PILLAR STRUCTURE WITH MULTI FLANGE

摘要

PURPOSE: A columnar structure having a multiple flange is provided to enhance the productivity and constructability of an H-section steel column and to accurately deliver normal load of upper and lower columns. CONSTITUTION: A columnar structure having a multiple flange comprises an upper H-section steel column(10), a lower H-section steel column(20), and a joint member(30). The upper H-section steel column is composed of a pair of outer flanges(11a,11b) and a web. The web connects the outer flanges. The lower H-section steel column is arranged in the lower part of the upper H-section steel column. The lower H-section steel column is composed of a pair of outer flanges, an inner flange, and a web(27). The inner flange is formed in the inner side of the outer flanges. The web connects the outer flanges and inner flange. The joint member connects the upper and lower H-section steel columns.
