Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to an H-shaped steel ring belt truss. Background Art

[0002] H-shaped steel belt truss is a structural system that uses H-shaped steel as the main component. It is widely used in places that require high bearing capacity and rigidity, such as large-span buildings and industrial plants. Its main features include high bearing capacity, good stability, high material utilization rate, and convenient construction. The H-shaped steel section has high bending and shear strength, which enables it to withstand large loads. At the same time, its geometric shape gives the truss structure good stability and can effectively resist lateral instability. High material utilization rate is also one of the advantages of H-shaped steel. Its cross-sectional shape makes the use of steel more economical. In addition, H-shaped steel components can be prefabricated in the factory, and on-site assembly reduces construction time and on-site workload, improving construction efficiency. H-shaped steel belt trusses are widely used in large-span roof structures such as gymnasiums, exhibition halls, etc., and are also commonly used in bridge structures, especially large-span highway or railway bridges. In addition, industrial buildings such as factories and large warehouses also often use this structural system.
