Definitions

the present invention relates to a guideway device in modular construction with at least three separate longitudinal section modules to be connected to one another, consisting of two head modules and at least one intermediate module, wherein the respective longitudinal section module has a supporting structure, wherein at least two of the longitudinal section modules are connected to one another by means of a supporting module connection designed to connect the supporting structures of at least two longitudinal section modules to one another, in particular abutting at the front, wherein the supporting module connection has a plurality of sheet metal connections. Furthermore, the present invention relates to a method for modularly assembling such a guideway device, in particular when using non-materially bonded connecting means.
the present invention also relates to the use of a plurality of sheet metal connections to form a supporting module connection for connecting the supporting structures of at least two longitudinal section modules of a guideway device provided in modular construction.
the invention relates to a device and a method according to the preamble of the respective independent claim.
the components to be assembled in the head areas of the escalator must usually be installed in an inclined position of the head areas, especially if the supporting structure of the escalator has already been created and is present over the entire intended length of the escalator and the angular alignment of an intermediate section between the head modules relative to the head modules is already predefined, i.e. if the intended gradient/inclination of the escalator has already been structurally implemented.
a large part of the assembly/installation measures usually take place in this state, with corresponding requirements for cranes, support arms or similar assembly aids designed for large loads.
Examples include the publications EP 3 426 588 B1 and EP 3 426 589 B1 which each describe a device and a method for producing a passenger transport system based on several joining steps. Furthermore, the EP 3 724 118 B1 which indicate measures intended to facilitate order picking or other measures preparatory to production or the production process, particularly in the case of escalators.
the task is to provide a device-technical or structural design and a corresponding method with which escalators or general guideway devices can be assembled as simply as possible and the load-bearing components, in particular of a respective support structure comprising side walls, can be connected to one another in a particularly advantageous manner. It is also the task to design a concept for the structural design of guideway devices and a mounting/assembly method dependent on this in such a way that the guideway devices can be completed with the highest possible standardization and efficiency on the one hand and with the highest possible variability on the other.
a guideway device is provided in modular construction with at least three separate longitudinal section modules to be connected to one another (to be married to one another to form a complete guideway device), consisting of two head modules and at least one intermediate module, wherein the respective longitudinal section module has a supporting structure (in particular with load-bearing components, which can at least partially also be provided in a lattice-like manner), wherein at least two of the longitudinal section modules are connected to one another by means of a supporting module connection set up to connect the supporting structures of at least two longitudinal section modules to one another, in particular at the end face, wherein the supporting module connection has a plurality of sheet metal connections which are intended contact adjacent support structures of neighboring modules and overlap in particular in the axial direction (particularly in the case of lateral surface contact/application), whereby the respective sheet metal connection has a plurality of fastening axes or fastening holes, each of which defines a fastening point for positive/positive connection means on one of the neighboring longitudinal section modules.
the invention it is therefore proposed to dispense with classic welded connections at least essentially, or optionally completely, when connecting the support structures of the individual modules.
this also makes it possible to realize the advantages achieved in connection with the modular construction of the support structure up to the final assembly or up to a phase of assembling the entire support structure (guideway device with full longitudinal extension), in particular also in connection with a force-fitting/positive connection, realizable flexibility and variation advantages, e.g. thanks to manual assembly, for example in connection with small batch sizes or small quantities of small series production.
the type of module connection described here enables decoupling from a certain type of assembly aid or welding robotics or similar production equipment, so that the respective production can be realized even more independently of a certain location or equipment of an assembly hall.
the sheet metal connections described here can also be used to create predefined/predefinable gap dimensions in a comparatively simple manner, which are advantageous, for example, when a certain tolerance range is required, e.g. for the purpose of fine adjustment and compensation of unexpected deviations, or when an additional material connection is subsequently required at individual points.
gap dimensions provide the greatest possible variability with the greatest possible accuracy, particularly in combination with a frictional connection and the most precise possible relative positioning of the modules for the connection process.
the present invention provides both an advantageous process and an advantageous device-technical structure, in particular such that the each longitudinal section module can be arranged and supported in a predefined/predefinable manner with respect to the relative position to at least one further longitudinal section module, in particular by means of a plurality of metal sheet connections acting in a force-fitting manner between the support structures to be connected, whereby a comparatively high degree of accuracy can also be ensured when positioning relative to one another (in particular in conjunction with reference recesses provided integrally on the support structures).
this makes it easier to handle and hold the individual modules, and on the other hand, it can also make the process of connecting/marrying modules in pairs easier.
guideway device refers primarily to escalator devices (in particular including moving walkways) and moving walkway devices (the latter in particular in a stepless design in an at least approximately flat alignment or with a negligible gradient) as well as related passenger transport devices with a continuously rotating transport device.
a guideway device comprises, for example, segments or units forming the transport device, in particular steps or pallets, which are connected to driven chains or comparable Drive means and guided in guide rails.
the guide rails as well as a/the chain (or a similarly acting traction means) and other components of the guideway device are held, for example, within load-bearing constructions or support structures that extend essentially laterally in the axial direction, which are usually made up of two side wall units that are opposite one another and are connected to one another via crossbeams and optionally also a floor unit, and can also include struts arranged in a lattice-like manner.
the term "guideway device” also refers in particular to modularly constructed guideway devices that are modularly constructed from several longitudinal sections or longitudinal section modules, each with an individual or longitudinal section-specific support structure, and can be assembled/mounted in modules.
the guideway devices described here can also each comprise moving walkway devices, i.e. guideway devices that are at least approximately horizontally aligned without steps but with individual guideway elements that are not intended to overcome an incline but form a largely flat route; in this respect, a reference to a bend or an inclined section is to be understood here to mean that the corresponding section is described largely independently of any incline actually realized.
the general term "assembly” or the more specific term “final assembly” generally refers to the assembly of the entire/complete support structure of the guideway device, which can also include all of the intended longitudinal section modules (two head modules and at least one intermediate module); this final assembly is also described here as a pairwise modular connection/marriage of the support structures of at least two longitudinal section modules, or at least comprising this connection step.
the term "assembly” can also include preparatory steps such as picking/providing/keeping components ready for a respective longitudinal section or module or for the entire guideway device; according to the present disclosure, the invention primarily relates to steps and aspects that are downstream of picking, i.e. do not include picking in the narrower sense.
module refers specifically to the assembly or assembly of only certain individual modules or their components in the corresponding module, for example specifically in the case of a head module, where, for example, components of a/the drive are installed in the upper head module, or guides, rails, cladding parts or Components of the balustrade are (pre-)assembled in only one of the modules.
the assembly of components can be carried out at least partially in a phase in which the modules are still handled separately from one another, or in a phase in which the modules are already married to one another; this variation option affects, for example, the individual steps/pallets; in this respect, too, the use of the term "assembly" is not to be understood as restricting certain phases of the process of creating the complete guideway device or its supporting structure.
longitudinal section module is to be understood in the sense of the present disclosure generally as a load-bearing longitudinal module of the guideway device, i.e. as a module that forms a longitudinal or length section of the guideway device and provides the support structure for it (i.e. a component of the guideway device in the corresponding length range that is at least structurally complete).
