The steel frame factory building mainly refers to the main load-bearing components are composed of steel. Including steel columns, steel beams, steel structure foundations, steel roof trusses, steel roofs, and walls of steel structure workshops are now mostly made of new insulation materials.
Industrial and civil construction facilities built with steel are called steel structure buildings. Due to the increase in steel production, many enterprises have begun to adopt steel structure workshops, which can be divided into light and heavy steel structure factory buildings. Compared with structures made of other materials, steel structures are cheaper, and steel frame factory building have the following characteristics.
1. The strength of steel is high, and the structure is light in weight
Although the density of steel is higher than that of other building materials, its strength is very high. Under the same force, the steel structure has a small weight and can be made into a structure with a large span.
2. Good plasticity and toughness of steel
The plasticity of steel is good, and the structure will not break suddenly due to accidental overload or partial overload under normal circumstances. The toughness of steel makes the structure more adaptable to dynamic loads.
3. Uniform steel material, high reliability
The internal structure of the steel is uniform and isotropic. The actual working performance of the steel structure is in good agreement with the theoretical calculation results adopted. Therefore, the reliability of the structure is high.
4. Steel has weldability
Due to the weldability of steel, the connection of steel frame factory buildings is greatly simplified, and it is suitable for manufacturing structures of various complex shapes.
5. High degree of industrialization of steel structure fabrication and installation
The manufacture of steel structures is mainly carried out in specialized metal structure factories, so the manufacture is simple and the precision is high. The finished components are transported to the site for installation, with a high degree of assembly, fast installation speed and short construction period.
6. Good sealing of steel structure
The internal structure of steel is very dense, and when it is connected by welding, or even by rivets or bolts, it is easy to achieve tightness and no leakage.
7. Heat-resistant steel structure
When the surface temperature of the steel is within 1500°C, the strength of the steel changes little, so the steel structure is suitable for hot workshops.
