Description

本発明は、補修用継手に関するものである。   The present invention relates to a repair joint.

従来、住宅などの建物の床下では、例えば風呂、厨房、トイレ、洗面所などに接続する各種排水管を集合させて設置する排水ヘッダーシステムによる排水設備が知られている。このような排水ヘッダーシステムでは、配管の点検や補修時に狭い配管部分に作業者が潜り込む必要があるが、床下には多数の配管が配置されていて、作業者の移動が困難であることから、一時的に配管の一部を切り離して移動するスペースを確保している。
そして、一時的に切断した箇所に配管を接続して補修するときには、補修用の継手が必要であり、このような補修用継手として、床下配管の補修や排水性能を維持することを目的とした継手が知られている（例えば、特許文献１参照）。 2. Description of the Related Art Conventionally, a drainage facility using a drainage header system in which various drainage pipes connected to, for example, a bath, a kitchen, a toilet, a washroom, and the like are assembled and installed under a floor of a building such as a house is known. In such a drain header system, it is necessary for an operator to sink into a narrow pipe part at the time of inspection and repair of the pipe, but since many pipes are arranged under the floor, it is difficult for the worker to move, A space for temporarily separating and moving part of the piping is secured.
And, when connecting and repairing a pipe to a temporarily cut location, a repair joint is required, and as such a repair joint, the purpose was to maintain repair and drainage performance of underfloor piping A joint is known (see, for example, Patent Document 1).

特許文献１は、床下に配管される排水管の一部を取り外し可能に接続するユニオン式管継手からなり、ユニオンねじが設けられた配管受口と、配管受口に接合されるフランジ付き配管受口と、このフランジ付き配管受口のフランジをユニオンねじ側に締着するユニオンナットと、を備えた構成の脱着継手について記載されている。   Patent Document 1 is composed of a union-type pipe joint that removably connects a part of a drain pipe piped under the floor, and a pipe receptacle provided with a union screw and a pipe receptacle with a flange joined to the pipe receptacle. A detachable joint having a structure including a port and a union nut that fastens the flange of the flanged pipe receiving port to the union screw side is described.

しかしながら、上述した従来の補修用継手では、以下のような問題があった。
すなわち、特許文献１では、補修用の配管を既設配管に対して正確に合わせる必要があり、狭い箇所での位置決めの作業に手間がかかるなど施工性に問題があった。
また、既設配管の切断端部の位置が決まっているので、その既設配管同士の間の寸法に合わせた長さ精度の高い補修用配管を製造する必要がある。しかも、補修用配管の長さが合わないまま補修用継手を使用して連結すると、その接続部分に隙間（溝）や段差が生じ、その凹凸部に流体内の汚物等が滞留し、管路が閉塞するおそれがあった。
したがって、配管補修時の施工性の問題と、接続箇所の閉塞の問題とをバランスよく達成することができる継手構造が求められており、その点で改良の余地があった。 However, the conventional repair joint described above has the following problems.
That is, in patent document 1, it is necessary to match | combine the piping for repair correctly with the existing piping, and there existed a problem in workability, such as taking the work of positioning in a narrow location.
Further, since the position of the cut end of the existing pipe is determined, it is necessary to manufacture a repair pipe with high length accuracy that matches the dimension between the existing pipes. In addition, if the repair pipe is connected without the length of the repair pipe being connected, a gap (groove) or a step is formed in the connecting portion, and dirt or the like in the fluid stays in the uneven portion, and the pipe line Could be blocked.
Therefore, there is a demand for a joint structure that can achieve a good balance between the problem of workability at the time of pipe repair and the problem of blockage of connection points, and there is room for improvement in that respect.

本発明は、上述する問題点に鑑みてなされたもので、配管の着脱作業を容易に行なえる構造とすることで配管補修時の施工効率を向上させることができるうえ、接続部分で流体内の汚物が滞留することを抑制することができる補修用継手を提供することを課題とする。   The present invention has been made in view of the above-described problems, and it is possible to improve the construction efficiency at the time of pipe repair by adopting a structure capable of easily attaching and detaching the pipe. It is an object of the present invention to provide a repair joint capable of suppressing stagnation of filth.

上記目的を達成するため、本発明に係る補修用継手では、既設配管の一部を除去して形成される上流側管路端部と下流側管路端部との間で、上流側管体と下流側管体とを接続する補修用継手であって、上流側管路端部と下流側管路端部との間に装着されると共に、一端側が上流側管体又は下流側管体に対して管軸方向に移動可能に嵌着される継手管と、継手管の内側に挿嵌され、上流側管路端部と下流側管路端部との間に形成される管路の少なくとも下半部において、上流側から下流側に向けて水平又は下向きの流路面を形成するガイドと、が設けられていることを特徴としている。   In order to achieve the above object, in the repair joint according to the present invention, an upstream pipe body is formed between an upstream pipe end and a downstream pipe end formed by removing a part of an existing pipe. And a downstream joint, and is attached between the upstream pipe end and the downstream pipe end, and one end is connected to the upstream pipe or the downstream pipe. A joint pipe that is movably fitted in the pipe axis direction, and at least a pipe line that is inserted inside the joint pipe and formed between the upstream pipe line end part and the downstream pipe line end part. The lower half is provided with a guide that forms a horizontal or downward flow path surface from the upstream side toward the downstream side.

