Construction Site Container House Practices

The practices for constructing container houses at construction sites mainly include steps such as purchasing, ground treatment, main structure construction, interior decoration, and installation of supporting facilities:

1. Purchasing Stage:

   • Selection of Structural Type: Choose between welded integral containers and bolt-connected assembled containers based on needs. Welded containers have strong integrity and are suitable for frequent movement; assembled containers are easy to disassemble and assemble, making them suitable for multiple turnovers.
   • Inspection of Steel Specifications: Pay close attention to the wall thickness of the steel used for columns and bottom beams. Common specifications range from 1.5 mm to 3 mm. Thicker walls result in stronger load-bearing capacity but also increase the self-weight.
   • Selection of Coating Process: Prioritize hot-dip galvanizing, which has a significantly longer anti-corrosion lifespan than cold-dip galvanizing, especially in areas with large temperature differences between day and night and significant humidity changes, effectively delaying rusting of the container body.

2. Ground Treatment:

   • Foundation Construction: After removing loose soil and debris from the ground, compact the original soil layer. For long-term fixed use, pour a concrete strip foundation with a recommended width of 30 cm to 50 cm and a depth determined by the local frost depth to ensure uniform load-bearing.

3. Main Structure Construction:

   • Welding of Steel Framework: Use channel steel and square tubes to weld the chassis and columns, forming a light steel framework. For example, the chassis crossbeams use 4×8×2.0 square steel with a spacing of 35 cm, and the columns and roof ring beams are fully welded with 5×5×2.0 square steel.
   • Installation of Wall and Roof Panels: Use rock wool sandwich panels, cleanroom panels, and other materials to拼接 (assemble) wall and roof panels. A double-sided white design enhances aesthetics. The roof panels need to be sealed with glass curtain wall waterproof adhesive to ensure long-lasting waterproof performance.

4. Interior Decoration and Installation of Supporting Facilities:

   • Ground Treatment: Lay high-grade floor leather to enhance warmth and cleanliness.
   • Water and Electricity Installation: Install lighting fixtures, switches, sockets, and air conditioning holes according to regulations, reserving positions for air conditioning pipelines.
   • Door and Window Installation: Use specially made color steel plate doors and sliding windows, install anti-theft nets, and apply waterproof adhesive to ensure safety and airtightness.

5. Post-construction Maintenance:

   • Rust Prevention: Regularly inspect welds, corners, and other areas. If rust spots are found, grind and repaint them promptly. The repainting cycle should be adjusted according to environmental humidity.
   • Waterproof Sealing: Replace the sealant around doors and windows and at container body joints every 5-7 years. Clean fallen leaves from the roof to prevent water accumulation and corrosion.