This term therefore includes the terms “head module” and “intermediate module”.
head module refers to a module arranged at one of the ends of the guideway device and refers optionally to both types of head modules (upper and lower head module, also referred to as upper part and lower part); in this respect, this term can equally refer to the module at the upper or lower end of the guideway device.
head modules In guideway devices designed as escalators, head modules usually extend over one or the angle of inclination of the guideway device and thus span the bend or the transition from the inclined longitudinal section to the respective horizontal longitudinal section.
the term "platform section” refers to the section of the respective head module which, in the intended arrangement, is aligned at least approximately in a horizontal plane; in this respect, when describing the arrangement/alignment of the respective head module, reference is also made to the alignment of this platform section (or its main extension plane), in particular if or when the absolute length of the platform section is greater than the absolute length of the inclined section.
the "connecting inclined section” (also referred to as a stub in the specialist literature) is to be understood in particular as the inclined/inclined section intended for connecting/marrying with another longitudinal section module, and this inclined section can be more or less long depending on the function of the respective head module; this means that the individual modules are intended to be connected to one another in the area of a to connect a longitudinal section that is inclined as intended; if several intermediate modules are provided, the intermediate modules are first connected/married to one another, or the respective head module and intermediate module are first connected, depending on the process preference.
the general term “longitudinal section” can refer either to a longitudinal section module or to a specific longitudinal section, particularly of the head module (i.e. platform section or inclined section).
longitudinal section compared to the term “longitudinal section module” refers, unless further specified, equally to the head sections and the at least one intermediate section and is used according to the present disclosure when modularity or a modular design or a strictly modular process is not necessarily required or can also be varied or modified according to the invention, or when reference is made to a process or a device-related state which is still prior to the intended modular construction of the individual modules, e.g. relating to connecting individual longitudinal sections of a head module to form the entire head module.
individual longitudinal sections are referred to without explicitly referring to them as longitudinal section modules, not only the individual modules but also longitudinal sections of an individual module can be affected, in particular a platform section (e.g. first longitudinal section) and an inclined section (e.g. second longitudinal section) of a head module, for which two sections a specific connection process can be provided (in particular in the area of the bend);
a platform section e.g. first longitudinal section
an inclined section e.g. second longitudinal section
individual longitudinal sections of a module can be positioned relative to one another by means of form-fitting contours, e.g. in connection with a material-locking connection of these longitudinal sections to create the entire supporting structure of the respective module.
A/the support structure of a/the guideway device or of a/the respective module can essentially be formed by opposing side wall units and cross members (also referred to as crossbars) connecting them, wherein a/the side wall unit is formed by at least one side wall and in particular by an upper flange and/or a lower flange; the modular manufacturing process described here can also include the connection of a floor unit to the side wall units; however, it has been shown that such a floor unit does not necessarily have to fulfill a support function, but is designed, for example, with regard to the function of collecting oil from a/the drive and, if necessary, draining it away, or is designed in an optimized manner with regard to a cover and/or accessibility from below to the support structure or the guideway device; in this respect, the floor unit is to be understood as an optional structural unit, which can also be functionally provided separately from the supporting structure, but which can optionally also take on an additional supporting load-bearing function if desired in individual cases.
side wall refers to a side structure which, for example, runs flat in only one side plane at least in sections, but is alternatively or additionally formed and/or reinforced at least in sections by profiles, struts or supports extending beyond one/the side plane.
the side wall is formed from structural elements or structural sections which, as flat structural sections, absorb forces in several directions and/or, as rod-shaped or strut-like structural parts/sections/elements, absorb the respective forces only along the longitudinal extension specified by the orientation (tension or compression); such components of the load-bearing structure can also be referred to by the English term “truss member” or "truss section”, whereby according to the present disclosure, a truss-like structure does not necessarily have to be present; the term “truss” can nevertheless be considered appropriate here, because the side wall usually has a truss-like structure at least in sections, i.e.
the side wall is thus designed, for example, as a closed surface, as a pure framework or as a structure with parts (or sections) of closed surfaces and parts with a framework structure.
the load-bearing structural parts/sections of the side wall are made of flat material, in particular sheet metal, e.g. structurally flat sections or stiffening (in particular) curved L- or U-profile sections in the area of welded connections to other structural parts/elements/sections.
a “side wall unit” comprises the side wall described here and belts associated with this side wall, in particular an upper belt and a lower belt, wherein the belts can be formed integrally with the side wall, integrated or separate from one another. These belts are alternatively also referred to as bands.
the respective side wall/unit can also be understood as a side wall/unit provided in modules, depending on the reference to a/the respective phase of the manufacturing process of the individual modules or the entire guideway device.
the term side wall unit can refer to the entire side structure comprising the upper and lower chords, and the term side wall can refer to the side structure arranged between the upper and lower chords.
chords refer to the longitudinal direction in the area of an upper edge or a lower edge of the side wall extending structural parts/elements or corresponding load-bearing sections for absorbing loads in the longitudinal direction of the guideway device, in particular bending loads, which primarily lead to tensile stresses in the lower chord and to compressive stresses in the upper chord.
the chords are preferably designed as profiles or profile sections, in particular as L-profiles, U-profiles or hollow profiles and thus have a favorable area moment of inertia for absorbing the bending loads.
the chords therefore stiffen the supporting structure and form outer corner points, with the chords and/or the side walls optionally serving to attach further components of the guideway device.
the chords can also be designed as components separate from the side wall; however, at least some of the chords are preferably formed integrally with the side wall, for example by bending the side wall.
the upper chord is particularly preferably designed as a hollow profile with four walls, with two walls being formed by the L-shaped side wall made from flat material in this area, and two more of the walls being formed by a flat material component that is also L-shaped and separate from the side wall.
the lower chord is also preferably designed in a similar way as a hollow profile with four walls, with two walls being formed by the L-shaped side wall made from flat material in this area, and two walls being formed by the base unit that is also L-shaped and made from flat material in this area.
the components forming the walls are preferably welded to one another.
the upper chord and/or the lower chord can also be provided entirely in one piece with the side wall or entirely separately from the side wall (particularly in the sense of a process variation).
Structurally loadable is understood to mean a point or component of the supporting structure that is temporarily loadable to absorb at least the forces resulting from the dead mass of the guideway device or the corresponding module, e.g. in connection with individual assembly steps. This term is used, for example, in relation to the reference points described here.
load-bearing is understood to mean a component or a part (section) of the supporting structure which is designed to withstand the prevailing static and dynamic forces and moments, even under continuous loading over several years, when the guideway device is used as intended.
connecting means in the sense of the present disclosure is to be understood as a screw connection or a rivet connection, in particular a so-called locking ring bolt connection, in particular in connection with a connection between modules.
a person skilled in the art can specify whether such a preferred rivet connection or locking ring bolt connection should be replaced in individual cases or at individual connection points by, for example, a screw connection.
the rivet connection or locking ring bolt connection preferably comprises at least one visual inspection marking, in particular one that lifts off the material, by means of which the correct use of a tool or the correct fit of the connection can be easily checked.
the present invention is also based in particular on the concept that at least a significant portion of a side wall, an upper flange, a lower flange and/or the entire side wall unit, which defines the overall shape, is made of flat material, in particular sheet metal, with at least one reference point preferably being defined on the flat material.
at least one reference point or reference recess
the invention particularly preferably includes the teaching of introducing further references, in particular corresponding recesses (in the sense of additional component-specific assembly reference points) on the flat material in addition to the at least one reference point arranged in particular in the corresponding side wall during the course of the same processing method, on which further components can be arranged directly and thus in a defined position relative to the at least one (master) reference point with high accuracy.
references or reference recesses are also introduced in particular in areas of the flat material which can be subjected to further processing steps, in particular bending processes, following the laser cutting, whereby the referencing concept described here can also be implemented for multi-dimensional positioning in space with respect to at least two or all three spatial directions.
the invention includes the teaching that the reference point is defined by a circular recess or by its center, for example, on which further positioning devices (i.e. assembly aids such as side support units) can be clamped for positioning individual longitudinal sections or components, for example.
the respective component with the reference point or the entire module or the entire guideway device is raised at at least one reference point or supported about a reference axis formed by several reference points, e.g.
an upper chord or a lower chord can also be formed from a profile, whereby corresponding processing methods, in particular tube laser cutting methods, for forming a reference point and/or further references are also available for profiles.
components refers to components to be installed in the respective guideway devices or in the respective modules of the guideway device, e.g. relating to electrics, drive, guidance or the like. If a load-bearing function is to be fulfilled by a structural component, in particular for the intended continuous load, the term “load-bearing components” or structural parts/elements/sections is used in connection with the supporting structure.
metal sheet connection here highlights that individual sheet metal angle units or plate units of the metal sheet connection are intended and set up to connect the supporting structure sections made of metallic materials to one another; in this respect, the term “sheet metal” is not limited to purely metallic materials, but the connection technology described here can also be implemented for material combinations that only partially consist of metal.
the respective metal sheet connection is provided in the form of an L- or U-shaped sheet or as an unbent flat sheet.
