Rising ‌Steel structure

First, prefabricated buildings are buildings that are assembled at the construction site after the components are manufactured in the factory. Second, prefabricated buildings are residential buildings with steel as the skeleton and new thermal insulation wall materials as the enclosure structure. As the name suggests, prefabricated steel structure combines the two, that is, a part of the steel structure skeleton is first produced in the factory, and then transported to the construction site by welding, bolts or rivets. Buildings are called prefabricated steel structures.

Because the steel structure itself is light in weight, low in cost, easy to construct, and the assembly is simple and efficient, it has been widely used in factories, venues, stadiums and other buildings from the beginning. What are the characteristics of this combined steel structure?

Compared with traditional buildings, prefabricated steel structure buildings have the following advantages:

Strong elasticity and wind resistance.

Because the prefabricated steel structure is mainly steel, which is an elastic deformation material, and the steel structure itself is light in weight, good in ductility, high in strength, and has strong elasticity and wind and earthquake resistance.

Beautiful environment and short construction period.

Unlike traditional buildings, steel structures have greater plasticity in shape, while prefabricated steel structures use steel as the main body and insulation boards as the fence, replacing traditional non-renewable resources such as bricks, cement, and sand, and are environmentally friendly. Another is that prefabricated steel structure materials are prefabricated in advance in the project, and when they arrive at the construction site, they are connected by workers according to the drawings with welds, bolts or rivets. The whole process is dry work to reduce environmental pollution. Most of the materials are made in the factory, which greatly shortens the construction period.

Insulation.

During the construction process, the combined steel structure wall system adds insulation materials such as European pine boards, cement pressure boards, extruded boards and insulating rock wool, which is equivalent to 10 times thicker brick-concrete walls.

Firefighting.

One of the key issues in the fire protection technology of prefabricated steel structure buildings is that the fire resistance level of steel structure houses must reach level 4. In order to meet the 1-hour fire protection requirements, ordinary fire walls and household walls are protected by gypsum boards. In addition, glass fiber is filled between the columns of the wall and between the floor slabs, which also plays a positive protective role in fire protection and heat transfer.
