Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は排水桝に関し、特に例えば下水道配管等に
用いられる、排水桝に関する。Description: TECHNICAL FIELD The present invention relates to a drainage basin, and more particularly, to a drainage basin used for, for example, sewer pipes.
従来の排水桝１では、第12図に示すように、その軸線
が流出管２の軸線に対して45度の角度で交わるように流
入管３および４が形成され、これらの流入管３および４
に継手５あるいは６等を接着することによって、90度分
岐あるいは45度分岐等を形成するようにしていた。In the conventional drainage basin 1, as shown in FIG. 12, the inflow pipes 3 and 4 are formed so that their axes intersect at 45 degrees with the axis of the outflow pipe 2, and these inflow pipes 3 and 4 are formed.
The joints 5 and 6 are bonded to each other to form a 90-degree branch or a 45-degree branch.
なお、この排水桝１において、流入管３および４の軸
線を流出管２の軸線に対して傾斜（45度）させたのは、
流入管３および４相互での排水を流入を防止するためで
ある。The reason why the axis of the inflow pipes 3 and 4 is inclined (45 degrees) with respect to the axis of the outflow pipe 2 in the drainage basin 1 is as follows.
This is to prevent inflow of drainage between the inflow pipes 3 and 4.
この従来の排水桝１においては、流入管３あるいは４
に接着す継手の種類を変更することによって分岐角度を
変更するようにしていた。しかし、これらの継手を工場
内で接着する場合には、現場の施工状況に応じて分岐角
度を変更することができないという問題点があった。一
方、現場で接着する場合には、接着後２〜３時間以上の
養生が必要なので、その間は次の接続ができず、施工性
が悪いという問題点があった。In this conventional drainage basin 1, the inflow pipe 3 or 4
The branch angle was changed by changing the type of the joint to be bonded to the joint. However, when these joints are bonded in a factory, there has been a problem that the branch angle cannot be changed according to the construction situation at the site. On the other hand, when bonding is performed on site, curing is required for 2 to 3 hours or more after bonding, so that the next connection cannot be performed during that time, and there is a problem that workability is poor.
それゆえに、この発明の主たる目的は、現場において
分岐角度を変更でき、しかも、施工性を向上できる、排
水桝を提供することである。Therefore, a main object of the present invention is to provide a drainage basin capable of changing a branch angle on site and improving workability.
この発明は、流出管、およびその軸線が流出管の軸線
に対して45度の角度で交わる流入管を備える排水桝にお
いて、流入管に、回動によって受口部の流入角度が変わ
る受口部を回動自在に取り付けたことを特徴とする、排
水桝である。The present invention relates to a drainage basin having an outflow pipe and an inflow pipe whose axis intersects with the axis of the outflow pipe at an angle of 45 degrees. This is a drainage basin characterized by being rotatably mounted.
流入管は、その軸線が流出管の軸線に対して45度の角
度で交わるように形成される。そして、この流入管に
は、回動によって受口部の流入角度が変わる受口管が取
り付けられる。たとえば、流出管の軸線に対して22.5度
の角度で傾斜する接合面を有して流入管に受口管を取り
付けると、受口管を回動することによって、受口部の流
入角度を45度〜90度の間で変更できる。The inlet pipe is formed such that its axis intersects the axis of the outlet pipe at a 45 degree angle. Then, a receiving pipe is attached to the inflow pipe, the rotation of which changes the inflow angle of the receiving section. For example, when a receiving pipe is attached to an inflow pipe with a joint surface inclined at an angle of 22.5 degrees with respect to the axis of the outflow pipe, the inflow angle of the receiving section is reduced by rotating the receiving pipe. Can be changed between degrees and 90 degrees.
この発明によれば、受口部を回動することによって、
現場において受口部の流入角度すなわち分岐角度を変更
することができる。According to the present invention, by rotating the receiving portion,
It is possible to change the inflow angle, that is, the branch angle of the receptacle at the site.
しかも、流入管と受口管とは接着剤を用いることなく
機械的に接合されるので、従来のような２〜３時間以上
もの養生時間を待つ必要がなく、したがって、施工性を
向上できる。Moreover, since the inflow pipe and the receiving pipe are mechanically joined without using an adhesive, there is no need to wait for a curing time of two to three hours or more as in the conventional case, and therefore, the workability can be improved.
また、流入管は、その桝本体との接合部における軸線
が、流出管の軸線に対して45度の角度で交わるように形
成されるので、分岐角度をたとえば90度に設定した場合
でも、流入管相互の排水の流入は生じない。In addition, since the inflow pipe is formed so that the axis at the joint with the box body intersects the axis of the outflow pipe at an angle of 45 degrees, even when the branch angle is set to 90 degrees, for example, No inflow of drainage between pipes occurs.