This variation option also enables scaling with regard to the transferable forces (direction and amount) and promotes the high variability described here with at least approximately the same connection principle.
the supporting module connection comprises at least one sheet metal connection from the following group: sheet metal bracket unit, inner bracket, bent Angle piece, counter plate.
the respective sheet metal connection has a large number of oversized fastening holes or fastening slots, in particular with the respective slot in axial alignment (axially according to the main extension direction of the guideway device).
This facilitates the possibility of adjustment in a very advanced assembly phase, so that even in this phase, manufacturing inaccuracies, in particular with regard to the support structures, can be compensated for in a comparatively simple and streamlined manner with high accuracy.
the slots can also be provided in different fastening planes.
slots are also provided on the respective support structure section on at least one fastening axis instead of rotationally symmetrical through holes, depending on the spatial direction in which an adjustment option is to be specified structurally.
the expert can specify, in particular depending on the selected process details, on which fastening axes which of the connection components may have at least one slot.
the load-bearing module connection has positive/non-positive connecting means in the form of screw connections and/or rivet connections, in particular exclusively rivet connections in a preferred embodiment in each case as a locking ring bolt connection.
positive/non-positive connecting means in the form of screw connections and/or rivet connections, in particular exclusively rivet connections in a preferred embodiment in each case as a locking ring bolt connection.
this also facilitates manual assembly, so that the optionally maximum variability and flexibility can be ensured right up to the final assembly.
the expert can also make further specifications for a particularly preferred selection of connecting means, in particular also depending on whether the respective sheet metal connection is primarily intended to transmit shear forces or tensile forces in the direction of the fastening axis.
the locking ring bolt connections mentioned here are also referred to as rivet connections; optionally, a tear-off part can be provided as with classic rivets.
a tool exerts a tensile force (this can be done e.g. by a motor-controlled rotation and/or by a hydraulic actuation), whereby a deformation sleeve deforms a locking ring and connects it with a bolt in a form-fitting manner, whereby the connection force is The desired pre-tension is ensured. Visual inspection can also be made easier by material lifting effects when the end position is reached.
Such fasteners provide a high level of safety and also offer the advantage that essentially only frontal access is required in the axis of the respective fastener, so that the individual fastening points can be selected or specified in the design with even greater degrees of freedom.
the respective longitudinal section module has two opposite side wall units which extend in the intended vertical alignment from an upper flange to a lower flange, with at least two or at least three positive/frictional connecting means being provided on the upper flange and on the lower flange for each sheet metal connection and for each module, in particular in the form of locking ring bolt connections, with at least one centering/positioning means such as a dowel pin optionally being provided for each sheet metal connection or sheet metal angle unit. Last but not least, this also facilitates exact positioning in relation to the vertical plane.
the centering/positioning means can preferably be provided separately from the connecting means; at least some of the fastening holes in the sheet metal angle units can be oversized in diameter or, for example, designed as an elongated hole, so that the expert also has an adjustment/setting option with regard to exact alignment and positioning, if desired.
the supporting module connection comprises at least one sheet metal angle unit, which has at least one L- or U-shaped sheet and several fastening axes offset from one another in the corresponding plane (i.e. offset in two spatial directions), in particular at least eight fastening axes, with positive/non-positive connecting means being provided on each fastening axis, with the connecting means preferably engaging at least one counter plate, i.e. passing through at least one carrier/cross member element (in particular hollow profile or correspondingly shaped sheet metal material section) or through a flat material section of the supporting structure.
a three-dimensional design of the respective sheet metal angle unit can increase the strength, in particular in areas of high bending moments.
L-profiles are advantageously implemented for such sheet metal angle units extending three-dimensionally in two fastening planes, in particular in coordination with L-profile sections of the supporting structure.
the load-bearing module connection is a self-locking positive and/or force-fitting connection without material/fabric closure or without a material connection, in particular without a welded connection, in particular exclusively comprising connecting means in the form of locking ring bolt connections.
the connecting means described here are preferably designed as connecting means that are designed to connect the connecting partners or the corresponding material sections to one another so strongly (in particular to press them together) that the support structures of the modules are positioned and held relative to one another in a force-fitting/friction-fitting manner.
locking ring bolt connections offer great advantages, but rivets or screws can also be used optionally, for example, at least at some of the fastening points.
the supporting module connection provides an axial distance or gap between adjacent modules, in particular a distance that can be adjusted by means of the positive and/or non-positive supporting module connection, in particular adjustable by at least one of the sheet metal connections, e.g. by providing an elongated hole and/or specifying different centering/positioning points.
This also provides the option of optionally specifying a target position in a respective fastening plane or at the corresponding connection interface, e.g. also during the alignment of the modules relative to one another.
the adapter plates described elsewhere here can also advantageously be used in this context.
the load-bearing module connection provides a positive and/or force-fitting pairwise connection of at least one of the following components of adjacent longitudinal section modules to one another, in particular in at least two fastening/connection levels: adjacent side walls or side wall units, adjacent upper chords, adjacent lower chords.
This provides a high level of strength, particularly when the upper and lower chords are included, for example against high bending moments with a large longitudinal extension.
Flat material sections can also be connected to one another, whereby the flat material sections (e.g. sheet metal) can be provided integrally on the respective side wall unit, for example in the form of L-shaped sections welded together.
the supporting module connection ensures a positive and/or non-positive connection in at least two connection planes, in particular in two connection planes that are orthogonally aligned to one another. This facilitates maximization of strength even in the case of module connections that are comparatively simply constructed and, for example, act purely non-positively (in particular frictionally).
the supporting module connection connects at least two components or sections of a first of the longitudinal section modules as well as at least two components or sections of a second of the longitudinal section modules to each other and also ensures that the longitudinal section modules are connected to each other.
This also provides a particularly advantageous force transmission, particularly in the case of a structural design of the supporting structure which is at least partially (preferably even to a large extent) based on the use of flat material. For example, two L-shaped surface sections of adjacent side wall units are connected to each other in a force-fitting manner by means of the module connection.
the supporting module connection has at least one upper flange plate connection, in particular in the area of an upper flange of a respective side wall unit of the adjacent modules, and at least one lower flange plate connection, in particular in the area of a lower flange of a respective side wall unit of the adjacent modules, whereby a positive and/or non-positive connection of adjacent modules is ensured in at least two areas/sections of the respective support structure, in particular in the edge areas/sections of the support structure that are furthest apart from each other in the transverse/height direction.
