New Type Container House Production

The production of new-type container houses combines modular architectural concepts with industrialized production methods, achieving efficient construction through standardized design, factory prefabrication, and rapid on-site assembly. The core processes and key technologies are as follows:

1. Design and Standardized Disassembly

Container houses use standard containers (such as 20-foot and 40-foot units) as basic modules, with adaptive combination designs based on functional requirements. For example, a single container can be transformed into an independent bedroom or office, while multiple containers can be stacked or joined to form multi-story buildings or large-span spaces. During the design phase, emphasis is placed on structural mechanical stability, with three-dimensional modeling and stress analysis used to optimize container connection nodes, ensuring wind and earthquake resistance meet building codes (e.g., GB50011-2010). Some companies adopt all-steel structural frames and hot-dip galvanized anti-corrosion treatment to enhance container durability, making them suitable for environments with large temperature variations and strong winds.

2. Factory Prefabrication and Integrated Production

1. Structural Processing: Automated production lines are used for steel cutting, welding, and surface treatment. For example, C-shaped steel purlins are added to the bottom beams to enhance floor rigidity, with frame welding precision controlled within 1-2 millimeters and weld strength meeting GB/T 19001-2016 standards.
2. Functional Integration: Walls, roofs, plumbing, electrical systems, bathroom fixtures, and cabinets are pre-installed in the factory. For instance, rock wool sandwich panels are used for wall insulation, PVC-clad steel plates reduce heat radiation, and integrated bathroom technology ensures waterproofing.
3. Quality Inspection: Trial assembly verifies component compatibility, while QR code scanning retrieves production records to ensure traceability for each module. Some companies achieve a daily production capacity of 50 modules, reducing construction time by over 60% compared to traditional buildings.

3. On-Site Assembly and Construction Key Points

1. Foundation Preparation: Clear ground debris and compact the surface. For long-term use, pour a concrete strip foundation (30-50 cm wide) with a horizontal error controlled within 2 millimeters per meter to prevent uneven container settling.
2. Lifting and Positioning: Use steel cables to lift all connection points simultaneously. After the container is in place, pad any local voids to ensure full contact between the bottom beam and the foundation.
3. Connection and Reinforcement: Containers are fixed using bolts or welding, with waterproof sealing applied at joints. For multi-story stacking, additional horizontal connection beams are added to enhance overall stability.

4. Performance Optimization and Scenario Adaptation

1. Thermal Compensation: To address the high thermal conductivity of metal containers, a three-layer structure (outer galvanized steel plate + intermediate rock wool insulation layer + inner PVC plate) is used, along with an elevated floor to block ground cold bridges, reducing indoor temperature fluctuations by 40%.
2. Functional Zoning: Space efficiency is achieved through convertible furniture, such as wall-mounted folding tables and drop-down beds, catering to scenarios like temporary accommodations and cultural tourism homestays.
3. Environmental Protection and Reusability: Modular design supports multiple disassembly and reassembly of containers, though regular inspection of bolt fatigue is required. The risk of structural deformation increases by approximately 15% after more than five disassembly cycles.
