Method for manufacturing a resilient rail support block assembly

摘要

A rail support block assembly includes a resilient member and a molded block having a top, a bottom and peripheral wall. The block is adapted for fastening one or more rails on the top. The prefabricated resilient member has an outer tray and inner tray arranged within the outer tray, and includes a resilient intermediate structure between the trays. The block is molded in a block mold into with the moldable material is introduced and allowed to harden. The block is fixed in the inner tray to extend under the bottom of the block and along a lower region of the peripheral wall. The resilient member may form a part of the block mold, so that a mold member combined with the resilient member delimit the mold for the block. The moldable material is introduced and adheres directly to the inner tray of the prefabricated resilient member.

1. A resilient rail support block assembly adapted to be embedded in or mounted on a railway substructure, said block assembly comprising:
a moulded block having a top, a bottom and peripheral wall, said moulded block being formed of a hardened mouldable material and being adapted for fastening one or more rails on the top of said block;a prefabricated resilient member having an outer tray, an inner tray arranged within said outer tray, and a resilient intermediate structure comprising a layer of elastomeric material disposed between said outer and inner trays, wherein at least said inner tray includes at least one sheet of a 3-dimensional open structure having interstices, and wherein the moulded block is fixed in the inner tray such that the inner tray extends over the bottom of the moulded block and along at least a lower region of the peripheral wall of the moulded block and the hardened mouldable material is entered into said interstices of at least the inner tray.
