（産業上の利用分野）
本発明は、その上下端に排水立管が接続される
継手管に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a joint pipe to which drainage standpipes are connected to the upper and lower ends thereof.
（従来の技術）

を横方向に排水する横枝管と、これら立管と横枝
管との継手管により構成されるものが一般的であ
る。(Prior art) Drainage pipes used in high-rise buildings, etc. are composed of standpipes that drain wastewater vertically, horizontal branch pipes that drain water from drainage equipment on each floor horizontally, and these standpipes and side branches. Generally, it consists of a joint pipe with a pipe.
そして、排水管の設置スペースの軽減のため、
通気管を別途設けることなく、立管自体に通気管
を兼用させる一管式配管のものがある。 In order to reduce the installation space of drain pipes,
There is a one-pipe piping system in which the standpipe itself also serves as a ventilation pipe, without requiring a separate ventilation pipe.
（発明が解決しようとする課題）
従来の一管式配管のものでは、排水自体が立管
を閉塞して流下することにより、管内圧力が上昇
し、排水器具の封水トラツプが破れるといつた問
題があつた。(Problem to be solved by the invention) In conventional one-pipe piping, the drainage itself blocks the standpipe and flows down, increasing the pressure inside the pipe and breaking the water seal trap of the drainage equipment. There was a problem.
また、立管から流下する排水が横枝管内に入り
込んで逆流し、封水トラツプを汚染して悪臭が発
生するという問題があつた。 Additionally, there was a problem in that wastewater flowing down from the standpipe entered the side branch pipe and backflowed, contaminating the water sealing trap and producing a bad odor.
本発明は上記課題を解決することを目的とす
る。 The present invention aims to solve the above problems.

の接続部が設けられている点にある。(Means for Solving the Problems) A feature of the present invention is that inside the joint pipe 1 to which drainage standpipes are connected to the upper and lower ends thereof, a pipe is provided that extends from three sides of the pipe inner wall toward the center of the pipe. A horseshoe-shaped inclined plate 11 that slopes downward toward the remaining inner wall of the pipe is provided, and this inclined plate 11 is formed with a communication port 13 for drain passage that opens from the center to the lower end side. A slit-shaped vent hole is formed at the upper end edge of the plate and communicates the inside of the joint pipe in the vertical direction, and a connection part with the drainage horizontal branch pipe is provided below the inclined plate.
（作用）
本発明によれば、立管を流下してきた排水は、
継手管内部の傾斜板に衝突し、その流下速度を減
じる。そして、排水は、傾斜板の傾斜に沿つて流
れ、且つ、その連通口を通過して下方に流れる。
このとき、連通口はその下端側に開口しているの
で、傾斜板に沿つて流れる排水の大半は、該連通
口の下端側から管内壁面をつたつて流れる。(Function) According to the present invention, the wastewater flowing down the standpipe is
It collides with the inclined plate inside the joint pipe, reducing its flow velocity. The drainage water flows along the slope of the inclined plate and flows downward through the communication port.
At this time, since the communication port is open at its lower end, most of the waste water flowing along the inclined plate flows from the lower end of the communication port along the inner wall surface of the pipe.
即ち、排水は、傾斜板を通過するとその大半
が、管壁内面に沿つて流下するようになるので、
管中央部に空気層が形成され、排水が管内部を閉
鎖することがなくなり、一管式配管の欠点を解消
する。 In other words, when the wastewater passes through the inclined plate, most of it flows down along the inner surface of the pipe wall.
An air layer is formed in the center of the pipe, preventing drainage from closing the inside of the pipe, eliminating the drawbacks of single-pipe piping.
また、排水が多量に流下してきたとき、該排水
が連通口を閉鎖し、管内圧力変動を大きくするお
それがあるが、本発明では、傾斜板の上端縁に通
気口を有しているので、管の閉鎖が防止され、大
きな圧力変動を防止する。 Furthermore, when a large amount of drainage water flows down, there is a risk that the drainage water may close the communication port and increase pressure fluctuations within the pipe. This prevents tube closure and prevents large pressure fluctuations.
さらに、傾斜板の下方に横枝管接合部を設けて
いるので、排水が接合部に入り込むことがない。 Furthermore, since the horizontal branch pipe joint is provided below the inclined plate, drainage water will not enter the joint.
そして、傾斜板は馬蹄形をしているので、接合
部を三方に設けることができる。 Since the inclined plate has a horseshoe shape, joints can be provided on three sides.

る。 Inside the enlarged diameter portion 8 of each of the upper piping member 2 and the lower piping member 3, there is a pair of inclined plates 11 spaced apart in the axial direction, which divert the flow of fluid falling down the drainage standpipe in the radial direction. , 12 are provided. The upper inclined plate 11 extends and expands downward along the inner wall surface of the enlarged diameter part at an angle with respect to the 8-axis center of the enlarged diameter part, with the uppermost part of the opening of the upper lateral branch pipe joint part 9 as the starting point of the upper part. It traverses the diameter section 8. That is, it extends from three sides of the inner wall of the tube toward the center of the tube, and slopes downward toward the remaining inner wall of the tube. This inclined plate 11 has a notch in the center thereof through which drainage passes downward, and this notch allows the inclined plate 1 to
A communication port 13 is formed that communicates the inner space of the enlarged diameter portion partitioned by 1. A vent hole 14 is provided at the upper end edge of this inclined plate 11, passing through it vertically and communicating with the large-diameter inner space partitioned by the inclined plate 11.

流れを変向させられ流下速度が減速される。 According to the above-mentioned embodiment of the present invention, the drainage water flowing vertically from the drainage standpipe through the upper standpipe joint 5 into the enlarged diameter section 8 hits the inclined plate 11 and diverts the flow in the radial direction. flow rate is reduced. Most of the wastewater that hits the inclined plate 11 and is decelerated and flows down through the communication port 13 hits the inclined surface portion 12' of the inclined plate 12, and the flow direction is changed to the opposite radial direction and flows down. The speed is further reduced. In addition, a portion of the drainage water that does not hit the inclined plate 11 but flows down vertically through the communication port 13 also hits the inclined surface portion 12', and the flow is diverted in the radial direction and the flowing speed is reduced.
このように排水立管から拡径部８に流入した排

However, the enlarged diameter portion 8 is not limited to a circular cross section, but may be rectangular or elliptical. Furthermore, as shown in FIG. 7, the upper part of the upper inclined plate 11 may start from the upper part of the tapered part 7. Further, as shown in FIG. 8, the inclined plates 11 and 12 may be curved along the water flow to prevent water from splashing up. When there are multiple upper lateral branch pipe joints 9, the arrangement of the joints 9 and the inclined plate 11 is as shown in FIGS. 9 and 10.
Arranged as shown.
（発明の効果）
本発明によれば、傾斜板により排水流下速度が
減速されると共に、排水が管内壁に沿つて流下す

ラツプの破れる惧れはない。(Effects of the Invention) According to the present invention, the sloping plate reduces the speed of drainage and the drainage flows down along the inner wall of the pipe, so the pressure inside the pipe does not increase and there is no risk of the water seal trap breaking. There isn't.

る。 In addition, since the horizontal branch pipe is connected below the inclined plate extending from three sides of the inner wall of the pipe, the wastewater that is diverted to the remaining inner wall of the pipe does not enter the side branch pipe, and the water seal becomes dirty and bad odors occur. This can be prevented from occurring. Further, since a vent hole is provided at the upper edge of the inclined plate, the inside of the pipe is prevented from being sealed due to drainage, and large pressure fluctuations are prevented. Since the inclined plate has a horseshoe shape, joints can be provided on three sides.
