Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply / hot water supply pipe for a house employing a header method.

[0002]

2. Description of the Related Art Conventionally, a housing adopting a fork branching method in which a branch pipe which has been branched from a main water supply pipe or a main hot water supply pipe sequentially through a joint is connected to a faucet of each water circulating equipment. There are known water supply and hot water supply pipes. However, in such a forked branch method, there are inconveniences such as a large number of connection points, a high occurrence of water leakage due to poor construction, and a large change in flow rate when the water plumbing equipment is used at the same time.

[0003] In recent years, a water supply method using a header method has been adopted, in which a main water supply pipe or a branch pipe branched from a main hot water supply pipe through a header in an octopus-like manner is connected one-to-one to a water faucet of each water circulating facility.・ Hot water supply piping is becoming widespread. In such a header method, compared with the fork branch method, the number of connection points is small and water leakage due to poor construction can be significantly suppressed, and the flow rate change is small when simultaneous use of water circulating equipment, stable water supply, Hot water is available.

[0004]

In the above header method, when a trouble such as water leakage occurs, the branch pipe passing through the concrete floor or the wall can be easily replaced. For protection, an empty pipe called a sheath pipe is preliminarily piped, and then a flexible branch pipe is inserted into the sheath pipe. Also when connecting to a water supply facility through the body, a branch tube is inserted into a sheath tube disposed in the wall by penetrating the floor material. Therefore, the laying of the sheath tube and the work of inserting the sheath tube into the sheath tube are required, which leads to an increase in labor and cost for the construction. Moreover, since the sheath tube has a large outer diameter and is hard to bend, the workability is also deteriorated from this.

[0005] Further, when a sheath tube is laid in a wall body, the puffing of the wall becomes large, which also affects the architectural plan. Further, since there is a gap between the sheath tube and the branch tube, when a water hammer occurs, the branch tube is crushed and collides with the sheath tube, thereby causing a problem that noise is easily generated.

In view of the above, the present invention has been made in view of the above, and has as its object to provide a header type water supply / hot water supply pipe which has good workability, is excellent in economic efficiency, does not affect a building plan, and generates little noise. The purpose is.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention divides a main water supply pipe or a main hot water supply pipe into a plurality of branch pipes via a header, and divides these branch pipes into corresponding water pipes. This is a header type water supply / hot water supply pipe that leads to equipment, and a resin branch pipe is raised into the wall by penetrating the floor material from under the floor, and is installed in the wall through a joint disposed in the wall. , And only the floor material penetrating portion of the branch pipe is covered by the protective pipe.

According to the second and third aspects of the present invention, the branch pipe is made to rise into the partition wall, and is made of crosslinked polyethylene or polybutene.

In the invention of claim 4, the header is arranged under the floor, and the branch pipe is routed under the floor.
