal axis and the connection disk having at least one flat connection surface which is oriented substantially at right angles to the longitudinal axis and at least one connection recess being arranged on the connection surface which extends completely into the connection disk parallel to the longitudinal axis. In this embodiment, a connection disk is arranged on the outer side of the shaft, which serves to connect the first and/or second connection region to scaffolding elements of the first scaffolding system. The connection disk extends radially away from the longitudinal axis. In a plan view in the direction of the longitudinal axis, the connection disk can have a round, square, rosette-shaped or other external shape. The connection disk has a flat connection surface oriented perpendicular to the longitudinal axis. Preferably, a plurality of connection recesses are arranged on the connecting surface, through which interfaces of scaffolding elements of the first scaffolding system can be guided. These connection discs are also used on other scaffolding elements of the first scaffolding system, for example on vertical posts. The shape of the connection recess(es) can be adapted to the interfaces of the respective first scaffolding system.

It is advantageously provided that the stop of the fixing zone projects beyond the first connection zone in a radial direction to the longitudinal axis. In this embodiment, the stop projects beyond the connection zone, at least at the point where the stop is connected to the first fixing zone. This results in a sudden transition between the connection zone and the fixing zone to which the stop belongs. However, this transition can also have a chamfer or a radius, which makes the transition between the connection zone and the fixing zone less abrupt and thus reduces the occurrence of recess effects. If the connection zone has a connection disk, this can also extend beyond the stop in a radial direction towards the longitudinal axis.

In an advantageous embodiment, it is provided that the outer diameter of the insertion zone in the radial direction of the longitudinal axis is larger than the inner diameter of the receptacle of the first connection zone and/or is larger than the inner diameter of the receptacle of the second connection zone. In this embodiment, the outer peripheral surface of the insertion zone projects radially further beyond the longitudinal axis than the inner diameter of the receptacle. The insertion zone is intended to be inserted into one or between two scaffold elements of the second scaffold system. Since the inner diameter of the receptacle intended to receive a scaffold element of the first scaffold system is smaller than the outer diameter of the insertion zone, scaffold elements of the first scaffold system can be guided through the connection component and thus through transverse scaffold elements of the second scaffold system. This embodiment is particularly advantageous because the two scaffold systems can be connected to one another continuously in their grid by means of the connection component. In this way, the crossing of the two scaffolding systems can be carried out in essentially the same way and is just as stable as if the individual grid of each scaffolding system were extended.

It is advantageously provided that the stop is made up of several components and in some regions is made up of a cover plate oriented substantially at right angles to the longitudinal axis and in some regions of a partial surface of at least one insert plate oriented parallel to the longitudinal axis, the insert plate also providing at least part of the first stop surfaces. In this embodiment, the stop is made up of several partial regions, which are formed by different but interconnected components of the fastening area. The stop comprises a cover plate which projects in a radial direction relative to the longitudinal axis over the first connection area connected to it. At least one insert plate is arranged immediately adjacent to the cover plate and connected to it, a part of which belongs to the stop. Another part of the insert plate belongs to the insertion area and provides at least one of the first stop surfaces. The part of the insert plate belonging to the insertion zone is inserted into a scaffold element or between two scaffold elements of this second scaffold system when it is connected to the second scaffold system. The area of the insert plate belonging to the stop is not inserted into the second scaffold system, but can serve as a support surface when positioning the connection component with the second scaffold system.

Advantageously, it is provided that the stop has a first flat contact surface which is oriented substantially at right angles to the longitudinal axis and which projects radially from the first two contact surfaces to the longitudinal axis. In this embodiment, the stop has a first contact surface which is arranged on the side opposite the first connection region. The contact surface is oriented at right angles to the longitudinal axis and projects radially from the first two contact surfaces. The first contact surface is intended to rest on a scaffold element of the second scaffold system if the two first contact surfaces are inserted into one or between two scaffold elements of the second scaffold system. In this case, the two first contact surfaces rest within the second scaffold system and the first contact surface defines the assembly position or connection position between the second scaffold system and the connection component.

In an advantageous embodiment, it is provided that the first support surface is arranged on the cover plate or at least on an insert plate. The first support surface can be arranged either on the side of the cover plate remote from the first connection area or on a surface of an insert plate remote from the first connection area. If several insert plates are provided, in particular arranged parallel to one another, the first support surface can also be composed of surfaces of several insert plates.

It is further provided that the first support surface and the first two stop surfaces are arranged adjacent to each other and/or directly next to each other. In this embodiment, the first support surface and the first two stop surfaces are arranged directly next to each other. In particular, these two surfaces are arranged at right angles to each other. This directly adjacent arrangement enables a particularly stable connection to a scaffold element of the second scaffold system. This scaffold element of the second scaffold system typically has two surfaces that are also adjacent to each other and arranged at right angles to each other. The described configuration of the first support surface and the first stop surfaces thus enables an optimal positive connection between the fastening area and the scaffold element of the second scaffold system.

In one embodiment, it is provided that two insert plates are provided which are aligned parallel to one another and arranged symmetrically with respect to the longitudinal axis. In this embodiment, the fastening area comprises two insert plates. These two insert plates are arranged symmetrically with respect to the longitudinal axis. If a part of a second connection area runs inside the fastening area, then the two insert plates can be connected or fixed to it. Preferably, the two insert plates are identical to one another in shape and dimensions.

