Abstract
Rigid structural members, profiles, joints, and forms added to structural sandwich panels to provide higher strength, integral joining joint, and single facing sheet manufacturing. Facing sheets (20) and (22), rigid structural members (24) and (26), latch side and pin side cam-locks (34) and (32), fabricated wire truss assembly (48), and rigid structural headers (28) and (30) and an integrated top plate (29) are positioned into containment form assembly (58) in the proper position. Facing sheets (20) and (22) are placed in position in the containment form assembly (58) forming a structural sandwich panel assembly. A foam resin core material (40) is injected into the structural sandwich panel assembly and allowed to cure. The resultant structural sandwich panel includes rigid structural members (24) and (26) and elongated recesses (36) and (38) which also form a joint for joining abutting structural sandwich panels together and cam-locks (32) and (34) used to secure adjoining panels together. Comer and angle panels have a comer rigid structural assembly (44).