本発明の補修用継手によれば、既設配管の一部を除去して形成される上流側管路端部と下流側管路端部との間に管路を形成する際に、継手管の一端を上流側管体又は下流側管体に対して管軸方向に移動可能に嵌着させ、その継手管の他端を所定の連結位置から嵌着位置側へ移動させておく。そして、継手管の他端側に位置する上流側管路端部又は下流側管路端部と継手管との間に上流側管体又は下流側管体を接続する。このとき、継手管の他端と上流側管体又は下流側管体との間には流路方向の隙間が形成されているので、継手管を下流側又は上流側に移動させることにより、継手管の他端を上流側管体又は下流側管体に連結させることができる。つまり、継手管の他端側に配設される上流側管体又は下流側管体の設置前に、継手管を嵌着位置側へ移動させておくことで、配設する上流側管体又は下流側管体の管軸方向の長さ寸法より大きな距離の空間を形成しておくことができる。そのため、配設する上流側管体又は下流側管体を位置決めして連結する作業を容易に行うことができるうえ、その上流側管体又は下流側管体の長さ精度の高い配管を使用する必要がなくなる。   According to the repair joint of the present invention, when forming a pipe line between the upstream pipe end and the downstream pipe end formed by removing a part of the existing pipe, One end is fitted to the upstream pipe body or the downstream pipe body so as to be movable in the pipe axis direction, and the other end of the joint pipe is moved from a predetermined connection position to the fitting position side. Then, the upstream pipe body or the downstream pipe body is connected between the upstream pipe end or the downstream pipe end located on the other end side of the joint pipe and the joint pipe. At this time, since a gap in the flow path direction is formed between the other end of the joint pipe and the upstream pipe body or the downstream pipe body, the joint pipe is moved to the downstream side or the upstream side, The other end of the tube can be connected to an upstream tube or a downstream tube. In other words, before installing the upstream pipe or the downstream pipe disposed on the other end side of the joint pipe, the joint pipe is moved to the fitting position side, so that the upstream pipe disposed or A space having a distance larger than the length dimension of the downstream pipe body in the tube axis direction can be formed. Therefore, it is possible to easily perform the work of positioning and connecting the upstream pipe body or the downstream pipe body to be arranged, and use a pipe with high length accuracy of the upstream pipe body or the downstream pipe body. There is no need.

また、継手管を上流側管体及び下流側管体に連結した状態で、上流側管路端部と下流側管路端部との間に形成される管路の少なくとも下半部には、継手管内に設けられるガイドによって上流側から下流側に向けて水平又は下向きの流路面が形成されているので、その管路内において流体の流れが規制されずにスムーズな流通となる。そのため、流体内の汚物等が滞留するのを抑えることができ、補修用継手を用いた補修箇所での管路の閉塞を抑制することができる。   Further, in a state where the joint pipe is connected to the upstream side pipe body and the downstream side pipe body, at least the lower half part of the pipe line formed between the upstream side pipe end part and the downstream side pipe end part, Since the horizontal or downward flow path surface is formed from the upstream side toward the downstream side by the guide provided in the joint pipe, the flow of the fluid is not regulated in the pipe line, and the flow is smooth. Therefore, it can suppress that the filth etc. in a fluid retain, and can obstruct | occlude the pipe line in the repair location using the joint for repair.

また、本発明に係る補修用継手では、継手管は、上流側管体又は下流側管体に管軸方向に移動可能に外嵌される摺動管と、一端側が上流側管体又は下流側管体と連結可能とされ、他端側が摺動管に連結される固定管と、を備えていることが好ましい。   In the repair joint according to the present invention, the joint pipe includes a sliding pipe that is externally fitted to the upstream pipe body or the downstream pipe body so as to be movable in the pipe axis direction, and one end side of the joint pipe is the upstream pipe body or the downstream side. It is preferable to include a fixed tube that is connectable to the tube body and has the other end connected to the sliding tube.

この場合には、上流側管体又は下流側管体に嵌着させた継手管を移動させる過程において、摺動管の一端側を上流側管体又は下流側管体に嵌着させて上流側又は下流側に移動させておき、摺動管の他端側と下流側管路端部との間に上流側管体又は下流側管体を配置するとともに、摺動管の他端側を固定管の他端に連結させる。そして、固定管とともに摺動管を上記配置した上流側管体側又は下流側管体側に移動させることにより、固定管の一端を前記配置した上流側管体又は下流側管体に連結することができる。   In this case, in the process of moving the joint pipe fitted to the upstream pipe or the downstream pipe, one end of the sliding pipe is fitted to the upstream pipe or the downstream pipe to Alternatively, it is moved to the downstream side, and the upstream tube or the downstream tube is arranged between the other end of the slide tube and the downstream pipe end, and the other end of the slide tube is fixed. Connect to the other end of the tube. Then, by moving the sliding tube together with the fixed tube to the upstream tube body side or the downstream tube body side arranged above, one end of the fixed tube can be connected to the arranged upstream tube body or the downstream tube body. .

