が図られる。According to the present invention, the C-shaped female metal fitting and the H-shaped male metal fitting arranged on the joint surface of the member are wedged to join the joint surfaces of the members. In the wedge-type joint structure, the C-shaped fitting is composed of a pair of L-shaped folding members facing each other, and each of the folding members is fixed to an anchor material formed separately from the folding member. A core is not required for casting metal fittings, maintaining dimensional accuracy and suitable for mass production and cost reduction.

われる。Further, in order to form a C-shaped metal fitting with an L-shaped wedge metal fitting, a pair of L-shaped metal fittings must be assembled with high precision. However, the L-shaped folding material is an anchor member formed separately from the folding material. Since it is fixed, the present invention enables easy and reliable assembly. According to the second aspect of the present invention, when the L-shaped folding material forming the C-shaped female metal fitting is installed in the mold, L is formed on the side surface of the mold by the combination of the T mold and the trapezoidal mold. Since the folding material of the mold is attached, the folding material can be easily and accurately attached.
