Description

本発明は、排水ヘッダーを構成し、側管部から主管部への汚水の排水性を向上する管継手に関する。 The present invention relates to a pipe joint that constitutes a drainage header and improves the drainage of sewage from the side pipe portion to the main pipe portion.

従来、建物の床下等に配設し、浴室、洗面化粧台及びキッチン等における生活排水の排出起点から伸びる排水枝管を上流側に接続し、建物の基礎を貫通して引いた排水主管を下流接続することにより、生活排水を上記上流側から下流側に連結し、屋外の所定の位置に排水を行う排水ヘッダーが用いられている。 Conventionally, the drainage branch pipe that is placed under the floor of the building and extends from the discharge starting point of domestic wastewater in the bathroom, vanity, kitchen, etc. is connected to the upstream side, and the drainage main pipe drawn through the foundation of the building is downstream. By connecting, a drainage header is used in which domestic wastewater is connected from the upstream side to the downstream side and drained to a predetermined position outdoors.

上記排水ヘッダーの一部には、内部の排水性を向上するよう構成されたものが存在する。特許文献1(特開平8-13562号公報)には、単位体中のT字状管において、楕円形管内の連通部に整流翼を付設し、この整流翼を楕円管連通部の上流側で固定して下流側を遊離させることにより、整流翼によって流れが誘導される。これにより、上流側で流される汚水を円滑に排水可能な壁排水会合管用単位体が開示されている。 Some of the drainage headers are configured to improve internal drainage. In Patent Document 1 (Japanese Unexamined Patent Publication No. 8-13562), in the T-shaped tube in the unit body, a rectifying blade is attached to the communication portion in the elliptical tube, and the rectifying blade is attached to the upstream side of the elliptical tube communication portion. By fixing and freeing the downstream side, the flow is guided by the rectifying blade. Thereby, a unit body for a wall drainage meeting pipe capable of smoothly draining sewage flowing on the upstream side is disclosed.

また、特許文献2(特開2005-2651号公報)には、汚物用枝管接続部のヘッダー本管への連結口の内周面に、その内径側に張り出る偏流ガイドを設けた排水ヘッダーにより、汚物用枝管接続部から流入した汚物の掃流性を向上可能とする排水用ヘッダーが開示されている。 Further, in Patent Document 2 (Japanese Unexamined Patent Publication No. 2005-2651), a drainage header provided with a drift guide protruding toward the inner diameter side on the inner peripheral surface of the connection port to the header main of the branch pipe connection portion for filth. Discloses a drainage header that makes it possible to improve the sweepability of the sewage that has flowed in from the sewage branch pipe connection portion.

しかしながら、上記特許文献1の壁排水会合管用単位体では、整流翼の下流側が遊離しているため、重量が大きな固形物は直進してしまい、楕円管内で停滞するおそれがあった。また、特許文献2の排水用ヘッダーでは、汚物用枝管接続部に配設された偏流ガイドでは、汚物用枝管接続部の内部を流れる汚物の一部はヘッダー本管の下流側に誘導できるが、流量が多い場合には高い掃流性の向上は望めない。 However, in the unit body for the wall drainage meeting pipe of Patent Document 1, since the downstream side of the rectifying blade is free, a solid material having a large weight may go straight and stagnant in the elliptical pipe. Further, in the drainage header of Patent Document 2, a part of the filth flowing inside the filth branch pipe connection portion can be guided to the downstream side of the header main pipe by the drift guide provided at the filth branch pipe connection portion. However, when the flow rate is large, high improvement in sweepability cannot be expected.

ここで、排水ヘッダーの構造に着目すると、側管部から主管部に流入する汚水を主管部の下流側に確実に誘導可能な構造を備えていないことは明らかであって、未だ改善の余地があった。 Focusing on the structure of the drainage header, it is clear that it does not have a structure that can reliably guide the sewage flowing from the side pipe to the downstream side of the main pipe, and there is still room for improvement. there were.

そこで、本発明は、上記問題に鑑みて創造されたものであり、側管部から主管部に流入する汚水を主管部の下流側に誘導し、排水ヘッダーの排水性を好適に向上可能な管継手を提供することを目的とする。 Therefore, the present invention was created in view of the above problems, and is a pipe capable of guiding the sewage flowing from the side pipe portion to the main pipe portion to the downstream side of the main pipe portion and preferably improving the drainage property of the drainage header. The purpose is to provide fittings.