また、本発明に係る補修用継手では、ガイドは、継手管内で継手管に対して管軸方向に相対的に移動可能に設けられるとともに、一端が上流側管体に嵌着可能に設けられ、継手管は、ガイドを上流側管体に嵌着させた状態で、この上流側管体に対して管軸方向に移動可能に嵌着することが好ましい。   Further, in the repair joint according to the present invention, the guide is provided so as to be relatively movable in the pipe axis direction with respect to the joint pipe within the joint pipe, and one end thereof is provided to be fitted to the upstream pipe body, The joint pipe is preferably fitted so as to be movable in the pipe axis direction with respect to the upstream pipe body in a state where the guide is fitted to the upstream pipe body.

この場合、継手管内に設けられるガイドが上流側管体に嵌着されているので、継手管を上流側管体および下流側管体の両方に連結し、上流側管路端部と下流側管路端部との間に連通する管路を形成させた後で、ガイドが継手管とともに移動することを防止することができる。そのため、ガイドによって上流側から下流側に向けて水平又は下向きに形成される前記流路面を維持することができる。   In this case, since the guide provided in the joint pipe is fitted to the upstream pipe, the joint pipe is connected to both the upstream pipe and the downstream pipe, and the upstream pipe end and the downstream pipe are connected. It is possible to prevent the guide from moving together with the joint pipe after the pipe line communicating with the road end portion is formed. Therefore, the flow path surface formed horizontally or downward from the upstream side to the downstream side by the guide can be maintained.

また、本発明に係る補修用継手では、ガイドは、固定管に連結した下流側管体の上流側端部の上方を覆うことが好ましい。   In the repair joint according to the present invention, it is preferable that the guide covers an upper portion of the upstream end portion of the downstream tube connected to the fixed tube.

本発明の補修用継手によれば、継手管と下流側管路との接続部分の下半部において、その接続部分がガイドによって覆われて管路内面に露出しないので、その流路面に上向きの凹凸部が形成されず、流通する流体を汚物等が滞留することなくスムーズに流通させることができる。   According to the repair joint of the present invention, in the lower half of the connection portion between the joint pipe and the downstream pipe line, the connection part is covered with the guide and is not exposed to the inner surface of the pipe line. The uneven portion is not formed, and the circulating fluid can be smoothly circulated without filth and the like remaining.

本発明の補修用継手によれば、配管の着脱作業を容易に行なえる構造とすることで配管補修時の施工効率を向上させることができるうえ、接続部分で流体内の汚物が滞留することを抑制することができる。   According to the repair joint of the present invention, it is possible to improve the construction efficiency at the time of pipe repair by adopting a structure that makes it easy to attach and detach the pipe, and that dirt in the fluid stays at the connection part. Can be suppressed.

The central axes of the upstream pipe 2 and the downstream existing pipe 30 are referred to as pipe axes O1 and O2, respectively, and the direction along the pipe axes O1 and O2 is referred to as the pipe axis direction X, and the pipe axis O1. , The direction orthogonal to O2 is referred to as the radial direction, and the direction around the tube axes O1, O2 is referred to as the circumferential direction. The pipe axis O2 of the repair pipe 3 is slightly shifted downward from the pipe axis O1 of the upstream pipe body 2.

図１に示すように、補修用配管３は、配管補修時に既設配管３０の端部（下流側管路端部３０ａ）に接続ソケット３１を介して連結される。これら図１に示す配管は、上流側から下流側に向けて、上流側管体２、継手管１０、補修用配管３、接続ソケット３１、既設配管３０がこの順でそれぞれの管軸方向Ｘを同一方向に向けた状態で接続される。

Here, the existing pipe 30 is fitted into the fitting part 31b on the downstream side of the connection socket 31, and one end of the repair pipe 3 is fitted into the fitting part 31c on the upstream side. The downstream pipe end 30a of the existing pipe 30 inserted into the connection socket 31 and the downstream end 3a of the repair pipe 3 are brought into contact with the locking ring 31a to determine the position in the pipe axis direction X. Further, the existing pipe 30 and the repair pipe 3 are bonded to the inner surfaces of the fitting portions 31b and 31c by appropriate fixing means, respectively. The protruding height of the locking ring 31 a is the same as the thickness of each of the existing pipe 30 and the repair pipe 3.

The other end side (upstream end 11 c) is provided with a fixed tube 11 connected to the sliding ring 12.

固定管１１は、上述した接続ソケット３１と同様の構成であり、管軸方向Ｘの中央に位置する内面部分には径方向内方に向けて突出する係止リング１１ａが周方向全周にわたって形成されている。管軸方向Ｘで係止リング１１ａを挟んだ両側の部分には、上流端１１ｃに摺動リング１２が挿嵌され、下流端１１ｂには補修用配管３の上流端３ｂが挿嵌される構成となっている。係止リング１１ａの突出高さは、補修用配管３および後述する下流側筒部１４のそれぞれの肉厚と同寸法とされている。
なお、固定管１１に挿嵌される摺動リング１２および補修用配管３は、係止リング１１ａに当接して管軸方向Ｘの位置が決定され、固定管１１の内面に対して接着されている。 The fixed tube 11 has the same configuration as that of the connection socket 31 described above, and a locking ring 11a that protrudes radially inward is formed on the inner surface portion located in the center of the tube axis direction X over the entire circumference. Has been.

