Bridge support shock absorption device

Abstract

The invention relates to the technical field of shock absorption devices, in particular to a bridge support shock absorption device. An insulation layer is fixed to the lower side of an upper fixing board. An upper decompression board is fixed to the lower side of the insulation layer. An annular limiting groove is formed in the outer side of the upper decompression board. An annular limiting board is arranged on the upper side of a lower fixing board. An annular limiting block is arranged on the inner side of the annular limiting board and clamped in the annular limiting groove. Multiple reset springs are fixed to the portion, on one side of the annular limiting groove, of the upper decompression board. The other side of each reset spring is fixed to the annular limiting block. A lower decompression board is arranged in the position, located on the inner side of the annular limiting board, on the upper side of the lower fixing board. Multiple buffering grooves are formed in the lowerdecompression board. Multiple T-shaped decompression rods are fixed to the lower side of the upper decompression board and matched with the multiple buffering grooves. Strong springs are fixed to thelower sides of the T-shaped decompression rods. The lower sides of the strong springs are fixed to the lower decompression board. The bridge support shock absorption device is simple in structure, andshocks of a bridge can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of shock absorbing devices, in particular to a bridge support shock absorbing device. Background technique [0002] Bridge bearings are important structural components connecting the bridge superstructure and substructure. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the upper structure of the bridge to the lower structure of the bridge, so that the actual stress of the structure is consistent with the theoretical diagram calculated. Currently, there are fixed basin rubber supports Seats, movable basin-type rubber bearings, etc., they mainly resist earthquake force by improving their structural strength, have low earthquake resistance, and are easily corroded. Therefore, we propose a bridge support shock absorber. Contents of the invention [0003] The object of the present invention is to propose a bridge support damping device in order to solve the sho...
