LEGISLATION METALOGISTS AND FRAMEWORK SYSTEMS

摘要

The lightweight metal construction system begins with a beam (2) formed from a single piece of cold formed sheet steel or other sheet metal which is bent lengthwise along four lines to form a triangular cross section with two wings (4, 6), side-by-side, extending from its apex. The ends of the beams may be modified to form joints which are used to connect two beams together or to connect the beam to another construction material. Brackets (20) formed from strips of sheet steel or other metal are bent to conform to outer surfaces of the beams or other construction materials are used to attach the beams to other beams or other construction materials. Fasteners (40) are used to firmly attach the joints and brackets to the beams and construction materials.
