ABSTRACT:
A structural truss composed of spaced rails interconnected by a series of struts swingably coupled at their ends. Track members on the rails receive the ends of the struts which are slid into place between the rails. Thereafter, the struts are crimped in place upon the rail members to form a load supporting structural member.
In a second embodiment, rivets are slipped into the track members, the struts are slipped upon the rivets and the ends of the struts and the rivets are deformed to form the structural truss.
