Simple Container House Structure Diagram

The structure of a simple container house (expandable residential container) centers around a steel frame, complemented by sandwich walls, multi-layer floors and ceilings, and double-glazed windows and doors, forming a stable and livable residential system that is fundamentally different from traditional iron-sheet container houses. Specific structural features are as follows:

1. Steel Frame Structure: High-Strength Load-Bearing System
The main frame employs galvanized pipe welding technology, with cross-bracing between intermediate beams and columns to form a grid-like load-bearing structure. This design significantly enhances overall resistance to deformation, enabling it to withstand substantial loads (such as multi-layer stacking or severe weather conditions), and avoids issues like shaking and air leakage caused by the thin frame of traditional iron-sheet containers. The corrosion resistance of the steel frame also extends the service life of the house, making it suitable for long-term residential use.

2. Sandwich Walls: Integrated Sound Insulation and Thermal Insulation
The walls are constructed using thermal insulation sandwich panels, consisting of two layers of metal sheets (such as color-coated steel sheets) sandwiching an insulation material (such as polystyrene or rock wool). This structure not only addresses the drawbacks of traditional containers, which are “cold in winter and hot in summer,” but also effectively blocks external noise through the damping effect of the metal sheets and the air layer in the insulation, enhancing residential comfort. The modular design of the sandwich panels also facilitates quick assembly and replacement.

3. Multi-Layer Floors and Ceilings: Dual Optimization of Moisture Resistance and Thermal Insulation

• Floor System: Adopts a three-layer structure of “base plate + floor covering + bottom cotton strip.” The base plate serves as a moisture barrier, the floor covering provides a flat surface, and the bottom cotton strip further isolates ground moisture, preventing the condensation issues found in traditional container floors.
• Ceiling System: Comprises a ceiling and a thermal insulation layer. The ceiling is typically made of lightweight panels, while the thermal insulation layer uses high-density foam or rock wool to reduce heat transfer through the ceiling, lowering indoor temperature fluctuations in summer.

4. Double-Glazed Windows and Doors: Energy Efficiency and Safety Combined
Windows and doors are made of double-glazed units with inert gas (such as argon) filled between the glass panes, forming an efficient thermal insulation layer. Sealed with weatherstripping, they further reduce heat loss. The laminated glass design enhances impact resistance, ensuring that even if broken, the glass will not scatter, improving safety. Some high-end models are also equipped with thermal break aluminum profiles to further block thermal bridging effects.

Structural Comparison Summary
Traditional iron-sheet containers consist of a single layer of thin iron sheet enclosing a simple frame, suffering from issues like air leakage, shaking, and poor thermal insulation. In contrast, expandable residential containers achieve the goals of structural stability, residential comfort, and long-term usability through the combination of steel frames, sandwich panels, multi-layer protection, and double-glazed windows.