図１〜図３に示すように、摺動リング１２は、上流端１２ａが上流側管路端部２ａ（図１）に対して移動可能に嵌着自在に設けられ、下流端１２ｂが固定管１１の上流端１１ｃに連結可能に設けられている。摺動リング１２は、図１に示す上流側管体２に嵌着する上流側筒部１３と、上流側筒部１３よりも小径に形成されて固定管１１に連結される下流側筒部１４と、を備える二段筒状に形成されている。
図１、図４、及び図５に示すように、上流側筒部１３のうち上流側の内周面には、周方向に沿って止水パッキン１５が装着されている。これにより、上流側筒部１３は、上流側管体２の外周面に対して液密な状態で嵌着される。 As shown in FIGS. 1 to 3, the sliding ring 12 is provided such that the upstream end 12 a is movably fitted to the upstream pipe end 2 a (FIG. 1), and the downstream end 12 b is a fixed pipe. 11 is provided to be connectable to the upstream end 11c. The sliding ring 12 includes an upstream cylindrical portion 13 that is fitted to the upstream tubular body 2 shown in FIG. 1, and a downstream cylindrical portion 14 that is formed in a smaller diameter than the upstream cylindrical portion 13 and is connected to the fixed tube 11. And a two-stage cylinder.

Thereby, the upstream cylinder part 13 is fitted in a liquid-tight state on the outer peripheral surface of the upstream tube 2.

下流側筒部１４は補修用配管３の管軸Ｏ２と同軸であり、上流側筒部１３は上流側管体２の管軸Ｏ１と同軸であり、下流側筒部１４は上流側筒部１３に対して同軸ではなく下側にずれている。そのため、摺動リング１２の内面は、略上半側の部分では下流側筒部１４の内面と上流側筒部１３の内面との間に径方向内方側に一段凹んだ段差部１２ｃが形成され、略下半側では上流側筒部１３と下流側筒部１４とが面一（平坦面）となっている。つまり、下流側筒部１４は、少なくともその底部内面が図１に示す補修用配管３の内面と略面一状態で連結される。
また、上流側筒部１３は、図１に示す上流側管体２に対して嵌着した状態で、上流側管体２の外周面との間に所定の隙間Ｓ１（図６参照）を有している。この隙間Ｓ１の径方向の寸法は、後述するガイド２０の上流側連結筒部２１に形成される凹陥部２１ａの厚さ寸法とほぼ一致している。 The downstream cylinder portion 14 is coaxial with the tube axis O2 of the repair pipe 3, the upstream cylinder portion 13 is coaxial with the tube axis O1 of the upstream tube body 2, and the downstream cylinder portion 14 is the upstream cylinder portion 13. Is not coaxial but is shifted downward. Therefore, the inner surface of the sliding ring 12 is formed with a step portion 12c that is recessed by one step radially inwardly between the inner surface of the downstream tube portion 14 and the inner surface of the upstream tube portion 13 in the substantially upper half portion. On the substantially lower half side, the upstream side cylindrical portion 13 and the downstream side cylindrical portion 14 are flush with each other (flat surface). That is, at least the bottom inner surface of the downstream side cylindrical portion 14 is connected to the inner surface of the repair pipe 3 shown in FIG.
Further, the upstream tube portion 13 is fitted to the upstream tube 2 shown in FIG. 1 and has a predetermined gap S1 (see FIG. 6) between the upstream tube portion 13 and the outer peripheral surface of the upstream tube 2. doing. The dimension in the radial direction of the gap S1 is substantially the same as the thickness dimension of the recessed portion 21a formed in the upstream connecting cylinder portion 21 of the guide 20 described later.

このように構成される摺動リング１２は、固定管１１を連結させる前に、上流側管体２に対してその端部（上流側管路端部２ａ）から離間する方向の位置（上流側に向かう方向の位置）において止水パッキン１５の部分で嵌着され、下流端１２ｂを固定管１１に連結した後に補修用配管３側へ向けて移動させることが可能な構成となっている。   The sliding ring 12 configured as described above has a position (upstream side) in a direction away from its end (upstream pipe end 2a) with respect to the upstream pipe 2 before connecting the fixed pipe 11. The position of the water stop packing 15 is fitted at the position of the water stop packing 15, and the downstream end 12 b is connected to the fixed pipe 11 and then moved toward the repair pipe 3.

図１、図４、及び図５に示すように、ガイド２０は、上流側連結筒部２１と、下流側に設けられるガイド部２２とを備え、摺動リング１２の上流側筒部１３の内周側で管軸方向Ｘに沿って摺動可能に設けられている。上流側連結筒部２１は上流側管体２の管軸Ｏ１と同軸に設けられ、ガイド部２２は下流側の既設配管３０の管軸Ｏ２と同軸に設けられている。   As shown in FIGS. 1, 4, and 5, the guide 20 includes an upstream connecting cylinder portion 21 and a guide portion 22 provided on the downstream side, and the inside of the upstream cylinder portion 13 of the sliding ring 12. It is slidable along the tube axis direction X on the circumferential side. The upstream connecting cylinder part 21 is provided coaxially with the pipe axis O1 of the upstream pipe body 2, and the guide part 22 is provided coaxially with the pipe axis O2 of the existing pipe 30 on the downstream side.

