Prefabricated Concrete Structure House

Prefabricated concrete structure houses are built with prefabricated components as the core, offering advantages such as efficiency, cost-effectiveness, environmental friendliness, and resistance to earthquakes and wind. They are suitable for rural self-built houses, cultural tourism homestays, and other scenarios.

Technical Parameters and Performance Advantages

The core components of prefabricated concrete structure houses (such as walls, floors, and beams) are cast in factories using high-precision molds, integrating steel reinforcement skeletons, insulation layers, waterproof layers, and pre-embedded pipelines. They use C30-C40 grade concrete with built-in Φ8-Φ12 steel reinforcement mesh, achieving a compressive strength of 25-30 MPa, which is 1.5 times that of traditional brick-and-mortar structures. The walls are designed with EPS insulation layer slots, improving thermal insulation by 40%. They can withstand wind speeds up to Category 10 and have an earthquake resistance rating of 7 degrees (equivalent to the destructive force of the Wenchuan earthquake). Some types, such as prefabricated concrete integrated houses, can resist typhoons up to Category 12.

Construction Efficiency and Cost

The separation of factory prefabrication and on-site installation significantly shortens the construction period. A single 30㎡ module takes 7 days to prefabricate in the factory, and 3 workers with a crane can complete the installation of a single module in 4 hours on-site. A 100㎡ house can be fully constructed in just 2 days, reducing the traditional 3-6 month construction period by over 90%. In terms of cost, the main module cost for a 120㎡ rural self-built house ranges from 120,000 to 150,000 yuan, with total expenses controlled within 200,000 yuan, 30% lower than traditional brick-and-mortar structures. The rental model offers annual rents as low as 5,000 yuan per room. For prefabricated concrete integrated houses, a 200㎡ villa can be constructed in 4 hours, and the main module cost for a 100㎡ house ranges from 100,000 to 120,000 yuan, 30% cheaper than brick-and-mortar structures.

Environmental Protection and Sustainability

Factory production achieves a 95% recycling rate for offcuts and reduces construction waste on-site by 90%. The formaldehyde emission level of the materials is ≤0.05 mg/m³ (national standard: 0.1 mg/m³), allowing for immediate occupancy and reducing environmental pollution.

Modular Design and Application Scenarios

The standard module size is 6m × 3m × 3m, allowing for spatial expansion through horizontal or vertical stacking (up to 3 floors) and supporting free combination of house types. They are suitable for rural self-built houses, cultural tourism homestays, and other scenarios. For example, 2,000 relief houses were constructed in 72 hours during the Gansu Jishishan earthquake, with a simulated displacement of only 3 cm, demonstrating their rapid response and stability.

Precautions

Customized designs (such as rounded balconies) require an additional 20% fee. It is recommended to choose brands that provide a 70-year warranty and earthquake resistance reports to ensure long-term safety and compliance.
