<P>PROBLEM TO BE SOLVED: To provide a pipe coupling device capable of firmly attaching a water stop member to an outer circumferential face of a fluid pipe with sufficient force. <P>SOLUTION: The pipe coupling device 1 water-tightly connects a socket pipe 3 and a fluid pipe 2 by pressing a wedge 6 by pressing means 3b, 4, 8 to reduce an inner diameter dimension of a ring body 5 in accordance with an outer diameter of the fluid pipe 2. Each wedge 6 linearly moves toward a pipe axis C by being pressed by the pressing means 3b, 4, 8. The force of the pressing means 3b, 4, 8 to move the wedge 6 to the pipe axis C is controlled to be sufficient to firmly attach a water stop member 7 to the outer circumferential face 2a of the fluid pipe. <P>COPYRIGHT: (C)2012,JPO&INPIT |