図６に示すように、上流側連結筒部２１は、外径寸法が摺動リング１２の上流側筒部１３の内径寸法と略同径をなし、上流側端部の内面側に図１に示す上流側管体２の端部（上流側管路端部２ａ）に嵌着する凹陥部２１ａを有している。ガイド２０は、上流側連結筒部２１の上端部が摺動リング１２の段差部１２ｃに当接した状態で、上流側管体２の外面側において、上流側連結筒部２１の上流端２１ｂと摺動リング１２の止水パッキン１５との間に管軸方向Ｘに延びる前記隙間Ｓ１を形成している。この隙間Ｓ１は、ガイド２０が凹陥部２１ａによって上流側管体２に嵌着した状態での摺動リング１２の摺動範囲Ｌ１となる。   As shown in FIG. 6, the upstream connecting cylinder portion 21 has an outer diameter that is substantially the same as the inner diameter dimension of the upstream cylinder portion 13 of the sliding ring 12. It has the recessed part 21a fitted to the edge part (upstream side pipe edge part 2a) of the upstream side pipe body 2 to show. In the state where the upper end portion of the upstream connecting cylinder portion 21 is in contact with the stepped portion 12 c of the sliding ring 12, the guide 20 is connected to the upstream end 21 b of the upstream connecting cylinder portion 21 on the outer surface side of the upstream tube 2. The clearance S <b> 1 extending in the tube axis direction X is formed between the sliding ring 12 and the water stop packing 15. The gap S1 is a sliding range L1 of the sliding ring 12 in a state where the guide 20 is fitted to the upstream tube 2 by the recessed portion 21a.

図５に示すように、ガイド部２２は、摺動リング１２の下流側筒部１４の内面に沿って上流側連結筒部２１の下流側に連設され、上部が開口し、その上端開口縁部は管軸方向Ｘで上流側連結筒部２１から離れる方向（下流側）に向けて漸次低くなる形状となっている。
ガイド部２２の下流側の部分は、ガイド２０が摺動リング１２に装着された状態で、摺動リング１２の下流端１２ｂから管軸方向Ｘで下流側に向けて所定の張出し長Ｌ２をもって突出している。このガイド部２２の張出し長Ｌ２は、図６に示すように、摺動リング１２に固定管１１を嵌着させた状態で、少なくとも固定管１１の係止リング１１ａよりもさらに下流側に向けて突出している。 As shown in FIG. 5, the guide portion 22 is connected to the downstream side of the upstream connecting tube portion 21 along the inner surface of the downstream tube portion 14 of the sliding ring 12, and the upper portion is open, and the upper end opening edge thereof The portion has a shape that gradually decreases in the tube axis direction X in the direction away from the upstream connecting cylinder portion 21 (downstream side).
The downstream portion of the guide portion 22 protrudes from the downstream end 12b of the sliding ring 12 toward the downstream side in the tube axis direction X with a predetermined overhang length L2 in a state where the guide 20 is mounted on the sliding ring 12. ing. As shown in FIG. 6, the overhang length L <b> 2 of the guide portion 22 is at least further downstream than the locking ring 11 a of the fixed tube 11 in a state where the fixed tube 11 is fitted to the sliding ring 12. It protrudes.

図６においてガイド部２２の下流側先端２２ａは、固定管１１の下流端１１ｂ付近に至る位置まで延在している。このときの突出するガイド部２２と固定管１１の内面１１ｄとの間には隙間Ｓ２が形成され、この隙間Ｓ２の部分に補修用配管３の上流端３ｂが嵌入される。つまり、ガイド部２２は、固定管１１に挿嵌された補修用配管３の上流端３ｂ側の下側部分の上に、その下側部分を覆うようにして配置されている。   In FIG. 6, the downstream end 22 a of the guide portion 22 extends to a position reaching the vicinity of the downstream end 11 b of the fixed tube 11. A gap S2 is formed between the protruding guide portion 22 and the inner surface 11d of the fixed pipe 11 at this time, and the upstream end 3b of the repair pipe 3 is inserted into the gap S2. That is, the guide part 22 is disposed on the lower part of the repair pipe 3 inserted into the fixed pipe 11 so as to cover the lower part thereof.

以上説明した本実施形態による補修用継手によれば、以下の施工手順によって補修され、以下の作用効果を奏する。
すなわち、図１に示すように、本実施の形態の補修用継手１では、既設配管の一部を除去して形成される上流側管路端部２ａと下流側管路端部３０ａとの間に管路を形成する際に、先ず継手管１０の止水パッキン１５を装着させた摺動リング１２とガイド２０を組み合わせる（図２〜図５参照）。すなわち、摺動リング１２の上流端１２ａの開口から、ガイド２０を挿嵌させる。 According to the joint for repair by this embodiment demonstrated above, it repairs by the following construction procedures, and there exist the following effects.
That is, as shown in FIG. 1, in the repair joint 1 of the present embodiment, between the upstream side pipe end 2 a and the downstream side pipe end 30 a formed by removing a part of the existing pipe. When the pipe is formed, the sliding ring 12 to which the water stop packing 15 of the joint pipe 10 is attached is first combined with the guide 20 (see FIGS. 2 to 5). That is, the guide 20 is inserted from the opening of the upstream end 12 a of the sliding ring 12.

