Description

  The present invention relates to a water supply pipe arrangement structure.

Conventionally, when connecting a water supply pipe to a water supply device such as a faucet in a detached house, the water supply pipe is pulled horizontally in the ground around the building and started up at a predetermined position, and provided on the first floor of the building The inside of the building was drawn from the drawn-in hole, and was arranged up to a predetermined connection position. The pull-in position at that time was generally the position closest to the water supply device unless otherwise restricted.
This is the same regardless of whether the water supply pipe is made of a material having no flexibility such as a hard vinyl chloride lined steel pipe or a material having flexibility such as a crosslinked polyethylene pipe.

  When changing the position of the water supply device or replacing it with another device, it is necessary to change the arrangement position of the water supply pipe (the connection position between the water supply apparatus and the water supply pipe). However, it is necessary to add a water supply pipe with the change in position. In addition, the possibility of water leakage increases as the number of additional points increases. Even if the water supply pipe is made of a flexible material, it cannot be used when the distance from the retracted position becomes long.

  The present invention has been made in view of the above circumstances, and has a water supply pipe arrangement structure that can be used without changing the water supply pipe when changing the position of the water supply apparatus or replacing it with another apparatus. It is intended to provide.

  An arrangement structure of a water supply pipe according to the present invention is an arrangement structure of a water supply pipe for connection to a water supply apparatus, wherein the water supply pipe is made of a flexible material and is connected to the water supply apparatus. It is drawn into the inside of the building at a position away from the building, and is arranged in an arc shape or a screw shape inside the wall from the drawing position to the connection position with the water supply device.

In the water pipe arrangement structure configured as described above, the water pipe is made of a flexible material, and is arranged in an arc shape or a screw shape inside the wall from the drawing position into the building to the connection position with the water supply device. Therefore, when the position of the water supply device is changed or replaced with another device, it is possible to cope without adding or replacing the water supply pipe.
In addition, the water hammer can be prevented because the direction of water flow is not changed suddenly.

  According to another aspect of the present invention, the water supply pipe is constituted by a continuous (one-turn) pipe having no joint inside the wall.

  According to said structure, since the water supply pipe is comprised with the pipe | tube of 1 continuous (one roll) without having a joint inside a wall, the danger of the water leakage inside a wall can be reduced.

  The arrangement structure of the water supply pipe according to the present invention can cope with the change of the position of the water supply apparatus or the replacement with another apparatus without adding the water supply pipe.

It is the schematic of the arrangement structure of the water supply pipe | tube which concerns on embodiment of this invention. It is a section schematic diagram of the arrangement structure of the water supply pipe concerning the embodiment of the present invention.