In another embodiment, it is provided that the insert plate has a fixing surface which is oriented substantially at right angles to a normal to the longitudinal axis and has an edge region which is oriented at right angles to the fixing surface and surrounds the insert plate and that partial regions of the two first stop surfaces are arranged in mutually opposite partial regions of the edge region. In this embodiment, the insert plate comprises a fixing surface which is flat or curved. This fixing surface is oriented at right angles to the direction normal to the longitudinal axis. The fixing surface is arranged on the side of the insert plate which faces inward in the direction of the longitudinal axis. The fixing surface is preferably flat. In addition to the fixing surface, an edge region surrounds the insert plate. This edge region is preferably formed by surfaces oriented at right angles to the fixing surface. Parts of this edge region form part of the first stop surfaces. Part of a first stop surface is formed by a first partial region of the edge zone. A part of a second first stop surface is formed by the second partial region of the edge zone, which is opposite the first partial region of the edge zone.

It is advantageously provided that the first support surface is arranged in the edge region adjacent to a partial region of the two first stop surfaces. In this embodiment, both the first support surface and a partial region of the two first stop surfaces are arranged in the edge region of the insert plate. The first stop surfaces and the first support surface are adjacent and preferably arranged at right angles to one another.

In one embodiment, it is provided that two insert plates are provided and parts of the edge regions of both insert plates together form the first support surface and the two first stop surfaces. In this embodiment, two insert plates are provided, arranged symmetrically with respect to the longitudinal axis, which together form both the first support surface and the two first stop surfaces. This embodiment is particularly stable. The partial regions of the two first stop surfaces are arranged at a distance from each other, which favors the transmission of force and torque between the connecting component and the second scaffolding system. In addition, the provision of two insert plates simplifies the arrangement of a second insert interface with second stop surfaces. A further embodiment will be described below.

Furthermore, it is advantageously provided that the safety recess is arranged in a sub-region of the fastening zone other than the insert plate. In this embodiment, the safety recess does not extend through an insert plate. The safety recess can, for example, extend in a sub-region of the third connection zone, which is arranged within the fastening zone. The safety recess can also be arranged in another component of the fastening zone. If two insert plates are provided, the safety recess is preferably provided between the two insert plates and crosses the longitudinal axis.

It is conveniently provided that a plurality of safety recesses are provided in the direction of the longitudinal axis at a distance from one another. In this embodiment, a plurality of safety recesses are provided in the direction of the longitudinal axis, with which the connecting component can be fastened simultaneously or selectively to one or more scaffold elements of the second scaffold system. By providing a plurality of safety recesses, the connecting component can be connected to scaffold elements of different sizes of the second scaffold system without any adjustment work being necessary. If a plurality of safety recesses are used for fastening at the same time, the load-bearing capacity of the connection can be increased.

Furthermore, it is advantageously provided that the insertion region of the fastening region has a second insertion interface, the second abutment surfaces of which are arranged in each case on an insertion plate, the abutment surfaces being formed by outer surfaces oriented parallel to a corresponding fastening surface. In this embodiment, the fastening region has two insertion interfaces, which can optionally be connected to a scaffold element of a second scaffolding system. Each of these two insertion interfaces has two abutment surfaces. The two second abutment surfaces of the second insertion interface are each arranged on one of the two insertion plates. Each of the abutment surfaces is formed by surfaces representing outer surfaces of the respective insertion plate. These outer surfaces are arranged parallel to the respective fastening surface of each insertion plate. In this embodiment, the edge regions of the two insert plates together form the two first stop surfaces and an outer surface of each insert plate alone forms one of the two second stop surfaces. In this embodiment, all stop surfaces of the two insert interfaces are arranged in an appropriate manner on the two insert plates. A connection component configured in this way is therefore made up of only a few components and is therefore simple in structure, compact and has a low weight. However, this embodiment has two different insert interfaces, which can be flexibly connected to scaffolding elements of different sizes of a second scaffolding system.

It is advantageously provided that the stop has a second flat support surface which is oriented substantially at right angles to the longitudinal axis and which projects in a radial direction relative to the longitudinal axis over the two second stop surfaces. In this embodiment, the second insertion interface is assigned a second separate support surface on the stop. In order to act as a stop in the connection between the connecting component and one or more scaffold elements of a second scaffold system, the second support surface projects radially towards the longitudinal axis beyond the second stop surfaces. The second support surface can also be formed by two partial surfaces which are arranged spaced apart from one another and adjacent to one of the two stop surfaces. The second support surface and the two second stop surfaces are preferably oriented at right angles to one another. The first support surface and the second support surface can be arranged in the same plane or in different planes arranged parallel to one another.

In an advantageous embodiment, it is provided that the second support surface is formed by one surface of the cover plate and that the second support surface adjoins the two second stop surfaces. In this embodiment, the second support surface is a partial surface of the cover plate, which is arranged on the side of the cover plate facing away from the connection region. The second support surface can be divided into two and formed by two separate partial surfaces of the cover plate. The second support surface directly adjoins the two second stop surfaces. The second support surface is preferably oriented at right angles to the second stop surfaces. The second support surface can protrude beyond the two second stop surfaces to the same extent as the first support surface protrudes beyond the two first stop surfaces. Alternatively, the projection of the second support surface over the second stop surfaces can also be designed to be different from the projection of the first support surface over the first stop surfaces.

It is advantageously provided that the safety recess extends through at least one insertion plate. The second insertion interface further comprises a safety recess extending through the entire insertion area. A plug-in element can be inserted into this safety recess for securing and fixing the connection component to a scaffold element of the second scaffolding system. The safety recess of the second insertion interface is designed in a manner analogous to the safety recess of the first insertion interface. The safety recess extends from at least one second stop surface in a radial direction through the insertion area. The safety recess extends through at least one insertion plate. In an embodiment in which two insertion plates are provided, the safety recess preferably extends through both insertion plates.

