Anti-overturning reinforcing device for additional steel structure support of single-column pier bridge

Abstract

The invention belongs to the technical field of single-column-pier bridge reinforcement, and discloses a single-column-pier bridge additional steel structure support anti-overturning reinforcing device which comprises a first supporting piece fixed to a pier. The second supporting piece is supported between the bridge pier and the bridge, the second supporting piece is located on one side of the bridge pier in the transverse direction of the bridge, and the second supporting piece comprises a lower base fixed to the first supporting piece, and a supporting plate capable of ascending and descending is arranged in the lower base; the upper seat is fixed to the bottom of the bridge, the upper seat is in sliding fit with the lower seat, an elastic supporting piece and a driving assembly are connected between the upper seat and the supporting plate, the driving assembly is installed on the lower seat, and when the upper seat is pressed to be close to the lower seat, the supporting plate is driven by the driving assembly to move upwards; in conclusion, based on the arrangement of the second supporting piece, the reinforcing device can automatically provide larger supporting force on the side with the large bearing capacity, and then the problem that the bridge overturns due to the fact that the bearing capacity is too large is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of bridge reinforcement for single-column piers, and in particular relates to an anti-overturning reinforcement device for additional steel structure supports of single-column pier bridges. Background technique [0002] Single-column pier bridges are widely used in urban bridges and high-speed interchange ramps because of their advantages of small clearance under the bridge, simple and smooth, beautiful appearance, strong adaptability, and good economy. However, in practical applications, due to the poor lateral stability and safety of the bridge deck system supported by a single point of a single-column pier bridge, especially when the vehicle is severely overloaded and yawed, the bridge is prone to overall imbalance due to excessive lateral load. Overturning is a serious accident, so an anti-overturning reinforcement device with good supporting effect and easy installation is urgently needed. SUMMARY OF ...

AI Technical Summary

Problems solved by technology

However, in practical applications, due to the poor lateral stability and safety of the bridge deck system with single-point support of single-column pier bridges, especially when vehicles are seriously overloaded and deflected, the bridge is prone to overall failure due to excessive and unbalanced lateral loads. Overturning vicious accidents, so there is an urgent need for an anti-overturning reinforcement device with good supporting effect and easy installation
