The process of Sichuan steel structure engineering is no longer simple

In the construction process of Sichuan steel structure engineering, each link is related to each other, and the poor control of one link will affect the overall effect of a good structural building. Today, I will introduce you to the construction process of Xirong steel structure in the steel structure installation link.

1. Before the installation of steel structure, the quality of steel structure components should

be inspected, the deformation and defects of steel components should not exceed the allowable deviation, and the measurement and correction of steel component installation should be carried out according to the characteristics of Sichuan steel structure engineering. The main process of welding of thick steel plate and dissimilar steel plate, high-strength bolt installation, should be tested before installation, and the corresponding construction process should be compiled.

2. When Sichuan steel structure engineering adopts an enlarged assembly unit for installation, the strength and stability of the steel components that are easy to deform should be calculated, and reinforcement measures should be taken if necessary; When the steel components are comprehensively installed, they should be divided into several independent units, and after all the steel components of each unit are installed, a spatial rigidity unit should be formed.

3. After the main components of the steel structure, such as columns, beams, roof trusses, and supports, are installed in place, they should be corrected and fixed immediately. The steel components installed on the same day form a stable space system. When installing and correcting steel structure, corresponding adjustment measures should be taken according to the influence of external environment such as wind, temperature difference, sunshine and welding deformation;

4. When using the installed steel structure to lift other components and equipment, the consent of the design unit should be obtained, and the calculation should be carried out and corresponding measures should be taken.

5. The design requires the top tightening node, and 70% of the contact surface should be closely followed. Check with a 0.3mm thick feeler gauge, the sum of the insertable areas shall not be greater than 30% of the total area of contact top tightening; The maximum clearance of the edge should not be greater than 0.8mm;

6. When installing high-strength bolts, the bolts should freely penetrate into the hole and should not be used as temporary installation bolts. The installation of high-strength bolts should be tightened in a certain order, which should be tightened outward from the center of the bolt group, and should be completed by the end of the day.
