STEEL COMPOSITE BEAM FOR REDUCING STORY HEIGHT, SLIM FLOOR STRUCTURE AND CONSTRUCTION METHOD USING THE SAME

摘要

The invention FHM-saving steel composite beams, providing a slim floor structures and construction methods using the same. upper flange and lower flange; and, it connects the said upper flange and said lower flange, the web a plurality of openings formed by cutting the steel sheet are formed in a longitudinal direction; And, is formed by pouring concrete to be included in the upper surface of the lower flange of the lower flange, the concrete is poured through the opening on both sides of the web is continuous is provided such that the integral, concrete for improving the load bearing capacity of the lower flange part; including, but the web is formed by cutting so that I-beams or H is open downwardly in the opening of the abdomen or steel beams formed, the upper portion of the web is bonded to the bottom of the web openings are formed in the upper flange the steel is joined to the lower flange, wherein the opening is formed to be gradually wider in the bottom flange, the opening, through which space the plant through the pipe portion is formed in the upper side, and the lower space in the concrete part is Composite provides FHM-saving steel composite beams characterized in that the composite is formed. ;