Advantageously, it is provided that a plurality of safety recesses are provided at a distance from one another in the direction of the longitudinal axis. In this embodiment, a plurality of safety recesses are also provided on or within the second insertion interface. In this way, the connecting component can also be connected via the second insertion interface to scaffolding elements of another configuration of the second scaffolding system without any adjustment work being necessary.

It is further provided that the distance between the two first stop surfaces differs from the distance between the two second stop surfaces. The distance between the two first stop surfaces preferably differs from the distance between the two second stop surfaces. The dimensions of the two insertion interfaces therefore differ from one another, with the connection component being able to be connected via the two insertion interfaces to scaffolding elements of different sizes of the second scaffolding system. Depending on which scaffolding element of the second scaffolding system the connection component is to be connected to, the first insertion interface or the second insertion interface is used for this connection.

The object of the invention is further solved by a scaffold section for connecting different scaffold systems, which comprises at least one connection component according to one of the embodiments described above, at least one scaffold element of a first scaffold system which is positively connected to the first connection zone and/or the second connection zone of the connection component, and at least one scaffold element of a second scaffold system which is positively connected to the fastening zone of the connection component, the first scaffold system and the second scaffold system being different from each other. A scaffold section according to the invention comprises at least one connection component. This connection component is connected in the scaffold section to a first scaffold system and a second scaffold system. The first scaffold system is positively connected to the first connection zone of the connection component, for example by a plug-in connection. If the connection component has a second connection zone, another scaffold element of the first scaffold system can additionally be connected to the second connection zone. The positive connection between the first scaffold system and the connection zone can be additionally reinforced and secured by inserting a plug-in element. The plug-in element then creates a further positive connection between the connection component and the first scaffold system. The scaffold section according to the invention further comprises at least one scaffold element of a second scaffold system, which is connected in a positive-locking manner to the fastening zone of the connection component. This connection can also be reinforced and secured by pins using the safety gap. The first and second scaffold systems differ from one another and have different connection interfaces. In the scaffold section according to the invention, the connection component acts as an adapter between the two different scaffold systems. Since the connection component has both an interface for connection to the first scaffolding system and an interface for connection to the second scaffolding system, a connection between both scaffolding systems is possible in a simple manner and without adjustment effort. A scaffolding section according to the invention can thus be assembled and disassembled quickly and easily. The connection component is dimensioned such that when connecting two different scaffolding systems, the grids of both scaffolding systems are maintained along the connection point. In this way, the scaffolding section is integrated into both scaffolding systems and the advantages of both scaffolding systems are maintained despite the connection point.

In one embodiment, it is provided that the scaffold element of the first scaffold system is formed by a vertical post of a frame or scaffold system and the scaffold element of the second scaffold system is formed by a horizontal beam, the horizontal beam comprising two support rails that are spaced apart from each other and aligned parallel to each other. In this embodiment of the scaffold section, the scaffold element of the first scaffold system connected to the connection zone is a vertical post. These vertical posts are used in frame scaffold systems or system scaffolds. Such a vertical post is usually aligned vertically in a scaffold section. The scaffold element of the second scaffold system is formed in this embodiment by a horizontal beam that is usually oriented horizontally. This horizontal beam is intended to support high loads and is part of a scaffold system that is preferably used in civil engineering. Such a horizontal beam can be intended, for example, to support and position prefabricated construction parts. The horizontal beam comprises two support rails that are separated from each other and run parallel to each other. The two support rails are connected to each other at several points and thus form the horizontal beam. The two support rails usually have an I-, C- or T-shaped cross section, which is particularly favourable for achieving high bending resistance.

It is conveniently provided that the vertical post is inserted into the housing of the first connection zone or into the housing of the second connection zone. The vertical post of the first scaffolding system is inserted into the housing of a connection zone in the scaffolding section. The housing may at least partially correspond to the negative shape of one end of a vertical post. Alternatively, the vertical post may be inserted into the housing with the interposition of an adapter piece.

In another embodiment, it is provided that an adapter piece is arranged between the vertical post and the receptacle of the first connection zone or the receptacle of the second connection zone, which connects the vertical post and the connection component to one another. In this embodiment, an adapter piece is arranged between the vertical post and the receptacle. This adapter piece is inserted into the receptacle of the connection component on the one hand and into a front end of a vertical post on the other hand. Such an adapter piece makes it possible to connect a connection component and a vertical post, both of which have a hollow recess as an interface, to one another. A force transmission between the vertical post and the connection component can be effected via the adapter piece. Alternatively, the force transmission can also be effected directly between the connection zone of the connection component and the front end of the vertical post. The adapter piece has in some areas a negative shape of the recess of the connection zone and in some areas a negative shape of the inside of the front end of the vertical post. The adapter piece can be provided in different lengths, which provides an additional possibility of easily adapting the lattice dimension of the connecting component to the first scaffolding system.

