Prefabricated Concrete Houses on Construction Sites
Prefabricated concrete houses on construction sites are modular or prefabricated building forms where building components are industrially produced and assembled on-site. Details are as follows:
Construction Method: Core components such as ceilings, floors, wall panels, and water and electricity pipelines are prefabricated in factories to form standardized modules. These modules are transported to the construction site by cranes and directly hoisted and assembled, eliminating the complex process of traditional on-site pouring. For example, a public housing project in Shenzhen, Guangdong, used 6,028 concrete modules for assembly, reducing the construction period from the conventional 2.5-3 years to 1 year, significantly improving construction efficiency.
Technical Advantages:
- Reduced Construction Time: Factories employ parallel operations and automated production lines, compressing the construction cycle by more than 60%. Modular production allows foundation construction and component manufacturing to proceed simultaneously, greatly reducing on-site work time.
- Quality Control: Component production achieves millimeter-level precision, with each module carrying a unique 'ID card' recording production information. Hidden engineering inspection robots can intercept millimeter-level errors, ensuring stable building quality.
- Environmental Protection and Energy Efficiency: On-site construction noise and dust are reduced by 70%, and construction waste is significantly decreased, meeting green building standards. Factory production also optimizes material utilization, reducing resource waste.
Application Scenarios: Prefabricated concrete houses have been widely used in the construction of residential buildings, apartments, hospitals, hotels, and other fields. For example, the Nanjing Jindi Yufang project adopted a prestressed prefabricated concrete assembled integral frame structure system, and the export value of movable houses in the Guangzhou Customs area reached 1.4 billion yuan in the first four months of 2026, a year-on-year increase of 38.1%, indicating its market expansion potential.
Industrial Support: This technology relies on a complete technical system, intelligent production lines (such as the world's first concrete MiC flexible intelligent manufacturing production line), and industrial cluster support. Currently, China has formed a production capacity of delivering 20,000-30,000 modules annually, providing a solid foundation for large-scale applications.
