To provide a laminate rubber seismic isolation bearing capable of improving weather resistance without using cover rubber.SOLUTION: A laminate rubber seismic isolation bearing comprises a laminate rubber body formed by alternately laminating a rubber plate and a rigid plate, and a pair of flange plates connected to the upper and lower end surfaces of the laminate rubber body. The thickness of the outer peripheral part of the rigid plate is larger than the thickness of a body part, which is the central side of the rigid plate. According to such a configuration, it is possible to reduce an area where the rubber plate is exposed to outside air and improve weather resistance without using cover rubber.SELECTED DRAWING: Figure 1
【課題】カバーゴムを使用しなくても耐候性を向上できる積層ゴム型免震支承を提供する。【解決手段】積層ゴム型免震支承は、ゴム板と剛性板とを交互に積層して形成された積層ゴム体と、その積層ゴム体の上下両端面に接合された一対のフランジ板とを備える。剛性板の外周部の厚みは、その剛性板の中心側となる本体部の厚みよりも大きい。かかる構成によれば、カバーゴムを使用しなくても、ゴム板が外気に触れる範囲を減らして耐候性を向上することができる。【選択図】図１
