Precautions for Container Houses
When using container houses, it is essential to focus on aspects such as the rationality of structural design, material quality, fire and wind resistance, ease of assembly and disassembly, and compliance with regulations. Here are some specific precautions:
1. Structural Design Should Be Suitable for the Usage Scenario
According to the 'Building Structural Design Code', the frame structure of container houses must meet stability requirements. For example, in earthquake-prone areas, reinforced frames should be used, and in areas with strong winds, wind-resistant designs should be strengthened. For long-term residential or office scenarios, more rigorous structural designs are necessary to prevent wall cracking or door and window deformation due to frame deformation. If used for temporary exhibitions or emergency rescue, priority should be given to double-wing expansion structures with strong space expansion capabilities to ensure maximum space utilization after expansion.
2. Material Quality Should Meet Safety and Environmental Standards
Steel and insulation materials should comply with the 'Building Material Quality Standards'. For example, the core material of sandwich panels must be Class A non-combustible material (such as rock wool or glass wool), and the use of flammable EPS polystyrene foam is strictly prohibited. The wall thickness of steel is recommended to be no less than 2.3mm, and the load-bearing redundancy of columns and bottom beams should be sufficient. Additionally, the coating process on the surface of the container body should be inspected; hot-dip galvanizing is more corrosion-resistant than cold-dip galvanizing, especially suitable for areas with large temperature differences between day and night and significant humidity changes.
3. Fire and Wind Resistance Should Meet Standards
The fire rating of container houses should reach Class B1 or above, and the use of flammable materials should be avoided. For example, welding operations should be kept away from the container body, and metal pipes should be equipped with high-temperature-resistant sleeves; open-flame equipment such as heating stoves should be equipped with fire protection facilities. In terms of wind resistance, fixing devices should be installed at the bottom to prevent movement or overturning caused by winds of magnitude 8 or above; in coastal areas, products with a wind resistance rating of magnitude 8 or above should be selected to prevent frame deformation or wall cracking.
4. Assembly and Disassembly Should Be Convenient and Efficient
Prefabricated assembly products should be prioritized, as on-site hoisting can be completed in just a few hours, significantly reducing time costs. For example, foldable containers can be folded to 1/5 of their expanded volume, increasing single-trip transportation volume by 60% and reducing transportation costs by 25%. If frequent relocation is required (such as for construction site dormitories or wilderness camps), it is necessary to ensure that the components of the container body are firmly connected to prevent overall stability from decreasing due to loose bolts.
5. Compliance with Regulations and After-Sales Service Should Be Comprehensive
It is necessary to check the product's fire detection report, wind and earthquake resistance certification, and environmental protection material certificate to ensure compliance with the 'Modular Temporary Building Safety Code'. Export products should have international certifications such as CE and ISO to avoid customs seizure risks. Additionally, manufacturers should provide a nationwide after-sales service network with a response time of no more than 24 hours to avoid project stagnation due to delayed maintenance.
