Prefabricated House Construction Process Images
The construction process of prefabricated houses mainly consists of three stages: factory modular production, transportation, and on-site assembly.
Factory Modular Production
The core of prefabricated houses lies in breaking down the building into independent modules and completing standardized production in the factory. Taking the China Construction Hailong Intelligent Construction Industrial Park in Shenzhen, Guangdong, as an example, key components such as ceilings, walls, and waterproof layers in bathrooms are all manufactured in a three-dimensional factory. The factory adopts an assembly-line operation mode, first producing individual components separately, such as door and window frames, water and electricity pipelines, etc., and then transporting these components to the final assembly station for integrated assembly. For instance, wall modules are pre-installed with insulation layers, soundproof layers, and decorative surface layers, while water and electricity pipelines are embedded within the walls, forming complete 'building blocks'. This production method not only improves construction efficiency but also ensures the dimensional accuracy and quality stability of each module through precision equipment.
Transportation Phase
After production, the modules need to be transported from the factory to the construction site. Due to their large size and heavy weight, specialized vehicles and securing devices are required during transportation to prevent deformation or damage to the modules. For example, the prefabricated modules used at a construction site of a real estate project in Shanghai are each labeled with detailed 'ID card' information, including dimensions, materials, installation positions, etc., facilitating transportation and subsequent management. The transportation route needs to be planned in advance to avoid height and weight restriction areas, ensuring the safe arrival of the modules at the site.
On-site Assembly
On-site assembly is the final step in the construction of prefabricated houses, similar to the process of 'building blocks'. Taking a public housing project in Shenzhen, Guangdong, as an example, five residential buildings nearly 100 meters high are assembled from 6,028 concrete modules, with a 70-square-meter two-bedroom unit requiring only two and a half modules for assembly. During assembly, tower cranes lift the prefabricated modules to designated positions, and workers secure the modules together using bolts, welding, or grouting. Each module's interface is designed with connecting structures to ensure overall stability and airtightness. After assembly, finishing work such as exterior wall decoration and equipment debugging is required to complete the building.
The construction process of prefabricated houses significantly shortens the construction period, reduces on-site wet operations and construction waste, and aligns with the development trend of green buildings through factory production, standardized transportation, and modular assembly.
