COMPOSITE STEEL JOIST/COMPOSITE BEAM FLOOR SYSTEM AND STEEL STUD WALL SYSTEMS

摘要

The present invention provides metal stud perimeter wall and load-bearing wall systems that support without eccentricity, concrete-topped floors on open-web steel joists, deep-profiled composite metal decks, and channel-shaped joists, and allow upper floor framing to be completed before Boor concreting; a composite steel beam, for open-web steel joist support; a new shear-connection-ready open-web steel joist; and a perimeter metal stud wall system that incorporates an in-wall wheel stopper. The wall systems incorporate web-perforated studs, and/or web-perforated tracks doubling as concrete closures, and other concrete closure devices. The composite beam incorporates shear connectors protruding through a special web-perforated track fitted with a load-bearing, block and cut-outs in the legs for open-web steel joist support. Unlike, composite open-web steel joists supporting simple-span metal decks, the shear-connection-ready joist incorporates a fiat-topped chord to allow continuous steel deck layout and field-installed shear connectors. These joists are best used with, medium-depth wide-fluted composite floor deck for maximum system efficiency.
