Therefore, when a floor material is directly impacted, it is transmitted through the floor material and the floor of the building. There is a problem that vibration is transmitted to the base material and transmitted to the lower floor, which is not preferable for soundproofing. For example, in an apartment house or the like, there is a problem that if a child runs around on the upper floor, a complaint is made from a lower-floor person.

This makes it more difficult for vibration to be transmitted. Further, the elastic body 5
The upper and lower surfaces of the elastic body 5 have a structure in which vibration is hardly transmitted, and the upper surface of the portion protruding toward the upper surface side of the elastic body 5 is a flat surface. When the floor material is firmly adhered to the substrate 3 and the floor material is conveyed or constructed, the elastic body 5 having upper and lower surfaces which are uneven is not peeled off from the substrate 3. Since the lower end surface of the part projecting to the lower surface side of the elastic body 5 that has become uneven has a downwardly projecting curved surface, the contact surface with the floor base material such as a slab is reduced as much as possible. In addition, even if the floor substrate such as a slab has irregularities, even if the floor substrate has a convex surface even when it hits a convex portion, the convex portion of the floor substrate From the floor base material, such as slabs. It is those that can.

The upper surface of the portion protruding to the upper surface side of the elastic body 5 is flat, so that the flat surface of the upper surface of the elastic body 5 is firmly adhered to the substrate 3 irrespective of the unevenness, and the floor material is transported or installed. In this case, the elastic body 5 having the upper and lower surfaces having irregularities can be made difficult to peel off from the substrate 3. In addition, since the lower end surface of the portion of the elastic body 5 having the upper and lower surfaces that are protruded from the lower surface side is formed as a curved surface that protrudes downward, contact with the floor base material such as a slab is minimized. Reduce the surface, improve the vibration isolation, and even if the floor substrate such as a slab has irregularities, even if the convex portion of the floor substrate hits the curved portion, it is a curved surface, so the floor It can be deformed so as to be easily displaced from the convex portion of the base material, and the unevenness of the floor base material can be absorbed.

である。[Effects of the Invention] In the present invention, as described above, the soft sheet is laminated and integrated on the lower surface of the wooden decorative board, and the substrate is laminated and integrated on the lower surface of the soft sheet. The lower surface of the lower portion of the elastic body having the upper and lower surfaces becomes uneven, and the lower surface of the lower portion of the elastic body has a concave and convex surface and the upper surface of the portion protruding toward the upper surface. Is a flat surface, so by sticking a soft sheet, the resonance of the wooden decorative board can be suppressed, the sound generated when impact is applied to the floor surface can be reduced, and vibration can be damped by the lower elastic body, Furthermore, since the upper and lower surfaces of the elastic body are uneven, vibration is less likely to be transmitted from the elastic body to the floor substrate side, such as a building slab, and a more reliable soundproofing and vibration-proofing effect can be exhibited. And, like this, the elastic body The upper and lower surfaces are made uneven so that vibration is difficult to be transmitted. Since the upper surface of the portion protruding to the upper surface side of the elastic body is flat, the upper surface of the elastic body is flat despite the unevenness. When the floor material is firmly adhered to the substrate and the floor material is transported or constructed, the upper and lower surfaces of the elastic body do not peel off from the substrate, and the upper and lower surfaces of the elastic body have uneven surfaces Because the lower end surface of the part protruding to the side is a curved surface that protrudes downward,
The contact surface with the floor base material such as slab is reduced, and the vibration proof property is enhanced. Furthermore, even if the floor base material such as the slab has irregularities, the convex portion of the floor base material becomes a curved surface. Even if it hits a part, it is a curved surface, so that it can be easily deformed so as to be shifted from the convex part of the floor substrate, and can absorb irregularities of the floor substrate.
