Definitions

  • the invention relates to a joint bridging device for expansion joints in bridges or the like with one or more slats extending in the longitudinal direction of the joint gap, which are supported with respect to the joint edges.
  • the invention has for its object to provide a joint bridging device that requires only a few components, is characterized by a favorable distribution of the vertical loads, and in which the slats are controlled to achieve equal mutual distances and secured against tipping.
  • the lamellae are connected to each other and to the joint edges connecting cross members, each rigid with a lamella or a joint edge and connected to at least one adjacent lamella over-shear-deformable, elastomeric bearing body so that these form an elastic bearing chain running from one joint edge to the other and that the shear deformations caused by the opposing thrust forces in the bearing bodies are the same for each lamella.
  • the load distribution over the entire joint area is considerably improved over the known devices by the partial cross members;
  • Another major advantage is the tilt protection of the slats, which is achieved by the rigid connection of each slat with a partial crossbeam.
  • the tilting moments resulting from traffic loads are absorbed by vertical opposing forces in those lamellae which interact via a partial crossbar with the loaded lamella, which in turn is rigidly connected to the partial crossbar.
  • the load distribution mentioned above also takes place via the partial cross beams. In the case of short partial traverses, which have a joint edge with the adjacent lamella or two adjacent ones If the slats are connected to each other, the load is distributed through torsional stress on the slats.
  • the load is distributed by bending the partial crossbeams and corresponding vertical forces in the lamellas.
  • the last-mentioned embodiment with long partial cross members offers a particularly favorable load distribution with a high load-bearing capacity of the construction.
  • the elastomeric bearing bodies tolerate joint movements in any direction; an inclination or inclination of the joint edges is compensated for elastically, so that there are no constraints between the lamellas and partial cross members.
  • Another proposed solution for larger joints according to the invention in which the lamellas are supported on their ends by means of cross members which are displaceably mounted in the opposite joint edges, provides that in addition to the cross members load-distributing partial cross members are provided, each in openings of a joint edge and one or more Slats or in openings of at least two slats are received, with each slat at least two partial crossbars, one of which engages via a rigid connection, so that all slats are connected to one another and to the joint edges via a chain of partial crossbars.
  • crossbeam arrangements are possible in connection with this proposed solution.
  • the cross members are preferably each in at least vertically limited openings of all slats are smoothly added.
  • these are each rigidly connected to only one lamella, each lamella in turn being connected to at least two cross members.
  • the slats can either be made particularly slim or can be supported with a wide span, with no loss of safety against tipping.
  • the partial traverses can be accommodated in the openings of the slats in various ways.
  • One solution provides that the partial traverses are slidably received there, whereby they are each received between vertically prestressed elastic sliding bodies in the opening area.
  • Another solution provides that the partial traverses are firmly connected to the lamella or the joint edge in the opening area of at least one lamella or the joint edge via shear-deformable elastomeric bearing bodies;
  • two bearing bodies namely one each on the top and bottom of the partial cross member, can be provided in the opening area and prestressed in the vertical direction. The pretensioning of the bearing body or sliding body ensures that tilting moments and vertical loads are absorbed practically without play.
  • the alternative mounting via shear-deformable elastomeric bearing bodies brings with it the decisive advantage with joint bridging devices that Control of the lamellae in the joint area is achieved via the shear deformation of the elastomeric bearing body, such that the lamellae are always distributed uniformly over the joint width, that is to say they have the same distances from one another and from the joint edges.
  • the slats can consist of an upper chord and a lower chord, which are connected to one another via rigid webs;
  • beams with a lower overall height are also possible, on the underside of which U-shaped steel brackets or other brackets are welded, in the openings of which the cross members or cross beams are received.
  • the slats can be lengthways have continuous grooves in which the lateral connecting edges of the expansion profiles are clamped or buttoned.
  • the partial traverses are partly rigid, partly connected to the slats via shear-deformable elastomeric bearing bodies, in such a way that all the slats are supported with one another and with the joint edges via an uninterrupted chain of elastomeric bearing bodies.
  • the distance K indicates the circumference of the support elements belonging to such a chain.
  • FIGS. 2 and 3 show a construction with only one lamella L between the edge lamellae LR1 and LR2.
  • the lamella L is supported on sub-beams TK1, TK2, which are anchored in the manner of a bracket, as shown in section in FIGS. 2 and 3.
  • the lamella L is supported by elastomeric thrust-deformable bearing bodies 4, which are firmly connected on the one hand to the underside of the lamella L and on the other hand to the upper side of the partial crossbars TK1 and TK2.
  • niches 6 are provided in the joint edges, in each case opposite the partial crossbars TK1, TK2, which allow the partial entry of the free ends of the partial crossbars TK1, TK2 into the opposite joint edge.
  • the almost closed joint is shown in FIGS. 2a and 3a, the bearing bodies 4 being correspondingly shear-deformed.
  • the bearing bodies 4 are completely identical components that can be shear deformable in all lateral directions. The bearing body 4 therefore not only take over the center control of the lamella L; they also serve to compensate for longitudinal displacements of the joint edges, as shown in FIG. 4a, or also for warping of the joint edges in the vertical direction. 2, 3 and 4 each show the neutral joint position to the respective cuts, FIGS. 2a, 3a and 4a represent the respectively associated deflected joint positions.
  • FIG. 5 to 7 show a joint bridging device with two slats LA1 and LA2 between. between the lamellae LR1 and LR2.
  • the left lamella LA1 is supported on partial crossbars TK1 anchored in the left joint edge via bearing body 4; the right lamella LA2 is supported on the right cross member TK2 over bearing body 4.
