Description

The present invention relates to a vibration-proof structure and construction method of the pool, and more particularly to anti Fu構Concrete pool it is possible to reduce the vibration propagating from the pool installed in the building to the building.

  Conventionally, various structures for installing a pool in a building are known (for example, Patent Document 1). In such a structure, it is required to reduce the solid sound transmitted to the building by swimming or jumping in the pool and to suppress the generation of noise outside the pool. In order to respond to this requirement, a vibration-proof rubber is installed between the building slab and the bottom of the pool to support the pool, and the bottom of the pool is placed on glass wool laid on the slab. A so-called floating floor structure is used. Also, even in a general structure that does not use anti-vibration rubber, etc., laying foamed styrene or the like on the bottom of the pool can provide some anti-vibration effect. A support member that is disposed in contact with the side surface of the pool is installed.

JP-A-7-62907

However, the former anti-vibration structure has a disadvantage that the support structure is complicated and the labor required for the construction tends to increase, and the cost burden required for pool installation increases. Further, in the former floating floor structure, a piping space is required around the pool, and the structure of the frame is complicated, which increases the labor for construction.
Furthermore, in the latter general structure, the support member becomes a sound bridge, and the vibration in the pool propagates from the side surface of the pool to the slab through the support member, so that sufficient anti-vibration performance for the outside of the pool is obtained. Inconvenience that it disappears.

[Object of invention]
This invention has been proposed in view of such disadvantages, and its object is a simple structure, the pool that can suppress propagation of vibrations to the building by the use of the pool proof Fu構granulation Is to provide.

In order to achieve the above object, the present invention provides a vibration isolating structure for a pool that includes a bottom surface portion and a side surface portion standing on the outer peripheral side of the bottom surface portion to form an internal space capable of storing water.
Wherein on the bottom inner surface side and side surface portion inner surface side, with contact with the water storage water, attaching a vibration-proof material comprising a foamed elastic body having continuous air bubbles, it is employed configuration that.

  According to the present invention, the simple structure for attaching the vibration isolator to the inside of the pool enables the vibration isolating effect to be obtained not only on the bottom surface side but also on the side surface side of the pool. Even if it is used, it can be avoided that it becomes a sound bridge. As a result, it is possible to suppress the generation of noise outside the pool when using the pool such as swimming while achieving simplification of the structure and reduction of construction labor.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

1 is a schematic cross-sectional view of the installation structure of the pool according to the implementation embodiments the building schematizes is shown. In this figure, a pool 10 is installed on a slab S, and the slab S is oriented in a substantially horizontal direction to constitute a building such as a predetermined building or a sports facility. The pool 10 includes a bottom surface portion 11 and a side surface portion 12 rising from the outer peripheral side of the bottom surface portion 11 to form an internal space capable of storing water.

  Sand 14 is laid on the upper surface of the slab S, and the bottom surface 11 of the pool 10 is placed on the sand 14. On the slab S, a support member 15 attached to the outer peripheral surface of the side surface portion 12 is provided, and the lateral displacement of the pool 10 is suppressed by the support member 15. On the slab S, a housing portion C made of concrete or the like is erected outside the support member 15.

On the inner surface side of the bottom surface portion 11 and the inner surface side of the side surface portion 12, an anti-vibration material 17 having elasticity is attached over substantially the entire area. The vibration isolator 17 is in contact with the stored water and is formed in a board shape or a sheet shape having a predetermined thickness. As the material, a foamed elastic body can be exemplified, and among the closed cells and the open cells, the open cells Is adopted. This is because the open cell can be expected to increase the vibration energy that is attenuated by the viscous resistance through which the internal water flows during deformation.

Therefore, according to this implementation form, it can be attenuated by vibration-proof material 17 vibration of water caused by the use of the pool P. Therefore, it becomes difficult for vibration to propagate not only to the pool P but also to the support member 15, and as a result, vibration transmitted to the slab S or the like can be suppressed, and the vibration-proof performance for the downstairs and the adjacent room can be improved. In addition, the vibration isolator 17 can be retrofitted to the existing pool P, and the vibration isolation can be improved by inexpensive and simple construction.

The best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this.
That is, the present invention has been particularly shown and described with respect to particular embodiments, but is not limited to the embodiments described above without departing from the scope and spirit of the present invention. Various modifications may be made by those skilled in the art in terms of position, orientation, and other detailed configurations.
Therefore, the description limited to the shape disclosed above is an example for easy understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded one part or all part is included in this invention.

For example, the vibration isolator 17 may have a structure in which one piece is provided for each of the bottom surface portion 11 and each side surface portion 12, or a plurality of vibration isolation materials 17 are combined at a predetermined interval along the surface direction.
Further, the vibration isolator 17 is preferably attached to substantially the entire area of the bottom surface portion 11 and each side surface portion 12, but as long as the support member 15 is not a sound bridge and vibration propagation to the building can be suppressed, the anti-vibration material 17 It is good also as a structure which abbreviate | omitted material 17 partially and reduced the contact surface to a building .
