TEMPORARY FLOOR, FRAMEWORK FOR SUPPORTING SUCH A FLOOR, AND STRUCTURAL MEMBERS CONSTITUTING SUCH A FRAMEWORK

摘要

Organs channel-shaped rolled mild steel, preferably reinforced by pressed grooves (9 and 10) and preferably having lips facing inwards (11) and the edges of the lips turned down (12) may be attached by welding (a) mouth to mouth to give a vertical framework supporting box-shaped section and (b) back to back to provide a horizontal beam-shaped section I. The bodies may also be used simply as side horizontal beams. A mezzanine floor and similar structures of temporary support can be constructed using such welded unitary organs (to obtain a solid modular framing attractive appearance), and suitable interconnecting members are also disclosed.
