Definitions

  • the invention relates to a track superstructure Rails for rail vehicles, the Rails detachable with fasteners with support plates are connected and between the rail foot and support plate an intermediate plate is arranged.
  • the track superstructure is subject to ever higher mechanical loads on the one hand to the higher increasing axle pressure of the vehicles and to those that have been rising particularly recently Speeds. So are cruising speeds for Passenger trains of 200 and more km / h already in many places realized and also speeds for freight trains with 120 km / h also introduced. With this double One must increase the load on the track superstructure particularly safe and durable construction selected will. Furthermore, the lifespan of a Track superstructure to ensure a certain, albeit there may be slight vertical mobility, d. H. below the rail must be an elastically deformable Body be arranged. This rubber-elastic deformable The body also has the task of forwarding the To weaken structure-borne noise from the rail to the superstructure. Out AT-B-387.249 is one such elastomer Intermediate plate known over the entire surface distributed, openings or blind holes that should make up a certain minimum volume. Thereby particularly high sound insulation should be achieved.
  • the central area is a Base plate made of elastic material under the Rail foot a constant higher resistance against Deformation than has at its edge area.
  • Base plates are for example DE-B1-2 006 071 or DE A1-2 032 915.
  • GB-A-2 152 119 describes a threshold which Detachably attached rails. Between threshold and Rail is an intermediate plate for electrical and dynamic Isolation of the rail from the threshold is provided.
  • the Task in this patent application is that the life of such an intermediate plate can be increased should. Furthermore, it should be avoided that one too compliant Intermediate plate the rail from its seat on the threshold high stress is pushed out. To the lifespan too increase the lateral mobility of the intermediate plate which goal should be achieved through recesses. The volume of these recesses can be so large that a middle area is present, which has no material.
  • the intermediate plate should be designed so that the Edge areas which have no recesses or grooves, with at least a 20 mm area of the intermediate plate come to rest below the rail foot.
  • British patent application 2 154 635 also relates to a threshold with releasably attached rails, being between Rail base and threshold an intermediate plate with recesses is arranged.
  • the task is also here, the lifespan to increase the intermediate plate.
  • the intermediate plate has one middle area, which has recesses or grooves, whereby the stability should also be increased by the same.
  • the present invention has set itself the task of To create track superstructure that also with good sound-conducting Materialicn, such as concrete and steel, allowed Forwarding of structure-borne noise from the rail to the track superstructure dampen, a mobility of the rail in the vertical direction allowed and at the same time a rolling movement of the rails largely prevented.
  • the track superstructure according to the invention with rails for ski bound Vehicles the rails with fasteners releasable, e.g. B. via screws and clamps, with support plates, e.g. B. concrete slabs, steel sleepers, prestressed concrete sleepers, are connected, and between the rail foot and support plate at least one elastically deformable, in particular plane-parallel, Intermediate plate is provided, which can be laterally extends over the screws, the intermediate plate in essentially extending parallel to the longitudinal direction of the rail Areas of different rubber-elastic deformability and a middle area, which is the normal projection of the rail head includes, transverse to the longitudinal direction of the rail seen, is provided, which is a larger rubber elastic Has deformability than the subsequent outer areas, consists essentially in the fact that the middle area of the Normal projection of the rail foot corresponds and in particular an essentially constant rubber-elastic deformability having.
  • support plates e.g. B. concrete slabs, steel sleepers, prestressed concrete sleepers
  • the different rubber-elastic deformability can particularly easy and targeted due to material weakening be educated.
  • the material weakening is formed by blind holes, on the one hand, the overall structure of the intermediate plate least disturbed and on the other hand is an intrusion of contaminants such as sand and the like. Like, in the Rail fastening construction avoided.
  • the areas can be different rubber-elastic deformability from different Materials exist.
  • a strand be extruded in the mouth of an extruder several strands of an analog material, however differently cross-linked material, put together will.
  • the intermediate plate essentially does not have one stretchable layer that runs parallel to the rail foot is oriented, the obstacle to the swaying movement of the Supported rail still particularly favorable in that Changes in suspension behavior due to the change in length can be avoided.
