Description of the Related Art Heretofore, as a floor material in a middle- and high-rise house, it has been general that carpets are directly attached to a concrete floor through a felt. However, in addition to the fact that carpets are easily soiled, it takes a lot of time to replace them, and furthermore, the occurrence of mites has become a problem.

ば多少改善されるが、それでも十分ではなかった。Therefore, instead of sticking carpets, a method of directly sticking a wooden floor material to a concrete floor has been increasingly used. However, since the wooden floor material is inferior in sound insulation property to carpets, it has a drawback of impairing habitability. In order to solve such a drawback, if a synthetic resin foam is attached to the entire back surface of the wooden board, it is somewhat improved, but it is not enough.

No. 2-69691 (see Japanese Utility Model Publication No. 1-10144)
As a result, we proposed a sound insulation wooden flooring material in which a sound insulation sheet, a vibration damping sheet or a cushioning sheet, a perforated wood board, and a cushioning material were sequentially laminated on the back surface of the wooden board. In the invention of this application, a polyolefin-based foam, a rubber foam, or the like is used as the cushioning material, and among them, the independent foam is used as a preferable one because it is excellent in waterproofness and is less likely to be settled than the continuous foam. ing.

ある。Although the cushioning material of the above-mentioned invention has a considerable amount of sound insulation effect, it has a flat sheet shape and a large contact area with the floor surface. There was a limit to the transmission rate, and further improvement was required from that point. In view of the above-mentioned circumstances, the present invention is to provide a wooden flooring material having more excellent sound insulation.

Disclosed is a sound-insulating wooden flooring material characterized in that a foam cushioning material with hollow protrusions, which is composed of a protrusion and a protrusion having a low expansion ratio and a low degree of expansion, is sequentially laminated. Further, the present invention also discloses a sound-insulating wooden flooring material in which a cushioning sheet is further attached to the back surface of a rubber foam cushioning material with hollow protrusions, and a further cushioning effect is exerted and, for example, a concrete flooring is provided. When it is necessary to attach the floor material to the floor surface with an adhesive, as in the case of direct construction on the floor, the gap between the protrusions of the rubber foam with protrusions is filled with the adhesive and the cushioning effect decreases.

If two sheets are used as shown in FIG. 3 and the holes are shifted and they are bonded together, the sound insulation effect is further improved. As the cushioning material 4, a rubber foam with a protrusion containing butadiene styrene rubber as a main component is used. FIG. 4 shows a plan view of the cushioning material 4 made of this rubber foam with protrusions. The cushioning material 4 includes a protrusion 5 having a high expansion ratio and a soft hollow interior, and a protrusion 6 having a low expansion ratio and a hard eye. Preferably, the cushioning material 4 is configured such that the four sides and diagonal portions of the rhombus are protrusions 6 having a low foaming ratio and a hard eye, and the protrusions 5 having a high foaming ratio and a soft interior are arranged at the intersections of the diagonal lines of the rhombus. It is made up of combinations. The height of the protrusion 5 is higher than that of the protrusion 6.

とができるようになっている。It should be noted that it is possible to arbitrarily carry out a sanding process for removing sand from the surface wooden board and the middle wooden board including the sound insulating sheet to suppress the movement of the surface plywood. The sound transmission can be prevented by the cushioning effect of the hollow portion 7 of the protrusion 5 of the cushioning material 4. In addition, even if the hollow portion 7 of the projecting portion 5 having a high foaming ratio and a soft interior is not received by the load from above, the projecting portion 6 having a low foaming ratio and being hard can receive it. ing.

(Example 2) A floor material was manufactured by further adhering a foam sheet or a nonwoven fabric 8 as a cushioning sheet to the lower surface of the rubber foam with protrusions of the floor material of Example 1 (see Fig. 5). As a foam sheet,
Polyolefin-based foams, rubber foams, and the like are used, and among them, the independent foams are preferable because they are excellent in waterproof property and are less prone to fatigue than continuous foams.

In particular, the lightweight impact sound, such as the sound of slippers, has been improved. Also, in the case of a flooring material in which a foamed sheet or non-woven fabric is further attached to the lower surface of the rubber foam with protrusions, the foamed sheet or non-woven fabric also provides a cushioning effect, and also serves as an adhesive surface when directly installed on a concrete floor. It is possible to prevent the gap between the protrusions of the rubber foam from being filled with the adhesive and reducing the cushioning effect.