This also enables an effective leverage effect over the entire cross-sectional height of the support structure.
a (load-)bearing module connection designed for the positive/non-positive connection of the support structures of at least two separate longitudinal section modules of a guideway device described above by means of several sheet metal connections in a positive and/or non-positive manner, in particular when the longitudinal section modules are arranged relative to one another at the end face, wherein the load-bearing module connection provides/defines an axial gap between adjacent longitudinal section modules, in particular an axial gap that can be adjusted by means of the sheet metal connections, i.e. a position tolerance in the longitudinal direction, in particular also when/by using connecting means in the form of locking ring bolt connections, optionally in combination with additional positioning/centering means.
the relative longitudinal position is specified at least on some of the metal sheet connections without additional positioning/centering means based solely on frictional engagement.
a method for modularly assembling a guideway device by providing and connecting at least two longitudinal section modules of the guideway device in a coordinated arrangement and alignment, wherein the guideway device is provided in a modular configuration with at least three separate longitudinal section modules consisting of two head modules and at least one intermediate module, wherein in order to carry out a pairwise connection/marriage of the longitudinal section modules, at least one load-bearing module connection consisting of a plurality of sheet metal connections on adjacent longitudinal section modules (at least in the axial direction) is provided overlapping on these modules, wherein one of the head modules is connected to the (corresponding) intermediate module in a form-fitting/non-positive manner, in particular when the front end sides of the paired modules are arranged abutting and axially aligned, for example with reference to reference points provided for the specific module, in particular by the module connection ensuring frictional engagement in several connection levels, in particular also when/by using the types of
At least one of the head modules for modular connection can be arranged and aligned in an orientation and/or arrangement that matches the orientation/arrangement of the at least one intermediate module, for example by means of the sheet metal connections themselves and/or by reference to correspondingly provided reference points on the respective module.
the respective metal sheet connection is attached to both adjacent longitudinal section modules by means of positive/non-positive connecting means, in particular by means of locking ring bolt connections.
positive/non-positive connecting means in particular by means of locking ring bolt connections.
this also enables standardization of the connecting means used, whereby it has been shown that locking ring bolt connections in particular are comparatively easy and quick to apply on the one hand, and on the other hand provide a high level of safety, in particular thanks to the possibility of a visual inspection, so that the optional, largely manual assembly described here does not have any disadvantages in this respect either.
the great variability and flexibility associated with the modular concept can also be managed well by choosing connecting means that can achieve a high level of safety and minimize potential sources of error.
the adjacent longitudinal section modules abut one another at the end or are kept at a distance from one another by means of the sheet metal connections (axial distance or adjustable gap).
This variation option can be provided by means of the sheet metal connections, e.g. in combination with elongated holes or similar tolerance compensation options in at least one dimension.
At least four positive/non-positive connecting means are provided for each sheet metal connection in a respective fastening plane (at least two per module), which are arranged two-dimensionally offset from one another in the fastening plane.
This increases the strength and can also increase safety, particularly at connection interfaces, which are of particular importance for the operational safety of the entire guideway device.
at least three positive/non-positive connecting means are provided for each sheet metal connection, arranged two-dimensionally offset from one another in the respective fastening plane, depending on the module.
At least one sheet metal connection comprises at least one flat butt plate, in particular made of sheet metal material, which is fastened in a form-fitting/non-positive manner to a respective side wall (unit) of adjacent modules.
This fastening in particular in a vertical plane inside or outside, also promotes a high moment of resistance to bending forces and can effectively contribute to the rigidity/strength, in particular in the case of a large longitudinal extension of the guideway device.
At least one metal sheet connection is brought into contact with an upper flange and/or a lower flange of a side wall unit of a respective longitudinal section module, for example also in at least two different planes. This also enables force transmission under the modules in an area of high loads and with good leverage against bending moments.
At least one metal sheet connection provided on an upper flange and/or a lower flange of a side wall unit of a respective longitudinal section module is provided as an L- or U-profile and is connected in a form-fitting/non-positive manner to the adjacent longitudinal section modules, in particular by riveting or screwing against a counter plate in at least two fastening points per level and longitudinal section module, in particular such that the metal sheet connection ensures a frictional connection that defines the relative positional relationship of adjacent modules relative to one another (in particular while maintaining an axial gap that can be predefined by means of the metal sheet connection).
L-profiles are advantageously used as profiles. Multiple flat material sections can optionally be used instead of L-profiles.
the optional adjustment with regard to a pre-definable axial gap also provides the possibility of reacting to possible manufacturing inaccuracies and, in particular, of further optimizing the alignment of the modules, which can be advantageously carried out in connection with purely (essentially) force-fitting sheet metal connections, e.g. in combination with at least one elongated hole in each case.
the degree of any desired additional form-fitting for each sheet metal connection can vary from Specialists can also specify the requirements individually, e.g. with regard to individual fastening levels or fastening points, e.g. only in a certain level on the upper and/or lower chord.
the sheet metal connection is mounted in such a way that the sheet metal connection ensures at least a force-fitting connection between two structural sections of the support structure extending at an L-angle in at least two differently aligned planes (in particular planes extending at 90° to one another), in particular by L- and/or U-shaped sheet metal angle units of the sheet metal connection being connected in a form-fitting/force-fitting manner to the structural sections in the at least two differently aligned planes.
This also provides high strength and rigidity.
the aforementioned object is also achieved by using a plurality of sheet metal connections to form a load-bearing module connection for connecting the support structures of at least two longitudinal section modules of a guideway device provided in modular construction with at least three separate longitudinal section modules to be connected to one another in a coordinated arrangement and orientation, consisting of two head modules and at least one intermediate module, wherein the sheet metal connections contact adjoining support structures of adjacent modules as intended and overlap at least in the axial longitudinal direction and are/are fastened to a plurality of fastening axes or fastening holes on the support structure of the respective longitudinal section module by means of positive/non-positive connecting means, in particular locking ring bolt connections (connecting/marrying in pairs), in particular also for positioning/aligning the modules relative to one another, in particular using the plurality of sheet metal connections to create a guideway device described above, in particular according to a method described above.
a guideway device in modular construction is provided with at least three separate longitudinal section modules to be connected to one another, consisting of two head modules and at least one intermediate module, wherein the respective longitudinal section module has a supporting structure, wherein at least two of the longitudinal section modules are connected to one another by means of a supporting module connection set up to connect the supporting structures of at least two longitudinal section modules to one another, in particular at the end with abutment, wherein the supporting module connection has a plurality of sheet metal connections which, as intended, contact and overlap adjacent supporting structures of adjacent modules, wherein the respective sheet metal connection has a plurality of fastening axes or fastening holes, each of which defines a fastening point for positive/positive connection means on one of the adjacent longitudinal section modules.
the invention further relates to a corresponding method for modular assembly of such a
a travel path device 10 (in particular escalator device) comprising at least three longitudinal section modules 11, namely an upper head module 11a and a lower head module 11b and at least one intermediate module (in particular a straight module without a bend) 11c, with which the head modules are connected.
the respective head module 11a, 11b has a platform section 11.1 (or landing section or first longitudinal section or end section) with a horizontal orientation as intended.
the platform section changes into an inclined section 11.3 (or second longitudinal section of the respective head module) with a tilted orientation as intended.
the support structure therefore spans an angle of inclination ⁇ , corresponding to the inclination between the platform section and the inclined section.
a free end 11.1a of the platform section marks the beginning or the end of the guideway device at its respective front end 11.4.
several interconnected intermediate modules can also be provided, so that the respective (first) intermediate module is/will be connected to at least one further intermediate module 11c' (advantageous length scaling based on a comparatively short basic module length unit of a standard intermediate module).