このような構成を有する本発明の管継手では、側管部から主管部内に流入する汚水を、排水案内部を構成する排水遮断部及び排水支持部によって適切に案内し、汚水を円滑に主管部の下流側へ誘導して排水性を向上することができる。また、排水案内部が主管部の管底と離間して設けられているため、主管部の管底近傍が排水支持部に遮られることがなく主管部を流れる汚水が堰き止められない。また、重量が大きい固形物は管底を進むため、進路を確実に確保することができる。 In the pipe joint of the present invention having such a configuration, the sewage flowing from the side pipe portion into the main pipe portion is appropriately guided by the drainage cutoff portion and the drainage support portion constituting the drainage guide portion, and the sewage is smoothly guided to the main pipe portion. It can be guided to the downstream side of the water to improve drainage. Further, since the drainage guide portion is provided apart from the pipe bottom of the main pipe portion, the vicinity of the pipe bottom of the main pipe portion is not blocked by the drainage support portion, and the sewage flowing through the main pipe portion cannot be blocked. In addition, since the heavy solid matter travels on the bottom of the pipe, a course can be reliably secured.

また、上記の本発明の管継手においては、
前記排水支持部が、前記主管部の下流側に向かって下方向に傾斜する傾斜面を具備し、
前記排水支持部の下流側の端縁が、前記側管部の下端より下方に位置することが望ましい。
Further, in the above-mentioned pipe joint of the present invention,
The drainage support portion includes an inclined surface that inclines downward toward the downstream side of the main pipe portion.
It is desirable that the downstream end edge of the drainage support portion is located below the lower end of the side pipe portion.

このような構成を有する本発明の管継手では、側管部から主管部内に流入する汚水をより円滑に主管部の下流側に案内することができるため、一層排水性を向上することができる。 In the pipe joint of the present invention having such a configuration, the sewage flowing from the side pipe portion into the main pipe portion can be more smoothly guided to the downstream side of the main pipe portion, so that the drainage property can be further improved.

また、上記の本発明の管継手においては、
前記主管部が、上部に点検口を具備し、
平面視で、前記点検口と、少なくとも前記排水案内部の一部と、が重なっていることが望ましい。
Further, in the above-mentioned pipe joint of the present invention,
The main section is provided with an inspection port at the top and has an inspection port.
It is desirable that the inspection port and at least a part of the drainage guide portion overlap with each other in a plan view.

このような構成を有する本発明の管継手では、点検口から排水案内部近傍での固形物等の異物詰りを容易に目視確認することやメンテナンス用の治具を挿入することができ、容易にメンテナンスを実行することができる。 In the pipe joint of the present invention having such a configuration, it is possible to easily visually check for foreign matter clogging such as solid matter in the vicinity of the drainage guide portion from the inspection port, and to insert a jig for maintenance easily. Maintenance can be performed.

また、上記の本発明の管継手においては、更に、
前記排水案内部を前記側管の管軸方向の上流側から見たときに、前記排水案内部の端部が、前記主管部の下流側に向かって斜めに形成されていることが望ましい。
Further, in the above-mentioned pipe joint of the present invention, further
When the drainage guide portion is viewed from the upstream side in the pipe axis direction of the side pipe portion , it is desirable that the end portion of the drainage guide portion is formed obliquely toward the downstream side of the main pipe portion.

このような構成を有する本発明の管継手では、側管部から主管部内に流入する汚水が多量になっても、上方(厳密には側管部内から主管部を正面視した状態で下流側上方)が開口されるため、汚水が排水案内部を越流して排水案内部の上方から主管部の底面に導水されることが可能であるため排水案内部が側管部から主管部内に流入する汚水の停滞を防止できるとともに、主管部の下流側に誘導しやすくすることができる。更に、重量の大きい固形物が側管部から主管部内に流入する際、固形物は管底を移動するため排水案内部の形状に沿って主管部の下流側に案内することができる。すなわち、このような構成を有する本発明の管継手では、排水の停滞を防止する効果と固形物を主管部の下流側に円滑に案内する効果の両方を奏することができる。 In the pipe joint of the present invention having such a configuration, even if a large amount of sewage flows from the side pipe portion into the main pipe portion, the upper side (strictly speaking, the downstream side upper side with the main pipe portion viewed from the inside of the side pipe portion). ) Is opened, so that sewage can flow over the drainage guide and be guided from above the drainage guide to the bottom of the main pipe, so that the drainage guide flows into the main pipe from the side pipe. It is possible to prevent stagnation and facilitate guidance to the downstream side of the main pipe. Further, when a heavy solid matter flows from the side pipe portion into the main pipe portion, the solid matter moves on the bottom of the pipe and can be guided to the downstream side of the main pipe portion along the shape of the drainage guide portion. That is, the pipe joint of the present invention having such a configuration can exhibit both the effect of preventing the stagnation of drainage and the effect of smoothly guiding the solid matter to the downstream side of the main pipe portion.

本発明により、側管部から主管部に流入する汚水を主管部の下流側に誘導し、排水ヘッダーの排水性を好適に向上可能な管継手を提供することができる。 INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a pipe joint capable of guiding the sewage flowing from the side pipe portion to the main pipe portion to the downstream side of the main pipe portion and preferably improving the drainage property of the drainage header.

