An anti-overturning energy consumption reinforcement device for single-pillar pier bridges

Abstract

The invention discloses an anti-overturning energy consumption reinforcement device for a single column pier bridge, which comprises: a half ring hoop, two halves of the ring hoop are tightly hooped on both sides of the bridge pier; at least one group of energy dissipation components, each group including two The energy components are symmetrically distributed on both sides of the bridge pier; the energy dissipation components include a first energy dissipation element and at least one second energy dissipation element extending longitudinally along the bridge pier; the first energy dissipation element includes a first main body, at least one side of which is along the There are a plurality of first energy dissipation boards arranged longitudinally; the second energy dissipation member includes a second main body part, and a plurality of second energy dissipation boards are arranged longitudinally on the second main body part, the first energy dissipation board, the second energy dissipation board The energy plates extend laterally along the bridge; the upper end of the first main body part is connected to the bridge, the lower end of the second main body part is installed on the semi-circular hoop, and the plurality of first energy dissipation plates and the plurality of second energy dissipation plates are connected to each other. wear. The invention realizes the consumption of partial load and vibration energy of the bridge, and the anti-overturning energy-consuming reinforcing device can be quickly disassembled and replaced, so as to maintain the optimal anti-overturning ability of the bridge.

Description

technical field [0001] The invention belongs to the technical field of bridge reinforcement, in particular to an anti-overturning energy dissipation reinforcement device for a single-column pier bridge. Background technique [0002] In recent years, in order to relieve traffic pressure, many cities have built numerous urban viaducts and overpasses. Single-column pier bridges are widely used due to their advantages of small footprint, large space under the bridge, and simple shape. However, the single-column pier bridge adopts a single bearing form in the transverse bridge direction, and the lateral restraint on the main beam is weak. Under large eccentric load vehicles or earthquakes, the bearing will be emptied, causing the main beam to overturn laterally. Therefore, the anti-overturning reinforcement of the existing single-column pier bridges can effectively reduce the risk of overturning and damage of urban bridges and prolong the service life of the bridges. However, t...

AI Technical Summary

Problems solved by technology

However, the existing anti-overturning reinforcement devices for single-column pier bridges often only focus on the support and reinforcement of the bridge, while ignoring the energy consumption of bridge vibration and eccentric loads, and the existing reinforcement devices often have irreversible damage. In the case of a large unbalanced load again, the reinforcement device cannot provide optimal support, which also causes the bridge to overturn
