[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing unit with drainage piping for a multi-story house.

0002

[Prior Art] For example, in a multi-story housing complex such as an apartment house, the horizontal drain pipes of each unit's kitchen, washroom, bathroom, toilet, etc. are merged into a common vertical drain pipe (hard pipe). There is. In this case, if a relatively large amount of wastewater from one of the residences is temporarily discharged into the common vertical drain pipe, this common drainage piping system will be pressurized, causing water to overflow elsewhere, or conversely to cause a siphon effect. At least vertical drain pipes on the top floor should be provided with ventilation pipes that extend upward from the top to communicate with the atmosphere, as this may create a suction effect and have an adverse effect on other residential pipes belonging to the same piping system. is established,
The top is configured to include a vent valve.

[0003] In order to make the construction cost effective, most of the construction of this type of housing complex employs the housing unit construction method.

However, in conventional housing units of this type, the horizontal drainage pipes of the drainage system were installed at the time of factory production of each housing unit, but the common vertical drainage pipes and ventilation pipes were not included. All of the construction was done on-site, and the horizontal pipes for each unit were connected, which required a large amount of on-site man-hours and construction time.

[0005] Regarding individual piping connection methods for this type of drainage system, conventional methods have been disclosed, for example, in Japanese Patent Application Laid-open No. 2-142993.
Various proposals have been made in Japanese Patent Application Laid-open No. 2-35295, Japanese Patent Application Publication No. 2-20732, and Japanese Patent Application Publication No. 1-316589, but all of them are based on on-site construction, so the above-mentioned The problems were exactly the same.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art as described above, and an object of the present invention is to provide a housing unit that can reduce the on-site man-hours for constructing this type of drainage piping.

[0007]

[Means for Solving the Problems] Therefore, in the present invention, each common vertical drain pipe or ventilation pipe connected to each horizontal pipe of the drainage system is manufactured in a factory in a housing unit for a multi-story house. By configuring it to be installed at the same time,
This aims to achieve the above objective.

[0008]

[Function] With the housing unit structure of the present invention as described above, at a construction site, the vertical drainage pipes of each unit can be connected to each other, and for example, in a unit for the top floor, the ventilation pipe and the vertical drainage pipe of the lower floor can be connected to each other. By interconnecting the pipes, the entire drainage piping system is completed, reducing the number of on-site construction man-hours and construction period.

EXAMPLES The present invention will be explained below based on examples. FIG. 5 shows an explanatory plan view of the part to which the present invention is applied, and FIGS.
) and a vertical cross-sectional view of a main part of an example of each housing unit on the top floor (for example, 3rd floor).

(Configuration) FIG. 5 is a plan view of an example of this type of housing, where 1 is a housing unit including a drainage system of a steel rigid frame structure with pillars 2 at the four corners, 3 is a bathroom, and 4 is a common vertical unit. Indicates piping location. Also, 5 is a living room and 6 is a common hallway.

In FIGS. 1 and 2, 7 is a floor beam, 8 is a lightweight foam concrete floor plate, 9 is a living room floor, 10 is a bathroom floor surface, 1
1 indicates the pillar and 12 indicates the ceiling. Further, 13 is a common vertical drain pipe, and 14 is a reinforcing plate for attaching it. 15 is a horizontal drainage pipe from the washroom and bathroom 3, 16 is a T-shaped three-way joint, 1
7 indicates each pipe joint. Reference numeral 18 in FIG. 2 denotes a ventilation pipe, and a ventilation valve 20 is attached to the top of the pipe via an increaser 19.

(Other Embodiments) FIGS. 3 and 4 show separate common vertical drain pipes 1 from each horizontal pipe 15a, 15b from two drainage systems from the toilet bowl 21 and the kitchen.
5a and 15b, the same (equivalent) components as in each of the above figures are indicated by the same or equivalent symbols with suffixes such as a and b, and there are no duplicates. Explanation will be omitted.

(Function) With this type of housing unit configuration as described above, the drainage pipe system piping at the construction site is connected to the top of each vertical pipe in the housing unit on the lower floor (for example, the 1st floor).
Each vertical drain pipe 13 of the upper floor (for example, 2nd floor) housing unit,
13a, 13b, etc., and the top of each of these vertical drain pipes 13, 13a, 13b, etc. to the top floor (
For example, by connecting the lower part of the ventilation pipes 18, 18a, 18b, etc. on the 3F) using respective joints 17, 17a, 17b, the piping of the entire drainage system is completed, which greatly reduces the on-site man-hours and construction period. can do.

[0014] Although each of the above embodiments has been described in the case where a three-story house has one or two common vertical drainage pipes, it is of course not limited to this, and any arbitrary pipe can be used. Of course, the principles of the present invention can also be applied in the case of hierarchical and multiple vertical drainage pipes.

[0015]

[Effects of the Invention] As explained above, according to the present invention, common vertical drainage pipes or ventilation pipes for the top floor are installed in each multi-story housing unit during factory production. At a construction site, the piping of the entire drainage system is completed by interconnecting the vertical water pipes or ventilation pipes between the upper and lower floor units, which can significantly reduce the number of on-site man-hours and construction period.