1.排水ヘッダー1001及び管継手1の概要
図1を用いて、本実施形態の管継手1により構成される排水ヘッダー1001の概要について説明する。図1は、本実施形態の管継手1で構成した排水ヘッダー1001の概要を説明する斜視図である。
1. 1. Outline of the drainage header 1001 and the pipe joint 1 The outline of the drainage header 1001 configured by the pipe joint 1 of the present embodiment will be described with reference to FIG. FIG. 1 is a perspective view illustrating an outline of a drainage header 1001 configured by a pipe joint 1 of the present embodiment.

排水ヘッダー1001は、建物の床下等に配設して使用する排水用具であって、浴室、洗面化粧台及びキッチン等からの生活排水の排出起点から伸びる排水枝管を上流側に接続し、建物の基礎を貫通して引いた排水主管を下流側に接続することにより、生活排水を上流側から下流側に流して屋外に排出させるものである。 The drainage header 1001 is a drainage tool used by arranging it under the floor of a building, etc., and connects a drainage branch pipe extending from the discharge starting point of domestic wastewater from a bathroom, a vanity, a kitchen, etc. to the upstream side of the building. By connecting the drainage main pipe drawn through the foundation of the building to the downstream side, domestic wastewater is drained from the upstream side to the downstream side and discharged to the outside.

排水ヘッダー1001を用いた排水システムを採用することによって、排出起点から排水ヘッダー1001に生活排水を集約でき、排水桝の配設数を大幅に削減して、建築のイニシャルコストを効果的に低減可能となる。また、屋外において、排水桝には、汚物の滞留等に起因する詰まり等のトラブルを解決するためのメンテナンス口(点検口)を配設する必要があるため、排水桝の配設数そのものが減れば、建物周辺のメンテナンス口の数も減り、美観を損なわなくて済む。 By adopting a drainage system using the drainage header 1001, domestic wastewater can be collected from the drainage starting point to the drainage header 1001, the number of drainage basins can be significantly reduced, and the initial cost of construction can be effectively reduced. It becomes. In addition, since it is necessary to dispose a maintenance port (inspection port) in the drainage basin outdoors to solve problems such as clogging caused by the retention of filth, the number of drainage basins arranged can be reduced. If this is the case, the number of maintenance openings around the building will be reduced, and the appearance will not be spoiled.

本実施形態の排水ヘッダー1001は、図1に示すように、4つの管継手1を一列に並べ、互いに隣接する管継手1の接続部同士を接着剤で結合して接続すると共に、排水主管接続部1003a,1003bを具備する端部閉塞材1005a,1005bのそれぞれの接続部を上記と同様に接着剤で結合して、上流側及び下流側の両端に位置する管継手1に接続して構成したものである。 In the drainage header 1001 of the present embodiment, as shown in FIG. 1, four pipe joints 1 are arranged in a row, and the connection portions of the pipe joints 1 adjacent to each other are connected by being bonded with an adhesive, and the drainage main pipe is connected. The connection portions of the end closing members 1005a and 1005b provided with the portions 1003a and 1003b are connected with an adhesive in the same manner as described above, and are connected to the pipe joints 1 located at both ends on the upstream side and the downstream side. It is a thing.

本実施形態の管継手1は排水ヘッダー1001の主な構成部材であり、建物の排水起点から伸びる排水枝管の数に応じた数の管継手1を接続して、排水ヘッダー1001を構成する。即ち、管継手1は、排水ヘッダー1001の性能を根幹で担保するものであり、備える構造によって排水ヘッダー1001の排水性を大きく左右する重要な部材である。 The pipe joint 1 of the present embodiment is a main component of the drainage header 1001, and the drainage header 1001 is formed by connecting a number of pipe joints 1 corresponding to the number of drainage branch pipes extending from the drainage starting point of the building. That is, the pipe joint 1 is an important member that guarantees the performance of the drainage header 1001 at its core and greatly affects the drainage property of the drainage header 1001 depending on the structure provided.

2.管継手1の構造
続いて、図2~図6を用いて、本実施形態における管継手1の構造について詳細に説明する。なお、本実施形態では、図2に示すように、主管部3の上流側X1から下流側X2(主管部3の管軸方向)を方向X、主管部3に対する側管部5側を方向Y、また上下(主管部3の管軸に対して鉛直方向)を方向Zとする。
2. 2. Structure of Pipe Fitting 1 Subsequently, the structure of pipe fitting 1 in the present embodiment will be described in detail with reference to FIGS. 2 to 6. In this embodiment, as shown in FIG. 2, the direction X is from the upstream side X1 of the main pipe portion 3 to the downstream side X2 (the pipe axis direction of the main pipe portion 3), and the direction Y is the side pipe portion 5 side with respect to the main pipe portion 3. Further, the vertical direction (vertical direction with respect to the pipe axis of the main pipe portion 3) is defined as the direction Z.

