Steel structure is composed of steel materials and one of the most important types of buildings. This design mainly consists of steel beams, columns, beams, and other structures, as well as steel plates. It adopts anti-corrosion and anti-corrosion processes such as silicate, pure manganese phosphating, dry cleaning, and galvanizing. The connection of components or parts generally adopts welding Using bolts or rivets. Lightweight and simple in structure, widely used in large workshops, activity venues, super skyscrapers, and other fields.
Steel has the characteristics of high strength, light weight, good overall strength, and strong deformation ability. Therefore, it is particularly suitable for the construction of large, ultra large, and ultra heavy buildings; The material has good uniformity and isotropy, and is an ideal elastic material, which best conforms to the basic assumptions of general Applied mechanics; This material has good ductility and viscosity, can generate significant deformation, and can withstand dynamic loads well; It has a high level of industrialization and can be produced through a high degree of mechanization and specialization.

Features:
1. High material strength and light weight
Steel has high strength and high modulus of elasticity. Compared with concrete and wood, the ratio of its density to tensile strength is relatively low, so under the same load conditions, the steel structure has a small cross-section and light weight, suitable for transportation and installation, and suitable for large buckles, high heights and heavy loads.
2. Steel toughness, good plasticity, uniform material and high structural reliability
It fits to keep shocks and dynamic loads and has good systemic abilities. The internal structure has become reverse, close to the isotopic gamma body. The actual desktop capabilities are more consistent with the calculation theories. Therefore, the reliability of the steel structure is high.
3. High degree of mechanization of steel structure manufacturing and installation
Steel structures are easy to manufacture and assemble in the factory. Factory mechanized production of steel structural components with high precision, high production efficiency, fast on-site assembly speed, and short construction cycle. Steel structures are the most industrialized.
4. Good sealing performance of steel structure
Due to the fact that the welded structure can be completely sealed, it can be used in high pressure tanks, large oil pools, pressure pipelines, etc. are produced. with good air and water resistance.
5. Steel structure is heat-resistant and not fire-resistant
If the temperature is below 150° C, the performance of the steel does not change much. Therefore, steel structures are suitable for high-temperature workshops, but if the surface of the structure is exposed to thermal radiation of about 150° C, insulating panels should be used for protection. When the temperature is between 300° C and 400° C, the strength and modulus of elasticity of the steel decreases significantly. At about 600° C, the strength of the steel tends to zero. In buildings with special fire protection requirements, steel structures should be protected with refractory materials to improve their fire resistance.
6. Poor corrosion resistance of steel structure
Especially in humid and corrosive environments where there are many corrosive media, it is easy to rust. Generally, steel structures require rust removal, galvanizing, or painting, and regular maintenance is required. Special measures such as "zinc block anode protection" need to be taken for the structure of offshore platforms in seawater to prevent corrosion.
7. Low carbon, energy saving, green and environmental protection, reusable
When dismantling steel structures, there is almost no construction waste generated, and steel can be recycled and reused.
Compared with ordinary reinforced concrete structures, steel structures have the characteristics of strong uniformity, fast construction speed, good seismic performance, and fast recovery speed. The strength and elastic modulus of steel are several times that of bricks and concrete. Under the same conditions, steel structures are lighter in weight. From the perspective of damage, advanced steel structures have significant signs of deformation and are flexible emission structures that can detect hazards in advance and avoid them.
The steel structure workshop has the advantages of light weight, basic economy, few materials, low cost, short construction time, large span, safety and reliability, beautiful appearance, and stable structure. The steel structure workshop is used in large industrial factories, warehouses, cold storage, high-rise buildings, office buildings and other construction industries, Multiple widely used storage areas and residential buildings
Prefabrication of steel elements:
The prefabrication and assembly of steel structures are carried out on the steel platform in accordance with the installation sequence and process requirements, and welding quality must be ensured.
The distance between the flange joint of the profile steel splicing and the core joint should be greater than 200mm, and the length of the flange joint should not be less than twice the width of the plate; Core splicing width not less than 300 mm, length not less than 600 mm.
To facilitate welding and ensure welding quality, try to perform butt welding on the steel floor platform according to the dimensions specified in the design drawings. Try to perform butt welding on the columns, reinforcement plates, connecting plates, bearing plates, and beams (beams).
In addition to manufacturing and assembling prefabricated steel components on steel platforms according to design drawings and specifications, it is also necessary to consider the manufacturability of on-site assembly and changes in installation dimensions.
