Prefabricated Reinforced Concrete House

The prefabricated reinforced concrete house is an assembled reinforced concrete structure built through factory prefabrication and on-site assembly, offering advantages such as high efficiency, low cost, and environmental friendliness, suitable for various scenarios.

Core Process and Performance

The prefabricated reinforced concrete house uses high-precision molds to cast core components such as walls, floors, and beams in one go at the factory. Each module integrates multiple structures including a steel reinforcement framework, insulation layers, waterproof layers, and pre-embedded pipelines. For example, it uses C30-C40 grade concrete with an internal Φ8-Φ12 steel reinforcement mesh, achieving a compressive strength of 25-30MPa, which is 1.5 times that of traditional brick-and-mortar structures. The walls have reserved slots for EPS insulation layers, which, when inserted on-site, improve thermal insulation by 40%, providing significant warmth in winter and coolness in summer. The modules are connected using pre-stressed bolts and welded steel plates to form an integrated framework, withstanding wind speeds up to Category 10 and seismic intensity of 7 degrees (equivalent to the destructive force of the Wenchuan earthquake).

Advantages and Characteristics

1. High Efficiency: A single 30㎡ module can be prefabricated in the factory in just 7 days. During on-site installation, three workers with a crane can complete the installation of a single module in 4 hours, and the entire construction of a 100㎡ house takes only 2 days.
2. Low Cost: Taking a 120㎡ self-built rural house as an example, the cost of a traditional brick-and-mortar structure is approximately 180,000-220,000 yuan, while the cost of the main modules of a prefabricated concrete house is only 120,000-150,000 yuan, reducing the overall cost by 30%. The rental model offers an annual rent as low as 5,000 yuan per room, further lowering the barrier to use.
3. Green and Environmentally Friendly: Factory production achieves a 95% recycling rate of offcuts, with no dust or sewage discharge at the construction site, and construction waste is only 10% of that of traditional construction. Environmentally friendly concrete and water-based paints are used, with formaldehyde emissions ≤0.05mg/m³, well below the national standard (0.1mg/m³), enabling 'immediate occupancy upon installation'.
4. Excellent Performance: It possesses multiple properties such as earthquake and compression resistance, fire and flame retardancy, thermal insulation and energy efficiency, wind and moisture resistance, and corrosion and weathering resistance. The design service life is over 70 years, supporting overall relocation and secondary disassembly and reuse.

Scope of Application

It can be used to build office buildings, small hotels, staff dormitories, canteens and restaurants, private garages, storage warehouses, etc. It is widely applicable to scenarios such as rural dilapidated house renovation, rural self-built housing, farm supporting housing, temporary office and accommodation for construction sites, and temporary supporting housing for engineering projects.
