SLIDING BASE-ISOLATING BEARING DEVICE AND BASE-ISOLATING BEARING STRUCTURE USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a sliding base-isolating bearing device which is equipped with a sliding member having low velocity dependence and setting a coefficient of friction at a low value of 0.02 or less, in sliding friction between the sliding member and a smooth plate as the other member, which can reduce the transmission even of vibrations, generated by small-scale earthquakes etc., to an upper structure and which can achieve the sure protection of the upper structure, and a base-isolating bearing structure which is equipped with the sliding and base-isolating bearing device. PSOLUTION: The base-isolating bearing device 1 is equipped with: a sliding base-isolating bearing 6 which comprises a laminated rubber body 4 constituted by alternately laminating a reinforcing plate 2 and a rubber layer 3 and the sliding member 5 fixed to the undersurface of the laminated rubber body 4; and the smooth plate 7 which serves as the other material slidably abutting on the sliding member 5 of the bearing 6.
