Integrated Modular Prefabricated Housing
Integrated modular prefabricated housing is mainly divided into two types: modular housing and integrated housing, which differ in terms of prefabrication methods and construction characteristics.
Modular Housing: It adopts a fully prefabricated production model, using individual rooms as module units. In the factory, over 90% of the processes are completed, covering key components such as the steel structure system, exterior facade, and pre-embedded water and electricity interfaces. It involves the fabrication and installation of the building's main structure, enclosure, equipment pipelines, and interior decoration in the factory, ultimately forming standardized prefabricated assembled spatial modules. After these modules are manufactured, they are transported to the construction site and assembled into a complete building through connection methods. Its core characteristics are distinct: design standardization ensures that each module has uniform specifications and dimensions, facilitating large-scale production and construction; factory production guarantees that the production process takes place in a controlled factory environment, improving product quality and production efficiency; and construction assembly reduces the workload and time required for on-site construction, lowering construction difficulty and environmental impact.
Integrated Housing: It employs a subsystem prefabrication approach, consisting of systems such as the structure, floor, and roof. Unlike modular housing, integrated housing requires the connection of various systems during on-site assembly. This means that on the construction site, workers need to perform more operations to complete the assembly of the house, resulting in a higher proportion of on-site construction compared to modular housing. Due to subsystem prefabrication, integrated housing requires greater attention to the compatibility and coordination between systems during the design and production processes to ensure smooth connection during on-site assembly and the formation of a stable, complete building structure.
In practical applications, modular housing is more suitable for large-scale projects with high requirements for construction speed and quality, as well as complex site conditions; while integrated housing has certain advantages in smaller-scale projects with higher flexibility requirements.
