Self-made Container Mobile House

If you want to build a container mobile house by yourself, you need to proceed step by step through four stages: purchase, design, construction, and acceptance, with a focus on core aspects such as structural safety, waterproofing, and material selection.

1. Purchase Stage

Choose the structural type based on the usage scenario:

• Welded Integral Container: Factory-welded as a whole, with a direct load path and strong resistance to deformation, suitable for scenarios requiring frequent lifting and moving (e.g., construction site dormitories).
• Bolted Modular Container: Composed of standard panels connected by bolts. Check the steel wall thickness of the columns and bottom beams (common specifications range from 1.5 mm to 3 mm). Thicker walls provide greater load-bearing redundancy but also increase the self-weight.

2. Design Stage

Plan the layout by combining functional requirements with site conditions:

• Functional Zoning: Clearly define the purpose as residential, office, or commercial, and divide areas such as bedrooms, living rooms, and bathrooms.
• Structural Safety: Ensure that the roof load is transferred through the side wall columns to the bottom beams and then evenly distributed to the ground to avoid excessive local stress.
• Compliance: Consult local planning authorities to confirm the available range of homestead land, building height restrictions, and approval requirements.

3. Construction Stage

Follow standardized procedures to ensure construction quality:

• Steel Frame Welding: Use channel steel or square steel for the chassis welding. The columns and roof ring beams should be fully welded to avoid cold welds.
• Wall and Roof Installation: Use fire-resistant polyurethane sandwich panels or rock wool panels, fill with insulation material, and cover to ensure thermal insulation and fire resistance.
• Plumbing and Electrical Pre-installation: Pre-embed electrical and water supply/drainage pipelines in the walls and floors to avoid damaging the structure with later trenching.
• Waterproofing: Use glass curtain wall waterproof sealant at the roof panel joints. Ordinary sealant has a waterproofing lifespan of only about six months, while glass curtain wall sealant can extend it by 5-6 times.

4. Acceptance Stage

Check whether key indicators meet the standards:

• Structural Stability: Inspect the tightness of bolts to ensure there is no looseness or deformation.
• Waterproof Performance: Conduct a water spraying test to confirm that there are no leaks in the roof and walls.
• Functional Integrity: Test whether lighting, sockets, air conditioners, and other equipment are working properly.
