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.

Abstract: Assembled structural components, fabricated from cementitious, fibrous, clay, and aggregate materials, have fibers aligned parallel to tensile forces to form a load bearing structure for use in construction. Fiber and cement membrane components hold rigid core parts in the same relationships as membrane components hold organs in animals. These parts force membrane components apart at selected places to tension and protect membrane components from compressive forces. Facing units are interlocked with membrane faces in parallel alignments. A system of ventilating holes and openings prevents damage due to heat.

Abstract: A central supervisor controls a manufacturing process fabricating fibrous, cementitious structural products requiring very small dimensional tolerance, high strengths, controlled reinforcement alignments, multiple undercuts, and complex shapes not possible using casting, forming, or extrusion. The process uses electrical and magnetic fields to align and direct free floating, cement coated, magnetic, and nonmagnetic fibers, filaments, and elongated fragmented particles onto moving shaping devices. These devices have magnetized shaping tool surfaces to receive aligned materials in layers parallel, perpendicular, and angular to shaping surfaces. Controlled materials, cement, setting agents, magnetic fluxes, and electrical charges make possible better bonding of cements with materials and consolidation of nonplastic matrices. Sliding, and rotating shaping tools make multiple undercuts on faces and edges of the products.
