に行われる。According to the soundproof flooring of claim 1, the cushioning material layer comprises:
Since the cushioning material is composed of a plurality of cushioning material pieces which are independent of each other with a gap therebetween, a hollow portion is formed between the cushioning material layer and the other material layer due to the gaps therebetween. The hollow portion propagates the vibration from the other upper material layer (upper layer) to the other lower material layer (lower layer) through the air layer in the hollow portion.

Also, in parts other than the hollow part,
Vibration is propagated from the wide portion of the upper layer to the narrow portion of the lower layer. That is, since the vibration is dispersed and propagated, the transmissibility of the vibration energy in the cushioning material layer becomes small. Further, since the plurality of cushioning material pieces are independent of each other with a gap therebetween, the cushioning material layer does not increase the rigidity of the whole, and the vibrations are well damped as a whole.

Vibration such as shoe noise generated in the base material layer 2 propagates through the plurality of cushioning material pieces 3a, and partly propagates in the slit 4 and propagates to the lower layer. In this case, inside the slit 4 (air layer)
The vibration that propagates through the members propagates between members having extremely different densities, propagates once in the air layer as a sound, and becomes a vibration again in the lower layer (slab or the like). Therefore, it is extremely attenuated. Further, the vibration propagating through the cushioning material piece 3a passes from the wide portion of the base material layer 2 to the narrow portion of the cushioning material layer 3,
Further, it is propagated to a wide portion of the lower layer. Therefore, the vibration is dispersed and propagated through a narrow portion, and the transmission rate of the vibration energy in the cushioning material layer 3 becomes small. That is, the vibration propagating through the cushioning material layer 3 is damped by the material of the cushioning material layer 3 and also by the structure of the cushioning material layer 3.

Since they are independent of each other, the rigidity of the base material layer 2 to which the cushioning material layer 3 is adhered does not increase, and the vibration damping property of the base material layer 2 is not impaired. Therefore, the respective material layers 2 and 3 can be organically combined so as to enhance the vibration damping performance. Although the slits 4 are formed in the fore edge direction and the longitudinal direction in this embodiment, they may be formed in only one of the directions.

In the floor material 1 of this modification, a plurality of grooves 5 are formed on the lower surface of the base material layer 2. The groove 5 extends parallel to the edge direction and the longitudinal direction, and is formed at the same position and with the same width as the slit 4 of the cushioning material layer 3. In this case, after adhering the cushioning material layer 3 to the base material layer 2, a slit is formed in the cushioning material layer 3 by cutting a portion of the base material layer 2 with a cutter (saw tooth). The groove 5 of the layer 2 is formed at the same time.

For this reason, the base material layer 2 itself can be provided with a certain level of vibration damping property, especially in the low range. Further, the slit 4 of the cushioning material layer 3, that is, the cushioning material piece 3a and the groove 5 of the base material layer 2 can be formed extremely easily. In this case, the groove 5 also has the slit 4
According to the above, it may be formed only in one of the edge direction and the longitudinal direction.

In the floor material 1 of this modified example, the groove 5 formed in the base material layer 2 and the slit 4 formed in the cushioning material layer 3 are arranged so as to be alternately displaced in the forehead direction and the longitudinal direction. . Therefore, according to this modified example, the path of the vibration propagating from the base material layer 2 to the lower layer via the cushioning material layer 3 varies widely and is displaced in the forehead direction and the longitudinal direction,
It gets complicated. Therefore, the vibration can be damped more effectively.

6 and the slit 17 formed in the lower cushioning material layer 15 are disposed so as to be displaced in the forehead direction and the longitudinal direction. Therefore, the path of the vibration propagating to the lower layer via the intermediate cushioning material layer 13, the base material layer 14 and the lower cushioning material layer 15 changes widely and narrowly, and is displaced in the edge direction and the longitudinal direction, so that the vibration is more effective. Can be attenuated.
