The present invention relates to a clamp tightening device for tightening the clamp for fixing the pipe of the ceiling, and more particularly by inserting a bolt between the protruding rod immediately after pinching the plate-shaped fixing member such as a clamp using a head. It relates to a clamp tightening device to facilitate bolting operation.

배관이란 관을 밸브, 관이음 등을 이용, 접속하여 배치하는 것으로, 관은 모든 동력 장치나 액체, 기체의 수송 및 이동에 필요하며, 배관이 설치되는 장소, 용도, 유체 등에 적합한 배관을 설치하도록 이루어진다. Piping refers to the arrangement of pipes using valves, pipe joints, etc., which are necessary for the transportation and movement of all power devices, liquids, and gases. Is done.

배관을 해당하는 위치에 안정적으로 설치하기 위해서는 여러 클램프를 사용하여 배관을 해당 위치에 고정하여 설치하고 있다. 더욱 상세하게 설명하면, 배관을 설치하고자 하는 위치에 배관을 고정하기 위한 구조물이 형성되고, 그 구조물에 배관을 고정하는 방식으로 시공이 이루어지고 있다.In order to install the pipe stably in the corresponding position, the pipe is fixed in the corresponding position using several clamps. In more detail, a structure for fixing the pipe at the position where the pipe is to be installed is formed, and construction is performed in such a manner as to fix the pipe to the structure.

도 1은 일반적으로 구조물에 배관을 고정하기 위해 사용되는 클램프(1)의 사시도이고 도 2는 클램프가 결합되는 구조물의 사시도이다. 도 1에 도시된 바와 같이, 클램프(1)는 금속 재질의 플레이트 일측에 볼트가 끼워지는 홈을 가지는 형태이며, 도 2에 도시된 바와 같이, 클램프(1)의 타측을 구조물(2)에 결합하여 사용하고, 클램프 사이에 배관(3)을 배치하여 클램프(1)를 오므리고 클램프(1)의 홈에 볼트를 끼워 넣어 볼팅처리함으로써 배관을 설치하고 있다. 1 is a perspective view of a clamp 1 generally used to secure a pipe to a structure and FIG. 2 is a perspective view of a structure to which the clamp is coupled. As shown in FIG. 1, the clamp 1 has a groove in which a bolt is fitted to one side of a metal plate, and as shown in FIG. 2, the other side of the clamp 1 is coupled to the structure 2. The pipe 3 is provided between the clamps, the clamp 1 is closed, the bolt is inserted into the groove of the clamp 1, and bolting is performed.

이때, 일반적으로 공사현장에서는 클램프(1)를 오므리기 위해 니퍼, 펜치 등의 장비를 이용하고 있는데, 상기의 장비를 이용하는 경우 클램프(1)의 홈이 장비에 의해 가려지기 때문에 클램프를 오므린 뒤 장비를 치우고 볼트를 끼워 넣어 고정하도록, 즉 클램프(1)를 오므리는 작업을 한 뒤 장비를 치우는 작업을 실시하고 그 뒤에 볼팅 작업을 실시하고 있어, 배관공사에 많은 시간이 소요되는 문제점이 있다. In this case, in general, construction sites are using equipment such as nippers, pliers, etc. to retract the clamp (1), in the case of using the above equipment because the groove of the clamp (1) is covered by the equipment after closing the clamp To remove the equipment and insert the bolts to fix, that is, after the work to retract the clamp (1) is carried out to remove the equipment and then bolting work, there is a problem that takes a lot of time in the plumbing work.

특히, 천장에 배관을 설치하는 경우, 클램프(1)를 오므린 뒤 오므리던 장비를 치우면 클램프(1) 사이에 놓인 배관(3)이 아래로 빠질 위험이 있으므로, 볼팅작업을 위해서는 장비를 치운 뒤에 한 손으로 클램프(1)를 잡고 볼팅작업을 실시하여 사용자에게 많은 불편함을 야기하였으며 배관공사에 많은 시간이 소요되는 문제점이 있었다. In particular, in the case of installing the pipe on the ceiling, when the clamping device is removed and then the equipment is removed, there is a risk that the pipe 3 placed between the clamps 1 may fall down. Holding the clamp (1) with one hand to perform a bolting operation caused a lot of inconvenience to the user and there was a problem that takes a lot of time in the plumbing work.

또한 클램프(1)에 힘을 가하여 오므린 뒤, 클램프(1)에 가하던 힘을 제거하는 경우, 클램프(1)가 원래의 형태로 되돌아가는, 즉 클램프(1)가 다시 약간 벌어지는 경우가 발생할 수 있는데, 클램프(1)의 벌어진 거리가 볼트의 몸통 길이보다 긴 경우 다시 장비를 이용하여 클램프(1)를 오므리고 장비를 치운 뒤 볼팅작업을 실시하는, 즉 여러 동작을 반복적으로 실시해야 하는 문제점이 있다.In addition, when the force applied to the clamp 1 is retracted and then the force applied to the clamp 1 is removed, the clamp 1 may return to its original shape, that is, the clamp 1 may be slightly opened again. If the distance of the clamp 1 is longer than the length of the body of the bolt, there is a problem that the bolting operation is carried out after the clamp 1 is removed by using the equipment and the equipment is removed, that is, the operation must be repeatedly performed. have.