a/the support structure 15 of the respective longitudinal section module 11 is constructed in a conceptually comparable manner:
Opposite side wall units 17, in particular comprising at least one profile section bent from flat material are each formed from a side wall 17a, 17b and an upper band (upper flange section) 17.7 and a lower band (lower flange section) 17.9 and are connected to one another by means of crossbars 16.1 (e.g. cross members, in particular with a hollow profile).
the side walls 17a, 17b are preferably formed largely or optionally exclusively from flat material, which can be bent at least in edge areas and welded to further flat material sections. In this respect, any sectional structuring can also be provided from flat material sections, in particular without the need to install profile semi-finished products.
the support structure 15 can also have, at least in sections, a framework-like configuration of individual strut-like structural sections intended primarily for tensile or compressive loading, whereby such a framework-like design or orientation of the individual sections can also be individualized, in particular depending on the structural components selected in each case, in particular already in a phase of flat material processing.
a framework-like configuration also includes at least a portion or even essentially only flat material sections (instead of profiles specified by semi-finished product production). This is because it has been shown that this design, which is at least largely made of flat material, is particularly advantageous with regard to the modular production concept described here and the scalability favored in this context, not least with regard to the achievable accuracy.
the respective longitudinal section module 11 can also have a base unit 14, which, however, does not necessarily have to have a load-bearing function.
the base unit extends only two-dimensionally and rather only fulfills a panel function (whereby the base unit can also have recesses, for example, which make access to the support structure easier), optionally the base unit can also comprise bent profile sections (in particular L-shaped bent end areas) and be connected to the actual support structure 15 in a structurally stiffening manner.
the base unit can also comprise bent profile sections (in particular L-shaped bent end areas) and be connected to the actual support structure 15 in a structurally stiffening manner.
the respective completed module 11 can also have a balustrade 12 and a handrail 13 or the corresponding longitudinal section thereof.
At least one reference point 17.1 is formed in the respective side wall unit 17, which can be defined, for example, by a geometrically predefined (in particular laser-cut) reference recess 17.3 (in particular a material recess introduced by material processing).
a geometrically predefined (in particular laser-cut) reference recess 17.3 in particular a material recess introduced by material processing.
a significant part of the referencing during the relative and/or positioning of the individual components can advantageously be carried out via these reference recesses 17.3, which can also be repeated, for example, after a predefined length unit of e.g. two or three meters and can therefore be provided redundantly, optionally also concerning all handling and assembly steps downstream of the introduction of the reference recesses 17.3 up to the final creation of at least the support structure and optionally also the entire guideway device.
further assembly/fastening points 17.5 for at least one further component to be fastened to the support structure can also be provided or positioned relative to the corresponding reference point 17.1 (for example also predefined by laser cutting or a comparable precisely adjustable machining process), in particular with reference to reference points which are located in a height or length section of the corresponding Flat material sections are arranged for which a comparatively high (manufacturing) accuracy can be ensured, particularly in the context of laser cutting processes.
the reference points 17.1 can considerably facilitate the storage and handling (in particular a tilting movement) of the respective module 11, in particular in connection with connecting/marrying the modules in pairs, and increase the accuracy that could previously be achieved using comparatively simple and compact assembly aids (in particular in coordination with other assembly aids that enable comparably precise storage on the floor 1, such as side support units, by means of which predefined positioned coupling points are provided, via which the modules can be coupled to the reference recesses).
the individual modules 11 are connected to one another by means of form-fitting and/or force-fitting (load-)bearing module connections 30 or sheet metal connections 31 in a plurality of fastening axes 34, while the modules 11 are supported in the reference recesses.
This comparatively precise and yet easy-to-use connection technology is described in more detail elsewhere.
the reference recesses described here can also be used for the arrangement of adapter plates, in particular in a preparatory phase when positioning two modules face-to-face, before the modules are connected/married in a form-fitting/non-positive manner.
the adapter plates can be mounted on the reference recesses of a first module and facilitate flush docking of the adjacent (second) module, in particular by providing corresponding tapered guides (at least one) on the respective adapter plate; the adapter plates are advantageously mounted on the outside of the respective side wall, in particular at least approximately centrally with respect to the total height of the cross-section of the support structure.
a corresponding guide bolt can be mounted on the adjacent (second) module, in particular also on at least one reference recess, in particular also in the relative position described here relative to the support structure.
Such adapter plates can be provided in a simple and cost-effective manner, in particular from sheet metal.
the adapter plates can make it easier to connect the modules both when working with a pit (one of the head modules is tilted with its end section below the working level and reaches deeper than a machine hall floor into a pit and can optionally be supported there) and when working without a pit; when working without a pit, the working level can be used for the entire support structure (i.e. for all modules to be connected).
the head module to be tilted downwards is/will be positioned with its free end still above the floor of the machine hall; during this phase, at least the head module is suspended from a crane if necessary, so that the adapter plates can facilitate the alignment or at least the guidance of the module as it approaches the adjacent module up to abutment (or up to a gap specified/specifiable by the adapter plate).
the steps outlined here show that the form-fitting/force-locking connection concept for marrying the modules can be implemented in a very flexible and variable manner with high precision and with minimal assembly equipment, largely independent of location (i.e. both as a preparatory measure at the manufacturer's site and on a construction site for final assembly at the destination).
the respective adapter plate can be provided without any problem regardless of location and can also be designed so inexpensively that even a single use (if not reusable) can be priced in without any problems.

the present invention also makes it possible, in particular, to overcome disadvantages and handling difficulties associated with escalators 3 ( Fig.1 ) with standard construction, which require an inclined arrangement/alignment of all longitudinal sections or of the supporting structure already constructed over the entire longitudinal extent during a comparatively long phase of the manufacturing process.
the respective module can be supported against the ground at support points 11.11 provided/provided for the module on the supporting structure.
the support points 11.11 can be provided, for example, on the underside of the respective supporting structure and enable the respective longitudinal section module to be laid down/supported independently of support at the reference points, thus making handling even easier.
the support points can also be used to temporarily store or transport the entire supporting structure after completion.
the support structure 15 or the corresponding side wall can be provided with a tolerance-minimized height section 15.1 (middle, at least approximately centrally arranged between the upper and lower flanges), in which a comparatively high position accuracy or a comparatively small tolerance can be ensured, in particular if the corresponding support structure section is preferably formed in one piece from flat material.
a tolerance-minimized height section 15.1 (middle, at least approximately centrally arranged between the upper and lower flanges), in which a comparatively high position accuracy or a comparatively small tolerance can be ensured, in particular if the corresponding support structure section is preferably formed in one piece from flat material.
a comparatively large tolerance can also be uncritical. This also applies to a lower height section 15b of the support structure, in particular in the area of a/the floor unit.
the present invention is also based on the concept of enabling reference to this middle height section 15.1 during relative and/or absolute positioning by providing at least one, preferably at least two structurally loadable reference recesses in this middle height section, e.g. set up for support on side support units.
the support structure 15 has, for example, several structural sections 15.3 (in particular flat material sections) and several support structure units 16, each with several profiles 16.1 or profile sections 16.1a with a hollow cross-section (in particular sheet metal profiles or flat material profiles), e.g. square profile sections, L-profile sections and/or U-profile sections. Individual surface sections or struts of the support structure units 16 can also be provided for connecting opposite side wall units.
several support structure units 16 together form a longitudinal section module, e.g. if the intermediate module is to be composed of several similarly constructed support structure units 16 or is to be designed to be scalable and extendable.
recesses 16.2 can be structurally planned in the area of a connection interface/plane.