It is also expediently provided that the insertion area of the connecting component is arranged between the support rails of the horizontal beam and the two first stop surfaces or that the two second stop surfaces of the insertion area rest on inner surfaces of the support rails. In this embodiment of the scaffolding section, the insertion area is at least partially inserted between the support rails of the horizontal beam. The stop rests on the support rails. The distance between the stop surfaces essentially corresponds to the distance between the two support rails of the horizontal beam. In this way, a positive connection is created between the insertion area and the horizontal beam. The two stop surfaces of the first insertion interface or the second insertion interface rest on inner surfaces of the support rails facing each other. Of course, a small clearance can be provided between the stop surfaces and the inner surfaces of the support rails, through which the insertion area can be inserted between the two support rails. The arrangement of the fastening area of the connecting component between the two support rails enables a particularly stable and secure connection between the connecting component and the second scaffolding system. The connection is located within the horizontal beam and therefore does not prevent the fastening of other elements or components on the outside of the horizontal beam. In addition, this connection within the horizontal beam reduces the risk of injury to persons working on the scaffolding section due to components protruding from the scaffolding.

Furthermore, it is provided that the support rail has a receiving recess which projects perpendicularly into the support rail to its longitudinal direction, the connecting component being oriented towards the horizontal beam such that the safety recess is aligned with the receiving recesses in the support rails. In this embodiment, each of the two support rails of the horizontal beam has at least one receiving recess. This receiving recess extends completely into the support rail and has a shape and size that substantially correspond to the shape and size of the safety recess of the connecting component. When the connecting component is connected to the horizontal beam, the fastening area is inserted between the two support rails so that the safety recess and the receiving recess are aligned. Preferably, several receiving recesses are arranged in each support rail. For example, several receiving recesses can be arranged at a distance from each other in the longitudinal direction. This makes it possible to connect the connecting component to the horizontal beam at different points.

It is also advantageous to provide a plug-in element which is detachably inserted into the safety recess and the receiving recesses in a form-fitting manner and which connects the horizontal beam and the connecting component in a form-fitting manner. In this embodiment of a scaffold section, an insertion element is provided for fastening the connecting component and the horizontal beam to one another. This insertion element can be at least partially cylindrical and is always dimensioned such that it can be inserted into the safety recess and the receiving recesses. To secure the connecting component, it is inserted between the support rails such that the safety recess and the receiving recesses are aligned with one another. The insertion element is then inserted into the recesses aligned with one another. This insertion is carried out from outside the horizontal beam and is therefore easy to carry out. In addition, it is clearly visible from outside the horizontal beam whether an insertion element has been inserted or not. This is advantageous for checking the correct construction of the scaffold section before people enter the scaffold.

It is advantageously provided that the insert element has a clamping device and that the clamping device generates a force for an additional snap connection between the horizontal beam and the connecting component. In this embodiment, a clamping device is provided on the insert element, by means of which an outer dimension of the insert element can be changed in its radial direction. This clamping device is used to secure the insert element when it is inserted. The insert element is inserted into the connection between the horizontal beam and the connecting component and the clamping device is then actuated. This increases the outer diameter of the insert element in certain areas, so that it is pressed against the inner wall of the recesses. This creates a snap connection between the components and prevents the insert element from falling out. Alternatively, the insert element can also have a clamping device acting in its axial direction, formed for example by a simple external thread onto which a nut is screwed when it is inserted. In addition, instead of a clamping device, it is possible to provide a locking pin, which in the inserted state protrudes into the insert element and then protrudes beyond the insert element. In this way, the insert element cannot accidentally fall out of the recesses.

Advantageously, it is also provided that at least two spacers are inserted between the support rails, which position the two support rails relative to one another. In this embodiment, the two support rails of the horizontal beam are connected by at least two spacers. The distance between the first stop surfaces or the second stop surfaces of the connecting component is chosen to be slightly smaller than the internal distance between the two support rails fixed by the spacers.

Furthermore, it is advantageously provided that the total length of the connecting component corresponds to a grid dimension of the first scaffolding system and/or that the distance between the two first parallel stop surfaces and/or the two second parallel stop surfaces corresponds to a grid dimension of the second scaffolding system. The total length of the connecting component along the longitudinal axis is adjusted such that this length corresponds to a grid dimension of the first scaffolding system. Furthermore, the distance between the stop surfaces is coordinated with the distance between the two support rails, so that the distance between the stop surfaces corresponds to a grid dimension of the second scaffolding system.

Features, effects and advantages that are described in relation to the connecting component are also considered to be described in relation to the scaffold section. The same applies in the opposite sense; features, effects and advantages that are disclosed in relation to the scaffold section are also considered to be described in relation to the connecting component.

Figure 1 shows a schematic perspective view of a scaffold section 100 with two different scaffold systems 2 and 3. The scaffold section 100 shown here comprises a first scaffold system 1 extending in a vertical direction and a second scaffold system 3 represented by two horizontally extending beams 31. The first scaffold system 2 is a frame or system scaffold. It can be clearly seen that the first scaffold system 2 has regularly arranged and repeated scaffold elements. The first scaffold system 2 is constructed as a modular system from which different scaffold components or elements can be combined to form scaffold sections of different shapes. The first scaffold system 2 has several grid dimensions that are repeated in the scaffold section. The frame is also said to be constructed in a grid shape. Such a grid dimension extends, for example, between the horizontally extending crossbeams in the illustration, of which six are arranged on the left side of the scaffold section 100. The first scaffold system 2 has further grid dimensions, for example the length and width of the scaffold section 100 shown. In the vertical direction, a plurality of vertical posts 21 are arranged in the scaffold section 100 shown. The two horizontal beams 31 belong to a second scaffold system 3. These horizontal beams of the second scaffold system 3 support significantly higher loads than the elements of the first scaffold system 2. The second scaffold system 3 is typically used to support higher loads or to span greater distances. In the scaffold section 100 shown, the first scaffold systems 2 and the second scaffold systems 3 are connected to one another by a total of four connecting components 1. The connecting components 1 form crossing points between the two scaffolding systems 2 and 3. As can be clearly seen from the representation in Figure 1, the connecting components 1 are integrated into the grid of both scaffolding systems 2 and 3. This means that both scaffolding systems 2 and 3 can additionally be built in their own grid via the connection point formed by the connecting component 1. In this way, the modular principle of both scaffolding systems 2 and 3 is maintained, which is very advantageous for rapid assembly and disassembly as well as for ensuring the load-bearing capacity of the scaffold section 100. Details of the connecting component 1 and its connection to the two scaffolding systems 2 and 3 can be seen and described in the following Figures.

