Abstract:
PROBLEM TO BE SOLVED: To provide a friction damper capable of being inexpensively manufactured into a simple construction requiring little maintenance, and capable of being easily installed. SOLUTION: In the friction damper 1, a rod member 2 whose outer diameter is changed to be larger as tending from the center toward both ends is arranged on one relatively displaceable structure part side, and a friction member 6 movably fitted into the rod member 2 is arranged on the other structure part side. On the friction member 6, an elastic member 8 split into a plurality of parts in the circumferential direction and a sliding member 9 split into a plurality of parts in the circumferential direction to form the outer peripheral face and the sliding face of the rod member 2 are arranged in a tubular outer frame.

Abstract:
PROBLEM TO BE SOLVED: To provide an on-site vulcanization repairing method for a rubber bearing for a structure in which an on-site operation is easily performed by a simple structure and a repairing working time can be shortened, and an electromagnetic induction heating apparatus for on-site vulcanization repair for the rubber bearing for the structure. SOLUTION: The on-site vulcanization repairing method for the rubber bearing for the structure is characterized in that a deteriorated rubber layer of the rubber bearing for the existing structure is cut and removed to coat a repaired part with an unvulcanized rubber protective material to introduce a magnetic field generated by the electromagnetic induction heating apparatus arranged near the rubber bearing for the structure to a metal plate brought into contact with the repaired part through a magnetic circuit means, and to generate joule heat in the metal plate by the magnetic field to vulcanize and repair the unvulcanized rubber protective material.
