How to Package Prefabricated Houses
The packaging process of prefabricated houses mainly includes three core stages: factory prefabrication, encapsulated transportation, and on-site assembly.
The factory prefabrication stage is the foundation of packaging. House modules undergo full-process production within the factory. This process covers all procedures, including wall frame construction, floor and ceiling installation, pre-embedding of water and electricity pipelines, kitchen and bathroom waterproofing, and hard decoration, ensuring that each independent space unit meets the standard of being ready for immediate occupancy. The factory disassembles the entire building into several modular units, such as independent spaces for bedrooms, living rooms, and kitchens, and completes over 80% of the procedures, including the main structure, interior decoration, and installation of electromechanical pipelines, within the workshop. This standardized production model not only improves construction efficiency but also ensures quality stability through industrial process control.
The encapsulated transportation stage addresses the safe transportation of large modules. After production is completed, the modules are encapsulated as a whole and loaded onto vehicles for cross-province and cross-city transportation via large-scale logistics, trailers, or maritime containers. Taking the case of COSCO Shipping Logistics Supply Chain as an example, 184 sets of modular hotel-style apartment containers and steel structural accessories require precise verification of external dimensions, reservation of binding space for the cargo, and formulation of a compact stowage plan to accommodate the ship's cargo hold limitations. Similarly, the "building block houses" manufactured in Jingjiang are transported across oceans in containers in the form of four independent modules, maximizing the utilization of transportation space through modular design. The key to this stage lies in optimizing the loading plan according to the module size, transportation vehicle specifications, and destination conditions, and ensuring structural stability during transportation.
The on-site assembly stage is the final step in the packaging process. After the modules arrive at the designated location, only a few procedures, such as module splicing and water and electricity connection, are required before they can be put into use. For example, overseas projects can be assembled and occupied within a few hours, while domestic customers typically require about two weeks to construct apartments, hotels, or temporary office buildings. The assembly process relies on standardized interface designs between modules, enabling rapid assembly through bolt connections or snap-fit fastenings, while the water and electricity systems achieve plug-and-play functionality through pre-embedded pipelines. This "building block" construction method significantly reduces on-site construction volume and minimizes the impact on the environment and surrounding residents.