  • the essentially inextensible layer can be covered with a tissue embedded in the material of the intermediate plate, in particular steel mesh, be formed, due to the particularly sophisticated technology like it for example with handrails for escalators, Vehicle tires and. Like. was developed, a special easy adaptation of the production process allowed and further the life of such an intermediate plate can be increased particularly easily.
  • Consists of the essentially inextensible layer a steel plate connected to the intermediate plate, e.g. B. is glued or vulcanized, so is one hand a particularly simple assembly possible, wherein Changes in length during a load are particularly favorable can be avoided.
  • the intermediate plate is made of a foam, whose density is transverse to the longitudinal direction of the rail outside, especially continuously, increases Get intermediate plate that is particularly accurate in your Suspension behavior can be set as it for example, is only required when Manufacturing process, for example in extrusion, of such a profile the individual areas different amounts of pore-forming material, for example, to add fluorocarbons.
  • the 1 shown track superstructure according to the invention in Section has a rail 1 with head 2 and foot 3. Of the Rail foot 3 rests on an intermediate layer 4, one Angle guide plate 5 and an intermediate plate 6 on the Support plate 7 made of reinforced concrete. The attachment takes place via the tension clamp 8, which is screw 9 is held down by the dowel 10 in the Support plate is screwed in.
  • the intermediate layer 4 exists from a thin rubber-elastic layer, the is plane parallel and a completely homogeneous Behavior.
  • the angle guide plates are out a rigid material formed by cooperating the wedge-shaped parts 11 with appropriately trained Troughs 12 in the support plate a lateral migration of the Rails, for example in curves, can be prevented should.
  • the intermediate plate 6 shown in Fig. 2 in plan view has a length of 30 cm, width of 17 cm and height of 10 mm on. As can clearly be seen, there are two oblong holes 13 provided by which the screws 9 in the Assembly.
  • a central area 14 is provided, which is delimited by two dashed lines, from the two outer areas 15, is bordered.
  • the middle one Area 14 has material weaknesses in the form of grooves 16 which run in a zigzag shape with a uniform depth. These grooves 16 are each not over the edges, so that the ingress of contaminants such as sand or the like, is safely avoidable.
  • In the outer areas 15 gradually increases the volume of the weakened material by reducing the overall course of the grooves.
  • a Similar behavior can also be achieved in that not the overall course is reduced, but only the depth of the grooves is varied, which also causes that Volume of material weakening in the middle area can be kept larger than in the two Marginal areas.
  • zigzag or meandering grooves can, for example production-related reasons also in the transverse direction Intermediate plate straight grooves be provided, such a product particularly can be easily obtained by extrusion of a strand can, which is then only cut to length and with appropriate Oblong holes must be provided.
  • blind holes 17 and 18 are the Material weaknesses formed by blind holes 17 and 18.
  • the central area 14 has regularly distributed Blind holes 17 of uniform size and depth.
  • the outer areas 15 have blind holes different Size, with the blind holes 17 'the same volume as those of the central region 14, whereas the Blind holes 18 have a smaller volume.
  • the blind holes can also cover the entire Plate be evenly distributed, in which case the depth of the same with the same diameter to the outside decreasing in the two outer areas 15 design, and in the middle area the blind holes have a uniform depth.
  • the intermediate plate 6 shown in section in FIG. 5 is constructed with two partial plates 19, 20, the middle area 21 again by dashed lines Lines vis-à-vis the outer areas 22 is shown delimited.
  • the sub-plate 20 has one greater shore hardness than plate 19.
  • the middle one Area 21 of both sub-plates is made plane-parallel and accordingly has a uniform rubber-elastic deformability, whereas the Both outer regions 22 are formed so that the Partial plate 20 with greater Shore hardness one to the outside has a wedge-shaped increasing thickness, whereas the outer areas 22 of a softer material existing partial plate 19 to the outside a decreasing Have thickness.
  • the two partial plates are together connected via an adhesive adhesive layer.
