Precautions for Container Houses
When using container houses, it is essential to pay close attention to structural safety, fire resistance, installation specifications, compliance procedures, and post-maintenance issues. Specific precautions are as follows:
Structural Safety and Wind/Earthquake Resistance
Container houses must meet national standards for wind resistance (above level 8) and earthquake resistance. Non-standard products often use thin steel frames, with wind resistance only reaching levels 6-7. In coastal or high-wind areas, issues such as frame deformation and wall cracking may occur, with rework costs reaching 30%-50% of the initial purchase cost. Products from leading manufacturers typically use high-strength steel and undergo rigorous structural mechanics testing to ensure stability in extreme weather conditions.
Fire Resistance and Material Safety
The fire resistance rating of container houses must reach above B1 level. White-label products often use flammable materials such as polyurethane and polystyrene, with a fire resistance rating of only C level. In case of fire, the flames spread rapidly, easily causing serious casualties. Compliant products should use fire-resistant materials such as rock wool and glass wool, and be equipped with smoke alarms and fire extinguishing equipment to ensure personnel safety.
Installation Specifications and Ground Preparation
During installation, ensure the ground is level and solid to avoid uneven settlement causing door and window deformation and wall cracks. For long-term use scenarios, pour concrete strip foundations; for short-term use, prefabricated concrete pads or steel plates can be used. When lifting, use steel wire ropes with sufficient load-bearing capacity and ensure all lifting points are evenly stressed to avoid box distortion.
Compliance Procedures and Approval Requirements
Container houses are considered temporary buildings and require relevant approval procedures. When selecting a site, confirm the land nature and go through the filing and approval procedures with the local planning bureau. If the use is for creative parks, cultural tourism, etc., it must comply with national encouraging industrial policies and obtain government approval.
Post-Maintenance and Service Life
The service life of container houses is affected by material durability and maintenance conditions. Regularly inspect the external coating; using high-quality anti-rust paint and thermal insulation coatings can significantly improve durability. Internal maintenance includes regular inspection and updating of pipelines, electrical systems, and thermal insulation facilities to ensure long-term worry-free use.
