を切り欠いて成形されている。The anti-slip device of the present invention comprises a pair of half-cylindrical cylindrical members (11, 11 '). In the present specification, the term "cylindrical half-shaped member" means that a cylindrical wall is cut off at a small width along a length direction of a cylinder at two circumferential positions as shown in FIGS. (Truncation) means a member obtained by dividing a cylinder in half. In the case of FIG.
The cylindrical wall is cut out on both the inner side and the inlet side of 2 ′), but in the case of FIG. 3, the cylindrical wall is cut off only on the inlet side.

Has a fulcrum at a substantially central portion in the length direction of these members and at an end face in a circumferential direction. As used herein, the term "fulcrum" refers to the principle of leverage, in which the outer wall of only the inner part of the pipe is attached to the inner wall of the pipe by attaching an anti-slip device to the pipe and tightening a pair of pipe ends. , Which widely means a fulcrum at the time of pressing. In the case of FIG. 2, the projections (12, 12 ') serve as fulcrums as they are,
In the case of FIG. 3, the points 13 and 13 'are fulcrums. The fulcrum is naturally formed in the circumferential direction.

5 ') are not shown, but are fastened together using suitable parts, for example bolts. There is no particular limitation on the shape or position of the fastening member, and there is no particular limitation on the method of attaching or fixing the fastening member to the half-cylindrical member. When the tightening member is tightened, the outer wall of only the inner part of the tube of the member is pressed against the inner wall surface of the tube with a large force by the principle of leverage, and the object of fixing the anti-slip device in the tube can be achieved. In the anti-slip device of the present invention, as one embodiment, instead of attaching a fastening member to an end of a cylindrical half-shaped member protruding from the end of the tube, a wire having an appropriate diameter is attached to this end. It is also possible to wind and use this end as it is for tightening.

It is advantageous that the portion protruding from the inner side of the tube 3 or 13 ') is formed integrally with the half-cylindrical member.

The outer wall surfaces of the pair of members including the fulcrum are selected so as to contact the inner wall surface of the tube. Usually, it is sufficient to make the outer diameter of the pair of half-cylindrical members smaller by 1 to 2 mm than the inner diameter of the pipe. However, the anti-slip device of the present invention can also be used by winding a thin, for example, rubber sheet piece around the outer wall surface of only the inner portion of the tube of the half-cylindrical member. In such a case, the outer diameter of the half-cylindrical member at the inner part of the pipe is reduced as much as the thickness of the rubber sheet in such a case. The dimensions such as the length and thickness of the half-cylindrical member can be appropriately selected according to the material and the inner diameter of the pipe.

い。There is no particular limitation on the material of the half-cylindrical member, and the force generated when the pair of pipe-port side ends are tightened together presses the inner part of the pipe against the inner wall of the pipe with a large force. What is converted into a force, that is, a material having a small elasticity, is usually sufficient. However, considering that the water blocking material is exposed to water leakage generated in the pipe for a long time and the humidity in the pipe is high, stainless steel is preferable as the material of the anti-slip device.
