By inserting the pipe fastening cap 30, the semi-circular protrusion wheel 21 of the joint 20a of the pipe 20 can flow from side to side within the interval between the X-type washer 2 and the X-shaped support ring 32. To form a gap (m)
The upper and lower thicknesses of the clamp are inserted into the upper and lower circumferences of the tip flange 11 of the socket 10 of the enlarged tip portion 10a and the ring-shaped plate 31 of the pipe fastening cap 30. Circularly concave and convex surfaces 11b are formed on the inward side of the tip flange 11 of the socket 10 and the enlarged tip portion 10a and the outward side of the ring-shaped plate 31 of the pipe fastening cap 30, respectively. ) And 31b respectively.
Figure 112013017008453-pat00019
A plurality of rectangular triangular protrusions 41a inclined toward the tip end are formed on the inner side surfaces of both elastic surfaces 41 of the mold clamp 40 in the longitudinal direction to connect the joints 20a of the pipe 20 to the socket 10 when the pipe is connected. Inserted into the inner periphery of each enlarged tip portion 10a, the ring-shaped support ring 32 replaces the ring-shaped plate 31 of the pipe fastening cap 30 with a gap between the pin-type washer 2 and a predetermined buffer space m. ) And the front flange 11 of the enlarged tip portion 10a of the socket 10 are coupled to each other such that the upper and lower recessed ends 11a and 31a coincide with each other.
Figure 112013017008453-pat00013
As a clamp 40, the upper flange 11 and the ring-shaped plate 31 are joined to each other, and the seizure ends 11a and 31a of the lower part are inserted into the gap between each other for easy seismic coupling. Pipe Joint Coupling 삭제delete
