Industrial prefab steel structural multi storey warehouse building

Why is industrial prefabricated steel structure multi-layer warehouse building popular among the public? It still has many advantages:

1. Due to the good construction efficiency of industrial prefabricated steel structure multi-layer warehouse buildings, the walls are made of lightweight and standardized C-shaped steel, square steel pipes, and color steel sandwich panels, which have good thermal insulation characteristics and good grade.

2. Because the construction of industrial prefabricated steel structure multi-storey warehouse buildings is more satisfactory than traditional construction, the regulations for flexible and deep separation in construction can be improved, and the total cross-sectional area of columns can be reduced and lightweight partition panels can be used to develop the total area application rate. The total indoor application area can be developed by about 6%.

3. If the steel frame structure system software is used for residential construction, it can fully utilize the good ductility and plastic deformation working ability of the steel frame structure, and have excellent grade wind resistance. Especially in the event of earthquake or storm disasters, steel frame structures can prevent collapse damage to buildings.

4. Because the total weight of steel frame structure construction is light, the weight of the steel frame structure residence system software itself is about half of that of reinforced concrete, which can reduce the basic engineering cost.

There are still some technical deficiencies in the promotion of industrial prefabricated steel structure multi-storey warehouse buildings and residential buildings. This refers to technical problems, which include many comprehensive problems. From the design, structural prefabrication, installation, internal layout, and supporting fences of buildings, these technologies are still in the development stage and are not mature. It is difficult for us to find a balance point between economy and technology. Additionally, there is a lack of domestic technical personnel. Most construction personnel have no experience in constructing industrial prefabricated steel structure multi-storey warehouse buildings and residential buildings. Compared to concrete buildings, the construction technology requirements for industrial prefabricated steel structure multi-storey warehouse buildings in Xinjiang are not high. In addition, there are too many migrant workers in China who can handle them. However, the construction of industrial prefabricated steel structure multi-storey warehouse buildings requires technical expertise from all participating personnel. Good training.

The prefabricated components and assembly of steel components shall be carried out on the platform of the industrial prefabricated steel structure multi-layer warehouse building in accordance with the installation sequence and processing technology regulations, and the quality shall be produced by electric welding. The spacing between the splice joint of the flange plate of the channel steel and the splice joint of the beam end should exceed 200mm. The length of the flange plate splicing should not be less than twice the plate width; The total width of beam end splicing shall not be less than 300mm, and the length shall not be less than 600mm. In order to ensure the convenience and quality of electric welding, it is necessary to carry out verification welding on the steel structure of the road surface, as well as on the reinforcement plates, connecting plates, cushion blocks, and cantilever beams (beams) on the multi story warehouse building platform of the prefabricated steel structure according to the construction drawing specifications as much as possible.

The awareness of domestic design units adopting the form of industrial prefabricated steel structure multi story warehouse buildings for residential purposes is insufficient. Buildings using industrial prefabricated steel structure multi story warehouse buildings as the main framework are generally considered too expensive and the technology is relatively immature in China. There are many shortcomings that existing technology cannot compensate for. Therefore, most buildings still choose conservative concrete or precast concrete components to build residential buildings. This environment has led to a slow development of industrial prefabricated steel structure multi story warehouse buildings. Therefore, the development of industrial prefabricated steel structure multi story warehouse buildings is not only a technical problem, but also requires the concept of the entire building to keep up with the times. We need to continuously advocate and improve the current construction concept of conservative buildings, gradually developing into the construction system of industrial prefabricated steel structure multi story warehouse buildings.
