Yichun Container House Design
The design of container houses in Yichun City needs to integrate regional environmental and green concepts, with specific design points as follows:
1. Structural Treatment and Modular Combination
Container houses should be cut, spliced, and combined according to functional requirements to form open indoor spaces. Cutting areas (such as door and window openings) should be reinforced with additional steel beams, angle irons, or welding to ensure structural stability. Double-layer containers should have the upper and lower corner fittings precisely aligned using high-strength bolts or welding, and additional diagonal braces and crossbeams should be added to prevent deformation due to concentrated loads. Modular design should reserve pipeline channels for easy integration of water and electricity systems later.
2. Thermal Insulation System
In response to Yichun's harsh winter climate, efficient thermal insulation materials should be applied inside and outside the container. Exterior walls can use rock wool boards (thickness ≥ 100mm) or polyurethane foam layers, covered with waterproof and breathable membranes; roofs should have double-layer insulation and be sloped to prevent snow accumulation; floors should be laid with extruded polystyrene boards (XPS) and covered with a moisture-proof layer. The insulation layer should be continuous without breaks to avoid cold bridges, and thermal performance testing should be conducted after construction.
3. Rust Prevention, Corrosion Resistance, and Weather Resistance
The steel container body should be thoroughly derusted (sandblasted to Sa2.5 grade) and then painted with epoxy zinc-rich primer (dry film thickness ≥ 80μm) and polyurethane topcoat (dry film thickness ≥ 60μm). In the humid forest environment, a moisture-proof layer (such as an asphalt coating) should be added at the bottom of the container, and the foundation should be raised to avoid direct contact with the ground. Seams around door and window frames should be sealed to prevent rainwater infiltration and rusting.
4. Interior Space and Functional Integration
Interior decoration should meet living needs: walls can be covered with gypsum boards or wood veneer panels; floors can use composite flooring or tiles; water and electricity systems should have pipelines embedded and maintenance access points reserved; heating should preferably use underfloor heating (to be laid on the insulation layer) or air-source heat pumps; fresh air systems should have filtration devices to address forest pollen issues. Double-story houses should have independent staircases designed with steel or concrete steps, and shock-absorbing pads should be added at the connections with the container body.
5. Regional Adaptability Design
The architectural appearance should downplay the industrial feel: exterior facades can incorporate natural materials such as wood and glass, with local cutouts or staggered designs echoing the forest landscape; colors should be subdued tones like gray and brown to blend with the surrounding environment. Modular construction can reduce on-site wet work, lower construction noise and dust, and meet ecological protection requirements.
6. Green Attributes of Material Lifecycle
Retired containers used as the main structure can reduce carbon emissions from steel smelting. Before modification, the original strength of the container body should be evaluated (such as through CSC certification) to avoid excessive cutting that could damage structural integrity. Demolished old materials (such as corner fittings and corrugated panels) can be recycled for decorative components, achieving a closed-loop resource utilization.
