Japanese Patent JP2018131317
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a seismic isolation and vibration control system of a rack warehouse capable of reducing acceleration due to earthquake all over the rack warehouse in a height direction and capable of reducing acceleration regardless of characteristics of input earthquake wave.SOLUTION: The system comprises a vibration control device 2 provided to an uppermost part of a rack structure body 12 for acting as a TMD, and a seismic isolation device 3 provided between a floor surface (installation surface) 15 of a rack warehouse 13 and the rack structure body 12. The seismic isolation device 3 comprises: a lower guide part which is provided to an upper part of the floor surface 15 and has a lower slide surface protruding downward along an X direction and inclining in a V-shape; an upper guide part which is provided to a bottom part of the rack structure body 12 and has an upper slide surface protruding upward along a Y direction and inclining in a reverse V-shape; and a slider which is arranged between the lower slide surface and the upper slide surface, capable of relatively displacing in the X direction to the lower guide part along the lower slide surface, and capable of relatively displacing in the Y direction to the upper guide part along the upper slide surface.SELECTED DRAWING: Figure 1
