Sichuan Prefabricated Cement Integrated House

The Sichuan prefabricated cement integrated house is an assembled house centered around prefabricated reinforced concrete modules, utilizing factory-based production and modular assembly methods, characterized by high efficiency, cost-effectiveness, environmental friendliness, and excellent performance.

Core Process and Structure
This house is cast in one piece in a factory using high-precision molds to form core components such as walls, floors, beams, and columns. Each module integrates a steel reinforcement framework, insulation layer, waterproof layer, and pre-installed piping system. With module dimensions of 6m×3m×3m (length, width, height),户型自由组合 (free layout combinations) can be achieved through horizontal splicing or vertical stacking (up to three floors), making it suitable for rural self-built houses, cultural tourism homestays, and other scenarios.

Performance Advantages

• Efficient Construction: A single 30㎡ module takes only 7 days for factory prefabrication. On-site, three workers with a crane can install a single module in 4 hours, and the entire 100㎡ house can be erected in just 2 days.
• Cost Control: For a 120㎡ rural self-built house, the traditional brick-and-mortar structure costs approximately 180,000-220,000 yuan, while the cement house's main module costs only 120,000-150,000 yuan, reducing the overall cost by 30%. In a rental model, the annual rent can be as low as 5,000 yuan per room.
• Green and Environmentally Friendly: Factory production achieves a 95% recycling rate for offcuts, with no dust or sewage emissions on-site. Construction waste is only 10% of that from traditional construction. Environmentally friendly concrete and water-based paints are used, with formaldehyde emissions ≤0.05mg/m³ (national standard is 0.1mg/m³), enabling "immediate occupancy" upon completion.
• Structural Safety: Utilizing C30-C40 grade concrete with built-in Φ8-Φ12 steel reinforcement mesh, the compressive strength reaches 25-30MPa (1.5 times that of traditional brick-and-mortar structures). Walls are pre-slotted for EPS insulation layers, improving thermal insulation by 40%. Modules are connected via pre-stressed bolts and welded steel plates, withstanding wind speeds up to grade 10 and seismic intensity of 7 degrees (equivalent to the destructive force of the Wenchuan earthquake), featuring fire, moisture, and corrosion resistance.
• Longevity and Flexibility: Designed for a service life exceeding 70 years, the house supports overall relocation and secondary disassembly for reuse, with low maintenance costs.

Price and Suitable Scenarios
Prices vary by brand and region. For example, assembled cement box houses in Dazhou, Sichuan, cost 1,100 yuan per square meter, locally shipped cement houses in Chengdu range from 300-1,200 yuan per square meter, and prefabricated cement houses in Bazhong cost 1,000 yuan per square meter. They can be applied to office buildings, small hotels, staff dormitories, storage warehouses, etc., and are widely suitable for rural dilapidated house renovations, rural self-built housing, and temporary housing on construction sites.