次に、図６に示すように、継手管１０の上流端１２ａを上流側管体２に対して管軸方向Ｘに移動可能に嵌着させ、その摺動リング１２の下流端１２ｂを所定の連結位置から嵌着位置側（上流側）へ移動させておく。具体的には、ガイド２０の凹陥部２１ａを、摺動リング１２を備えたまま上流側管体２に嵌合させ、これら凹陥部２１ａと上流側管体２とを適宜な固着手段により接着する。このとき、摺動リング１２は、段差部１２ｃを上流側連結筒部２１の下流側上端２１ｃに当接させた状態において、摺動リング１２の上流側筒部１３は止水パッキン１５が上流側管体２の外周面に液密に接触し、上流側管体２の外周側に一定の隙間Ｓ１をあけて配置される。
次いで、上流側管体２に嵌着させた摺動リング１２の下流側筒部１４に固定管１１の上流端１１ｃを連結させる。 Next, as shown in FIG. 6, the upstream end 12 a of the joint pipe 10 is fitted to the upstream side pipe body 2 so as to be movable in the pipe axis direction X, and the downstream end 12 b of the sliding ring 12 is set to a predetermined level. It is moved from the coupling position to the fitting position side (upstream side). Specifically, the recessed portion 21a of the guide 20 is fitted to the upstream side tubular body 2 with the sliding ring 12 provided, and the recessed portion 21a and the upstream side tubular body 2 are bonded by an appropriate fixing means. . At this time, in the sliding ring 12, in the state where the stepped portion 12 c is in contact with the downstream upper end 21 c of the upstream connecting cylindrical portion 21, the upstream cylindrical portion 13 of the sliding ring 12 has the water stop packing 15 on the upstream side. The pipe body 2 is in liquid-tight contact with the outer peripheral surface of the pipe body 2 and is arranged with a certain gap S1 on the outer peripheral side of the upstream pipe body 2.
Next, the upstream end 11 c of the fixed tube 11 is connected to the downstream cylindrical portion 14 of the sliding ring 12 fitted to the upstream tube 2.

そして、図１に示すように、継手管１０と下流側管路端部３０ａとの間において、下流側の既設配管３０に対して接続ソケット３１を介して補修用配管３を接続する。このとき、固定管１１の下流端１１ｂと補修用配管３との間には流路方向の隙間が形成されているので、図７に示すように、継手管１０を下流側に向けて移動させることにより、固定管１１の下流端１１ｂを補修用配管３に連結させることができる。この場合、図６に示すように、ガイド部２２と固定管１１の下流側内面との間に形成される隙間Ｓ２に、補修用配管３の底部分３ｃが嵌め込まれ、補修用配管３の底部分３ｃの内面がガイド部２２の内面（流路面２０ａ）よりも低い位置（半径方向で外方の位置）となる。   Then, as shown in FIG. 1, the repair pipe 3 is connected to the existing pipe 30 on the downstream side via the connection socket 31 between the joint pipe 10 and the downstream pipe end 30 a. At this time, since a gap in the flow path direction is formed between the downstream end 11b of the fixed pipe 11 and the repair pipe 3, the joint pipe 10 is moved toward the downstream side as shown in FIG. Thus, the downstream end 11 b of the fixed pipe 11 can be connected to the repair pipe 3. In this case, as shown in FIG. 6, the bottom portion 3 c of the repair pipe 3 is fitted into a gap S <b> 2 formed between the guide portion 22 and the downstream inner surface of the fixed pipe 11, and the bottom of the repair pipe 3 The inner surface of the portion 3c is at a lower position (the outer position in the radial direction) than the inner surface (flow channel surface 20a) of the guide portion 22.

このように、補修用配管３の設置前に継手管１０を嵌着位置側へ移動させておくことで、配設する補修用配管３の管軸方向Ｘの長さ寸法より大きな距離の空間を形成しておくことができる。そのため、配設する補修用配管３を位置決めして連結する作業を容易に行うことができるうえ、その補修用配管３の長さ精度の高い配管を使用する必要がなくなる。   Thus, by moving the joint pipe 10 to the fitting position side before installing the repair pipe 3, a space having a distance larger than the length dimension in the pipe axial direction X of the repair pipe 3 to be arranged is provided. Can be formed. Therefore, it is possible to easily perform the operation of positioning and connecting the repairing pipe 3 to be disposed, and it is not necessary to use a pipe with high length accuracy of the repairing pipe 3.

