T/ZJNJ 003-2018 Agricultural monomer steel frame greenhouse facilities technical specifications

Scope

Scope: This standard specifies the terms and definitions, product technical requirements, installation, test methods, acceptance inspection, marking, packaging, transportation, and storage for agricultural single-frame steel greenhouse facilities. This standard applies to the production, installation, and inspection of agricultural single-frame steel greenhouses. Its improved products can be implemented in accordance with this standard. Main technical content: 1. Safety and stability: The greenhouse structure and all its components shall comply with the requirements of this standard, and be able to safely withstand all possible load combinations (wind load, snow load, etc.), including dead loads. The design of any dangerous section of components shall not exceed the allowable stress of the steel pipe material. The greenhouse and its components shall have sufficient stiffness and toughness to resist longitudinal and transverse deflection, vibration, and deformation. They shall not lose stability within the allowable load, pressure, and thrust (wind load, snow load, etc.) ranges. When subjected to local damage due to external forces, the greenhouse structure as a whole shall maintain stability. 2. Durability: The service life of the greenhouse frame shall be ≥8 years. All metal structural parts of the greenhouse shall adopt necessary anti-corrosion measures, and the corrosion resistance time of main components (arch rods, greenhouse head columns, longitudinal rods, diagonal braces, arch rod connectors, etc.) shall be ≥10 years. 3. Load requirements: The "two-section" structure using arch rod connectors between two arch rods in the greenhouse frame shall meet the requirements of withstanding wind loads ≥10 grades and snow loads ≥150mm snow thickness in the greenhouse as a whole. 4. Covering materials: The covering materials shall meet the needs of crop growth in the greenhouse. Multi-functional agricultural films such as anti-aging and anti-fog polyethylene and EVA wit
