Definitions

  • the invention relates to a multi-part connection device for a safety device of a ceiling formwork system for producing a ceiling or a ceiling section in concrete construction.
  • the invention relates to a ceiling formwork system for producing a ceiling or a ceiling section in concrete construction with such a connection device.
  • a use of the multi-part connection device in a ceiling formwork system is also proposed.
  • Slab formwork systems include formwork panels that are laid next to each other in one level to form a level ceiling soffit. The installation is carried out on girders running parallel to each other, which in turn rest on ceiling supports. When laying, the formwork panels can be lifted in from below or placed on top. At least one person must stand on the supporting structure or on a formwork panel that has already been laid in order to place the formwork panels on from above. This person can fall into a space left between two beams and fall. So that this does not happen, the distance between the carriers can be chosen to be correspondingly narrow. Alternatively, a collecting device, for example in the form of a net or grid, can be provided in the free space. The fall arrester and the connection of the fall arrester to the slab formwork system must be such that it can withstand the load of a person falling into it. The load must also not lead to the slab formwork system collapsing.
  • CGS:SZ A fall protection system for ceiling formwork is known from WO 2019/069246 A1, which comprises spacer elements and a net that can be attached thereto.
  • the spacer elements are arranged at a distance from one another, in each case transversely to two parallel beams, so that the spacer elements span the free space between the two beams.
  • the spacer elements each have a bar element with bearing elements arranged at the ends. Holding elements for fastening the net are arranged on the bearing elements.
  • WO 2019/069246 A1 reveals in particular two types of bearing elements for a spacer element.
  • a first type is placed or plugged onto a carrier from above, so that the formwork panels no longer come to rest directly on the carriers, but on the bearing elements resting thereon. This must be taken into account when setting the altitude. Since a bearing element resting on or attached to the carrier remains displaceable relative to the carrier, fixing by means of additional fixing means, for example in the form of nails, is recommended to secure the position.
  • additional fixing means for example in the form of nails.
  • the use of nails makes sense, since in WO 2019/069246 A1 yokes are used as supports.
  • the additional fixing with the help of nails makes it more difficult to dismantle the ceiling formwork system after the ceiling or the ceiling section has been completed.
  • a second type has a base plate with a central linkage bushing.
  • the bearing element is placed on a ceiling support via the base plate and fixed in position with the aid of a rod stub reaching through the rod bushing.
  • the rod stub is preferably arranged on a fork element, which serves to accommodate a yoke and is connected to the ceiling support via the rod stub.
  • the base plate of the bearing element thus comes to rest between the floor prop and the fork element, so that the bearing element also influences the height of the formwork panels here.
  • the present invention is concerned with the task of simplifying the assembly and/or disassembly of a safety device, in particular a collecting device, of a ceiling formwork system.
  • a safety device in particular a collecting device
  • the connection of the safety device to the ceiling system should enable safe load transfer via the ceiling system in the event of a load.
  • connection device with the features of claim 1 and the ceiling formwork system with the features of claim 13 are proposed.
  • Advantageous developments of the invention are the respective to be found in the subclaims.
  • a use of a connection device in a ceiling formwork system is also specified.
  • a multi-part connection device for a safety device of a ceiling formwork system for the production of a ceiling or a ceiling section in concrete construction which comprises a base part with at least one plug-in pin extending away from the base part and a plug-on part with at least one recess for receiving the plug-in pin of the base part.
  • the slip-on part has a first end section for connection to the safety device, preferably to a linkage of the safety device, and a second end section with means for connection to a carrier of the ceiling formwork system.
  • the plug-on part of the multi-part connection device can therefore be connected indirectly via the base part and directly to the ceiling formwork system. In this way, a double and thus reliable positional securing of the connection device or the securing device can be effected. At least the possibilities for this are created.
  • the means provided on the second end section of the plug-on part for connection to a support of the ceiling formwork system are preferably designed in such a way that a connection securing the position of the plug-on part is only established in the event of a load or when the safety device is loaded. If the load case does not occur, only the indirect connection made via the base part has to be loosened when dismantling the safety device. The safety device can thus be dismantled quickly and easily. This applies in particular if the base part is also only connected to the ceiling formwork system via a plug-in connection.
  • the means provided on the second end section of the push-on part for connection to the support cause a non-positive, frictional or positive connection between the push-on part and the support when the securing device is loaded.
  • the non-positive, frictional or positive connection is intended to prevent a change in position, in particular a displacement, of the attachment part relative to the carrier, so that the attachment part is additionally secured in position.
