2. Description of the Related Art Conventionally, as for structural load-bearing walls in a frame structure of a wooden building, bracing has generally been used to impart horizontal stress resistance to the wall portion. Therefore, in recent years, attempts have been made to attach structural face materials.
For example, the structural plywood may be nailed and fixed to horizontal beams such as beams, beams, girder bridges, and foundations, and vertical beams such as columns and studs. There is an assembling method in which a structural plywood is nailed and fixed to a receiving material which is nailed and fixed to a horizontal shaft assembly such as a difference or a base, and a vertical assembly such as a pillar or a stud. 5 (Notification No. 1100 of the Ministry of Construction on June 1, 1981, Notification No. 1897 of the Ministry of Construction on November 26, 1990).
