絶縁継手構造
Document Type and Number:
Japanese Patent JP7072485
Kind Code:
B2
Abstract:
To provide an insulation joint structure capable of maintaining an insulation function between different types of metal materials even when an unexpected external force occurs due to an earthquake, uneven settlement and the like.SOLUTION: An insertion port pipe part 3 has a flange part 3b formed integrally with an insertion port part 3a and extending in the outer diameter direction. A push ring 5 is interposed between a flange part 2b of a receiving port pipe part 2 and the flange part 3b of the insertion port pipe part 3 in an insulated state, and a back surface 5d of the push ring 5 is supported by the flange part 3b of the insertion port pipe part 3. A fastening member 6 is stretched between the flange part 2b of the receiving port pipe part 2 and the flange part 3b of the insertion port pipe part 3, and is inserted in an insulated state.SELECTED DRAWING: Figure 5
