CONCRETE FILLED DUAL STEEL TUBE COLUMN

摘要

PURPOSE: A concrete filled dual steel pipe column is provided to simultaneously pour concrete into the inner and outer steel pipes of the concrete filled dual steel pipe column. CONSTITUTION: A concrete filled dual steel pipe column(100) comprises an outer steel pipe(110), inner steel pipes(120a,120b), a joint member(130), and a fixing member(140). The outer steel pipe is filled with concrete inside. The inner steel pipe is filled with the concrete inside. The inner steel pipes are layered inside the outer steel pipe to be separated from each other. The joint member joins neighboring inner pipes among a plurality of inner pipes which are vertically and separately layered. The joint member is arranged to partially open the separated part of the inner pipes. The fixing member is joined to the inner surface of the outer pipe and the outer surface of the inner pipe. The fixing member fixes the position of the inner pipe inside the outer pipe.