Adjacent side wall sections can preferably be connected to one another in a flat connection interface 18 by coupling corresponding form-fitting contours to one another, in particular for the purpose of subsequent material-locking connection at the connection interface.
a form-fitting coupling is provided in particular for defining a relative position for subsequent welding of adjacent longitudinal sections, in each case by means of a first form-fitting contour on a first longitudinal section and a corresponding second form-fitting contour (in particular negative form) on a second longitudinal section, wherein several individual flange plate couplings (flat, acting two-dimensionally) can also be provided for each connection interface, in particular at height positions that are as far apart as possible. This promotes a high level of positional accuracy and reduces the risk of tilting/tensioning.
FIGS 5A to 5C show several longitudinal section modules 11 of a modularly constructed and modularly assembled guideway device 10, namely Figure 5C a longitudinal section module 11b designed as a lower head module, Figure 5B an intermediate module Longitudinal section module 11c, and Figure 5A a longitudinal section module 11a designed as an upper head module.
the longitudinal section modules 11 each have a support structure 15 with two side wall units 17 and cross members 16.1.
a respective side wall unit 17 has at least one side wall 17a, 17b, an upper flange 17.7 and a lower flange 17.9.
the structure of the support structure 15 of the respective module consists largely of side walls or side wall units made of flat material.
the side wall 17a, 17b is essentially made of flat material at least in an external plane and/or at least over a middle height section 15.1 (the middle height section can certainly make up at least 75% or even at least 85% of the total height of the corresponding side wall/unit), with structural sections designed as structural posts and/or structural sections designed as simple diagonal or cross-shaped cross braces being formed in the flat material in the corresponding side wall plane or slightly offset from it through recesses made in the flat material.
the offset arrangement in several planes can be realized, for example, by bending the flat material in one piece, at a single angle or at multiple angles.
the structural sections designed as structural posts divide the side wall 17a, 17b or the corresponding side wall unit 17 into fields. Furthermore, support elements and cross struts 16.1 are arranged or fastened to the structural sections provided by the flat material, in particular welded or otherwise connected, e.g. by means of a material bond.
the respective side wall 17a, 17b is further preferably formed integrally in one piece with the corresponding upper flange 17.7 and the lower flange 17.9, at least in sections; in particular, the flat material forming the respective side wall 17a, 17b forms a first wall (or a corresponding flat material section) and a second wall of the upper flange 17.7 bent in an L-shape from the first wall; a third wall and a fourth wall of the upper flange 17.7 are formed by a further structural element or section formed from an L-shaped bent flat material and welded to the flat material forming the corresponding side wall 17a, 17b.
a first wall is formed on the lower flange 17.9 by the flat material forming the side wall bent in an L-shape from the side wall and a second wall is formed in an L-shape from the first wall; a third wall and a fourth wall of the lower chord 17.9 are formed by a bottom unit 14 which is bent into an L-shape at least in sections.
the structural design of the upper and lower chords can be based on the same design principle, but differ in details such as the cross-sectional geometry and/or area, in particular since the lower chord is primarily subjected to tensile stress and the upper chord is primarily or at least largely subjected to compressive forces.
This structural design in particular the use of flat material bent into an L-shape at least in individual sections, which is then used to form further profiles, also enables a good compromise between material use, strength, variability and precision. It has been shown that a particularly advantageous arrangement can be provided if several (preferably only two) flat material sections bent into an L-shape in the end area are welded together to form a closed (square) profile.
the supporting structures of the longitudinal section modules 11 are in the Figures 5A to 5C in combination with other (built-in) components of the guideway device.
the lower head module 11b has a comb plate, a base section and several guides for chain rollers, step/pallet rollers and/or handrails. Corresponding guide rails are also arranged on the intermediate module. The guide rails rest on structural sections (in particular made of flat material) of the support structure.
the upper head module has (in particular in addition to the components already present in the lower head module and/or intermediate module) a drive for driving a chain and optionally also a handrail circuit.
the upper head module 11a has a balustrade 12 with a handrail 13 arranged on it; the balustrade is connected to the support structure, as can be seen in particular from Fig. 5B visible.
the longitudinal section modules 11 each have reference points 17.1 or corresponding geometrically predefined (in particular circular) reference recesses 17.3 introduced into the flat material on the supporting structures 15 or side wall units 17 or side walls 17a, 17b ( Fig. 5B ).
the reference points 17.1 are partially covered by side support units 44 which are predefined positioned/positionable on support and movement devices 40a, 40b and which are connected by means of coupling units 46 ( Fig. 5C ) can be coupled to the reference points 17.1 (e.g. by means of plug-in coupling bolts, which couple tolerance-free to the corresponding coupling points 45 of the support and movement devices 40a, 40b).
the reference points 17.1 are preferably formed as part of the manufacturing process of the side walls 17a, 17b on the corresponding structural section, in particular in at least one-layer flat material, preferably by laser cutting, whereby thanks to a comparatively high level of accuracy (in particular in the case of partially or fully automated material processing processes in the plane, e.g.
tiltable storage or suspension/mounting of the longitudinal section modules 11 also ensures a comparatively exact alignment of the longitudinal section modules 11 relative to one another, in particular in connection with the pairwise connection/marriage of the modules to one another (if their abutment planes are aligned parallel to one another, in particular in each case in a connection plane predefined by a module connection process arrangement with at least approximately vertical alignment), which also noticeably facilitates the use of the sheet metal connections described here in combination with, for example, essentially manually introduced force-locking/positive-locking connecting means 37 (in particular locking ring bolts) and the feasibility of the modular concept described here can be further improved.
the form-fitting contours described here also facilitate the arrangement of the corresponding material sections on a work table unit for the production of the side walls or the side wall units or the supporting structure of individual longitudinal sections or modules.
a (load-)bearing module connection 30 is preferably provided, each comprising several sheet metal connections 31 with sheet metal angle units or plate units.
the respective sheet metal connections 31 are preferably based on purely force-locking/positive connection technology, whereby the resulting Holding force is preferably a frictional force, i.e. can be ensured without a positive connection.
the respective metal sheet connection 31 can comprise individual ones of the following connection components depending on the connection position: butt plate 31.1, inner angle or plate 31a (in particular curved angle piece), angle/angle piece 31b (in particular in a curved design), counter plate 32.
connection components are connected to one another in a positive/non-positive manner by means of connecting means 37 (in particular screw connection or rivet connection), in particular such that the supporting structures of the adjacent longitudinal section modules are held together in a frictional manner.
connecting means 37 in particular screw connection or rivet connection
fastening axes 34; 34.1, 34.2, 34.3, 34.4, 34.5, 34.6, 34.7, 34.8 are provided, which are defined by the sheet metal connection and the supporting structure, in particular by several (through) holes or optionally at least partially also fastening holes 35 designed as elongated holes (in particular oversized in the axial longitudinal direction for the purpose of position adjustment).