  • short partial traverses TT1, TT2 are provided, which connect the two slats LA1 and LA2 to one another.
  • a number of partial cross beams TT1 is rigidly connected to the left lamella LA1 and an equal number of partial cross beams TT2 to the right lamella LA2.
  • the partial traverses TT1, TT2 are connected to the respective other lamella via bearing bodies 4.
  • the partial traverses are the same cher height with the edge-fixed partial crossbars TK1, TK2 (see Fig. 7 with Fig. 6) ..
  • the partial crossbar TT2 shown in Fig. 7 is at one end via a rigid support 7 with the underside of the right lamella LA2, with the other end connected to the left lamella LA1 via an elastomeric bearing body 4.
  • the one-sided rigid connection of the partial cross members ensures that the shear deformation of the bearing bodies connected to the short partial cross members TT1, TT2 is the same as the shear deformation of the bearing bodies connected to the console-like partial cross members TK1, TK2.
  • FIGS. 8 to 11 show a joint bridging device with three slats between the edge slats LR1 and LR2, namely a central slat LM and two outer slats LA1 and LA2.
  • the outer lamellae LA1 and LA2 are supported in the manner already described in relation to FIGS. 5 to 7, that is to say via console-like partial crossbars TK1, TK2 with respect to the adjacent joint edges.
  • the middle lamella LM is supported by a long partial crossbar TT3 connected to the outer lamellae LA1, LA2, which is rigidly connected to the underside of the middle lamella LM.
  • the partial cross beams TT3 are in the height of the console-like Partial traverses TK1, TK2 arranged, as a comparison of the sectional views according to FIGS. 9 and 10 shows.
  • the two outer plates LA1, LA2 are each supported on a partial crossbar TT3 by means of bearing bodies 4.
  • the ends of the partial crossbars TT3 are clamped to the underside of the lamellae by U-shaped bearing brackets 8, as shown in FIG. 11.
  • Another bearing body 4 is inserted between the bearing bracket and the underside of the partial cross members TT3.
  • the bearing brackets 8 are dimensioned such that the bearing bodies 4 which they each surround are pressed against the underside of the respective lamella or against the underside of the associated partial crossbeam under prestress.
  • the plan view of a length section of a joint bridging construction shown in FIG. 12 comprises four further slats L 1 - L 4 in the region of the joint gap between two edge slats LR1, LR2 anchored in the joint edges. All of the lamellae Ll - L4 are slidably supported within the length section shown on two cross members Q1, Q2, the sliding bodies 10 serving for the sliding bearing being indicated by circles with cross-hatching.
  • the crossbeams Q1, Q2 are each received with their two ends in corresponding recesses 9 of the joint edges and are also stored there between sliding bodies 10.
  • the cross member Q2 is through openings inserted in the slats L1 to L4 and in the edge slats LR1, LR2. In the opening area, the cross member is slidably mounted between an upper and a lower sliding body 10. Between the lamellae, elastomeric sealing profiles 5 sealingly connected are shown schematically on their inner sides.
  • the lamella profile is composed of an upper flange 19, a lower flange 20 and vertical webs 21 connecting both belts, e.g. in the form of a double T-profile.
  • the essentials of the construction acc. Fig. 12 is a chain of partial traverses T10 - T60, which are each connected to a joint edge and one or two slats or three slats, depending on the length and arrangement.
  • the hatched connection point means a rigid connection, for example in the manner of a welded connection.
  • the connection point indicated with a cross mark means that the partial cross members are clamped in the opening area of the lamellae between elastically prestressed bearing bodies 11 (FIGS. 15, 16).
  • the elastic bearing bodies 11 are designed in the manner of the sliding bodies 10 supporting the crossbeams, that is to say only connected to the slats, not also to the partial cross members; or the bearing bodies 11 are shear-deformable elestomeric bearing bodies, which are firmly connected both to the lamella, in its opening area, and to the partial cross member. When the joint width changes, such shear deformable bearing bodies 11 deform accordingly.
  • the left connection means a rigid connection of the lamella LR1 via connecting parts 12 in the opening area.
  • the right-hand connection of the partial crossbeam T10 shows two bearing bodies 11, between which the end of the support element T10 which engages in the opening area of the lamella L1 is movably received relative to the lamella L1.
  • shear-deformable elastic bearing bodies 11 instead of sliding bearing bodies
  • these result in a particularly advantageous manner the desired control of the distance between the slats between the two joint edges.
  • the shear-deformable bearing bodies 11 transmit their deformation forces to the lamellae, so that these are set at the same mutual distances and equal distances from the joint edges on the cross members Q1, Q2.
  • a prerequisite for controlling the slats in this way within the overall construction is a chain of partial crossbeams T10 - T60 that runs from joint edge to joint edge, whereby the short partial. trusses T10, T60 are connected to the joint edges, eg in the area of the edge slats LR1, LR2.
  • the longer partial traverses T20-T50 are each rigidly connected in the middle, as shown in FIG. 16, via connecting bodies 12 to the associated lamellae; their ends are received between bearing bodies 11 in each case in the opening area of the adjacent lamellae, here again the bearing body 11 in the form of sliding bodies or, for the purpose of simultaneously achieving control of the lamellae, as thrust-deformable elastomeric bearing bodies.
  • the bearing body 11 are preferably biased in the vertical direction, so that the construction works without play and noiselessly.
  • FIG. 17 shows a short length section of a bar-shaped lamella 13 with a steel bracket 14 welded to its underside.
  • a partial cross member 16 is connected between shear-deformable ' bearing bodies 11.
  • Such steel brackets are available in a corresponding number and arrangement for receiving the cross members and the cross members.
