(Prior art and its problems) In concrete buildings such as condominiums, the impact on the structure and the resulting vibrations propagate within the structure as solid sound, causing sound to propagate from the upper floor to the lower floor, for example. is the main cause of noise generation. Conventionally, in order to prevent the generation and propagation of such solid sound, a so-called floating floor structure has been adopted in which a finished floor is insulated from the concrete structural floor, but this reduces the floor height of the building and reduces the construction process. However, it also has problems such as being about three times as large as the direct bonding structure.

In other words, when the shear hardness is 70 or less, the L value is 55, which is proposed by the Architectural Institute of Japan as the minimum necessary soundproofing effect for concrete apartment houses, and when the shear hardness is 30 or less, the more preferable L value is 50. It is clear. In addition, in the case of L (fi55), the sound of children's running footsteps is a little bothersome, and in the case of L value 50, the soundproofing level is such that it is hardly noticeable.

From the above, from the point of view of soundproofing effect, the shear hardness of the liquid rubber 14 is 70 or less, preferably 30 or less,
Considering the compression characteristics (pressure ratio 50%) required for architectural interior materials, especially flooring materials, the shear hardness is 1.5 as shown in Figure 4.
It is necessary to use preferably 5 or more of the above.

On the other hand, the anti-FF effect of the above example in which the thickness of the foam 13 was doubled and the liquid rubber sheet 14 was omitted was similarly confirmed as the "L value" by changing the expansion ratio of the polyethylene foam 13. The results are shown in Figures 5 and 6.

The foam 13 and the liquid rubber seal 14 have very similar properties in terms of soundproofing effect. Also, foam 1
3 and the liquid rubber sheet 14, the weight ratio and price ratio are both about 1:10, so it is preferable for the soundproof board material to adopt only the foam 13 and omit the liquid rubber sheet 14. When using the liquid rubber sheet 14 as a flooring material for physical education FF1 etc.,
It is desirable under various circumstances to use the two in a laminated state, since the stress acting on the human feet during exercise is reduced and has a favorable effect on the body tissues. In addition, the specific gravity between both layers is relatively high (1,2~
2) If a Q plate-shaped member, such as a fiberboard, is inserted, mutual interference between the two layers will be prevented, and more effective sound and vibration isolation can be achieved. ” - spread the leveling material,
Alternatively, it is preferable to provide a cushion layer between the concrete floor surface and the lower surface of the flooring material by pasting a so-called uneven material on the lower surface of the flooring material.In this way, in addition to the sound insulation performance of the flooring material itself, Since it can simultaneously prevent the propagation of sound through the void layer that occurs between the highly uneven concrete floor surface and the lower surface of the flooring material, it is possible to obtain a more practical soundproofing effect. .

(Effects of the Invention) According to the wood board material according to the present invention, the liquid rubber layer interposed between the top plates absorbs the impact and the vibrations generated thereby.
