Container House Decoration Site

At the container house decoration site, it is essential to focus on structural stability, decoration integration, water and electricity connections, and thermal and sound insulation treatments. The specific key points are as follows:

Structural Stability and Foundation Treatment

Container houses are primarily structured with steel frames, and it is crucial to ensure that the welding or bolt connection strength of the frames complies with building seismic design codes (e.g., GB50011-2010). Before on-site assembly, the flatness of the foundation must be checked. If pile foundations are used (e.g., in forested or mountainous areas), it is necessary to ensure that the connection between the container and the pile is secure to prevent structural deformation due to foundation settlement. For example, in one case, the container was mounted on piles without ground contact, providing both moisture and thermal insulation, but strict control over pile bearing capacity was required.

Decoration Integration and Modular Construction

Most container houses have undergone internal decoration in the factory, including wall, floor, bathroom fixtures, and pipeline embedding, requiring only lifting and assembly on-site. If secondary decoration is needed, attention should be paid to the following:

• Spatial Layout: Fixed dimensions (e.g., 3 meters × 6 meters) limit large-space design, necessitating the adoption of functional overlay strategies, such as concentrating the kitchen and bathroom as wet areas, and using convertible furniture (e.g., folding tables, drop-down beds) in the living and sleeping areas to achieve day-night functional switching.
• Decoration Materials: Priority should be given to lightweight and fire-resistant materials to avoid increasing the structural load. For example, PVC-clad steel plates can be used for the inner layer to reduce thermal radiation, and rock wool can be filled in the walls to enhance thermal insulation.
• Joint Treatment: The joints between containers should be treated with sealing strips to prevent rainwater leakage and thermal bridge effects, with particular attention to the airtightness of doors, windows, and walls.

Water and Electricity Connections and System Integration

On-site, rapid connection of water and electricity pipelines is required, and system stability should be tested:

• Water and Electricity Embedding: Pipeline embedding has been completed in the factory, and only the main lines need to be connected on-site. The sealing of the interfaces should be checked to prevent water and electricity leakage.
• Extended Systems: Depending on requirements, systems such as solar photovoltaic power generation, rainwater collection, and septic tanks can be integrated. For example, in one case, solar panels were installed on the roof to achieve self-sufficiency in electricity, combined with triple-glazed windows (with better thermal insulation than red brick walls) and internal thermal insulation layers, forming an independent ecological cycle.

Thermal and Sound Insulation Treatments

Metal containers have high thermal conductivity, necessitating multi-layer construction to compensate for thermal performance:

• Three-Layer Construction: The outer layer is galvanized steel for wind and sand resistance, the middle layer is 80-100 mm of rock wool for thermal insulation, and the inner layer is PVC-clad steel plates to reduce radiation.
• Local Optimization: An elevated layer can be added at the bottom of the container to block ground cold bridges, and double-glazed or triple-glazed windows can be used for doors and windows to reduce heat loss.
• Sound Insulation Measures: Rock wool sandwich panels inherently possess sound insulation properties. If used for office or residential purposes, sound insulation cotton or rubber pads can be added at the joints.
