Precautions for Using Container Houses

When using container houses, it is essential to focus on structural safety, fire prevention, rust prevention, compliant use, and daily maintenance:

1. Structural Safety

• Purchase Stage: Prioritize welded integral containers (high resistance to deformation) or bolt-connected assembled containers (check the wall thickness of the steel columns and bottom beams, recommended 1.5-3 mm; thicker walls provide greater load-bearing redundancy).
• Installation Foundation: The ground must be leveled and compacted. For long-term use, it is recommended to pour a 30-50 cm wide concrete strip foundation, with a top surface height difference not exceeding 5 mm. For short-term use, prefabricated concrete blocks or steel plates can be used, with a spacing not exceeding 2 meters.
• Lifting and Positioning: Use steel wire ropes with sufficient load-bearing capacity to ensure that all lifting points are synchronized in force application, avoiding unilateral force that could cause container distortion. After positioning, check the fit between the bottom beam and the foundation, with a levelness error controlled within 2 mm per meter.

2. Fire Prevention Measures

• Material Selection: Avoid using flammable materials such as polyurethane and polystyrene for filling the panel cores; prioritize fire-resistant materials like rock wool.
• Open Flame Management: Prohibit open flame operations such as welding inside the container. Heating stoves must be equipped with fire safety equipment, and activities like barbecuing and setting off fireworks near the container should be minimized.
• Electrical Safety: Install electrical circuit isolation devices to prevent cables from directly contacting light steel components. The use of high-power appliances like induction cookers is strictly prohibited.

3. Rust Prevention Treatment

• Coating Process: Choose hot-dip galvanizing (longer corrosion resistance than cold-dip galvanizing), especially in areas with significant temperature variations between day and night and humidity changes.
• Regular Maintenance: Inspect the container's welds, movable joints, and door and window fittings. In cases of severe rust, remove the rust, perform weld repairs, and apply anti-rust oil. If panel bending or deformation is detected, repair or replace it promptly.

4. Compliant Use and Approval

• Functional Restrictions: Do not擅自 (unauthorized) change the original designed use function (e.g., converting a dormitory into a warehouse). The floor load should not exceed the design value.
• Approval Procedures: For long-term residence, follow local requirements to obtain building approval and provide structural drawings. For leased land, use is limited to temporary purposes, and the contract must clearly specify the nature of use.

5. Daily Maintenance and Management

• Regular Inspections: Establish management systems for security, fire safety, and health and epidemic prevention. Inspect and reinforce the container structure before the arrival of rain or snow.
• Component Maintenance: Regularly inspect the welds of load-bearing frames and movable joints of components. Replace damaged doors and windows promptly.
• Environmental Management: Prohibit the storage of flammable and explosive materials in living areas. Regularly clear debris and keep passageways clear.
