Production Process of Prefabricated House Components

The production process of prefabricated house components mainly includes factory module disassembly, component fabrication, information management, and on-site assembly, with the specific process as follows:

1. Module Disassembly and Parallel Operations In the factory, the entire building is disassembled into independent modules, which can be produced in parallel to improve efficiency. For example, components such as walls and floor slabs can enter different production lines simultaneously, enabling large-scale manufacturing through standardized design.

2. Component Fabrication Process

• Edge Formwork and Rebar Installation: First, edge formwork is installed to fix the shape of the component, followed by the laying of rebar mesh to ensure structural strength. Some operations use automated equipment such as welding manipulators for high-precision operations.
• Concrete Pouring and Vibration: The concrete is uniformly fed into the mold by a布料斗 (concrete hopper), and the vibration table removes air bubbles through high-frequency vibration to ensure concrete density.
• Insulation and Connector Installation: Insulation boards are installed on the surface of the component to enhance energy efficiency, while connectors (such as embedded bolts and sleeves) are embedded to provide fixing points for subsequent assembly.
• Surface Treatment: After initial manual troweling, a troweling machine performs secondary fine treatment to ensure surface flatness meets design requirements (with errors controlled in millimeters).

3. Curing and Stacking Management

• Pre-curing and Curing: After initial curing in a pre-curing chamber, the components are stacked by a stacking machine and sent to a curing chamber, where a constant temperature and humidity environment accelerates strength development. The curing cycle is adjusted according to the concrete mix.
• Turning and Transportation: After curing, a turning machine adjusts the orientation of the components for loading, and they are finally transported to the construction site.

4. Informatization and Precision Control Each prefabricated component is equipped with an 'ID card' that records information such as project name, model, and production date, enabling full lifecycle traceability. During the design phase, millimeter-level error control is adopted, combined with automated vertical warehouses and intelligent production lines (such as assembly stations for loose parts), to ensure component interchangeability and assembly precision.

5. On-site Assembly Application After being transported to the construction site, the prefabricated components are lifted into place by lifting equipment according to the design drawings and quickly fixed using embedded connectors to form a complete building structure. This method shortens the construction period, reduces on-site wet operations, and improves construction quality.
