Prefabricated House Prefabrication Process
The prefabrication process of prefabricated houses involves breaking down the building into independent modules, completing manufacturing in a factory, and assembling them into shape through highly automated equipment to achieve standardized and precise production of building components.
Firstly, building module disassembly and design is the foundation of the prefabrication process. Prefabricated buildings decompose the overall structure into independent modules such as ceilings, walls, and bathroom waterproof layers. Each module requires separate design and production planning. During the design phase, precision must be strictly controlled. For example, China Construction Hailong Intelligent Construction Industrial Park requires that the positioning error of each steel bar be measured in millimeters to ensure tight splicing between modules. At the same time, each module is assigned a unique 'ID card' that records information such as the project name, product model, and production date, enabling full lifecycle traceability management.
Secondly, factory-based phased production is the core link. Scattered components are manufactured simultaneously at different workstations according to floor or functional zones: wall modules are completed on dedicated production lines with steel bar binding, concrete pouring, and curing; bathroom modules integrate waterproof layers, pipeline embedding, and other processes; ceiling modules are formed through automated formwork systems. This parallel production model significantly shortens the construction period. For example, China Construction Hailong Industrial Park has an annual production capacity of 20,000 to 30,000 modules, with efficiency far exceeding traditional cast-in-place construction.
Finally, high-precision assembly and quality control determine building quality. After production, each module is transported to the assembly platform for automated splicing using welding manipulators, CNC positioning systems, and other equipment. The assembly process simulates the on-site construction environment to ensure that the connection strength between modules meets design requirements. Additionally, millimeter-level error control standards are adopted throughout the process, complemented by 3D scanning technology for real-time detection of component dimensions to avoid manual operation errors. For example, the对接 (butt joint) of steel bars between modules requires calibration using laser positioning systems, while the thickness of concrete pouring is automatically monitored by sensors to ensure structural safety and durability.
This technology combines factory-based production with on-site assembly, achieving industrial transformation in construction. It offers advantages such as short construction periods, strong quality controllability, and significant environmental benefits, making it an important development direction in the modern construction field.
