る法枠工用の部材。 The upper L has a hollow rectangular cross section with a square steel pipe as the core material, chamfers are provided on the four peripheral edges at both ends, and multiple bolt holes are drilled on the upper edge surface with a length equal to the long side of the small end surface.
Lower L with multiple bolt holes drilled on the shaped steel and lower edge surface
A T with a slightly shorter abdomen on the back of the side edge of the shaped steel
Weld the upper L-shaped steel, the lower edge of the lower L-shaped steel, and the abdomen of the T-shaped steel to form an I-shaped protrusion, and form the upper L-shaped steel and the lower L-shaped steel of the protrusion. A horizontal concrete block is made by welding the steel back to the end face of the square steel pipe and the wing tips of the T-shaped steel to the inner circumferential side of the square steel pipe, and has a hollow rectangular cross section with the square steel pipe as the core material. A chamfer is provided on the periphery that abuts the chamfer of the horizontal concrete block, a plurality of long nuts are welded to the long side of the inner peripheral edge of the end face of the square steel pipe facing the bolt holes of the horizontal concrete block, and a steel plate is attached to the end face. and a vertical concrete block formed by welding and closing.
