<p>PROBLEM TO BE SOLVED: To absorb a difference of displacement of a pipeline member to be generated between fixed positions by earthquake without using a special displacement absorbing joint by bending the pipeline member into a circle between both the fixed positions. SOLUTION: A coolant pipeline 4 is bent into a circle on a slide plate 8a positioned between a fixed position A and a fixed position C. A circular shape holding member 10 such as a hard vinyl chloride hose is fitted on an upper half part of a circular part 4A so as to prevent the bend and so as to give the restoring force. With this pipeline structure, even in the case where an earthquake is generated, a difference of vibration is generated between the fixed position A and the fixed position C, and a difference of displacement of the coolant pipeline 4 is generated between the fixed position A and the fixed position C. Never the leso, the difference of displacement between them can be absorbed by enlarging or shrinking the diameter of the circular part 4A. Breakdown of the coolant pipeline 4 is thereby prevented.</p> |
