Prefabricated Reinforced Concrete House

The full name of the prefabricated reinforced concrete house is 'prefabricated reinforced concrete full-frame shear wall structure house'. It is a new type of building form with factory-prefabricated components and on-site assembly as its core processes.

Core Technical Features

1. High Structural Strength: It uses C30-C40 grade concrete with built-in Φ8-Φ12 steel reinforcement mesh, achieving a compressive strength of 25-30MPa, which is 1.5 times that of traditional brick-and-mortar structures. The modules are connected through prestressed bolts and welded steel plates to form an integral frame, with a wind resistance rating of Level 10 and a seismic fortification intensity of 7 degrees (capable of withstanding the destructive force of the Wenchuan earthquake).
2. Excellent Thermal Insulation: The walls are designed with reserved slots for EPS insulation layers, which, when inserted on-site, improve thermal insulation performance by 40%, achieving a warm winter and cool summer effect.
3. Modular Design: Core components (walls, floor slabs, beams, and columns) are cast in one piece using high-precision molds, integrating steel reinforcement skeletons, insulation layers, waterproof layers, and pre-embedded pipelines, allowing for flexible combination like 'building blocks'.

Core Advantages

1. High Efficiency: A single 30㎡ module can be prefabricated in the factory in just 7 days. On-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.
2. Low Cost: Taking a 120㎡ rural self-built house as an example, the cost of a traditional brick-and-mortar structure is approximately 180,000-220,000 yuan (including labor), while the cost of the main modules of a prefabricated house is only 120,000-150,000 yuan, reducing the overall cost by 30%. A case study in rural Henan shows that a full reinforced concrete structure costs only over 300 yuan per square meter, and a villa can be built in four hours.
3. Green and Environmentally Friendly: Factory production achieves a 95% recovery rate of off-cuts, with no dust or sewage emissions on-site, and construction waste is only 10% of that of traditional construction. Environmentally friendly concrete and water-based paints are used, with formaldehyde emissions ≤0.05mg/m³, far below the national standard (0.1mg/m³), enabling 'immediate occupancy upon installation'.
4. Flexible Space: The standard module size is 6m×3m×3m (length, width, height), supporting horizontal splicing and vertical stacking (up to 3 floors), allowing for free combination of house types to meet diverse needs.

Application Scenarios

This technology has been widely applied in rural self-built houses, temporary housing, and post-disaster reconstruction. With its characteristics of rapid construction, economic durability, and environmental protection and energy efficiency, it has become an important direction for modern building industrialization.
