Piping structure and connection member used in the piping structure

摘要

PROBLEM TO BE SOLVED: To provide a piping structure capable of coping with ground displacement, and a joint for use in the piping structure.SOLUTION: A joint 10A for a piping structure 1A includes a universal part 20, a flexible part 30, and a retainer 40. When ground is displaced by earthquakes and the like, the flexible part 30 is bent and displaced with respect to a branch pipe 90, and the universal part 20 and the retainer part 40 are turned to suppress stress concentration in such a manner as to interlock with the flexible part 30. Thus, the joint exerts the excellent effect of being capable of restraining piping from being broken due to ground displacement.SELECTED DRAWING: Figure 3
