Container House Disassembly Atlas

Currently, there is no publicly available complete disassembly atlas for container houses, but their structural logic can be understood through key points of structural disassembly, types of standard drawings, and typical case analyses.

Key Points of Structural Disassembly

Modern inhabited expandable container houses have broken through the simple design of traditional 'iron-skin shells' and formed a complete steel structure system. The main frame is welded from galvanized pipes into a grid-shaped steel skeleton, dispersing loads through beam-column structures, with deformation resistance increased by more than three times compared to single-layer iron sheets. Walls use sandwich-structured thermal insulation sandwich panels, composed of an outer layer of color-coated steel sheets, a middle layer of polyurethane or rock wool insulation, and an inner layer of decorative panels, typically 50-100mm thick, achieving both sound insulation and thermal insulation functions. The floor system includes a moisture-proof baseboard, PVC floor covering, and edge sealing cotton strips, while the roof features a double-layer structure of a ceiling and thermal insulation layer. Windows and doors generally use double-glazed tempered glass, with overall airtightness meeting civil building standards.

Types of Standard Drawings

Drawings for container houses provided by professional design institutions fall into three main categories:

1. Plan, Elevation, and Section Construction Drawings: These mark the original dimensions of 20-foot/40-foot containers (e.g., inner dimensions of a 20-foot container: 5898×2352×2390mm) and the spatial layout after modification, specifying the locations of windows and doors, the routing of water and electricity pipelines, and structural reinforcement nodes.
2. Module Combination Drawings: These show the connection methods for single containers, double-container拼接 (splicing), and multi-layer stacking, including parameters such as corner fitting fixation and bolt spacing, ensuring overall stability meets the standards of 'Construction Details for Modular Steel Structure Housing'.
3. Node Detail Drawings: These refine key technologies such as steel skeleton welding processes, anchoring methods between walls and frames, and fireproof cladding structures. Some drawings will indicate the combustion performance grades of materials (e.g., rock wool panels must meet Class A fire resistance).

Typical Case References

The container residential project in rural Jiangsu used a modified 40-foot high cube container, achieving a 6-meter span by removing side walls and adding steel structural columns, with internal divisions for a living room, bedroom, and separate wet and dry bathrooms. The Danish 9-container residential project retained the corrugated metal inner walls of the containers as decorative elements while adding a 100mm-thick rock wool insulation layer to the exterior walls, maintaining indoor temperatures above 20°C in winter. The construction drawings for these cases include detailed disassembly steps, with technical instructions from foundation treatment to decorative finishes.