Figure 2 shows a perspective view of a first embodiment of a connection component 1 according to the invention. The connection component 1 shown has the following three main areas arranged from top to bottom: The first connection area 11 is arranged at the top. Adjacent below the first connection area 11 is the fastening area 12. Again below the fastening area 12 is a second connection area 13. The first connection area 11 provides one or more interfaces for connection to a first scaffolding system 2. The first connection area 11 extends along a longitudinal axis LA. The first connection area 11 comprises an axis 111, which here is formed by a cylindrical tube section. A connection disk 15 is arranged on the outer peripheral surface of the axis 111. The connection disk 15 has a flat connection surface 151, which in the figure is oriented upwards. In the connection surface 151, a plurality of connection recesses 152 are arranged here, which project into the connection disk 15. The connection disk 15 is intended for connection to scaffold elements of the first scaffold system 2. The connection disk 15 is modeled after a connection disk which is used in the first scaffold system 2 as an interface between the scaffold elements. The receptacle 1111 is located inside the shaft 111. The receptacle 1111 is formed here by the hollow interior of the shaft 111 and extends along the entire axis along the longitudinal axis LA. The receptacle 1111 has a circular cross-section here. Scaffold elements of the first scaffold system 2 can be inserted into the receptacle 1111 to establish a positive connection with the connection component 1. An insertion opening 14 is arranged on the shaft 111 between the connecting disk 15 and the fastening area 12. A plug-in element can be inserted through this insertion opening 14, which then protrudes into the shaft wall and a recess in a scaffold element in the receptacle 1111 of the first scaffold system 2. By means of this insertion, a scaffold element of the first scaffold system 2 can be fastened to the connecting component 1 in a direction parallel to the longitudinal axis LA. The second connection area 13 is arranged on the side of the connecting component 1 shown below. The second connection area 13 also serves to connect the connecting component 1 to the first scaffold system 2. The second connection area 13 is also largely formed by a cylindrical tube section. The second connection zone also has a receptacle 131 within it, which is accessible from below and is arranged on the axis 132. The receptacle 131 has a diameter identical to that of the receptacle 1111, also extends along the longitudinal axis LA and is arranged coaxially with the receptacle 1111. In the embodiment shown, it is possible to produce part of the first connection zone 11 and the second connection zone 13 from a common continuous pipe section. Also in the wall of the second connection zone 13 there is an insertion opening 14 which, like the insertion opening 14 in the first connection zone 11, serves to connect or secure with a scaffold element of the first scaffold system 2. In the embodiment shown, part of the second connection zone 13 is arranged within the fastening zone 12. This results in a compact and stable overall construction of the connection component 1. In the central region of the connecting component 1, the fastening region 12 is arranged, which serves as an interface for the connection to a second scaffolding system 3. The fastening region 12 has a stop 121 on its upwardly facing side. In the embodiment shown, this stop 121 is formed by a flat rectangular cover plate 1211 and a partial region of the two insert plates 123. The cover plate 1211 directly adjoins the axis 111 of the first connection region 11. The cover plate 1211 has its largest surface oriented perpendicular to the longitudinal axis LA. In a top view from the direction of the longitudinal axis LA, the cover plate 1211 is rectangular, with the longest side of the rectangle extending in the same direction in which the two insert plates 123 are arranged radially with respect to the longitudinal axis LA. The stop also comprises the upper partial regions of the two insert plates 123. Each insert plate 123 is T-shaped in a top view. The upper bar of the T belongs to the stop 121. On the side of this bar of the T-shaped insert plates 123 pointing downwards in the figure, flat surfaces are arranged, which together form the first support surface 121a of the stop 121. When the connection component 1 is connected to the second scaffolding system 3, the first support surface 121a rests on a scaffolding element and forms a stop for positioning the connection component 1 relative to the second scaffolding system 3. The downward-pointing side of the cover plate 1211 in the representation has the second support surface 121b of the stop 121 in the area protruding from the two insert plates 123. When connected to the second scaffolding system 3, in the embodiment shown, the first support surface 121a or the second support surface 121b can be placed on a scaffold element of the second scaffolding system 3. The choice of one of the two support surfaces 121a or 121b depends on which of the two insert interfaces 1221 or 1222 described below is used for the connection.

