Definitions

  • the invention relates to a railway sleeper with underside coating or soles by means of a composite plate.
  • underside coatings of elastic materials are applied in the manufacturing process during concreting or adhesively bonded to the underside of railway sleepers.
  • an elastic plastic or rubber layer is already coated during production with a grit spread, which allows a connection to the concrete in the production of concrete sleepers.
  • Other methods prefer profiling in the decking with concrete-adhering properties.
  • DE-A-4 315 215 moreover, proposes to additionally arrange a geotextile layer on the underside of the elastic plastic layer facing away from the concrete body. This arrangement serves to protect the elastic plastic layer against the ingress of ballast points and thereby damage to the plastic layer and not the bond between concrete sleeper and elastic plastic layer.
  • a geotextile layer on the underside of the elastic plastic layer facing away from the concrete body.
  • the threshold partially enclosing elastic profiles are not identical with soled thresholds in the context of this invention.
  • An object of the invention is to provide a method for shear force-resistant connection of a railway sleeper concrete body with at least one underside of the concrete body arranged elastic Kunsstoff für with a ballast bed, the soloing of which can be easily realized manufacturing technology and permanently elastic.
  • the design, manufacture and application of threshold solders excluding the aforementioned disadvantages, is achieved in that the sleeper sole consists of a multi-layered construction using a needled nonwoven fiber material and in particular a geotextile and at least one elastic plastic layer with defined properties.
  • Nonwoven materials and in particular geotextiles surprisingly have excellent adhesion properties to fresh concrete and at the same time plastic and elastic properties.
  • this property can be adapted to the requirements.
  • the fibers are suitable for thermal bonding with elastic plastics.
  • These plastics in turn, can be adapted in surface hardness, elasticity and strength to the requirements of the threshold soling.
  • microforming that is the coupling or mechanical connection of the at least one elastic plastic layer or in the case of several elastic plastic layers of the sandwich structure of these layers on or with the concrete body by the fibers of the nonwoven layer, leads to extremely high tear and shear strengths, which ensure the lasting hold of the elastic plastic layer on the underside of the concrete body, even with the dynamic loads typical of railway sleepers.
  • the fleece layer ensures a frictional material pairing between concrete and plastic.
  • the demolition resistance of the plastic plate of the concrete body increases decisively, which is due to the fact that due to the nonwoven layer, the connection between the plastic plate and concrete is insensitive to shear forces and vibrations, as it were a flexible connection of the plastic plate is given on the threshold.
  • the geotextile is welded to the plastic material of the plate or at least the fiber ends of the web are embedded in the material of the plastic plate, the concrete penetrates during casting of the threshold partially in the nonwoven layer, so that it after curing of the concrete to a mechanical entanglement the fibers come in the near-surface concrete layer.
  • another (plastic) random fiber nonwoven material can be used.
  • the soles 10 are inserted in concreting concrete sleepers 12 in the formwork.
  • the sole 10 consists e.g. from a 3 mm to 5 mm thick elastic plastic layer 14 with a defined spring index of e.g. 200 kN / mm.
  • a plastic nonwoven layer for. B.
  • a geotextile layer 16 placed on the plastic layer 14 and welded to this production inside taking advantage of the not yet hardened consistency of the plastic.
  • this may also be formed in multiple layers. The welding of the fibers of the geotextile layer 16 with the plastic layer 14 and the embedding of the fibers in the concrete sleeper 12 are not shown in the schematic drawing.
  • the resulting plate then consists of an underside elastic plastic plate and a top side with this frictionally welded geotextillage.
  • the thickness of the geotextile layer is about 3 mm to 10 mm.
  • the composite panel described here (at least one elastic plastic layer and nonwoven layer) will be designed in this embodiment as a coating of the bottom of a concrete railway sleeper.
  • the railway sleeper may be a prestressed concrete railway sleeper or a slack reinforced concrete railway sleeper.
  • the railway sleepers with composite panel can be used for branch or intersection-free track sections or for switches, crossings or intersection deviations.
  • the composite panel is also on the underside of others on a substrate, eg. B. the ground resting concrete body such. As paving stones, walkway or Fahrwegplatten or the like. used. However, these uses of the composite panel do not constitute embodiments of this invention.
