Special-Shaped Container House Production

The production of special-shaped container houses requires a combination of structural design, material selection, and modular construction techniques. The core process covers design deepening, frame processing, enclosure system installation, and on-site assembly, with a focus on mechanical stability, precision in processing irregular curved surfaces, and thermal insulation performance.

1. Design Phase: Integration of Non-Standard Structures and Functions

The design of special-shaped container houses necessitates breaking away from traditional rectangular frames, utilizing parametric modeling tools (such as Rhino+Grasshopper) for surface optimization to ensure that the distribution of stress points on the shell conforms to mechanical principles. For instance, the Birdcage House achieves a natural curved form through modular assembly of a lightweight steel frame and metal panels, while also requiring finite element analysis (FEA) to verify structural stability and avoid stress concentration issues caused by irregular curved surfaces. The design phase also involves reserving space for pipeline embedding and planning the positions of openings such as doors, windows, and balconies to ensure a balance between functionality and aesthetics.

2. Frame Processing: Steel Selection and Welding Techniques

The main frame typically employs hot-dip galvanized cold-formed steel or lightweight steel joists, with a yield strength meeting the Q345 standard to withstand wind pressure and seismic loads. The processing of irregular components requires CNC cutting equipment to ensure that the precision error of curved surfaces is controlled within ±2mm. The welding process must utilize full-penetration welding, and weather-resistant sealant should be applied at the joints to prevent rainwater leakage. For example, a manufacturer in Xian County achieved an IP65 waterproof rating for irregular container bodies through continuous welding combined with weather-resistant sealant in a water spray test.

3. Enclosure System: Integration of Insulation and Decoration

The external cladding material can be metal profiled sheets or special composite materials, with polyurethane or rock wool insulation layers filled inside, the thickness of which should be adjusted according to the climate zone (≥80mm recommended for cold regions). The wall decoration layer can be made of ecological wood-plastic panels or aluminum panels, installed using a snap-fit method for rapid construction. For example, a project in Nanjing adopted thickened fire-resistant rock wool with tin foil wrapping, improving the thermal insulation performance of the temporary building by 30% while meeting Class A fire resistance requirements.

4. On-Site Assembly: Modular Lifting and Commissioning

After the factory completes the installation of the main structure, utilities, and interior finishes, the components are transported to the site in modules. Assembly requires the use of lifting equipment for precise lifting and high-strength bolts for frame connection. During the commissioning phase, the tightness of doors and windows, the safety of the electrical system, and the smoothness of water supply and drainage must be checked to ensure that the house meets delivery standards.
