Reinforced Concrete Prefabricated Structure House

A reinforced concrete prefabricated structure house is a type of house assembled with prefabricated reinforced concrete modules as its core, offering advantages such as efficiency, cost-effectiveness, and environmental friendliness. It is suitable for scenarios such as rural self-built houses, commercial spaces, and cultural tourism projects.

Technical Principles
This type of house is cast in one piece in a specialized production base using high-precision molds to form core components such as walls, floors, and beams. Each module integrates a steel reinforcement framework, insulation layers, waterproofing layers, and pre-installed piping systems, creating standardized “building blocks” that can be flexibly combined and assembled. For example, standard modules measure 6m × 3m × 3m (length × width × height), with space expansion achieved through horizontal assembly or vertical stacking (up to three floors).

Performance Characteristics

1. Compressive Strength: Utilizing C30-C40 grade concrete with an embedded Φ8-Φ12 steel reinforcement mesh, the compressive strength reaches 25-30 MPa, which is 1.5 times that of traditional brick-and-mortar structures, meeting the load-bearing requirements for multi-story buildings.
2. Thermal Insulation: Walls are designed with slots for EPS insulation panels, which, when inserted on-site, improve thermal insulation performance by 40%, effectively reducing energy consumption for heating in winter and cooling in summer.
3. Wind and Earthquake Resistance: Modules are connected using pre-stressed bolts and welded steel plates, forming an integrated frame structure. This design achieves a wind resistance rating of up to Level 10 and an earthquake resistance rating of Intensity 7 (equivalent to the destructive force of the Wenchuan earthquake), making it suitable for earthquake-prone areas.

Core Advantages

1. High Efficiency: A single 30㎡ module can be prefabricated in the factory in just 7 days, with on-site hoisting and installation of a single module taking only 4 hours. A 100㎡ house can be fully constructed in just 2 days, reducing the construction period by over 80% compared to traditional methods.
2. Low Cost: For a 120㎡ rural self-built house, the cost of the main modules ranges from 120,000 to 150,000 yuan, with the overall construction cost being 30% lower than that of traditional brick-and-mortar structures. The leasing model offers annual rents as low as 5,000 yuan per room, further reducing initial investment.
3. Green and Environmentally Friendly: Factory production achieves a 95% recycling rate for off-cuts, with no dust or sewage emissions on-site. Construction waste is only 10% of that generated by traditional construction methods. The formaldehyde emission level of materials is ≤0.05 mg/m³, well below the national standard of 0.1 mg/m³, allowing for “immediate occupancy” upon completion.
4. Flexible Layout: Module combinations can create a 90㎡ two-bedroom, one-living-room layout (by assembling three modules) or an 180㎡ LOFT-style guesthouse (by combining six modules), supporting personalized designs such as independent kitchens, bathrooms, and large terraces.

Application Scenarios
With its rapid construction and cost-effective features, this structure has become the preferred solution for rural self-built houses, commercial temporary buildings, and cultural tourism guesthouse projects, particularly widely promoted in regions such as Henan.
