Definitions

  • the invention relates to a device for bridging expansion joints in traffic routes, in particular bridges, with one or more lamellae running parallel to the traffic route direction and parallel to one another, which adjoin the ceiling of the traffic route upwards and downward on traffic route edges which run transverse to the expansion joint, into the adjacent traffic route edges or indirectly supporting crossbeams, and a device for controlling the lamella spacing is provided.
  • German patents 16 58 611 and 30 19 594 there is a need to control the spacing between the lamellas in accordance with the respective width of the expansion joints and also in response to braking and starting forces of vehicles traveling over them.
  • control devices which, by using different means such as articulated levers, scissors linkages, toothed racks, elastic control parts or the like, effect the control of the slats in such a way that these subdivide the joint gap evenly.
  • the known lever controls (e.g. German Offenlegungsschrift 24 21 964) have no shock-absorbing effect; their joints flap over time.
  • the known elastic control devices e.g. German patents 16 58 611 and 30 19 594 are less precise than the lever controls mentioned, the inaccuracy increasing with decreasing deflection forces, but also with increasing age of the rubber-elastic control parts.
  • the present invention has for its object to provide a control device on a device of the type mentioned, which works with high accuracy, responds immediately to any deflection caused by traffic loads and avoids a sudden power transmission.
  • the sequence control proposed according to the invention enables the control of a single, isolated or each lamella of such a bridging device.
  • the control takes place either via load-bearing crossbeams and / or via additional, non-loadbearing crossbeams that serve to control the system, so-called steer crossbeams.
  • Trusses including control crossbars are only permanently connected to one slat; the rope strands provided on the traverses are each connected to a slat or a traffic route edge.
  • the crossbeams on which this slat is supported bridge the expansion joint and the cable strands are each connected to a traffic route edge.
  • slats they are adjacent lamellae connected to the respective traffic route edge with trusses, the control cables of which are attached to the edge of the joint with a rope strand, with the other to the adjacent lamella.
  • the middle lamellae are fastened to trusses, the cable strands of which are each connected to an adjacent lamellae.
  • other lamellae that are equally far apart from the fastening point of the controlling crossmember are also possible.
  • control crossbeams which only bridge part of the expansion joint, ie do not run from one edge of the traffic route to the other.
  • control crossbars each of which is firmly connected to a lamella, bridge the entire expansion joint in a staggered arrangement, all control crossbars being provided with a control cable. It is expedient that the two slats adjacent to a certain slat are each coupled to a cable strand of the control crossbar firmly connected to the certain slat are.
  • the continuous control chain composed of such control crossbars can simultaneously serve to absorb vertical loads, namely if the slats not firmly connected to a control crossbar, for example slats controlled by it, are slidably supported on the control crossbar or are supported by elastic, thrust-deformable bearing bodies (cf. German patent specification 30 19 594).
  • the rope control proposed according to the invention is sufficiently elastic due to the rope stretching, so that disturbing shock loads are avoided; it is also sufficiently precise within the permitted stretches, so that control movements can be achieved even with relatively small deflection forces, according to which those are firmly connected to a steering crossmember Slat is set in the middle between the two slats controlled by this traverse, or a controlled slat and a joint edge.
  • a single lamella 3 is arranged between a left-hand traffic route edge 1 and a right-hand traffic route edge 2.
  • sections 4 of the traffic route edges are the ends of a load-bearing cross member 6 bridging the expansion joint 5 between the upper bearing parts 7 and lower bearing parts 8 slidably mounted.
  • the lamella 3 is supported on the crossmember 6 by being firmly connected to the crossmember 6 via an intermediate piece 9.
  • the joint edges are preferably made of concrete, but can also be reinforced by a steel structure in the edge area.
  • Lamella 3, cross member 6, intermediate piece 9 are preferably made of steel, the intermediate piece 9 being welded to the lamella 3 on the one hand and to the cross member 6 on the other hand.
  • the bearing parts 7, 8 are preferably elastically prestressed plastic blocks in the vertical direction, for example made of neoprene.
  • deflection rollers 10 are fastened at both ends, via which a control cable 11 is guided.
  • the control cable 11 preferably consists of a closed cable loop in the manner of an endless cable, the cable ends being connected by means of a tensioning or tensioning device (not shown in more detail).
  • the control cable can also be interrupted at any attachment point.
  • the control rope 11 comprises two rope strands, namely an upper rope strand 12 and a lower rope strand 13.
  • the upper rope strand 12 is via a fastening point in the manner of a clamp 14 with the left joint edge 1, the lower rope strand 13 is via a further clamp 15 with the right one Joint edge 2 connected.
  • the spaces between the two joint edges 1, 2 and the lamella 3 are with sealed by means of elastic sealing profiles, not shown.
  • a corresponding removal or approach of the two clamps 14, 15 necessarily causes the central position of the lamella 3 to be maintained.
  • the lamella 3 is supported on a plurality of cross members 6, the number of cross members depending on the width of the Traffic route aimed, but at least two.
  • Fig. 2 shows a section of a bridging device for a wide expansion joint, with five lamellae are shown in the view from below.
  • the two outer slats 16 can either be interpreted as freely movable slats, as the three middle slats 17; but they can also be understood as edge lamellae permanently connected to the edges of the traffic route. There is no difference for the control principle. If the outer lamellae 16 represent so-called edge lamellae, the three control traverses 18 which are used solely for the control and therefore do not remove vertical loads can form a closed control chain connecting the two traffic route edges; otherwise would be to continue this control chain with further control beams.
  • the load-bearing crossbeams are gem. Fig. 2 not shown.
  • connection points 19 of the control traverses 18 with the slats 17 assigned to them are each drawn in by a lattice-like structure.
  • deflection pieces 26 with semicircular slideways are provided at the ends of the control crossbeams 18 .
  • these deflection pieces can be formed from a hard elastomeric clamping parts 20 which are plugged onto the end 21 of the web 22 of a double T-profile 23 which forms the partial cross members.
  • the elastomeric clamping part 20 advantageously supports the elasticity of the control.
  • rope pulleys rotating about vertical axes can also be provided.
  • the sectional view acc. Fig. 4 shows such a clamping part 20 with a recessed slideway 24, in which a band-shaped control cable 25, which is composed of three adjacent individual ropes and a support 28 made of sliding material, for example PTFE, is slidably guided.
  • a band-shaped control cable 25 which is composed of three adjacent individual ropes and a support 28 made of sliding material, for example PTFE, is slidably guided.
  • Such control cables 25 surround also the control crossbeams 18 shown in FIG. 2, such that the opposite cable strands of these control cables lie in horizontal planes.
  • the two rope strands are freely stretched between two opposite deflection pieces 26 and each connected to a lamella 16, 17 via a clamp 27.
  • All of the horizontal displacements introduced via a single lamella or over the edges of the traffic routes are transmitted by means of the control cables 25 to all the lamellas or traffic route edges, with the result that the lamellae 16, 17 adjust such that their mutual distances and the distances between the outer lamellae the edges of the traffic routes are the same size.
