Prefabricated House Installation Methods
The installation methods for prefabricated houses mainly include modular assembly, vertical stacking of box components, interlaced stacking of box components, and assembly of box components with prefabricated panels. Here are the specific details:
Modular assembly is one of the core methods for installing prefabricated houses. Its core logic involves breaking down the entire building into multiple independent modules, each of which is standardized and produced in a factory, including the ceiling, floor, walls, and pre-embedded internal water and electricity pipelines. After the modules are transported to the construction site, they are precisely lifted using lifting equipment and assembled according to the design drawings to form a complete building. The advantages of this method include high construction efficiency, strong quality controllability, and the reusability of modules, making it suitable for standardized building scenarios such as residential buildings, schools, and hospitals. For example, some temporary medical facilities use modular assembly, enabling construction and commissioning within a few days.
Vertical stacking of box components is suitable for low- to mid-rise buildings (below 12 floors). Its principle involves vertically stacking prefabricated box components to form structural stability through the self-weight and friction of the components. In non-seismic areas, no additional connection measures are required between box components for buildings below 5 floors; however, in seismic areas or for taller buildings, methods such as post-tensioning technology, cast-in-place continuous balconies or corridors, and bolt connections are needed to enhance overall structural integrity. For example, some residential buildings in earthquake-prone areas adopt this method by reserving chain slots in the wall ribs of box components and pouring concrete after installation to form cast-in-place structural columns, significantly improving seismic performance.
Interlaced stacking of box components achieves material savings by optimizing component arrangement. Its characteristic involves interlacing box components horizontally or vertically to avoid repetition of adjacent sides, thereby reducing structural redundancy. This combination method reduces material usage by approximately 10%-15% while ensuring structural strength, making it suitable for economical residential buildings or temporary structures. For example, some post-disaster reconstruction projects adopt this method to effectively control construction costs while meeting basic housing needs.
Assembly of box components with prefabricated panels combines the advantages of modularization and panelization. Its core involves designing rooms with dense equipment pipelines or heavy decoration workloads (such as bathrooms and kitchens) as box components, while the remaining parts are assembled using prefabricated panels (such as wall panels and floor panels). This method reduces on-site wet work by approximately 60%, significantly shortening the construction period while facilitating later maintenance and renovation. For example, some high-end residential projects adopt this method by using prefabricated bathroom boxes for “overall lifting”, avoiding leakage issues common in traditional decoration.