In the embodiment shown in Figure 2, the fixing zone 12 comprises two insertion interfaces 1221 and 1222. Parts of these insertion interfaces 1221 and 1222 rest on one or more scaffold elements of this second scaffold section 3 when the connection component 1 is connected to the second scaffold section 3. The first insertion interface 1221 has a partial zone on two opposite sides of the longitudinal axis LA in each case. The first insertion interface 1221 here comprises two first stop surfaces 1221 a and 1221 b which are oriented parallel to each other and which point towards the front right and the rear left in the illustration. The two first stop surfaces 1221 a and 1221 b are here together formed by the two insertion plates 123. As already described above, in the embodiment shown, the two insert plates 123 are T-shaped. Each insert plate 123 has a fixing surface 123a pointing radially inward in the direction of the longitudinal axis LA. Each insert plate 123 is connected to the inner region of the connection region 12 via the connecting surface 123a. In the embodiment shown, this inner region is formed by a pipe section. The two insert plates 123 are fixed here by a welded connection to the pipe section arranged inside. Next to the fixing surface 123a, a narrow edge surrounds the entire insert plate 123. This edge forms the edge region 123b. Partial regions of the two first stop surfaces 1221a and 1221b are arranged in partial regions of this edge region 123b. In other words, the first of the first stop surfaces 1221 a is formed as a whole by partial regions of the edge region 123 b of the two insert plates 123 pointing towards the front right. The second of the first stop surfaces 1221 b is formed as a whole by partial regions of the edge region 123 b of the two insert plates 123 pointing towards the rear left. Thus, partial regions of the two stop surfaces 1221 a and 1221 b are located on both sides of the longitudinal axis LA, spaced apart from each other on both sides of the tube section arranged inside. As a result, the two first stop surfaces 1221 a and 1221 b together provide a spatially distributed stop surface which, when connected to the second scaffolding system 3, allows a good transmission of force and torque between the connecting component 1 and the second scaffolding system 3. When using the first insertion interface 1221 and the two first stop surfaces 1221a and 1221b, the first support surface 121a is used to support the connection component 1, which is arranged directly adjacent and adjacent to the first stop surfaces 1221a and 1221b on the insertion plates 123. Between the two insertion plates 123 in the pipe section arranged between them, two safety recesses 12211 are arranged one above the other, which belong to the first insertion interface 1221. The two safety recesses 12211 extend into the entire insertion area 122 and can be used for a positive connection or for securing the connection component 1 with the second scaffolding system 3. The fastening area 12 comprises a second insertion interface 1222. This second insertion interface 1222 has two second stop surfaces 1222a and 1222b. These two second stop surfaces 1222a and 1222b point towards the front left and rear right in the illustration and are each arranged on one side of an insert plate 123 opposite the fixing surface 123a. The distance between the two first stop surfaces 1221 a and 1221 b and the two second stop surfaces 1222a and 1222b differs from each other. Due to these different distances, the two insertion interfaces at 1221 and 1222 are dimensioned differently and can therefore be used as connection interfaces for connecting to scaffold elements of different sizes of the second scaffold system 3. The advantage here is that the two insert interfaces 1221 and 1222 are ready for use and are fixedly arranged on the connecting component 1, offset by 90°. When constructing a scaffold section 100, the connecting component 1 can simply be rotated about the longitudinal axis LA in order to select the appropriate insert interface 1221 or 122 for the connection. Thus, the connecting component 1 in the illustrated exemplary embodiment can be very easily adapted to different scaffold elements of the second scaffold system 3. At the same time, the shown arrangement of the components with the two T-shaped insert plates 123 connected to a tube section is very compact and stable, whereby high load capacities of the connecting component 1 are achieved. When the second insertion interface 1222 and the two second stop surfaces 1222a and 1222b are used, the second support surface 121b adjacent to these two second stop surfaces 1222a and 1222b is used to support the second scaffolding system 3. In the area of the second support surface 121b, the stop 121 projects further beyond the longitudinal axis LA in the radial direction than in a direction offset by 90°. The cover plate 1211 has its longest side in a plan view from the direction of the longitudinal axis LA between the partial areas of the second support surface 121b. This ensures that in the area of the second insertion interface 1222 there is a sufficiently large projection of the second support surface 121b onto the two second stop surfaces 1222a and 1222b. At the same time, an unnecessary protrusion or projection of the stop 121 in the area of the first insertion interface 1221 and the two first stop surfaces 1221a and 1221b is avoided. This results in a lightweight and slim construction of the connecting component 1. Due to the smaller protrusion of the stop 121 radially to the longitudinal axis LA in the area of the first insertion interface 1221, the fastening area 12 is made sufficiently narrow in this direction to be inserted into a narrow grid dimension of the second scaffolding system 3 without collisions with elements of this second scaffolding system 3. The second insertion interface 1222 here comprises a safety recess 12211, which here passes through both insertion plates 123 and extends at right angles to the two second stop surfaces 1222a and 1222b. In the illustrated embodiment, the cover plate 1211 of the stop 121 is connected to the first connection zone 11 and to the two insert plates 123 by welded connections. The axis 111 of the first connection zone 11, the inner region of the fixing zone 12 arranged between the insert plates 123 and the axis 132 of the second connection zone 13 are formed in the illustrated embodiment by a common continuous pipe section. This common pipe section has a constant internal cross section on its inside.

