PRELIMINARY SHEAR DEFORMATION HOLDING MEMBER, HOLDING DEVICE AND HOLDING METHOD FOR RUBBER BEARING

摘要

PROBLEM TO BE SOLVED: To provide such structure as removal work of a rubber bearing shear deformation holding member is not required after the concrete of an upper structure is solidified. SOLUTION: A rubber bearing shear deformation holding member is equipped with an adjustor 1 constituted of first and second members 2 and 3 connected in a contractible and movable manner by having specific compressive force. One end of the adjustor 1 is interlocked with a reaction wall 21 of a lower metal plate 12 mounted to the lower part of a rubber bearing body 14, and the other end of the adjustor 1 is interlocked with an interlock section 22 of an upper metal plate mounted to the upper part of the rubber bearing boy 14 to be preliminarily sheared and deformed.