また、継手管１０を補修用配管３に連結した状態で、上流側管路端部２ａと下流側管路端部３０ａ（図１参照）との間に形成される管路の少なくとも下半部には、継手管１０内に設けられるガイド２０によって上流側から下流側に向けて水平又は下向きの流路面が形成されているので、その管路内において流体の流れが規制されずにスムーズな流通となる。そのため、流体内の汚物等が滞留するのを抑えることができ、補修用継手１を用いた補修箇所での管路の閉塞を抑制することができる。   Further, at least the lower half part of the pipe formed between the upstream pipe end 2a and the downstream pipe end 30a (see FIG. 1) in a state where the joint pipe 10 is connected to the repair pipe 3. In this case, a horizontal or downward flow path surface is formed from the upstream side toward the downstream side by the guide 20 provided in the joint pipe 10, so that the flow of fluid is not restricted in the pipe line and is smoothly distributed. It becomes. Therefore, it can suppress that the filth etc. in a fluid retain, and can obstruct | occlude the obstruction | occlusion of the pipe line in the repair location using the joint 1 for repair.

また、上流側管体２に外嵌させた継手管１０（摺動リング１２）を移動させる過程において、摺動リング１２の一端側を上流側管体２に嵌着させて上流側に移動させておき、継手管１０の下流端１１ｂと下流側管路端部３０ａとの間に補修用配管３を配置するとともに、摺動リング１２の下流端１２ｂを固定管１１の他端に連結させる。そして、固定管１１とともに摺動リング１２を補修用配管３側に移動させることにより、固定管１１の下流端１１ｂを補修用配管３に連結することができる。   Further, in the process of moving the joint pipe 10 (sliding ring 12) externally fitted to the upstream side pipe body 2, one end side of the sliding ring 12 is fitted to the upstream side pipe body 2 and moved to the upstream side. The repair pipe 3 is disposed between the downstream end 11 b of the joint pipe 10 and the downstream pipe end 30 a, and the downstream end 12 b of the sliding ring 12 is connected to the other end of the fixed pipe 11. And the downstream end 11b of the fixed pipe 11 can be connected to the repair pipe 3 by moving the sliding ring 12 together with the fixed pipe 11 to the repair pipe 3 side.

また、継手管１０内に挿嵌されるガイド２０が上流側管体２に嵌着されているので、継手管１０を上流側管体２と補修用配管３に連結し、上流側管路端部２ａと下流側管路端部３０ａとの間に連通する管路を形成させた後で、ガイド２０が継手管１０とともに移動することを防止することができる。そのため、ガイド２０によって上流側から下流側に向けて水平又は下向きに形成される流路面を維持することができる。   Further, since the guide 20 inserted into the joint pipe 10 is fitted to the upstream pipe 2, the joint pipe 10 is connected to the upstream pipe 2 and the repair pipe 3, and the upstream pipe end is connected. It is possible to prevent the guide 20 from moving together with the joint pipe 10 after forming a pipe line communicating between the portion 2a and the downstream pipe end part 30a. Therefore, the flow path surface formed horizontally or downwardly from the upstream side toward the downstream side by the guide 20 can be maintained.

さらに、継手管１０と補修用配管３との接続部分の下半部において、その接続部分がガイド２０のガイド部２２によって覆われて管路内面に露出しないので、その流路面に上向きの凹凸部が形成されず、流通する流体を汚物等が滞留することなくスムーズに流通させることができる。   Further, in the lower half portion of the connection portion between the joint pipe 10 and the repair pipe 3, the connection portion is covered by the guide portion 22 of the guide 20 and is not exposed to the inner surface of the pipe line. Is formed, and the circulating fluid can be smoothly circulated without stagnation of filth and the like.

上述のように本実施の形態による補修用継手では、配管の着脱作業を容易に行なえる構造とすることで配管補修時の施工効率を向上させることができるうえ、接続部分で流体内の汚物が滞留することを抑制することができる。   As described above, in the repair joint according to the present embodiment, it is possible to improve the construction efficiency at the time of pipe repair by adopting a structure that allows easy attachment / detachment of the pipe, and dirt in the fluid at the connection portion. It can suppress staying.

以上、本発明による補修用継手の実施の形態について説明したが、本発明は上記の実施の形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。
例えば、上述の本実施の形態における継手管１０では摺動リング１２に固定管１１を備えているが、固定管１１を省略した構成、すなわち摺動リング１２とガイド２０のみからなる補修用継手としてもよい。 As mentioned above, although embodiment of the joint for repair by this invention was described, this invention is not limited to said embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, in the joint pipe 10 in the above-described embodiment, the sliding ring 12 includes the fixed pipe 11, but the structure in which the fixed pipe 11 is omitted, that is, a repair joint including only the sliding ring 12 and the guide 20. Also good.

