The main load-bearing components of steel structure factory building include steel columns, steel beams, portal steel frames and various supports. These components are connected together by welding, bolts or rivets to form a complete load-bearing system.
Among them, steel columns are the main vertical load-bearing components of the factory building, usually made of H-shaped steel or lattice steel pipes. The cross-sectional form of the steel column is determined according to the specific stress requirements and the height of the factory building. Its height is generally equal to the height of the factory building.
Steel beams are transverse load-bearing members, which can be solid-web or open-web depending on span, load and wind resistance requirements. Solid-web steel beams have a large cross-section and can withstand larger bending moments and shear forces, while hollow-web steel beams have a small cross-section but smaller bending stiffness and are generally used in situations with larger spans or smaller stresses.
The portal steel frame is a parallel intersecting planar structure composed of steel columns and steel beams. It has large load-bearing capacity and stiffness, and also has good seismic resistance and ductility. The structural form of the portal steel frame can be adjusted according to specific needs, and its height and span can also be selected according to actual needs.
Various supports include roof supports, column supports and ties, etc., which are mainly used to withstand tension and pressure and enhance the stability and stiffness of the structure. The form of support can be selected according to the specific conditions and stress requirements of the factory building, including angle steel, round steel, H-shaped steel, etc.
In addition, the walls of steel structure factory building is generally made of lightweight materials, such as color steel plates, aerated concrete panels, etc., which can not only reduce the weight of the structure, but also meet thermal insulation, sound insulation and other requirements. If a large area needs to be opened or ventilated, facilities such as electric or manual sliding doors or exhaust fans can be used.
In short, the main load-bearing components of the steel structure factory building is the key to ensuring the safe, stable, economical and reliable operation of the factory. During the design and construction process, various factors need to be fully considered to ensure that the load-bearing capacity and stability of the structure meet the requirements.
