However, in the above-mentioned conventional example, many work steps such as placing a large number of posts in the formwork, placing large pulls and joists (square pipes) on it, and then placing the slab formwork are necessary in the formwork construction. Moreover, handling a long rectangular pipe between the forested posts was extremely inefficient.

Even when demolding, the work procedure is to remove the posts by leaving the minimum required number of posts, knock over the remaining posts to drop the large pull and joists, and peel off the slab formwork attached to the bottom of the slab. The floor surface may be damaged due to such factors as a safety issue.

Also, by using a Peco beam, etc., the number of square pipes and posts used can be reduced, or a special post with a large dish-shaped support member installed at the upper end of the post is forested and a slab formwork is laid directly on it. The method of doing so is also known,
Also in these, as in the above-mentioned conventional example, the support work and the laying of the formwork are performed as separate work steps.When dismantling and removing the formwork, the support work is disassembled and the slab formwork is slab-shaped. It was inefficient because it required a work procedure such as peeling from the bottom surface.
