Container House Assembly Explanation

Container house assembly mainly involves stages such as design, manufacturing, transportation, and on-site assembly. It achieves rapid construction through modular and standardized components, offering flexibility, efficiency, and environmental friendliness.

1. Design Phase

Container house assembly centers around modular design, determining container combinations based on intended use (e.g., residential, commercial, office). For instance, expanding interior space by connecting multiple 20-foot or 40-foot standard containers addresses issues like low single-container height and narrow width. Design must balance structural stability with aesthetics, employing adaptive combinations to create unique architectural forms while meeting fire resistance, thermal insulation, and earthquake resistance requirements.

2. Manufacturing Phase

1. Standardized Production: Factories use assembly-line operations to complete tasks such as welding steel frames, prefabricating wall and roof panels, and embedding plumbing and electrical lines. For example, packing-box container houses use hot-dip galvanized cold-formed steel frames paired with fire-resistant polyurethane sandwich panels to ensure thermal insulation and fire safety.
2. Material Selection: Walls commonly use color-steel sandwich panels filled with high-density thermal insulation materials; doors and windows feature sealed designs for enhanced waterproofing; steel structures undergo anti-corrosion treatment to extend service life.

3. Transportation and On-Site Assembly

1. Transportation Convenience: Modular components facilitate easy transportation, enabling rapid arrival at the site and reducing wet work. For example, foldable container houses can be folded for transport and unfolded for assembly, requiring only two people and three minutes to complete the main structure.
2. Assembly Process:
   • Foundation Preparation: Measure wall foundation axis dimensions, ensuring deviations are within allowable limits (e.g., ±25mm), and excavate trenches for foundations (brick or concrete).
   • Frame Construction: Weld steel structures, install square tube columns and steel beams, and adjust verticality with plumb lines to ensure component dimensions meet requirements.
   • Wall and Roof Installation: Lay floors, install wall panels (reserving door and window positions), cover with roof panels, and complete waterproofing.
   • Concealed Works: Plumbing and electrical line embedding, as well as moisture and waterproofing construction, must strictly adhere to specifications to avoid rework.

4. Performance Optimization and Maintenance

Container houses require regular inspection for paint peeling and timely repairs to prevent rust; steel structure joists can be added to the roof and covered with aluminum panels or glass to enhance ventilation and thermal insulation; service life typically ranges from 2 to 30 years, depending on maintenance materials and frequency.
