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 mainly used for houses, and more particularly to a pipe suitable for prefabricated houses.

[0002]

2. Description of the Related Art In a prefabricated house, each unit of the house, for example, kitchen, washroom, bath, toilet is one unit, and dining is one unit. Assembled into a house. When making these units in the factory, we assemble the floors, walls, ceilings, etc. used for the units. This assembly is performed on a belt conveyor or a trolley.

Since the arrangement of the devices in the water around unit of such a prefabricated house is almost the same, the shape and size of the pipes are almost the same. However, since this piping is done at the time of assembling the unit, it is required to be completed in an extremely short time.

Also, in the case of an apartment house, since each house has a standardized internal structure, the plumbing around water is also in a unified form. However, the piping work is concentrated at one time, and it is necessary to carry out the work in a short time until the subsequent process.

In order to shorten the piping construction time, the header construction method has come to be adopted. The header receives water and hot water for each house, and one of the multiple water outlets attached to the header
Connect flexible tubing from one piece to each device. Although the header construction method has shortened the piping construction time, it is required to further shorten the piping construction time.

[0006]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an assembly of a piping member and a piping method thereof, which can significantly reduce the piping construction time and can perform the plumbing work for one unit in several tens of minutes. Is.

[0007]

An assembly of piping members according to the present invention is a water distribution / hot water distribution pipe made of a flexible material having a predetermined length at a water distribution / hot water distribution port of a water distribution / hot water distribution header. Is attached, and a joint is attached to the other end of the pipe if necessary.

According to the piping method of the present invention, a water distribution / hot water distribution pipe made of a flexible material having a predetermined length is attached to each of the water distribution / hot water distribution ports of the water distribution / hot water distribution header, and the other end of the pipe is connected. If necessary, a joint is attached to form an assembly, and the assembly is used to mount the header and pipe at the construction site.

This water distribution / hot water distribution header usually has one water supply / hot water supply port for the header and a plurality of water distribution / hot water distribution ports from the header. The water distribution header has five water distribution ports.
For hot water distribution, there are often four hot water distribution ports. A header bracket for attaching the header to a wall or floor of a building is attached to the header, and a pipe of a predetermined length is attached to the water distribution port via a male adapter if necessary. In addition, a blind plug is screwed into the unnecessary water outlet to stop the water. In the case of a hot water distribution header, a header cover can be attached to keep warm or prevent burns. An elbow is attached to the water supply / hot water supply port of the header as necessary to facilitate connection with the water supply / hot water supply pipe. A sealing cap is attached to the water / hot water supply port to prevent foreign matter from entering during transportation and construction.

The water distribution / hot water distribution pipes used in the assembly of the piping member of the present invention include polybutene pipes, polyethylene pipes which can be connected mechanically or by electric fusion, and stainless steel corrugated pipes. Tubes (SSCT), copper tubes, metal reinforced polyethylene pipes with inner and outer surfaces coated with medium density polyethylene or cross-linked polyethylene, or stainless steel coiled thinner than general-purpose stainless steel pipes specified in JIS G3448.・ A tube (SCT) can be used. When it is necessary to maintain the self-supporting property and bending among these pipes, a copper pipe, a metal reinforced polyethylene pipe, SCT, or the like is used.

In order to prevent scratches during construction, these pipes are often contained in a sheath pipe made of polyvinyl chloride or the like. When installing the water distribution pipe and hot water distribution pipe in the sheath pipe, cover the pipe between the header and the equipment connection joint with the sheath pipe, and then attach the equipment connection joint to the pipe. This instrument connection fitting may be installed at the plumbing site.

The end of the water distribution / hot water distribution pipe opposite to the header is a kitchen sink water supply / hot water tap, a bath water supply / hot water tap,
A water tap / hot water tap for a vanity, a faucet adapter for connecting to a faucet in a toilet or a washing machine, or a faucet elbow is attached, and a start-up corner pipe is a sheath at the place corresponding to the rising part of the pipe. It is attached to the end of the tube. A sealing cap is attached to the openings of the faucet adapter and faucet elbow to prevent foreign matter from entering during transportation and construction.

