COMPOSITE GIRDER AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A composite girder improving structural capability and a manufacturing method are provided to improve rigidity by improving cross-sectional shape of a beam member. CONSTITUTION: A composite girder comprises flanges(1,2), a web(3), a concrete(5) and a solder bath(7). The flange is extended to the longitudinal direction and is formed at an outer rim of a closed section. The web is connected to the flange in the longitudinal direction. The concrete is charged inside the flange. The solder bath is formed in the web contacted part of the flange in the longitudinal direction.
