Construction of Container Houses
The construction of container houses mainly adopts a modular building approach, where the house is disassembled into standardized modules, prefabricated in factories, and then transported to the site for assembly. The construction process and characteristics are as follows:
Factory-Prefabricated Modules
The core of container house construction lies in modularization and prefabrication. The house is divided into independent modules such as the bottom, top, and four sides, and the main structure, plumbing, internal decoration, and even soft furnishings are integrated and manufactured on the factory assembly line. For example, the steel structure modular production line of a smart factory in Guangdong, through the collaborative operation of welding, assembly, and grinding robots, can produce 50 modules per day with a manufacturing accuracy stable at 1-2 millimeters. The modules use a steel frame paired with flame-retardant rock wool sandwich panels, integrating insulation, fire resistance, sound insulation, and waterproofing. Some enterprises also solve the cold and hot bridge effect of the metal container walls through a broken-bridge lining structure, reducing indoor temperature fluctuations by about 40% compared to traditional color steel plate houses.
Transportation and On-Site Assembly
After the prefabricated modules are shipped to their destination by container, on-site assembly only requires lifting and joint treatment. Taking an Australian project as an example, after the modules arrive, they are combined with a steel structure roof frame to form the initial shape, and then water and electricity are connected on-site for immediate occupancy. The installation period is shortened by more than half compared to traditional methods. The 63 modular elderly care apartments purchased by British merchants took only two weeks from shipment to completion of lifting; the overall delivery period of a hotel project in Papua New Guinea was compressed from 14-18 months to 7 months.
Technical Advantages
- Quality and Efficiency: Standardized factory production avoids on-site wet operations, reduces human errors, and steel waste is only 3%-5%, which is more than half lower than that on traditional construction sites.
- Environmental Protection and Recycling: Modules can be repeatedly disassembled and relocated to different sites, reducing construction waste by 60%-70% and achieving a material recovery rate of over 95%. For example, transforming a standard container can reduce carbon emissions from steel production by about 3.5 tons.
- Strong Adaptability: By adjusting the combination of modules, it can meet diverse needs such as residences, shops, and art galleries. The curved design of container homestays can also optimize wind resistance and drainage performance.
