VERTICAL RIGIDITY MECHANISM ADJUSTING VERTICAL RIGIDITY OF LAMINATED RUBBER BASE ISOLATION DEVICE, LAMINATED RUBBER BASE ISOLATION DEVICE, AND BASE ISOLATION BUILDING
PROBLEM TO BE SOLVED: To prevent bending deformation from occurring in a region where deformation in a horizontal direction of rubber, included in a vertical rigidity adjustment mechanism of a laminated rubber base isolation device, is constrained, and set vertical rigidity of the rubber without considering influence of bending deformation.SOLUTION: A vertical rigidity adjustment mechanism 50 includes: a laminated rubber 51 that is provided so as to be overlapped with a laminated rubber bearing 40 in a vertical direction in a second laminated rubber base isolation device 30, and on which a load of a superstructure 12 to be a base isolation object acts; and a horizontal constraint part 52 that is provided so as to surround the periphery of the laminated rubber 51. Here, the horizontal constraint part 52, while allowing deformation of the laminated rubber 51 in the vertical direction, constrains deformation of the laminated rubber 51 in a horizontal direction continuously from the upper end of the laminated rubber 51 to the lower end thereof.SELECTED DRAWING: Figure 3
【課題】積層ゴム免震装置の鉛直剛性調整機構が備えるゴムの水平方向の変形を拘束した領域に曲げ変形が生じることを防止し、該ゴムの鉛直剛性を、曲げ変形の影響を考慮せずに設定できるようにする。【解決手段】鉛直剛性調整機構５０は、第２の積層ゴム免震装置３０において積層ゴム支承４０と鉛直方向に重ねて設けられ免震対象の上部構造物１２の荷重が作用する積層ゴム５１と、積層ゴム５１の周りを囲うように設けられた水平拘束部５２とを備える。ここで、水平拘束部５２は、積層ゴム５１の鉛直方向への変形を許容するのに対して、積層ゴム５１の水平方向への変形を、積層ゴム５１の上端から下端まで連続的に拘束する。【選択図】図３
