Definitions

  • the present invention relates to a device for fixing running rails on a support structure.
  • the rail support can comprise a support plate or a support cross member on which the fasteners, also called clips, clamps, or even toads are arranged so as to hold the rail in position.
  • the rail is commonly composed of a lower part or shoe which rests on the rail support, of a central part or web, vertical which connects the lower part to an upper part.
  • the upper part has a running or circulation head for a vehicle.
  • the clip To hold the rail, the clip generally comes to bear on the top of the shoe by means of a tab projecting towards the rail.
  • the binding may alternatively, or in addition, bear against the outer edge of the shoe to constitute a lateral stop for positioning the rail.
  • the clips are bolted and / or welded to the rail support.
  • the commonly used fasteners comprise a base welded to the support and an upper part forming the rail retaining flange, removably attached to the base.
  • the fasteners are anchored to the mounting bracket by means of bolts. Bolted fasteners are easier to disassemble but are not suitable for supporting loads as high as welded fasteners.
  • the clip comprises a body from which extends a retaining tab provided with an elastic pad (also called a nose) coming into contact with the upper face of a shoe of a rail.
  • the body comprises an oblong opening which allows the passage of a fixing bolt, while allowing an adjustment of the body in translation relative to the lateral face of the rail, in order to limit the lateral displacement of the rail.

  • the washer is a separate part, there is a risk of losing it during transport.
  • the elastic pad (or nose) remains a fragile part, sensitive to operating conditions: rain, salt, UV, temperature. The clips are therefore often replaced during track maintenance campaigns because the elastic bush (or nose) is worn.
  • the object of the present invention is to provide an improved fixing device for fixing a rail on a support structure which does not have the drawbacks of known fasteners.
  • the device according to the invention also comprises positioning means making it possible to adjust the position of the body relative to the rail when the fixing member is engaged through the body, in particular in the through passage.
