Definitions

  • the invention relates to an angular guide plate which is an element of rail fastening systems that keeps rail fastened to the support in railroad superstructures.
  • Angular guide plates also referred to as guide plates, are one of the basic components of rail fastening systems that are fixing rail to the support, which is usually concrete sleeper or slab element.
  • rail pads and angular guide plates placed between the rail foot and the sleeper are used.
  • the rail foot is clamped to the sleeper by a spring element, usually a properly shaped tension clip, fixed to the sleeper by a dowel or fastening screw, that is inserted into precast through or threaded hole in the concrete sleeper.
  • guide plates are placed, usually made of elastic material, with central opening through which the above-mentioned dowel or fastening screw of the tension clip can passes.
  • the known angular guide plates have an appropriately shaped upper and lower surfaces. There are usually recesses or sockets in the upper part where the arms or middle bend of the tension clip are seated when completely assembled.
  • the lower surface is designed to fit into the recesses in the sleeper or slab plate to ensure that the angular guide plate remains in a fixed position towards the sleeper and the rail foot, fulfilling its primary function which is to prevent transverse displacement of the rail.
  • Angular guide plates are usually placed on both sides of the rail, pressing their front parts against the rail foot so that a rail channel is formed in which the rail is stabilised laterally.
  • Angular guide plate for a railway profile discloses angled guide plate for rail-fastening systems, having a basic body with an upper side and an underside designed for arranging on a railway sleeper.
  • the angled guide plate has a guide region and a supporting region.
  • the guide region and the supporting region extend substantially parallel and adjacent to each another in a direction transverse to a track direction.
  • the upper side and the underside are spaced apart from each another so that thickness of the supporting region is larger, at least partially, than thickness of the guide region.
  • the basic body of the plate is designed to taper substantially in wedge form from the supporting region to the guide region transversely to the track direction and minimum thickness of the guide region is less than 10 mm.
  • angle guide plate for the fitting of a rail on a foundation has a recess serving as a seat for a free end section of a tension clamp if said tension clamp is in the pre-assembly position.
  • the recess surrounds the end section by less than half of its circumference and the transition between the recess and the section of the angle guide plate that follows on from the recess in the direction of the rail is formed to be free of any abrupt change.
  • the angle guide plate may additionally have a rib extending along the contact surface, and the recess is formed into the rib.
