Container Module House Production

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

I. Design and Disassembly

The entire house is divided into several independent modules according to construction requirements, such as the bottom, top, and four side components. Module design must take into account transportation constraints (e.g., container dimensions) and the feasibility of on-site assembly, ensuring that each module can be precisely connected after factory prefabrication. For example, a smart factory in Guangdong disassembled a house into six components, which were simultaneously produced on multiple sub-production lines and finally assembled into a complete container at the end of the production line.

II. Factory Prefabrication

1. Main Structure Manufacturing: The main frame of the module (e.g., steel structure or light steel keel) is welded or bolted together on the factory assembly line to ensure structural stability. For example, a welded container forms a complete structure with strong resistance to deformation; for bolted connections, the tightness of the joints must be checked, and the wall thickness of the columns and bottom beams is usually between 1.5 mm and 3 mm.
2. Internal Integration: Simultaneously complete the embedding of water and electricity pipelines, bathroom waterproofing, installation of bathroom fixtures, cabinets, wardrobes, and other decoration processes. Some projects even integrate interior soft furnishings. For example, the concrete modules in a certain industrial park in Shenzhen are equipped with exclusive QR code identity tags, which can be scanned to retrieve all production records.
3. Surface Treatment: Corrosion-resistant processes such as hot-dip galvanizing are used to treat the surface of the container body to extend its service life. For example, in areas with large temperature differences between day and night and significant humidity changes, hot-dip galvanized coatings are more resistant to rust than cold-dip galvanized coatings.

III. Transportation and Assembly

1. Transportation: The prefabricated modules are transported to their destination by container sea or land freight. For example, 87 modular houses were shipped from Shenzhen to Australia, with a voyage of about 20 days.
2. On-site Assembly: After being transported to the project site, the modules are assembled like building blocks, and a small number of processes such as water and electricity connections are completed before the house can be put into use. For example, at the Australian project site, only the配套 (supporting) steel structure roof truss was needed to erect the overall shape, and the installation was completed in a few days.

IV. Quality and Efficiency Advantages

Modular construction adopts a parallel operation mode, with multiple processes carried out simultaneously, shortening the construction period by more than 60% compared to traditional methods, and significantly reducing construction waste, dust, and noise pollution. For example, a certain industrial park in Shenzhen can deliver 20,000 to 30,000 concrete prefabricated modules annually, with more than 70% of the processes completed in the factory.
