The fixed washer of the predetermined length is integrally attached to the fixed support center, but the center of the fixed support forms a connection hole, and the fixed support tip forms an extended end with an enlarged outer periphery. I'm doing it,

The problem of the above-mentioned application is as follows.

First, there is an excess of cost, which is an economic problem because the gap holder and the coupling portion is made of separate parts,

Secondly, it is also uneconomical by providing a separate fixing base to prevent the coupling portion from flowing in the through hole of the formwork plate.

Third, the role of the washer is to prevent the deformation of the formwork, but there is a question about the effect of the washer,
