Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping structure such that water supply pipes and hot water supply pipes for a unit bath can be easily installed and inspected from the indoor side.

[0002]

2. Description of the Related Art When a system bathroom is provided in a 2 × 4 (two-by-four) structure house, since the house is a wooden frame structure, the space obtained between the pillars is closed by a wall panel. Therefore, there is not enough space between the side wall of the bathroom and the wall of the building for piping such as water supply pipes and hot water supply pipes. It was necessary to form the above and arrange these pipes in this space. For this reason, conventionally, an opening is provided in the bottom of the floor pan of the system bathroom, a water supply pipe and a hot water supply pipe are erected in the opening, and a lid made of the same material as that of the floor pan is used (for example, Japanese Utility Model 4- 7256).

[0003]

However, the above-mentioned prior art has the following disadvantages. When the lid is made of the same material (or plastic) as the floor pan, there is a problem of water leakage because the lid and the rising portion of the pipe cannot be sufficiently watertight. The material of the lid is not so flexible. Particularly, in Japanese Utility Model Publication No. 4-7256, since the penetrating portion of the pipe is flush with the floor pan, if the drainage port is clogged and the floor pan is slightly overfilled with water, water may leak. There is.

It is an object of the present invention to provide a unit bath piping structure in which construction and inspection of pipes having different thicknesses can be easily performed from the inside of the room and there is no fear of water leakage.

[0005]

In order to solve the above problems, the present invention provides a waterproof floor pan with a bathtub installation section and a washing room,
In a unit bath in which pipes such as water supply pipes and hot water supply pipes have been started up through openings provided in the bathtub installation section, the openings are covered with waterproof rubber packing, and the holes provided in this waterproof rubber packing are started up to make pipe penetrations. Was provided, the pipe was passed through this pipe penetration portion, and the pipe and the pipe penetration portion were joined with a hose band to seal.

[0006] Further, the pipe penetrating portion is set up for a long time.

[0007]

According to the above invention, the opening provided in the bathtub installation portion of the waterproof floor pan is covered with the waterproof rubber packing, and the hole provided in the waterproof rubber packing is raised to provide the pipe penetrating portion. Since the pipe is passed through the part and the pipe and the pipe penetrating portion are joined and sealed by the hose band, the pipe can be watertightly attached to the pipe penetrating portion of the waterproof rubber packing regardless of the thickness of the pipe.

Since the pipe penetrating portion is erected for a long time, the connecting portion between the pipe penetrating portion and the pipe by the hose band comes to a position apart from the bottom surface of the waterproof floor pan.

The waterproof floor pan 2 is provided with a bathtub installation portion 6 and a washing space 7 with a boundary portion 5 projecting like a wall in the central portion as a boundary.
A bathtub 8 is installed in the bathtub installation portion 6, and the height of the bathtub 8 is adjusted by legs 9. The floor surface of the washing place 7 is formed in a downward slope toward the boundary portion 6, and the washing place 7 facing the boundary portion 5 is provided with a drain port (not shown) and is covered with a perforated plate 10.

A counter 11 is provided on one wall panel 4 side facing the washing space 7, and a hot and cold water mixing plug 12 is attached. The hot and cold water mixing valve 13 is also provided on the edge 14 of the bath 8. A drainage port 15 is provided at the bottom of the bathtub 8, a drainage pipe 16 from the drainage port 15 is arranged in a gap s between the bathtub 8 and the waterproof floor pan 2, and drainage is covered with a dish 10 of the washing place 7. It connects to a drain pipe from the mouth and drains to the outside.

A hot water supply pipe 17 and a hot water supply pipe 18 connected to the hot and cold water mixing tap 13 are straightly erected from an opening 19 provided in the waterproof floor pan 2 directly below the hot and cold water mixing tap 13. A rectangular frame 20 serving as a base is adhered to the outer peripheral portion of the opening 19 in a watertight manner, and the frame 20 is covered with a waterproof rubber packing 21.

FIG. 3 is a plan view of the waterproof rubber packing.
The waterproof rubber packing 21 has a rectangular shape in plan view, and has pipe penetrating portions 22 and 22 penetrating the water supply pipe 17 and the hot water supply pipe 18.
It has.

FIG. 4 is a side sectional view of the waterproof rubber packing, in which the edge portion 23 of the waterproof rubber packing 21 is held by a rectangular frame-shaped packing holding plate 24, which is subjected to a watertight treatment with silicone or the like and the frame 20 is fixed by a screw 25. Fixed to. The pipe penetration 22 is
The waterproof rubber packing 21 is formed by standing up in two cylindrical shapes. The pipe penetrating portion 22 is raised for a long time, and a hole 26 is provided in the upper end portion thereof, and the water supply pipe 17 or the hot water supply pipe 18 is penetrated through the hole 26.

A seal 27 is made of silicone or the like between the inner peripheral portion of the pipe penetrating portion 22 facing the hole 26 and the water supply pipe 17 and the hot water supply pipe 18, and the pipe penetrating portion 22 is exposed from the outside to the hose band 2.
Then, the pipe penetrating portion 22, the water supply pipe 17, and the hot water supply pipe 18 are connected together.

The rectangular frame 20 is watertightly adhered to the outer peripheral portion of the opening 32 as a base, and the opening 32 is covered with the waterproof rubber packing 21.

A water supply pipe 33 and a hot water supply pipe 34, which are horizontally piped in a space q below the washing room 7, are passed through the two pipe penetrating portions 22, 22 of the waterproof rubber packing 21. Similar to the first embodiment, a seal 27 made of silicon or the like is provided between the inner peripheral portion of the pipe penetrating portion 22 facing the hole 26 and the water supply pipe 17 and the hot water supply pipe 18, and the pipe penetrating portion 22 is connected to the hose from the outside. Band 2
Then, the pipe penetrating portion 22, the water supply pipe 33, and the hot water supply pipe 34 are connected together (see FIG. 4). The water supply pipe 33 and the hot water supply pipe 34 are vertically raised by a bent pipe 35 and connected to the hot and cold water mixing plug 13. In addition, 36 is a drainage port.

[0019]

Since the present invention is configured as described above, it has the following effects. According to claim 1, the opening provided in the bathtub installation portion of the waterproof floor pan is covered with the waterproof rubber packing, the hole provided in the waterproof rubber packing is raised to provide the pipe penetration portion, and the pipe penetration portion is provided. Since the pipe is passed through and the pipe and the pipe penetrating portion are joined and sealed by the hose band, the pipe can be watertightly attached to the pipe penetrating portion of the waterproof rubber packing regardless of its thickness. In addition, the piping can be easily installed from the unit bus side.

According to the second aspect of the present invention, since the pipe penetrating portion is erected for a long time, the pipe penetrating portion and the pipe connecting portion by the hose band come to a position apart from the bottom surface of the waterproof floor pan. Even if a small amount of water accumulates in the pan, there is no risk of water leakage.
