An anti-overturning diagonal bracing reinforcement device for single-column pier bridges

Abstract

The invention provides a single column pier bridge anti-overturning inclined strut reinforcing device. The single column pier bridge anti-overturing inclined strut reinforcing device comprises a positioning block, a driving structure which comprises a fourth rotating shaft, a sleeve, a sliding rod, a fifth rotating shaft and a driving rod, wherein the sliding rod is rotationally connected with thepositioning block through the fifth rotating shaft, the sliding rod is slidably connected with the sleeve, the driving rod is connected to the sleeve and the sliding rod in a penetrating mode, the driving rod is rotatably connected with the sleeve, the driving rod is in threaded connection with the sliding rod, and the fourth rotating shaft is arranged at the end, away from the sliding rod, of the sleeve; a supporting structure which comprises a first supporting rod, a second supporting rod, a second rotating shaft and a third rotating shaft; a limiting structure which comprises a limiting sleeve and a first rotating shaft; and a fixing structure. The single column pier bridge anti-overturing inclined strut reinforcing device has the advantages of being flexible in operation, high in construction efficiency and good in reinforcing effect.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an anti-overturning diagonal brace reinforcement device for single-pillar pier bridges. Background technique [0002] Single-pillar bridges are widely used in urban bridges and high-speed interchange ramps due to the advantages of small clearance under the bridge, simplicity and smoothness, beautiful appearance, strong adaptability, and good economy. With the rapid development of my country's economy, traffic flow and The load of vehicles is constantly increasing. At the same time, due to the lack of safe driving knowledge of some drivers, the vehicles are overloaded and deflected, which has caused many overturning accidents in the single-pillar bridge during use. The bridge needs to be reinforced by reinforcement devices. For example: the application number is Patent No. 201621294927.1 discloses a single column pier bridge anti-overturning diagonal brace reinforcement device....

[0002] Single-pillar bridges are widely used in urban bridges and high-speed interchange ramps due to the advantages of small clearance under the bridge, simplicity and smoothness, beautiful appearance, strong adaptability, and good economy. With the rapid development of my country's economy, traffic flow and The load of vehicles is constantly increasing. At the same time, due to the lack of safe driving knowledge of some drivers, the vehicles are overloaded and deflected, which has caused many overturning accidents in the single-pillar bridge during use. The bridge needs to be reinforced by reinforcement devices. For example: the application number is Patent No. 201621294927.1 discloses a single-pillar pier bridge anti-overturning diagonal brace reinforcement device

[0003] However, the anti-overturning oblique bracing device disclosed in the patent application number 201621294927.1 does not apply prestress to the bridge, and the supporting effect is poor. It is necessary to select the installation position according to the length of the supporting rod, and the construction is difficult.
