US 6,688,051 B2 · Structure of an anti-shock device

Abstract

An improvement in the structure of an anti-shock device utilized for buildings, important structures and bridge structures that includes a base, a carrier, a slide block, and a plurality of springs. A slip concavity of a sunken round curved recess is respectively formed in the base top surface and in the carrier bottom surface, and an upper slide block member and a lower slide block member are situated between the two slip concavities. One contact surface between the two slide block members and slip concavities is of a curved contour and the other surfaces are indented seating recesses. A spheroid coupling bearing is nested between the two seating recesses and the upper and lower slide block members are held together by the springs. As so assembled, the anti-shock device base is fastened under the columns of a building structure such that the building achieves the objectives of exceptional shock eliminating capability and greater building structure safety.
