Improved support seat with functions of energy consumption, and seismic mitigation and isolation

Abstract

The invention discloses an improved support seat with the functions of energy consumption, and seismic mitigation and isolation, and belongs to the technical field of anti-seismic designs of bridge engineering. The improved support seat disclosed by the invention comprises an upper cover plate, wherein an upper connection plate is fixed below the upper cover plate, a lead core is fixed at the centre below the upper connection plate, a lower connection plate is fixed below the lead core, and a lower cover plate is fixed below the lower connection plate; a rubber high-strength metal plate mixed cushion layer is arranged between the upper connection plate and the lower connection plate, the rubber high-strength metal plate mixed cushion layer sleeves the lead core, and an anti-corrosive rubber protection layer is arranged on the outer sidewall of the rubber high-strength metal plate mixed cushion layer; and U-shaped dampers are arranged between the upper cover plate and the lower cover plate at the outer side of the anti-corrosive rubber protection layer, each U-shaped damper is fixed on the upper cover plate and the lower cover plate through high-strength bolts, and a rubber cushion layer is arranged between each upper high-strength bolt and the corresponding U-shaped damper. The improved support seat disclosed by the invention has the characteristics of being high in damping, stable in energy consumption, capable of resisting high seismic action, and the like. In addition, each U-shaped damper is connected with a main body part of the support seat through the high-strength bolts, and therefore is convenient to replace.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic technology of bridge engineering, and in particular relates to an improved energy-dissipating and shock-absorbing support, which is suitable for the support structure form of multi-level fortification standards. Background technique [0002] The current bridge bearing is one of the key technologies in bridge anti-seismic, and has been highly valued and concerned by the academic and engineering circles at home and abroad. At present, with the frequent occurrence of earthquakes, many problems have been exposed in the anti-seismic aspects of bridge supports, such as insufficient vertical bearing capacity in the support structure, inability to effectively consume seismic energy, resulting in serious bridge damage, and insufficient horizontal isolation capacity, etc. . And, when encountering larger earthquake action, bridge collapses, can cause very big harm to people's property and safety. The ...

Problems solved by technology

At present, with the frequent occurrence of earthquakes, many problems have been exposed in the anti-seismic aspects of bridge supports, such as insufficient vertical bearing capacity in the support structure, inability to effectively consume seismic energy, resulting in serious bridge damage, and insufficient horizontal isolation capacity, etc.

Moreover, when encountering a large earthquake, the bridge collapses, which will cause great damage to people's property and safety.
