Description

本発明は、管底に逆段差が生じにくく排水の流れが阻害されにくい補修継手に関する。 The present invention relates to a repair joint in which a reverse step is unlikely to occur at the tube bottom and the flow of drainage is not easily inhibited.

従来、破損した陶管、ヒューム管およびコンクリート管等（以下、「陶管等」という。）の排水管路を補修する場合には、同種材料の管に交換する作業が行われていた。 Conventionally, when repairing drainage pipes of damaged ceramic pipes, fume pipes, concrete pipes, etc. (hereinafter referred to as “ceramic pipes”), replacement work with pipes of the same kind has been performed.

ここで、近年、排水管路を施工する際に、陶管等よりも軽量で施工性に優れた塩化ビニル等の合成樹脂管が広く使われるようになってきたことから、陶管等は、需要が減少して生産も少なくなってきた。 Here, in recent years, when constructing drainage pipes, synthetic resin pipes such as vinyl chloride, which are lighter than ceramic pipes and have excellent workability, have come to be widely used. Demand has decreased and production has decreased.

このような事情から、既設の陶管等の補修に際しては、陶管等そのものの入手が困難であること、および、施工性の観点から、合成樹脂製の管継手に置き換えて補修が行われるケースが多くなっている。 For these reasons, when repairing existing ceramic pipes, etc., it is difficult to obtain the ceramic pipes themselves, and from the viewpoint of workability, they are replaced with synthetic resin pipe joints. Is increasing.

しかしながら、陶管と塩化ビニル管とのように、管種が異なると規格寸法も異なるため、呼び径が同一であっても異種管をそのまま接続すると、管内の接続部分に段差が生じてしまう。特に、管内で下流側の管底が上流側の管底より突出した逆段差が生じてしまうと、この逆段差により排水の流れを阻害してしまうことがある。 However, since different standard pipes, such as porcelain pipes and vinyl chloride pipes, have different standard dimensions, even if the nominal diameters are the same, connecting different types of pipes as they are will cause a step in the connecting portion of the pipe. In particular, if a reverse step is produced in which the downstream tube bottom protrudes from the upstream tube bottom in the tube, this reverse step may obstruct the flow of drainage.

そこで、陶管等と合成樹脂管とを接続する場合であっても、接続部に逆段差が生じて排水の流れを阻害しないように、接続部の管底を合わせるための技術が知られている。 Therefore, even when connecting ceramic pipes and synthetic resin pipes, there is a known technique for aligning the pipe bottom of the connection part so that a reverse step occurs in the connection part and does not hinder the flow of drainage. Yes.

具体的には、陶管等と合成樹脂管の管底を合わせるために、陶管等の差口を嵌め込む合成樹脂製の受口の内側に位置決め突起が設けられたものがある（例えば、特許文献１参照。）。 Specifically, in order to match the bottoms of the ceramic tube and the synthetic resin tube, there is one in which a positioning projection is provided on the inner side of the synthetic resin receiving port into which the opening of the ceramic tube or the like is fitted (for example, (See Patent Document 1).

しかしながら、陶管等は合成樹脂管に比べて寸法公差が大きいため、特許文献１の構成では、陶管等の寸法誤差次第で接続部に無視できないほどの逆段差が生じてしまう可能性が考えられる。 However, since the dimensional tolerance of ceramic pipes and the like is larger than that of synthetic resin pipes, in the configuration of Patent Document 1, there is a possibility that a reverse step that cannot be ignored is caused in the connection portion depending on the dimensional error of the ceramic pipes. It is done.

そこで、陶管等と合成樹脂管との内側端部同士を当接させ、合成樹脂管の内周面から陶管等の内周面にわたって板片を配置することにより、管底を合わせる方法が知られている（例えば、特許文献２参照。）。 Therefore, there is a method in which the inner ends of the ceramic pipe and the synthetic resin pipe are brought into contact with each other, and a plate piece is arranged from the inner peripheral surface of the synthetic resin pipe to the inner peripheral surface of the ceramic pipe, etc. It is known (for example, refer to Patent Document 2).

特開２００４−２３９２９９号公報（第３，４頁、図１）JP 2004-239299 A (3rd and 4th pages, FIG. 1) 特開２００８−１５０８４５号公報（第３，４頁、図１）JP 2008-150845 A (pages 3 and 4, FIG. 1)

上述の特許文献２の方法によれば、陶管等と合成樹脂管との管底を合わせることが可能であるが、板片そのものが管内で突出することになるので、板片そのものが排水の流れを阻害する原因になってしまう。また、例えば、生分解製樹脂で板片を形成したとしても、完全に分解されるまでに時間がかかるため、その期間は板片が排水の流れを阻害してしまう。 According to the method of Patent Document 2 described above, it is possible to match the bottoms of the ceramic tube and the synthetic resin tube, but the plate piece itself protrudes in the tube, so that the plate piece itself is drained. It becomes the cause which obstructs the flow. For example, even if the plate piece is formed of biodegradable resin, it takes time until the plate piece is completely decomposed, and the plate piece inhibits the flow of drainage during that period.

