Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 to FIG. 4 show an embodiment of the present invention.

First, the structure will be described. Reference numeral 1 in FIG.
The first floor unit of the unit house, reference numeral 2, is a second floor unit, and each of these units 1 and 2 is provided with a first floor piping unit 3 and a second floor piping unit 4, respectively.

In each of the piping units 3 and 4, drain pipes 7 and 8 and water supply pipes 9 and 10 as unit pipes are respectively fixed along frames 5 and 6 in which rectangular pipes are assembled. I have.

The drain pipes 7 and 8 are connected by a drain pipe joint member 11 as a joint member, and the water supply pipes 9 and 10 are connected by a water pipe joint member 12 as a joint member.

As shown in FIG. 3, the drain pipe joint member 11 has an upper mounting pipe 13 and a lower mounting pipe 14 made of, for example, a PVC-lined steel pipe.
3 and 14 are connected by a rubber bellows member 15 as a flexible portion. At the upper end 15a of the bellows member 15,
The lower end 13a of the upper mounting pipe 13 is inserted and mounted inside, and the lower end 15b of the bellows member 15 is inserted and mounted inside the upper end 14a of the lower mounting pipe 14. Moreover, the upper end portion 13b of the upper mounting pipe 13 has an enlarged diameter.
The lower end 8 of the drain pipe 8 is provided in the receiving port.
a is inserted and attached. The lower end portion 14b of the lower mounting pipe 14 is formed as a spout.
The difference port is adapted to be mounted is inserted into the upper portion 7a of the drain pipe 7.

In the water supply pipe joint member 12, as shown mainly in FIG. 4, an upper mounting pipe 16 and a lower mounting pipe 17 are connected by a stainless flexible pipe 18 as a flexible portion. The stainless flexible pipe 18 is screwed to both straight pipes 16 and 17 via a socket 19. The upper mounting pipe 16 is connected to the lower end 10a of the water supply pipe 10.
Further, the lower mounting pipe 17 is connected to each of the upper end portions 9 a of the water supply pipe 9.

Next, the operation will be described.

In the factory, the first-floor piping unit 3 and the second-floor piping unit 4 are provided in the first-floor unit 1 and the second-floor unit 2 in advance, respectively. In this state, they are transported to the site, the first floor unit 1 is installed, and then the second floor unit 2 is placed thereon.

Thereafter, the drain pipes 7, 8 are connected via a drain pipe joint member 11, and the water supply pipes 9, 10 are connected via a water pipe joint member 12, respectively.

The drain pipe joint member 11 is attached to the upper end 13 b of the upper mounting pipe 13 by inserting the lower end 8 a of the drain pipe 8 and mounting the lower end 1 of the lower mounting pipe 14.
4b is inserted into the upper end 7a of the drain pipe 7 and attached.

The water supply pipe joint member 12 includes an upper mounting pipe 16 for the water supply pipe 10 and a lower mounting pipe 17 for the water supply pipe 9.
To each.

In such a case, since the pipes 7, 8, 9, and 10 are attached to the piping units 3 and 4 in advance, the first floor unit 1 and the second floor unit 2 are installed on site. In the state in which the water supply pipes 9 and 10 and the water supply pipes 9 and 10 are assembled, the distance between the drain pipes 7 and 8 may vary, or the axis may be shifted. However, even in such a case, by connecting the drain pipes 7 and 8 and the water supply pipes 9 and 10 via the joint members 11 and 12, the bellows member 15 of the joint members 11 and 12 and the flexible flexible pipe 18 of the stainless flexible pipe 18 can be formed. Due to the nature, the above positional deviation can be absorbed.

Therefore, since each of these pipes 7 is mounted at a predetermined position in advance, the pipe units 3 and 4 can be connected to each other without an operator setting the pipes at a predetermined position on site. If it is attached to a house, each pipe 7 automatically
Is set at a predetermined position, and can be easily connected to each pipe 7... Via each joint member 11, 12. Unlike the case where individual pipes are provided, the number of work steps is reduced. At the same time, the quality of the equipment piping does not vary from worker to worker, and the quality is ensured.

Also, since the upper member is always inserted and attached to the lower member at the connection between the drain pipes 7 and 8, leakage of drain water flowing downward from above is easily prevented. can do.

Further, a large internal pressure acts on the water supply pipes 9 and 10, but by using the stainless flexible pipe 18 or the like, it is possible to easily withstand the internal pressure.

Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to this embodiment, and there may be design changes within the scope of the present invention. Even this is included in the present invention. For example, in the above-described embodiment, the present invention is applied to the connection of the pipes 7 between the first-floor piping unit 3 and the second-floor piping unit 4, but the invention is not limited to this. Of course, it goes without saying that the present invention can also be applied to the connection between the piping of one piping unit and the piping of another part.

[0027]

As described above, according to the present invention, since a plurality of unit pipes including a predetermined drain pipe and a water supply pipe are previously attached to a frame, the individual pipes can be individually installed on site as in the prior art. Unlike the case where pipes are connected to each other, the number of work steps is reduced, and the quality of the equipment pipes is hardly different between operators, so that the quality can be ensured. In addition, the flexible portion of the joint member absorbs the positional deviation between the pipes, and has a practically useful effect that both pipes can be reliably connected. Also, configure the unit piping.
