Construction of Container Houses
The construction of container houses mainly includes three core processes: factory prefabrication, transportation, and on-site assembly, characterized by high integration, standardization, and rapid deployment capabilities.
1. Factory Prefabrication: Modular Integrated Construction
The core advantage of container houses lies in transforming traditional on-site construction into factory assembly-line production. The house is disassembled into standardized modules such as the floor, roof, and side walls, with full-process prefabrication completed in the factory, including the main structure (e.g., steel frames), plumbing and electrical systems, interior finishes (including bathrooms, cabinets, and wardrobes), and even soft furnishings. For example, a smart factory in Guangdong uses a fully automated production line with welding and assembly robots working in tandem, capable of producing 50 modules per day with precision controlled within 1-2 millimeters, far exceeding traditional on-site construction tolerances. Modular construction adopts a parallel operation model, with multiple processes advancing simultaneously, fundamentally changing the traditional on-site work pattern.
2. Transportation: Standardized Container Form
Prefabricated modules are transported in standardized container form, shipped across oceans or regions via sea or land transport to their destinations. For example, in an Australian project, steel-structured modular houses feature a main structure combining steel frames with fire-resistant rock wool sandwich panels, integrating insulation, fire resistance, sound insulation, and waterproofing. During transportation, they are directly loaded into containers, reducing damage. Improved transportation efficiency benefits from the "port-industry linkage" model, such as the China State Construction Green Industrial Park, located just 20 kilometers from the port, enabling short-distance transfer of modules for immediate loading upon completion, enhancing speed and reducing losses.
3. On-Site Assembly: Rapid Installation and Commissioning
Upon arrival at the site, modules are quickly joined using lifting equipment, requiring only a few processes such as module connection and utility hookups before being put into use. For example, the Australian project site completed installation in just a few days, halving the traditional construction timeline; an 18-story high-rise residential project in Hong Kong adopted modular construction, reducing the construction period from 3-5 years to within 1 year. The assembly phase generates minimal construction waste and noise, meeting green construction requirements. Additionally, modular houses can be repeatedly disassembled and relocated, adapting to multiple scenarios such as temporary housing, cultural and tourism accommodations, and emergency rescue.
4. Quality Control and Safety Standards
The entire construction process must adhere to strict quality and safety regulations. Structural stability must comply with the GB50011-2010 Code for Seismic Design of Buildings, and wind resistance must pass 12-level strong wind simulation tests. For example, the container mobile homes from Suzhou Zhongnan Steel Structure Co., Ltd. exhibited a maximum frame deformation of only 2mm under 12-level strong winds, well below the national standard limit of 10mm. Furthermore, welding quality, the overall building system, and the full modular product process must pass three certifications to ensure compliance.
