[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration structure for a bathtub, and more particularly to a structure for preventing vibrations in a bathtub such as a unit bathroom from being transmitted to a floor slab.

[0002]

2. Description of the Related Art A conventional bathtub supporting structure is, for example, as shown in FIG.
(See FIGS. 3 (a) and 3 (b)) so that the height of the adjuster bolt 4
Is fixed to the floor slab 5 with the adhesive 7 on the side of the head 4a, and the part 2 where the bathtub is installed and the part 3 where the washing place is installed inside the floor pan 1 are formed by bathers and the like. This may be a source of noise or vibration that is generated, and the vibration or the like may directly propagate to the floor slab 5 via the adjuster bolt 4, and may cause trouble on the downstairs. As a countermeasure, for example, as shown in FIG. 5, it is conceivable to interpose an anti-vibration rubber 6 between the adjuster bolt 4 and the floor slab 5 and receive the vibration from the floor pan 1 with the anti-vibration rubber 6. .

[0003]

By the way, in the vibration-proof structure shown in FIG. 5, in order to fix the vibration-proof rubber 6 to the floor slab 5, it is necessary to cover the whole of the vibration-proof rubber 6 with the adhesive 7. . Therefore, the movement of the vibration isolating rubber 6 is stopped, and the adhesive 7
As a result, there is an inconvenience that the anti-vibration function is impaired.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an anti-vibration structure for a bathtub which can sufficiently exhibit the anti-vibration function of an anti-vibration rubber. It is in.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a floor pan of a bathtub is supported on a floor slab via an adjuster bolt so as to be freely adjustable in height. An anti-vibration material is interposed between the anti-vibration material and the anti-vibration material, a vibration absorbing portion that absorbs vibration from the floor pan, and an adhesive portion that is bonded to the floor slab with an adhesive,
A damming portion which is coupled to the outside of the vibration absorbing portion via a depression and which blocks an inflow of an adhesive from the bonding portion to the vibration absorbing portion.

[0006]

According to the present invention, the vibration isolating material interposed between the adjuster bolt and the floor slab is composed of an adhesive bonded to the floor slab by the adhesive, and an adhesive flowing from the adhesive to the vibration absorbing portion. And a damping portion for damping the vibration damping material, so that the adhesive material coated on the bonding portion of the vibration damping material is blocked by the damping portion and does not flow into the vibration absorbing portion of the vibration damping material. This makes it possible to securely adhere the adhesive portion of the vibration-proof material to the floor slab, prevent the vibration-absorbing portion of the vibration-proof material from being covered with the adhesive, and sufficiently exhibit the vibration-proof function of the vibration-proof material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, a floor pan 1 of a bathtub is supported on a floor slab 5 via an adjuster bolt 4 and an anti-vibration rubber 10. The adjuster bolt 4 is interposed between the floor pan 1 and the vibration isolating rubber 10 to adjust the height of the floor pan 1 with respect to the floor slab 5. Further, the vibration isolating rubber 10 has a vibration absorbing portion 12 that absorbs vibrations and the like from the floor pan 1, and the lower end 7 a of the upper flange portion 11 of the vibration absorbing portion 12 is fixed to the head 4 a of the adjuster bolt 4. ing. A bonding portion 13a bonded to the floor slab 5 by the bonding material 7 extends radially outward from the lower flange portion 13 of the vibration absorbing portion 12, and a vibration is provided on the bonding portion 13a. The vibration absorbing section 1 is provided outside the absorbing section 12 via a depression 30.
An annular damming portion 14 is provided upright so as to be concentric with FIG. 2 (see FIG. 2). The damming portion 14 has a function of blocking the flow of the adhesive 7 covering the bonding portion 13a into the vibration absorbing portion 12 to prevent the vibration absorbing portion 12 from being covered with the adhesive 7. Also, the lower surface 13b of the lower flange portion 13
A projection 15 is formed at the center of the lower surface 13b to form a slight gap G between the lower surface 13b and the floor slab 5, and the adhesive 7 can enter the gap G. Further, the adhesive 7 is applied to the bonding portion 13a of the lower flange portion 13 by the gap G.
A through-hole 16 is formed so that the vibration-proof rubber 10 can be efficiently intruded into the floor slab 5.

Next, when the work is performed, the lower flange portion 13 of the vibration-proof rubber 10 provided at the lower end of the adjuster bolt 4 with the screw portion 4b of the adjuster bolt 4 screwed into the nut portion 1a of the floor pan 1 is screwed. Is placed on the floor slab 5, and the height of the floor pan 1 is adjusted by rotating the adjuster bolt 4. Thereafter, the bonding portion 13a of the vibration-proof rubber 10 is coated with the bonding material 7 made of an adhesive or mortar, and the bonding portion 13a is fixed to the floor slab 5. Here, the adhesive 7 is blocked from flowing into the vibration absorbing section 12 by the blocking section 14, and there is no possibility that the vibration absorbing section 12 is covered with the adhesive 7, so that the movement of the vibration absorbing section 12 becomes free. In addition, the anti-vibration function of the anti-vibration rubber 10 can be sufficiently exhibited.

In this embodiment, since the projection 15 is provided on the lower surface 13b of the lower flange portion 13 of the vibration isolating rubber 10, the contact area between the vibration isolating rubber 10 and the floor slab 5 can be made as small as possible. Thereby, the height adjustment by the rotation operation of the adjuster bolt 4 can be easily performed regardless of the contact area between the vibration-proof rubber 10 and the floor slab 5 and the unevenness of the surface of the floor slab 5. Further, since the projection 15 forms a gap G between the vibration-isolating rubber 10 and the floor slab 5, and the through-hole 16 is provided in the bonding portion 13a, the adhesive 7 covering the bonding portion 13a is removed from the through-hole 16 through the through-hole 16. There is an advantage that the adhesive wraps around the gap G and the adhesive strength between the vibration isolating rubber 10 and the floor slab 5 is further increased.

[0010]

According to the present invention, as described above, the floor pan of the bath tub is supported on the floor slab via the adjuster bolt so that the height can be adjusted, and the vibration proof is provided between the adjuster bolt and the floor slab. The material is interposed, the vibration-proof material is a vibration absorbing portion that absorbs vibration from the floor pan, an adhesive portion that is bonded to the floor slab with an adhesive, and a recess outside the vibration absorbing portion. And a damping portion for damping the inflow of the adhesive from the bonding portion to the vibration absorbing portion, so that the bonding portion of the vibration damping material can be securely bonded to the floor slab, and Can be prevented from being covered with the adhesive, and the vibration-proofing function of the vibration-proof material can be sufficiently exhibited, so that propagation of vibrations and the like to the floor slab can be reliably prevented.
