Abstract

PURPOSE:To freely arrange drain facilities without requiring accurate setting-out and construction by making plural drain pipes for respective apparatuses radial piping with a collecting part as a center, and communicating the collecting part and a drain vertical pipe with a collecting pipe. CONSTITUTION:A collecting pipe 3, connected to a drain vertical pipe 2 at one end and extending obliquely upward from a connected part, is provided, and a collecting part 4 is arranged in the other end of the collecting pipe 3. The collecting part 4 is composed of an octagon housing 5, and plural drain pipes 12 for respective apparatuses are joined to the joint part of the housing 5. Moreover drain facilities are connected to the other ends of the drain pipes 12. This can reduce spaces in a vertical direction for piping.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to drainage piping in housing complexes.

0002

2. Description of the Related Art Conventionally, as shown in FIG. 5, drainage piping in an apartment complex has been constructed such that, for example, a main drainage pipe 22 that connects a drainage standpipe 20 and a kitchen 21 is connected to a unit bath 23, a washbasin, and a sink. It was a so-called branch pipe system in which drain pipes 25, 26, etc. from 24, etc. were connected.

0003

[Problem to be Solved by the Invention] However, in such branch pipe type piping, various types of drainage gradually join the drainage of the main drainage pipe 22, so it is difficult to carry out the construction. Therefore, it is necessary to accurately mark out and install the location of each appliance and the location where the drain pipe will be routed. Furthermore, it is almost impossible to change the location or layout of water sources, toilets, bathrooms, kitchens, washrooms, etc. after construction is completed. Even if it were done, it would be difficult because it would require changing all the drainage pipes in the dwelling unit from the drainage standpipe.

0004

[Means for Solving the Problems] The present invention relates to drainage piping in an apartment complex, including a drainage standpipe, one end of which is communicated with the drainage standpipe, a collecting pipe extending from there, and a collecting pipe provided at the other end of the collecting pipe. The device is characterized by comprising a collecting section with a plurality of drains, and a plurality of drain pipes extending from the collecting section to each device.

[0005]

[Function] In the drainage piping according to the present invention, the piping is arranged in a radial pattern with the collecting part as the center, so the drain pipe can be arranged in any direction from the collecting part.
You will be able to freely arrange the unit bath, washstand, sink, and other drainage equipment.

[0006] Furthermore, there is no need for accurate marking or construction, and the construction can be easily performed and the construction can be streamlined.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Drainage piping in a housing complex according to a preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram showing a drainage pipe 1 in an apartment complex according to an embodiment of the present invention. Drainage pipe 1 is
Like conventional drainage piping, it has a drainage standpipe 2 for collectively discharging the drainage water from the residential units arranged above and below. The drain standpipe 2 has a collecting pipe 3 that is connected to the drain standpipe 2 at one end and extends obliquely upward from there. A collecting portion 4 is provided at the other end of the collecting pipe 3. This gathering part 4
As shown in FIG. 2 and subsequent figures, it has an octagonal housing 5, and inside the housing 5, there is an outlet pipe joint part provided so as to extend inward from one side of the housing 5. 6. As an extension of this outlet pipe joint part 6, a first inlet joint part 7 is provided which extends to the opposite side of one side of the housing 5. These outlet pipe joint part 6 and first inlet joint part 7 are arranged in a straight line, and are inclined slightly diagonally downward from the first inlet joint part 7 toward the outlet pipe joint part 6 with respect to the housing 5. It is arranged as follows.

The housing 5 further includes a second inlet joint part 8 and a third inlet joint part 9 extending orthogonally to the first inlet joint part 7, and the first inlet joint part 7 and the second inlet joint part. 8
A fourth inlet joint part 10 and a fifth inlet joint part 1 are arranged between the first inlet joint part 7 and the third inlet joint part 9, respectively.
1 is provided. The second inlet joint part 8, the third inlet joint part 9, the fourth inlet joint part 10, and the fifth inlet joint part 11 connect the first inlet joint part 7 and the outlet joint part 6 from one side of the housing 5. towards the first inlet joint part 7. In addition, the second inlet joint part 8, the third
Inlet joint part 9, fourth inlet joint part 10, fifth inlet joint part 1
1 is configured such that the angle at the point of convergence with the outlet pipe joint part 6 is small so that the waste water flowing therein flows smoothly into the outlet pipe joint part 6.

The collecting pipe 3 is connected to the outlet joint 6, and the inlet joints 7, 8, 9, 10,
11 is connected to a drain pipe 12 for each device. Each of these equipment drain pipes 12 extends diagonally upward in a radial manner, and at the other end of each equipment drainage pipe 8, although not shown,
The kitchen sink, washstand, unit bath, etc. are each connected.

[0011] The drain pipes 12 for each device are connected to the collecting part 4.
By making it possible to connect the devices in various patterns, it is possible to easily adapt even if the planar layout plan of each device is different.

0012

[Effects of the Invention] As explained above, in the drainage piping for an apartment complex according to the present invention, the drainage pipes for each device are arranged in a radial manner with the gathering part as the center, so that the slope of the drainage piping is Since only two stages of inclination are required for the drain pipe and collecting pipe of each device, the vertical height for piping can be reduced. Therefore, the required space in the vertical direction can be reduced, and as a result, each dwelling unit can be made spacious with a high ceiling.
