[Problems to be solved by the device]

 However, since the reinforcing bars (6) used in the wall form assembly method are bundled and assembled one by one at the site, the finished dimension becomes unstable and the dimension of each arranging position of the reinforcing bar (6) varies. It was large and it was difficult to position the reinforcing bar (6) with a hooking part or a holding part. Also, in order to maintain the overburden thickness, a spacer (13) was required. Moreover, when fixing the form plate (7), one worker is needed on each side of the separator (A), and in order to mount and fix the form plate (7) on the other side. However, the current situation is that it is difficult to insert the separator (A) into the mounting hole without skill. Further, since the horizontal thickness (10), the vertical thickness (11), and the binding metal fittings (12) are heavy and use a large number of members, it is a labor-intensive and labor-intensive work site. Was difficult to store. However, when it is used, there is a problem that it is difficult to secure workers who are both dangerous and strong because they are likely to be caught in their limbs and fall easily into their limbs.

The present invention standardizes and simplifies the work of assembling a wall formwork, and a series of work is performed by a layman and a woman so that the work can be performed safely and quickly. To provide the data.
