Description

Technical Field

[0001] This utility model belongs to the field of support technology, and in particular relates to a steel box girder construction support bracket that can be quickly assembled and disassembled. Background Technology

[0002] In the field of steel box girder construction, traditional temporary supports often employ structures such as steel pipe piles, Bailey bridges, or full-span scaffolding, which suffer from low load-bearing efficiency, long assembly and disassembly cycles, and poor adaptability. Especially when constructing across rivers or in areas with heavy traffic, existing supports often require extensive on-site welding, making it difficult to guarantee installation accuracy. Furthermore, they are prone to instability due to changes in terrain and load, leading to high construction costs and significant safety risks. In addition, conventional supports are difficult to adjust in height and horizontal position flexibly, failing to meet the dynamic adjustment requirements of segmented hoisting of large-span steel box girders, thus affecting the accuracy of beam alignment control. Patent literature generally points out that such technologies are no longer suitable for the modern trend of efficient and prefabricated bridge construction. Utility Model Content

[0003] In view of this, the present invention aims to provide a quick-assembly and disassembly steel box girder construction support bracket to solve at least one technical problem in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A quick-assembly and disassembly steel box girder construction support bracket includes several support devices and a first connecting component, wherein the several support devices are connected to each other through the first connecting component; The support device includes a load-bearing structure, a top support component, and a second connecting assembly; Several load-bearing structures are arranged in parallel and connected by a second connecting component, with a top support component positioned above the load-bearing structures. The load-bearing structure includes load-bearing column assemblies and base assemblies. Several load-bearing column assemblies are connected in sequence, and the base assemblies are located at the bottom of the load-bearing column assemblies.

[0005] Furthermore, the load-bearing column assembly includes a column body, a first connecting flange, and a second connecting flange; the first connecting flange and the second connecting flange are respectively disposed on the upper and lower sides of the column body, and several columns are bolted together through the first connecting flange and the second connecting flange; The first connecting flange has several evenly distributed first connecting holes along its circumference; The second connecting flange has several evenly distributed second connecting holes along its circumference; The first connecting flange and the second connecting flange are provided with several evenly distributed first reinforcing ribs along the circumference.

[0006] Furthermore, the base assembly includes a rectangular base, a first T-shaped frame, a second T-shaped frame, and a bottom support column; Two first T-shaped frames are arranged in parallel on a rectangular base, and two second T-shaped frames are arranged in parallel between the first T-shaped frames. The second T-shaped frames are arranged perpendicular to the first T-shaped frames, and the two first T-shaped frames and the two second T-shaped frames surround to form a rectangular area. The bottom of the bottom support is positioned above the rectangular base and within the rectangular area.

[0007] Furthermore, the bottom support column is provided with a third connecting flange at the top, and the third connecting flange is provided with several evenly distributed third connecting holes. The bottom support column is bolted to the load-bearing column assembly through the third connecting flange. The bottom support column is provided with evenly distributed second reinforcing ribs around its perimeter.

[0008] Furthermore, both the second T-shaped frame and the first T-shaped frame are provided with a third reinforcing rib corresponding to the position of the second reinforcing rib.

[0009] Furthermore, the top support includes a top support frame and a top support column; The bottom of the top support frame is bolted to the first connecting flange of several load-bearing column assemblies, and several top support columns are evenly arranged on the top of the top support frame.
