High stability aseismic bearing

摘要

A high stability bearing includes two or more plates each of which has three or more disc shaped bearings mounted on or formed integrally with a surface or surfaces thereof, the disc shaped bearings and adjacent plates being joined together to form a bearing assembly with, the disc shaped bearings being linked or stiffened by the plates to form a stable unit. The disc shaped bearings are preferably constructed from a synthetic or natural rubber material having a shore hardness in the range of about 30 to 80. Each plate or an assembled set of plates can have a skirt which protects the interior of the assembly against the ingress of deleterious matter to the space or spaces between adjacent plates. The assembly can also include the provision of damping within the bearing by incorporating an energy absorbing component or components within or between the layers of the bearing.
