Claims

[Scope of utility model registration request]

One end of the main body with a protrusion formed on one side of the vertical member and a contact surface for the weir plate are provided on the opposite side of the protrusion, and the other end of the main body and the tip of the protrusion are fitted with a Type 3 tightening washer. It is formed on the joint surface with the engagement recess, and the length between the abutting surface on the longitudinal side of the main body and the joint surface is the sum of the thicknesses of the vertical flap material and the horizontal flap material, and the length in the protruding part direction. The length between the side abutment surface and the joint surface is made equal to the thickness of the horizontal side material, and a protrusion that fits into the tightening washer is formed on both joint surfaces, and is clamped on the main body. For a concrete formwork tightening washer, the clamping portions are provided with upwardly open mounting grooves that alternately face the longitudinal direction of the main body and the direction of the protrusion and are removably fitted to the tightening rods.
