Rural Integrated Prefabricated Housing Structure

The rural integrated prefabricated housing structure, centered around prefabricated rural houses, achieves efficient construction through factory-prefabricated components and on-site assembly, offering advantages such as short construction periods, strong earthquake resistance, and energy efficiency.

1. Structural Types and Construction Characteristics

Prefabricated rural houses mainly fall into two types: light steel structures and concrete shear wall structures. Taking Zhejiang Province as an example, core components such as walls and floors are standardized and prefabricated in factories, enabling rapid assembly through mechanical connections. For instance, the main structure of the first “fully prefabricated” rural house model in Yuyao City was erected in just about 7 days, significantly shortening the traditional construction period. Factory production also ensures component precision, reduces on-site wet work, and minimizes construction errors and material waste.

2. Performance Advantages

1. Earthquake Resistance: Mechanical connections (e.g., bolts, welding) are used at joints, allowing for an earthquake resistance intensity of up to 7 degrees, suitable for earthquake-prone regions.
2. Thermal and Sound Insulation: Walls are constructed with 25 cm-thick reinforced concrete sandwiched with lightweight insulation panels, combined with EPDM leak-proof seals and double-layer coating waterproofing technology to achieve multiple functions including thermal insulation, sound insulation, and moisture resistance.
3. Energy Efficiency and Environmental Protection: Factory prefabrication reduces on-site dust and construction waste, with high material recyclability, meeting green building standards.

3. Technical Details and Waterproofing Solutions

The waterproofing technology directly follows the mature solution used in Ningbo Metro shield tunnel segments, forming dual protection through seals installed between wall panels and double-layer coating application, effectively addressing leakage issues in rural houses. Additionally, both light steel and concrete shear wall structures are optimized for mechanical performance through standardized design, ensuring structural safety and durability.

4. Policy Support and Promotion Models

Governments in various regions are promoting the development of prefabricated rural houses through technical guidelines, atlas compilation, and financial incentives. For example, Hebei Province launched a pilot program in 2022, providing a subsidy of 10,000 yuan per household for newly built prefabricated rural houses, and enabling the entire process of application, verification, and claim through the “Yunongtong” APP, reducing construction costs and administrative barriers for farmers. Zhejiang Province, through demonstration projects (such as the Yuyao model house), guides technology popularization, forming a replicable promotion model.

In conclusion, the rural integrated prefabricated housing structure, through modular design, industrial production, and policy support, has become an important direction for the modernization of rural housing construction, offering both economic and social benefits.
