摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a box column, which can reduce deterioration of a material for a skin plate, caused by welding, and the box column.
SOLUTION: In this manufacturing method for the box column, the four skin plates (steel plates) 1 are combined together in a box shape of a square cross section, and fillet welding 3 is applied to the adjacent skin plates 1 from the inside, so that the box column (four-side box column) 2 for a building structure can be manufactured. In the fillet welding 3, an end of the skin plate 1 does not require groove working. Thus, since welding heat input can be reduced, thermal effect exerted on the skin plate 1 can be reduced, and a decrease in the strength and toughness of the skin plate 1 can be suppressed.
