Fully Cement Prefabricated House

A fully cement prefabricated house is an assembled house built with prefabricated reinforced concrete modules as its core, through factory prefabrication and on-site assembly, featuring efficiency, economy, environmental protection, and flexibility.

Core Process and Structural Features

The fully cement prefabricated house adopts a "factory prefabrication + on-site assembly" model, with core components (such as walls, floors, and beams) cast in one piece in the factory using high-precision molds. Each module integrates multiple structures:

• Reinforced Concrete Framework: Utilizing C30-C40 grade concrete with built-in Φ8-Φ12 steel reinforcement mesh, it achieves a compressive strength of 25-30MPa, 1.5 times that of traditional brick-and-mortar structures, significantly enhancing structural stability.
• Insulation and Waterproof Layers: The walls are designed with EPS insulation layer slots, which, when embedded on-site, improve thermal insulation by 40%, ensuring warmth in winter and coolness in summer; simultaneously, an integrated waterproof layer reduces the risk of leakage.
• Pre-embedded Pipelines: Water and electricity pipelines are pre-embedded within the modules, avoiding on-site trenching that could damage the structure, and improving construction efficiency and safety.

Connection Technology and Disaster Resistance

Modules are connected via prestressed bolts + welded steel plates, forming an overall frame structure:

• Wind Resistance: Capable of withstanding strong winds of up to force 10, suitable for coastal or windy regions.
• Earthquake Resistance: Designed to withstand an intensity of 7 degrees, equivalent to the destructive force of the Wenchuan earthquake, it disperses seismic energy through rigid connections, reducing the risk of collapse.

Core Advantages

1. High Efficiency: A single 30㎡ module takes only 7 days for factory prefabrication and just 4 hours for on-site installation (by 3 workers with a crane), with a 100㎡ house taking only 2 days for complete assembly, far faster than the traditional 3-6 month construction period.
2. Low Cost: The cost of the main modules for a 120㎡ house ranges from 120,000 to 150,000 yuan, with the overall construction cost (including decoration) controllable 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, suitable for temporary housing needs.
3. Green and Environmentally Friendly: Factory production achieves a 95% recycling rate of offcuts, with no dust or sewage discharge on-site, and construction waste only 10% of that of traditional construction; environmentally friendly concrete and water-based paints are used, with formaldehyde emissions ≤ 0.05mg/m³ (national standard 0.1mg/m³), enabling "immediate occupancy upon installation".
4. Flexible Space: Standard module dimensions are 6m×3m×3m, allowing free combination of house types through horizontal splicing or vertical stacking (up to 3 floors), meeting diverse needs such as rural self-built houses and cultural tourism homestays.

The fully cement prefabricated house, through industrial production and modular design, balances structural strength, construction efficiency, and environmental performance, representing an important development direction in the modern construction field.
