Prefabricated Concrete House Structure

Prefabricated concrete house structure mainly refers to prefabricated reinforced concrete full-frame shear wall structure houses, with the core process being factory prefabrication and on-site assembly. It achieves efficient construction through modular design, with the following specific characteristics:

1. Significant structural performance advantages
It uses C30-C40 grade concrete with built-in Φ8-Φ12 steel reinforcement mesh, forming a high-strength composite structure with a compressive strength of 25-30MPa, which is 1.5 times that of traditional brick-concrete structures. The walls have reserved slots for EPS insulation layers, and after on-site insertion, the thermal insulation performance is improved by 40%, effectively reducing energy consumption. The modules are connected through prestressed bolts and welded steel plates to form an overall frame, with a wind resistance rating of Level 10 and a seismic fortification intensity of Level 7 (capable of withstanding the destructive force of the Wenchuan earthquake), suitable for earthquake-prone zones and strong wind areas.

2. Factory production ensures precision
In specialized production bases, high-precision molds are used to cast core components such as walls, floors, beams, and columns in one go. Each module integrates a steel reinforcement framework, insulation layer, waterproof layer, and pre-embedded piping system, enabling flexible combination like "building blocks". Factory production eliminates on-site construction errors, with component dimensional deviations controlled within millimeters, ensuring overall structural stability and safety.

3. Modular classification meets diverse needs
It can be divided into five categories based on purpose and structure:

• Rural self-built houses: Standardized modules for rapid assembly, meeting basic living needs;
• Rural villas: Customized designs for personalized appearance and functional layout;
• Prefabricated courtyard walls/concrete gates: Lightweight modules that balance safety and aesthetics;
• Commercial buildings: Such as office buildings and hotels, which use large-span modules to achieve column-free space design and improve utilization efficiency.

4. Outstanding construction efficiency and environmental protection
On-site work only requires component assembly, shortening the construction period by more than 50% compared to traditional buildings and reducing dust and noise pollution from wet operations. The reusable and reconfigurable nature of the modules supports building function iteration, with a material recycling rate of over 80%, aligning with the trend of green building development.

This structure balances efficiency, cost, and performance through industrial production and standardized connection technologies, becoming an important development direction in the modern construction field.
