H section steel is a new type of economic building steel. The section shape of H beam is economical and reasonable, and the mechanical properties are good. When rolling, each point on the section extends more evenly and the internal stress is small. Compared with ordinary I-beam, it 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 a right Angle, assembly and combination into components, can save welding, riveting work up to 25%. It is often used in large buildings (such as factories, high-rise buildings, etc.) that require large bearing capacity and good cross-section stability, as well as Bridges, ships, hoisting machinery, equipment foundation, bracket, foundation pile, etc.
H section steel is a kind of economic section steel with better mechanical properties, which is optimized and developed from I section steel, especially the section with the same English letter "H". Its characteristics are as follows:
Wide flange and high lateral stiffness.
Strong bending ability, about 5%-10% than I-beam.
The two surfaces of the flange are parallel to each other, which makes the connection, processing and installation easy.
Compared with welding I-beam, low cost, high precision, low residual stress, no need for expensive welding materials and weld detection, saving steel structure production cost about 30%.
Under the same section load. Hot rolled H steel structure is 15%-20% lighter than traditional steel structure.
Compared with concrete structure, the use area of hot-rolled H steel structure can be increased by 6%, and the self-weight of the structure can be reduced by 20% to 30%, thus reducing the internal force of the structure design.
H beam can be processed into T beam, honeycomb beam can be combined to form various section forms, greatly meet the needs of engineering design and production.
1, high structural strength
Compared with the I-beam, the section modulus is large, and the bearing condition is the same at the same time, the metal can be saved by 10-15%.
2. Flexible and rich design style
In the case of the same beam height, the steel structure of the bay is 50% larger than the concrete structure, so that the building layout is more flexible.
3. Light weight of structure
Compared with the concrete structure, the weight of the structure is light, the reduction of the weight of the structure, reduce the internal force of the structure design, can make the building structure foundation processing requirements are low, the construction is simple, the cost is reduced.
4. High structural stability
The hot rolled H-beam is the main steel structure, its structure is scientific and reasonable, good plasticity and flexibility, high structural stability, suitable for bearing vibration and impact load of large building structure, strong ability to resist natural disasters, especially suitable for some building structures in earthquake zones. According to statistics, in the world of magnitude 7 or more devastating earthquake disaster, H-shaped steel mainly steel structure buildings suffered the least degree.
5. Increase the effective use area of structure
Compared with concrete structure, steel structure column section area is small, which can increase the effective use area of the building, depending on the different forms of the building, can increase the effective use area of 4-6%.
6. Save labor and materials
Compared with welding H-beam steel, it can significantly save labor and materials, reduce the consumption of raw materials, energy and labor, low residual stress, good appearance and surface quality.
