Because of the manufacturing reason, the internal structure of the mold beam is such that the laminated member of the vertical portion is bent in the horizontal direction at the position where the upper and lower horizontal portions and the vertical portion connecting the upper and lower horizontal portions are orthogonal to each other and is laminated with the horizontal member. A wedge-shaped space is created in this portion. When a very large tension acts on this joint portion, peeling, scratches, etc. occur from the wedge-shaped space. Therefore,
To withstand this, it is necessary to take measures to reinforce this part.
As a concrete reinforcing measure, an insert piece made of fiber or fiber reinforced plastic is inserted into the wedge-shaped space formed in the joint portion, and the insert piece is bonded and / or sewn to form an I-shaped beam (horizontal member and vertical member). It was firmly attached to the (member). Conventionally, for example, an insert piece having the following structure has been proposed.
