Description

Coupling band for pipe joint

본 고안은 관이음용 커플링밴드에 관한 것으로, 더욱 상세하게는 관이음시 누수예방과 관의 이음부가 벌어지거나 분리되는 현상을 예방하여 매우 견고한 조립 및 이음이 이루어지게 하기 위한 것이다.The present invention relates to a coupling band for pipe joints, and more particularly, to prevent leakage of the pipe joints and to prevent the phenomenon of opening or separating of the pipe joints to make a very solid assembly and joints.

주지된 바와 같이 관이음용 커플링밴드는 두개의 관을 맞대어 이을때 누수와 관의 탈리를 예방하기 위해 사용하는 것으로, 통상 볼트결합부를 가진 금속판재를 밴딩시켜서 된 본체와 누수를 예방하기 위해 사용하는 판형의 스펀지로 된 패킹부재로 되어 있다.As is well known, the coupling band for pipe joint is used to prevent leakage and desorption of the pipe when the two pipes are joined together, and is usually used to prevent the main body and the leak by banding a metal plate having a bolted joint. It is made of a plate-shaped sponge packing member.

그러나 전술한 종래의 커플링밴드는 다음과 같은 문제점으로 인하여 신뢰성이 크게 떨어지는 폐단이 따른다.However, the above-described conventional coupling band has a closed end that is greatly reduced in reliability due to the following problems.

즉 종래 커플링밴드는 본체가 단순히 금속판재를 밴딩시켜 놓은 것이고, 패킹부재 역시 스펀지 등을 말아 사용하는 구성이기 때문에 관이음시 길이방향으로 압력이 작용하면 관체가 쉽게 빠지는 현상이 발생하게 되고, 이에 따라 누수가 발생되어 하수관 등의 경우는 토양을 오염시키는 등의 폐단이 따랐으며, 더불어 두개의 관체를 맞이음시 작업이 번거로우면서도 정확한 조립이 어려운 폐단이 따랐던 것이다.That is, in the conventional coupling band, the main body simply bands a metal plate, and since the packing member also uses a sponge or the like, the pressure is applied in the longitudinal direction when the pipe is jointed, and thus, the tube is easily removed. As a result, leakage occurred and sewage pipes were polluted with soil, and when two pipes were met, the work was cumbersome and difficult to assemble correctly.

다시말하면, 종래의 커플링밴드는 맞대어진 두개의 관체 이음부 표면에 단순히 씌워 결합시킨 구성이기 때문에 조립시에 관체에 작용하는 인장력에 의한 분리현상과 더불어 땅속에 매설한뒤 토압 및 하중에 의해서도 분리되는 현상이 발생되어 견고하게 조립시공하여 매설하였더라도 오래가지 않아 이음부가 서로 벌어져 누수가 발생되기 때문에 신뢰성이 크게 떨어졌다는 것이다.In other words, the conventional coupling band is composed by simply covering and joining two mating pipe joint surfaces together, so that the coupling band is separated from the earth by the tensile force acting on the pipe during assembly, and then buried in the ground and separated by earth pressure and load. Even if the phenomenon occurs, even if it is firmly assembled and buried, it does not last long, so that the joints are separated from each other and water leaks, and thus the reliability is greatly reduced.

따라서 본 고안은 전술한 종래 커플링밴드에 대한 제반문제점을 감안하여 안출된 것으로 특히 커플링밴드를 구성하는 본체는 양측부를 가압하여 내측면에 걸림돌출부가 형성되게 끔 프레스성형하고, 밀폐용패킹부재는 고무재질 또는 연질합성수지재질로 형성하되, 본체에 형성된 걸림돌부가 끼워지도록 표면양측에 걸림요부를, 그리고 내경에는 상기 걸림요부와 반대로 걸림돌부가 형성되게 하며, 더불어 상기 패킹부재를 원통형 관체 형상으로 형성하고, 관체 양끝단부위에는 걸림요부를 형성하여 두개의 관체를 맞이음시 패킹부재에의해 정확하게 연결조립되면서 본체를 볼트와 너트를 이용하여 조임시 견고한 조립이 이루어지게 하여 외부에서 작용하는 압력이나 하중에 의해 벌어지거나 분해되는 경우를 예방 할 수 있게 함으로써, 누수예방 및 견고한 조립효과 등을 기대 할 수 있게 하려는데 그 목적이 있는 것이다.Therefore, the present invention has been devised in view of the above-mentioned problems with the conventional coupling band, and in particular, the main body constituting the coupling band is press-molded so that a locking protrusion is formed on the inner side by pressing both sides, and the sealing member is sealed. Is formed of a rubber material or a soft synthetic resin material, the engaging recess formed on both sides of the surface so that the engaging projection formed on the main body, and the inner diameter to form a locking projection opposite to the engaging recess, and the packing member is formed into a cylindrical tubular shape On both ends of the pipe, a locking recess is formed so that when the two pipes are fitted together, they are precisely assembled and assembled by the packing member, and when the body is tightened using bolts and nuts, it is firmly assembled to meet the external pressure or load. To prevent leakage or breakdown by The purpose is to make it possible to expect a solid assembly effect.