本発明はこのような点に鑑みなされたもので、管底に逆段差が生じにくく排水の流れが阻害されにくい補修継手を提供することを目的とする。 This invention is made | formed in view of such a point, and it aims at providing the repair joint which a reverse level | step difference does not produce easily on a pipe bottom and the flow of drainage is hard to be inhibited.

The upstream connection member 7 as the other side connection member connected in a watertight manner, and the downstream connection member 6 and the spear member 8 connected in a watertight manner to the upstream connection member 7.

下流側接続部材６は、外径が下流側管路２の受口３の内径より小径で、かつ、内径がヤリトリ部材８の一端の外径より大径の略円筒状であり、一端が下流側管路２の受口３に内挿され、他端がヤリトリ部材８の一端に外挿されて接続される。 The downstream connection member 6 has a substantially cylindrical shape whose outer diameter is smaller than the inner diameter of the receiving port 3 of the downstream pipe line 2 and whose inner diameter is larger than the outer diameter of one end of the spear member 8, and one end is downstream. The other end of the side pipe 2 is inserted into the receiving port 3, and the other end is inserted into one end of the spear member 8 and connected thereto.

図２に示すように、下流側接続部材６は、一端の外周にパッキン取付部10が一体に成形されている。このパッキン取付部10の内側には、周方向に沿って間欠的に配置された間隙11が設けられている。また、下流側接続部材６の一端であるパッキン取付部10の外周面には、偏肉パッキン12が嵌合されている。さらに、下流側接続部材６の一端には、内周面から内側へ突出し、ヤリトリ部材８の一端を係止可能な係止部13が設けられている。 As shown in FIG. 2, the downstream connection member 6 has a packing mounting portion 10 integrally formed on the outer periphery of one end.

図３に示すように、偏肉パッキン12は、パッキン取付部10の外周に嵌合可能な環状に成形され、周方向に沿って厚みが変化している。すなわち、偏肉パッキン12は、周方向の一方側に位置し最も厚みが厚い厚肉部12aと、周方向で厚肉部12aに対向する他方側に位置し最も厚みが薄い薄肉部12bとを有し、厚肉部12aから薄肉部12bに向かって漸次厚みが薄くなっている。また、偏肉パッキン12は、一端側の先端側が他端側より小径に成形され、下流側接続部材６に嵌合された状態にて、下流側管路２の受口３に挿入しやすく成形されている。 As shown in FIG. 3, the uneven thickness packing 12 is formed in an annular shape that can be fitted to the outer periphery of the packing mounting portion 10, and the thickness changes along the circumferential direction. That is, the uneven thickness packing 12 includes a thick part 12a having the thickest thickness located on one side in the circumferential direction and a thin part 12b having the thinnest thickness located on the other side facing the thick part 12a in the circumferential direction.

Then, since the uneven thickness packing 12 and the fixed packing 3a are in contact with each other, the downstream side connection member 6 is connected to the downstream side pipe line 2 in a watertight manner.

上流側接続部材７は、略円筒状であり、一端がヤリトリ部材８の他端に内挿され、他端が上流側管路４に外挿される。 The upstream connection member 7 has a substantially cylindrical shape, one end is inserted into the other end of the spear member 8, and the other end is inserted into the upstream pipe 4.

Further, the tip on one end side of the slide tube portion 14 is formed to have a smaller diameter than the other end side, and is formed so as to be easily fitted to the other end of the spear member 8. Then, with the slide tube portion 14 fitted to the other end of the spear member 8, the slide tube portion 14 is slid with respect to the spear member 8, thereby superimposing the spear member 8 and the slide tube portion 14. The length of the entire repair joint 1 between the downstream pipe line 2 and the upstream pipe line 4 is adjusted by changing the amount.

接続管部15は、一端側に位置し内径が上流側管路４の差口５の外径より大径の第１管部16と、他端側に位置し第１管部16より大径の第２管部17とを有する。さらに、第２管部17の内周面には、第１管部16と第２管部17との境界部分の段差状の箇所に係止されるように、偏肉パッキン18が嵌合されている。 The connecting pipe portion 15 is located on one end side and has an inner diameter that is larger than the outer diameter of the differential port 5 of the upstream side pipe 4 and a larger diameter than the first pipe portion 16 that is located on the other end side.

