BASE-ISOLATION STRUCTURE

Title:

BASE-ISOLATION STRUCTURE

Document Type and Number:

Japanese Patent JP2006002559

Kind Code:

A

Abstract:

To provide a base-isolation structure which can secure stable operations by eliminating the risk of exceeding a required allowable limit of vibration even on the occurrence of microvibrations in normal situations, and which enables the effective base-isolation of a structure with arranged anti-vibration equipment, such as a semiconductor manufacturing plant, by exerting a base-isolation effect in an earthquake so as to prevent the occurrence of heavy damage.

A base-isolating device 4, which uses a rigid sliding bearing with such vertical and horizontal rigidity that the microvibrations transmitted to the structure 1 falls short of the allowable limit of vibration, caused by the degree of the anti-vibration of the equipment and the like, is arranged between the structure 1, wherein the equipment and the like apt to be easily damaged by the microvibrations are arranged, and a foundation 3 of the structure 1.
