본원발명은 파형강관 연결장치에 관한 것으로, 더욱 상세하게는 상호 인접하 는 2개의 파형강관의 단부를 기밀성이 양호하며 또한 용이하게 에 연결할 수 있도록 하는 파형강관 연결장치에 관한 것이다.The present invention relates to a corrugated steel pipe connecting device, and more particularly, to a corrugated steel pipe connecting device that can be connected to the end of the two corrugated steel pipe adjacent to each other with good airtightness and easily.

일반적으로 파형강관은(Corrugated Steel Pipes)은 토목 분야에서 오수 및 폐수의 배수, 생활 용수 또는 산업용수의 급수, 건축분야에서 중공 거푸집이나 건축용 슈트로서 널리 사용되고 있다. Generally, corrugated steel pipes are widely used in civil engineering as drainage of sewage and wastewater, water supply of domestic or industrial water, and hollow formwork or construction chutes in construction.

최근에는 배수관 건설 시에 인력난과 비용 및 환경 문제에 대한 인식의 증대로 인하여, 기존의 콘크리트재 배관의 대체 자재로 많이 사용되고 있으며, 그리고 높은 외압강도와 구조적 안정성, 내구성, 경제성 및 시공성이 우수한 배관자재로 주목 받고 있다.Recently, due to the increase of manpower and cost and environmental awareness in the construction of drainage pipes, it is widely used as a substitute for existing concrete pipes, and piping materials with high external pressure strength, structural stability, durability, economic efficiency and constructability I am attracting attention.

또한, 파형강관은 하중 및 반력이 관둘레에 균등하게 분포되어 내하력이 커서 수로, 통로,기타 각종 구조물에 사용되며, 경량으로 취급이 용이하므로 조립과 시공이 모두 간단하고 경제적일 뿐만 아니라, 용융아연도금 강판을 사용하기 때문에 부식에 강하고 수명이 긴 장점이 있다.In addition, corrugated steel pipe is used in waterways, passages, and other structures because its load and reaction force are distributed evenly around the pipe, and it is easy to handle due to its light weight. Because of the use of plated steel sheet, it has the advantage of being resistant to corrosion and long life.

이러한 파형강관은 시공될 길이에 따라 여러개의 강관을 길이방향으로 서로 연결하여야 하는데, 상기 강관의 연결을 위하여 견고한 연결장치가 요구된다. 특히 파형강관이 오,폐수 등의 수로 또는 통로로서 사용될 때, 파형강관 연결장치가 가져야 할 가장 중요한 기계적 특성은 연결부의 기밀성이다.These corrugated steel pipes are to be connected to each other in the longitudinal direction according to the length to be constructed, a solid connection device is required for the connection of the steel pipes. Particularly when corrugated steel pipe is used as a channel or passageway for wastewater, wastewater, etc., the most important mechanical property that a corrugated steel pipe connection device should have is the airtightness of the connection part.

이와 같은 요구조건을 만족시키기 위한 파형강관 연결장치의 일례가 한국 실용신안등록 제0220068호에 개시되어 있다. An example of a corrugated steel pipe connecting device for satisfying such a requirement is disclosed in Korean Utility Model Registration No. 0220068.

그러나, 상기한 종래의 파형강관 연결장치는 파형강관의 외주면 형상에 따라 내주면을 제작해야 하기 때문에 제조가 어려운 문제점이 있었다.However, the conventional corrugated steel pipe connection device has a problem that it is difficult to manufacture because the inner peripheral surface should be manufactured according to the outer peripheral surface shape of the corrugated steel pipe.

더욱이, 장시간 사용함에 따라 조임부재(15)가 인장됨에 따라 조임력이 약화되어 상기 플랜지(12) 사이의 밀폐성이 떨어지게 되는 문제점이 있었다.Moreover, as the tightening member 15 is tensioned as it is used for a long time, there is a problem in that the tightening force is weakened and the sealing property between the flanges 12 is inferior.
