(B) Since the floor can be constructed simply by attaching a floor plate mainly for production in a factory between the opposing cloth foundations, the construction period can be greatly reduced, and the improvement of construction quality such as level requires a skilled worker. And can be easily constructed.

(C) By omitting the use of wood for the floorboard, the occurrence of corrosion and torsion due to moisture can be prevented, and the need for a moisture-proof sheet to be laid in the fabric foundation is eliminated.

(D) The floor panel is integrated with the heat insulating material, so that the airtightness and the heat insulating property are enhanced, and energy savings and cost reductions can be achieved by reducing cooling and heating costs.

(E) By integrating the heat insulating material into the floorboard, the weight is reduced, and the workability is greatly improved.

(F) Since floor boards are mainly produced in factories, the quality can be made uniform.

(G) It is not necessary to construct a slab or the like in the cloth foundation, and a highly accurate floor can be constructed.

(H) The finishing material is integrated into the formwork at the factory, and by adjusting the hardware set on the cloth base,
The level accuracy of left, right, up and down is improved, and a high quality floor can be constructed.

(I) Since the pre-stress is introduced into the concrete in the mortar injected into the formwork by the tension of the PC steel wire, the floor having excellent strength is formed by the synergistic effect of the PC steel wire and the pre-stress. Can be built.

(J) Conventionally, it was difficult to form a seismic isolation device because there were shackles and large underposts under the floor plate.
Even if the cloth foundation of the floor plate vibrates, the vibration of the floor plate can be greatly reduced by the method of hanging the C steel rod.