Figure 3 shows a representation of a second embodiment of a connection component 1 according to the invention in a) a side view, b) a top view and c) a perspective view. The second embodiment of a connection component 1 shown in Figure 3 differs from the first embodiment shown in Figure 2 in the design of the fixing zone 12. Unless otherwise described, reference is made to Figure 2 and the associated description for details of the second embodiment. The first connection zone 11 is identical to the first embodiment of Figure 2. The second embodiment of Figure 3 furthermore has a second connection zone 13, which is also configured almost identically to the first embodiment of Figure 2. Furthermore, the second connection zone 13 in Figure 3 has several insertion openings 14. The insertion area 122 of the fastening area 12 also comprises here two insertion interfaces 1221 and 1222, which are provided for selectively connecting the connection component 1 with a scaffold element of the second scaffold system 3. The two insertion plates 123 of the illustrated embodiment differ in shape from the insertion plates 123 of the first embodiment. The two second stop surfaces 1222a and 1222b are curved here and arranged symmetrically with respect to the longitudinal axis LA. The fastening surfaces 123a are also curved in the illustrated embodiment, so that they rest on a large area in the cylindrical tube section forming the interior of the fastening area 12. The two insertion plates 123 are connected to this cylindrical tube section by means of welded connections. The first insertion interface 1221 is also offset by 90° relative to the second insertion interface 1222 in a top view of the longitudinal axis LA. The two first abutment surfaces 1221 a and 1221 b are also formed here by the edge regions 123b of the two insertion plates 123. The edge regions 123b are also curved in some regions. Both the first insertion interface 1221 and the second insertion interface 1222 have at least one safety recess 12211 which completely penetrates the fixing region 12. In this embodiment, a threaded region 123c is introduced into each of the two insertion plates 123. This threaded region 123c is intended to facilitate the insertion of an insertion element 33 into the safety recess 12211 of the second insertion interface 1222. In the central top view b), the threading area 123c is protruded in a semicircle from the insert plate 123. In the side view a) and in the perspective view c) it can be seen that this shape acts as an insert chamfer or bevel around the safety recess 12211. In a top view from the direction of the safety recess 12211, the threading area 123c is arranged coaxially with the central axis of the safety recess 12211. In addition to the positive connection to a scaffold element of the second scaffold system 3, the threading area 123c, which represents a recessed cut in the insert plate 123, can also be used. In the second embodiment shown in Figure 3, the first support surface 121a and the second support surface 121b are arranged on the cover plate 1211 of the stop 121. Thus, both support surfaces 121a and 121b lie in the same plane here. Also in the second embodiment, the distances between the two first stop surfaces 1221 a and 1221 b and the two second stop surfaces 1222a and 1222b differ.

The scaffold sections 100 can be seen in the following drawings. The scaffold section 100 of Figures 4 and 5 shows the first embodiment of a connection component 1 of Figure 2, and Figures 6 to 9 show the second embodiment of a connection component 2 of Figure 3.

Figure 4 shows a perspective view of a first embodiment of a scaffold section 100 according to the invention. Figure 4 corresponds to a partial region of the scaffold section 100 of Figure 1. In the illustrations, a connection component 1 according to the first embodiment can be seen approximately in the center. The first connection region 11 is connected to a scaffold element of the first scaffold system 2. The second connection region 13 is also connected to a scaffold element of the first scaffold system 2. In contrast, the fastening region 12 is connected to a scaffold element of the second scaffold system 3. For details that are covered by the scaffold elements of the second scaffold system 3 in Figures 4 and 5, reference is made to Figure 2 and the associated description.

The first upwardly facing connection zone 11 is connected to a vertical post 21 of the first scaffolding system 2 via an adapter piece 211. The adapter piece 211 comprises a protruding region which is inserted into the receptacle 1111 of the first connection zone 11. A shoulder of the adapter piece 211 rests on the upper end face of the first connection zone 11. The adapter piece 211 further has a further upwardly facing protruding region which is inserted into the lower end of the vertical post 21. A shoulder is also arranged on the adapter piece 211 on the side facing the vertical post 21 on which the end face of the vertical post 21 rests. In the embodiment shown, the force is transmitted in the vertical direction as long as the forces are transmitted from the vertical post 21 to the connection zone 11 via the two shoulders of the adapter piece 211. Alternatively, it is possible to arrange a protruding area directly on the vertical post 21, which is then inserted into the receptacle 1111. Due to the visible height of the adapter piece 211, an adjustment of the effective total length of the connection component 1 can also be made, whereby the connection component 1 can be easily adapted to the grid dimensions of different first scaffolding systems 2. A vertical post 21 is also connected to the second connection area 13 arranged below. Here too, an adapter piece 211 is used for the connection. However, the adapter piece used in the second connection area 13 does not have shoulders like the adapter piece 211 used in the first connection area 11. The adapter piece 211 placed below is inserted both into the receptacle 131 in the second connection area and into the interior of the vertical post 21. The lower adapter piece 211 simply aligns the two components with each other so that their end faces rest directly on each other. Forces in the vertical direction are therefore transmitted directly between the end faces of the components. A small gap is marked out in the illustration so that the adapter piece is visible. When in use, this gap is not visible. The second scaffolding system 3 is represented here by a horizontal beam 31. The second scaffolding system typically comprises additional scaffolding elements which are not shown here. The horizontal beam 31 comprises two support rails 31a and 31b which are spaced apart and aligned parallel to each other. The two support rails 31a and 31b here have a C-shaped cross section and are oriented towards each other such that the longitudinal sides of the C lie opposite each other. The two support rails 31a and 31b are positioned relative to one another by means of at least two spacers 34, not shown, which are arranged between the two support rails 31a and 31b. The two support rails 31a and 31b have several recesses in which further elements can be connected to the horizontal beam 31. A forward-facing receiving recess 32 can be seen, which runs through both support rails 31a and 31b and has a circular cross-section here. In the embodiment shown in FIG. 4, the connecting component 1 is connected to the horizontal beam 31 via its first insertion interface 1221. To establish the connection, the insertion area 122 is inserted between the two support rails 31a and 31b until the first support surface 121a abuts and rests on both support rails 31a and 31b. This stop indicates the correct position of the connecting component 1 with the horizontal beam 31. In the inserted state, the first two stop surfaces 1221 a and 1221 b each rest on an inwardly facing wall of one of the support rails 31 a and 31 b. There is thus a large total contact surface between the connecting component 1 and the horizontal beam 31, which enables good transmission of force and torque between the two components. In the position shown, a safety recess 12211 of the connecting component 1 is aligned with a receiving recess 32 of the horizontal beam 31, so that the two components can be connected to each other in a positive-fitting manner via an insertion element 33. Such an insertion element 33 is shown in simplified form in FIG. 4 as a cylindrical pin. As can be seen in Figure 4, the stop 121 and the insertion area 122 do not protrude beyond the horizontal beam 31 in any part of the transverse direction. This does not hinder the fixing of other scaffold elements to the horizontal beam 31 and reduces the risk of injury to persons.