偏肉パッキン18は、第２管部17の内面に嵌合可能な環状に成形され、図３に示す偏肉パッキン12と同様に周方向に沿って厚みが変化している。すなわち、偏肉パッキン18は、最も厚みが厚い厚肉部18aと最も厚みが薄い薄肉部18bとを有し、この厚肉部18aから薄肉部18bに向かって漸次厚みが薄くなっている。また、偏肉パッキン18は、他端側の先端側が一端側より小径に成形され、上流側接続部材７に嵌合された状態にて、上流側管路４の差口５に挿入しやすく成形されている。 The uneven thickness packing 18 is formed in an annular shape that can be fitted to the inner surface of the second pipe portion 17, and the thickness changes along the circumferential direction as in the case of the uneven thickness packing 12 shown in FIG. 3. That is, the uneven packing 18 has the thickest part 18a having the thickest thickness and the thinned part 18b having the thinnest thickness, and the thickness gradually decreases from the thickest part 18a toward the thinned part 18b. In addition, the uneven thickness packing 18 is formed so that the distal end side of the other end side is formed with a smaller diameter than the one end side and is easily inserted into the outlet 5 of the upstream pipe line 4 while being fitted to the upstream connection member 7.

なお、上流側管路４の差口５の外周には、固定パッキン5aが嵌合されており、上流側接続部材７の他端が上流側管路４の差口５に外挿された状態では、偏肉パッキン18と固定パッキン5aとが接触するため、上流側接続部材７が上流側管路４に水密に接続される。 In addition, the fixed packing 5a is fitted to the outer periphery of the outlet 5 of the upstream pipe 4, and the other end of the upstream connecting member 7 is extrapolated to the outlet 5 of the upstream pipe 4. Then, since the uneven thickness packing 18 and the fixed packing 5a are in contact with each other, the upstream connection member 7 is connected to the upstream pipeline 4 in a watertight manner.

ヤリトリ部材８は、一端の外径が下流側接続部材６の他端の内径より小径で、かつ、他端の内径が上流側接続部材７の一端であるスライド管部14の外径より大径の略円筒状であり、一端が下流側接続部材６の他端に内挿され、他端がスライド管部14に外挿される。 The spear member 8 has an outer diameter at one end smaller than the inner diameter at the other end of the downstream connection member 6 and an inner diameter at the other end larger than the outer diameter of the slide tube portion 14 that is one end of the upstream connection member 7.

この固定手段23は、ヤリトリ部材８とスライド管部14との重ね合わせ量に基づいて、補修継手１全体の長さが調整された状態にて、ヤリトリ部材８とスライド管部14とを固定するものである。 The fixing means 23 fixes the spear member 8 and the slide tube portion 14 in a state where the entire length of the repair joint 1 is adjusted based on the overlapping amount of the spear member 8 and the slide tube portion 14. Is.

次に、上記第１の実施の形態の作用を図５および図６を参照しながら説明する。 Next, the operation of the first embodiment will be described with reference to FIGS.

補修継手１にて例えば陶管等の排水管路を補修するために、下流側管路２と上流側管路４との間に補修継手１を設置する際には、まず、下流側管路２の受口３に下流側接続部材６を挿入して水密に接続する。 When the repair joint 1 is installed between the downstream side pipe 2 and the upstream side pipe 4 in order to repair the drainage pipe such as a ceramic pipe in the repair joint 1, first, the downstream side pipe The downstream connection member 6 is inserted into the second receiving port 3 to make a watertight connection.

また、ヤリトリ部材８に対してスライド管部14を摺動させ、ヤリトリ部材８とスライド管部14との重ね合わせ量を変化させて、下流側管路２と上流側管路４との間における補修継手１全体の長さを適した長さに調整するとともに、上流側管路４の差口５に上流側接続部材７を挿入して水密に接続する。 Further, the slide tube portion 14 is slid with respect to the spear member 8 to change the overlapping amount of the spear member 8 and the slide tube portion 14, so that the space between the downstream pipe line 2 and the upstream pipe line 4 is changed. The entire length of the repair joint 1 is adjusted to an appropriate length, and the upstream connection member 7 is inserted into the outlet 5 of the upstream pipe line 4 to be connected in a watertight manner.

さらに、固定手段23にてヤリトリ部材８とスライド管部14とを固定し、ヤリトリ部材８に対して上流側接続部材７を固定し、下流側管路２と上流側管路４との間における適した長さで補修継手１が設置される。 Furthermore, the spear member 8 and the slide tube portion 14 are fixed by the fixing means 23, the upstream connecting member 7 is fixed to the spear member 8, and between the downstream side pipe 2 and the upstream side pipe 4. The repair joint 1 is installed with a suitable length.