また、本実施の形態では摺動リング１２の上流側筒部１３側からガイド２０を挿嵌させて組み付けることが可能な構成としているが、このような構造であることに限定されることはない。例えば、図８に示すように、上流側筒部１３の上流側の止水パッキン１５の装着箇所で本体筒部１３Ａと上流端筒部１３Ｂとに管軸方向Ｘに分離された構成としてもよい。この場合、上流端筒部１３Ｂの上流側端部１３ｂの径方向内方の位置が、ガイド２０の凹陥部２１ａの内面の位置に一致しており、摺動リング１２内に組み込まれたガイド２０が上流端筒部１３Ｂの開口から突出しないように移動が規制された構成となっている。   Further, in the present embodiment, the guide 20 can be inserted and assembled from the upstream cylindrical portion 13 side of the sliding ring 12, but it is not limited to such a structure. . For example, as shown in FIG. 8, it is good also as a structure isolate | separated into the main body cylinder part 13A and the upstream end cylinder part 13B in the pipe-axis direction X in the attachment location of the upstream water stop packing 15 of the upstream cylinder part 13. . In this case, the radially inner position of the upstream end portion 13b of the upstream end cylindrical portion 13B coincides with the position of the inner surface of the recessed portion 21a of the guide 20, and the guide 20 incorporated in the sliding ring 12. However, the movement is restricted so as not to protrude from the opening of the upstream end cylinder portion 13B.

さらに、本実施の形態では継手管１０の摺動リング１２を上流側管体２に対して移動可能に嵌着させているが、これに限らず、その摺動リング１２を下流側の既設配管３０に嵌着させることも可能である。この場合、摺動リング１２よりも上流側に位置する固定管１１が上流側管体２（或いは、上流側管体２に連結される補修用配管）に連結される構成となるが、さらにガイド２０のガイド部２２は上述した実施の形態と同様に上流側から下流側に向けて水平又は下向きの流路面を形成する構成となる。   Further, in the present embodiment, the sliding ring 12 of the joint pipe 10 is movably fitted to the upstream side pipe body 2. However, the present invention is not limited to this, and the sliding ring 12 is connected to the existing piping on the downstream side. 30 can be fitted. In this case, the fixed pipe 11 positioned on the upstream side of the sliding ring 12 is connected to the upstream pipe body 2 (or a repair pipe connected to the upstream pipe body 2), but the guide is further guided. The 20 guide portions 22 are configured to form a horizontal or downward flow path surface from the upstream side toward the downstream side as in the above-described embodiment.

さらにまた、本実施の形態では上流側管体２に対して移動可能に嵌着させた摺動リング１２の下流端１２ｂに固定管１１を連結させてから、継手管１０を補修用配管３側に向けて移動させる手順としているが、このような施工手順に制限されることはない。例えば固定管１１を補修用配管３に先に連結させておき、摺動リング１２を固定管１１側に移動させ、摺動リング１２の下流端１２ｂを固定管１１の上流端１１ｃに挿嵌させる手順による施工方法とすることも可能である。   Furthermore, in the present embodiment, the fixed pipe 11 is connected to the downstream end 12b of the sliding ring 12 movably fitted to the upstream pipe body 2, and then the joint pipe 10 is connected to the repair pipe 3 side. However, it is not limited to such a construction procedure. For example, the fixed tube 11 is first connected to the repair pipe 3, the sliding ring 12 is moved to the fixed tube 11 side, and the downstream end 12 b of the sliding ring 12 is inserted into the upstream end 11 c of the fixed tube 11. It is also possible to adopt a construction method according to the procedure.

また、ガイド２０の形状、ガイド部２２の管軸方向の長さ寸法などの構成についても、本実施の形態に限定されることはない。例えば、上方が開口した形状となっているが、筒状になっていてもよい。さらに他の例として、ガイド２０の上流側連結筒部２１が上下方向に二分割され、そのうち下半分のみとした形状のガイド、すなわち管軸方向全体にわたってガイドの上部が開放された構成であってもかまわない。この場合、上流側管体２の下半部分のみに上流側連結筒部２１を接着により連結することで、上流側から下流側に向けて水平又は下向きに形成される流路面を確保することができ、ガイドとしての機能をもたせることができる。
さらにまた、本実施の形態ではガイド部２２の下流側先端２２ａが摺動リング１２に連結した固定管１１の下流端１１ｂよりも下流側に突出しない寸法に設定されているが、固定管１１の下流端１１ｂよりもさらに突出する形状とすることも可能である。 Further, the configuration of the shape of the guide 20 and the length dimension of the guide portion 22 in the tube axis direction are not limited to the present embodiment. For example, the shape is open at the top, but may be cylindrical. As yet another example, the upstream connecting cylinder portion 21 of the guide 20 is divided into two in the vertical direction, and only the lower half of the guide 20 is formed, that is, the upper portion of the guide is opened over the entire tube axis direction. It doesn't matter. In this case, it is possible to secure a flow path surface that is formed horizontally or downwardly from the upstream side toward the downstream side by connecting the upstream side connection cylinder portion 21 to only the lower half portion of the upstream side pipe body 2 by bonding. Can be provided as a guide.
Furthermore, in the present embodiment, the downstream end 22a of the guide portion 22 is set to a dimension that does not protrude further downstream than the downstream end 11b of the fixed tube 11 connected to the sliding ring 12. It is also possible to have a shape that protrudes further than the downstream end 11b.

その他、本発明の趣旨を逸脱しない範囲で、上記した実施の形態における構成要素を周知の構成要素に置き換えることは適宜可能である。   In addition, it is possible to appropriately replace the components in the above-described embodiments with known components without departing from the spirit of the present invention.
