Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is used to maintain a good living environment by suppressing noise and vibration generated from a bubble bath when installing a bubble bath in an apartment complex, etc. The present invention relates to a vibration isolating device for a bubble bathtub that can be effectively used.

<Prior Art> In recent years, bubble baths have become rapidly popular in detached houses, some hotels, sports clubs, etc. However, in so-called collective housing such as apartments and condominiums, the noise generated by bubble baths, Because the problem of noise caused by vibrations propagating to the upper and lower floors or to neighboring rooms has not been resolved, they are not yet widely used.

<Problems to be Solved by the Invention> As mentioned above, there are problems with noise and vibration when installing a bubble bathtub, and if a conventional bubble bathtub is installed as is in an apartment building, noise and noise will be transmitted through the frame to the upper and lower floors and neighboring rooms. Vibration propagates. In particular, the impact on the lower floors was significant, and this was a problem that could not be solved by consideration of the architectural plan alone.

The present invention has been proposed in view of the above situation, and can maintain an acoustically good living environment by reducing noise and vibration generated from bubble bathtubs, and can be installed in apartment complexes, etc. It is an object of the present invention to provide a vibration isolating device for a bubble bathtub.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the present invention installs the bubble bath on a heavy vibration-proof pedestal, and installs the same vibration-proof pedestal on the base via a vibration-proof member. It is characterized by this.

<Function> In the present invention, since the bubble bathtub is installed on the heavy vibration-isolating frame as described above, the vibration-isolating member has no effect on the vibration-proofing member when the bathtub is empty or when it is filled with water.
Furthermore, the change in weight relative to that during bathing can be reduced. Therefore, in any of the above cases, the change in the amount of deflection of the vibration isolating member becomes small, and the vertical behavior of the bathtub becomes small. As a result, noise and vibration from the bubble bath can be effectively reduced.

<Example> An example of the present invention will be described below based on FIGS. 1, 2, and 3.

In this embodiment, it is assumed that the entire bathroom is waterproofed with an asphalt waterproof layer.

In Figure 1, 1 is the concrete slab of the building, 2 is the asphalt waterproof layer, 3 is the holding concrete, 4 is the anti-vibration rubber, 5 is the anti-vibration pedestal, 6 is the rubber pad, 7 is the bathtub, and 8 is the washing area. The pump is placed separately as shown in Figure 2.

Here, the heavier the vibration-proof pedestal 5 is, the more
It has a vibration-proofing effect and is effective in reducing the vertical behavior of the upper circumference of the bathtub when water and human loads are applied. For this reason, we created a cross-sectional shape that can increase the weight of the frame as much as possible by making only the part directly above the installation point of the vibration-proof rubber 4 thinner, and also used concrete 10 as a type of formwork for the bread-shaped box 9, which was made of stainless steel to prevent rust. It is formed by filling. This vibration-proof frame 5
The planar shape of the bathtub 7 is determined according to the shape of the bathroom and is not particularly limited, and the bathtub 7 is installed above it.

In addition, the anti-vibration pedestal 5 has anti-vibration rubber 4, which is placed at 6 to 8 locations based on the shape of the center of gravity, and is made of highly water-resistant rubber, and has an approximately S-shaped structure to reduce lateral vibration. The elements are arranged alternately so that the elastic modulus in the vertical and horizontal directions is equal.

Further, the vibration-proof rubber 4 is not installed directly on the waterproof layer 2, but is installed on the holding concrete 3 so that the load is not concentrated locally.

Further, rubber pads 6 are bonded to the sides of the vibration-proof frame 5 at several locations as cushioning materials during horizontal shaking. In the above-mentioned vibration isolating device, in order to effectively exhibit the vibration isolating effect, the equipment piping connected to the bathtub 7 must be insulated with a flexible joint or the like, and the drain pipe etc. must not cross the vibration isolating frame 5. If it is unavoidable, the pedestal frame will be reinforced and the concrete part will be made into a boxed structure.

In such a structure, the vibration and noise of the bathtub due to the operation of the bubble pump and the ejection of bubbles are suppressed by the vibration isolating frame 5.
Since the vibration is attenuated by the action of the vibration isolating rubber 4, the propagation to the concrete slab 1 can be significantly reduced.

Therefore, there is no vibration or noise propagation to the upper or lower floors or to neighboring rooms, making it possible to safely install the bubble bathtub even in apartment complexes.

Also, since the weight of the vibration isolating frame 5 is increased,
The rate of change in weight when the bathtub is empty, when it is filled with water, and when it is bathing can be reduced, and therefore the amount of deflection that occurs in the vibration isolating rubber 4 in each of the above cases can be reduced. Therefore, the vertical behavior of the bathtub 7 becomes smaller,
The installation condition is stable and a constant vibration isolation effect can be obtained. In addition, some commercially available bubble bathtubs have a bubble pump fixed to the bathtub, and in this case,
The bathtub and bubble pump are installed integrally with the above-mentioned vibration isolator. However, if the bubble pump is installed separately,
As shown in FIG. 2, the bubble pump 11 is installed on a vibration-proof pedestal formed by filling a stainless steel bread-shaped box 13 with concrete 14, and the vibration-proof pedestal 12 is connected to the vibration-proof pedestal 12 via a vibration-proof rubber 15. A soundproof box 18 is installed on the base 16 for anti-vibration support, and a soundproof box 18 made of a sound absorbing material 17 such as glass wool pasted on the inner surface is installed on the base 16 to absorb and block the sound of the bubble pump itself. This makes it possible to reduce noise and vibration isolation generated from the separately placed pump itself.

Figure 3 compares the vibration isolation acceleration levels when the bubble bathtub is vibration-isolated and supported by the above-mentioned vibration-isolating device and when no vibration-isolating device is provided. On the other hand, an example in which anti-vibration support is not provided is a case where a bathtub and a bubble pump are respectively installed on a slab without providing an anti-vibration pedestal. This confirms that the provision of the anti-vibration pedestal achieves a significant vibration reduction effect.

<Effects of the Invention> As is clear from the above, according to the present invention, since the bubble bathtub is supported in a vibration-proof manner through a vibration-proof stand and a vibration-proof member, the noise and vibrations generated by the generation of bubbles can be effectively reduced. can be reduced. Therefore, it is possible to install a bubble bathtub even in an apartment complex without worrying about disturbing the upper or lower floors or neighboring houses.

In addition, since the anti-vibration pedestal has a large weight, even if water or people enter the bathtub, the amount of deflection of the anti-vibration member can be reduced to provide anti-vibration support, which reduces the vertical movement of the bathtub and helps maintain a stable installed state. can be achieved.