ここで、図2は、本実施形態における管継手1の斜視図であり、図3は本実施形態における管継手1を下流側X2から見た側面図である。図4は、本実施形態における管継手1を主管部3内から側管部5側を見た断面図である。図5(a)及び(b)は、本実施形態における管継手1の構造を示す図であって、図5(a)は、点検口15上方から本実施形態の管継手1を見下ろした平面図であり、図5(b)は、図3に示す矢視Aの断面図である。 Here, FIG. 2 is a perspective view of the pipe joint 1 in the present embodiment, and FIG. 3 is a side view of the pipe joint 1 in the present embodiment as viewed from the downstream side X2. FIG. 4 is a cross-sectional view of the pipe joint 1 in the present embodiment as viewed from the inside of the main pipe portion 3 to the side pipe portion 5. 5 (a) and 5 (b) are views showing the structure of the pipe joint 1 in the present embodiment, and FIG. 5 (a) is a plan view looking down on the pipe joint 1 of the present embodiment from above the inspection port 15.

At the other end, a third connection portion 21 to which a drainage pipe extending from each drainage starting point of the building can be connected is formed (see particularly FIGS. 2 and 5). In the present embodiment, the side pipe portion 5 has a straight pipe shape but may have a curved pipe shape, and the pipe axis of the side pipe portion 5 is perpendicular to the pipe axis of the main pipe portion 3, but the main pipe It may be formed diagonally toward the downstream side of the portion 3.

なお、上述した主管部3及び側管部5の各部のサイズは、使用する建物の規模や排水量に応じて最適化できることが好ましい。よって、上記各部のサイズ違いで構成した複数種の管継手1を提供し、使用者が選択により最適化した排水ヘッダー1001を構成可能とすることが望ましい。 It is preferable that the sizes of the main pipe portion 3 and the side pipe portion 5 described above can be optimized according to the scale of the building to be used and the amount of drainage. Therefore, it is desirable to provide a plurality of types of pipe joints 1 configured by different sizes of the above parts so that the drainage header 1001 optimized by the user can be configured.

<点検口15の構造>
点検口15は、上述の主管部3の上方に配設された略円形の孔であって、主管部3の上方から下方に向かって主管部3の内外を方向Zに連通するものである。具体的な形成位置は、本実施形態の管継手1を上方から方向Zの下方に平面視した状態において、主管部3の管軸(方向X)と、側管部5の管軸(方向Y)と、が交差する位置を中心とし、所定の直径で形成することが望ましい。なお、点検口15は、別個に用意した蓋(図示せず)を嵌合させるため、例えば端縁に螺子山形成等を行えばよい。
<Structure of inspection port 15>
The inspection port 15 is a substantially circular hole arranged above the main pipe portion 3 described above, and communicates the inside and outside of the main pipe portion 3 in the direction Z from the upper side to the lower side of the main pipe portion 3. The specific forming positions are the pipe axis (direction X) of the main pipe portion 3 and the pipe shaft (direction Y) of the side pipe portion 5 in a state where the pipe joint 1 of the present embodiment is viewed in a plan view from above to the bottom of the direction Z. It is desirable to form it with a predetermined diameter centered on the position where) and In addition, in order to fit a separately prepared lid (not shown) into the inspection port 15, for example, a screw thread may be formed on the end edge.

<排水案内部7の構造>
排水案内部7は、上述した主管部3と側管部5(他方の端部側)とが接続された内部(合流口)に配設され、上述のとおり側管部5からの汚水を主管部3の下流側X2に誘導するものである。この排水案内部7は、本実施形態の管継手1が具備する特徴的な部位であり、この排水案内部7を具備することにより、従来と比較して、側管部5から主管部3に侵入した汚水(固形物を含む。)の流水方向を、より確実に主管部3の下流側X2に向けることができ、上記汚水を主管部3に誘導するものである。
<Structure of drainage guide 7>
The drainage guide portion 7 is arranged inside (the confluence) where the main pipe portion 3 and the side pipe portion 5 (the other end side) are connected, and the sewage from the side pipe portion 5 is mainly piped as described above. It guides to the downstream side X2 of the part 3. The drainage guide portion 7 is a characteristic portion provided in the pipe joint 1 of the present embodiment, and by providing the drainage guide portion 7, from the side pipe portion 5 to the main pipe portion 3 as compared with the conventional case. The flow direction of the invaded sewage (including solid matter) can be more reliably directed to the downstream side X2 of the main pipe portion 3, and the sewage is guided to the main pipe portion 3.

排水案内部7は、略上方に位置する排水遮断部9と、排水遮断部9の下方に一体的に形成された排水支持部11と、を具備する。より具体的には、排水遮断部9は、側管部5から誘導された汚水の流水方向を、主管部3の上流側X1及び直進方向(主管部3の内部側面側)と異なる方向ではなく、主管部3の下流側X2に向けて強制的に誘導し、かつ方向Yへの汚水の直進を妨げて阻止乃至は抑制するようにする。また、排水支持部11は、側管部5から主管部3に侵入した汚水を下方から支持して受け止め、主管部3の下流側X2に向けて強制的に誘導する。 The drainage guide portion 7 includes a drainage cutoff portion 9 located substantially above and a drainage support portion 11 integrally formed below the drainage cutoff portion 9. More specifically, the drainage cutoff portion 9 does not make the flow direction of the sewage induced from the side pipe portion 5 different from the upstream side X1 of the main pipe portion 3 and the straight direction (inner side surface side of the main pipe portion 3). , Forcibly guide the sewage toward the downstream side X2 of the main pipe portion 3 and prevent the sewage from going straight in the direction Y to prevent or suppress it. Further, the drainage support portion 11 supports and receives the sewage that has entered the main pipe portion 3 from the side pipe portion 5 from below, and forcibly guides the sewage toward the downstream side X2 of the main pipe portion 3.

