Description

本発明は排水管や上水管などの管継手に関し、特に、配管の補修に適した管継手に関する。   The present invention relates to pipe joints such as drain pipes and water pipes, and more particularly to pipe joints suitable for pipe repair.

排水管や給水管等の管路では、管路の一部が破損した場合、その部分を切断して除去し、切断した部分に管継手を接続して修復することが行われている。   In a pipe line such as a drain pipe or a water supply pipe, when a part of the pipe line is broken, the part is cut and removed, and a pipe joint is connected to the cut part for repair.

図４は、排水管における従来の修復手順を説明する図である。（ａ）に示すように、たとえば、排水管の管１に欠陥孔２が開いてしまった場合、欠陥孔２を含む範囲を所定の間隔をあけた２本の点線に示す位置で切断し、（ｂ）に示す状態にする。   FIG. 4 is a diagram for explaining a conventional repair procedure for a drain pipe. As shown in (a), for example, when the defective hole 2 has been opened in the pipe 1 of the drain pipe, the range including the defective hole 2 is cut at a position indicated by two dotted lines spaced by a predetermined interval, The state shown in FIG.

次に、（ｃ）に示すように、やりくり管と称される管継手３を、一方側の管１に矢印に示すように斜めに差し込み、他端が他方の管１に当たらない位置まで押し込む。   Next, as shown in (c), the pipe joint 3 referred to as the end pipe is inserted into the pipe 1 on one side obliquely as shown by the arrow, and the other end is pushed into a position where it does not hit the other pipe 1. .

（ｄ）に示すように、管継手３を排水管と平行にし、少し引き戻して両端に管１、１が入るようにする。この後、つなぎ目を封止することで、修復が完了する。   As shown in (d), the pipe joint 3 is made parallel to the drainage pipe, and is pulled back slightly so that the pipes 1 and 1 are inserted at both ends. Thereafter, the joint is sealed to complete the repair.

この方法は、管継手３の内径を管１の外径よりかなり大きくし、かつ、（ａ）に示す２本の点線間の距離を大きくする必要があり、距離を大きくとれない場合など、作業が非常にやり難くなる場合が多い。また、管継手３と管１の径に差があるので、隙間を完全に封止するのも困難である。   In this method, it is necessary to make the inner diameter of the pipe joint 3 considerably larger than the outer diameter of the pipe 1 and to increase the distance between the two dotted lines shown in FIG. Is often very difficult to do. Moreover, since there is a difference in the diameters of the pipe joint 3 and the pipe 1, it is difficult to completely seal the gap.

図５は、特許文献１（特開平９−３１７９６５）に記載されたまた別の従来の補修方法を示す図である。これは、管１の欠陥個所を切断した後、柔軟な素材からできた管継手４を使用する方法である。管継手４は、１個所に分割部を有し、分割部の一方に凸部４ａを形成し、分割部の他方に凸部４ａが係合する嵌合溝４ｂを形成したものである。管継手４が柔軟な素材なので、分割部を拡げることで、管１を図５に示すように囲むことができる。この後、凸部４ａを嵌合溝４ｂに嵌合させることで、管継手４の分割部を封止する。この方法であれば、作業が容易であり、しかも、管継手４の内径を管１の外径に合わせることができ、封止も容易にできる。   FIG. 5 is a diagram showing another conventional repair method described in Patent Document 1 (Japanese Patent Laid-Open No. 9-317965). This is a method of using the pipe joint 4 made of a flexible material after cutting the defective portion of the pipe 1. The pipe joint 4 has a split portion at one place, a convex portion 4a is formed on one side of the split portion, and a fitting groove 4b is formed on the other side of the split portion to engage the convex portion 4a. Since the pipe joint 4 is a flexible material, the pipe 1 can be surrounded as shown in FIG. Then, the division part of the pipe joint 4 is sealed by fitting the convex part 4a into the fitting groove 4b. With this method, the operation is easy, and the inner diameter of the pipe joint 4 can be matched with the outer diameter of the pipe 1 and sealing can be performed easily.

しかしながら、分割部を大きく拡げて管１を囲うので、素材はかなり柔軟なものでなければならない。そのため、材料が限定され、しかも、強度が必要な個所には使用できない。   However, the material must be quite flexible since the dividing part is greatly expanded to enclose the tube 1. Therefore, the material is limited, and it cannot be used in places where strength is required.

