Definitions

  • the invention relates to a bridging device for expansion joints in bridges or the like, with lamellae running transversely to the longitudinal axis of the traffic path, which are mounted on cross members that are rotatably and / or displaceably supported in the joint edges and that bridge the joint.
  • a bridging device for expansion joints in which slats extending transversely to the longitudinal axis of the traffic path are supported on both sides in the joint edges in a rotatably and displaceably supported manner that supports the joint diagonally bridging.
  • U-shaped brackets are welded to the underside of the lamellae, in which elastically flexible slide-pivot bearings which are pivotally connected to the lamellae are arranged, in which the cross members are displaceably guided.
  • the crossbeams are arranged at an angle to one another. This makes them stand out In the longitudinal direction of the slats directed force components of the horizontal forces on each other, so that there is no risk of one-sided migration of the slats.
  • a disadvantage of this known construction have been the differing support spacings for the slats.
  • the slats have to be reinforced at the points where they are further stretched in a complex manner in order to ensure the necessary bending stiffness for loads, such as occur in heavy goods traffic.
  • the crossbeams twist around a vertical axis, because due to the arrangement of the swiveling crossbars at an acute angle to the direction of movement of the superstructure, the angle between the swiveling crossbars and the slat direction or the two joint edges changed.
  • a simply constructed bridging device for expansion joints is to be created, in which the lamellae are supported at equal intervals by the crossbeams and the force components resulting from movements of the superstructure and from the traffic loads are safely absorbed.
  • the control forces are transmitted via the inclined cross beams.
  • the parallel arrangement of the diagonal cross members ensures a uniform support spacing, so that it is not necessary to reinforce the slats.
  • Caused by movements of the bridge superstructure horizontal control forces generate force components in the longitudinal direction of the slats due to the parallel arrangement of the diagonal beams.
  • These are received by at least one additional cross-beam designed as a guide cross-beam, which is preferably arranged at the edge and can be arranged in the direction of displacement of the superstructure or at an angle, in particular against the direction of the cross-beam.
  • the guide crossmember can simultaneously take on the function of a cornice crossmember, which is required at the two ends of the joint construction as a vertical support for the slats and forms a guide for the slat ends, so that vertical displacement of the slat ends is prevented.
  • an additional control mechanism is provided, the control forces of which counteract the frictional forces which result from the control force components of the slats acting in the longitudinal direction of the slats.
  • This control mechanism can advantageously be formed by elastic control springs which are provided in the region of the guide crossmember or the guide crossmembers. The control springs are arranged laterally between the slats and counteract the frictional forces. Linkage control can also be provided as the control mechanism.
  • the cantilevered slat ends are designed to be horizontally rigid, otherwise a horizontal bending of the slats and thus jamming on the guide crossbar could occur.
  • additional guide devices on both the side surfaces of the guide crossmember and on the projecting lamella ends are provided, wherein these guides can be formed by pressure sliding bearings which are arranged in a U-shaped bracket on the underside of the respective lamella on both sides of the guide crossmember.
  • the side surfaces are provided with a sliding layer, the z. B. can be formed from sheet steel.
  • the pressure sliding bearings can be coated with PTFE on their contact surface. Due to the additional thrust bearings, larger forces acting in the longitudinal direction of the joint, which are not absorbed by inclined traverses, are safely absorbed by the guide crossmember, particularly in the case of large roadway widths. In the case of very large joint lengths and because of the changing direction of the longitudinal forces, it can also be advantageous to arrange a second guide cross member on the opposite edge of the road in order to keep the forces transmitted to the guide cross member lower.
  • a device is provided between the guide crossmember and the respective lamella, which secures the projecting end of the lamella against vertical displacements.
  • This device can be formed by slide bearings arranged on the top and bottom of the guide crossmember, provided in a bracket below the lamella, in particular a pressure slide bearing which has guide strips encompassing the guide crossmember at the top and bottom such that the bearing in connection with the guide crossmember prevents that the slat can lift up.
  • such devices can on both opposite sides of the projecting lamella ends be provided, but it is also conceivable that a guide crossmember is provided on one edge side and a cornice crossmember is provided on the opposite edge side, which prevent lifting of the lamella ends in the vertical direction in the embodiment described.
  • FIGS. 1 a to c four slats 3 are arranged to bridge a joint between the joint edges 1, 2 in the direction of the joint, that is to say in the transverse direction. While the joint edge 1 is formed by the bridge, the joint edge profile 2 forms the fixed abutment.
  • the slats 3 are mounted on a series of mutually parallel inclined cross members 4, 5, 6, of which only three are shown for the sake of clarity, and on an edge-side guide cross member 7 which is arranged in the direction of movement of the superstructure 1, that is to say transversely to the slats 3 is.
  • the lamellae 3 are supported by slide pivot bearings 8 on the inclined cross members 4, 5, 6, which in turn are supported in recesses in the joint edges by slide pivot bearings 9.
  • the oblique cross members 4, 5, 6 and the guide cross member 7 are fixed in the edge profile 2 by means of pivot bearings 10. Since the guide cross member 7 has the same direction as the direction of movement 11 of the superstructure 1, a simpler, rigid bearing can also be used here instead of the pivot bearing 10.
