INTERENGAGEABLE STRUCTURAL MEMBERS |
摘要 |
Structural members (80) having an intermediate web (81) and hollow tubular side flanges (83, 85) extending longitudinally of the web (81) are formed in a cold rolling operation such that one of the tubular side flanges (83) has an outside diameter of the opposite tubular side flange (85). The larger diameter side flange (85) has a longitudinally slotted aperture (87) to permit a composite structure (120) to be formed by nesting the smaller diameter flange (83) in the larger diameter flange (85) of an adjacent structural member (80). The composite structure (120) having a plurality of interconnected structural members (80) may be assembled as a closed or open structure. |
