본 고안은 주로 상수도관으로 이용되는 합성수지제 관체를 연결하는 연결 장치에 관한 것으로 통상적으로 실시되고 있는 플렌지 부분의 연결 장치를 보다 진보시켜서 연결 부분의 견고성을 향상시키는데 그 목적이 있는 것이다.The present invention mainly relates to a connecting device for connecting a synthetic resin pipe used as a water supply pipe, and the purpose of improving the robustness of the connecting portion by improving the connection device of the flange portion which is commonly practiced.

종래에도 여러 가지 구조의 관체 연결 장치가 알려지고 있으나 이들은 거의가 관체의 양단부에 형성된 플렌지 자체에 볼트공을 천공하여 대접된 양쪽 플렌지로 볼트를 관통시켜 너트를 나착시킨 것으로 외력에 의해 볼트와 너트가 나해되어 누수를 초래하는 등의 문제점을 발생시켰던 것이다.Conventionally, pipe connecting devices of various structures have been known, but most of them are made by drilling bolts through flanges formed on both ends of the pipes and penetrating the nuts through both flanges welded to each other so that the nuts and bolts are driven by external force. The problem was caused by leaking and causing leakage.

본 고안은 상기와 같은 제반 문제점을 해결하기 위하여 별도의 플렌지 커버를 이용하여 플렌지 커버 자체에 볼트공을 천공시켜 커버로 볼트가 관통되도록 한 다음 너트로 조여줌으로써 커버가 플렌지를 압지시키는 공지의 장치에 있어서 커버의 사이에 격판을 설치시켜 커버 체결시 볼트와 너트의 체결성을 향상시켜 용이하게 나해되지 못하도록 한 것으로써 도면에 의거 설명하면 다음과 같다.In order to solve the above problems, the present invention uses a separate flange cover to perforate a bolt hole in the flange cover itself so that the bolt penetrates into the cover, and then tightens the nut to a known device that presses the flange. In this case, the diaphragm is installed between the covers to improve the fastening properties of the bolts and nuts when the cover is fastened so as not to be easily broken.

관체(1)의 양단부에 플렌지(3)이 형성된 단관(2)을 열융착 접합시키고 단관(2)의 플렌지(3) 사이에 팩킹(4)을 넣어 대립되도록 하여, 대접된 플렌지(3)의 외주면과 측벽면이 감싸지도록 담면 ㄱ자형으로 되고 다수의 볼트공(6), (6')가 천공된 4개의 반원형 커버(5), (5')로 씌우고 각 커버(5)의 대접되는 전후면 사이에는 양단부에 볼트공(8)이 천공된 격판(7)을 삽지하여 볼트(9)가 일측커버(5)의 외측 볼트공(6)과 격판(7)의 볼트공(8) 및 타측커버(5')의 외측 볼트공(6')로 관통되게 한 다음 너트(10)을 나착함으로서 격판(7)이 끼워지지 않은 커버(5), (5') 사이에는 공간(11)이 생기도록한 것이다.The end pipes 2 with the flanges 3 formed on both ends of the tube body 1 are heat-sealed and the packings 4 are inserted between the flanges 3 of the end pipes 2 so as to be opposed to each other. The outer circumferential surface and the side wall surface are surrounded by four semi-circular covers (5) and (5 '), which are `` A' 'shaped and covered with a plurality of bolt holes (6) and (6'), and are covered before and after each cover (5). Between the surfaces, a diaphragm 7 having bolt holes 8 perforated is inserted between both ends thereof, so that the bolt 9 is provided with an outer bolt hole 6 of one cover 5 and a bolt hole 8 of the diaphragm 7 and the other side. By passing through the outer bolt hole 6 'of the cover 5' and then screwing on the nut 10, a space 11 is formed between the covers 5 and 5 'where the diaphragm 7 is not fitted. To make it happen.

이와같이 된 본 고안 작용 효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above is as follows.

단면 ㄱ자형의 커버(5), (5')를 플랜지(3)의 양쪽에 씌워주므로 커버(5), (5')에 의하여 플랜지(3)이 완전하게 보호되며, 플렌지(3)과는 관계없이 커버(5), (5')에 볼트공(6), (6')가 천공돼 있어서 볼트(9)가 커버(5), (5')만을 관통하게 되며, 커버(5), (5')가 서로 맞닿은 사이에는 격판(7)을 끼워 넣어서 격판(7)의 볼트공(8)으로 볼트(9)가 통과되어 나착됨으로 커버(5), (5')가 서로 플렌지(3)에서 이탈되지 않는다.Covers (5) and (5 ') in cross-section cover both sides of flange (3) so that flange (3) is completely protected by covers (5) and (5'), and with flange (3) Regardless, the bolt holes 6 and 6 'are drilled in the covers 5 and 5' so that the bolt 9 penetrates only the covers 5 and 5 ', and the cover 5, When the 5 'is in contact with each other, the diaphragm 7 is sandwiched and the bolt 9 passes through the bolt hole 8 of the diaphragm 7 so that the covers 5 and 5' are flanged to each other. ) Does not deviate.

그리고, 볼트(9)와 너트(10)를 강하게 조이더라도 플렌지(3)이 파손되는 폐단이 없게 되며, 격판(7)에 의하여 생긴 커버(5), (5') 사이의 공간(7) 때문에 커버(5), (5')가 탄력이 생기게 되어 나착된 너트(10)이 볼트(9)에 서 나해되는 폐단이 없게 되는 것이다.In addition, even if the bolt 9 and the nut 10 are tightly tightened, there is no closed end of the flange 3 and the space 7 between the covers 5 and 5 'caused by the diaphragm 7 is caused. The covers 5 and 5 'are elastic so that the screwed nut 10 has no closed end to the bolt 9.

이상과 같이 본 고안은 플렌지를 이용하여 관체의 연결부분을 보다 안전하고 효과적으로 연결시킴으로서 관체의 사용 기간을 연장시킬 수가 있으며, 누수등의 문제점을 해결할 수가 있게 되는 것이다.As described above, the present invention can extend the service life of the pipe by connecting the connection part of the pipe more safely and effectively by using a flange, so that problems such as leakage can be solved.
