Definitions

  • the present invention relates to a bridging device for an expansion joint arranged between an abutment and a superstructure in a drivable structure, having the following features:
  • abutment and the superstructure Between the abutment and the superstructure extend a plurality of the joint gap bridging trusses, which are supported on the abutment and the superstructure; between the abutment and superstructure a plurality of slats extending in the longitudinal direction of the joint is arranged, which in each case are supported on at least part of the trusses; the distance of the slats to each other is controlled by spring means to which the respective slats are connected.
  • Bridging devices of the type specified above, as they are used in particular in bridge construction are known in various designs. Variations exist, for example, with regard to the mounting of the trusses by being firmly clamped on one side (cf., for example, DE 19607593 A1) or slidingly supported both on the abutment and on the superstructure (cf., for example, DE 3201751 C2).
  • the slats can be slidably supported on all trusses; or individual or all lamellae are fixedly connected with associated, in each case both on the superstructure and on the abutment slidably supported trusses, in which case a sliding support of the lamellae on the other trusses possible, However, it is not mandatory.
  • the spring devices which are connected in series in the form of a timing chain, should provide each other as uniform spacing of the slats.
  • Such a control of the lamellar spacings via said spring devices is superior to a lamellar positive control (cf., for example, EP 0215980 A1), which ensures exactly the same lamellar spacings, insofar as it is much less susceptible to damage resulting from possible constraints can .
  • These constraints can be due to design (in the case of very large bridging devices due to the limited possible inclination of the trusses) as well as external influences (eg: jamming of a slat due to dirt in the sliding surfaces, blocking of a single slit due to dirt or foreign bodies (eg stone) etc.).
  • the present invention has set itself the task of providing a bridging device of the type described above, which is particularly suitable for a comparatively small constructional and manufacturing effort, especially for very large joint widths, namely by opening individual columns above a permissible level beyond usually alone the control springs, d. H . without this attacks are required is reliably avoided. It would be particularly desirable if in the other areas of operation of the lock-up device, for. B. at a comparatively small joint width, the gap widths of the individual gaps would have a uniforming effect.
  • this object is achieved in that the individual spring devices depending on their arrangement within the device provide different control forces, wherein the j ehyroid control force of the spring means transversely to the joint longitudinal direction has a gradient.
  • the towards the Timing chain different control forces of the individual spring devices allow in particular a consideration ofjj in a sliding support of the slats on the trusses between the slats and the trusses acting frictional forces to be overcome in a tracking of the slats due to a change in the joint width and from lamella to Add up lamella.
  • the frictional forces acting between the slats and the crossbars, compensating for the compensating movements of the slats as the width of the joint changes, which in the case of cantilever trusses, slide from one joint edge to the other joint edge and, in the case of both sides, slidably supported
  • such generic bridging devices which are designed for particularly large joint widths and accordingly have a particularly high number (eg over 15) of lamellae can as a rule be solely controlled by the control force gradient according to the invention and thus without compulsory Preventing the slats and without the use of attacks reliably prevent the opening of individual columns beyond a permissible level.
  • the present invention is not only advantageous in this respect; Rather, it can, which is a quite surprising result, under the conditions explained below in more detail also in other operating states of the lock-up device (eg, with a comparatively small joint width) have a favorable effect on a homogenization of the lamellar spacings.
  • the gradient of the control force expediently extends over the entire joint width.
  • the spring means at maximum joint width in each case an acting in the sense of reducing the fin spacing voltage, so the Steuerkraftgradient is to be chosen so that the j erous control force of the spring devices in the direction of the clamping of the trusses sliding support increases.
  • acting at maximum joint width in the sense of increasing the fin spacing voltage of the spring means of the gradient runs in the opposite direction.
  • the individual spring devices provide different control forces, the respective control force of the spring devices being offset by two opposite control force gradients, in each case from the center of the joint gap in the direction of its edges Dependence on the direction of the tension of the spring units - increasing or decreasing. If the spring devices at maximum joint width have a tension which acts in the sense of reducing the lamellar spacing, then the respective control force of the spring devices increases in the direction from the center of the crossbars to the joint edges. In a chip tion of the spring means at maximum joint width in the sense of increasing the fin spacing decreases in contrast to the j e ownership force of the spring devices in the direction of the center of the trusses to the joint edges.
  • the present invention is, moreover, also suitable for use in such bridging devices, in which the or. several lamellae are in each case firmly connected to each other with different trusses slidingly supported on both sides, and in which the trusses thus shift to varying degrees as the joint width changes; because here too, the frictional forces between the traverses and the superstructure, which accumulate in the direction of the timing chain, can be reduced. the abutment can be compensated using the invention in the sense of an equilibrium of forces.
  • bridging devices designed for extremely large joint widths (eg with 30 or more lamellae)
  • every tenth lamella can be force-controlled.
  • slats as such measures such as cable controls.
  • the maximum, caused by the Steuerkraftgradienten total gradient of the control force is dependent on a number of factors such as in particular the construction the bridging device (trusses mounted on one side or sliding on both sides), the number of lamellae and the sliding behavior of the lamellae on the trusses.
  • the overall gradient generally increases with the number of slats and the increase in the coefficient of friction of the sliding bearings of the slats.
  • the present invention can be implemented with spring devices of various designs. Particularly good results can be achieved with spring devices comprising spring elements designed as elastomer springs, wherein the corresponding elastomer blocks are stressed in particular to shear.
  • spring devices comprising spring elements designed as elastomer springs, wherein the corresponding elastomer blocks are stressed in particular to shear.
  • a so far in terms of size and cost particularly preferred development of the invention is characterized in that the spring units of two adjacent spring means in each case one connected to the middle of three adjacent slats rigidly connected plate to which the two adjacent slats on thrust springs in the form of elastomer blocks are coupled.
  • the elastomer blocks are preferably stress-free in a neutral position between the minimum and maximum gap widths of the bridging device (see above).
  • the spring means may comprise a plurality of control units distributed between each two adjacent trusses distributed spring assemblies, wherein jumps in the control force within the timing chain of the individual control fields in the various control fields are offset from one another.
  • control force according to the relevant gradient does not necessarily have to increase or decrease from single gap to single gap; rather u can.
  • a plurality of mutually adjacent lamellae form a group in the sense that the spring devices acting between them are designed for matching control forces. The associated deviation from a theoretically optimal control force characteristic is justifiable and justified by cost savings.
