Prefabricated House Construction

Prefabricated house construction primarily adopts modular construction or prefabricated assembly construction methods, offering advantages such as short construction periods, reduced labor requirements, and controllable quality, but it places high demands on industrial infrastructure.

Modular construction divides the entire building into independent modules, with standardized manufacturing of core components such as ceilings, floors, and water and electricity pipelines completed in factories. The modules are then transported to the construction site via sea or land transport and quickly assembled using lifting equipment. For example, in a Chinese-made modular elderly care apartment project purchased by British merchants, 63 modules were shipped from a Chinese factory to a British port and assembled on-site in just two weeks, significantly shortening the cross-border construction period. This method achieves precision control of components through factory production and reduces on-site wet work, thereby minimizing the impact of weather on construction progress.

Prefabricated assembly construction, on the other hand, produces building components through industrial means, including prefabricated products such as beams, slabs, walls, and columns, which are then assembled on-site. Its technical system covers prefabricated concrete structures and steel structures, with main types including panel assembly, box assembly, and frame assembly. The construction process typically involves building the house chassis frame on a pre-poured foundation, laying floor joists, installing prefabricated wall modules, gradually constructing the three-dimensional structure, and finally completing the installation of the roof and other parts. For example, a public housing project in Shenzhen, Guangdong, used 6,028 concrete modules for assembly, reducing the completion and delivery time from the traditional 2.5 to 3 years to just 1 year, demonstrating the efficiency breakthrough of prefabricated construction.

Compared to traditional construction methods, prefabricated house construction can shorten the construction period by more than 60% and reduce on-site labor by approximately 50%. Factory production ensures uniform component quality, avoiding manual operation errors; modular design facilitates later maintenance and updates, extending the building's service life; at the same time, reducing on-site wet work lowers dust and noise pollution, aligning with green building concepts. However, this method places extremely high demands on industrial infrastructure, requiring the establishment of a complete technical system, production system, and industrial cluster, including the coordinated cooperation of standardized design, intelligent production, and professional installation to achieve large-scale application.
