a shock absorber

Abstract

The invention provides a shock absorbing device, comprising a top plate, a bottom plate and intermediate damping members arranged between the top plate and the bottom plate, wherein the intermediate damping members are capable of producing lateral horizontal movement and horizontal rotation along the top plate, and the intermediate damping members are connected with the bottom plate and are capable of producing lateral horizontal movement along the bottom plate. The intermediate damping members are uniformly arranged laterally along the top plate and the bottom plate, and each intermediate damping member comprises two arc-shaped steel structures that are symmetrically arranged and connected with each other into a whole. The shock absorbing device provided by the invention can adapt to thelateral seismic displacement of a bridge, provide additional damping dissipation input energy for the bridge and provide lateral yielding force for the bridge to prevent beam falling when meeting theearthquake or hurricane.

Description

technical field [0001] The invention belongs to the technical field of bridge damping, and in particular relates to a damping device. Background technique [0002] In normal operation or frequent earthquakes, the bridge can rely on the friction of the bridge bearing to meet the service requirements. However, under extreme working conditions such as hurricanes and rare earthquakes, the bridge bearings bear large horizontal loads, resulting in large horizontal displacements, which are likely to cause bridge beam drop damage. The existing anti-drop beam devices are mainly brittle concrete blocks and lateral buffer rubber pads. However, it is found in engineering practice that the concrete blocks are prone to failure due to brittle shear failure, which leads to the failure of bridge drop beams. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a bridge that can adapt to t...