  • control springs 12 are arranged in the spaces between the lamellae 3 and between the lamellae and the joint edges in order to ensure the setting of a uniform lamella spacing in the area of the guide cross member when the joint width changes.
  • These control springs are designed as compression springs and consist of cell polyurethane or a similar material.
  • a spring formation according to has been particularly suitable.
  • the control forces for adjusting the slats are generated in the remaining area of the joint by the obliquely arranged oblique cross members, so that no elastic control elements are required for this.
  • the edge-side control springs therefore only serve to track the slats in the area of the guide crossmember 7, in order to avoid bending of the projecting slat ends in this area, which would otherwise be possible as a result of control movements.
  • the guide cross direction is not the same as the direction of movement of the superstructure 1, then the slats on the guide cross must be pivoted, and the guide cross itself must also be rotatably guided in both joint edges.
  • the advantages of this arrangement are the avoidance of constraints on the slats and Guide truss supports for unscheduled joint movements. Control forces are generated at the lamella or support points during joint movements.
  • the lamellae are mounted on pressure slide bearings 13 (see FIG. 3) or 14 (see FIG. 6), which are located on the side of the guide crossmember 7 support, for the removal of the reaction forces occurring on the inclined crossbeam supports 8 and acting in the longitudinal direction of the lamellae 3.
  • the guide crossmember 7 can - as described above - be arranged so as to be inclined in the opposite direction to the inclined crossmembers 4, 5, 6.
  • a device described with reference to FIG. 5 is preferred, by means of which the free ends of the lamellae are fixed in a cornice crossbar 15 which also acts as a guide crossbar.
  • the lamella has at its free end a stop 16 which has a pressure sliding bearing 17 with an elastomeric part 18 and a steel profile 19 with attached guide strips 20, 21.
  • the steel profile and the guide strips are provided with a sliding layer made of PTFE 22 on their sliding surface facing the cornice cross member.
  • On the opposite flank of the There is also a pressure slide bearing 23 in the guide crossmember.
  • tensile or compressive forces resulting from the control forces and acting in the longitudinal direction of the lamellae are transmitted to the guide crossmember via these pressure slide bearings.
  • the guide strips 20, 21 prevent vertical movement of the slats upwards.
  • the same construction can be provided on the opposite side of the lamella, but it is sufficient if the control forces are absorbed only on one side of the bridging construction by means of a guide cross member.
  • a cornice cross member 24 known per se is provided, which extends through a pane 25 arranged on the underside of the lamella 3.
  • FIG. 6 An alternative embodiment is shown in FIG. 6, in which a U-profile 26 is provided below the lamella 3, in which the sliding pivot bearings 8 and the pressure sliding bearings 14 are arranged. From Fig. 6 it can also be seen how the oblique crossbeams on the underside and on the top are each slidably guided between grooves of a lower and an upper bearing body 8. These bearing bodies have an essentially disk-shaped projection which is rotatably mounted in corresponding recesses on the lamella or on the bracket base.
  • the slide swivel bearings are installed under vertical preload to prevent the trusses from being lifted off the bearings.
  • the inclined traverses are mounted in the same way with slide pivot bearings in the truss boxes, and in order to avoid sliding out of their bearings at the joint edges, stops are provided at their ends.
  • the guide cross member 7 is guided on its underside 27 and its top 28 between square bearing plates into which corresponding grooves are milled.
  • These bearing plates can additionally - as with the sliding pivot bearings - with the help of disc-shaped cams 29 on the underside of the slats or be rotatably mounted on the bracket base, provided the guide cross member 7 does not run in the direction of movement of the superstructure.
  • the exemplary embodiment shown shows a guide cross member 7 which is arranged obliquely to the direction of movement of the bridge superstructure 1. 6 also shows that the pressure sliding bearing 14, between which the guide cross member 7 is guided without play on its two side surfaces 30, has sliding foils 31 to reduce the friction.
  • the guiding of the slats on the guide cross member 7 through the thrust bearing 14 enables the absorption of large tensile and compressive forces acting in the longitudinal direction of the slats. This is necessary because all the forces introduced in the longitudinal direction of the lamellae, which occur as a result of horizontal wheel loads from traffic or when the superstructure moves due to the oblique arrangement of the diagonal cross members, must be absorbed by the guide cross member.
  • the cross-section of the guide cross member is therefore also adapted to the lateral loads.
  • a corresponding, sufficiently dimensioned receptacle with laterally guided slide bearings is provided for the two ends of the guide crossmember in the crossbar boxes.
  • the above-described arrangement of the oblique cross members and the guide cross member or guide cross members has the advantages that the span of the parallel slats in the movable area is constant.
  • the control behavior can be improved by the possibility of arranging the diagonal cross members at an acute angle to the lamella.
  • the oblique angle is very large due to the fact that two adjacent cross members increase in spread uneven span of the slats limited in this truss field. This limitation does not apply if the diagonal beams are arranged in parallel.
