Steel Structure Of Glass Greenhouse

1. The steel structure mainly includes the load-bearing structure of the greenhouse and the support, connecting parts, and sturdy components designed to ensure structural stability. 2. Materials and construction precautions: The main materials used for steel structures are cold-formed thin-walled steel and hot-rolled steel. Except for a small number of components that use high-strength steel, all other steels use A3F. The steel framework of glass greenhouses is generally produced by professional chemical factories. Due to the long-term exposure of greenhouse components to indoor high humidity environments, all structural components should undergo anti-corrosion treatment. Usually, hot-dip galvanizing is used for treatment. To ensure the effectiveness of anti-corrosion treatment, all components should be subjected to anti-corrosion operations after processing. Cutting, sawing, welding, and other operations on greenhouse components are not allowed on site. If there are a small amount of on-site operations, anti-corrosion reinforcement treatment should also be carried out on them, and anti-corrosion paint should be sprayed on processing or wounds. The installation of the skeleton should strictly follow the drawings, relevant standards, specifications, and regulations. The industry standard for the main structure of double slope glass greenhouses has been completed in China, and can be used as one of the basis for the construction of steel structures in glass greenhouses after being officially issued. At present, the construction mainly relies on the "GB 50017-2003 Design Code for Steel Structures" and the "GB 50018-2002 Technical Code for Cold Formed Thin walled Steel Structures" as the main construction reference.
3. Design considerations: There is no specific greenhouse design code in China. The design of glass greenhouse steel structures mainly refers to the greenhouse design codes of countries such as the Netherlands (NEN3859, NEN3860), Japan (horticultural facility structural safety standards), and the United States (NGMA). However, in the design, it is necessary to consider issues such as structural strength, structural stiffness, structural integrity, and structural durability.
