Definitions

  • the invention relates to a slab track for rail-bound traffic, as described in the preamble of claim 1.
  • This carriageway has a track grate, the sleepers of which are vertically movable by means of dowel-like devices, but are anchored practically immovably in the sleeper axis on the support plate of the carriageway.
  • the invention has set itself the task of further developing a slab track of the type described above so that the economic disadvantages of the previously required special rail fastening are eliminated.
  • the limited possibility of deflection of the rail on the sleeper with the standard rail fastening is to be expanded by the more economical feasibility of larger spring travel with the help of spring elements arranged under the sleeper.
  • the storage of the track grate according to the invention achieves a safe vertical deflection of the track, which has considerable advantages over the previous solution with deflection directly under the rail foot and is considerably more economical.
  • the solution according to the invention is only possible with a vertically overall elastic or freely moveable mounting of the threshold on the base layer, as is known, for example, in the case of the slab track known from EP 0 637 645, in which the dowels of the sleepers on the base layer also have vertical movements the threshold allows relative to the base course.
  • the vibrating mass By moving the spring from the rail foot to the sleeper base, the vibrating mass is increased by the sleeper mass. The vibration is damped faster and noise emissions are reduced.
  • the threshold can be statically dimensioned with smaller dimensions and / or less reinforcement by punctiform, direct transmission of the vertical track load from the rail to the base course.
  • the proposed design of a slab track enables simple, high-precision pre-assembly of the bearings in the sleeper plant during the manufacture of the sleepers. This reduces the effort for height adjustment on the construction site accordingly.
  • Pollyurethane for example, would be suitable as a material for bearings made of elastomer foam, and chloroprene rubber for bearings made of solid material.
  • the bearings can also be designed as composite elements, for example steel plates with vulcanized rubber, as is customary in bridge construction for deformation bearings.
  • the bearings must be set so that they experience a 1-1.5 mm drop under a certain axle load. In the total weight of the directly supported track grating required for the positional stability of the track, sleepers with the previous standard dimensions and a minimum weight of 350 kg / sleeper are required.
  • the stiffness of the bearings under the sleepers can be increased in the direction of the rails towards the sleeper edges.
  • the restoring moments are increased because of the larger inner lever arms (larger core widths of the bearing cross-sections) these are combined into a storage unit by composite panels made of another material, for example steel, which facilitates assembly and also allows protrusions beyond the threshold.
  • Height corrections of the track grate are usually carried out by relining the rail on the threshold.
  • the bearings under the sleepers can also be increased by inserting additional bearing plates.
  • these compensation plates must be made of hard materials such as steel, hard rubber, etc.
  • the ties that have been anchored to the concrete base layer either have to be added to the dowel blocks or replaced with higher dowel blocks.
  • the important equivalence of the proposed slab track with the classic ballast track with regard to airborne noise emission can also be achieved without absorbers placed on the sleepers if the sleepers are ballasted with a damping bulk material (e.g. from recycling material from concrete demolition). In this case, it must be prevented that hard foreign bodies immigrate into the gap between the threshold and the base course, which prevent the threshold from deflecting.
  • the gap around the bearings and dowel elements can be filled with a soft foam that does not absorb water due to the risk of frost (e.g. closed-pore elastomer foam, foam rubber).
  • frost e.g. closed-pore elastomer foam, foam rubber
  • a sleeper 3 with a dowel 24 is held horizontally immovable and vertically movable on the base layer 1 in the sleeper axis.
  • spring elements according to the invention are arranged approximately as a point-shaped bearing 6 of the threshold, approximately in the axis of the rails.
  • the track grate made of sleepers 3 and rails 4 fastened thereon with a rail fastening 5 are placed on the bearings 6.
  • the bearing 6 consists of a plate 7, which in the example shown has anchoring elements integrally connected to it in a wart-like manner.
  • the anchoring elements 8 engage in corresponding recesses 10 on the underside of the threshold 3.
  • the joint 9 between the plate 7 of the bearing 6 with the anchoring elements 8 is closed with a suitable mortar and thereby the plate 7 is connected to the threshold 3 with the correct position and height.
  • This step is expediently already carried out during the production of sleepers in the sleepers factory.
  • With the anchoring elements 8, a positive connection between the plate 7 and the concrete of the sleeper 3 is achieved, which transfers shear forces even if the adhesive joint between the bearing and the sleeper fails.
  • FIG 3 shows an expedient embodiment of the bearing 6 with a plate 11 according to claim 8 with staggered growing force-transmitting cross sections 11/1, 11/2, 11/3.
  • the plate areas depending on their load-bearing cross-sectional areas 11/1, 11/2, 11/3, make different contributions which are inversely proportional to their size, so that the total deformation progressively decreases with increasing load.
  • Figure 2 shows a slab track in which soundproofing elements 12 according to claim 9 are mounted on the sleepers 3.
  • the reduction in the dimension of the threshold 3 by using the weight of the soundproofing elements 12 according to claim 9 is indicated by the length 13 reduced in FIG. 2 compared to the normal threshold length 14.
  • Height corrections of the track e.g. when the support layer 1 settles, it can be achieved in a simple manner by filling the bearing 6 or 23 with bearing supplement plates 15.
  • the plates 15 can have securing strips 16, by means of which the plates are prevented from moving relative to the bearing. 4 shows the example of a bearing with bearing strips 23.
  • a bearing constructed from bearing strips 23 can be combined expediently and to simplify assembly by means of a composite plate 17 to form a bearing unit 18.
  • the sound emission of the track can be reduced in addition to soundproofing elements 12 by filling the compartments 19 between the sleepers 3 with loose bulk material 20.
  • the gap 21 between the base layer 1 and the threshold 3 must be sealed against the ingress of foreign bodies, particularly from the bulk material.
  • a suitable means 22 for sealing the gap 21 can be aging-resistant, closed-pore elastomer foam.
