H-shaped steel application
The section shape of H-beam is economical and reasonable, and the mechanical properties are good. When rolling, every point on the section extends more evenly and the internal stress is small. Compared with ordinary I-beam, H-beam has the advantages of large section modulus, light weight and metal saving, which can reduce the building structure by 30-40%. And because its legs are parallel inside and outside, the leg end is right Angle, assembly and combination into components, can save welding, riveting workload up to 25%. It is often used in large buildings requiring large bearing capacity and good cross-section stability (such as factory buildings, civil buildings, etc.), as well as Bridges, ships, lifting transport buildings, equipment foundations, support babies, foundations, etc.
The H-shaped steel structure can effectively overcome the defects of large self-loading and large structural size of the steel bar source structure. And improve the proof of the structure, improve the seismic performance of the structure. The steel structure building with hot rolled H-shaped steel as the main material of the structure, through the factory production of steel beams and steel columns as the skeleton, and with a new lightweight thermal insulation, thermal insulation, high-strength wall material as the envelope structure.
It has the advantages of high strength, large span, light weight, good lateral force resistance, small structural section size, short construction period, and can improve the utilization coefficient of building area and improve economic benefits. Because the material of H-beam steel can be completely recycled and reused. The impact on the environment is minimal, so hot-rolled H-shaped steel enjoys a reputation as a green building material in the field of building steel structures.
