Definitions

  • the invention relates to a lamella transition for expansion joints on bridges or the like, which consists of parallel to the expansion joint, slidably supported on the joint edges and slidably supported cross members with a device for distance control, whereby at the joint edges provided with an edge lamella U -shaped bearing frame for the cross member and rectangular bearing frames are attached under the slats, the cross member comprising, in which the cross members are braced vertically against an elastomeric plain bearing.
  • lamella transition brackets are mounted on the edge rails of the expansion joint on which the elastomeric plain bearings are fastened to support the cross members.
  • the crossbeams are braced on the brackets with threaded bolts that are attached to the associated edge rail above the bracket and can be screwed downwards against the upper flange of the crossbeam.
  • support plates for slide bearings lying against the sides of the crossbeams are attached to the brackets.
  • the lamellae are supported by rectangular bearing frames attached under the lamellae, with elastomeric pot bearings provided on the bottom and the two inner sides, which are also clamped with screw elements are.
  • the arrangement of the bearing frame under the lower flange of the lamellae has the disadvantage that the lamellae are exposed to large tilting moments when exposed to the traffic loads, and this makes their distance control considerably more difficult or even impossible.
  • DE-PS 30 19 594 an embodiment is known in which the cross beams protrude through openings in the slats, so that the tilting moments are relatively low; the distance control used in this version by linking the slats with partial cross members is complex and also very susceptible to failure due to the stress on the elastomeric bearing bodies due to thrust and torsion.
  • the distance control described in DE-AS 27 46 490 provides a sliding pivot bearing of the slats on the transverse bearings arranged in alternating directions, so that the slats are moved in the manner of a scissor lattice when the joint width is changed by pivoting the transverse bearings; this version is very complicated and extremely susceptible to tipping and tilting of the slats.
  • the elastic control proposed by DE-AS 16 58 611 with the aid of elastic control springs arranged between the lamellae and inclined cross members, a different distance between the lamellae can arise as a result of braking.
  • the slats are each connected to the adjacent slats or edge slats by handlebar pairs, each handlebar pair being provided with a return spring and each handlebar rod engaging in a longitudinal slot of the adjacent slats or edge slats.
  • the traffic loads are disadvantageously transferred directly to the handlebars.
  • a trailing sheet construction in which on one side a gap bridge covering the gap and arranged on the other side is an expansion device which fills a joint formed on the connecting structure between the front end of the split bridge and the adjoining roadway.
  • the stretching device consists of wide-flange beams running along the web direction, which are arranged in a fixed position and on which slats are slidably mounted.
  • the lamellae are provided with claws which reach under the flanges of the wide-flange girders and which should result in resilient mounting.
  • the control of the slats is a scissor construction, one end of which is pivotally mounted on the connecting structure in the vicinity of the carriageway and one slat is articulated to the cross bearings.
  • This stretching device and the slats controlled by it do not allow any immediate bridging of the gap in their arrangement and storage.
  • the object of the invention is to provide a lamella transition corresponding to the generic name for expansion joints on bridges or the like with a suitable device for distance control.
  • the components associated with the lamella transition should be adapted as best as possible to the distance control.
  • the control scissors ensure simple and very wear-resistant distance control of the slats. It is acted upon by the control forces, which act directly on each slat. In contrast, the vertical traffic loads are transferred from the slats to the joint edges via the cross beams.
  • the separation of the one Devices for load transmission from the device for distance control has the advantage that both systems can be optimally designed for their function, but also easier replacement of wearing parts is possible.
  • the rectangular bearing frames assigned to the slats are expediently installed in a cutout of the slats that extends approximately below the upper profile edge. This considerably relieves the bearing on the control scissors on the slats, and the control scissors are practically not exposed to bending and shear stresses due to traffic loads.
  • a tensioning body rests elastically against the crossbeam in the bearing frame of the joint edges and the lamellas.
  • the cross member is pressed elastically downwards onto its elastomeric plain bearings, and, on the other hand, the lamellae with their elastomeric plain bearings are pressed down against the upper flange of the cross members. This not only prevents rattling noises from traffic, but also better compensates for any tilting movements of the slats and the cross members.
  • bearing journals are expediently arranged under the lamellae and edge lamellae. So that any tilting movements of the lamellae are not transmitted to the control shears, an elastic bearing ring is arranged between the bearing journal and the bearing bush of the cross bearing. This storage absorbs any vertical and horizontal force components, so that shock loads on the lamella len practically not be transferred to the control scissors.
