Abstract

An earthquake-insulating bearing assembly is mounted between a foundation and a building structure. A first friction member is fixedly secured to a lower surface of the building structure. An elastic bearing is interposed between and fixed relative to an upper surface of the foundation and the lower surface of the building structure. A guide means is vertically mounted on the upper surface of the foundation. A second friction member of an annular shape is disposed around the elastic bearing and is engaged with the guide means for vertical movement therealong. An urging means is fixed relative to the upper surface of the foundation for urging the second friction member into frictional engagement with the first friction member under a selected load. The urging means comprises means for adjusting the load applied to the second friction member.
