- a pair of reinforcement member 30 can be joined to the same side at the same height.
- the reinforcing members 30 need to be joined in pairs toward both the left and right. In this case, the reinforcing members 30 do not interfere with each other if the width W of the reinforcing members 30 is equal to or less than 1 ⁇ 2 of the total width of the columns 5.
- the beam 7b when the beam 7b is joined to the column 5 in which the curved surface portion 7 is formed in the corner portion, a part of the beam 7b is the curved surface portion 7 of the column 5. Even when it protrudes, the stress from the beam 7b can be efficiently transmitted to the column 5. Therefore, even when the width of the beam 7b is narrower than the width of the column 5 and the beam 7b is arranged eccentrically with respect to the column 5 in the width direction, the beam 7b and the column 5 are not used without using a through diaphragm. Stress transmission can be ensured.
- the tip of the convex portion 33 does not float from the joint surface of the column 5. . Further, by setting the width W of the reinforcing member 30 to 1 ⁇ 2 or less of the entire width of the column 5, even if the two reinforcing members 30 are arranged in the width direction at the same time on the side surface of the column 5, They do not interfere with each other.
- the inner surface of the convex portion 33 is the concave curved surface portion 35, but the portion may not necessarily be a curved surface.
- the inner surface of the convex portion 33 may be a concave surface portion 35a formed by connecting a plurality of straight lines. In this case as well, when the reinforcing member 30 a is joined to the column 5, the concave surface portion 35 a may be prevented from interfering with the curved surface portion 7.
- the inner surface of the convex portion 33 may be tapered.
- the tapered portion may be prevented from interfering with the curved surface portion 7.
