Hefei Rural Prefabricated Houses

Prefabricated houses in rural Hefei, represented by assembled steel-structure technological agricultural houses, are characterized by efficient construction, high safety, and diverse functions, while old prefabricated houses require regular physical examinations.

I. Application and Advantages of Assembled Steel-Structure Technological Agricultural Houses Assembled steel-structure technological agricultural houses have found practical applications in Hefei. For example, relevant processes were showcased at the "Wan Haofang" Technology Exhibition in Luogang Park, Hefei. Their core advantage lies in construction efficiency: taking a two-story, 170-square-meter rural self-built house as an example, the main structure can be completed in just 15 days. All components of the house are standardized and produced in factories, and only 3 to 4 workers are needed on-site to assemble the main structure like building blocks. This model significantly shortens the construction cycle and reduces the complexity and labor requirements of on-site operations.

II. Significant Improvements in Safety and Functionality

1. Seismic Performance: The assembled steel frame and flexible support structure elevate the seismic fortification intensity of the house to above 8 degrees, far surpassing traditional buildings, making it particularly suitable for areas with complex geological conditions or frequent earthquakes.
2. Energy Self-Sufficiency: The roof can be equipped with a photovoltaic power generation and energy storage system, enabling self-sufficiency in electricity consumption, reducing reliance on the traditional power grid, and aligning with the trend of green building development.
3. Scalability: Steel structural components can be reused, providing space for house renovation and expansion, and avoiding the waste of resources associated with the demolition and reconstruction of traditional buildings.
4. Smart Monitoring: Smart sensors are implanted inside each assembled steel structural component, allowing homeowners to monitor data such as the structural safety and settlement deformation of the house in real-time, facilitating timely maintenance and effectively addressing the issue of "disconnection between construction and management" in rural houses.

III. Maintenance Requirements for Old Prefabricated Houses The technical guidelines issued by Hefei City in February 2026 stipulate that prefabricated perforated-panel buildings constructed between 1970 and 1990 must undergo a physical examination at least once every two years. Due to their early construction dates, the structural performance of these houses may have degraded, and regular physical examinations can promptly identify potential safety hazards and ensure living safety.

In summary, assembled steel-structure technological agricultural houses are the mainstream in rural Hefei's prefabricated houses, combining advantages such as efficiency, safety, and intelligence. Meanwhile, the maintenance and management of old houses are also supported by policies, forming a comprehensive guarantee system from new construction to maintenance.
