常に手間がかかる欠点があった。2. Description of the Related Art Generally, when building a concrete wall, a formwork made of plywood is assembled, concrete is poured into the formwork to wait for hardening, and the formwork is removed to apply various makeups to the surface or In the case of heat insulation walls, construction was performed by the procedure of attaching heat insulation materials. However, in the case of the above-mentioned formwork method, the formwork is used only as a mold for constructing a wall surface, and there is a drawback that the subsequent work of removing the formwork takes a lot of time and effort.

In addition to this, the consumption of natural materials is significant, and their use must be restricted from the viewpoint of protecting the natural environment. From such a viewpoint, a concrete wall form made of fiber reinforced cement has been proposed, and it has been proposed to use it instead of a conventional plywood form (for example, Japanese Patent Laid-Open No. 3-2934).

There was a drawback that required. However, in order to solve such a problem, fixing bolts are planted in a concrete formwork in advance and it is used to fix to a support frame etc., but the position of the bolt cannot be changed. There was a drawback that it was very difficult to deal with dimensional errors on site.