下流側管路２に下流側接続部材６を接続する際には、下流側接続部材６の一端を下流側管路２の受口３に内挿する。 When connecting the downstream connection member 6 to the downstream pipeline 2, one end of the downstream connection member 6 is inserted into the receiving port 3 of the downstream pipeline 2.

ここで、補修継手１と陶管等にて形成された排水管路とは管種が異なるため、図５（ａ）に示すように、下流側管路２の管底と補修継手１の管底との境界部分に逆段差が生じてしまう場合が多い。 Here, since the pipe type is different between the repair joint 1 and the drain pipe formed by the ceramic pipe, the pipe bottom of the downstream pipe 2 and the pipe of the repair joint 1 are shown in FIG. In many cases, a reverse step occurs at the boundary with the bottom.

逆段差が生じた場合には、下流側接続部材６を下流側管路２に対して回動させる。下流側接続部材６を回動させると、下流側接続部材６とともに偏肉パッキン12が下流側管路２に対して回動する。下流側接続部材６とともに偏肉パッキン12が回動することにより、管底側の偏肉パッキン12の厚みの変化にともなって下流側管路２に対する下流側接続部材６の管底の高さが変化し、図５（ｂ）に示すように、下流側管路２の管底と補修継手１の管底との境界部分にほとんど段差が生じていない略平坦な状態に調整できる。 When the reverse step is generated, the downstream connection member 6 is rotated with respect to the downstream pipe 2. When the downstream connection member 6 is rotated, the uneven packing 12 is rotated with respect to the downstream pipe 2 together with the downstream connection member 6. By rotating the uneven thickness packing 12 together with the downstream connection member 6, the height of the tube bottom of the downstream connection member 6 with respect to the downstream side pipe line 2 is increased with the change in the thickness of the uneven thickness packing 12 on the tube bottom side. As shown in FIG. 5 (b), it can be adjusted to a substantially flat state in which almost no step is generated at the boundary between the tube bottom of the downstream side pipe 2 and the tube bottom of the repair joint 1.

上流側管路４に上流側接続部材７を接続する際には、上流側管路４の差口５に上流側接続部材７の他端を外挿する。 When the upstream connecting member 7 is connected to the upstream pipeline 4, the other end of the upstream connecting member 7 is extrapolated to the outlet 5 of the upstream pipeline 4.

上流側管路４と上流側接続部材７との接続においても、下流側管路２と下流側接続部材６との接続の場合と同様に、補修継手１と排水管路との管種が異なるため、図６（ａ）に示すように、上流側管路４の管底と補修継手１の管底との境界部分に逆段差が生じてしまう場合が多い。 In the connection between the upstream pipeline 4 and the upstream connection member 7, as in the case of the connection between the downstream pipeline 2 and the downstream connection member 6, the pipe types of the repair joint 1 and the drain pipeline are different. Therefore, as shown in FIG. 6A, there are many cases where a reverse step occurs at the boundary portion between the pipe bottom of the upstream pipe 4 and the pipe bottom of the repair joint 1.

逆段差が生じた場合には、上流側接続部材７を上流側管路４に対して回動させる。上流側接続部材７を回動させると、上流側接続部材７とともに偏肉パッキン18が上流側管路４に対して回動する。上流側接続部材７とともに偏肉パッキン18が回動することにより、管底側の偏肉パッキン18の厚みの変化にともなって上流側管路４に対する上流側接続部材７の管底の高さが変化し、図６（ｂ）に示すように、上流側管路４の管底と補修継手１の管底との境界部分にほとんど段差が生じていない略平坦な状態に調整できる。 When the reverse step is generated, the upstream connecting member 7 is rotated with respect to the upstream pipeline 4. When the upstream connection member 7 is rotated, the uneven packing 18 is rotated with respect to the upstream pipe 4 together with the upstream connection member 7. By rotating the uneven thickness packing 18 together with the upstream connection member 7, the height of the tube bottom of the upstream connection member 7 with respect to the upstream pipeline 4 is changed as the thickness of the uneven thickness packing 18 on the tube bottom side changes. 6B, it can be adjusted to a substantially flat state in which almost no step is generated at the boundary portion between the pipe bottom of the upstream side pipe 4 and the pipe bottom of the repair joint 1. As shown in FIG.