  • the additional position security increases the resilience of the security device.
  • a collapse of the safety device under load can be counteracted since horizontal forces are absorbed by the carrier or the carriers, so that the safety device remains open under load.
  • Horizontal forces acting transversely to the beams are preferably the linkage of the safety device was added. Tilting of the carrier can thus be counteracted with the help of the linkage.
  • the means provided on the second end section of the push-on part for connection to the carrier have at least one projection that can be brought into engagement with the carrier, for example in the form of a tooth, a dome and/or a tip.
  • the at least one projection provided on the attachment part is oriented in such a way that it automatically digs into the carrier when the safety device is loaded. If the load does not occur, the projection remains on the outside of the carrier, preferably in the area of a lower chord of the carrier.
  • the plug-on part is connected to the girder in the area of a lower chord, the height of the formwork panels remains unaffected. These can also be placed directly on the carrier, in particular on an upper belt of the carrier.
  • the carrier is preferably at least partially made of wood or a wood-based material.
  • the at least one projection provided on the second end section of the push-on part can dig into the carrier particularly easily.
  • the carrier can be made at least partially of aluminum or plastic, since these materials also allow the at least one projection to dig in when the safety device is loaded.
  • the carrier preferably has an upper chord and a lower chord, which are connected via a web. To reduce the weight, the web can be formed by individual rods, so that the carrier is constructed in the manner of a lattice girder.
  • the lower chord of the girder is preferably made of wood, a wood material, aluminum or plastic, since the second end section of the attachment part is preferably placed on the lower chord of the girder so as not to influence the height of the formwork panels.
  • the attachment part is preferably placed on the lower chord of the carrier in such a way that the attachment part is supported by the at least one projection on the lower chord. Under load, the projection then digs into the bottom flange of the beam.
  • the push-on part is tubular at least in sections and/or is made from a piece of tubing. The tubular design leads to high mechanical strength with low weight at the same time. The low weight facilitates the assembly and disassembly of the connection device. At the same time it is ensured that the connection device withstands high loads.
  • the second end section of the push-on part is tubular or is made from a piece of pipe, this can be cut out in the area of the second end section to form the at least one projection over a partial peripheral area.
  • the at least one projection is formed by the piece of pipe itself, so that it can be produced comparatively easily and inexpensively.
  • the cutout can extend in the circumferential direction over an angular range of 100° to 180°. From there, the cutting line can run parallel to the longitudinal axis of the pipe section on both sides of the pipe section in the direction of the pipe end. By bending the cutting line just before the end of the tube, a pointed projection can be formed on both sides of the tube piece.
  • Projections formed in this way are oriented essentially perpendicularly to the longitudinal axis of the pipe piece.
  • the piece of pipe can accordingly be placed on a lower chord of a carrier in such a way that it is vertically supported by the projections on the lower chord. In the event of a load, the projections then dig themselves automatically into the bottom flange of the beam.
  • At least the first end section of the attachment part is tubular or made from a piece of pipe, a simple connection, in particular plug-in connection, can be established with a linkage of the safety device via the tubular end section of the attachment part.
  • At least the first end section of the push-on part is therefore preferably of tubular design.
  • the plug connection that can be produced here can be easily assembled and disassembled.
  • the plug-on part has at least one casing-side or lateral opening for receiving a socket pin.
  • the plug connection can be locked with the aid of the socket pin.
  • the plug-on part preferably has a hook-like or eyelet-like receptacle for a net or grid of the safety device on the casing side or on the side.
  • the hook or loop-like recording is designed such that the network or Grid can be easily hung directly or indirectly, for example using a snap hook. In this case, the connection can be easily released again when the safety device is later dismantled.
  • the distance (a) between the two spigots for accommodating the attachment parts must be at least the width of the carrier or greater than the width of the carrier so that the two spigots come to rest on both sides of the carrier. If the plug-on parts are then placed on the plug-in pins, the "second" end sections of the plug-on parts should come to rest on the lower flange of the carrier on both sides of the carrier, so that they are vertically supported by the means for connecting to the carrier. If the load occurs, the means for connection preferably automatically penetrate into the bottom flange of the beam.
  • a fork element usually has four prongs that are connected via a common, usually rectangular base plate.
  • the fork element On the side facing away from the tines, the fork element has means for producing a plug-in connection with a ceiling support.
  • the angular position of the fork element can be changed in such a way that the distances between the Prongs vary with each other. In a first angular position, the fork element can thus accommodate one carrier and, in a second angular position, two carriers next to one another.
