Description

[Detailed explanation of the idea] The present invention relates to a collecting pipe for drainage.

In conventional drainage piping, the collecting pipe used to connect the drainage standpipe and side branch pipe is integrally formed as a whole, including multiple branch pipe connections, and the vertical branch pipe connections are It was not possible to adjust the separation distance or the relative angle in the circumferential direction of each branch pipe connecting portion, making it extremely difficult to connect the side branch pipes.

The present invention solves the above-mentioned conventional drawbacks, and aims to provide a collecting pipe in which the relative position of the horizontal pipe connection part can be easily adjusted according to the position of the horizontal branch pipe during piping.

In order to achieve the above purpose, the collecting pipe of the present invention has the following features:
It has a standpipe connection part to which a drainage standpipe is connected at one end, and the other end side of the standpipe connection part is formed with an upper large diameter part having a larger diameter than the drainage standpipe, and the upper diameter part of this upper large diameter part is larger than the drainage standpipe. An upper collecting pipe having an upper branch pipe connection part on the side and the other end of the large diameter portion of the upper part formed into a spigot, and one end thereof is connected by fitting externally to the spigot of the upper collecting pipe. a lower collecting pipe having a socket, the other end side of which is formed as a lower large diameter part, and a lower branch pipe connection part on the side of the lower large diameter part, and an insert of the upper collecting pipe. This configuration includes a coupling device that detachably couples the opening and the socket of the lower collecting pipe.

According to this configuration, by cutting the other end of the upper collecting pipe, the separation distance between the upper branch pipe connecting part of the upper collecting pipe and the lower branch pipe connecting part of the lower collecting pipe can be arbitrarily adjusted, and By relatively rotating the collecting pipe and the lower collecting pipe around the pipe axis, the relative angle in the circumferential direction between the upper branch pipe connection part of the upper collecting pipe and the lower branch pipe connection part of the lower collecting pipe can be arbitrarily set. Can be adjusted.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 1, 1 is a collecting pipe consisting of an upper collecting pipe 2 and a lower collecting pipe 3, and the upper collecting pipe 2
has a standpipe connection part 4 at one end to which a drainage standpipe (not shown) is connected, and the other end of the standpipe connection part 4 has a diameter that gradually increases from one end to the other end. The upper part has a larger diameter than the drainage standpipe through the tapered part 5 which becomes larger. Also, this upper collecting pipe 2
has an upper branch pipe connection part 6 to which a horizontal branch pipe (not shown) is connected on the circumferential side of the large diameter part of the upper part, and the other end of the large diameter part of the upper part is formed into a spigot. . The lower collecting pipe 3 has one end formed as a socket that fits onto the spigot of the upper collecting pipe 2 with a slight gap in the radial direction, and has a flange part 7 on the outer peripheral surface of the one end. However, slightly on the other end side of the flange portion 7, there are three lower branch pipe connecting portions 8a to 8c to which horizontal branch pipes (not shown) are connected. The lower collecting pipe 3 also has a standpipe connection part 9 at the other end to which a drainage standpipe (not shown) is connected, and one end of the standpipe connection part 9 is connected to the other end. A lower portion with a larger diameter than the drainage standpipe is formed through a tapered portion 10 whose diameter gradually increases toward the side. At the other end of the upper collecting pipe 2, there is an annular elastic body 1 whose axial portion is fitted into the flange portion 7 of the lower collecting pipe 3.
1 and an annular push ring 12 that comes into contact with the end surface of the elastic body 11 on one end side of the upper collecting pipe 2, and the push ring 12 and the flange portion 7 are connected to each other by a plurality of bolts 13 and nuts 14. The elastic body 11, push ring 12, bolt 13, and nut 14 constitute a coupling device.

As shown in FIGS. 2 and 3, the lower manifold pipe 3 is provided on the inner wall of the other end side of the lower branch pipe connection parts 8a to 8c over 5/4 of the circumference in the circumferential direction, and A crescent-shaped blade body 15 is provided spirally from one end side to the other end side, and the waste water flowing down from above is forcibly swirled by this blade body 15 to the lower collecting pipe. It will flow down while swirling along the inner wall of No. 3.

The lower collecting pipe 3, including the blade body 15, is integrally cast, and the upper collecting pipe 2 is also entirely cast as one piece. Note that 16 is the bolt 2
This is a bolt hole through which 0 is inserted.

In this way, the collecting pipe 1 is divided into the upper collecting pipe 2 and the lower collecting pipe 3, and the upper branch pipe connecting part 6 and the lower branch pipe connecting parts 8a to 8c are respectively provided. The relative directionality with the lower branch pipe connecting parts 8a to 8c can be set arbitrarily, and since the connecting part between the upper collecting pipe 2 and the lower collecting pipe 3 is located above the floor surface, it is possible to set the relative direction to the lower branch pipe connecting parts 8a to 8c. The through hole to be installed can be made smaller, and the upper collecting pipe 2 and lower collecting pipe 3 can be separately transported to the site and assembled on site. Moreover, since the upper collecting pipe 2 and the lower collecting pipe 3 are connected by the elastic body 11 and the press ring 12, by cutting the appropriate length of the spigot of the upper collecting pipe 2, the upper branch pipe connecting part 6 and the lower collecting pipe are connected. Branch pipe connection parts 8a-8
The separation distance from c can be set arbitrarily. Therefore, during piping, the upper branch pipe connecting portion 6 and the lower branch pipe connecting portions 8a to 8c can be easily connected to each side branch pipe, and the piping work can be performed quickly.

In the above embodiment, the collecting pipe 1 is divided into an upper collecting pipe 2 and a lower collecting pipe 3, an upper branch pipe connecting part 6 and a lower branch pipe connecting part 8a to 8c are provided respectively, and an elastic body 11 and a push ring are provided. 12, the upper branch pipe connection part 6 and the lower branch pipe connection parts 8a to 8c do not necessarily need to be provided in this way, and their positions and numbers may vary depending on various design conditions. It may be determined as appropriate. Further, any other configuration may be used as the coupling device for connecting the upper collecting pipe 2 and the lower collecting pipe 3.

As explained above, according to the present invention, the collecting pipe is separated into an upper collecting pipe and a lower collecting pipe, and the socket of the lower collecting pipe is fitted onto the spigot of the upper collecting pipe, and these are connected by a coupling device. By cutting the spigot of the upper collecting pipe to an appropriate length, the distance between the upper branch connecting part of the upper collecting pipe and the lower branch connecting part of the lower collecting pipe can be adjusted as desired. ,
In addition, by rotating the upper collecting pipe and the lower collecting pipe relatively around the pipe axis, the relative angle in the circumferential direction between the upper branch pipe connecting part of the upper collecting pipe and the lower branch pipe connecting part of the lower collecting pipe can be adjusted. Can be adjusted arbitrarily. Therefore, the horizontal branch pipe and the upper and lower branch pipe connecting portions can be easily connected during piping, and piping work can be performed quickly.
