Composite steel joist/composite beam floor system and steel stud wall systems

摘要

This invention reveals new 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 complete before floor concreting; a new composite steel beam for open-web-steel-joist support; a new shear-connection-ready open-web-steel joist; and a new perimeter metal stud wall system that incorporates an in-wall wheel-stopper. The new 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 cutouts in the legs for open-web-steel-joist support. Unlike composite open-web-steel joists supporting simple-span metal decks, the new shear-connection-ready joist incorporates a flat-topped chord to allow continuous steel deck layout and field-installed shear connectors. The new joists are best used with medium-depth wide-fluted composite floor deck for maximum system efficiency.
