SHOCK ABSORBER FOR STEEL FRAMED STRUCTURE

摘要

PROBLEM TO BE SOLVED: To make a gap between a steel framed structure and another structure narrow by providing a rail having stoppers at both ends on the steel framed structure, then mounting a shock absorber body on the rail, and restraining the movement of the shock absorber body on the rail by a beam extended from another structure. ;SOLUTION: In case displacement is generated to a steel framed structure due to an earthquake or the like and a rail 1 is going to get near the building side in association with oscillation of the steel framed structure, a shock absorber body 2 slides to the opposite side and comes in contact with a stopper 4 on the side far from the building. Further when the displacement of the steel framed structure becomes large, the shock absorber body 2 and a beam 3 come in contact with each other, and the shock absorber body 2 is pressed to the stopper 4 on the side far from the building. Its impact and the oscillation of the steel framed structure are absorbed by an elastic body 6 and a damper 7. In case the steel framed structure is alienated from the building, on the other hand, the shock absorber body 2 comes in contact with the stopper 4 on the building side, and the impact and the oscillation of the steel framed structure are absorbed by the elastic body 6 and damper 7.;COPYRIGHT: (C)1998,JPO
