Title:
構造物免震不倒基部
Document Type and Number:
Japanese Patent JP3123586
Kind Code:
U
Abstract:
A rocking-type seismic isolation base for protecting structure against earthquake includes a body having a configuration similar to a generally recognized flying saucer. The base serves as a buffer when a structure is horizontally displaced relative to a supporting foundation of the structure, and largely reduces the vertical displacement of the structure. The rocking-type seismic isolation base also allows the displaced structure to automatically return to its original position. The base is provided at a bottom with a space for an anti-slipping lock to mount and freely move therein, so as to prevent the rocking-type base from horizontally slipping in a condition exceeded the designed seismic vibration. The rocking-type base may be cooperatively used with a saucer spring to further mitigate the vertical vibration.
