Description

The present invention relates to a water supply / drainage system for a water supply facility in a detached house or an apartment house.

  Drainage generated in daily life in detached houses and apartment houses is generally built into the foundation of the drainage pipes attached to water facilities such as kitchens, washing machine places, washrooms, and bathrooms and toilets. Piping is sent to a drainage main pipe buried outside the foundation through a piping sleeve (through hole) formed on the foundation, and through the drainage main pipe through the drainage mass installed in the site, under the public road Sent to buried sewers.

  In addition, the water supply to the water supply facility is the same as the drainage, in which the water supply pipe is piped in the foundation of the building or buried outside the foundation, and the hot water supply pipe is basically under the floor or the wall, etc. Embedded in.

  As described above, the conventional building water supply / drainage system does not like that the water supply / drainage system is exposed outside the building from the viewpoint of appearance, and basically the drainage pipe and / or the water supply pipe is provided inside or outside the foundation of the building. There is a need to arrange.

However, in order to arrange the water supply / drainage pipes that make up the water supply / drainage system along the foundation of the building or along the outside of the foundation, in order to draw the water supply / drainage sub-pipe and / or the water supply / drainage pipe to the outside of the building Since it is necessary to form the sleeve, a penetration work for inserting the sleeve is indispensable.
In addition, the surroundings of the water supply / drainage pipe through which the sleeve is inserted require curing work to improve the appearance, and the water supply / drainage pipe placed outside is an extremely cumbersome work such as embedment in the ground. There were many problems such as it was difficult to control.

  As one means for solving these problems, for example, in Japanese Patent Application Laid-Open No. 2001-220791 (Patent Document 1), the sleeve formed on the foundation of the building is only required at one place, and the strength of the building foundation is reduced. In addition, maintenance and management such as inspection and cleaning of drainage pipes can be performed easily, and earthworks costs such as excavation work can be greatly reduced, making it possible to effectively utilize even in small residential land. Has been proposed.

In this residential drainage system, the drainage main pipe is piped along the inside of the outer peripheral foundation of the building under the floor of the building.
At the predetermined position of the drainage main pipe, the outflow side end of the drainage branch pipe connected to various drainage facilities installed in the building is connected, and the downstream end of the drainage main pipe is the outer foundation of the building. It is connected with the inflow side connection part of the drainage burial buried in the outside ground.
Further, a pipe joint for a cleaning port is connected to the upstream end of the drainage main pipe, and a plug body is detachably mounted in the opening end of the pipe joint. It has not been.

On the other hand, drain pipes piped regardless of the inside or outside of a building need to have a certain flow gradient toward the drainage mass laid in the site.
At that time, if the section (distance) that forms the gradient is short, it is not difficult to adjust the gradient, but if the distance is long, a device is required to keep the drain pipe gradient constant. Will be.

  As one of such devices, for example, JP-A-2007-314943 (Patent Document 2) proposes a drainage pipe structure.

As is apparent from FIGS. 2 to 3, the drainage pipe structure has a pair of vertical support portions that are vertically suspended on a rectangular base portion that is horizontally disposed, and is provided above each vertical support plate. A long hole is formed downward and a scale is formed on the side of the long hole, and a horizontal support portion is vertically movable between the long holes and is mounted so as to be fixed at a predetermined position. The drainage pipe is engaged and held by using a locking tool on a long member that is stretched with a certain gradient in the front-rear direction on the lateral support portion. It has not been.

JP 2001-220791 A (Claims) JP 2007-314943 A (paragraphs 0018-0022, FIGS. 2-3, FIG. 7)

Since the housing drainage system described in Patent Document 1 can complete the sleeve formed on the outer peripheral foundation of the building in one place, the strength of the outer peripheral foundation is not impaired, and the effects such as easy construction are obtained. It is supposed to play.
However, since the drainage main pipe is piped under the floor along the outer periphery foundation of the building, it is necessary to remove the floor surface where the drainage main pipe is arranged and enter the inside when performing inspection work or replacement work. Therefore, it cannot be said that the maintenance / inspection work and the replacement work are easy.

In addition, in the drainage pipe structure described in Patent Document 2, the drainage pipe is a pipe that allows drainage to flow from a drainage device on the floor to a junction pipe or the like below the floor, as is clear from FIG. The sleeve 12 is disposed under the floor 12 up to the joining pipe and the like.
Under this floor, the drain pipe is installed so as to have a downward slope from the sleeve toward the joining pipe and the like.
