Abstract

A device for connecting together elongated construction materials has one or more end-surface connecting parts each for being connected to an end surface of one of the materials and a side-surface connecting part for receiving and being connected to side surfaces of another one of the materials. Each end-surface connecting part has a bolt-accepting hole formed for allowing a bolt to pass through and a counter-bored part formed on the reverse side for receiving therein the head the bolt. The side-surface connecting part has an indentation for accepting therein and being connected transversely to another of elongated construction materials. Bolts are passed through holes in the side-surface connecting part to securely attach it to side surfaces of this another elongated construction material.
