Quality inspection process of prefabricated steel warehouse

Steel structures are widely used in high-rise buildings, large-scale factory warehouses and other fields. It is conceivable how strong and reliable its quality is. Process technology is also inseparable from the silent efforts of quality inspectors. Many people may be curious about the job responsibilities of quality inspectors, and what is their quality inspection process? So today, Xiaobian will take you to understand how the quality inspection process of prefabricated steel warehouse is.

Every prefabricated steel warehouse project undertaken by the steel structure company will be strictly checked and approved by the relevant departments of the company and the quality inspection personnel. When the quality inspection personnel inspect in the factory, whether it is cutting and blanking, hole making and welding, or grinding and painting Etc., each process will have a trusted inspection standard to ensure that the steel structural components are qualified without errors and damage when they leave the factory.

Before the on-site construction, the quality inspectors of the steel structure company will first check the length of the bolts left by the embedded parts on the construction site (the bolts protrude from the support surface by 3cm, and the thread leaks out by 3cm, which is qualified), and the foundation elevation (the error is within plus or minus 5mm). Whether the distance between the steel columns meets the installation requirements of the drawings, and the relevant inspection meets the installation requirements and records are recorded, the steel structure components will enter the construction site for construction and installation.

During on-site construction, the quality inspectors of the prefabricated steel warehouse will check whether the steel structure components are tilted or data deviations during assembly. This involves construction processes such as initial tightening, re-twisting, and final tightening of high-strength bolts. Check the condition of the components, and also observe whether the construction and installation personnel operate in accordance with the prescribed installation steps. If the construction and installation personnel do not follow the steps, the inspectors should persuade and prevent them in time.

Of course, in addition to checking these, the quality inspector should also check the composition of the steel structure, whether there are collisions, dents, paint peeling, etc., if there is a similar situation, the quality inspector should contact the company in time. After the steel structure is installed and passed the acceptance process (acceptance is divided into 1. Acceptance by the customer and the constructor 2. Acceptance by the government), the quality inspection process of the prefabricated steel warehouse also ends.