  • the clamping bodies can consist of an elastic rubber or plastic, which can be compressed to a certain extent. These clamping bodies not only generate the preload force, but also significantly simplify the assembly of the lamella transition and the replacement of wear-bearing bearings and the clamping body itself. Thus, by simply lifting the crossbeams, the upper elastic clamping bodies are pressed into the U-shaped bearing frame and the lower elastomeric plain bearings are exposed for replacement. Once these elastomeric plain bearings have been removed, the cross members can also be placed on the bare U-shaped frame and the upper clamping bodies can be replaced. The upper elastomeric plain bearings and the lower clamping bodies can be exchanged in a corresponding manner in the rectangular bearing frame associated with the lamellae.
  • the lamella transition shown in FIG. 1 serves to bridge an expansion joint which is formed between the joint edges 1 of a bridge and connecting structure or the like.
  • An edge rail 2 is attached to each of the two joint edges 1, on which several cross members 3 bridging the expansion joint are slidably and tiltably mounted.
  • On the cross members 3 slats 4 are slidably mounted along the expansion joint.
  • On the edge rails 2, an edge plate 5 corresponding to the plates 4 is fastened.
  • the two edge rails 2 and edge lamellae 5 are connected by control shears 6, on the cross bearings 32 of which the lamellae 4 are articulated.
  • These control scissors 6, which are designed in the manner of a Nuremberg pair of scissors, are arranged between the cross members 3.
  • a sealing profile 28 is inserted, which drains rainwater laterally to the edge of the road and protects the functional parts of the slat transition from dirt.
  • openings 7 are provided in the edge rails 2, through which the ends of the cross members 3 protrude into boxes 15.
  • Fig. 5 illustrates, welded to the edge rails 2 under the edge lamella 5 U-shaped bearing frame 8 through which the cross members 3 provided on their four sides with sliding layers 17 protrude and which absorb their forces.
  • elastomeric plain bearings 9 are provided, each of which projects into a bore 11 with a pin 10.
  • elastic clamping bodies 12 are attached to the two sides and above, which are also inserted with a pin 13 into a bore 14 of the bearing frame 8.
  • This clamping body 12 consist of an elastic rubber or plastic and are compressible to the extent that when lifting the cross member by means of a crane or the like.
  • the lower elastomeric plain bearings 9 are exposed for replacement.
  • the storage of the cross member 3 in the bearing frame 8 enables a perfect expansion compensation, the cross member 3 sliding into the bearing frame 8.
  • the storage also allows tilting of the cross member 3 when the bearing frame 8 on both sides of the joint at different heights, for. B. due to different vertical dimensions of the buildings concerned.
  • Rectangular bearing frames 18, which include the cross members 3, serve to support the slats 4 on the cross members 3.
  • the bearing frame 18, as shown in FIG. 6, is installed in cutouts 21 which extend into the web 20 to just below the upper profile edge 19 which serves to accommodate the sealing profiles 28.
  • the bearing frames 18 are each provided with an upper elastomeric sliding bearing 22, which engages with a pin 23 in a bore 24, and with a lower elastic clamping body 25, the pin 26 of which lies in a bore 27.
  • the lamellae 4 are tensioned downwards by the clamping bodies 25. Due to the high and relatively wide bearing surface, the slats 4 are very stable.
  • the wearing bearing parts namely the elastomeric sliding bearings 22 and the clamping bodies 25, can easily be replaced after the lamellae 4 have been raised. Since the plain bearings 9 and 22 and the clamping bodies 12 and 25 of the bearing frames 8 and 18 are of the same design, only two components are required for exchange purposes.
  • the control shears 6 provided for distance control are shown in FIGS. 3 and 4.
  • the two ends of the control scissors 6 are articulated on the two joint edges 1 below the associated edge blades 5.
  • a bearing block 30 is provided under the edge plates 5, in which a journal 31 z. B. is fastened by means of a grub screw or the like.
  • Corresponding bearing journals 31 are fastened in bearing blocks 33 under the lower chords 29 of the slats 4, onto which the cross bearings 32 of the control scissors 6 are attached.
  • a bearing bush 36 is fastened in each of the bores 35 of the cross bearing 32, and the bearing journals 31 are tapered downward and braced in the bearing bush 36 with an elastic bearing ring 37.
  • the elastic bearing rings 37 consist of elastomers or similar materials. All cross bearings 32 and end bearings 34 have play in the vertical direction, so that vertical force components are not, but the horizontal control forces are transmitted.
  • the side bearings 38 associated with the control scissors 6 are shown in FIGS. 1 and 4.
