Title: Interlocking components and assembly system

Abstract: A structure for use in structural, load bearing construction is made from cold rolled shapes and/or shaped from structural grade sheet metals or structural shapes. The structure includes interlocking box trusses containing core members held by four web members in perpendicular alignment and pairs of parallel spaced chord members as well as facing units. Each web member and each chord member has a plurality of alternating, tapering, and projecting teeth and transverse strikes on transverse edge faces and at least one of the opposing primary faces. Each projecting tooth has a shape of a truncated pyramid with a taper on three sides of an inverted trapezoid base and with orthographic projection of a greater side, and has facets joined with at least one primary face at obtuse angles, a distance between the facets at the juncture with the primary face being less than at other respective facets. Chord members are aligned and interconnected with respective chord members of adjacent box trusses. Web members interlock with pairs of interconnected parallel spaced chord members at upper and lower transverse edge faces and with pairs of other interconnected web members of adjacent aligned box trusses at side transverse edge faces. The before mentioned facing units are deformed by wedges between the facing units and anti-compression rigid frame core members. Members are locked together in groups of three and form hollow polyhedron shaped and aligned box trusses.
