Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a piping device suitable for use in water supply and hot water supply, for example, in a bathroom unit.

[Conventional technology]

Traditionally, bathroom units have been used mainly in mid-to-high-rise residences, and the bathroom unit is fitted into the installation space at the construction site to create a bathroom (see, for example, Japanese Patent Publication No. 8163/1983).
In such bathroom units, the piping for water supply and hot water supply is installed behind the wall, so once the bathroom unit is installed, even if water leaks from the joint of the piping, it cannot be easily repaired. . However, there is a high risk of water leakage at piping connections, and as long as joints exist, it must be considered that there is a risk of water leakage.

Therefore, recently, instead of relying on rigid metal pipes that require joints at bent points, flexible pipes such as cross-linked polyethylene pipes and copper pipes are being used in the form of long bodies that do not have joints in the middle. This flexible tube is piped through a sheath tube which is a protection tube, and water and hot water are supplied through this flexible tube.

[Problem that the invention seeks to solve]

However, even in piping using such flexible pipes, it is necessary to form a joint in the piping section from the wall of the bathroom unit to the inside of the bathroom.
There was a risk of water leaking from the joint located on the back side of the wall. Such water leaks inevitably lead to water leaks in residences, uncleanliness, and corrosion of equipment.

In the above piping system, even if water leaks from the joint located on the back side of the wall, the present invention prevents the leakage from occurring on the back side of the wall and allows the water to leak from the front side of the wall, that is, on the indoor side of the bathroom unit. The purpose is to allow water leakage to escape.

[Means for solving problems]

In the present invention, a joint protection box 7 is provided from the indoor side of the pipe insertion hole 4 of the wall 1, and the pipe insertion hole 4 is provided with a joint protection box 7.
An elastic sheet 12 is provided to close off the elastic sheet 12, and a flexible tube 6 made of a long body is inserted into the insertion hole of the elastic sheet 12. The protection box 7 has a screw tube 8 at the front outside and a connecting tube 11 at the rear inside. The end of the flexible tube 6 is connected to the connecting tube 11 within the protective case 7, and the flexible tube 6 is in communication with a conduit 9 leading to a faucet 17 which is screwed onto the screw tube 8. This relates to a piping device in which a drainage hole 16 is formed in the bottom surface of a protective box 7.

Reference numeral 1 denotes a wall constituting the bathroom unit. The wall 1 has tiles 2 pasted on the indoor side wall, a reinforcing plate 3 is provided on the back side, and a pipe insertion hole 4 is formed in the wall 1. ing. 5 is a sheath tube, and 6 is a flexible tube, and the flexible tube 6 is inserted into the sheath tube 5. The sheath tube 5 has a bellows-like wall surface and is bendable, and is made of, for example, synthetic resin or metal. flexible tube 6
is a pipe body that has excellent flexibility and can be easily bent, such as cross-linked polyethylene pipes and copper pipes. flexible tube 6
consists of a long body without a joint in the middle, and the bent portion of the pipe can also be made without a joint by taking advantage of its flexibility.

7 is a joint protection box, and the pipe insertion hole 4
It is attached to the wall 1 from the indoor side. A joint portion at the end of the flexible tube 6 is formed within the protective box 7.

The structure of the joint part is as follows. That is, on the front surface of this protective box 7, a screw tube 8 for a conduit 9 to the faucet 17 is formed at the front, and the conduit 9 is screwed into this. Further, at the rear, a connecting tube 11 is provided at a position corresponding to the back side of the screw tube 8 and is connected to the connecting tube 11, communicating with the screw tube 8 and into which a connector 10 formed at the end of the flexible tube 6 is screwed. A tool 10 is screwed onto the flexible tube 6 to communicate with the conduit 9.

A connector 10 at the tip of the flexible tube 6 is screwed onto a connecting tube 11 to form a joint portion that is accommodated within the protective case 7. Reference numeral 12 denotes an elastic sheet 12, which is inserted through the flexible tube 6 and is provided to close the pipe insertion hole 4. For this reason, a stepped portion 13 is provided at the rear end of the protective box 7.
is formed and the periphery of the elastic sheet 12 is pressed. The peripheral edge of the rear end of the protective box 7 is fixed to the wall 1 by a fixture 14. 15 is an annular ring inserted into the flexible tube 6 inside the protective box 7. 16 is a drainage hole formed in the bottom surface of the protective box 7. 18 is a protective cover.

[Effect]

The wall 1 constitutes a bathroom unit. A flexible pipe 6 inside the sheath pipe 5 is used for piping for supplying water and hot water to the bathroom unit 1. The sheath tube 5 has a role of protecting the flexible tube 6, and thereby, for example, the flexible tube 6 is not buried directly in concrete, and the flexible tube 6 is safely arranged through the sheath tube 5. be able to. The protection box 7 has a joint at the end of the flexible tube 6 formed therein, and has the function of protecting the joint. The elastic sheet 12 is inserted through the flexible tube 6 and closes the pipe insertion hole 4 so that water does not escape to the back side of the wall 1 when water leaks from the joint.

The annular ring 15 is in close contact with the elastic sheet 12 to prevent water from leaking from the insertion hole of the flexible tube 6 in the elastic sheet 12. The drain hole 16 has the function of draining water to the indoor side of the bathroom unit when water leaks from the joint.

[Effect of idea]

According to this invention, if water leaks from the joint inside the protective case 7, it can be drained indoors through the drainage hole 16 formed on the bottom of the protective case 7, and once it is removed from the back side of the wall 1. Once installed, water will not leak in areas that are difficult to repair, and even if water leaks from the joint part of the protective box 7, it will not escape to the back side of the wall 1, preventing piping from being affected by water leakage. It will not cause corrosion or deterioration.
