Container House Factory Prefabrication
The factory prefabrication of container houses involves disassembling the building into independent modules, completing the prefabrication of the main structure, interior decoration, and equipment pipelines in the factory, and then quickly assembling them into a building after transportation to the site.
I. Prefabrication Content The factory prefabrication of container houses covers all elements of the building. In terms of the main structure, standard containers are used as the base, and the frame is reinforced through welding, riveting, and other methods to ensure structural stability. Interior decoration includes the treatment of walls, floors, and ceilings, such as using lightweight panels, composite flooring, and other materials to complete the basic decoration. The prefabrication of equipment pipelines is a core part, where water and electricity lines, fire protection systems, ventilation ducts, etc., are precisely laid out in the factory according to design drawings and fixedly connected to the main structure. Bathroom facilities are also prefabricated as a whole, including toilets, sinks, shower equipment, etc., forming independent functional units. For example, CIMC's prefabrication rate for the Hong Kong student apartment project was as high as 98%, with all interior decoration and equipment pipelines completed in the factory, and only the connection of water and electricity interfaces required on-site for use.
II. Technical Advantages The factory prefabrication model has significant advantages. High Quality Controllability: Standardized production processes and precision processing equipment are used in the factory to avoid quality fluctuations caused by environmental and human factors in on-site construction, such as the sealing of pipeline connections and the flatness of walls, which are superior to traditional construction. Improved Construction Efficiency: Modular production enables parallel operations of multiple processes, such as completing interior decoration while prefabricating the main structure, shortening the overall construction period. Taking the CIMC project as an example, on-site assembly only takes a few days, reducing the construction period by more than 50% compared to traditional buildings. Optimized Environmental Performance: Construction waste is centrally processed in the factory, reducing on-site dust and noise pollution, while material optimization (such as using recyclable steel and eco-friendly panels) reduces carbon emissions throughout the life cycle.
III. Assembly Process After the prefabricated modules are transported to the construction site, they are spatially positioned according to the design drawings using lifting equipment, and the modules are connected using high-strength bolts or welding. Key nodes include structural docking (ensuring the verticality and levelness of the frame), pipeline connection (using quick connectors to achieve the connection of water and electricity systems), and sealing treatment (using waterproof strips to fill the gaps between modules). The entire assembly process is similar to 'building blocks', but it must strictly follow construction specifications. For example, the CIMC project uses BIM technology for three-dimensional simulation to identify and resolve pipeline conflicts in advance, ensuring one-time successful on-site assembly.
