National Standards for Container Houses

The national standards related to container houses mainly include GB/T 37260.1-2018, CECS334:2013, JGJ/T 469-2019, GB/T51329-2018, etc. These standards regulate the technical requirements for container houses throughout the entire process from design and manufacturing to use.

GB/T 37260.1-2018 'Box-type Light Steel Structure Houses - Part 1: Demountable' is one of the core standards for container houses, focusing on demountable box-type light steel structure houses. This standard specifies design requirements, including calculation methods for structural load-bearing capacity, stability, and wind and earthquake resistance, ensuring the safety of the houses under different environmental conditions. In the manufacturing process, it stipulates the steel material, specifications of connecting components, and processing precision, such as requiring the yield strength of the steel to be no less than 235MPa. During installation, it emphasizes error control in modular assembly, requiring the verticality deviation to not exceed 1/500 of the house height to ensure the stability of the overall structure.

CECS334:2013 'Technical Specification for Modular Combined Container Houses' focuses on modular combination technology, proposing specific requirements for the division of house units and the design of connecting nodes. For example, it stipulates that connecting nodes should use high-strength bolts or welding processes to ensure reliable force transmission between modules. At the same time, this standard also covers the fixing methods during transportation, requiring the use of special straps or supports to prevent module deformation and ensure the efficiency and quality of on-site assembly.

JGJ/T 469-2019 'Technical Specification for Combined Container Houses' and GB/T51329-2018 'Technical Standard for Modular Container Buildings' comprehensively cover material selection, fire resistance, and environmental protection requirements. The former requires the combustion performance of wall materials to be no less than Class B1 and to be equipped with an automatic fire extinguishing system. The latter clearly stipulates that the indoor formaldehyde emission should be less than 0.08mg/m³, meeting green building standards. In addition, these two standards also propose quantitative indicators for the thermal insulation and sound insulation performance of the houses, such as requiring the heat transfer coefficient to be less than 1.5W/(m²·K) to ensure living comfort.

These standards provide a scientific basis for the design, production, and use of container houses by refining technical parameters and construction specifications, promoting the standardization and normalization of the industry.
