[0002] Bridges are one of the most common construction facilities at present, and their substructures include abutments, piers and foundations. During the current bridge construction process, common operations include installing support devices on the bridge piers to complete some related operations. For example, before erecting the bridge deck on the bridge columns, it is necessary to fix the support plates on the bridge columns to facilitate the laying of steel bars. Highway bridge projects include the main bridge project and the ancillary engineering facilities in the overall bridge position. During the construction process, brackets are required to support them. For example, in the maintenance of bridges, support brackets are often required. The support brackets can enhance the stability and safety of the bridge construction through support, and can also facilitate the construction of workers. However, the existing support structure has a high construction cost. Most of the existing support brackets for bridge construction are installed by complex welding methods. The installation structure is relatively cumbersome, and it is inconvenient to install and remove. The overall stability needs to be improved, and the redundant and complex welding will cause the related support components to be unable to be reused. Utility Model Content
