Hollow section for panel construction - has round section tenon and mortice formed by extrusion operation

Abstract

Abstract The hollow extruded profiled section is for the construction of panels, being basically rectangular. In the extrusion operation, a tenon of round section (2) with an opening (5) towards the inside of the profiled section (1) is formed along one of the narrow sides of the latter. In the opposite narrow side, the extrusion process forms a mortice (3) of trapezium section, the small base of which forms the mortice opening (4). The round-section tenon can be joined to the profiled section by a straight portion (6), and the mortice opening can be wider than this portion. A boss (7) can be formed at the apex of the tenon, and which, when fitted, extends nearly to the base (8) of the mortice.