以上の他に、特許文献２（特開２００１−３４９４７７）では、蛇腹状のフレキシブルホースを用いた管継手を提案している。蛇腹状の部分を縮めることで、排水管を切断した個所に挿入し、挿入してから蛇腹部分を伸ばして両側の排水管と接続するのである。 In addition to the above, Patent Document 2 (Japanese Patent Laid-Open No. 2001-349477) proposes a pipe joint using a bellows-like flexible hose. By shrinking the bellows-shaped part, the drainage pipe is inserted into the cut portion, and after insertion, the bellows part is extended and connected to the drainage pipes on both sides.

しかしながら、特許文献３に記載の管継手も、素材が蛇腹などのフレキシブルな構造なので、硬く、強度のある素材を使用することができなかった。そのため、使用できる個所が限定されていた。   However, since the material of the pipe joint described in Patent Document 3 is a flexible structure such as a bellows, a hard and strong material cannot be used. Therefore, the place which can be used was limited.

本発明は、斯かる実情に鑑み、柔軟な素材でも使用できるとともに、硬く、強度のある素材でも使用することができ、しかも、接続作業が容易な管継手を提供することを目的としている。   In view of such circumstances, the present invention has an object to provide a pipe joint that can be used with a flexible material, can be used with a hard and strong material, and can be easily connected.

上記の目的を達成するために、本発明の管継手は、筒状体をその長さ方向に沿って２つに切断した第１管継手半体および第２管継手半体と、前記第１管継手半体と第２管継手半体のいずれか一方に形成した係止部と、いずれか他方に形成した被係止部とを有し、係止部と被係止部とが係合することで、第１管継手半体と第２管継手半体とが結合して筒状体となることを特徴としている。   In order to achieve the above object, a pipe joint according to the present invention includes a first pipe joint half and a second pipe joint half obtained by cutting a cylindrical body into two along a length direction thereof, and the first pipe joint. It has a locking part formed in either one of the pipe fitting half and the second pipe fitting half, and a locked part formed on either of them, and the locking part and the locked part are engaged. By doing so, the first pipe joint half and the second pipe joint half are combined to form a cylindrical body.

前記第１管継手半体又は第２管継手半体のいずれか一方の切断部に、外周壁を延長して可撓片を形成し、該可撓片の先端に前記係止部としての凸部を形成し、前記第１管継手半体又は第２管継手半体のいずれか他方に、前記可撓片と重なる突起部を形成し、該突起部に前記被係止部としての凹部を形成した構成としてもよい。   A flexible piece is formed by extending an outer peripheral wall at one of the cut portions of the first pipe joint half or the second pipe joint half, and a protrusion as the locking portion is formed at the tip of the flexible piece. Forming a protruding portion that overlaps the flexible piece on the other of the first pipe fitting half and the second pipe fitting half, and forming a recess as the locked portion on the protruding portion. It is good also as the formed structure.

前記凸部及び凹部が、前記第１管継手半体と第２管継手半体の長さ全体に形成されている構成とすることができる。   The said convex part and a recessed part can be set as the structure currently formed in the whole length of the said 1st pipe joint half and the 2nd pipe joint half.

また、前記第１管継手半体と第２管継手半体とが、両端部に大径部を有するとともに両端の大径部の間に小径部を有し、前記第１管継手半体と第２管継手半体とが結合して筒状体となったとき、筒状体の両端部に、接続する管路の外径とほぼ同じ大きさの内径を有し、中間部が前記接続する管路の内径とほぼ同じ大きさの内径を有する段付き孔を有する構成としてもよい。   In addition, the first pipe joint half and the second pipe joint half have a large diameter part at both ends and a small diameter part between the large diameter parts at both ends, and the first pipe joint half and When the second pipe joint halves are combined to form a cylindrical body, both ends of the cylindrical body have an inner diameter that is substantially the same as the outer diameter of the pipe line to be connected, and the intermediate portion is the connection It is good also as a structure which has the stepped hole which has an internal diameter substantially the same magnitude | size as the internal diameter of the pipe line to make.

