Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a reinforced steel structure at a joint of a corrosion-resistant steel structure. Background Art

[0002] Steel structure has the characteristics of high strength and light weight. Compared with concrete and wood, its density and yield strength are lower. Therefore, under the same stress conditions, steel structure components have small cross-sections, light weight, easy transportation and installation, suitable for large spans, high heights, heavy load structures, suitable for bearing impact and dynamic loads, and have good seismic resistance.

[0003] The application number is 202320286129.8, which discloses a reinforcement structure at the joint of a steel structure, including a fixed steel structure crossbeam and a steel structure column. A main reinforcement connection assembly is arranged at the joint of the steel structure crossbeam and the steel structure column. The main reinforcement connection assembly includes an inclined reinforcement brace, and a crossbeam fixing part and a column fixing part are respectively fixedly installed at the upper and lower ends of the reinforcement brace. The crossbeam fixing part is fixed on the steel structure crossbeam at the corresponding position, and the column fixing part is fixed on the steel structure column at the corresponding position. A beam-column locking assembly is installed on the inner side of the main reinforcement connection assembly. The reinforcement structure at the joint of the steel structure is mainly used to strengthen the connection of the steel structure crossbeam and the steel structure column to ensure the connection stability and reliability of the connection strength of the joint of the entire steel structure under complex outdoor working conditions.

[0004] However, there are some shortcomings. In this practice, the reinforced diagonal braces are fixed by drilling holes on the beams and columns and connecting them with bolts. This method will damage the steel structure frame body and may affect the strength of the steel structure frame, and even affect the service life of the steel structure frame. Utility Model Content
