Claims

[Scope of claims for utility model registration] A pair of weir plates 1, 1 facing each other, and the weir plate 1
, 1, a plurality of vertical supports 2 arranged in parallel and in contact with each outer surface of the vertical supports 2, a pair of parallel horizontal supports 3 arranged in parallel and in contact with each outer surface of the longitudinal supports 2, both weir plates 1, 1 and concrete 11. and a formwork consisting of a plurality of metal rods 5 that pass through between each pair of horizontal supports 3, and a retaining plate 6 that abuts the outer surface of each pair of horizontal supports 3 to which the metal rods 5 are screwed. On the other hand, an inner vertical portion 7 is inserted vertically between the weir plate 1 and the pair of horizontal supports 3 and is brought into contact with the inner surface of the pair of horizontal supports 3.
An outer vertical portion 7c is connected to the upper end surface of a, and one end of a scaffold support portion 7b that projects horizontally outward perpendicular to the weir plate 1 is connected to the lower surface of the scaffold support portion 7b, which is brought into contact with the outer surface of the pair of horizontal supports 3. are vertically connected, and the tip of the scaffold support portion 7b and the outer vertical portion 7 are connected vertically.
A circular through hole 4 with a cutout groove 4a is provided, which is formed by passing a reinforcing portion 7d diagonally between the lower end of the lower lateral support member 3a, and horizontally penetrates the outer vertical portion 7c from the outside. When the L-piece handle portion 8c of the detachment prevention pin 8 with an L-shaped projecting piece 8c that can be inserted and removed is inserted in a non-hanging direction, and the handle portion 8a is set in a hanging position in the inserted position. An angular steady plate 9 is constructed so that the protruding piece 8c is at a position offset from the notch groove 4a, and contacts the upper lateral support member pair 3a at the inner portion where the scaffold support portion 7b and the outer vertical portion 7c intersect. Scaffold support fittings for assembling and dismantling concrete formwork.
