Process for forming a connection interface between metallic or wooden beam and a concrete element, e.g. for bridge, involves forming bed of granules that are fixed to beam by layer of glue

摘要

The process involves forming a bed of granules (3) fixed on a lower face to a top face of a wooden, e.g. plywood, or metallic beam (1) by a layer of glue (4), such as a synthetic resin. The top part of the granules are embedded in the lower face of a concrete element (2), with the granules being encrusted when the concrete is poured on-site.
