[0002] The air film dome warehouse adopts a three-center spherical vault warehouse structure, which changes the dome's vector-radius ratio from the traditional 0.5:1 to 0.35:1, thereby reducing 1 / 3 of the invalid space and greatly reducing the operating energy consumption. In addition, its dome structure has good mechanical properties, can adapt to large loads, has strong earthquake and wind resistance, and its mechanical properties are better than the shallow circular silo cone structure. It has been widely used in industrial material storage, grain storage, commercial and civil housing and other fields.

The operator cleans the inner surface of the air film, sprays polyurethane, ties steel bars, sprays concrete, and measures and lays out lines in the hanging basket. For cranes, the stability is relatively low, and the requirements for roads and sites are high.
