T/ZJNJ 003-2024 Agricultural monomer steel frame greenhouse

Scope

Scope: This document specifies the terms and definitions, general requirements, technical requirements, installation, test methods, acceptance inspection, marking, packaging, transportation, and storage for agricultural single-frame steel frame greenhouse facilities. This document applies to the design, manufacture, construction, and installation of agricultural single-frame steel frame greenhouses, as well as their quality inspection. Improved products may refer to this document for implementation. 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 flexure, vibration, and deformation in the longitudinal and transverse directions, and shall not experience instability under allowable loads, pressures, or thrusts (wind load, snow load, etc.). When locally damaged by 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, shed 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 ≥Level 10 and snow loads ≥150mm thick. 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
