Prefabricated Concrete Wall Panel Assembled House

Prefabricated concrete wall panel assembled houses are prefabricated buildings constructed through factory-based production and modular assembly, with prefabricated reinforced concrete modules as the core.

Core Process and Installation Method

This technology adopts the “factory prefabrication + on-site assembly” model: Core components such as walls, floors, and beams are cast in one piece using high-precision molds at specialized production bases. Each module integrates a steel reinforcement framework, insulation layers, waterproofing layers, and pre-embedded piping systems, forming standardized “building blocks.” Taking prefabricated concrete wall panels that can reach several tens of meters in height as an example, during hoisting, multiple sets of hooks are lowered through a multi-point locking system. Workers secure them, and the panels are then smoothly lifted and moved to the predetermined pile positions. Workers below assist in precise placement to ensure seamless connections between modules.

Core Advantages

1. High Efficiency: A single 30㎡ module takes only 7 days for factory prefabrication. During on-site installation, 3 workers working with a crane can complete the installation of a single module in 4 hours. The overall construction of a 100㎡ house takes only 2 days, significantly shortening the construction period.
2. Low Cost: For a 120㎡ self-built rural house, the construction cost of a traditional brick-and-mortar structure is approximately 180,000 - 220,000 yuan, while the cost of the main modules of a concrete house is only 120,000 - 150,000 yuan, reducing the overall cost by 30%. If the leasing model is chosen, the annual rent can be as low as 5,000 yuan per unit.
3. Green and Environmentally Friendly: The factory-based production achieves a 95% recycling rate of off-cuts. There is no dust or sewage discharge at the construction site, and the amount of construction waste is only 10% of that of traditional house construction. Environmentally friendly concrete and water-based paints are used as materials. The formaldehyde emission is ≤0.05mg/m³, far below the national standard (0.1mg/m³), enabling “immediate occupancy after installation.”
4. Excellent Performance: C30 - C40 grade concrete is used, with built-in Φ8 - Φ12 steel reinforcement meshes. The compressive strength reaches 25 - 30MPa, 1.5 times that of traditional brick-and-mortar structures. The walls have pre-reserved slots for EPS insulation layers, improving thermal insulation performance by 40%. The modules are connected through pre-stressed bolts + welded steel plates, with a wind resistance rating of Level 10 and a seismic fortification intensity of Level 7.
5. Flexible House Types: The standard module size is 6m×3m×3m (length, width, and height). House types can be freely combined through horizontal splicing or vertical stacking (up to 3 floors), meeting the diverse needs of self-built rural houses, cultural and tourism homestays, etc.
