Description

Elbow clamp {ELBOW CLAMP}

The present invention relates to an elbow clamp installed in a curved section of a pipe.

In general, clamps are used for connection between pipes or connection between pipes and other members in construction works such as building construction, temporary construction, civil engineering, sewage construction, or river construction.

These clamps usually have a support to receive the pipe, a cover and a clamping fitting.

In such a conventional pipe clamp, a tightening tool for coupling the other end of the support and the other end of the cover is composed of a bolt and a nut, and the bolt is provided at the other end of the support, and the nut is screwed to the bolt in a state where the bolt is inserted into the other end of the cover. It is a structure for fixing the support and the cover according to.

In such a screw coupling method, when vibration of the pipe occurs, the screw coupling is easily loosened, and an accident may occur in which gas or liquid inside the pipe is discharged to the outside due to widening of the pipe connection portion.

In addition, existing clamps for pipes are installed in a straight section, and there is a problem in that they cannot be installed in a portion where the traveling direction is changed.

In particular, in the elbow pipe in which the direction of travel is changed to 90 degrees, there is a problem in that vibration is continuously generated by the fluid flowing into the pipe and corrosion occurs frequently.