Screws and/or rivets for example in the form of locking ring bolts 37.1 are suitable as connecting means 37, whereby a lock nut 37.3 or a similarly acting counterpart (e.g. sleeve of a locking ring bolt connection) is also preferably provided.
a longitudinal section module connection arrangement 40 (or module connection process arrangement) enables the individual longitudinal section modules to be connected/married, whereby the handling and relative positioning can be carried out in an advantageous manner.
the respective longitudinal section module can be supported against the ground by means of support and movement devices 40a, 40b or correspondingly acting supports (assembly aids) (in particular first and second support and movement devices 40a, 40b for each longitudinal section module), whereby a lifting or tilting kinematics 41 can also be integrated into the individual support and movement devices;
a tilting device 42 enables a movement in the form of a tilting about a transverse axis for positioning a/the desired longitudinal section, for example for aligning a respective platform section in an inclined position in order to be able to position the corresponding inclined section in a horizontal alignment on the adjacent intermediate module.
the support and movement devices 40a, 40b can be mounted on wheels or rollers 43.
the support and movement devices 40a, 40b can preferably also each comprise side support units 44, by means of which the respective module can be supported via reference recesses made in the side wall units and positioned with minimal tolerances.
coupling points 45 arranged in a predefined manner with high precision can be provided on the side support unit 44, to which coupling units 46 (eg plug-in coupling bolts) can be coupled.
assembly line 100 can comprise further positioning units 50 (in particular equipped with guides or plug connections 53 on alignment plates), with the respective side support unit 44 preferably coupling in a standardized manner with a/the correspondingly provided positioning unit 50.
the side support units 44 can optionally be designed as comparatively slim side arm levers (e.g. also individually for each type of guideway device), and the positioning units 50 can e.g. be provided as largely standardized assembly aids by means of which the support on the ground is carried out. This further reduces the effort for any desired type-specific adaptation of assembly aids.
the longitudinal section module connection arrangement 40 is preferably provided as a component of an assembly line 100 for assembling support structures of modularly constructed guideway devices (in particular process/production line), namely in the end region of this assembly line 100, on which the individual longitudinal section modules are preferably already arranged and supported in a phase of module-specific assembly in the intended order and optionally also in an alignment coordinated for the connection.
the assembly line 100 can also comprise one or more alignment devices 101 (e.g.
a clamp (clamp connection) enables individual assembly aids to be held/fixed temporarily.
the assembly line 100 also includes a spatially planned cavity or an assembly clearance 110 below the alignment/support level of the respective intermediate module, in particular a clearance below the floor level, so that the intermediate modules can also be advantageously arranged flat above the floor when aligned horizontally (both for the module-specific assembly and for completing the entire support structure by connecting/marrying the individual modules).
connection plane is to be understood as an end side defined at least by the ends of the supporting structure of the respective module, on/in which a connection is provided in an abutting arrangement with the adjacent module, and the "connection plane” is to be understood in a narrower sense, also in a mathematical/geometric sense, as a plane in which the respective applied connecting means should be arranged or at least act.
several connecting means can be provided which are arranged axially overlapping the joint plane(s) in several connecting planes, e.g. parallel and/or orthogonal to one another, or which act in each case there.
step S1 The material intended for the creation of the support structure, in particular in the form of a flat material, is subjected to material processing (step S1 ) comprising a material recess, in particular by laser cutting; this processing step is preferably carried out with the flat material arranged on a work table. In this way, in particular the essential sections of the respective side wall (unit) can also be created.
step S2 a material-locking connection
step S2 in particular welding with a comparable arrangement of the flat material (on a/the same) work table.
butt welding can also be carried out in the area of the kink, in particular after the corresponding adjacent longitudinal sections of the head module in question have been positively positioned relative to one another on correspondingly introduced form-fitting contours.
a module-specific assembly (step S3 ) of at least the most important supporting structure components can then be carried out, optionally in the same plane or on the work table (or in its extension) that was used for steps S1 and/or S2. This is followed preferably by arranging and aligning (or relative positioning) several modules (step S4 ) in such a way that the modules can remain in the selected relative arrangement to one another in the further course of the production process, i.e.
module-specific handling and module-specific assembly (step S5) of, for example, built-in components can be provided, with the respective module being advantageously aligned, in particular in a horizontal plane (head modules with their platform section in horizontal alignment).
a preferably form-fitting/non-positive connection of several modules can then take place to form the supporting structure of the entire guideway device, with the head modules preferably only being tilted about a reference axis for this purpose in order to align the inclined section of the respective head module in a/the horizontal plane in which the intermediate module is/remains preferably arranged.
the guideway device can then be completed (step S7), e.g. by further assembly measures, for example relating to the balustrade or completing the peripheral drive or handrail components or installing the steps (the latter can optionally also be done on a module-specific basis).
Steps S4 to S6 and optionally also S7 are preferably carried out in the same assembly line, i.e. with the order of the individual modules unchanged and with aligned alignment in the longitudinal direction of the assembly line.
steps S4 to S6 reference is preferably made to reference recesses provided integrally in the respective module-specific support structure, with these reference recesses preferably being introduced in step S1 in a module-specific manner.
Fig.1 A conventional orientation of an escalator 3 in the manner of a lying Z-letter is illustrated. In this orientation, however, many assembly and handling processes are disadvantageously complicated.
the two head modules 11a, 11b of a modularly available guideway device are shown in an arrangement resting on support and movement devices 40a, 40b and with the respective platform section 11.1 in at least approximately, preferably exactly horizontal alignment (horizontal plane Exy).
horizontal plane Exy horizontal alignment
the installation of drive components or other installation components is also considerably easier.
Fig.3 illustrates, among other things, the process-related advantage associated with the present invention of an advantageous arrangement/alignment of the individual modules on the one hand in a phase of module-specific assembly/mounting, on the other hand also already in/for an assembly line 100 for the assembly of the entire support structure or the complete Guideway device.
the individual modules are still accessible from the front and advantageously aligned (in particular exactly horizontally), nevertheless the modules can be brought into a final relative position by a comparatively slim process by a comparatively short/small translation movement (x) and by tilting (head modules), in particular about the reference axes (y) provided integrally by the side wall units described here, and can be positioned/held there comparatively exactly (as e.g. in the Fig.6 shown relative position).
Fig. 4A, 4B, 4C further details of the supporting structure 15 of the respective module 11a, 11b, 11c are shown.
the structural features are already described in detail elsewhere; in this respect, no further details can be given with regard to the Figures 4
the metal sheet connections 31 described here are preferably provided on each joint plane of adjacent modules at least on the upper and lower flanges (on both sides in both side wall units) in several fastening/effective planes and are advantageously applied by means of locking ring bolts with integrated visual inspection (e.g. material lifting) with regard to end position or torque or effective preload around the fastening axis.
the sheet metal connections 31 described here in the respective section of the supporting structure preferably act in at least two connection planes E18, wherein the relative position of the individual fastening holes for the positive/positive connection means 37 can be specified by reference to the individual (or one of the) reference points 17.1, in particular in a laser cutting process; the fastening holes 35 ( Fig.10 ) can be laser cut (or introduced by the same material recessing process by which the reference recesses 17.3 are also introduced).
the respective side wall is optionally designed completely as a flat material section with recesses made in it (e.g. laser-cut recesses that result in an X-arrangement of diagonal strut sections, e.g. laser-cut X-contour), or has diagonal struts designed as welded profiles (in particular folded U-profiles), which interact with the flat material or are integrated into the structure via flat material sections.
recesses e.g. laser-cut recesses that result in an X-arrangement of diagonal strut sections, e.g. laser-cut X-contour
diagonal struts designed as welded profiles in particular folded U-profiles
FIG.6 individual modules 11a, 11b, 11c, 11c' of a guideway device 10 are shown in a phase of the assembly process in which the adjacent and to be connected joint planes are already aligned parallel to one another, in particular in that the head modules 11a, 11b are/were tilted about the reference axes provided integrally by the side wall units of the respective module and supported on the support and movement devices 40a, 40b, optionally using a lifting/tilting kinematics 41, which can be activated or operated, for example, by means of a tilting device 42 provided on the respective support and movement device.
a hoist can also be provided, depending on the equipment of a machine hall.
handling can also be ensured by means of the tilting device(s) 42 indicated here, even without a crane or load transfer means arranged above the modules; This also increases variability/flexibility and occupational safety, thus also reducing the safety requirements placed on the process.
the support and movement devices described here by means of which the individual modules can be arranged, positioned and aligned, can also be provided by so-called trolleys or trolleys, which are available in many machine halls or production facilities, especially if the trolleys or trolleys have an integrated height and/or lateral adjustment. It has therefore been shown that the positioning accuracy described here cannot necessarily be achieved solely by means of the reference hole grid described here in predefined/standardized positioning means (compare the disclosure of the positioning units equipped in particular with standardized guides or plug connections on alignment plates), but also by means of comparatively simply designed trolleys or trolleys, which can be used, for example, in conjunction with a traverse tree placed on them.
the respective truss tree is provided by two L-angles made of 8mm sheet steel that are welded together (in particular for a/the respective upper head module), whereby laser-cut reference recesses or corresponding coupling holes can be provided/introduced in the L-angles.
the respective lower head module and the respective intermediate module are, for example, mounted on U-profiles made of 8mm laser-cut sheet metal, which form a/the traverse tree.
