Claims

[Claim for Utility Model Registration] A lower end reinforcement is placed horizontally on the base stirrup that constitutes a part of the base reinforcement, a plurality of stirrups are erected on the lower end reinforcement, and an upper end reinforcement is placed horizontally on the plurality of stirrups. A reinforcing unit which is an opening reinforcing bar to be attached to a suspended reinforcing bar structure, the upper end of each of a plurality of vertical bars being shorter than the stirrup bars and each having a horizontal bar suspended at the lower end thereof is suspended and fixed to an intermediate bar; It consists of a pair of substantially S-shaped reinforcing diagonal bars with upper and lower ends of the inclined central part extending in opposite directions and horizontally, and the reinforcing bar unit is replaced with the stirrup at the opening installation position of the reinforcing bar structure. Both ends of the intermediate reinforcement are tied to the stirrup located outside the opening installation position so that the reinforcement unit is attached, and the pair of reinforcement diagonal reinforcement is tilted downwardly. The central part is
Each upper end of the pair of reinforcing diagonal bars is tied to the upper end reinforcement of the reinforcing bar structure so as to face each other on both outsides of the opening installation position to form an inverted V shape, and each lower end is tied to the lower end reinforcing bar of the reinforcing bar structure. Reinforcing bars for openings, each of which is tied together with the pair of reinforcing diagonal bars attached.
