Definitions

  • the invention relates to a device for bridging expansion joints in carriageways, bridges or the like, with slats running parallel to the joint edges, which are displaceably supported on the cross-bridges bridging the joint and whose distances can be adjusted in a controlled manner by means of elastomeric shear springs which change the joint width Connect the lamellas with one another and with both joint edges in the manner of a closed timing chain.
  • Such a known device (DE 33 33 880) describes a direct attachment of the thrust springs to the undersides of the slats.
  • the thrust springs provide satisfactory control here the lamellae, so that the lamella distances between the opposite joint edges are approximately the same size; the fact that in the longitudinal direction of the slats there are a plurality of timing chains formed from thrust springs, there is moreover a torsion-free support of the slats with respect to a vertical axis; however, the thrust springs make no contribution to preventing the slats from tipping, ie to prevent rotation about their longitudinal axes. To prevent the slats from tilting, special measures are therefore required in the known device.
  • the lamellae are supported against one another and against the joint edges by two rows of rubber buffers arranged one above the other.
  • the lever arm for the return moment against tipping corresponds to the vertical distance between the upper and lower rows of rubber buffers.
  • the present invention has for its object to improve the elastic support of the slats against each other and against the joint edges in a device of the type mentioned, with the aim that the slats are held against tipping, regardless of the structural design of the supporting components the device.
  • timing chains are provided in horizontal planes spaced one above the other and that the thrust springs of at least one timing chain are attached directly or indirectly to rigid supports which are directed downwards from the slats protrude.
  • the arrangement of the supports makes it possible to arrange the two timing chains one above the other at a freely selectable vertical distance, preferably under the slats. Regardless of this, the lamella cross-section, and of course also the cross-member cross-section, can be designed according to the loads on the joint transition. A mutual one There is no influence between the dimensions of any structural components of the device and the arrangement of the timing chains on the supports.
  • the proposal of the invention creates the possibility that both the control force on the one hand and the restoring torque on the other hand can be selected independently of one another for the tilt protection.
  • the control force is determined by the course of the spring characteristic of the thrust springs; regardless of this, the restoring torque is determined by the lever arm, ie the vertical distance between the two timing chains. Both variables, spring stiffness and restoring torque, can therefore be varied independently of one another. It is essential that the shock-absorbing properties of the overall construction are unrestricted by the shear springs used according to the invention. Since, as already mentioned, the dimensions of the lamellae and crossbeams have no influence on the control force or the restoring torque, the overall construction can be optimally designed in all parts.
  • a preferred embodiment provides that the supports are attached to the underside of the slats between the cross members, elongated profile parts. According to the slats, the supports are close together. On each support, two timing chains engage on the opposite sides in the slat direction. These timing chains can have a different structure.
  • shear springs are fastened at one end to a support or a joint edge with the other end to a rigid tab, and that each tab connects either the shear springs of the joint edge and a support or two supports.
  • the shear stress in the shear springs when the joint is closed is zero. As the joint opens, the shear stress, and accordingly the control force, increases linearly.
  • the thrust springs are each fastened at one end to a support or a joint edge and at the other end to a rigid counterpart, and that each Counterpart is attached to a column or a joint edge.
  • timing chain acts on the supports, while a second timing chain sits directly on the underside of the slats, such as in the device known from the first-mentioned document.
  • constructions with other spring elements such as compression springs, instead of thrust springs; however, such constructions are complex; they also have the disadvantage that their preload decreases relatively quickly due to aging of the elastomeric material. Such constructions can therefore be disregarded due to their lack of practical suitability.
  • the device for bridging expansion joints shown in different sections in FIGS. 1 to 4 comprises supporting elements with slats 1 that terminate on the surface of the respective traffic route or the respective carriageway and are slidably mounted on the cross members 3 bridging the joint 2. So that the slats 1 cannot lift upwards, they have U-shaped brackets 4 on their underside, through the openings of which the cross members 3 are inserted. Within the bracket 4, the cross members 3 are supported in a sliding manner up and down by elastomeric bearing pieces 5 that are prestressed in the vertical direction. Similarly, the cross members 3 are at their opposite ends on horizontally projecting shoulders 7 of the opposite joint edges 6 stored. 2, an edge bar 8 is firmly connected to the joint edge 6 opposite the shoulder 7 of a joint edge.
  • the edge beam 8 is preferably constructed identically to the slats 1, which considerably simplifies the connection of the overall construction to the joint edges.
  • a control device is connected to the edge beam 8, which comprises control chains formed from thrust springs 9, each control chain forming an elastic connection of the slats 1 with one another and with the edge beams 8.
  • the thrust springs 9 are seated at one end on vertical supports 10 fastened to the underside of the lamellae 1, at two different heights. In this way, there are two control chains arranged at a vertical distance h on the supports 10, which are shown in a side view in FIG. 3. A top view of the lower timing chain is shown in FIG. 4.
  • the thrust springs 9 of adjacent slats 1 or a slat 1 and an edge beam 8 are connected to one another via rigid tabs 11, so that the thrust springs 9 deform, increasingly, the more the joint widens.
  • both the lamellas or edge beams and their supports 10 lie side by side, the shear springs 9 relaxing are.
  • the thrust springs 9 act as points of attack for restoring forces R1, R2, which form a restoring torque against tipping with the lever arm h.
  • Fig. 4 the lower timing chain is shown at approximately the middle joint opening, ie the shear deformation of the shear springs 9 achieved here corresponds to approximately half the value of their maximum control force.
  • the situation is somewhat different in the variant shown in FIG. 5. Only half as many thrust springs 9 are provided here.
  • the shear springs 9 are de-energized in the drawn central joint opening. Because the thrust springs 9, unlike in FIG.
  • brackets 4 can also be used as varinates of the supports 10, provided that extensions 13 projecting downwards are attached, which are shown in broken lines.
  • the thrust springs were each attached to the outer sides of the extensions 13 or a bracket 4 facing away from one another.
