Seismic isolation device equipped with a damping mechanism of the damper format.

摘要

Method of fixing the seismic isolation device having a bearing mechanism by rollers that are orthogonal to overlap to [challenge] up and down, the orthogonal angle of the roller, and structures so shakes when the damping force excessive with the damping mechanism for seismic energy , I create a damping mechanism that has a damping force control suppression function corresponding to seismic energy. In order to maintain the orthogonality angle [SOLUTION] rollers, fixed orthogonal angle by mounting the quadrature portion of the roller, the restraint material remembering a slight gap that allows the rolling of the roller, steel linear cylindrical By the damping force energy absorption when deformed continuously by a horizontal force winding the timber, to vary the axial cross-sectional area of ​​the steel linear, controls the amount of energy absorption, and energy absorption also block the horizontal force suppresses the amplitude range of the small seismic energy absorption of steel linear back away from, was able to suppress the control damping force and damping mechanism of the damper format.
