Large-Scale Cement House Prefabricated Modules

Large-scale cement house prefabricated modules are core components for constructing houses using a factory-prefabricated + on-site assembly model, belonging to the prefabricated reinforced concrete full-frame shear wall structural system.

1. Production Process and Structural Features
Prefabricated modules are cast in one piece using high-precision molds at specialized production bases, covering core components such as walls, floor slabs, and beams and columns. Each module integrates multiple structures: an internal steel reinforcement framework (using Φ8-Φ12 steel mesh) provides structural support; the outer layer is wrapped with an insulation layer (e.g., EPS material slot design, improving thermal insulation performance by 40% after on-site embedding), a waterproof layer, and pre-embedded pipelines, forming standardized “building block” units. For example, a single 30㎡ module takes only 7 days to prefabricate in the factory. After being transported to the site, three workers with a crane can complete the installation of a single module in 4 hours, and the overall construction of a 100㎡ house takes only 2 days, significantly shortening the construction period.

2. Technical Parameters and Performance Advantages
The modules use C30-C40 grade concrete, with a compressive strength of 25-30MPa, which is 1.5 times that of traditional brick-and-mortar structures, meeting high-strength load-bearing requirements. In terms of connection methods, the modules form an integral framework through prestressed bolts and welded steel plates, achieving a wind resistance rating of Level 10 and a seismic fortification intensity of 7 degrees (equivalent to the destructive force of the Wenchuan earthquake), demonstrating excellent structural stability. Additionally, the modular design supports flexible combination, allowing adjustments to the house layout according to needs and adapting to diverse architectural scenarios.

3. Typical Application Scenarios
In addition to civil buildings, large prefabricated modules are widely used in the industrial sector. For example, the Zhangzhou Nuclear Power Unit 4 in 2026 adopted a prefabricated concrete module construction technique, with the first hoisted module weighing 454.289 tons, validating its feasibility in super-heavy industrial buildings. These modules, through factory-standardized production and rapid on-site assembly, effectively address issues such as long construction periods and quality fluctuations associated with traditional cast-in-place methods, becoming an important direction for the development of modern building industrialization.

4. Environmental Protection and Economic Efficiency
The factory-prefabricated model reduces on-site wet operations, lowering dust and noise pollution, while optimizing material utilization through centralized production and reducing construction waste. Although the initial mold investment cost is relatively high, after large-scale production, the overall cost can be lower than traditional construction methods, making it particularly suitable for mass-construction projects such as affordable housing and emergency shelters.
