Column fixing metal member, method for manufacturing column fixing metal member, and building

A method for manufacturing a column fixing metal member, the column fixing metal member including a first plate, a support portion, a second plate, and a coupling portion configured to be coupled to a column, the method comprising:

• temporarily fixing the second plate and the support portion to each other;
• firstly welding the support portion and the first plate to each other in a state in which the support portion is temporarily fixed to the second plate;
• secondly welding the second plate and the support portion to each other;
• and
• thirdly welding the coupling portion to the second plate;
• wherein the support portion includes:
• a first end surface in contact with an upper surface of the first plate;
• a side surface intersecting the first end surface;
• and
• a first boundary line that is a boundary between the first end surface and the side surface,
• the first boundary line includes a first boundary region,
• the second plate includes a cutout portion including a cutout edge,
• the cutout edge of the second plate includes a first cutout region,
• in the temporary fixing the second plate and the support portion to each other. the second plate is temporarily fixed to the support portion in a state in which the second plate is disposed on the support portion such that the first cutout region of the cutout portion extends along the first boundary region of the first boundary line, and
• in the firstly welding the support portion and the first plate to each other, a portion of the support portion including the first boundary region is welded to the first plate such that a welding rod of a welding tool is aligned along the first cutout region.
