Description

이음구조를 가진 합성수지관의 구조Structure of synthetic resin pipe with joint structure

본발명은 상수관 또는 하수관으로 사용되는 직경이 약 200㎜ 이상되는 통상의 합성수지관 양끝단부에 플렌지를 형성하되, 한쪽 플렌지에는 삽입돌부를 형성하고, 다른 한쪽 플렌지는 삽입요부를 형성하여 여러개의 합성수지관을 연결시킬 때 작업이 매우 손쉽게 이루어져서 공사기간 단축 인력 및 시간절감, 그리고 완전한 누수예방으로 신뢰성을 극대화시킬수 있도록 하기위한 이음구조를 가진 합성수지관의 구조에 관한 것이다.In the present invention, a flange is formed at both ends of a conventional synthetic resin pipe having a diameter of about 200 mm or more, which is used as a water pipe or sewage pipe, and an insertion protrusion is formed on one flange, and the other flange forms an insertion recess to form a plurality of synthetic resins. It is related to the structure of synthetic resin pipe with joint structure to maximize the reliability by shortening construction period, manpower and time saving, and complete leakage prevention when connecting pipes.

Various types of products are used, such as expansion into a mold or flanges formed at both ends, and are generally used when connecting pipes in the form of pipes.

Two joint members of the type are wound several times with the sealing sheet on the part where the two pipes are connected, and then assembled and fixed using bolts and nuts, or made of stainless steel.

The type joint member was wound several times on the part where two pipes are connected, and then heated with a torch lamp, etc., and then assembled using bolts or nuts. It was difficult to maintain watertightness, and after the connection, there was a high possibility that the pipe would be dislodged.

In the case of the pipe formed with the flange of the type, the end surface of the flange is formed in a flat surface.

It is also easy to assemble in the state of working conditions (because it is working in the excavated ground) because it is assembled in the form of mold and it is difficult to maintain perfect watertightness. This also followed a lot of closures.

따라서 본발명은 종래 합성수지관의 제반문제점을 감안하여 발명한 것으로서,특히 합성수지 관체 양단부에 플렌지를 형성하되 한쪽에는 삽입돌부를 그리고 다른 한쪽에는 삽입요부를 형성하여 삽입돌부가 삽입요부에 끼워진 상태에서 보울트 및 너트로 조립고정되게 함으로써 별도의 이음부재없이 이음조립이 용이하게 이루어지고, 이에따라 작업성이 매우 좋도록 하려는데 목적이 있는 것이다.Therefore, the present invention has been invented in view of various problems of the conventional synthetic resin pipe, and particularly, a flange is formed at both ends of the synthetic resin pipe, but an insertion protrusion is formed on one side and an insertion recess on the other side so that the bolt is inserted in the insertion recess. And by assembling and fixing with a nut is easy to assemble the joint without a separate joint member, and the purpose is to make workability very good accordingly.

또한 상기한 삽입돌부의 길이는 삽입요부의 깊이보다 약간더 길게 형성하고 삽입돌부 외주면과 삽입요부 내경부분은 약간 테이퍼진 구성으로 형성함으로써 이음작업시 매우 견고하게 맞물려 누수등의 염려없이 완벽한 수밀유지가 이루어지게 하는데도 발명의 목적이 있는 것이다.In addition, the length of the insertion protrusion is slightly longer than the depth of the insertion recess, and the outer peripheral surface of the insertion protrusion and the inner diameter of the insertion recess are formed in a slightly tapered configuration, so that the joint is very firmly engaged during jointing operation so that perfect watertightness is maintained without fear of leakage. It is also an object of the invention to achieve.
