REINFORCEMENT STEEL BEAM WITH SHEAR REINFORCEMENT MATERIAL

摘要

PURPOSE: A reinforcing steel beam with a shear connection reinforcing material for a slim floor system is provided to achieve structural stability and improved constructability as a bottom plate, a steel beam, and a concrete slab are integrally coupled in a slim floor system. CONSTITUTION: A reinforcing steel beam comprises an improved steel beam(20) and a plurality of shear connection reinforcing materials(30). The improved steel beam includes an upper flange(21), a lower flange(22), a web(23) and a pair of deck plate holders(24). The web, having lower reinforcing bar through holes(25) perforated at regular intervals, is located between the upper flange and the deck plate holders. The shear connection reinforcing materials are vertically welded between the top of the deck plate holders and both ends of the upper flange.
