Definitions

  • the invention relates to a system for fastening a railroad track with a concrete sleeper and an angle guide plate having rail track attachment with the features of the preamble of the patent claims.
  • angled guide plates as components of rail fasteners on concrete sleepers that secure the connection to the threshold as plate-like components on both sides of the rail. They thus serve both to secure the position of the rail on the support surface of the threshold against displacement in the transverse direction of the track and for the transmission of Raddose material in the threshold body.
  • the angle guide plate is secured by friction by the depressing force of a tension clamp.
  • Such fastening systems or concrete sleepers are for example from the WO 2012/167947 A1 known.
  • an angle guide plate is used, in which the material over the entire width of the angled guide plate extending rib is divided into individual projections. These projections are supported against a shoulder in the concrete sleeper, it being understood that this shoulder, as usual in the art, in a running across the width of the threshold groove or bead is trained.
  • a guide plate for laterally guiding a rail and a system for fixing the rail wherein a projection of the guide plate engages in a conventional manner in a correspondingly shaped groove of the threshold. Groove and projection each extend across the width of the threshold or width of the guide plate.
  • a comparable system is known in which the projection is interrupted in the middle by a material thinning or material recess.
  • the threshold has a shape that is designed so that the projection for power transmission can engage accordingly. Again, it can be assumed that this form is a running across the width of the threshold groove.
  • a concrete threshold according to EP 1 384 812 A2 which has a rail support area between the raised shoulders of the threshold, which is substantially flat, that is formed without transversely running, deep beads.
  • the connection between the shoulder and rail foot is provided by guide plates, which are provided in one embodiment with transverse to the threshold Verfitschhöckem, which engage at the outer edges of the Schienenauflagerschens into corresponding recesses in the form of shallow beads.
  • the object of the present invention is therefore to design a system for fastening a railway track with a concrete sleepers and a rail fastening so that on the one hand to retain its previous functions without restriction, but at the same time the utilization of the full threshold height possible without being affected by a bead and thus create economically advantageous solutions for flat sleepers.
  • the invention is based on the idea that according to the prior art across the Threshold continuous bead and thus split the lower rib of the angled guide plate in two areas that are moved as far as possible to the outer edge of the threshold cross-section. In the middle area then the bead and the lower rib can be omitted. This frees up space for a higher wire layer
  • Fig. 1 shows a side view of the angled guide plate according to the invention with the base plate 1, the lower rib 2 and the upper abutment angle 3.
  • the center of the base plate 1 patch stiffening rib 4 improves the transmission of Radtress originally from the base plate 1 in the lateral bearing surface of the abutment angle.
  • the lower rib 2 engages positively in the bead 5 of the threshold and thus secures the Position of the rail on the threshold transverse to the track longitudinal direction.
  • the superimposition of the rail on the threshold is carried out according to the prior art via an elastic intermediate layer 6, which transfers the vertical loads from the rail 7 to the threshold.
  • the Radten technique be passed directly from the rail 7 in the base plate 1.
  • Fig. 2 is the splitting and displacement of the lateral support surface shown.
  • the lower rib 2 with the bead 5 is displaced outward to the edge regions of the threshold cross-section 10.
  • the abutment angle 3, however, runs unchanged over the entire width of the angle guide plate.
  • Fig. 3 For more details on the construction of the angled guide plate will be explained.
  • the trapezoidal outline of the base plate 1 results from the fact that the contact surface of the base plate 1 is taken over unchanged against the rail 7.
  • the length of the abutment angle 3, however, is chosen as large as possible, on the one hand to better distribute the Radten member in the threshold section 10 and on the other hand to widen the middle area with full height for the installation of additional tension wires 8.
  • the length of the abutment angle 3 can also increase due to a greater width of the threshold upper side, which in turn creates more space for further tensioning wires 8.
  • the circular opening 9 located in the base plate 1 corresponds to the prior art. It serves to pass the sleeper screw into the concrete of the threshold cross-section 10.
