Title:
VIBRATION CONTROL, SEISMIC ISOLATION ROTATION CONTROL DEVICE AND MEMBERS
Document Type and Number:
Japanese Patent JP2019070244
Kind Code:
A
Abstract:
To provide a vibration control, seismic isolation rotation control device member to be used for suppressing a movement of a member due to an earthquake rotation motion so that a structure is simple and support construction members can be jointed and diversified although it is effective for earthquake motion control at the time of earthquake disaster.SOLUTION: In a vibration control, seismic isolation rotation control device member, a cylindrical outer case 17 with a cavity and an inner case 7 with a cavity 14 in which a plurality of springs 13A arranged for return, and a primary earthquake motion suppressing part with a large spring 18 are provided. A second earthquake rotation suppressing part in which a plurality of spring 11 are arranged in a cavity 8 between the inner case 7 and a rotation suppression main shaft core part 2A and above and below the cavity 8, and upper and lower center shaft part spiral springs 9-10 are also provided. A sensor 11A is provided in the middle, and a column replacement construction 1A can be performed on an upper part of the inner case 7.SELECTED DRAWING: Figure 1
