EARTHQUAKE-PROOFING DEVICE

摘要

An earthquake-proofing device for buildings comprises an upper plate (1) provided with two or more metal wedges (5) with their sloping plane surfaces (5a) facing downwards and outwards; a lower plate (2) provided with two or more metal wedges (8) with their sloping plane surfaces (8a) facing upwards and inwards opposite the sloping surfaces (5a) of the upper plate; and two or more elastomeric sheets (3) arranged between the sloping surfaces (5a, 8a) of the upper and lower plates to establish a mechanical connection therebetween. The device may be used in railway bridges.
