Prefabricated Reinforced Concrete House
Prefabricated reinforced concrete houses are prefabricated buildings that use prefabricated reinforced concrete modules as their core, adopting factory-based production and modular assembly. Their full name is 'prefabricated reinforced concrete full-frame shear wall structure houses'.
Key advantages are as follows:
High efficiency: The separation of factory prefabrication and on-site assembly significantly shortens the construction period. A single 30㎡ module can be prefabricated in the factory in just 7 days. 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. Some cases show that a villa can be assembled in just 4 hours, greatly improving construction efficiency.
Low cost: Taking a 120㎡ self-built rural house as an example, the cost of a traditional brick-and-mortar structure is approximately 180,000 to 220,000 yuan, while the cost of the main modules of a prefabricated concrete house is only 120,000 to 150,000 yuan, reducing the overall cost by 30%. The market price range is 220 to 1,100 yuan per square meter, with some products priced as low as over 300 yuan per square meter. A 200-square-meter main structure can even cost as little as 110,000 yuan, demonstrating significant economic efficiency.
Good environmental performance: Factory-based production enables full process control, with a scrap recovery rate of 95%. There is no dust or sewage discharge at the construction site, and construction waste is only 10% of that of traditional construction, meeting green building standards.
Superior performance: Using C30-C40 grade concrete with built-in Φ8-Φ12 steel reinforcement mesh, the compressive strength reaches 25-30MPa, which is 1.5 times that of traditional brick-and-mortar structures. The walls have reserved slots for EPS insulation layers, improving thermal insulation performance by 40%. The wind resistance rating reaches Level 10, and the earthquake resistance design intensity is Level 7, ensuring high structural safety.
High flexibility: The standard module size is 6m×3m×3m (length, width, and height). Horizontal splicing and vertical stacking (up to 3 floors) allow for free combination of house types, suitable for various scenarios such as rural self-built houses, commercial spaces, and cultural tourism projects. In addition, the warranty period can reach 70 years, highlighting long-term use value.
This technology combines modular design, industrial production, and standardized construction, balancing efficiency, cost, and performance, and providing an efficient and environmentally friendly solution for the construction industry.
