PURPOSE: A welding beam for a prefabricated building structure is provided to be used for a main member requiring a great internal force by improving local buckling resistance on a beam surface and providing an excellent internal force to a beam. CONSTITUTION: A welding beam (10) for a prefabricated building structure includes a web (30) of which the top and bottom are welded with flanges (20). Reinforcing protrusion parts (31) is protruding from the web at regular intervals. A connection part (30') is formed between the reinforcing protrusion parts. The connection part is positioned in the center of the upper and lower flanges. The reinforcing protrusion parts are alternately positioned on the left and right sides of a connection member. An internal force is improved by reinforcing the web and widening the contact area of the web and the flange. The connection part is made of a flat plate or an uneven plate. |
