How can the installation quality of steel structure plant meet the standard?

1. The steel components of the steel structure plant shall first be processed and produced in accordance with the requirements of the construction drawings. The processing and production of all steel components should meet standards and regulations to improve the quality of components of steel structure plants. Secondly, protective measures should be taken during the transportation of steel components, and protective measures should be taken to avoid damaging the coating and surface during the stacking process.

2. Most structural steel is made of section steel. Much of the steel was H-shaped, including many other steels at the time. The choice of steel also depends on the needs of the owner, but all steel components should have the corresponding factory qualification certificate to ensure the quality of the steel components.

3. The steel structure plant should be prepared for the construction before installation, and all steel components should be reinspected and installed after confirmation. Confirm that there is no deformation and splitting of the steel member before hoisting, and the hook can be sent after hoisting in place. The installation of steel structure plant should be gradually supported. After lifting the steel column, the axis and elevation should be re-tested, and the error should be corrected in time. After correction, the steel column can be stabilized by cable wind rope, and then the intercolumn supports, roof beams and interbeam ties are installed.

4. In the installation process of the steel structure plant, a stable structure should be formed as soon as possible, which is a stable structure of the entire plant interval, so that the cumulative error generated in the installation process of the entire plant is dispersed to each part, forming the stability of the entire structure. The steel column and steel beam between each rack should be measured and corrected independently and cannot be used as a benchmark to ensure that the installation of the steel structure plant can meet the requirements.

5. All temporary fixed bolt holes that need to be welded on site should be designed with long holes for easy installation and adjustment, and more conducive to ensuring the overall installation accuracy. Purlins and other members of the unilateral connection holes should also be designed long holes. Of course, the relevant gaskets should also be increased accordingly. The installation steps of the steel structure plant are carried out according to the construction drawings, and the installation quality is guaranteed.