Flat iron can be welded onto one of the L-angles or onto the respective U-profile.
the traverse trees described here as double L-angles or as U-profiles, preferably made of 8mm sheet steel (laser-cut), can each be arranged and secured on the respective support and movement device using angles and supports (in this respect, the positioning units described here can be characterized by these features). For example, one angle is screwed onto a support so that slipping out can be prevented.
A/the respective side support unit can also be provided by a preferably laser-cut and welded L-angle made of 8mm sheet metal, which can be screwed to the respective traverse tree.
the through bolts described here can also be applied to side support units designed in this way in conjunction with the relative positioning by using the reference recesses in the respective side wall.
an absolute (lateral) position reference particularly in the transverse direction, can also be provided, for example, by a tree (beam, vertical support) or point in a/the machine hall (e.g. also door frame), from which a geometric definition of at least individual sections of the assembly line can be specified, e.g. using at least one dimensionally stable profile (e.g. L-profile) which is fixed to the floor in a strictly axial alignment (or a differently defined fixed bearing side, compare the disclosure on the optionally usable side stop), if necessary also using optical assembly aids such as a laser beam or a flat laser beam plane.

a geometric definition of at least individual sections of the assembly line can be specified, e.g. using at least one dimensionally stable profile (e.g. L-profile) which is fixed to the floor in a strictly axial alignment (or a differently defined fixed bearing side, compare the disclosure on the optionally usable side stop),
step S1 material processing
step S2 material-locking connection
step S3 material-specific assembly of at least the most important support structure components (side wall units or at least side walls and crossbars) can then already take place.
step S4 This is followed by an arrangement and alignment (or relative positioning) of several modules (step S4 ) in such a way that the modules can remain in the selected relative arrangement to one another in the further course of the creation process, in particular with the intermediate module and the respective platform section in an exactly horizontal Alignment.
module-specific handling and module-specific assembly step S5 ) of, for example, built-in components can first be provided; in particular, drive components and guide rails are assembled.
a preferably form-fitting/non-positive connection of several modules can then take place to form the support structure of the entire guideway device, wherein the head modules are preferably only tilted about a/the corresponding reference axis for this purpose, in order to align the joint plane of the respective module, in particular in an at least approximately vertical connection plane.
the form-fitting/non-positive connection can be carried out using optionally pre-assembled sheet metal connections, in particular in the area of the respective upper/lower chord.
the sheet metal connections 31 comprise the joint tabs, counter plates and angle pieces described here and are preferably fixed manually using locking ring bolts in numerous fastening axes in several connection planes, wherein the relative position can optionally be adjusted on at least some of the fastening axes (in particular thanks to the elongated holes provided there).
the guideway device can then be completed (step S7 ), for example by further assembly measures, for example concerning the balustrade or a completion of circumferential drive or handrail components or an installation of the steps.
Step S6 is preferably carried out in a/the longitudinal section module connection arrangement 40, which is preferably set up to position the individual modules without support arms or other assembly aids that hold/grip from above, i.e. solely supported on the ground.
Steps S4 to S6 are preferably carried out in the same assembly line, with the order of the individual modules unchanged and with aligned alignment in the longitudinal direction of the assembly line, with reference being made to the reference recesses provided integrally in the respective module-specific support structure during alignment, support and positioning.
Fig. 8A, 8B details of a metal sheet connection 31 provided on the upper chord are shown; four fastening axes 34.1, 34.2, 34.3, 34.4; 34.5, 34.6, 34.7, 34.8 are provided for each fastening level, which are arranged two-dimensionally offset in at least one of the fastening levels.
the internal connecting means (with their heads in an arrangement within the created square profile) can be pre-assembled on the lower of the L-profile sections brought into contact with one another (or the L-profile sections resting on the side wall from the inside), and the Fig. 8A visible connecting elements 37 are/remain accessible from the outside (laterally).
Fig. 8B it is clear that four flat material sections can be connected to one another in a force-fitting manner by means of the respective metal sheet connection 31, namely two flat material sections per module, in particular each provided as L-profile sections.
This design makes it possible to provide the profile sections made of bent flat material integrally with other support structure sections (in particular the side wall) and advantageously to provide a cross-sectional profile with a high load-bearing capacity (in particular also a high bending moment), in particular when the L-profile sections come into contact with one another in a form-fitting manner in slots and otherwise a gap is left.
a material-fitting connection can optionally also be realized (locally), in particular a weld seam.
the profile sections 16.1a can be provided, for example, as L-profile sections, which together with a corresponding asymmetrically designed L-profile section of the side wall structure result in a type of square profile, in particular by connecting these L-profiles to one another at least at certain points or in linear/slot-shaped sections, in particular by means of a material bond (e.g. by welding).
This also makes it possible to realize a cross-sectional geometry for the respective upper and lower chords that can be easily customized, with comparatively high accuracy.
the corresponding slots or recesses for the L-profile sections to fit together in a form-fitting manner can also be introduced into the flat material with reference to the reference points described here, in particular by laser cutting.
Individual profile sections can optionally also be designed in a U-shape.
a load-bearing module connection 30 which comprises a metal sheet connection 31 on the upper belt 17.7 and lower belt 17.9, each of which is formed from an angle piece and a counter plate and eight connecting elements each.
the connecting means 37 aligned at least approximately in the vertical direction or orthogonally to the longitudinal direction of the support structure can be pre-assembled, and the other connecting means that act in the transverse direction are still accessible from the outside (independently) of the assembly phase.
the angle piece 31a is preferably used for the referenced positioning of the longitudinal sections or the support structure sections to be connected to one another.
Fig.10 details of a metal sheet connection 31 provided on the lower chord 17.9 are shown.
the L-angles shown can also be designed as individual plates, at least partially.
At least some of the fastening holes 35 can be designed as elongated holes.
the individual components of the respective sheet metal connection 31, in particular the angle pieces 31a, 31b, can also be used as referencing means for positioning the modules relative to one another.
the Fig.10 illustrated contact force F for (at least essentially) force/frictional engagement on the superimposed contact surfaces of the corresponding flat material section of the supporting structure on the one hand and the butt plate or the angle piece or the counter plate of the sheet metal connection on the other hand.
a gap 18.2 is also visible, which can be realized between adjacent L-profile sections 16.1a arranged relative to one another to form a square cross-sectional profile, so that the module connection provided can act purely force-fitting and certain tolerances and positional deviations do not lead to warping or wedging of the longitudinal section modules that are connected to one another; this has a positive effect on the operating behavior and service life, not least with regard to long-term dynamic stress on the entire support structure.
this relative positioning with a gap also enables easier diagnosis and maintenance, particularly in connection with surface sealing/preservation and material fatigue aspects.
