Prefabricated Concrete House

Prefabricated concrete houses are modular buildings centered around prefabricated reinforced concrete modules, utilizing factory production and modular assembly methods. They offer high efficiency, cost-effectiveness, environmental friendliness, superior performance, and flexible layout options.

1. Core Process and Structure
Prefabricated houses are cast in one piece in factories using high-precision molds to form core components such as walls, floors, beams, and columns. Each module integrates a steel reinforcement framework, insulation layers, waterproofing layers, and pre-installed piping systems. For example, standard modules measure 6m×3m×3m (length, width, height), incorporate Φ8-Φ12 steel mesh, use C30-C40 grade concrete, and achieve a compressive strength of 25-30MPa, which is 1.5 times that of traditional brick-and-mortar structures. Modules are connected using pre-stressed bolts and welded steel plates to form an integrated frame structure, capable of withstanding wind speeds up to Category 10 and seismic intensities up to 7 degrees.

2. Efficiency and Cost Advantages
Factory prefabrication significantly shortens construction time: a single 30㎡ module takes only 7 days to produce, and 3 workers with a crane can install a single module in just 4 hours on-site, with a 100㎡ house taking only 2 days to assemble. In terms of cost, for a 120㎡ rural self-built house, the cost of a traditional brick-and-mortar structure is approximately 180,000-220,000 yuan, while the main module cost of a prefabricated house is only 120,000-150,000 yuan, reducing the overall cost by 30%. If opting for a leasing model, the annual rent can be as low as 5,000 yuan per room. Some product prices indicate that fully assembled structural houses sell for about 450 yuan/㎡ and support 48-hour delivery.

3. Green and Environmentally Friendly Features
Factory production achieves a 95% recycling rate for off-cuts, with no dust or sewage emissions at the construction site, and construction waste is only 10% of that from traditional building methods. Environmentally friendly concrete and water-based paints are used, with formaldehyde emissions ≤0.05mg/m³, well below the national standard (0.1mg/m³), supporting "move-in ready" occupancy. Walls are pre-slotted for EPS insulation layers, which, when inserted, improve thermal insulation by 40%, providing significant warmth in winter and coolness in summer.

4. Layout Flexibility and Durability
Modules can be freely combined into various layouts through horizontal splicing or vertical stacking (up to 3 floors). For example, 3 modules can be spliced to form a 90㎡ two-bedroom, one-living-room rural self-built house, while 6 modules can be combined into a 180㎡ LOFT-style cultural tourism homestay. Some products claim a warranty period of up to 70 years, indicating high long-term stability.
