2. Description of the Related Art Conventionally, in order to construct a floor on a concrete slab in a so-called S-structure, RC-structure or SRC-structure other than a wooden structure, a construction method in which a floor material is stretched on a joist fixed on a concrete slab is called concrete. A construction method is used in which a floor material is stretched over a large slab fixed on a slab, and a construction method is used in which a floor material is stretched over a floor slab standing on a concrete slab. In each of the construction methods, as described above, a joist, a large scale or a floor stake is directly arranged and fixed on the concrete slab surface which is an uneven surface (uneven surface), so that it is very difficult to adjust the floor level.

Therefore, as a construction method for solving the above-mentioned drawbacks,
First, adhesive b is spread or spread over the entire surface of the concrete slab a in order to obtain dust control and adhesive effect, and mortar kneaded and blended on site is piled up or ridged regularly on the surface. A non-woven material c, a styrofoam molded plate e (base material) coated with an adhesive d at a predetermined position on the back surface of the non-woven material c is placed, and the upper surface of the styrofoam molded plate e and the joist f so that the upper surface of f is at the same level, spread the styrofoam molded plate e,
A construction method was developed that simplifies the level adjustment of the floor by laying finish materials g such as floorboards and tatami mats on it, but this construction method is a completely wet construction method, mortar kneading / compounding work, mortar In addition to the disadvantage that the work site is easily contaminated at the time of distributing / transporting work and mortar laying work, the adjustment gap x is formed between the concrete slab a and the styrofoam molded plate e by using the non-woven material c, Even if the unevenness of the concrete slab a can be eliminated and the styrofoam molded plate e can be laid at the same level, it is very difficult to adjust the level, and the styrofoam molded plate must be cured and cured of the non-woven material c. e had the drawback that it was not possible to work on it.

There is also a method of applying a mortar to the upper surface of a concrete slab by using a gold trowel to eliminate irregularities. However, such a method requires manual skill, and even a skilled worker needs to apply a mortar on the mortar surface. It was extremely difficult for the iron wave to remain and to form an accurate horizontal plane.
