Fastening for flat metal component e.g. rail plate to concrete support such as sleeper uses polymerizing liquid and layer of expanded metal

摘要

The fastening consists of an expanded metal layer (4) welded to the under surface of a metal component such as a rail plate (1) to create an open structure with projections and recesses, and a liquid product (RE) which is applied between the metal component and concrete support (P) and polymerizes to fix them together by adhesion.
