Definitions

  • the invention relates to a cross tie for railway tracks made of concrete, reinforced concrete or steel, such as those related to one Ballast bed overlying rail gratings can be used in the railway superstructure.
  • the cross sleeper as a component in the railway superstructure takes that of the forces arising from the traffic loads via the rail and the intermediate layers with the tensioning elements in the bases of the sleeper supports and the forces introduced are applied to the underlying ballast structure derived to distribute the load and passed on to the substructure or subsurface.
  • the concrete threshold and those in it Similar steel tie the disadvantage that, in contrast to Wooden sleeper, on the support surface of the sleeper on the gravel two inelastic materials meet, so that the above-mentioned toothing is not possible, so that the absorption of longitudinal and transverse forces by the Ballast bed is reduced. Furthermore, the hard, inelastic lead Contact points between ballast and threshold in the event of overuse Damage or destruction of the sleeper or ballast.
  • the invention is therefore primarily based on the object To create a threshold with which the positional stability of the track can be increased and damage to the ballast bed is avoided at the same time.
  • the underside of the threshold is due to the plastic deformation of the coating achieved a "interlocking" of the threshold with the ballast, which on the one hand Transverse sliding resistance and the longitudinal sliding resistance of the track grate is significantly increased and thus the positional stability of the track is significantly improved becomes. Furthermore, this ensures that, on the one hand, peak pressures are reduced and Edge pressures are reduced and on the other hand that the contact area between the ballast and threshold is increased so that the surface pressures be reduced compared to the prior art and material destruction be reduced or excluded. After all, the one with the Coating achieved "softness" of the contact area between ballast and Threshold gentle on materials.
  • the plastic deformable coating consisting essentially of a tar / asphalt mixture exist, which is a particularly inexpensive solution.
  • the coating can essentially consist of a plastic, of wood concrete Made of wood or wood chips.
  • plastic deformable coating only in the area of the support Form cross sleepers so that the bearing-free zones are uncoated stay.
  • the thickness of the coating can be comparatively thin, i.e. under 10mm lie and can in particular be about 5mm. Furthermore, the Underside of the coating to be profiled in order to anchor the Achieve cross sleepers on the ballast bed.
  • the coating of the cross sleepers according to the invention can also be attached to the sleepers, if necessary it prefers to apply the coating in the manufacturing process of the Integrate concrete sleepers to ensure the best possible bond.
  • the coating can be used in particular as a final operation Pour the threshold onto the corresponding areas of the underside of the threshold be applied. Alternatively, the coating could also subsequently glued to the underside of the threshold.
  • reference number 10 is a ballast bed with which Reference number 12 transverse sleepers arranged in the ballast bed, with the reference number 14 rails arranged on the cross sleepers and with the reference number 16 Inscribed wheel guided on the rails. Between rail 14 and Transverse sleepers 12, the usual intermediate layers 18 are arranged.
  • the Ballast bed 10 lies on a formation 20. In this respect, this structure corresponds of a railroad track the conventional structure and requires no closer Explanation,
  • FIG. 4 illustrates the interlocking of the Stones of the ballast bed with the plastically deformable coating 22.
