[0004]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the piping configuration of a room in an apartment house such as an apartment building. A plurality of floor boards 1, 1, formed in a square shape of a predetermined module, for example, are placed on a floor slab of the room.
1 are laid to form a double bottom, and each floorboard 1 is provided with legs 1a extending in four directions, and a space for piping is formed between the floor slab and each floorboard 1. I have.

[0005] A relay box 3 having the same module as each floor panel 1 and formed in a square shape is installed at an interval in the center of the room, and each relay box 3 is formed in the same module as the floor panel 1. Therefore, it can be installed in a buried state between the floor boards 1, and a lid 3 b is provided on the upper surface of each relay box 3 so as to be openable and closable, and the lid 3 b is fitted so as to be flush with the floor board 1. Things.

The relay box 3 is formed in a box shape whose upper surface is open, and a plurality of through holes 3a, 3
a, 3a are formed, and as shown in the enlarged plan view of FIG. 2, the sheath tubes 4, 4, 4 are fitted in advance in the respective through holes 3a, 3a. , 4,4
It is configured so that a drain pipe and a water supply pipe can be passed through each. As shown in FIG. 2, drain pipes 5a, 5b and 5c, 5d are passed through the outer sheath pipes 4, 4, 4 and a water supply pipe is located inside the central sheath pipes 4, 4. 6 and a hot water supply pipe 7 are disposed therethrough.
a, 5b, 5c, 5d, the water supply pipe 6, and the hot water supply pipe 7 constitute a main pipe A passing through the center of the room.

In the relay box 3, a branch pipe B is connected to the main pipe A, and a plurality of drain pipes 5a, 5b, 5c, 5d are respectively perpendicularly inserted through elbows or the like. The branch pipe B is connected to the water supply pipe 6 and the hot water supply pipe 7, and the branch pipe B is branched at right angles through a branch connection pipe. The ends of the main pipe A are respectively connected to standing pipes 9, 9 vertically provided in a pipe space, and the drain pipes 5a, 5b,
5c and 5d are respectively connected to a vertical pipe 9 for drainage, the water supply pipe 6 is connected to a vertical pipe 9 for water supply, and a hot water supply pipe 7 is provided.
Is connected to the water heater 11. Note that in the figure, 10
Is a storage tank for drainage.

On the other hand, the branch pipes B are respectively drawn sideways to terminal boxes 8 arranged on the outer peripheral side of the room, and a rise pipe or a hose or the like is further connected to the branch pipes B in each terminal box 8. The toilet unit 12 and the kitchen unit 13 can be connected and installed with a short pipe from the terminal box 8, and the toilet unit 12 is provided with a pumping pump 12a for pumping drainage. The kitchen unit 13 also pumps drainage. Pump 13 to perform
a, and the drainage is pumped from the pressure pumps 12a, 13a through the branch pipe B of the terminal box 8 to any of the drain pipes 5a, 5b, 5c, 5d of the main pipe A, and a standing pipe in the pipe space is provided. 9, and the individual drain pipes 5 a, 5 b, 5
c, 5d are connected so as to be able to drain well.

When connecting the piping from the terminal box 8 to the equipment 14 along the wall surface, a rising box 15 or a horizontal box 16 is used to hide the exposed piping.
It is possible to form a neat room by concealing the pipe by using the method described above. Note that, in FIG.
Is a drain outlet, and 18 is a faucet box.

As described above, if the room has a double floor and the relay boxes 3 and 3 and the terminal boxes 8 and 8 are installed, the units 12 and 13 and other equipment 14 and the like can be relocated or expanded. In this case, the terminal box 8 can be connected to these devices with a short pipe, and can be moved, etc., and there is no need to peel off the floor as in the conventional case. What you can do.

The renewal of the main pipe A and the branch pipe B can be easily performed without breaking the floor via the relay box 3 and the terminal box 8, and the sheath pipe 4 is provided. Subsequent piping work can be easily performed through the pipe in the pipe 4 well. Further, since a plurality of pipes can be arranged under the floor in an orderly manner via the relay box 3 and the terminal box 8, the pipes do not cross under the floor in a complicated manner, and maintenance and the like are easy. Also, the relay box 3 and the terminal box 8
Is set in the same module as the modular floorboard 1 that forms the double floor, positioning and the like become unnecessary at the time of construction, and a neat arrangement state can be obtained.

In this embodiment, the drain box, the water supply pipe and the like are provided in the relay box 3 and the terminal box 8, but the relay box 3 and the terminal box 8 are not shown.
As shown in FIG. 3, the outlets 3c, 3c, 3c
Is formed, for example, the ventilation pipe 2 is inserted in the relay box 3.
0, and the hot air or the like is blown through the ventilation pipe 20 and the outlet 3c.
The inside of the relay box 3 may be formed with a connection port 3d, and the exhaust pipe 21 may be formed in the relay box 3 as shown in FIG. Through the connection port 3d so that the suction device 22 and the like can be connected with one touch, the exhaust pipe 21
And a central cleaner can be formed in the room by suction.

[0013]

According to the piping structure of the present invention, a trunk pipe is arranged from a vertical pipe vertically installed in a pipe space to a relay box buried with a removable lid under the floor at the center of the room under the floor. A branch pipe is arranged from the relay box to a buried terminal box provided with a detachable lid below the floor on the peripheral side of the room, and the pipe is connected from the terminal box to a plumbing device installed indoors. With this configuration, relocation and expansion of plumbing equipment at the time of renovation etc. can be performed in the entire room, there is no need to peel the floor when relocating or expanding, and relocation of plumbing equipment at a short time and at low cost , Which has the effect of enabling extension.

Further, since a sheath pipe for passing a pipe is disposed between the relay box and the terminal box, etc., the pipe is satisfactorily passed through the sheath pipe to facilitate the renewal of the pipe and maintenance. It has the effect that can be performed.