排水遮断部9は、側管部5と主管部3との合流口の上流側X1の端縁近傍で、略方向Zに立ち上がる壁状部位であって、主管部3内で方向Xに対向している。また、側管部5の断面に沿って合流口から主管部3内に突出(方向Y)しているため、上流側X1に膨れる曲面状に形成され、下方で排水支持部11と繋がっている。なお、排水遮断部9の上端の位置は、主管部3内側の天面と接触しない程度に留められている。 The drainage cutoff portion 9 is a wall-shaped portion that rises in the substantially direction Z near the edge of the upstream side X1 of the confluence of the side pipe portion 5 and the main pipe portion 3, and faces the direction X in the main pipe portion 3. ing. Further, since it protrudes into the main pipe portion 3 from the confluence along the cross section of the side pipe portion 5 (direction Y), it is formed in a curved surface shape that swells on the upstream side X1 and is connected to the drainage support portion 11 below. .. The position of the upper end of the drainage cutoff portion 9 is kept so as not to come into contact with the top surface inside the main pipe portion 3.

更に、側管部5から流れてきた汚水の方向Yへの直進による主管部3への流入を妨げるように、側管部5と主管部3との合流口に対向するよう排水遮断部9が曲面で回り込んで形成されている(特に図3~6参照)。なお、側管部5から主管部3内に流入する汚水が多量となる場合は、汚水が排水遮断部9を越流して方向Yに直進する場合があるが、固形物は側管部5の管底近傍を進み、汚水は側管部5の管上方を進むため、適切に主管部3内に流入させることができる。 Further, the drainage cutoff portion 9 faces the confluence of the side pipe portion 5 and the main pipe portion 3 so as to prevent the inflow of the sewage flowing from the side pipe portion 5 into the main pipe portion 3 by going straight in the direction Y. It is formed by wrapping around a curved surface (see especially FIGS. 3 to 6). If a large amount of sewage flows from the side pipe portion 5 into the main pipe portion 3, the sewage may overflow the drainage cutoff portion 9 and go straight in the direction Y, but the solid matter is in the side pipe portion 5. Since the sewage travels near the bottom of the pipe and flows above the pipe of the side pipe portion 5, it can be appropriately flowed into the main pipe portion 3.

排水支持部11は、側管部5と主管部3との合流口の下方の端縁近傍で、合流口から主管部3内に突出(方向Y)し、主管部3内から方向Yに合流口を正面視した状態において、方向Zの下方及び下流側X2に向かって傾斜するよう形成された床状部位(傾斜面を有する。)である。また、排水支持部11の上方は、点検口15や主管部3の上部内面まで開放されており、所定の空間が形成されている。これにより、排水案内部7での汚水の滞留を防止することができる。 The drainage support portion 11 projects (direction Y) from the confluence into the main pipe portion 3 near the lower edge of the confluence of the side pipe portion 5 and the main pipe portion 3, and merges in the direction Y from the inside of the main pipe portion 3. It is a floor-like portion (having an inclined surface) formed so as to incline downward in the direction Z and toward the downstream side X2 when the mouth is viewed from the front. Further, the upper part of the drainage support portion 11 is open to the upper inner surface of the inspection port 15 and the main pipe portion 3, and a predetermined space is formed. This makes it possible to prevent the sewage from staying in the drainage guide portion 7.

本実施形態では、排水支持部11の上流側X1は上述した排水遮断部9の下方と繋がっており、排水遮断部9と排水支持部11とが、曲面を有して滑らかな形状となるよう接続されて一体的に形成されている(特に図2~図4参照)。これにより、側管部5から主管部3に流入しようとする汚水が、排水遮断部9に衝突した後、水勢を極力殺さず排水支持部11に誘導される。 In the present embodiment, the upstream side X1 of the drainage support portion 11 is connected to the lower side of the drainage cutoff portion 9 described above, so that the drainage cutoff portion 9 and the drainage support portion 11 have a curved surface and have a smooth shape. They are connected and integrally formed (see particularly FIGS. 2 to 4). As a result, the sewage that is about to flow from the side pipe portion 5 into the main pipe portion 3 is guided to the drainage support portion 11 without killing the water force as much as possible after colliding with the drainage cutoff portion 9.

