Construction Methods for Prefabricated Houses

The construction methods for prefabricated houses mainly include modular construction, prefabricated component assembly, box component assembly, and the construction of prefabricated detachable container houses, with four types in total. Details are as follows:

Modular Construction Method: The entire building is divided into independent functional modules, such as rooms and corridors, with full-process prefabrication of structures, finishes, and utility pipelines completed in the factory. Each module includes ceilings, floors, walls, and integrated water and electrical systems, enabling rapid assembly through standardized interfaces. After being transported to the site, the modules are connected using bolts or welding to form a complete building. This method allows over 90% of the work to be completed in the factory, significantly shortening the on-site construction period and ensuring high quality control, making it suitable for standardized buildings such as residential houses and hotels.

Prefabricated Component Assembly Method: Based on prefabricated concrete or steel structural components, the building's main structure is assembled on-site. For example, foundation piles are fixed using base plates, quick connections between beams are achieved using mortise-and-tenon joints, components such as stairs and floors are installed via lifting, and all gaps are finally grouted. This method can complete the main structure within 14 days, offering high construction efficiency and millimeter-level component precision, reducing on-site wet work, and is suitable for low-rise residential houses or temporary buildings.

Box Component Assembly Method:

• Vertical Stacking of Box Components: Suitable for buildings up to 12 stories high, with houses below 5 stories in non-seismic areas relying on the self-weight and friction of the components for stability; seismic areas or high-rise buildings require reinforcement through post-tensioning, cast-in-place balconies/corridors, bolt connections, or cast-in-place structural columns to enhance overall integrity.
• Staggered Stacking: By staggering the arrangement of box components, side repetition is avoided, optimizing material utilization and reducing costs.
• Combination with Prefabricated Panels: Box components are used in rooms with dense utility pipelines or high decoration requirements, while the remaining parts use prefabricated panels, flexibly balancing functionality and economy.

Construction Method for Prefabricated Detachable Container Houses: Using standardized containers as units, the basic structure is completed through steps such as bottom frame installation, column connection, MGO board laying, and top frame fixation, followed by the installation of wall panels, ceilings, and roof tiles, with reserved wire holes for utility pipeline layout. This method offers detachable and movable characteristics, suitable for scenarios such as temporary offices and post-disaster reconstruction, with a material recycling rate of over 80%.