このように、補修継手１によれば、下流側接続部材６の一端が偏肉パッキン12を介して下流側管路２の受口３に内挿されているので、下流側管路２に対して下流側接続部材６を偏肉パッキン12とともに回動させることで、下流側管路２に対する下流側接続部材６の管底の高さを調整できる。また、上流側接続部材７の他端が偏肉パッキン18を介して上流側管路４の差口５に外挿されるので、上流側管路４に対して上流側接続部材７を偏肉パッキン18とともに回動させることで上流側管路４に対する上流側接続部材７の管底の高さを調整できる。 As described above, according to the repair joint 1, one end of the downstream connection member 6 is inserted into the receiving port 3 of the downstream pipe 2 via the uneven thickness packing 12, so By rotating the downstream connection member 6 together with the uneven thickness packing 12, the height of the tube bottom of the downstream connection member 6 with respect to the downstream pipeline 2 can be adjusted. Further, since the other end of the upstream connection member 7 is extrapolated to the outlet 5 of the upstream pipe line 4 via the uneven thickness packing 18, the upstream connection member 7 is inserted into the uneven thickness packing with respect to the upstream line 4. By rotating together with 18, the height of the pipe bottom of the upstream connection member 7 with respect to the upstream pipe line 4 can be adjusted.

したがって、補修継手１は、下流側接続部材６および上流側接続部材７を回動させるだけでの管底の高さを容易に調整できるため、管底に逆段差が生じにくく、管底の逆段差による排水の流れの阻害を防止でき、排水管路内に汚物等が堆積することを防止できる。 Therefore, since the repair joint 1 can easily adjust the height of the tube bottom by simply rotating the downstream connection member 6 and the upstream connection member 7, a reverse step is unlikely to occur at the tube bottom, and the tube bottom is reversed. It is possible to prevent the flow of waste water from being hindered by a step, and to prevent dirt and the like from accumulating in the drain pipe.

下流側接続部材６は、一端にパッキン取付部10を有するので、下流側接続部材６に対して偏肉パッキン12がより強固に嵌合されて固定されるため、管底を調整する際に下流側接続部材６とともに偏肉パッキン12が回動しやすく、管底の高さを正確に調整できる。 Since the downstream side connection member 6 has the packing mounting portion 10 at one end, the uneven thickness packing 12 is more firmly fitted and fixed to the downstream side connection member 6. The uneven thickness packing 12 is easy to rotate together with the side connection member 6, and the height of the tube bottom can be adjusted accurately.

上流側接続部材７は、他端の接続管部15が第１管部16および第２管部17を有するので、第２管部17に嵌合された偏肉パッキン18が、第１管部16と第２管部17との境界の段差状の部分に係止され、上流側接続部材７に対して偏肉パッキン18がより強固に固定されるため、管底を調整する際に上流側接続部材７とともに偏肉パッキン18が回動しやすく、管底の高さを正確に調整できる。 Since the upstream side connection member 7 has the first pipe part 16 and the second pipe part 17 at the other end of the connection pipe part 15, the uneven thickness packing 18 fitted to the second pipe part 17 has the first pipe part. Since the uneven packing 18 is locked to the stepped portion at the boundary between the first pipe portion 16 and the second pipe portion 17 and more firmly fixed to the upstream connection member 7, the upstream side is adjusted when adjusting the pipe bottom. The uneven packing 18 easily rotates together with the connecting member 7, and the height of the tube bottom can be adjusted accurately.

また、上流側接続部材７が一端側にスライド管部14を有し、ヤリトリ部材８が固定手段23を有することにより、ヤリトリ部材８に対してスライド管部14を摺動させて、ヤリトリ部材８とスライド管部14との重ね合わせ量を変化させることで、下流側管路２と上流側管路４との間における補修継手１の長さを調整できるとともに、調整した状態を固定手段23で固定できるので、補修継手１を容易に設置できる。 Further, since the upstream connection member 7 has the slide tube portion 14 at one end side and the spear member 8 has the fixing means 23, the slide tube portion 14 is slid with respect to the spear member 8, and the spear member 8 The length of the repair joint 1 between the downstream pipe line 2 and the upstream pipe line 4 can be adjusted by changing the amount of overlap between the slide pipe part 14 and the slide pipe part 14, and the adjusted state is fixed by the fixing means 23. Since it can fix, repair joint 1 can be installed easily.

なお、上記第１の実施の形態では、上流側接続部材７にスライド管部14全体が一体に形成された構成としたが、このような構成には限定されず、図７に示す第２の実施の形態のように、スライド管部25が、上流側接続部材７に一体成形された基端部26と、この基端部26に取り付けられ、ヤリトリ部材８の他端に摺動自在に嵌合される延長部27とを有する構成にしてもよい。 In the first embodiment, the entire slide tube portion 14 is integrally formed on the upstream connection member 7. However, the present invention is not limited to such a configuration, and the second embodiment shown in FIG. As in the embodiment, the slide tube part 25 is attached to the base end part 26 integrally formed with the upstream connection member 7 and the base end part 26 and is slidably fitted to the other end of the spear member 8. The extension part 27 may be configured to be joined.