排水支持部11の下端(傾斜した下流側X2の端部)は、側管部5の下端より下方に位置(離間距離H1)し、かつ主管部3の管底より上方に位置(離間距離H2)することが望ましい(特に図3及び4参照)。これにより、側管部5から主管部3内に流入した汚水を、より円滑に下流側X2に誘導することができる。また、主管部3の管底近傍が排水支持部11で遮られることがないため、主管部3内の上流側X1から下流側X2に流れる汚水が堰き止められず、円滑に排水することができる。更に、重量の大きい固形物は管底を進むため、進路を確実に確保することができる。 The lower end of the drainage support portion 11 (the end of the inclined downstream side X2) is located below the lower end of the side pipe portion 5 (separation distance H1) and above the pipe bottom of the main pipe portion 3 (separation distance H2). ) (Especially see FIGS. 3 and 4). As a result, the sewage that has flowed from the side pipe portion 5 into the main pipe portion 3 can be more smoothly guided to the downstream side X2. Further, since the vicinity of the bottom of the main pipe portion 3 is not blocked by the drainage support portion 11, the sewage flowing from the upstream side X1 to the downstream side X2 in the main pipe portion 3 is not blocked and can be drained smoothly. .. Further, since the heavy solid matter travels on the bottom of the pipe, a course can be surely secured.

主管部3の内部を方向Xに正面視した状態において、排水遮断部9と排水支持部11とにより構成された排水案内部7の先端位置(排水案内部7における主管部3の内側の端部)は、主管部3の断面中心線23と略同一、又は断面中心線23を越えて突出(突出量W1)していることが望ましい(特に図3及び図5(b)参照)。 When the inside of the main pipe portion 3 is viewed from the front in the direction X, the tip position of the drainage guide portion 7 composed of the drainage cutoff portion 9 and the drainage support portion 11 (the inner end portion of the main pipe portion 3 in the drainage guide portion 7). ) Is substantially the same as the cross-section center line 23 of the main pipe portion 3, or protrudes beyond the cross-section center line 23 (protrusion amount W1) (particularly, see FIGS. 3 and 5 (b)).

これにより、排水案内部7の先端位置が、合流口から主管部3内に適切量突出するため、側管部5から主管部3に流入しようとする固形物が排水案内部7に係止して合流口近傍で詰まらせることなく円滑に主管部3内に流入させ、下流側X2に誘導することができる。また、側管部5からの主管部3内に流入する汚水量が多量になった場合においても、合流口近傍で汚水が滞留することなく、円滑に排水することができる。 As a result, the tip position of the drainage guide portion 7 protrudes from the merging port into the main pipe portion 3 by an appropriate amount, so that solid matter that is about to flow into the main pipe portion 3 from the side pipe portion 5 is locked to the drainage guide portion 7. It is possible to smoothly flow into the main pipe portion 3 without clogging in the vicinity of the confluence and guide it to the downstream side X2. Further, even when the amount of sewage flowing into the main pipe portion 3 from the side pipe portion 5 becomes large, the sewage can be smoothly drained without staying in the vicinity of the confluence.

主管部3内部から側管部5を方向Yに正面視した状態において、排水案内部7の下流側X2の端部は、側管部5の内側右壁(合流口右壁)より下流側X2に位置W2していることが望ましい(特に図4参照)。これにより、側管部5から主管部3内に流入する汚水を長距離下流側X2に誘導することができる。 When the side pipe portion 5 is viewed from the inside of the main pipe portion 3 in the front direction Y, the end portion of the downstream side X2 of the drainage guide portion 7 is the downstream side X2 from the inner right wall (merging port right wall) of the side pipe portion 5. It is desirable that the position is W2 (especially see FIG. 4). As a result, the sewage flowing from the side pipe portion 5 into the main pipe portion 3 can be guided to the long-distance downstream side X2.

点検口15を主管部3の上方から下方に平面視した状態において、点検口15から排水案内部7の一部を視認(点検口15内に排水案内部7の一部が重なった状態)できるよう構成されていることが望ましい(特に図5(a)参照)。これにより、点検口15から排水案内部7近傍での固形物等の異物詰りを容易に目視確認することやメンテナンス用の治具を挿入することができ、容易にメンテナンスを実行することができる。 When the inspection port 15 is viewed in a plan view from above to below the main pipe portion 3, a part of the drainage guide portion 7 can be visually recognized from the inspection port 15 (a state in which a part of the drainage guide portion 7 overlaps the inspection port 15). It is desirable that it is configured in such a manner (particularly, see FIG. 5 (a)). As a result, it is possible to easily visually check for foreign matter clogging such as solid matter in the vicinity of the drainage guide portion 7 from the inspection port 15 and insert a maintenance jig, so that maintenance can be easily performed.

