Next, set long horizontal reinforcing bars on the reinforcing bar holding hooks, arrange them in a grid pattern with the vertical bars, fix both ends of the horizontal reinforcing bars to the columnar reinforcing bars, and arrange the reinforcing bars. complete. After that, the wall formwork is installed and concrete is poured.

In the present invention, the above-mentioned reinforcing bar bars manufactured in advance and reinforcing bar supporting members of a predetermined length in which a large number of yers (for holding reinforcing bars) are provided at predetermined intervals are arranged vertically and alternately between the column reinforcing materials. Fix the ends of the bars and the connecting parts between the reinforcing bars, then set the long horizontal reinforcing bars on the hooks for holding the reinforcing bars, arrange them in a lattice shape with the vertical bars, and then There is also a construction method in which both ends of the same reinforcing bars are fixed to the stud reinforcements and the reinforcement is completed. After that, the formwork for the wall was installed and concrete was poured.
1 is there.

In the present invention, reinforcing bars made in advance at a factory are arranged horizontally between two pillars, so there is no need to mark the locations where the reinforcing bars are arranged with chalk, etc. as in the past. It disappears. In addition, it is possible to reduce the work required to tie the reinforcing bars at their intersections, improving work efficiency and standardizing the work.

In the present invention, a reinforcing bar support material of a predetermined length with a large number of hooks for holding reinforcing bars provided at predetermined intervals is vertically fixed to the connection part of the parallel reinforcing bars, and the horizontal reinforcing bars are held in place. It is designed to be set on a hook, arranged in a lattice pattern with the same vertical reinforcements, and fixed. Therefore, it is not necessary to mark the locations where the reinforcing bars are arranged in advance with chalk or the like.
f.

In addition, the reinforcing bars set on the reinforcing bar holding hooks do not shift, so the reinforcing bars can be arranged accurately as designed. Furthermore, since the reinforcing bars do not shift, the coating can be held accurately.
