【考案の詳細な説明】
本考案は90゜エルボに関するものである。従来、
この種エルボは規格品として市販されており第１
図に示す如く、排水管４を嵌受する受筒１′の端
部１１′から流出管を接続する継筒２′の軸線
O′までの距離L′が前記受筒１′の長さl′と継筒
２′の内径D″の半分をプラスした距離よりも大き
い。即ち規格化されたエルボはL′＞D″／２＋l′の関
係にあり、受筒１′の管径D′に対して流れ軸線
S′の曲率半径が大きいものである。[Detailed description of the invention] The present invention relates to a 90° elbow. Conventionally,
This type of elbow is commercially available as a standard product and is the first
As shown in the figure, the axis of the connecting tube 2' that connects the outflow pipe from the end 11' of the receiving tube 1' in which the drain pipe 4 is fitted
The distance L' to O' is greater than the sum of the length l' of the receiving tube 1' and half the inner diameter D'' of the joint tube 2'.In other words, the standardized elbow is L'>D''/ There is a relationship of 2+l', and the flow axis is
The radius of curvature of S' is large.

ていた。 Therefore, to explain the case where this elbow is used in the trap shown in Fig. 4, 6 in the figure is the trap main body, which consists of a pocket 61 and an invert 62, and the sewage flowing from the drain pipe 4 flows into the trap 6.
1, the overflow from the overflow weir 63 is drained to the invert 62 and then to the sewer, and in order to have a trap function, it is connected to the drain pipe 4 inserted from the side wall of the adjuster star 7 using an elbow. The tip 51 of the tube 5 is positioned below the water surface of the pocket 61. At this time, in the conventional standardized elbow, the pocket opening of the trap is narrow and the radius of curvature of the flow axis is large relative to the pipe diameter D' of the receiving tube 1', so the vertical pipe 5 to be connected is placed inside the pocket opening. It was difficult to carry out construction in a narrow space as the water did not settle down and came into contact with an overflow weir. Furthermore, when the diameter of the drain pipe is made thinner and the radius of curvature is made smaller in order to facilitate construction, the pipe does not have enough capacity to handle the amount of wastewater from the kitchen or bath, causing problems such as clogging.
本考案は以上のような点に鑑み改良されたもの
で、その目的とするところは、家庭雑排水の排水
量を処理するのに充分な管径の排水管を使用し、
かつ、受筒の長さｌを短かくすることなく先端か
ら継筒の軸線Ｏまでの距離を短かくして、流れ軸
線の曲率半径を小さくし、狭い場所での配管施工
の容易なエルボを提供するものである。 The present invention has been improved in view of the above points, and its purpose is to use a drain pipe with a diameter sufficient to treat the amount of domestic gray water,
In addition, the distance from the tip to the axis O of the joint tube is shortened without shortening the length l of the receiving tube, thereby reducing the radius of curvature of the flow axis, thereby providing an elbow that allows easy piping construction in narrow spaces. It is something.

ることを特徴とするものである。 That is, the present invention integrates a drain pipe receiving pipe 1 with a length l and an inner diameter D 1 into which a drain pipe 4 is fitted, and an outflow pipe joint pipe 2 with an inner diameter D 2 at an angle of 90° via a bent pipe 3. The outer peripheral wall 12 at the base end of the drain pipe receiver 1
A part of the receiving sleeve 1 contacts a part of the base 21 of the outflow pipe joint 2, and the base end 13 of the receiving pipe 1 protrudes toward the central axis O side from the inner circumferential wall of the outflow pipe joint 2 at the corresponding contact part. It is characterized by:
第２図は排水管受筒１と流出管継筒２の内径が
D1＝D2の関係にあるものを示す。 Figure 2 shows the inner diameters of the drain pipe receiver 1 and the outlet pipe joint 2.
Indicates the relationship D 1 = D 2 .
本考案は特に排水管受筒１の端部１１から流出
管継筒２の中心軸線Ｏまでの距離Ｌとして次式
ｌ／２＋D2／２＜Ｌ＜ｌ＋D2／２，ｌ＜D2／２
50mm≦D1＝D2≦100mm
の関係を有するものである。 In this invention, the distance L from the end 11 of the drain pipe receiver 1 to the central axis O of the outflow pipe joint 2 is calculated by the following formula: l/2+D 2 /2<L<l+D 2/2 , l<D 2/2 The relationship is 50mm≦D 1 =D 2 ≦100mm.
即ち、本考案は家庭からの雑排水を処理するの
に充分な管径として50〜100mmの排水管を使用し、
この受筒１の内径D1に対して流れ軸線Ｓの曲率
半径を小さくすることができたものである。 That is, the present invention uses a drain pipe with a diameter of 50 to 100 mm, which is sufficient to treat gray water from a household.
The radius of curvature of the flow axis S can be made smaller with respect to the inner diameter D1 of the receiving tube 1.

できるようになつた。 An example of the use of the elbow of this invention in a trap manhole is shown in Figure 4. As already explained about the trap manhole, when the elbow of this invention is used in this trap manhole, there is no problem with the construction that occurs with the conventional standard elbow, that is, the connected vertical pipe 5 does not fit in the pocket 61 and comes into contact with the overflow weir 63, and the flow rate is not hindered and the elbow can be positioned almost in the center of the pocket opening.
本考案は叙述のように排水管受筒の基端部の外
周壁の一部が流出管継筒の基部の一部に当接し、
該受筒の基端を該当接部における流出管継筒の内
周壁より中心軸線Ｏ側に突出させることにより流
れ軸線の曲率半径を小さくすることができる。 As described above, in the present invention, a part of the outer circumferential wall of the base end of the drain pipe receiving pipe abuts a part of the base of the outflow pipe joint pipe,
The radius of curvature of the flow axis can be made smaller by causing the base end of the receiving tube to protrude toward the center axis O side from the inner circumferential wall of the outflow pipe joint tube at the corresponding contact portion.
又、トラツプ桝に使用した場合でも、排水管を
細くすることなく、排水容量に充分な管径を維持

易となると共に排水管の嵌合保持性も良好であ
る。 In addition, even when used in a trap box, the drain pipe can be maintained at a diameter sufficient for the drainage capacity without making it thinner, and the outflow pipe ( The distance to the center axis of the vertical pipe (vertical pipe) can be shortened, making piping construction easier and retaining the fit of the drain pipe better.
