Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a support bracket for highway bridge construction. Background Art

[0002] Support brackets, commonly used in highway bridge construction, are temporary structures used to support the construction loads of the bridge superstructure.

[0003] If the bracket cannot be quickly adjusted, it will need to be dismantled and rebuilt at different construction stages, wasting time and labor. Secondly, bridge construction requires multiple adjustments to the bracket position, and traditional fixed brackets cannot meet the rapid adjustment requirements, delaying construction progress.

[0004] Secondly, if the bracket position is not firmly fixed after being changed, it may cause slippage or tipping under the construction load, increasing construction risks. In addition, the unstable position will lead to inaccurate positioning of the formwork and bridge components, affecting the construction quality and design requirements of the bridge.

[0005] Finally, traditional supports are complicated to disassemble and assemble, which takes a lot of time and is not conducive to bridge projects with tight schedules. Construction workers need to invest more energy and time in complex disassembly and assembly work, which increases the difficulty of construction. Utility Model Content
