Four major construction points of steel structure engineering

With the continuous development of the construction industry, in many buildings, we can find that most of the buildings have adopted steel structure engineering as the main load-bearing structure, because the steel structure engineering, whether in the shape or in the performance, is higher than the traditional building. However, in the process of steel structure construction, it is easy to have some quality problems, today I will give you a brief introduction.

Cutting of raw materials: Steel structure engineering is to complete the production of components in the factory. The first step in the production of components is to lofting and cutting according to the processing drawings. If the processing quality of the components does not meet the requirements, it will affect the next process and the operation to a certain extent, which will also lead to a discount in the quality of the components, and further affect the quality of the entire building.

Welding process: there are three main connection methods of steel structure engineering, one is welding, the other is bolted connection, and the other is rivet connection, but in the production process of components, welding is the main, the quality of welding is related to the quality of the use of the entire building, so in welding must be full welding, can not miss welding.

On-site installation process: The main feature of steel structure construction is that it is prefabricated, so the installation is an important step in the entire building, and whether the steel structure engineering is stable and firm depends on whether the installation process is correct. Once there is a problem with the installation quality, it is not only easy to cause on-site construction accidents, but also make the quality of the entire project appear large discount, so the quality of the installation is particularly important in the steel structure engineering project.

Anti-corrosion and fire prevention process: The fire resistance and corrosion resistance of steel structure engineering are very poor, so we should pay attention to the coating of fireproof coatings on components and the coating of anti-corrosion coatings during the processing of components. Through the protection of coatings, we can achieve the purpose of anti-corrosion and fire protection. The quality problem of coating is usually the phenomenon of large-area shedding of paint film and the phenomenon of surface flow hanging. There is also the phenomenon of uneven thickness of the paint film, which should be paid great attention to in the process of painting.