排水管や給水管などの配管に、孔などの欠陥ができた場合、本発明の管継手の長さに適した長さの配管を切断して除去する。そして、離間した両側の配管の下側に、第１管継手半体を挿入する。第１管継手半体は、円筒などの筒状体を半割にしているので、簡単に配管の下側に挿入することができる。下側に第１管継手半体をセットしたら、上から第２管継手半体を載せ、係止部と被係止部を係合して結合する。配管は、筒状になった管継手の両端に入り込み接続される。この接続作業は、配管と管継手のつなぎ目を目視によって確認しながら行うことができ、確実な接続作業が行える。   When a defect such as a hole is formed in a pipe such as a drain pipe or a water supply pipe, the pipe having a length suitable for the length of the pipe joint of the present invention is cut and removed. Then, the first pipe joint half is inserted below the pipes on both sides that are separated from each other. Since the first pipe joint half halves a cylindrical body such as a cylinder, it can be easily inserted under the pipe. When the first pipe joint half is set on the lower side, the second pipe joint half is placed from above, and the locking portion and the locked portion are engaged and coupled. The pipe enters and is connected to both ends of a tubular pipe joint. This connection work can be performed while visually confirming the joint between the pipe and the pipe joint, and a reliable connection work can be performed.

第１管継手半体と第２管継手半体の接合面に接着剤と塗布しておけば、接着剤により結合強度を上げ、かつ、シーリング効果も向上させることができる。また、筒状体の両端部の内径が配管の外径と同じになるようにすれば、シーリングも容易になる。   If an adhesive is applied to the joint surface between the first pipe joint half and the second pipe joint half, the bonding strength can be increased by the adhesive and the sealing effect can be improved. In addition, sealing is facilitated if the inner diameter of both ends of the cylindrical body is the same as the outer diameter of the pipe.

なお、排水管の継手として使用する場合、排水管は通常、管の１／２以下しか流れていないので、シーリングがされていなくても十分な場合もある。   When used as a drainage pipe joint, since the drainage pipe usually flows only 1/2 or less of the pipe, it may be sufficient even if it is not sealed.

第１管継手半体と第２管継手半体の結合力を大きくする必要がある場合には、第１管継手半体と、第２管継手半体を結合して筒状体にしてから、その外側を金属製のバンドで締め付けて固定してもよい。   When it is necessary to increase the coupling force between the first pipe joint half and the second pipe joint half, the first pipe joint half and the second pipe joint half are joined to form a cylindrical body. The outer side may be fixed with a metal band.

係止部と被係止部とが、凸部と凹部とから構成されると、第１管継手半体と、第２管継手半体の結合を容易にすることができる。凸部及び凹部が、前記第１管継手半体と第２管継手半体の長さ全体に形成されている構成とすれば、結合力を上げることができる。   When the locking part and the locked part are constituted by the convex part and the concave part, it is possible to facilitate the coupling of the first pipe joint half and the second pipe joint half. If a convex part and a recessed part are set as the structure currently formed in the whole length of the said 1st pipe joint half body and a 2nd pipe joint half body, a coupling force can be raised.

第１管継手半体と、第２管継手半体とが結合してできる筒状体が、両端部に、接続する管路の外径とほぼ同じ大きさの内径を有し、中間部が前記接続する管路の内径とほぼ同じ大きさの内径を有する段付き孔の構成にすると、管継手の部分も管の部分と同じ内径となり、流れをスムーズにし、ごみなどが溜まるのを防止することができる。   A cylindrical body formed by combining the first pipe joint half and the second pipe joint half has an inner diameter that is substantially the same as the outer diameter of the pipe line to be connected at both ends, and the intermediate part is When a stepped hole having an inner diameter that is approximately the same size as the inner diameter of the pipe line to be connected is used, the pipe joint portion also has the same inner diameter as the pipe portion, smoothing the flow and preventing dust and the like from accumulating. be able to.

以下、本発明の実施例を図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the drawings.

It is a front view of the state where the 2nd pipe joint half was separated. 2A is a perspective view showing a state before the first pipe joint half and the second pipe joint half are joined, FIG. 2B is a perspective view showing the joined state, and FIG. 3 is the first pipe. It is expanded sectional drawing of the state which couple | bonded the coupling half and the 2nd pipe coupling half.

本発明の管継手１００は、円筒形状の管を、その長さ方向に沿って２つに分割した第１管継手半体１１０と、第２管継手半体１２０とから構成されている。この実施例では、円筒形状であるが、筒状であればよく、楕円形や卵型でもよい。   The pipe joint 100 of the present invention includes a first pipe joint half 110 and a second pipe joint half 120 obtained by dividing a cylindrical pipe into two along the length direction thereof. In this embodiment, the shape is cylindrical, but it may be cylindrical, and may be oval or egg-shaped.

