How to Make a Prefabricated House Space Capsule

The production of prefabricated house space capsules primarily employs modular construction and factory prefabrication methods, with key steps outlined as follows:

1. Design Planning

Determine the capsule's dimensions, internal layout, and performance indicators based on usage scenarios (such as scenic spots, temporary residences, emergency shelters) and functional requirements (such as occupancy numbers and facility configurations). Focus on considering transportation size limitations (such as road height restrictions and container specifications) and lifting attachment point design to ensure safe transportation and installation of modules. For example, individual modules typically do not exceed 12 meters in length and 3 meters in width to accommodate conventional transportation vehicles.

2. Structural Fabrication

• Skeleton Construction: Build the main frame using steel or aluminum alloy profiles, shaped through cutting, bending, and spot welding processes. Steel structures require hot-dip galvanizing or anti-rust paint coating, while aluminum alloys are enhanced for corrosion resistance through anodizing.
• Frame Reinforcement: Use hot-dip galvanized steel plates or aluminum alloy frames for full-weld reinforcement to ensure structural strength. For instance, reinforcing ribs are added to the capsule's corners to withstand stresses during transportation and lifting.

3. Wall Composite and Insulation Treatment

• Multi-Layer Composite Walls: Sequentially fill rock wool or polyurethane insulation layers, fire-resistant panels (such as calcium silicate boards), and external cladding structures (such as metal panels or composite decorative panels) to form a closed system that provides thermal insulation, fire resistance, and moisture protection.
• Thermal Break Technology: At indoor-outdoor metal connections (such as window and door frames), use low-thermal-conductivity materials (such as nylon thermal break strips) to interrupt heat conduction paths, reduce thermal bridging effects, and enhance energy efficiency.

4. Internal Facility Installation and System Commissioning

• Modular Integration: Install bathroom, kitchen, intelligent control systems, fresh air, and water supply and drainage modules, with all equipment featuring inspection ports. For example, bathrooms adopt an integrated design that combines toilets, showers, and sinks.
• Electrical Safety: Run high-voltage circuits through flame-retardant conduits separately, while weak electrical signal lines use shielded twisted pairs and include reserved sensor interfaces (such as temperature and humidity sensors) to ensure system compatibility.

5. Pre-Delivery Inspection

• Water Spray Test: Simulate heavy rain conditions to test the waterproof performance of walls and window/door seams.
• Structural Verification: Use laser measuring instruments to check for dimensional deviations in the capsule body, ensuring precise module-to-module alignment.
• Air Quality Testing: Measure concentrations of harmful substances such as formaldehyde and benzene, ensuring compliance with national standards before delivery.

6. Transportation and On-Site Installation

• Transportation Method: Transport via flatbed trucks or containers, using fixed brackets between modules to prevent shifting.
• On-Site Assembly: Use cranes to place modules onto prefabricated foundations (such as concrete piers or steel structure supports), connecting them via bolts or welding, and finally connecting utilities for use.

Precautions: Material selection should balance weight, strength, and insulation performance (e.g., aluminum alloys are lightweight but costly, while steel is sturdy but prone to rust); module division should consider both transportation limitations and lifting conditions; seams should be treated with sealants or rubber strips to prevent leakage.
