The reinforcing member 13 is an approximately L-shaped member. The reinforcing member 13 comprises a first connecting part 15a, which is connected to the connecting surface of the beam 9b of the column 5, and a second connecting part 15b, which is connected to a surface perpendicular to the surface to which the beam 9b is connected. That is, the connecting part 15a and the connecting part 15b are perpendicular to each other. A concave surface part 17 is provided on the inner surface side of the intersection of the connecting parts 15a and 15b. The reinforcing member 13 is, for example, made of steel having excellent weldability. On the connecting parts 15a and 15b, groove parts 19 are formed on the parts corresponding to the welding parts of the column 5.
