Steel structure factory building refers to the internationally popular portal steel frame light steel structure system that is made of steel plates and hot-rolled, cold-formed or welded profiles connected through connectors that can withstand and transmit loads.
Use light H-shaped steel (welded or rolled; variable cross-section or equal cross-section) to make the portal-shaped steel frame support, C-shaped and Z-shaped cold-formed thin-walled steel as purlins and wall beams, profiled steel plates or lightweight sandwich panels as The roof and wall enclosure structure is a portal steel frame steel structure system assembled with high-strength bolts, ordinary bolts, self-tapping screws and other connectors and sealing materials. Steel structure factory buildings are more reasonably and widely used around the world, especially in the field of steel structure construction engineering in developed countries and regions. Steel structure workshops can be widely used in industrial plants, purification workshops, storage warehouses, supermarkets, and exhibition halls.
Steel structure factory buildings have the following characteristics:
1. The steel structure factory building is light in weight, and the weight of the steel structure is only one-fifth of the brick-concrete structure. The steel structure factory building has high strength, large span and large space.
2.The steel structure factory building has good earthquake resistance and impact resistance. The steel structure factory building has good overall rigidity and strong deformation ability.
3. The steel structure factory building has high fire resistance, high corrosion resistance and high sealing performance.
4.Steel structure factory buildings have low investment, are easy to demolish, can be recycled multiple times, are environmentally friendly and have long structural life.
5. The steel structure factory building has a high degree of industrialization and can be quickly installed on standard assembly lines.
6. The steel structure occupies a small area and has a large usable area. It increases the usable area by 4%-8% compared with traditional concrete structure buildings, which indirectly increases economic benefits.
7. The steel structure factory building is easy to modify during use, such as reinforcement, height connection, partition and other internal divisions. It is relatively easy to adjust, flexible and convenient.
The steel structure factory building structure is mainly divided into five parts:
1. Foundation embedded parts (can stabilize the steel structure factory building structure)
2. Columns are made of H-shaped steel, I-beam, round pipe or C-shaped steel (two C-shaped steels are butted together)
3. Beams are made of C-shaped steel and H-shaped steel.
4. Purlins usually use C-shaped steel and channel steel.
5. The walls and roofs are made of color steel profiled plates, one is color steel single piece tiles (color steel tiles). One is color steel sandwich composite panel. Foam, rock wool, glass wool, polyurethane, etc. are placed between the two layers of tiles to achieve fire retardant, sealing, and sound insulation effects.