この第２の実施の形態では、延長部27は、一端側に位置した摺動部28と、摺動部28より他端側に位置した取付部29とを有している。 In the second embodiment, the extension portion 27 includes a sliding portion 28 located on one end side and an attachment portion 29 located on the other end side from the sliding portion 28.

摺動部28は、外径がヤリトリ部材８の他端の内径より小径であり、ヤリトリ部材８の他端に摺動自在に嵌合可能である。また、取付部29は、内径が基端部26の外径よりやや大径であり、基端部26に水密に嵌合可能である。 The sliding portion 28 has an outer diameter smaller than the inner diameter of the other end of the spear member 8 and can be slidably fitted to the other end of the spear member 8. The attachment portion 29 has an inner diameter slightly larger than the outer diameter of the base end portion 26 and can be fitted to the base end portion 26 in a watertight manner.

そして、スライド管部25は、取付部29が基端部26に嵌合されて延長部27が取り付けられた状態にて、摺動部28をヤリトリ部材８に対して摺動させることで、ヤリトリ部材８と摺動部28との重ね合わせ量を変化させて、下流側管路２と上流側管路４との間における補修継手１全体の長さを調整できる。 Then, the slide tube part 25 slides the sliding part 28 with respect to the dusting member 8 in a state in which the attaching part 29 is fitted to the base end part 26 and the extension part 27 is attached. The length of the entire repair joint 1 between the downstream pipe line 2 and the upstream pipe line 4 can be adjusted by changing the overlapping amount of the member 8 and the sliding portion 28.

このように、スライド管部25は、基端部26と、この基端部26に取り付けられた延長部27とを有するので、ヤリトリ部材８に対する摺動領域を確保しやすく、補修継手１を最適な長さに調整しやすいため、例えば排水管路の破損箇所が比較的大きい場合などであっても、簡単な構成で容易に破損部分と交換でき、様々な状態の破損に正確に対応できる。 Thus, since the slide tube portion 25 has the base end portion 26 and the extension portion 27 attached to the base end portion 26, it is easy to secure a sliding area for the spear member 8, and the repair joint 1 is optimal. For example, even if the drainage pipe has a relatively large damaged portion, it can be easily replaced with a damaged portion with a simple configuration, and can accurately cope with various states of damage.

次に、本発明の第３の実施の形態を図８ないし図１０を参照して説明する。なお、上記実施の形態と同一の構成及び作用については、同一符号を付してその説明を省略する。 Next, a third embodiment of the present invention will be described with reference to FIGS. In addition, about the structure and effect | action same as the said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図８に示すように、補修継手１は、排水管路の破損部分と交換するため、排水管路の破損部分より下流側の下流側管路２の差口31と、排水管路の破損部分より上流側の上流側管路４の差口５との間に配設される。 As shown in FIG. 8, since the repair joint 1 is exchanged for a damaged portion of the drainage pipe, the outlet 31 of the downstream pipe 2 downstream from the damaged part of the drainage pipe and the damaged part of the drainage pipe It is arrange | positioned between the differential port 5 of the upstream pipe line 4 more upstream.

補修継手１は、下流側管路２の差口31に外挿されて接続される一方側接続部材としての下流側接続部材32と、上流側管路４の差口５に外挿されて接続される上流側接続部材７と、これら下流側接続部材32と上流側接続部材７との間に接続されるヤリトリ部材８とを備えている。 The repair joint 1 is externally connected to the downstream side connection member 32 as one side connection member that is externally connected to the connection port 31 of the downstream side pipe line 2 and the connection port 5 that is connected to the upstream side line 4. The upstream connecting member 7 and the downstream connecting member 32 connected between the downstream connecting member 32 and the upstream connecting member 7 are provided.

下流側接続部材32は、下流側管路２側である一端側に位置する受口33を有している。この受口33は、内径が下流側管路２の差口31の外径より大径である。 The downstream side connection member 32 has a receiving port 33 located on one end side which is the downstream side pipe line 2 side. The receiving port 33 has an inner diameter larger than the outer diameter of the differential port 31 of the downstream side pipe 2.

また、下流側接続部材32は、一端が受口33の他端側に連続して形成された略円筒状の円筒部34を有している。この円筒部34は、ヤリトリ部材８の一端と同径であり、受口33とは反対側の他端が、固定筒部材35を介してヤリトリ部材８の一端に接続されている。 Further, the downstream side connection member 32 has a substantially cylindrical cylindrical portion 34 having one end continuously formed on the other end side of the receiving port 33. The cylindrical portion 34 has the same diameter as one end of the spear member 8, and the other end opposite to the receiving port 33 is connected to one end of the spear member 8 via a fixed cylinder member 35.

