How to Make Prefabricated Space Houses

The production of prefabricated space houses adopts prefabricated building technology, which is completed through modular design, factory prefabrication, and on-site assembly. The specific process is as follows:

1. Project Evaluation and Scheme Design It is necessary to comprehensively consider the usage scenarios (such as space bases, extreme climate zones, etc.), local climatic conditions (temperature, radiation, wind pressure, etc.), and customer needs to determine the functional zoning and structural form of the house. During the design phase, it is essential to focus on transportation constraints (such as container dimensions) and the distribution of lifting force points to ensure that the modules do not deform during transportation and installation. For example, the space capsule frame needs to reserve lifting holes and use finite element analysis to verify structural strength.

2. Raw Material Processing and Component Manufacturing

   • Main Framework: High-strength steel (such as hot-dip galvanized steel, aluminum alloy) or composite materials are used to form the frame through laser cutting, CNC bending, welding, and other processes. For example, hot-dip galvanized steel or aluminum alloy is commonly used for space capsule frames, with stainless steel connectors at the joints to enhance fatigue resistance.
   • Facade and Enclosure System: The outer layer is made of lightweight metal panels (such as aluminum-magnesium-manganese panels) or composite material panels, filled with insulation materials like aerogel and rock wool inside, and embedded with soundproof felt. Panel processing requires high-precision cutting using laser cutting or CNC plasma cutting machines, and irregular components such as roof beams are processed into the designed curvature using bending machines.
   • Functional Components: Windows and doors use double-glazed glass with sealing strips, bathroom facilities have pre-embedded waterproof interfaces, and smart devices (such as temperature control systems and sensors) have reserved wire slots.

3. Modular Assembly Integrated installation of interior and exterior walls, floors, ceilings, windows and doors, concealed pipelines (water, electricity, network), bathroom facilities, and smart devices is completed in the factory. For example, a prefabricated tea room space capsule integrates the tea-tasting area, storage area, and rest area into one module, maintaining stable humidity inside through smart temperature control and ventilation systems, using weather-resistant steel and insulation materials on the outside, adopting standardized design for module interfaces, and pre-embedding pipelines to reduce on-site construction volume.

4. Pre-delivery Inspection

   • Water Spray Test: Simulate a heavy rain environment to test the waterproof performance of exterior walls and windows and doors.
   • Structural Dimension Verification: Use a 3D laser scanner to verify whether the module dimension deviations are within the allowable range (usually ≤ ±2mm).
   • Electrical Safety Inspection: Test the grounding resistance, insulation performance, and circuit load capacity.
   • Indoor Air Quality Inspection: Ensure that the concentrations of harmful substances such as formaldehyde and TVOC meet the standards.

5. Transportation and On-site Installation Transport the modules to the destination by flatbed trucks or containers, use cranes to lift the modules onto pre-prepared foundations (such as reinforced concrete piers or steel structure supports), fix the connectors between modules with bolts or welding, and finally connect the water and electricity and debug the smart system for use.
