T/ZJNJ 004-2024 Agricultural steel framed greenhouse with continuous walls

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 multi-span steel frame greenhouses. This document applies to the design, manufacture, construction, and installation of agricultural multi-span 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 critical section of components shall not exceed the allowable stress of the steel tubing materials. The greenhouse and its components shall have sufficient stiffness and toughness to resist longitudinal and transverse deflection, vibration, and deformation, and shall not experience instability under allowable loads, pressures, or thrusts (wind load, snow load, etc.). 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 ≥10 years. All metal structural parts shall adopt necessary anti-corrosion measures, and the corrosion resistance of main components (arch rods, columns, horizontal tie rods, longitudinal tie rods, gutters, etc.) shall be ≥10 years. 3. Load requirements: The greenhouse frame shall adopt a "two-section" structure with arch connectors between two arch rods, meeting the requirements of withstanding wind loads ≥level 10 and snow loads ≥200mm snow thickness. 4. Covering materials: The covering materials shall meet the needs of crop growth in the greenhouse. Use multi-functional agricultural films such as anti-aging and anti-dewdrop polyethylene and EVA with a
