Title:
ACTIVE TYPE SEISMIC ISOLATOR
Document Type and Number:
Japanese Patent JP2018096507
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an active type seismic isolator having an improved structure capable of realizing a seismic isolation performance or the like to be required while a free degree in design of a main body rubber elastic body is being substantially assured at a seismic isolator mount main body and capable of corresponding to a vibration adding force to be required or a stroke and the like while a free design degree of a rubber wall is being assured at the vibration applying means.SOLUTION: This invention comprises a seismic isolator mount main body 12 in which a first fixing member 16 and a second fixing member 18 are connected by a main body rubber elastic body 20 and a pressure control chamber 78 to which pressure medium is filled and a pressure variation by an actuator 84 is applied, and includes vibration adding means 14 where an output member 70 is elastically supported by a rubber wall 50 of the pressure control chamber 78. A first fixing member 16 of the vibration isolator mount main body 12 and the output member 70 of the vibration adding means 14 are integrated and at the same time the second fixing member 18 of the vibration isolator mount main body 12 and the output member 70 of the vibration adding means 14 are applied as an integrated structure and the second fixing member 18 of the vibration isolator mount main body 12 and the pressure control chamber 78 of the vibration adding means 14 are integrally supported.SELECTED DRAWING: Figure 4