Figure 5 shows a perspective view of a second embodiment of a scaffold section 100 according to the invention. Unless otherwise stated, the second embodiment corresponds to the embodiment shown and described in Figure 4. The second embodiment in Figure 5 comprises a larger horizontal beam 31 of a second scaffold system 3, which is connected to the connection component 1. This horizontal beam 31 also comprises two support rails 31a and 31b, which, however, are larger than in Figure 4 and are also arranged at a greater distance from each other. For this reason, the connection component 1, which is the same connection component 1 as in Figure 4, is connected to the horizontal beam 31 in Figure 5 via the second insertion interface 1222. The two second stop surfaces 1222a and 1222b therefore rest on the inside of the inwardly facing surfaces of the two support rails 31a and 31b. The second support surface 121b, which is arranged on the underside of the cover plate 1211, rests here on the upwardly facing surfaces of the two support rails 31a and 31b. In Figure 5, the second insertion interfaces 1222 and the two support rails 31a and 31b are positioned relative to one another such that the safety recess 12211 in the insertion area 122 is aligned with a receiving recess 32 in the horizontal beam 31. In this case, too, the connected components can be fixed by means of an insertion element 33. In a direct comparison between Figures 4 and 5 it can be clearly seen that the connecting component 1 can be connected to two horizontal beams 31 of different sizes simply by rotating it around its longitudinal axis by 90°. The connecting component 1 can therefore be handled flexibly and ensures a stable, safe and ergonomic connection to different horizontal beams 31 of a second scaffolding system 3.

Figures 6, 7, 8 and 9 each show scaffold sections 100, each of which comprises a connection component 1 according to one of the second embodiments shown individually in Figure 3. For reasons of simplicity, in these scaffold sections 100 the connected scaffold elements of the first scaffold system 2, which are connected to the first connection zone 11 and/or a second connection zone 13, are not shown. Figures 6, 7, 8 and 9 show the connection of the fixing zone 12 to a horizontal beam 31. For elements covered in these views and therefore not shown, reference is made to Figure 3 and the associated description.

Figure 6 shows a side view of a third embodiment of a scaffold section 100 according to the invention. Figure 6 shows a side view where a connecting component 1 is connected to a horizontal beam 31 via its second insertion interface 1222. Here too, the horizontal beam 31 has two supporting rails 31a and 31b arranged at a distance from one another. In Figure 6 two spacers 34 arranged one above the other can be seen, which connect the two supporting rails 31a and 31b to one another and adjust their distance from one another. In the state shown, the two second stop surfaces 1222a and 1222b rest on the inside of the walls of the two supporting rails 31a and 31b. Furthermore, the first support surface 121a of the stop 121 rests on the horizontal beam 31.

Figure 7 shows a perspective view of the scaffold section 100 of Figure 6. In this perspective view it can be seen that the two spacers 34 are arranged offset in the longitudinal direction with respect to the connecting component 1. In the perspective view, several receiving recesses 32 can be seen, which are arranged at a distance from one another in the longitudinal direction of the horizontal beam 31. At any of the points where a receiving recess 32 is provided, a connection of the connecting component 1 and the horizontal beam 31 can be realized by inserting an insertion element 33.

Figure 8 shows a side view of a fourth embodiment of a scaffold section 100 according to the invention. Figure 8 corresponds, unless otherwise stated, to the embodiment of Figure 6. In contrast to the embodiment of Figure 6, the horizontal beam 31 in Figure 8 is smaller and the distance between the two support rails 31a and 31b is smaller than in Figure 6. Therefore, the connection component 1 in Figure 8 is connected to the horizontal beam 31 via the first insertion interface 1221. For this purpose, the two first stop surfaces 1221a and 1221b abut on the inside of opposite walls of the support rails 31a and 31b. The first abutment surface 121a of the stop 121 rests on the two support rails 31a and 31b.

Figure 9 shows a perspective view of the scaffold section 100 of Figure 9. In direct comparison with Figure 7, it can be seen here that the connecting component 1 has simply been rotated by 90° with respect to the longitudinal axis LA in order to adjust to the difference in the distance between the support rails 31a and 31b. Even in scaffold sections 100 in which a connecting component 1 according to the second embodiment is used, no part of the fastening area 12 protrudes in the transverse direction beyond the horizontal beam 31. The connecting component 1 and the horizontal beam 31 can also be connected to each other in a form-fitting manner in the exemplary embodiment shown in Figures 8 and 9 with an insertion element 33, as long as the insertion element 33 is inserted into the safety recess 12211 and a receiving recess 32 aligned with it.
