<p><P>PROBLEM TO BE SOLVED: To provide a joint structure in which bending performance of a joint can be held either in being buried in the ground or in being covered by lining concrete. <P>SOLUTION: This joint structure is for connecting the pipes to each other while holding flexibility. It is opened at both ends, and a pipe connection part 1 to match outer diameter of the pipe to be connected is provided at one end, while a sleeve connection part 2 of larger diameter than outer diameter of the pipe connection part 1 is provided at the other. Elastic joint main bodies A1 and A2 each comprising the pipe connection part 1 and the sleeve connection part 2 connected by a flexible deformation part 3 are disposed to put the sleeve connection parts to face each other. The sleeve connection parts 2 are fixed to a sleeve A3 that is harder than the elastic joint main body by a band. The pipes P1 and P2 are inserted to the pipe connection parts at the elastic joint main bodies. The pipes are closed between their inserted ends, and the pipe connection parts are fastened to the pipes by a fastening band 4. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