第１管継手半体１１０は、断面形状がほぼ半円形状で、両端に半円と同じ曲率中心を持った突起部１１１が延設されている。突起部１１１の下端には凹部からなる被係止部１１２が形成されている。また、両端には大径部１１３があり、大径部１１３、１１３の中間は小径部１１４となって段付きの径となっている。   The first pipe joint half 110 has a substantially semicircular cross-sectional shape, and projecting portions 111 having the same center of curvature as the semicircle extend at both ends. At the lower end of the protruding portion 111, a locked portion 112 made of a concave portion is formed. In addition, there are large-diameter portions 113 at both ends, and a middle diameter between the large-diameter portions 113 and 113 is a small-diameter portion 114 having a stepped diameter.

第２管継手半体１２０は、断面形状が第１管継手半体１１０と同様の半円形状で、半円の両端に半円の円弧の一部を薄肉にした可撓片１２１が形成されている。可撓片１２１の先端には、凸部状の係止部１２２がある。また、第１管継手半体１１０と同様に、両端には大径部１２３があり、大径部１２３、１２３の中間は小径部１２４となって段付きの径となっている。   The second pipe joint half 120 has a semicircular cross-sectional shape similar to that of the first pipe joint half 110, and a flexible piece 121 is formed by thinning a part of a semicircular arc at both ends of the semicircle. ing. At the tip of the flexible piece 121, there is a convex locking portion 122. Further, similarly to the first pipe joint half 110, there are large-diameter portions 123 at both ends, and a middle diameter between the large-diameter portions 123 and 123 becomes a small-diameter portion 124 to have a stepped diameter.

次に、上記管継手１００の使用方法を説明する。   Next, a method for using the pipe joint 100 will be described.

まず、図４の従来例で説明したように、配管の不良部分を所定の長さだけ切断して取り除き、図４（ｂ）に示す状態にする。すなわち、使用する管継手１００が決まれば、管継手１００の小径部１１４の長さも決まる。そこで、不良部分を切断して除去する場合は、小径部１１４の長さに合わせて切断する。   First, as described in the conventional example of FIG. 4, the defective portion of the pipe is cut and removed by a predetermined length to obtain the state shown in FIG. That is, if the pipe joint 100 to be used is determined, the length of the small diameter portion 114 of the pipe joint 100 is also determined. Therefore, when the defective portion is cut and removed, it is cut according to the length of the small diameter portion 114.

次に、図３（ａ）に示すように、第１管継手半体１１０を管１、１の下側に挿入する。このとき、大径部１１３は、と、小径部１１４との段差の位置に、両側の管１，１の先端がくる。この状態で第１管継手半体１１０を下から支え、上から第２管継手半体１２０を被せる。このとき、第２管継手半体１２０の可撓片１２１が外側に弾性変形し、係止部１２２の凸部が突起部１１１を乗り越えてくる。そして、係止部１２２が被係止部１１２に重なると凸部が凹部に嵌入し、図３（ｂ）に示すように、第１管継手半体１１０と第２管継手半体１２０とが結合する。第１管継手半体１１０と第２管継手半体１２０とが結合すると、管継手１００の外側は円筒面となり、管１より若干太い筒状体となる。


Next, as shown in FIG. 3A, the first pipe joint half 110 is inserted below the pipes 1 and 1. At this time, the large diameter portion 11 3, and the position of the step between the small-diameter portion 114, comes tips of both sides of the tube 1,1. In this state, the first pipe joint half 110 is supported from below, and the second pipe joint half 120 is covered from above. At this time, the flexible piece 121 of the second pipe joint half 120 is elastically deformed outward, and the convex portion of the locking portion 122 gets over the protruding portion 111. And when the latching | locking part 122 overlaps with the to-be-latched part 112, a convex part will fit in a recessed part, and as shown in FIG.3 (b), the 1st pipe joint half body 110 and the 2nd pipe joint half body 120 will become. Join. When the first pipe joint half 110 and the second pipe joint half 120 are coupled, the outside of the pipe joint 100 becomes a cylindrical surface, and becomes a cylindrical body slightly thicker than the pipe 1.