固定筒部材35は、内径がヤリトリ部材８および円筒部34の外径よりやや大径であり、一端側に円筒部34が内挿され、他端側にヤリトリ部材８の一端が内挿される。 The fixed cylinder member 35 has an inner diameter slightly larger than the outer diameter of the spear member 8 and the cylindrical portion 34, the cylindrical portion 34 is inserted at one end side, and one end of the spurious member 8 is inserted at the other end side.

上流側接続部材７は、内径が上流側管路４の差口５の外径より大径の接続管部36を有している。 The upstream connection member 7 has a connection pipe part 36 whose inner diameter is larger than the outer diameter of the differential port 5 of the upstream pipe line 4.

下流側接続部材32の受口33および上流側接続部材７の接続管部36には、外側へ突出し内周面が凹んだ取付溝部37が形成されており、この取付溝部37に偏肉パッキン38が嵌合されて取り付けられている。 The receiving port 33 of the downstream connection member 32 and the connection pipe portion 36 of the upstream connection member 7 are formed with an attachment groove portion 37 protruding outward and having a recessed inner peripheral surface. Are fitted and attached.

図９および図１０に示すように、偏肉パッキン38は、周方向に沿って厚みが変化する偏肉部39と、この偏肉部39から周方向の内側へ向かって突出する突出部40とを有する。 As shown in FIGS. 9 and 10, the uneven thickness packing 38 includes an uneven thickness portion 39 whose thickness changes along the circumferential direction, and a protruding portion 40 that protrudes inward in the circumferential direction from the uneven thickness portion 39. Have

偏肉部39は、最も厚みが厚い厚肉部39aと、周方向において厚肉部39aに対向し最も厚みが薄い薄肉部39bとを有し、厚肉部39aから薄肉部39bへ向かって漸次厚みが薄くなっている。また、この偏肉部39には、偏肉パッキン38の止水性や取付溝部37への挿入性を向上させる凹部41が形成されている。 The uneven thickness portion 39 has the thickest portion 39a having the thickest thickness and the thinned portion 39b having the thinnest thickness facing the thick portion 39a in the circumferential direction, and gradually increases from the thick portion 39a to the thin portion 39b. The thickness is thin. Further, the uneven thickness portion 39 is formed with a concave portion 41 that improves the water blocking performance of the uneven thickness packing 38 and the insertion property into the mounting groove portion 37.

突出部40は、基端から先端へ向かって細く形成されており、偏肉部39から傾斜状に突出している。 The protruding portion 40 is formed to be narrower from the proximal end to the distal end, and protrudes from the uneven thickness portion 39 in an inclined shape.

なお、偏肉パッキン38は、突出部40の先端が基端より受口33や接続管部36の基端側に位置するように傾斜して突出した状態で、受口33および接続管部36の内周面に嵌合される。 The uneven thickness packing 38 is in a state where the tip of the protruding portion 40 protrudes from the base end so as to be positioned on the base end side of the receiving port 33 or the connecting pipe portion 36, and the receiving port 33 and the connecting pipe portion 36 are provided. It is fitted to the inner peripheral surface of.

そして、排水管路に補修継手１を配設する際には、下流側接続部材32は、受口33に偏肉パッキン38が嵌合された状態にて偏肉パッキン38を介して下流側管路２の差口31に水密に外挿されるとともに、上流側接続部材７は、接続管部36に偏肉パッキン38が嵌合された状態にて偏肉パッキン38を介して上流側管路４の差口５に水密に外挿される。 When the repair joint 1 is disposed in the drain pipe, the downstream connection member 32 is connected to the downstream pipe via the uneven packing 38 in a state where the uneven packing 38 is fitted to the receiving port 33. The upstream connection member 7 is inserted water-tightly into the differential port 31 of the path 2, and the upstream side connection member 7 is connected to the upstream side pipe line 4 via the uneven thickness packing 38 with the uneven thickness packing 38 fitted to the connection pipe portion 36. It is extrapolated in a watertight manner to the outlet 5.

