減震ユニット及び減震システム
Document Type and Number:
Japanese Patent JP6654905
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a unit and a system capable of realizing earthquake countermeasure by attaining effects of removal and prevention of vibration, and a vibration damping effect by a more simple structure as compared with that of a vibration attenuation structure necessitating a large amount of investment and a long movable distance and additionally as compared with that of an isolation frame constituted by an upper frame, a lower frame, an upper frame moving amount specification part and a vibration absorption body.SOLUTION: There are provided [i] an elastic supporting member for supporting a load of object equipment to be protected and [ii] means for restricting the amount of motion of the elastic supporting member by a narrow clearance, and the [i] and [ii] are stored in one unit to constitute "a pseudo rigid body unit". An upper limit value restriction part and a lower limit value restriction part are provided on a shaft core of the elastic supporting member and the upper limit value restriction part and the lower limit value restriction part are constituted in such a way that they can be adjusted from outside under a state in which the object equipment to be protected is installed therein.SELECTED DRAWING: Figure 1