以上の接続作業は、目視により接続状態を確認しながら行うことができ、確実な接続を行うことができる。   The above connection work can be performed while visually confirming the connection state, and a reliable connection can be made.

第１管継手半体１１０と第２管継手半体１２０を結合させる前に、可撓片１２１の内側と係止部１２２の各面、突起部１１１の外側面と被係止部１１２の内面、すなわち、接触面に接着剤を塗布しておけば、第１管継手半体１１０と第２管継手半体１２０を結合させた後、接着剤で結合を固定することができる。   Before joining the first pipe joint half 110 and the second pipe joint half 120, the inner side of the flexible piece 121, each surface of the locking portion 122, the outer surface of the projection 111, and the inner surface of the locked portion 112. That is, if an adhesive is applied to the contact surface, after the first pipe joint half 110 and the second pipe joint half 120 are joined, the joint can be fixed with the adhesive.

管１が排水用管の場合、排水は管１の半分程度を満たす程度なので、接着剤を使用しなくても水漏れが起こらない場合もある。しかし、接着剤で接着することで、つなぎ目を密閉することができ、封止効果を上げることができる。   In the case where the pipe 1 is a drain pipe, the drainage is only about half of the pipe 1 and therefore water leakage may not occur even without using an adhesive. However, by bonding with an adhesive, the joint can be sealed, and the sealing effect can be increased.

また、図２に示すように、管継手１００と管１との接合部に、必要に応じてＯリングなどのパッキン１３０を挿入すると気密に密閉することが可能となる。パッキン１３０の取付溝は、第１管継手半体１１０と第２管継手半体１２０に形成しておくとよい。   Moreover, as shown in FIG. 2, if packing 130, such as an O-ring, is inserted in the junction part of the pipe joint 100 and the pipe 1 as needed, it will become airtightly sealed. The attachment groove of the packing 130 may be formed in the first pipe joint half 110 and the second pipe joint half 120 in advance.

なお、大径部１１３、１２３で形成する円の径は、管１の外径とほぼ同じにしておくことで、接着剤程度でも管１に管継手１００を固定することができる。しかし、管継手１００の結合の永続性を保証する必要がある場合や、管継手１００の強度が必要な場合は、図３（ｂ）に示した状態の管継手１００の外側に金属バンドなどで締付固定するとよい。   It should be noted that the diameter of the circle formed by the large diameter portions 113 and 123 is substantially the same as the outer diameter of the pipe 1, so that the pipe joint 100 can be fixed to the pipe 1 even with an adhesive. However, when it is necessary to guarantee the durability of the coupling of the pipe joint 100 or when the strength of the pipe joint 100 is necessary, a metal band or the like is provided outside the pipe joint 100 in the state shown in FIG. Tighten and fix.

また、小径部１１４、１２４で作る円の径を管１の内径と同じにすることで、管路としては、径の変化のない状態にすることができ、流れが淀んだり、ごみが溜まるなどの問題を予防することができる。   Moreover, by making the diameter of the circle formed by the small diameter portions 114 and 124 the same as the inner diameter of the pipe 1, the diameter of the pipe can be kept unchanged, the flow is stagnant, and dust is collected. Can prevent problems.

本発明の管継手１００は、可撓片１２１に適当な可撓性を持たせることができれば、素材は特に限定されない。塩ビを初めとする各種のプラスチック、鋼鉄などの金属、等、種々の素材を使用することができる。また、可撓片１２１は必須ではなく、係止部と被係止部を設ければよい。   The pipe joint 100 of the present invention is not particularly limited as long as the flexible piece 121 can have appropriate flexibility. Various materials such as various plastics such as vinyl chloride, metals such as steel can be used. Further, the flexible piece 121 is not essential, and a locking portion and a locked portion may be provided.

また、第１管継手半体１１０に被係止部１１２を形成し、第２管継手半体１２０に係止部１２２を設けたが、逆にしてもよい。また、係止部１２２と被係止部１１２とは、実施例のもの以外の種々の形状のものを使用することができる。   Moreover, although the to-be-latched part 112 was formed in the 1st pipe joint half 110, and the latching part 122 was provided in the 2nd pipe joint half 120, you may make it reverse. Moreover, the thing of various shapes other than the thing of an Example can be used for the latching | locking part 122 and the to-be-latched part 112. FIG.
