Interior Partition Design for Container Houses

The interior partition design of container houses requires comprehensive consideration of structural safety, functional suitability, and fire protection regulations. Common solutions and key considerations are as follows:

I. Common Partition Structure Solutions

1. Light Steel Keel Partition System
   Using calcium silicate cement board as the base layer and covered with decorative panels (such as bamboo-wood fiberboard, wood veneer, etc.), it is suitable for container houses, mobile houses, and other scenarios. Its core advantage is lightweight and high strength (bulk density approximately 0.8-1.2 kN/m³), which can avoid overloading the container structure due to the addition of partitions.

2. Composite Structure Combination

   • Solution 1 (Residential Type): From outside to inside, it consists of metal paint → galvanized corrugated board → polyurethane foam (optional) → thermal insulation rock wool → steel keel → bamboo-wood fiberboard. This solution balances thermal insulation and decoration, suitable for bedrooms, bathrooms, and other areas.
   • Solution 2 (Office/Commercial Type): Metal paint → galvanized corrugated board → polyurethane foam (optional) → thermal insulation rock wool → steel keel → woodworking board/OSB board base layer → gypsum board base layer → local anti-rust paste → latex paint. This structure can meet the needs of network cabling and is suitable for open office areas or tea rooms.

II. Key Design Considerations

1. Structural Safety

   • Prioritize the use of lightweight materials (such as light steel keel + gypsum board) and avoid using heavy materials like concrete.
   • When connecting the partition to the original steel columns of the container, reinforcement with square tubes (e.g., 80×80×3mm or 100×100×4mm) is required to ensure that openings (windows, doorways) are positioned away from the steel columns.

2. Fire Protection Requirements

   • Interior decorative materials must meet or exceed Class B1 (flame-retardant) standards. The use of flammable materials such as polystyrene foam boards is strictly prohibited.
   • Electrical wiring must be protected by metal conduits, and fire-resistant partitions should be installed around sockets and switches.

3. Ventilation and Lighting

   • Residential houses must be equipped with windows (area ≥ 1/10 of the floor area) or mechanical ventilation systems (air exchange rate ≥ 2 times per hour).
   • Office houses are recommended to use double-glazed windows to balance sound insulation and lighting.

III. Functional Suitability Recommendations

1. Residential Type

   • For bedroom walls, environmentally friendly latex paint is recommended, and the floor should be laid with laminate flooring (thickness 8-12mm).
   • Bathrooms require waterproofing treatment (height ≥ 1.8m) and reserved drainage slopes.

2. Office Type

   • Open office areas need to be pre-embedded with Category 5e or Category 6 unshielded network cables, and conference rooms need to be equipped with projector interfaces.
   • Tea rooms need to reserve water supply and drainage pipes and install splash-proof sockets.

3. Commercial Type

   • Coffee shops need to design a bar counter (height approximately 1.1m), display shelves (depth 0.4-0.6m), and have no fewer than 8 power sockets.
   • Retail stores need to consider shelf load-bearing (steel shelves are recommended) and set up interfaces for anti-theft alarm systems.

IV. Industry Standard Basis

The design must strictly comply with the Technical Specification for Container Houses (CECS 334:2013) and the Code for Fire Protection Design of Interior Decoration of Buildings (GB 50222-2017) to ensure structural safety and fire protection compliance.
