Referring to FIG. 2 , a plurality of structures 100 are connected to pressurize the outer surface of the pipe 10, and are configured to substantially come into contact with the outer surface of the pipe 10. The position of the clamp 1000 is fixed and coupled by applying force to the outer surface of the pipe 10 by receiving force from the fastening bolt 400 of the fastening part. Ideally, the inner curvature of the structure 100 and the outer curvature of the pipe 10 are the same. The structure 100 is generally formed of metal, and the material forming the structure 100 is deformable as required.

The hinge 110 is formed at both ends of the structure 100, and the hinge 110 is coupled to a connecting member 500 such as a fastening part 300 and a link 200 so that the plurality of structures 100 are connected. Hinges 110 are formed at both ends of the structure 100, and are formed on the outer surface forming the outer diameter of the structure 100 so as not to come into contact with the outer surface of the pipe 10. The hinge 110 is formed on the outer surface to prevent the hinge 110 and the pipe 10 from being damaged by pressure. The structure 100 and the connecting member 500 combined with the hinge 110 are rotated based on the central axis of the hinge 110 .

When the fastening part 300 is not coupled to the hinge 110, the link 200 is coupled and connected to the adjacent structure 100. Unlike the fastening part 300 connected by the fastening bolt 400, the link 200 always connects adjacent structures 100, so the storage and management of the clamp 1000 is easy. The number of fastening parts 300 and the number of links 200 can be easily changed by an operator, and the sum of the number of fastening parts 300 and the number of links 200 is a structure constituting the circular clamp 1000 ( 100) is determined by the number of

Rotation of the fastening bolt 400 presses the main body 310 from the outside so that the inclined surfaces 312 on both sides formed on the lower side of the main body 310 are moved so as to approach each other. As the inclined surfaces 312 on both sides of the main body 310 come closer, the structure 100 connected to the main body 310 through the hinge 110 applies force to the outer surface of the pipe 10.

At this time, the main body 310 is rotated by the connected hinge 110, and the structure 100 receives force and pressurizes the pipe 10 so that the main body 310 is gathered around the action point formed at the upper end of the contact between the main bodies 310. As the structure 100 moves in the outer diameter direction of the pipe 10 by the fastening part 300, the structure 100 uniformly pressurizes the outer surface of the pipe 10.
