Claims

[Scope of utility model registration request]

A water-stop band comprising a ring-shaped band body whose center part bulges inward, and at least two rows of packing attached to the outer periphery of both ends of the band body, with swelling rubber disposed between the packings; a pair of metal lining bands that are ring-shaped and whose diameter can be expanded by cutting one part and enlarging the cut part;
It consists of a spacer that is inserted between the cut parts of the lining band, and after a water stop band is attached to the inner circumferential surface of the joint part of the pipe, a metal lining band is loosely fitted to the inner circumferential surface of both ends of the water stop band. A pipe joint structure characterized in that a water stop band is attached to the inner surface of a joint part of a pipe through packing and swelling rubber by enlarging cut parts of the band and inserting spacers therein.