このような補修継手１によれば、下流側接続部材32の一端である受口33が偏肉パッキン38を介して下流側管路２の差口31に外挿されるので、下流側管路２に対して下流側接続部材32を偏肉パッキン38とともに回動させることで、下流側管路２に対する下流側接続部材32の管底の高さを調整できる。また、上流側接続部材７の他端である接続管部36が偏肉パッキン38を介して上流側管路４の差口５に外挿されるので、上流側管路４に対して上流側接続部材７を偏肉パッキン38とともに回動させることで、上流側管路４に対する上流側接続部材７の管底の高さを調整できる。 According to such a repair joint 1, the receiving port 33, which is one end of the downstream side connection member 32, is extrapolated to the outlet 31 of the downstream side pipeline 2 via the uneven thickness packing 38, so that the downstream side pipeline 2 On the other hand, the height of the pipe bottom of the downstream connection member 32 relative to the downstream pipe line 2 can be adjusted by rotating the downstream connection member 32 together with the uneven thickness packing 38. Further, since the connecting pipe portion 36 which is the other end of the upstream connecting member 7 is extrapolated to the outlet 5 of the upstream pipe line 4 via the uneven thickness packing 38, the upstream side connection to the upstream pipe line 4 is established. By rotating the member 7 together with the uneven thickness packing 38, the height of the pipe bottom of the upstream connection member 7 with respect to the upstream pipe line 4 can be adjusted.

したがって、補修継手１は、下流側接続部材32および上流側接続部材７を回動させるだけで管底の高さを容易に調整できるため、管底に逆段差が生じにくく、管底の逆段差による排水の流れの阻害を防止でき、排水管路内に汚物等が堆積することを防止できる。 Therefore, since the repair joint 1 can easily adjust the height of the tube bottom by simply rotating the downstream connection member 32 and the upstream connection member 7, a reverse step is unlikely to occur at the tube bottom. It is possible to prevent the flow of waste water from being hindered, and to prevent dirt and the like from accumulating in the drain pipe.

また、下流側接続部材32は、受口33を有するので、排水管路の破損分部の下流側近傍に受口33がない場合であっても補修継手１を容易に配設でき、排水管路の補修に際に排水管路の破損範囲に適用しやすい。 Further, since the downstream side connection member 32 has the receiving port 33, the repair joint 1 can be easily arranged even if the receiving port 33 is not provided in the vicinity of the downstream side of the damaged portion of the drainage pipe. Easy to apply to damaged areas of drainage pipes when repairing roads.

偏肉パッキン38は、突出部40を有するので、偏肉パッキン38が嵌合された状態の下流側接続部材32の受口33を下流側管路２の差口31に外挿する際に、突出部40が、差口31の外周面に接触するとともに、挿入にともなって受口33の内径と差口31の外径との差に応じて撓む。 Since the uneven packing 38 has the protruding portion 40, when extrapolating the receiving port 33 of the downstream connection member 32 in a state in which the uneven packing 38 is fitted to the differential port 31 of the downstream pipe line 2, The protrusion 40 contacts the outer peripheral surface of the insertion port 31 and bends according to the difference between the inner diameter of the receiving port 33 and the outer diameter of the insertion port 31 as it is inserted.

したがって、下流側管路２の差口31に下流側接続部材32の受口33を外挿しやすいとともに、下流側管路２の差口31と下流側接続部材32の受口33との接続において、偏肉パッキン38による水密性が良好である。 Accordingly, it is easy to extrapolate the receiving port 33 of the downstream connecting member 32 into the outlet 31 of the downstream side pipe 2, and in connecting the outlet 31 of the downstream side pipe 2 and the receiving port 33 of the downstream side connecting member 32. The water tightness due to the uneven packing 38 is good.

上流側管路４と上流側接続部材７との接続の場合も、同様に、偏肉パッキン38が突出部40を有するので、上流側管路４の差口５に上流側接続部材７の接続管部36を外挿しやすいとともに、上流側管路４の差口５と上流側接続部材７の接続管部36との接続において、偏肉パッキン38による水密性が良好である。 Similarly, in the case of connection between the upstream side pipe line 4 and the upstream side connection member 7, the uneven thickness packing 38 has the protruding portion 40, so that the upstream side connection member 7 is connected to the differential port 5 of the upstream side pipe line 4. It is easy to extrapolate the pipe part 36, and the water tightness by the uneven thickness packing 38 is good in the connection between the differential port 5 of the upstream side pipe 4 and the connection pipe part 36 of the upstream side connection member 7.

なお、この第３の実施の形態のように下流側管路２の差口31に下流側接続部材32の受口33を外挿する場合は、偏肉パッキン38を用いる構成には限定されず、第１の実施の形態および第２の実施の形態の上流側接続部材７と同様に偏肉パッキン18を用いてもよい。 In the case where the receiving port 33 of the downstream connection member 32 is extrapolated to the differential port 31 of the downstream side pipe line 2 as in the third embodiment, the configuration is not limited to the configuration using the uneven thickness packing 38. Similarly to the upstream connection member 7 of the first embodiment and the second embodiment, the uneven packing 18 may be used.
