Dongyuancun The Processing and Installation of Space Capsule Container Houses

Dongyuancun

Dongyuancun I. Processing Processes and Technical Key Points

1. Design and Material Selection

Dongyuancun

Dongyuancun Modular Design: Use standardized containers (such as 20/40 feet) as basic units, and optimize the space layout with the help of BIM technology to ensure the flexibility of splicing and the stability of the structure.

Dongyuancun

Material Selection: The main body adopts a weathering steel (such as Corten steel) or galvanized steel frame. Lightweight composite materials (such as aluminum honeycomb panels + rock wool insulation layer) are used for the internal and external walls, which have both strength and thermal insulation performance.

Dongyuancun

Compliance: The design needs to comply with international container construction codes (such as ISO 668) and the building safety standards of the target area (such as wind resistance and seismic grade).

Dongyuancun 2. Main Body Processing

Dongyuancun Structural Transformation: Cut the side panels of the container to form door and window openings, and laser cutting ensures precision; install H-shaped steel or square tube skeletons inside to enhance the load-bearing capacity (for example, additional support is required for the second floor structure).

Dongyuancun

Dongyuancun Surface Treatment: After sandblasting to remove rust, coat with an epoxy primer + polyurethane topcoat, or use externally hung anodized aluminum plates to improve corrosion resistance.

Dongyuancun

Dongyuancun Thermal and Sound Insulation: Fill with a polyurethane foam layer (thickness ≥ 80mm), combined with double-layer insulating Low-E glass to achieve high energy efficiency with a U-value ≤ 0.3 W/m²K.

Dongyuancun 3. Pre-installation of Functional Systems

Dongyuancun

Dongyuancun Pre-embedding of Water and Electricity Pipelines: Integrate PPR pipes and flame-retardant cables, pre-install an intelligent control system (such as the KNX bus), and reserve photovoltaic interfaces to support off-grid power supply.

Equipment Integration: Embed a split-type air conditioner and a fresh air system (PM2.5 filtration efficiency ≥ 95%). The kitchen and bathroom adopt overall modular installation (such as one-piece forming of 304 stainless steel).

4. Interior Fine Decoration

Dongyuancun

Dongyuancun Environmentally Friendly Materials: Select formaldehyde-free panels (such as OSB board + water-based paint), and lay SPC snap-lock flooring on the ground (waterproof and moisture-proof).

Dongyuancun

Smart Home: Pre-install embedded IoT devices (such as voice control panels, electric curtain rails), and support 5G/Wi-Fi 6 access.

Dongyuancun II. Installation Processes and Technical Specifications

Dongyuancun 1. Site Preparation

Dongyuancun

Foundation Treatment: Select the foundation form according to the geological report - use pile foundations (such as micro steel pipe piles) in soft soil areas, and for hard foundations, a concrete raft foundation (thickness ≥ 200mm) or a steel structure ground beam can be used.

Dongyuancun

Pre-connection of Water and Electricity: Pre-embed water supply and drainage pipes and cable trenches, and install a septic tank or connect to the municipal pipeline network (it needs to meet local environmental protection requirements).

2. Hoisting and Fixing

Module Transportation: Use a low-bed flatbed truck for transportation, and control the weight of a single container within 25 tons (standard for a 40-foot HQ container).

Dongyuancun

Dongyuancun Precise Positioning: Use a total station to calibrate the level. Connect the modules with high-strength bolts (such as grade 10.9) or welding, with an error ≤ 3mm.

Dongyuancun

Wind-resistant Anchoring: The diameter of the anchor bolts ≥ M20, and the depth ≥ 500mm. In typhoon areas, additional diagonal steel cables (such as Φ12mm steel wire ropes) need to be added.

3. System Joint Debugging

Dongyuancun Pipeline Connection: Connect the water and electricity pipelines with quick connectors, and conduct a pressure test (maintain a pressure of 0.6MPa for the water supply for 30 minutes without leakage).

Dongyuancun

Energy System: Optimize the inclination angle of the photovoltaic panels according to the local latitude, and configure the capacity of the energy storage battery pack (such as LiFePO4) at 1.5 times the daily power consumption.

Dongyuancun

Dongyuancun 4. Acceptance and Debugging

Dongyuancun

Dongyuancun Structural Safety: A third-party testing agency issues a load report (such as the live load on the top ≥ 150kg/m²).

Environmental Protection Certificate: Ensure that the formaldehyde emission of the materials ≤ 0.03mg/m³ (EN 717-1 standard), and the noise level ≤ 40dB (A).

Dongyuancun III. Innovation and Cost Optimization Suggestions

Dongyuancun

Dongyuancun Rapid Disassembly and Assembly Technology: Develop patented connection nodes (such as mortise and tenon-style buckles) to shorten the on-site installation time to within 3 days.

Dongyuancun

Dongyuancun Circular Economy: Transform second-hand containers (cost reduced by 30%), and match them with a detachable interior installation system for easy secondary use.

Dongyuancun

Dongyuancun BIPV Technology: Integrate thin-film solar panels (such as CIGS) as exterior wall materials to achieve a zero-energy consumption building.

IV. Regulations and Market Adaptation

Dongyuancun

Dongyuancun Approval Process: In some regions, container buildings are classified as temporary facilities (no building planning permit is required), but they need to meet fire protection (such as GB50016) and electrical safety codes.

Dongyuancun

Application Scenarios: Focus on promoting it in fields such as cultural and tourism homestays (such as in mountainous areas and coastal areas), emergency housing (delivered within 72 hours), and mobile commercial spaces (coffee shops, exhibition halls), etc.

Dongyuancun

Through standardized production and intelligent management, the space capsule container house can significantly reduce the comprehensive cost (about ¥2000-4000 yuan/m²), and become an important solution for sustainable buildings. In actual projects, customized design is required in combination with the local climate (such as adding underfloor heating in extremely cold regions) and cultural aesthetics.
