Industrial prefab steel structural multi storey warehouse building

Quality control points for steel structure engineering:

1. Pre embedded anchor bolts: The embedding quality of anchor bolts directly affects the installation quality of steel structure engineering. The position, verticality, length, and height of anchor bolts (groups) should be well controlled, which can reduce the workload of reaming and adjustment (even avoid rework), and improve structural installation. Quality is of great significance. The method of pre embedding anchor bolts can be direct pre embedding method or reserved hole method. Before pouring foundation concrete, the supervising engineer should strictly check the correctness and correctness of the embedded bolt construction method, as well as whether the measured indicators are within the specified range of the specifications.

2. Welding engineering quality control: Welding engineering is one of the important sub projects in production and installation engineering. The supervising engineer participates in the preparation, welding process, and finished product inspection processes, and controls the quality of welding engineering. At present, most construction units are equipped with automatic submerged arc welding machines, and some even have semi-automatic gas shielded welding machines. Some parts are only welded manually.
