も防止しているのである。 In addition, since a leg 11 for positioning that maintains the distance from the bottom of the formwork is formed hanging from one of the hook pieces 7, the horizontal reinforcing bar 13 is placed in such a way that the tip of the leg 11 is brought into contact with the bottom of the formwork. and vertical reinforcing bars 14 are fitted and held,
This is effective when used to maintain the distance from the bottom of the formwork, and when pouring concrete, the weight of the concrete is applied to the legs 11 and the hooks 7, 7a are pushed upward. As a result, the horizontal reinforcing bars 13 are further pressed against the vertical reinforcing bars 14, and the cross-contact state between the horizontal reinforcing bars 13 and the vertical reinforcing bars 14 becomes firmer, so that impact forces such as when pouring concrete are reduced. Furthermore, since the hook pieces 7 and 7a are supported by the legs 11, the hook pieces 7 and 7a are damaged by the impact force during concrete pouring, and the horizontal reinforcing bar 13 falls off. It also prevents them from doing so.
