본 발명은 유체이송관의 배관을 위한 이음구에 관한 것으로서, 보다 구체적으로는 상수관의 배관시 주철관, PE피복강관, PVC관 등의 유체이송관을 활용함에 있어서 설치에 소요되는 외형 치수를 작게 하면서 작업성이 양호하여 공수를 절감할 수 있는 유체이송관의 배관을 위한 이음구에 관한 것이다.The present invention relates to a joint for a pipe of a fluid transfer pipe, and more particularly, in the use of fluid transfer pipes such as cast iron pipe, PE coated steel pipe, PVC pipe, etc., during the piping of water pipe workability while reducing the external dimensions required for installation This satisfies the fitting for the piping of the fluid transfer pipe can reduce the man-hour.

일반적으로 상수도 관로는 방대한 양의 급수체계를 유지하는 중요한 요소로서 강도가 비교적 크고 내구성이 있어야 하고, 시공이 간편하고 신뢰성이 있어야 하고, 녹에 의한 부식에 저항력을 지녀야 한다. 이에 따라 주기적인 교체공사를 통하여 누수, 부식 및 노후화 등의 문제점을 해결하고 있다.In general, the water supply pipe is an important element to maintain a large amount of water supply system, which should be relatively strong and durable, easy to install and reliable, and resistant to rust corrosion. Accordingly, through periodic replacement works, problems such as leakage, corrosion, and aging are solved.

한국 등록실용신안공보 제0282278호의 "합성수지관의 관이음구"에 의하면 『관체로 내주연에 관체의 선단이 결합되는 바디와, 링형상으로 바디의 양단 내측과 관체의 외주연 사이에 위치되어 바디 내측면을 밀폐시키는 밀폐링과, 두 개의 반원형 링체로 이루어져 연결되는 관체의 선단부에 미리 고정볼트에 의해 완강히 고정되고 밀폐링의 외측면과 완강히 밀착됨으로써 밀폐링의 압착 수밀을 보장함과 동시에 관체의 이탈을 방지하는 반원홀더와, 관체로 반원홀더 외측의 관체 외주연에 끼 워져 체결수단에 의해 완강히 고정되는 캡을 구비』한다.According to "Pipe joint of synthetic resin pipe" of Korean Registered Utility Model Publication No. 0282278, `` The body is joined to the inner circumference of the tube by the tube, and the ring is located between the inner ends of the body and the outer periphery of the tube in a ring shape. The sealing ring that seals the side and the semi-circular ring body are secured by fixing bolts in advance to the front end of the pipe connected to each other, and firmly in close contact with the outer surface of the sealing ring, thereby ensuring the press-tightness of the sealing ring and at the same time leaving the tube. And a semi-circle holder for preventing the plug, and a cap fitted into the outer circumference of the tube outside the semi-circle holder and being firmly fixed by the fastening means.

이는 현장에서의 관이음 작업시간을 최소로 단축하고, 100mm이상의 대형 관체라도 관이음작업이 가능하다고 기술하지만, 연결부분의 길이가 길어 시공이 불편하므로 다양한 배관이음에 적용하기에 무리가 따른다.This shortens the time of pipe joint work in the field and describes that pipe joint work is possible even with large pipes of 100mm or more, but it is difficult to apply to various pipe joints because the length of connection part is inconvenient to construct.

또, 한국 등록실용신안 제0444734호의 "합성수지관용 이탈방지 조인트"에 의하면 『관이음을 위한 두 관 중 플랜지를 갖는 일측관에 설치되며 타측관 방향으로 돌출된 걸림턱을 갖는 압륜과, 상기 타측관과 쐐기에 의해 결합되며 상기 걸림턱과 결합되는 또 다른 걸림턱이 구비되어 압륜과 결합되는 클램프와, 상기 두 관의 사이에 설치되어 유체의 누설을 방지하는 패킹재로 구성된 이탈방지 조인트에 있어서, 상기 클램프는 타측관과의 결합을 위한 쐐기를 내면에 갖는 2개의 결속부재가 상호 결합되어 타측관의 외면을 감싸도록 구성』된다.In addition, according to the Korean Registered Utility Model No. 0444734, "Prevention Prevention Joint for Synthetic Resin Pipe", "A pressure pipe is installed in one pipe having a flange of two pipes for jointing and has a locking projection protruding in the direction of the other pipe, and the other pipe In the anti-separation joint consisting of a clamp is coupled to the pressure ring is provided with another locking jaw coupled to the locking jaw and coupled to the locking jaw, and the packing material is installed between the two pipes to prevent the leakage of fluid, The clamp is configured so that two binding members having a wedge on the inner surface for coupling with the other tube are mutually coupled to surround the outer surface of the other tube.

이는 클램프에 구비된 쐐기가 합성수지관의 표면으로 과도하게 삽입되는 것을 방지하는 효과가 있으나, 주철관을 사용하므로 별도의 코팅 작업이 수반되고 클램프를 조이고 해체하는 작업이 불편한 단점이 있다.This has the effect of preventing the wedge provided in the clamp to be excessively inserted into the surface of the synthetic resin tube, but the use of cast iron pipe is accompanied by a separate coating work and has the disadvantage of inconvenient to tighten and dismantle the clamp.
