Seismic Isolation Device of An Architectural Structure

摘要

A seismic isolation device of an architectural structure is provided to absorb vibration created by earthquakes by installing a buffer block covering seismic isolation modules between upper and lower plates. A seismic isolation device of an architectural structure comprises an upper plate(3), a lower plate(5), seismic isolation modules(9,9'), and a buffer block(31). The upper blocks is attached to the top bottom of a support body(10). The lower plate is attached to the bottom top of the support body, and faces the upper plate. The seismic isolations are installed between the upper and lower plates. The seismic isolation modules, which are piled each other crisscross, each include covers(4,4'), bottom plates(6,6'), and a plurality of rollers(7,7'). Guide beams(11,11') are attached to the bottom of the covers. The bottom plates include slide beams(13) installed at lateral protrusions(21). The rollers are in contact with the bottom of the cover and the top of the bottom plate. The buffer block is installed between the upper and lower plates and covers the seismic isolation modules.
