Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically a highly stable I-beam steel structure. Background Technology

[0002] As modern architecture evolves towards longer spans (such as stadiums and bridges) and super high-rises (such as skyscrapers), traditional structural forms are struggling to meet load-bearing and spatial requirements. I-beam steel structures, by optimizing cross-sectional distribution, significantly improve bending stiffness. For example, in bridge main beams, they can reduce material usage while maintaining span performance.

[0003] In publication number CN212153708U, this utility model provides a steel structure, belonging to the field of steel structure building technology. The steel structure includes: a first steel column, a second steel column, and a sleeve. The sleeve is a hollow structure with openings at both ends. The first and second steel columns are respectively inserted into the openings at both ends of the sleeve. Multiple through holes are provided on the sleeve wall. The first and second steel columns are welded to the sleeve through these through holes. The edges of the openings at both ends of the sleeve form weld layers with the outer walls of the first and second steel columns, respectively. This utility model reduces the processing steps before welding the steel columns and also lowers the difficulty of welding between the steel columns.

[0004] The above-mentioned steel structure connection method is relatively simple, the connection structure is not stable enough, and the installation and use are relatively troublesome. Therefore, there is an urgent need for a highly stable I-beam steel structure with more stable connection and easier installation and fixing. Utility Model Content