側管部5内部から主管部3内を方向Yに正面視した状態において、排水案内部7の端部(主管部3内に突出した先端側)が主管部3の下流側X2に向かって傾斜するよう形成されることが望ましい(特に図6参照)。これにより、側管部5から主管部3内に流入する汚水が多量になっても、上方(厳密には上記正面視において左側上方)が開口されるため、排水案内部7が側管部5から主管部3内に流入する汚水を停滞させず、主管部3の下流側X2に誘導することができる。 When the inside of the main pipe portion 3 is viewed from the inside of the side pipe portion 5 in the front direction Y, the end portion of the drainage guide portion 7 (the tip side protruding into the main pipe portion 3) is inclined toward the downstream side X2 of the main pipe portion 3. It is desirable that it be formed so as to (particularly see FIG. 6). As a result, even if a large amount of sewage flows from the side pipe portion 5 into the main pipe portion 3, the upper side (strictly speaking, the upper left side in the above front view) is opened, so that the drainage guide portion 7 becomes the side pipe portion 5. The sewage flowing into the main pipe portion 3 from the main pipe portion 3 can be guided to the downstream side X2 of the main pipe portion 3 without stagnation.

更に、重量の大きい固形物が側管部5から主管部3内に流入する際、固形物は管底を移動するため排水案内部7の形状に沿って主管部3の下流側X2に向かって斜め下方に誘導することができる。なお、上述した排水案内部7の端部(主管部3内に突出した先端側)は一直線で形成されなくてもよく、上記正面視において左側上方が開口されていればよい。 Further, when a heavy solid matter flows from the side pipe portion 5 into the main pipe portion 3, the solid matter moves toward the downstream side X2 of the main pipe portion 3 along the shape of the drainage guide portion 7 because the solid matter moves at the bottom of the pipe. It can be guided diagonally downward. The end of the drainage guide portion 7 (the tip side protruding into the main pipe portion 3) does not have to be formed in a straight line, and the upper left side may be opened in the front view.

図6に示すとおり、側管部5内部から主管部3内を方向Yに正面視した状態において、合流口(主管部3と側管部5との境界)の中心点から鉛直線(方向Z)及び水平線(方向X)を設けて仮想的に区画(左上方、右上方、左下方及び右下方)した際、右下方の区画全域に排水案内部7が重なる(換言すると、上記正面視で右下方の区画内全てに排水案内部7が重なって見えること。)ことが望ましい。 As shown in FIG. 6, in a state where the inside of the main pipe portion 3 is viewed from the inside of the side pipe portion 5 in the front direction Y, a vertical straight line (direction Z) from the center point of the confluence (boundary between the main pipe portion 3 and the side pipe portion 5). ) And a horizontal line (direction X) are provided to virtually partition (upper left, upper right, lower left and lower right), and the drainage guide 7 overlaps the entire lower right section (in other words, in the above front view). It is desirable that the drainage guide 7 overlaps with the entire lower right section.)

通常、例えばトイレ排水に含まれる固形物は側管部5の管径の半分よりも大きなものが多く、重量の大きい固形物は側管部5の管底付近を進むため、上述の構成とすれば固形物が側管部5から主管部3に流入する際、排水案内部7の上記右下方に接触して、主管部3の下流側X2に進行方向を変更させることができる(Y方向に直進させない)。 Usually, for example, the solid matter contained in the toilet drainage is often larger than half the diameter of the side pipe portion 5, and the heavy solid matter advances near the bottom of the side pipe portion 5, so that the above configuration is adopted. For example, when the solid matter flows from the side pipe portion 5 into the main pipe portion 3, it comes into contact with the lower right side of the drainage guide portion 7 and the traveling direction can be changed to the downstream side X2 of the main pipe portion 3 (in the Y direction). Do not go straight).

主管部3の内部から方向Zに管底を平面視した状態において、排水支持部11の下流側X2の端縁の形状が、主管部3の管軸(方向Xの中心線)に対して斜めに形成され、かつ側管部5側に対向する端縁は主管部3の内部側壁と接続されることが望ましい(特に図5(b)参照)。これにより主管部3の下流側X2に対して排水案内部7が広く開放され、汚水を好適に誘導しつつ固形物の詰りを防止することができる。 The shape of the edge of the downstream side X2 of the drainage support portion 11 is oblique to the pipe axis (center line of the direction X) of the main pipe portion 3 in a state where the pipe bottom is viewed in a plan view from the inside of the main pipe portion 3 in the direction Z. It is desirable that the end edge formed in and facing the side pipe portion 5 side is connected to the inner side wall of the main pipe portion 3 (particularly see FIG. 5 (b)). As a result, the drainage guide portion 7 is widely opened with respect to the downstream side X2 of the main pipe portion 3, and it is possible to prevent clogging of solid matter while appropriately guiding sewage.

以上、本発明の実施形態について図面を参照しつつ説明してきたが、本発明は、これらの実施形態に限定されるものではなく、特許請求の範囲の記載の精神及び教示を逸脱しない範囲でその他の改良例や変形例が存在する。そして、かかる改良例や変形例は全て本発明の技術的範囲に含まれることは、当業者にとっては容易に理解されるところである。 Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to these embodiments and is not limited to the spirit and teaching of the claims. There are improved and modified examples of. It is easily understood by those skilled in the art that all such improvements and modifications are included in the technical scope of the present invention.

