How to control the quality of steel structure building

The links that affect the quality of steel structural components in the manufacturing stage include: component material selection and inspection, component processing technology and manufacturing quality inspection. Material selection and inspection are directly related to the quality of component materials. No matter how reasonable the processing technology is, it is impossible to produce qualified steel components with unqualified materials. There are many technological processes involved in the production of steel structure components. Each technological step of steel component production affects the processing quality of steel components. Strict control of each production process can only.. The processing quality of steel components, and the quality of the processing and production stage, the stage of strict and detailed quality inspection, these quality inspection throughout the processing and production of all process steps.

There are many steel structure construction and installation methods, using different construction and installation methods, the structure in the construction process and completion of the internal force and deformation state may be different, excessive deformation and unreasonable internal force state not only affect the installation quality of the structure, but also affect the safe use of the structure.

In addition, the connection quality of steel components in the installation process (including welding connection, bolt connection, tapping screw, etc.), component splicing accuracy, component deformation or damage, node plate position and size, component surface quality, etc., all directly affect the steel structure installation quality, only.. The quality of each link in the installation process can.. Whole building installation quality. The means of installation quality is the quality inspection in the installation process. Similarly, the quality inspection in the installation process also runs through the entire installation process, especially the installation quality inspection of hidden works or hidden parts, which should be paid special attention to.
