T/ZJNJ 002-2018 Fruit tree steel frame netting facility technical specifications
Basic Information
Scope
Scope: This standard specifies the terms and definitions, product technical requirements, installation, test methods, acceptance inspection, packaging, transportation, and storage for fruit tree steel frame netting facilities. This standard applies to the production, installation, and inspection of fruit tree steel frame netting facilities. Its improved products can be implemented in accordance with this standard. Main technical content: The frame skeleton and all its components shall comply with the requirements of this standard and be able to safely withstand all possible load combinations (including constant loads) including wind loads. The design of any dangerous section of components shall not exceed the allowable stress of the steel pipe material. The frame and its components shall have sufficient stiffness and toughness to resist longitudinal and transverse deflection, vibration, and deformation, and shall not experience instability within the allowable load, pressure, and thrust (wind load) range. When subjected to local damage due to external forces, the netting frame structure as a whole shall be able to maintain stability.
