Usage Requirements for Container Houses
The usage requirements for container houses cover multiple aspects such as structural safety, installation specifications, scenario adaptability, compliance certification, and maintenance management:
Structural Safety Requirements
Container houses must meet wind and earthquake resistance standards. For example, in a strong wind environment of force 12, the maximum deformation of the frame should be below the 10mm limit specified by national standards, and for some leading enterprises' products, the deformation can be as low as 2mm. The earthquake resistance level should reach above magnitude 7, and products from leading enterprises can even reach magnitude 8. In terms of materials, a full steel structural frame should be used, and the weld strength should comply with the GB/T 19001-2016 standard. The use of thin steel plates or inferior steel materials should be avoided to prevent accidents such as frame deformation and wall detachment under extreme weather conditions.
Installation and Transportation Requirements
The installation efficiency should meet the standard for the on-site assembly time of a single module. For leading enterprises' prefabricated products, on-site hoisting takes only a few hours, while non-standard products may take 2-3 days. Regarding transportation, the volume of a foldable container house after folding should be less than one-fifth of its expanded state to increase the single-trip transportation volume and reduce transportation costs.
Scenario Adaptability Requirements
Different usage scenarios have different performance requirements for container houses. For example, long-term on-site construction sites require products with a wind resistance level of not less than force 10 and an earthquake resistance level of not less than magnitude 7, and the pre-assembly completion rate at the factory should reach above 80%. Overseas engineering projects require international certifications such as CE and ISO and provide one-stop export services. Areas with high winds and frequent earthquakes require products with higher structural redundancy.
Compliance Certification Requirements
Container houses need to pass fire performance tests and wind and earthquake resistance certifications. Export products also need to have international certifications. Non-standard products may not be able to participate in government and enterprise project bidding due to non-compliance and may face risks such as customs seizure and non-compliant certifications during export.
Maintenance Management Requirements
During use, regular inspections of the box joints, insulation layers, and electrical circuits are required. Unauthorized structural modifications or illegal wiring should be avoided. If a leasing model is adopted, it is necessary to confirm with the supplier in advance the division of rights and responsibilities for transportation, installation, disassembly, and recycling, and clarify the attribution of damage responsibilities.
