Abstract
PURPOSE: To improve aseimic base insulation performance and damper performance by a method wherein the physical properties of a flexible plate of an aseimic base insulation structure is set to a given hysteresis ratio during 100% tensile deformation at 25 deg.C and a ratio of a given storage elastic modulus during 5 Hz, 0.01% deformation at -10 deg.C and 30 deg.C. CONSTITUTION: A plurality of rigid plates 12 having rigidity and flexible plates 11 having viscoelastic property are alternately laminated together to form an aseimic base insulation structure 20. The material of the flexible plate 11 is prepared that one kind or more kinds selected from a filler, a softener, a plasticizer, oil, oligomer, and a lubricant are mixed in rubber and vulcanized. The property of the flexible plate 11 is that a hysteresis during 100% tensile deformation at 25 deg.C is set to 0.2-0.7 and a ratio E (-10)/E (30) 30 deg.C of a storage elastic modulus during 5 Hz, 0.01% deformation at -10 deg.C and 30 deg.C is set to 1.0-3.0. This constitution improves aseimic base insulation performance and damper performance.
