摘要： PROBLEM TO BE SOLVED: To facilitate the work of attaching a stopper to the end part of a connecting pipe by providing stoppers for regulating a maximum relative moving amount between a spherical ring and the connecting pipe in both end parts and a middle part of a pipe having spherical rings to be slid in both ends and providing the middle part stopper to be moved in a pipe axial direction. SOLUTION: For assembling an flexible pipe joint, first a stopper 13 and a pair of spherical rings 2 are fitted in a connecting pipe 8 in sequence. Then, the stopper 13 is moved to the right of a locking piece 12, then slid until the end surface of the cylindrical part 7 side of the left spherical ring 2 is contacted with the locking piece 12, and then the left end part of a connecting pipe 8 is protruded from the spherical ring 2. In this state, a stopper ring 10 is fitted in the annular recessed groove 8a of the end part of the connecting pipe 8 and fixed by a bolt 11. Then, in the same manner, the stopper ring 10 is fixed to the right end part of the connecting pipe 8, then a case 1 is fitted around each spherical ring 2 to be engaged with a press ring 5 and, by engaging the stopper 13 with the locking piece 12 and preventing rotation with a stop screw 17, assembling is completed.

摘要： 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.

摘要： PROBLEM TO BE SOLVED: To height base isolation function of varieties of piping by arranging a bending coupling in such a manner as to be movable on the floor surface, and interposing a flexible pipe between the bending coupling and a vertical pipe to permit the vertical pipe to displace in the horizontal direction of the lateral pipe. SOLUTION: A drain lateral main pipe 10 is piped along the ground G through a flexible pipe 7 and a leg part coupling 9 for a drain vertical pipe 6 vertically piped through a building. The pipe 10 is capable of singly moving in the lateral direction (horizontal direction) for the vertical pipe 6 by deformation of the pipe 7 and the movement of the leg part coupling 9. Even if rolling is generated by an earthquake or the like, the pipe 7 is deformed so that such rolling is absorbed between the vertical pipe 6 and the pipe 10 to prevent damage of a drain path. Accordingly, in addition to mutual vibration absorption of lateral piping, vertical piping path can be let have a vibration absorbing function, so that the base isolation function of the building can be further heightened.

摘要： PROBLEM TO BE SOLVED: To easily form a projected part of an outer periphery of an insertion port of a pipe. SOLUTION: A spacer 23 to arrange first and second rings 21, 22 along the shaft center direction by maintaining a constant distance is interposed between the first and second rings 21, 22 having specified thickness in the diametrical direction. The first and second rings 21, 22 in a state where this spacer 23 is interposed are press fit on an outer periphery of an insertion port 25 of a pipe 24. Thereafter, a ring groove 28 in the circumferential direction is formed by the first ring 21, an outer surface of the insertion port 25 and the second ring 22 by removing the spacer 23 from between the first and second rings 21, 22. Thereafter, the first and second rings 21, 22 and the insertion port 25 are welded by flowing weld metal in the ring groove 28.