  • the base part of the proposed connection direction can preferably be inserted into the fork element in any angular position of the latter. To accommodate one beam or two beams, you only need to change the orientation of the base part.
  • the cutout provided in at least one corner area of the base part preferably has an undercut area, so that a prong of a fork element accommodated in the cutout is gripped behind by the base part. In this way, a positive fit is achieved between the base part and the fork element, which prevents a base part that has already been attached to the fork element from falling down during assembly.
  • the base part has a base plate with at least four plug-in pegs which are arranged in pairs at a distance (a) opposite one another on the base plate and extend in a first direction, preferably perpendicular to the base plate.
  • the two plug-in pins, each arranged on the same side, are used to connect to a plug-on part, so that a total of two plug-on parts can be connected to the base part.
  • the plug-on parts are each arranged between two plug-in pins, so that they come to lie on both sides of the plug-on part in a corresponding recess of the plug-on part.
  • the plug-on part has at least two recesses on the casing side for receiving the plug-in pins.
  • four further plug-in pins are located opposite one another in pairs at a distance (b) on the base plate and extend in a second direction, preferably perpendicular to the base plate.
  • the distance (b) is preferably selected to be greater than the distance (a).
  • the plug-on part has two recesses for receiving two plug-in pins of the base part.
  • the two recesses are preferably arranged on opposite sides of the attachment part, so that the plug-in pins come to lie on both sides of the attachment part or engage in the attachment part. In this way, a form-fitting connection is achieved between the attachment part and the base part, which--particularly under load--prevents the connection from being unintentionally released.
  • the two recesses are preferably designed in the form of slots, so that the plug-on part can be plugged onto the two plug-in pins from above,
  • the recesses provided in the longitudinal side of the strip each have an undercut area for the positive connection with the fork element, in particular with the prongs of the fork element.
  • the form fit is intended to prevent a shift, in particular a horizontal shift, of the bar relative to the fork element, so that the bar cannot be pulled out to the side.
  • the strip can only be attached to the prongs from above.
  • the shape of the undercut area of a recess is preferably adapted to the cross-sectional shape of the prong to be accommodated. This can, for example, have an angular cross section with a flattening in the corner area. The bar can then be attached to the fork element in such a way that the bar engages behind the flattened area of a prong.
  • connection device is preferably used in a ceiling formwork system for producing a ceiling or a ceiling section in concrete construction, such a ceiling formwork system is also proposed.
  • This includes a fork element that can be connected to a ceiling support, a carrier that can be inserted into the fork element, and at least one connection device according to the invention for connecting a safety device.
  • the fork member preferably has a rectangular base with four upstanding prongs located in the corners of the base so that the spacing of the prongs varies and one or two carriers can be inserted into the fork member.
  • the carrier preferably has an upper chord, a lower chord and a web connecting the upper chord to the lower chord.
  • the web can also be formed by individual rods, so that the carrier is constructed in the manner of a lattice girder.
  • the carrier is at least partially made of wood or a wood material.
  • at least the bottom chord of the carrier is made of wood or a wood-based material, since this material easily enables a form-fitting connection with the connection means provided on the second end section of the push-on part.
  • the carrier is a yoke.
  • the base part of the connection device can preferably be plugged or plugged onto the fork element, so that the base part is arranged under or next to the carrier in the position of use.
  • the arrangement of the base part depends on the specific design of the base part, in particular whether the base part comprises a base plate or a strip which can be plugged or plugged onto the fork element.
  • the base plate preferably receives all four prongs of the fork member so that the base is centered with respect to the fork member and underlies the bracket.
  • the strip preferably only accommodates two of the four prongs, so that it lies laterally next to the carrier and does not affect the carrier construction dimension.
  • the at least one plug-in pin of the base part preferably extends vertically or approximately vertically upwards.
  • the plug-on part of the connection device can preferably be plugged onto the plug-in pin or plug-in pins of the base part, so that when the plug-on part is in the position of use, the at least one self-locking projection in the form of a tooth, dome and/or a point is on the carrier, preferably on a lower belt of the carrier rests.
  • the plug-on part is attached to the spigot or pegs of the base part from above, so that the plug-on part is supported by the at least one projection in the vertical direction on the carrier, in particular on the lower chord of the carrier.
  • the plug-in pin accommodated in the plug-on part or the plug-in pins accommodated in the plug-on part prevent/prevent the plug-on part from slipping sideways.
  • the free end of the plug-on part can be connected to the safety device, in particular to a linkage of the safety device. This connection is preferably also a plug-in connection in order to facilitate assembly and disassembly of the safety device.
