る方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for connecting corrugated pipes. More specifically, the present invention relates to a method for connecting corrugated pipes having spiral irregularities in the circumferential direction and used as protection pipes for power cables, drain pipes, etc.
従来、この種のコルゲート管を接続する方法としては、
接続すべき２本の管の接合部外周面に、弾性材料からな
るシール材を介してゴム環体を接合部に跨って嵌設し、
更に該ゴム環体の上からカップリングバンドを嵌合し緊
締するものが、提供されている。Conventionally, the method for connecting this type of corrugated pipe is as follows:
A rubber ring is fitted to the outer peripheral surface of the joint of two pipes to be connected, spanning the joint through a sealing material made of an elastic material,
Furthermore, a device is provided in which a coupling band is fitted and tightened from above the rubber ring.
また、ネジ部を有する円筒状で、該ネジ部がその途中に
おいて逆方向になっている継手を使用し、継手の両端に
管端部を臨ませて継手を回動する接続方法も知られてい
る。Furthermore, a connection method is also known in which a cylindrical joint with a threaded part is used, and the threaded part is oriented in opposite directions midway through the joint, and the joint is rotated with the pipe ends facing both ends of the joint. There is.
上記従来の技術のうち前者は、シール材及びゴム環体が
管体の接合部外周面に密着し、水密性が高められて漏水
を防ぐことができるが、接続するのに多くの部材を必要
とし、しかも、面倒である他、管体が引張られたときに
抜き出るおそれがある等、接続力が弱いという問題があ
った。In the former of the above conventional techniques, the sealing material and the rubber ring stick closely to the outer circumferential surface of the joint of the pipe body, increasing watertightness and preventing water leakage, but it requires many members to make the connection. However, in addition to being troublesome, there was a problem that the connection force was weak, such as the possibility that the tube could be pulled out when it was pulled.
また、後者においては、接続するに要する部材が少なく
て済み、簡単に接続することができるものの、シール材
を介装し得ないのでシール性に欠け、しかも、この場合
には、接続すべき２本の管は予め逆方向に螺旋状の凹凸
が設けられていなければ接続することができないという
問題点を有していた。In the latter case, the number of members required for connection is small and the connection is easy, but since a sealing material cannot be inserted, the sealing performance is lacking. The problem with real pipes is that they cannot be connected unless they are previously provided with spiral irregularities in opposite directions.
本発明は、上述のような従来の問題点に鑑みなされたも
ので、その目的とするところは、極〈少ない部材によっ
てシール性に優れ、簡単にして強固に接続することがで
きるコルゲート管の接続方法を提供するものである。The present invention was made in view of the conventional problems as described above, and its purpose is to connect corrugated pipes that can be easily and firmly connected with excellent sealing performance using extremely few members. The present invention provides a method.

。The present invention is a method for connecting two pipes having spiral irregularities in the circumferential direction using a joint body. The joint body includes a threaded portion that can be screwed onto the outer periphery of the tube, and sleeve portions that extend from both ends of the threaded portion and can be fitted onto the outer surface of the tube. Then, a sealing material is interposed on the outer circumferential surface of the joint of one of the pipes to be connected or on the inner circumferential surface of one sleeve portion of the joint body,
The sleeve portion is fitted onto the joint end of the chain pipe, the joint body is rotated, and the joint end of the pipe is made to reach the other sleeve portion of the joint body.Next, the inner peripheral surface of this other sleeve portion or by interposing a sealant on the outer peripheral surface of the joint of the other pipe,
The sleeve portion is fitted onto the joint end of the chain pipe, and the joint end is abutted against the joint end of the - side tube. After that, the joint body is characterized in that it rotates in the opposite direction.
本発明の方法においては、２本の管を完全に接続する前
にシーリング材が介在され、このシーリング材は管が完
全に接続された状態では管の接合部外周面と継手体のス
リーブ部の内周面とに密着するようになる。In the method of the present invention, a sealing material is interposed before the two pipes are completely connected, and when the pipes are completely connected, the sealing material is attached to the outer circumferential surface of the joint of the pipes and the sleeve portion of the joint body. It comes into close contact with the inner peripheral surface.
また、２本の管の接合端部が突合されてそれら間に間隙

