Title:
免震装置、昇降装置および免震ユニット
Document Type and Number:
Japanese Patent JP6437177
Kind Code:
B2
Abstract:
A structure having limited supportable portions has been difficult to isolate from vibration in the direction in which a load is applied. A base isolation apparatus includes a Z-axis base isolation unit 7 for isolating an object from vibration in a vertical direction in which a load is applied, an X-axis base isolation unit 8 for isolating the object from vibration in an X-axis direction in a horizontal plane, and a Y-axis base isolation unit 9 for isolating the object from vibration in a Y-axis direction in the horizontal plane different from the X-axis direction. The base isolation unit includes: a vibration-source connector 19 to be connected with a structure 70 or ground 71; an isolated-object connector 26 to be connected with an object to be isolated from vibration and movable with respect to the vibration-source connector 19 in a direction in which the object is isolated from vibration; a lock device 13 disposed between the isolated-object connector 26 and the vibration-source connector 19 for switching between a state of fixing the isolated-object connector 26 and a state of making it movable; a distance recovery device 14 for generating a force to cause an amount of change in distance to approach zero, depending on the amount of change; and a vibration damper 15 for generating a force in an orientation of hindering the change, depending on the rate of change in distance.
