Title:
免震用ダンパ
Document Type and Number:
Japanese Patent JP7186388
Kind Code:
B2
Abstract:
To provide a base-isolation damper which can prevent its buckling while securing a stroke length enough to cope with long-period earthquake vibration, generate stable damping force while preventing the breakage of the base-isolation damper and surrounding members of the base-isolation damper, and suppress residual displacement in a base-isolation layer after earthquake.SOLUTION: A base-isolation damper D1 includes a hydraulic damper OD, a structure side mounting deice SB for mounting the hydraulic damper OD on a structure S in a horizontally rotatable manner, and a ground side mounting device GB for mounting the hydraulic damper OD on a ground G in a horizontally rotatable manner, one or both of the structure side mounting device SB and the ground side mounting device GB having resistance members whose expansion/contraction is constrained in one direction and which expand/contract when a load exceeding a predetermined load acts in the expanding/contracting direction, while exerting resisting force to prevent the expansion/contraction, and damper side brackets 18 each connecting one end of the resistance member to the hydraulic damper OD, the resistance member being a friction damper FD or a steel damper.SELECTED DRAWING: Figure 1