されるものである。As shown in FIG. 1, the method for connecting corrugated pipes according to the present invention consists of two pipes 1. made of a flexible material such as synthetic resin and having a spiral concave portion 3 and a convex portion 4 in the circumferential direction. In this method, a joint body 5 is used to connect the chain pipes 1 and 2. The joint body 5 is made of a flexible material such as synthetic resin, and as shown in FIG. The threaded part 6 is screwed onto the outer periphery of the joint of the tube 1.2, and the sleeve part 7.8 can be fitted onto the outer surface of the tube 1.2. The lengths of the threaded part 6, sleeve parts 7 and 8 may be set as appropriate, but the length of the sleeve part 7 is the sum of half of the threaded part 6 and the sleeve part 8 (Lr =-!=-L-+
L3) is optimal, and sealing material is applied to the outer peripheral surface of the joint of one of the two pipes 1.2 to be connected or the inner peripheral surface of one sleeve portion 7 of the joint body 5. Interpose 9. As the sealing material 9, silicone resin,
Viscoelastic materials such as butyl rubber, rubber packing, etc. are suitable. Pipe 1 with this sealing material 9 interposed
The sleeve portion 7 of the joint body 5 is fitted into the joint end portion of the joint body 5, and the joint body 5 is rotated. Then, the threaded part 6 of the joint body 5
is screwed onto the outer peripheral surface of the joint part of the pipe 1, and as shown in FIG.
reach. That is, the joint body 5 is rotated until the joint end of the pipe 1 reaches the boundary between the threaded part 6 and the other sleeve part 8, and when that point is reached, the rotation of the joint body 5 is stopped. A sealing material 10 is interposed on the inner circumferential surface of the other sleeve portion 8 or the outer circumferential surface of the other pipe 2 to be connected. This sealing material 10 is made of the same material as the aforementioned sealing material 9, and both are interposed before the two pipes 1.2 are completely connected. Then, as shown in FIG. 4, the sleeve part 8 of the joint body 5 is fitted into the joint end of the pipe 2, and the joint end of the pipe 2 is butted against the joint end of the pipe l inside the joint body 5. let In this way, the joint ends of pipe 1 and pipe 2 will come into close contact with each other, leaving no gap between them. rotate in the direction. Due to this rotation, the threaded part 6 of the joint body 5 is screwed into the outer peripheral surface of the joint part of the pipe 2, and the joint body 5 is screwed into the joint part outer peripheral surface of the pipe 2.
side to the tube 2 side. The rotation of the joint body 5 is stopped when the approximately central portion of the threaded portion 6 of the joint body 5 reaches the abutting portion of the pipes 1 and 2. Then, as shown in Figure 1,
The threaded portion 6 of the joint body 5 is screwed across the outer peripheral surface of the joint portion of both tubes 1.2. Further, the sealing material 9 is applied between the outer peripheral surface of the joint of the pipe 1 and the inner peripheral surface of the sleeve portion 7 of the joint body 5, and the sealing material 10 is applied between the outer peripheral surface of the joint of the pipe 2 and the sleeve portion of the joint body 5. The tubes 1 and 2 are completely connected by being interposed between the tubes 8 and the inner circumferential surfaces of the tubes 8 and coming into close contact with them.

として種々の効果を奏するものである。As described above, the method of the present invention uses a sealing material before connecting the pipes, and the connection is performed by rotating the joint body.
Pipes can be easily connected. In addition, since the ends of the connected pipes are in close contact with each other, fluid flows smoothly, and the pipes and the joint body are in close contact with the sealing material, increasing watertightness and eliminating the risk of water leakage. Since the threaded portion is screwed across the outer circumferential surface of the joint of both pipes, this method provides various effects as a method for connecting corrugated pipes, such as a strong connection and no possibility of the pipes being pulled out.
