Modular Container House Production

Modular container house production involves disassembling a complete house into standardized modules, completing the construction process in a factory, and then transporting them to the site for assembly into a complete building. The specific production process and key points are as follows:

I. Module Disassembly and Design

The entire building is disassembled into independent modules such as the bottom, top, and four sides. Each module includes the main structure, plumbing and electrical systems, interior decoration, and equipment. During the design phase, considerations must be given to the standardized dimensions of the modules, the load transfer paths, and the assembly methods to ensure feasibility for transportation and assembly. For example, steel structure modules use a steel frame paired with flame-retardant rock wool sandwich panels as the main structure, integrating insulation, fire resistance, sound insulation, and waterproofing.

II. Factory Prefabrication

1. Main Structure Manufacturing: Fully automated production lines or robotic collaboration are used to complete welding, assembly, and polishing processes. For example, a domestic intelligent production line can produce 50 steel structure modules per day, with manufacturing precision maintained at 1-2 millimeters.
2. Internal Integration: Interior decoration work such as bathroom waterproofing, bathroom fixtures, cabinets, and wardrobes is completed in the factory, and even soft furnishings are integrated to reduce on-site work.
3. Quality Control: The entire production process is recorded using unique QR code identity tags to ensure traceability of each module. For example, a certain industrial park delivers 20,000 to 30,000 concrete prefabricated modules annually, with over 70% of the processes completed in the factory.

III. Transportation and On-Site Assembly

1. Transportation Method: Modules are transported to their destination by sea or land, similar to containers. During transportation, attention must be paid to securing and protecting the modules to prevent damage.
2. On-Site Assembly: A parallel operation mode is adopted, with multiple processes carried out simultaneously. For example, 87 modular houses transported from Shenzhen to Australia were installed on-site in just a few days, reducing the construction period by more than half compared to traditional methods.

IV. Technical Advantages and Application Prospects

Modular construction significantly shortens the construction period, reduces labor and material waste, and decreases construction waste, dust, and noise pollution through factory-standardized production. Its disassemblable and relocatable nature supports cross-border compliance and low-carbon recycling, aligning with global trends in the construction industry's transformation. Currently, modular construction is widely used in engineering camps, cultural and tourism homestays, emergency support, and overseas cross-border projects.