3.その他の排水案内部の構造
排水案内部は図7(a)及び(b)に示す変形例のような態様としてもよい。図7(a)及び(b)は、その他の態様を有する排水案内部107の構造を示す図であって、図7(a)は、その他の排水案内部107を主管部3内部から下方に見た平面図であり、図7(b)は、その他の排水案内部107を主管部3内部の下流側X2から上流側X1に見た正面図である。
3. 3. Other Structure of Drainage Guide The Drainage Guide may have the same mode as the modified examples shown in FIGS. 7 (a) and 7 (b). 7 (a) and 7 (b) are views showing the structure of the drainage guide portion 107 having another aspect, and FIG. 7 (a) shows the other drainage guide portion 107 downward from the inside of the main pipe portion 3. 7 (b) is a front view of the other drainage guide portion 107 as viewed from the downstream side X2 to the upstream side X1 inside the main pipe portion 3.

図7(a)及び(b)に示すとおり、排水案内部107は、これを構成する第一排水遮断部109aと、第二排水遮断部109bと、排水支持部111と、を完全に異なる面で形成したものである。第一排水遮断部109aは、側管部5と主管部3との合流口の上流側X1の端縁近傍で、合流口から主管部3内に突出(方向Y)し、主管部3の方向Xに対して略鉛直かつ方向Zに立ち上がる壁状部位であり、側管部5から主管部3に流入した汚水の流水方向が上流側X1に向かないよう強制するものである。 As shown in FIGS. 7A and 7B, the drainage guide portion 107 completely differs from the first drainage cutoff portion 109a, the second drainage cutoff portion 109b, and the drainage support portion 111 that constitute the drainage guide portion 107. It was formed in. The first drainage cutoff portion 109a protrudes (direction Y) from the confluence into the main pipe portion 3 in the vicinity of the edge of the upstream side X1 of the confluence of the side pipe portion 5 and the main pipe portion 3, and is in the direction of the main pipe portion 3. It is a wall-shaped portion that rises substantially vertically with respect to X and rises in the direction Z, and forces the flow direction of the sewage flowing from the side pipe portion 5 to the main pipe portion 3 so as not to face the upstream side X1.

また、第二排水遮断部109bは、上述した第一排水遮断部109aと、後述する排水支持部111と、の方向Y側の端縁に接続され、側管部5と主管部3との合流口に対向(方向Yに対向)する壁状部位であり、側管部5から流れてきた汚水が方向Yに直進して主管部3内に流入することを妨げるものである。 Further, the second drainage cutoff portion 109b is connected to the end edge on the direction Y side of the first drainage cutoff portion 109a described above and the drainage support portion 111 described later, and joins the side pipe portion 5 and the main pipe portion 3. It is a wall-shaped portion facing the mouth (opposing the direction Y), and prevents the sewage flowing from the side pipe portion 5 from going straight in the direction Y and flowing into the main pipe portion 3.

排水支持部111は、側管部5と主管部3との合流口の下方の端縁近傍で、合流口から主管部3内に突出(方向Y)し、方向Zの下方及び下流側X2に向かって傾斜するよう形成された床状部位である。排水支持部111の上流側X1の端縁は、第一排水遮断部109aの方向Zの下方の端縁と接続され、また排水支持部111の方向Yの端縁は、第二排水遮断部109bの方向Zの下方の端縁と接続されている。 The drainage support portion 111 projects (direction Y) from the confluence into the main pipe portion 3 in the vicinity of the lower edge of the confluence of the side pipe portion 5 and the main pipe portion 3, and extends downward in the direction Z and to the downstream side X2. It is a floor-like part formed so as to incline toward. The edge of the upstream side X1 of the drainage support portion 111 is connected to the lower edge of the first drainage cutoff portion 109a in the direction Z, and the edge of the drainage support portion 111 in the direction Y is connected to the second drainage cutoff portion 109b. It is connected to the lower edge in the direction Z of.

なお、排水案内部107を構成する第一排水遮断部109a、第二排水遮断部109b及び排水支持部111の配設角度は、必ずしも図7(a)及び(b)に順ずる必要なく、状況に応じて適宜変更した態様としてもよいことは言うまでもない。 The arrangement angles of the first drainage cutoff section 109a, the second drainage cutoff section 109b, and the drainage support section 111 constituting the drainage guide section 107 do not necessarily have to follow FIGS. 7 (a) and 7 (b). Needless to say, the mode may be appropriately changed according to the situation.

本実施形態の管継手1は、側管部から主管部に流入する汚水を主管部の下流側に誘導し、排水ヘッダーの排水性を好適に向上するものである。 The pipe joint 1 of the present embodiment guides the sewage flowing from the side pipe portion to the main pipe portion to the downstream side of the main pipe portion, and preferably improves the drainage property of the drainage header.