The piping member assembly of the present invention can be packaged in one box by winding the piping portion of the assembly for one house. However, if you can't pack the auxiliary accessories used for piping, such as self-supporting metal fittings, female adapter for floor attachment, and conduit support (supporting tool used to start the sheath tube as it is) in the same box, they will be packaged separately.

The assembly of the present invention is assembled before piping. Attach a pipe of the required length to the water distribution / hot water outlet of the header for water distribution / hot water distribution, cover the pipe with a sheath pipe if necessary, and attach a start-up corner pipe to the end of the sheath pipe where necessary. . Depending on how it is used, the end of the pipe is fitted with a fitting such as a faucet adapter or a faucet elbow. A blind plug is screwed into the unnecessary water outlet. Attach a sealing cap to the header's water / hot water inlet, or the opening of the elbow and fittings attached to it. In this assembly, the tubes are wound together. At the time of this winding, it is desirable to combine one set of water supply assembly and one set of hot water supply assembly for one house.

[0015]

[Operation] Since this one-unit assembly is shipped in one box, when assembling a unit of a prefabricated house, one box of this assembly can supply water and hot water for one unit. You can save time. Also, it is convenient because all necessary parts are collected. This has also made it easier to pipe to prefabricated housing units on conveyors or trolleys.

FIG. 1 is a perspective view showing an example of piping using the assembly 1 of the piping member of the present invention. This is a product in which the assembly 1 of the piping members is piped to the water surrounding unit floor 2 of the prefabricated house.

An assembly 1 of piping members has a water distribution header 11, a pipe 12 (for example, a polybutene pipe) connected to the water distribution port, and a faucet adapter 13 or a faucet elbow attached to the end of the pipe. ing. A sheath pipe is fitted around the outer periphery of the pipe for pipe protection, and a rising corner pipe 15 is attached to the end of the sheath pipe at the rising portion.
A sealing cap is attached to the water inlet of the header, the faucet adapter, and the opening of the faucet elbow when the pipe member is assembled. Since the hot water distribution header 16 may have a smaller number of water distribution ports than the water distribution header, it is short as shown in the figure. A polybutene pipe 17 is connected to each of the hot water outlets, and a joint is attached to the end of the pipe in the same manner as for water. Sheath pipe, start-up corner pipe, and sealing cap are also installed as for water. The water distribution header and the hot water distribution header are provided with a common header bracket 3 so as to be attached to the floor.

After assembling such an assembly of piping members in a factory, as shown in FIG. 2, the pipe is wound with the header bracket 3, the hot water distribution header 16 and the water distribution header 11 outside. Put the wound assembly into a cardboard box as shown in Fig. 3 and send it to the place where piping work will be performed. As the place where the plumbing work is done, there are a construction site where standardized houses are gathered, such as an apartment house, and a factory where water supply units for prefabricated houses are made. Figure 1 shows the floor part of the water supply unit of a prefabricated house. Take out the assembly of the piping members contained in the cardboard box, attach the header bracket 3 to the floor part, and then install water piping and hot water piping. Will be extended. At the place where the kitchen sink is attached, attach the start-up corner pipe 15 and tap 1
Holds 3. Similarly, hold each faucet by extending the tubing to the point where the vanity, bath, and toilet will be attached. The stretched tube is secured to a suitable location on the floor with a fixture, such as a saddle band. If the length of the pipe is a little longer, you can slacken it on the floor.

A floor plate is pasted on the floor portion thus piped to complete the floor. A wall is attached to this to assemble the water unit. This piping process can be completed in tens of minutes.

[0020]

By using the assembly of the piping member of the present invention for piping, the piping time can be extremely shortened. In addition, since it is a set with only the necessary parts, it is easy to install the parts without the need to lose or collect them.
