により簡単に外れ易い欠点がある。 This type of liquid transfer pipe is mainly made of concrete, so there is a risk of cracking if water leaks at the joint. Since the pipes are buried in the ground, sealing the leaks requires a laborious excavation work from the outside, requiring high construction costs, and sometimes leaving areas that cannot be repaired. On the other hand, Utsukai 54-
A known technique is disclosed in Japanese Patent No. 138117, which discloses a technique of jacking up the ends of a divided presser metal fitting. However, the ends of the divided fittings are only butted against each other, but are not firmly fixed, and only a small piece called a filler piece is fitted into the gap forcibly opened with jacks, and the pipes to be connected are connected to each other. It has the disadvantage that it easily comes off due to slight fluctuations.

作用を良くしてある。 That is, the present invention is a thick annular band body 1 made of rubber.
A pair of semi-annular tourniquets 2a and 2b are applied to the inner surfaces of both ends of the annular band body 1 and are connected to each other in a state in which the annular band body 1 is tightened outward at both ends.
and a metal reinforcing plate 3 that closes the gap between the pair of liquid transfer tubes A 1 and A 2 connected on the circumferential surface of the band body 1, and the pair of semi-annular tourniquets 2a, 2.
In b, the ends are overlapped with each other, and female threads 5 are bored in several places in the circumferential direction of the lower end 2e.
The hook ring 8 of the jack 6 is provided on the inner surface of the upper end 2f, and the stepped portion 9 of the plate-shaped connecting piece 10 is engaged with the upper end 2f, and the hook ring 8 is attached to the hook 7.
Each tourniquet 2a,
2b is pressed into contact with the inner surface of the band body 1 to prevent leakage of a liquid transfer pipe. In the illustrated embodiment, a pair of semi-circular tourniquets 2 are formed from metal plates.
a and 2b are formed so that one end becomes gradually thinner, two rows of female threads 5 are drilled in several places in the thin layer part 2c, and a non-thin hole is formed at the other end of the tourniquet corresponding to the rear of the five rows of female threads. The layer part 2d has a hook ring 8 fixed to the inner surface thereof, which is engaged with the catch hook 7 of the jack 6, and is also provided with a connecting piece 10 having a stepped part 9. 2b to the inner surface of the band 1, as shown in FIG.
2b are stacked on the thin layer portion 2c and non-thin layer portion 2d using the stepped portion 9 of the connecting piece 10, and the screw 12 is screwed into the female thread 5 through the long hole 11 formed in the connecting piece 10 to secure both ends. After the bands are connected and fixed, the jack 6 is removed. In addition, 13 in the figure shows a band receiving protrusion provided on the inner surface of the annular band, and the watertight protrusion 4 is provided at both ends and is formed into a tip edge shape 4a to provide a watertight effect for crimping on a transfer pipe that is not a perfect circle. It has been improved.

るので、がたも生じない。 As described above, the present invention securely prevents water leakage by tightening the band body 1 from the inside and sealing with the band body 1, and the joint portion of both liquid transfer pipes A 1 and A 2 is well protected against high pressure by the metal reinforcing plate 3. It is durable and can reliably stop water leaks. In addition, since the tourniquets 2a and 2b that tighten the band body 1 are divided into semi-circular shapes, it is easy to carry them into the narrow liquid transfer pipes A1 and A2 , and the work is easy and the tightening action is even stronger. The connecting piece 1 has the effect of
Since connecting piece 1 is plate-shaped, the protrusion into the transfer pipes is small and hardly impedes the flow of liquid.
0 can be located anywhere within the pipe.
Particularly, according to the present invention, when connecting the semi-annular tourniquets 2a and 2b, the connecting piece 10 whose ends overlap each other and is locked to the upper end 2f is connected to the screw 1.
2, it is tightened to the female thread 5 of the lower end 2e, so it has a feature that it does not easily come off even if a considerable external force is applied. as well as mutually overlapping ends 2e,
2f is expanded by the jacks 6, and at the same time female screws 5 are provided in several places in the circumferential direction, so that adjustment can be made appropriately and it can be firmly tightened as described above, so that no rattling occurs.
