Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a drain pipe used in a building, for example, a middle or high-rise house, and in particular, a one-pipe type drain pipe for flowing sewage and miscellaneous drainage into the same drain pipe. The present invention relates to a drainage device provided.

(Conventional technology) In a building such as an apartment house, a hotel, and an office, drainage from a drainage device provided in a living room is connected at one end to a horizontal drainage pipe and at the other end to a drainage stand. The drainage was carried out by a horizontal drainage branch pipe connected to the pipe. The vertical drainage pipe was placed in the living room, and the horizontal drainage branch pipe was a single pipe.

Therefore, when the drainage pipe is deteriorated, it is necessary to replace it. However, in the conventional apparatus, since the drainage pipe is arranged in the living room, the operator needs to enter the living room at the time of replacement. However, when a person actually lives in the living room, the pipe replacement work becomes troublesome. In addition, the side drainage pipes through which kitchen drainage flows are cleaned to prevent clogging, but they are severely degraded and need to be replaced regularly, and replacement work in living rooms is troublesome. In addition, the cost was high.

In order to solve such a problem, the present applicant has already made it possible to replace only the inner pipe by making the lateral drainage branch pipe a double pipe structure, and to install the drainage pipe outside the room to easily perform the replacement work. We propose a drainage device that can be used.

(Problems to be Solved by the Invention) In the above drainage device, the inside of the lateral drainage branch pipe can also be cleaned from the outdoor side by, for example, a high-pressure water cleaning method. In this case, if the washing machine is excessively inserted into the lateral drainage branch pipe from its outdoor end, and the tip of the washing machine breaks through a water sealing portion such as a trap of the drainage device, the washing water is spouted from the drainage device into the room. Therefore, in order to prevent such a jetting accident from occurring, it is necessary to insert the washer from the outside of the room while paying close attention, for example, while keeping in contact with workers in the room, and it is efficient. This causes a problem that the cleaning operation cannot be performed.

The present invention has been made to solve the above problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention has taken the following technical means.

That is, the drainage device for a building according to the present invention is a drainage device in which a drainage device 4a provided in a room of a building and a drainage riser 6 erected outside the room are connected by a horizontal drainage branch pipe 5a. A cleaning port 21 and an opening / closing lid 22 are provided at a connection portion between the horizontal drainage branch pipe 5a and the drainage vertical pipe 6, and the length of the horizontal drainage branch pipe 5a from the connection portion to the vicinity of the drainage device 4a is reduced. , This horizontal drainage branch pipe
5a, which is displayed on the drainage riser 6 or the outdoor area of the connection portion, or on a wall surface of a building near the connection portion.

(Operation) According to the present invention, since the length of the lateral drainage branch pipe 5a is displayed in the outdoor area near the connection between the horizontal drainage branch pipe 5a and the drainage vertical pipe 6, for example, When performing the cleaning work of the pipe 5a, the work is performed by determining the length of insertion of the washing machine from the cleaning port 21 based on the above indicated value, and thereby the indoor drainage device 4a is cleaned.
Therefore, the cleaning operation can be performed without piercing the water sealing portion of the cleaning water, and without causing an accident of flushing the cleaning water into the room.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a drainage pipe of a living room 1 of a high-rise apartment house. The living room 1 is separated from an outdoor area 3 by a wall 2. Inside the living room 1, drainage devices such as a kitchen sink 4a, a toilet 4b, a basin 4c, a bathtub 4d, and a laundry 4e are provided. Drainage from these drainage devices is supplied to horizontal drainage branch pipes 5a and 5b.

It is composed of connected single tubes. The branch pipes 5a and 5b are substantially parallel to each other on the outdoor section 3 side and penetrate the wall 2 orthogonally.

The lateral drainage branch pipe 5a having the double pipe structure has one end connected to the kitchen sink 4a and the other end connected to the drainage riser 6 by an elbow joint pipe 7a.
And via a collecting pipe 8 so as not to be directly orthogonal to the collecting pipe 8. The outer pipe 9 of the branch pipe 5a is a rigid pipe,
The flexible inner tube 10 is a flexible tube made of a heat-resistant synthetic resin (for example, a polyethylene pipe, a polybutene pipe, or the like).

The collecting end of the lateral drainage branch pipe 5b is connected to the branch pipe joint 11 of the collecting pipe 8 at right angles to the collecting pipe 8.

The drainage pipe 6 is disposed in the outdoor area 3 and is connected to the upper and lower joints 13 and 14 of the collecting pipe 8 fixed to each floor slab 12 of the building as shown in FIGS. 2 and 3. ing.

The elbow joint pipe 7 has a branch pipe joint 15 provided in the orthogonal direction to the branch pipe joint 15 provided in the collecting pipe 8 in a direction orthogonal to the pipe axis, and one end of the branch pipe joint 15 as viewed in a plane. It is detachably attached by a bolt 16 so that it is shaped and the other end opening faces in the same direction as the opening of the branch pipe joint portion 11. The other end opening of the joint pipe 7 is formed as a branch pipe joint 17, and the branch pipe joint 17 is provided with a cap nut 18 and a ring seal 19 as shown in FIG. An adjusting outer pipe 20 screwed to one end of the outer pipe 9 of the horizontal drainage branch pipe 5a is connected.

Further, a cleaning port 21 is provided on the upper surface of the elbow joint pipe 7, and an opening / closing lid 22 is detachably fixed by bolts 23.

After the outer tube 9 is fixed to the pipe, the flexible inner tube 10 is inserted from the cleaning port 21 while measuring its length, and the distal end of the flexible inner tube 10 is connected to the outer tube 9 as shown in FIG. And connected to the elbow pipe 24 directly below the water sealing trap (not shown) of the kitchen sink 4a.
