Definitions

  • the invention relates to a device and a method for fastening a rail to a structure.
  • the device and method of this type are used for fastening railroad rails, tram rails or similar to structures, such as sleepers (also called ties or crossties) or a road ground structure.
  • railroad rails comprise a foot, a web and a head.
  • a device of the intended type comprises a baseplate to be fixed to the structure and for supporting the rail, and a fastening element for clamping the foot of the rail to the baseplate.
  • fastening devices for fastening railroad rail to sleepers and other types of structures in the prior art.
  • One such type of fastening devices comprises a baseplate and a fastening element, wherein the baseplate is arranged for supporting the rail and wherein the fastening element is arranged for clamping the rail to the baseplate.
  • the baseplate comprises a support with an aperture for receiving the fastening element, so that an end portion can be inserted into the aperture.
