Definitions

  • the invention relates to a track superstructure with rails for rail-bound vehicles, the rails being detachable with fastening means, e.g. B. via screws and clamps, are connected to support plates, and at least between the rail base and support plate, a rubber-elastic intermediate plate is provided.
  • Tracks for rail-bound traffic can either be provided with a ballast bed or a so-called fixed track.
  • a track For a track to function properly, it must be able to deflect it under load. However, such a deflection process should not exceed a certain depth, even under the most varied loads, such as, for example, a locomotive, a passenger car, a loaded or unloaded freight wagon.
  • loads such as, for example, a locomotive, a passenger car, a loaded or unloaded freight wagon.
  • compression could be achieved by compressing the ballast bed. Due to the material properties of the wood, vibration damping occurs. between also in the area of acoustics.
  • Sound-conducting materials such as concrete, steel and.
  • an intermediate plate made of elastomeric material is known from AT-B-387.249, which is distributed over the entire surface and has openings or blind holes which have a certain minimum volume. This training is intended to achieve particularly high sound insulation.
  • the central region of such a base plate with regions of different elastic deformability in relation to the direction normal to the rails.
  • the middle region has a higher resistance to deformation than the side regions.
  • the central region that is to say the region which lies below the rail head, has less resistance to deformation, so that the rail with its Foot lies in a kind of trough of the intermediate layer when it is subjected to a load.
  • the present invention has set itself the goal of providing a track superstructure which allows a limited elastic deflection of the rails under load, in which the transmission of the sound from the rails to the base plates, sleepers or the like is limited, and the higher Stress causes a greater resistance to deformation, with which longer service lives of the rubber-elastic intermediate plates can be achieved.
  • the track superstructure according to the invention with rails for rail-bound vehicles, the rails being detachable with fastening means, for. B. via screws and tension clamps, with support plates, e.g. concrete support plates, steel sleepers, reinforced concrete sleepers, and between the rail base and support plate at least one elastically deformable, in particular plane-parallel, intermediate plate is provided, which optionally extends to over the fastening means, the intermediate plates Areas of different deformability with recesses which incomplete penetrate the intermediate plate in thickness, and blind holes, grooves u.
  • support plates e.g. concrete support plates, steel sleepers, reinforced concrete sleepers
  • Form with the bottom consists essentially in that at least some of the recesses on their bottom have projections with a smaller height than that of the corresponding recesses, the cross-sectional area the projections are less than that of the recesses, measured parallel to the contact surface of the intermediate plate.
  • the projections provide additional resistance when the intermediate plate is compressed, starting with a certain load, which then limits deeper deflection, while at the same time the formation of the projections leads to premature destruction of the intermediate plate due to excessive deformation, for example overextension of the edges and subsequent tears can be avoided.
  • the protrusions match the shape, e.g. B. circular in cross section, the recesses, a deformation of the recesses and the projections can take place such that no friction occurs between the inner wall of the recess and the outer wall of the projection, or that friction maxima between these walls can be avoided, thereby premature Destruction is particularly easy to stop.
  • the projections have recesses at their free ends, there is another characteristic in the resistance under load, with two points of discontinuity when deflected with a load, which at the same time can also lead to particularly good sound insulation, since different media are used to transmit the Serve sound, and the enclosed in the cavity Air is a poorer sound conductor than the rubber-elastic material, which comes to rest, for example, along an annular surface.
  • the projections are tapered only in their free end area, a slight increase in resistance is only required when the free end area is deformed, whereas a uniform increase in resistance is required in the event of further deformation.
  • the projections have different heights and their free ends are at different distances from the support surface, then different deformation resistances can be achieved particularly easily, even if the recesses are formed identically.
  • the recesses seen transversely to the longitudinal direction of the rail, have the same height, and the projections in the area under the rail head are less than on both sides of this area, it can be achieved in that the rail is in a secure position in the intermediate plate, whereby through the Limitation of the deformation by the projections the service life can be kept particularly high.
  • the service life of the intermediate plate can be kept particularly high, since preferred deformation regions can be avoided.
  • the support plate 1 partially shown in section in FIG. 1 is constructed with concrete and has steel reinforcement.
  • a recess is provided in this support plate, in which the releasable fastening means are arranged.
  • the rail 2 has a head 3 and a rail foot 4.
  • the rail base in turn rests on an intermediate plate 5 made of soft elastic material, for example rubber, polypropylene, polyethylene, polyurethane and the like.
  • a plate 6 made of steel is arranged below this intermediate plate, which in turn rests on an intermediate plate 7, which is also made of one of the rubber-elastic soft materials mentioned above.
