Prefabricated Reinforced Concrete House

Prefabricated reinforced concrete houses are a form of construction that utilizes core components prefabricated in factories and assembled on-site. Their full name is "prefabricated reinforced concrete full-frame shear wall structure houses," and they are characterized by efficiency, cost-effectiveness, environmental friendliness, and flexibility.

Core Process and Structural Features

Prefabricated reinforced concrete houses are manufactured in factories using high-precision molds to create core components such as walls, floors, beams, and columns. Each module integrates a steel reinforcement framework, insulation layers, waterproofing layers, and pre-installed piping systems, forming standardized "building blocks." The structure employs C30-C40 grade concrete with embedded Φ8-Φ12 steel reinforcement mesh, achieving a compressive strength of 25-30MPa, which is 1.5 times that of traditional brick-and-mortar structures. Walls are designed with EPS insulation layer slots for on-site insertion, improving thermal insulation by 40% and ensuring warmth in winter and coolness in summer. Modules are connected using pre-stressed bolts and welded steel plates, forming a unified frame capable of withstanding wind speeds up to Category 10 and seismic intensity of 7 degrees (equivalent to withstanding the destructive force of the Wenchuan earthquake).

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 install a single module in 4 hours, and a 100㎡ house can be fully assembled in just 2 days, reducing construction time by over 50% compared to traditional methods.
2. Low Cost: For a 120㎡ self-built rural house, the cost of a traditional brick-and-mortar structure is approximately 180,000-220,000 yuan, while the cost of the main modules for a prefabricated concrete house is only 120,000-150,000 yuan, reducing overall costs by 30%. If opting for a leasing model, annual rent can be as low as 5,000 yuan per room.
3. Green and Environmentally Friendly: Factory production achieves a 95% recycling rate for offcuts, with no dust or sewage emissions on-site and construction waste amounting to only 10% of that from traditional construction. Environmentally friendly concrete and water-based paints are used, with formaldehyde emissions ≤0.05mg/m³, well below the national standard of 0.1mg/m³, enabling "immediate occupancy" upon completion.
4. Flexible Space: Standard modules measure 6m×3m×3m and can be freely combined through horizontal splicing and vertical stacking (up to 3 floors) to create various floor plans. For example, a rural self-built house can use three modules to form a 90㎡ two-bedroom, one-living room layout, while a cultural tourism homestay can use six modules to create an 180㎡ LOFT structure.

Application Scenarios and Market Conditions

This technological system also includes assembled integral frame structures and shear wall structures, among others, and is widely applied in high-rise residential buildings, commercial offices, and other fields. Prices vary by brand and region in the market. For example, the price of rural villa prefabricated concrete houses from the Xiangyun brand in Jining, Shandong, is 600 yuan per square meter, and users can choose standardized products or customized designs based on their needs.
