Definitions

  • the present invention relates to the field of resiliently supporting rails of a railway track, such as for trains, underground, trams, etc.

  • the assembly includes a concrete block adapted for fastening the rail on the top of the block.
  • This assembly further includes a concrete tray extending below and spaced from the bottom of the block as well as around and spaced from the lower region of the peripheral wall of the block.
  • a resilient material such as sold under the trade name Corkelast, has been poured during manufacture of the assembly between the concrete tray and the block. Upon polymerisation (while maintaining its resilient property) the resilient material adheres to the concrete block and concrete tray and thus bonds said tray to the block.

  • the present invention provides a method according to claim 1.
  • at least one of the bottom wall and the side wall of the resilient tray member, preferably the bottom wall as well as the side wall, is manufactured as a sandwich type wall by providing a plate of resilient foam material having an inner face and an outer face, and by providing anchoring sheet portions having a 3-dimensional open structure, at least open on an outer face of said sheet, and by securing said anchoring sheet portions respectively on said inner face and outer face of the plate of resilient foam material.
  • This method e.g. allows to manufacture at a first production location, e.g. in a company specialized in manufacturing of resilient railway support products, a shipment of bottom walls and side walls of the tray member from plates and anchoring sheets.
