COMPOSITE BEAM WITH REINFORCED SUPPORT MEMBER STRUCTURE AND THE BUILDING CONSTRUCTION METHOD THEREWITH

摘要

Disclosed are a steel composite beam using a support reinforcing frame which can more effectively ensure the cross-sectional rigidity regarding the installation of the steel composite beam on a pillar structure and a structure construction method thereof. The steel composite beam includes: a pillar member which is rigidly installed on the upper surface of both side ends of lower casing concrete to be spaced apart from the upper surface of both side ends of lower casing concrete in the longitudinal direction; the support reinforcing frame including an upper end connecting member installed between both side surfaces of the pillar member and a steel beam and a vertical side plate detachably installed on the side surface of the pillar member to be used as a mold for floor plate concrete; and the floor plate concrete which is poured into an internal space (S) formed by the support reinforcing frame and the upper surface of the lower casing concrete.
