BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor base material to be interposed between a floor finishing material and a floor support material in a waterhouse of an apartment house.

[0002]

2. Description of the Related Art In water facilities such as kitchens, bathrooms, toilets, and washrooms in apartment houses, consider the waterproofing of the floor as a finishing material.
A so-called cushion floor made of PVC foam is often used. The cushion floor is directly laid on a mortar-finished slab or a plywood (concrete panel) stretched on the slab. In this case, the cushion floor itself has anti-vibration properties, but in the actual construction example, when the slab thickness is 150 mm, the floor impact sound level is L-65.
It remained only to the extent that sufficient vibration isolation performance could not be obtained.

For this reason, conventionally, a dry floating floor structure having a double floor, a wet floating floor structure in which a cushioning material such as hard glass wool is embedded in a slab, and the like have been adopted.

[0004]

However, since such a vibration-proof structure requires a large-scale construction, it is costly, and there is a problem that it is difficult to adopt it in a new housing construction work or a simple renovation work. . In addition, repair work not only caused the floor to become considerably higher and the ceiling height to decrease, but also required repairs to doors and other fittings.

The present invention has been made to solve the above problems, and an object thereof is to provide a floor base material which can improve the vibration damping performance of the floor simply and at low cost. It is what

In order to achieve the above object, the invention of claim 1 is a floor base material interposed between a floor finishing material and a floor support material, which is a cushioning material for damping vibrations. To
It is constructed by sandwiching a surface plate on the floor finishing material side and a back plate on the floor supporting material side, and the cushioning material is composed of a plurality of cushioning material pieces which are independent of each other with a gap. .

According to a second aspect of the present invention, there is provided a floor base material interposed between the floor finishing material and the floor supporting material, wherein a cushioning material for damping vibrations is used as the surface plate and the floor supporting material on the floor finishing material side. It is characterized in that it is formed by sandwiching the back plate on the material side, and a plurality of long grooves extending in the edge direction and / or the longitudinal direction are formed on the surface of the back plate on the floor support material side.

According to a third aspect of the present invention, there is provided a floor base material interposed between the floor finishing material and the floor supporting material, wherein a cushioning material for cushioning vibration is provided on the floor finishing material side surface plate and the floor supporting material. The backing plate on the material side is sandwiched, and the cushioning material is divided into a plurality of cushioning material pieces independent from each other by a gap extending in the foremost direction and / or the longitudinal direction. It is characterized in that it is divided into a plurality of back plate pieces independent from each other by a gap extending in the longitudinal direction.

[0009]

According to the structure of the first aspect of the present invention, the cushioning material for cushioning vibration is sandwiched between the surface plate on the floor finishing material side and the back plate on the floor supporting material side. Thereby, the vibration applied to the floor finish can be buffered, and the surface plate does not impair the feeling of walking.
Further, by the back plate, it is possible to avoid an unexpected situation such that the cushioning material is not damaged or peeled off at the time of construction, and mortar or the like is attached to the cushioning material to reduce the vibration isolation performance. . On the other hand, since the cushioning material is composed of a plurality of cushioning material pieces that are separated from each other with a gap, the cushioning material can suppress the rigidity of the entire body to a low level and narrow the vibration transmission path. In addition, it is possible to disperse, and it is possible to obtain a vibration damping performance that is higher than the designed vibration damping performance of the cushioning material itself. Therefore, the entire structure can be thinned accordingly.

According to the structure of claim 2, similarly to the above,
The cushioning material improves vibration damping performance, the front surface plate provides a walking feeling, and the back surface plate improves workability. Also in this case, the surface of the back plate on the floor support material side,
Since a plurality of long grooves extending in the edge direction and / or the longitudinal direction are formed, the rigidity of the back plate, that is, the rigidity of the entire floor base material can be kept low, and the vibration damping performance can be improved as a whole. . Therefore, the entire structure can be thinned accordingly.

According to the structure of claim 3, similarly to the above,
The cushioning material improves vibration damping performance, the front plate provides a feeling of walking, and the back plate improves the construction.
Further, in this case, the cushioning material is divided into a plurality of cushioning material pieces independent from each other by the gap extending in the forehead direction and / or the longitudinal direction, and the back plate is formed by the gap extending in the forehead direction and / or the longitudinal direction. Since the back plate is divided into a plurality of mutually independent back plate pieces, the rigidity of the back plate can be further reduced, and the vibration damping performance, particularly the vibration damping performance in the low range, can be improved. Further, the cushioning material and the back plate can be easily divided by making a linear cut with a cutter or the like.
