Description of the Related Art Conventionally, as shown in FIG. 5, a method of mounting an earthquake-resistant slit is to fix one of joint materials to be attached to both ends of a slit material to the inside of a wall form by nailing at the time of formwork. A slit material is attached to the joint material, and a support arm, which is attached to an appropriate position of the separator and attached to maintain a space between the wall forms, is attached and fixed to a backing plate attached to one side of the slit material. Next, the other wall form in which the joint material to be attached to the other of the slit members is nailed at a predetermined position inside is previously erected so that the slit material and the joint material can be attached, and the wall mold is formed. It was attached to the frame. Also, as in Japanese Patent Application Laid-Open No. 08-93266, a predetermined strength is provided by attaching a reinforcing material to the slit material, and the supporting materials attached to both ends of the slit material are sandwiched between the wall forms and attached. Things are also disclosed.
