<p>PROBLEM TO BE SOLVED: To provide high aseismatic property and prevent detachment, leakage, and the like at a pipe connection part by providing the end parts of adjacent pipes with a plurality of fitting base parts, and connecting the fitting base parts of each pipe end part through a connector expandable in a parallel direction to pipe axes and having a buffer body that can absorb extending force. SOLUTION: In order to prevent detachment at a connection part caused by mutual dislocation of pipes, a plurality of fitting base parts 13 are provided at the end parts of the adjacent pipes 11, 12 and a connector 20 is fitted to the pipes 11, 12 using these fitting base parts 13. This connector 20 is constituted by expandably combining a movable body 21 arranged on one fitting base part side and a movable body 22 arranged on the other fitting base part side and building in a buffer body 23 formed of a coil spring so as to be able to absorb external force at the time of the external force acting in the separating direction of movable bodies 21, 22. The end parts of the movable bodies 21, 22 are fitted by joint members 30 formed of orthogonal shafts 31, 32 and bearing bodies 33, 34 so as to have hinged joint structure rotatable around the mutually orthogonal shafts.</p> |