  • the rails are fixed in position via angle guide plates 8, which have a projection 9, as a result of which their position is fixed in the support plate.
  • the plate 6 made of steel, the other intermediate plate 7 are screws, u. between.
  • the rail nail with tension clamps is shown in the drawing only in the left part, but is also provided in the right part in normal traffic with rail-bound vehicles.
  • the support plate 1 which releasably carries two rails, the length of which is a multiple of the track width, lies on the ground over a plastic-elastic mass, the subsurface itself also being constructed with concrete.
  • the intermediate plate shown in FIGS. 2 and 3 corresponds to the intermediate plate 5, which comes to lie immediately below the rail foot 5.
  • Grooves 12 are arranged uniformly transversely to the longitudinal direction of the rails and, as can be seen in FIG. 3, only reach up to half the thickness of the intermediate plate 5.
  • Projections 13 are provided in these grooves, the outer shape of which corresponds to the inner shape of the grooves. However, these projections do not extend to the contact surface 14 of the intermediate plate.
  • the cross-sectional area of the projections 13 as a whole is smaller than the free cross-sectional area of the grooves 12, so that the projections 13 are provided on all sides at a distance from the grooves 12. At their free ends 15, the projections have a surface which runs parallel to the contact surface 14.
  • the intermediate plate shown in FIGS. 4 and 5 corresponds to the intermediate plate 7 on which the rail rests via the steel plate 6 and intermediate plate 5.
  • openings 16 are provided through which the rail nails 10 and on the other hand parts of the angle guide plate are passed.
  • Blind holes 17 are evenly distributed in this angular guide plate 8.
  • the edge of the intermediate plate is free of blind holes.
  • the blind holes 17 have a circular cross section and, as can be seen particularly clearly in FIG. 5, extend only over part of the thickness of the intermediate plate.
  • projections 13 Centrally in these blind holes 17 are projections 13, which have the shape of a cylinder and are evenly spaced from the inner surface of the blind holes.
  • the free end 15 of the projections 13 is formed plane-parallel to the bearing surface 14 and ends in front of this.
  • the projections 13 and the blind holes 17 are each identical, so that the suspension behavior when the intermediate plate is loaded transversely to the longitudinal direction of the rail is completely identical.
  • Both the intermediate plate 7 and the intermediate plate 5 can have a wide variety of recesses, blind holes and. Like. or have projections.
  • the projection 13a is accordingly cylindrical or a cube
  • the projection 13b cylindrical with a truncated cone or as a cube with a roof-shaped attachment
  • the projection 13c as a flattened paraboloid of revolution or prism with parabolic side surfaces in cross section.
  • the projection 13d as a truncated cone or as a prism with a trapezoidal cross section.
  • the projections 13e and 13f correspond to the projections 13a and 13c and have a part-spherical recess 19.
  • the projection is circular in cross section
  • the projection is prismatic, an elongate recess is provided which is partially circular in cross section.
  • the flanks 18 of the recess 17 are not normal to the support surface 14, but inclined at an angle ⁇ of 45 °. Due to this inclination of the flanks, a progressive spring action under load can also be achieved.
  • FIG. 7 shows a rail in the region of the curve of the track superstructure.
  • A means outside of the rail and I inside of the rail.
  • the rail 2 has a plane of symmetry S.
  • This causes an asymmetrical loading of the rail, which can be compensated for by the increase in the elasticity of the intermediate plate 5 or 7 from the inside of the curve to the outside of the curve. Movements of the rail head can thus be avoided, so that the tracks have a particularly good tracking ability.
  • This different deformability of the intermediate plates can be achieved in that Areas of greater deformability, the projections are at a greater distance from the support surface than in areas of lower deformability.
  • the grooves or projections can also be of different shapes, for example in a zigzag shape, in plan view, the distances between the grooves not having to be of uniform design, but also of increasing or decreasing design.
  • areas of particularly good deformability for example areas with a higher proportion of grooves than adjacent areas or areas with protrusions which are at a greater distance from the support surface than other areas.
  • the diagram shown in FIG. 9 schematically shows the increase in the force required to deform the plate.
  • the characteristic curve a corresponds to a plane-parallel plate made of rubber-elastic material with recesses without projections.
  • Curve b corresponds to curve a up to point S 1, from which deflection path the projections are also subject to deformation.
  • the curve c has two discontinuities, u. between S2 and S3, which are obtained by designing the projections according to 13b, e, f, or two different heights of the projections can be provided, so that they are at different distances from the contact surface.
