Definitions

  • the invention relates to a cross-section for railway tracks made of concrete, reinforced concrete or steel, such as are used in connection with track gratings resting on a ballast bed in the railway superstructure.
  • the cross sleeper as a component in the railway superstructure absorbs the forces from the traffic loads via the rail and the intermediate layers with the tensioning elements in the support points of the sleeper supports and the forces introduced are distributed to the underlying ballast structure and distributed to the substructure or underground.
  • the concrete sleeper and the comparable steel sleeper in this context have the disadvantage that, in contrast to the wooden sleeper, two non-elastic materials meet on the support surface of the sleeper on the ballast, so that the above-mentioned toothing is not possible, so that the inclusion of longitudinal - And lateral forces is reduced by the ballast bed.
  • the hard, inelastic lead Contact points between ballast and sleeper in the event of excessive stress to damage or destruction of the sleeper or ballast.
  • the invention is therefore primarily based on the object
  • cross sleeper is provided on its underside, in particular in the region of its supports, with a plastically deformable coating.
  • the plastically deformable coating can consist essentially of a tar / asphalt mixture, which is a particularly economical solution.
  • the coating can consist essentially of a plastic, wood-concrete, wood or wood chips.
  • plastically deformable coating exclusively in the region of the support of the cross sleepers, so that the support-free zones remain uncoated.
  • the thickness of the coating can be comparatively thin, i.e. are less than 10mm and can in particular be about 5mm. Furthermore, the underside of the coating can be profiled in order to achieve an even better anchoring of the cross sleepers on the ballast bed.
  • the coating of the cross sleepers according to the invention can optionally also be applied subsequently to the sleepers, it is preferred to integrate the application of the coating into the manufacturing process of the concrete sleepers in order to ensure the best possible bond.
  • the coating can be applied to the corresponding areas of the underside of the threshold, in particular as a final operation when casting the threshold.
  • the coating could also be subsequently glued to the underside of the threshold.
  • the drawing shows: 1 shows a vertical section through a track in a plane parallel to the rails,
  • FIG. 2 shows a top view of the track according to FIG. 1,
  • FIG. 3 shows a horizontal section through the track according to FIG. 1 perpendicular to the longitudinal direction of the rails
  • Figure 4 is an enlarged sectional view in the area of a threshold.
  • reference number 10 denotes a ballast bed
  • reference number 12 transverse sleepers arranged in the ballast bed
  • reference number 14 rails arranged on the cross sleepers
  • reference number 16 a wheel guided on the rails.
  • the usual intermediate layers 18 are arranged between rail 14 and cross sleepers 12.
  • the ballast bed 10 lies on a flat surface 20.
  • this structure of a railroad track corresponds to the conventional structure and requires no further explanation.
  • Plastically deformable coatings 22 are formed on the undersides of the cross sleepers 12, specifically, as can be seen from FIGS. 2 and 3, in such a way that the support-free regions 24 of the cross sleepers 12 are free of coatings.
  • the hatching in FIG. 2 is intended to indicate those areas of the underside of the threshold (not visible in FIG. 2) on which a coating is provided.
  • the arrows 26 and 28 in Figures 1 to 3 are intended to indicate the transverse or longitudinal forces occurring in the track.
  • the detail representation according to FIG. 4 illustrates the interlocking of the stones of the ballast bed with the plastically deformable coating 22.
