DESCRIPTION OF THE PREFERRED EMBODIMENTS The cushioning material used for the flooring material for construction used in the present invention may be a fibrous material, but it is preferable to use foaming by extrusion foaming or in-mold foaming or bead foaming. Synthetic resins are industrially advantageous.

The load of the cushioning material is 5 to 100 kg /
The dynamic spring constant at m ² is 1 to 50 × 10 ⁶ N /
By setting m ³ , preferably 2 to 20 × 10 ⁶ N / m ³ , it is possible to effectively reduce lightweight floor impact noise without adding an excessive mass to the upper part of the cushioning material, and is necessary for housing. It is possible to obtain a floor structure having the required load-bearing performance.

Specifically, the dynamic spring constant is 2 to 20 × 10 ⁶
As a method for obtaining a buffer material of N / m ³ , high-expanded polystyrene of 100 times or more is rolled or pressed at a temperature near room temperature to 5 to 20% of the original thickness by a roll method or a press method or a combination thereof. Compression. The time for compression is arbitrary, and it is advantageous to shorten the time industrially, but the optimum condition may be determined in consideration of the degree of thickness recovery and the dynamic spring constant. When the compression load is removed, the thickness recovers to about 30 to 90%, preferably 40 to 80% of the original thickness. It may be used as it is, or may be sliced to a required thickness and used. It can also be cut or cut into various shapes for use.

The flooring material for a building according to the present invention can exhibit its performance not only by the cushioning material alone but also in combination with another material.

A hook type surface fastener is fixed to the lower surface of the cushioning material thus obtained by a method such as adhesion or adhesion. Further, face materials such as plywood, particle board, fiber board, and synthetic resin board, which can be nailed, were fixed to the upper surface of the cushioning material by a method such as adhesion or adhesion, and the panelized floor base material was fixed on a concrete slab. By laying and laying on a fiber sheet having a loop shape and laying a wooden floor finishing material thereon, it is possible to obtain a floor structure that can be easily reformed from a floor substrate.

When the unevenness of the slab surface is large,
Hook-type surface fasteners on both sides and a panel in which a fiber sheet having a loop shape is engaged with the lower surface of the floor base material are laid on a concrete slab via a non-adjustment material such as mortar and self-leveling material. By doing so, it is possible to keep the level of the floor finished surface uniform.

When a tatami mat is used as a floor finishing material, the tatami mat itself has a performance of reducing a lightweight floor impact sound. There is no problem even if using a hook-type surface fastener on the lower surface of the rigid foam synthetic resin plate by a method such as adhesion or adhesion to form a paneled floor substrate, and has a loop shape fixed on a concrete slab By laying them on a fiber sheet and laying a tatami thereon, it is possible to obtain a floor structure of a Japanese-style room that can be easily reformed from the floor base.
