Xinhe Cement Prefabricated House

Xinhe cement prefabricated houses refer to new-type assembled reinforced concrete full-frame shear wall structure houses, with factory prefabrication and on-site assembly as the core processes. They have advantages such as high efficiency, cost-effectiveness, and environmental friendliness, but their design flexibility and some performance aspects need to be optimized.

Technical Features

Cement prefabricated houses adopt a factory-based production model, where core components such as walls, floors, beams, and columns are cast in one piece using high-precision molds. Each module integrates a steel reinforcement framework, insulation layer, waterproof layer, and pre-embedded piping system, achieving an integrated design of structure and function. For example, pre-embedded water and electricity piping in the modules reduces on-site trenching operations and improves construction accuracy.

Core Advantages

1. High Construction Efficiency: The separation of factory prefabrication and on-site assembly significantly shortens the construction period. A single 30㎡ module takes only 7 days to produce in the factory. On-site, with the cooperation of 3 workers and a crane, a single module can be installed in 4 hours. A 100㎡ house can be fully erected in just 2 days, with an efficiency 3-5 times that of traditional house construction.
2. Lower Costs: Material and labor costs are significantly reduced. 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 cement house is only 120,000-150,000 yuan, representing a 30% reduction in overall costs.
3. Good Environmental Performance: Factory-based production achieves a 95% recovery rate of off-cuts. There is no dust or sewage discharge at the construction site, and construction waste is only 10% of that generated by traditional methods. Environmentally friendly concrete and water-based paints are used, with formaldehyde emissions ≤ 0.05mg/m³, lower than the national standard (0.1mg/m³), supporting 'immediate occupancy'.
4. Reliable Quality: C30-C40 grade concrete and Φ8-Φ12 steel reinforcement meshes are used, with a compressive strength of 25-30MPa, 1.5 times that of traditional brick-and-mortar structures. Modules are connected through pre-stressed bolts and welded steel plates to form an overall framework, with a wind resistance rating of Level 10 and a seismic fortification intensity of Level 7 (equivalent to the destructive force of the Wenchuan earthquake).
5. Flexible Customization: Supports on-demand adjustment of dimensions and floor plans, suitable for various scenarios such as self-built rural houses, elderly care homes, guesthouses, and construction site dormitories. For example, 3 modules can be combined to form a 90㎡ two-bedroom, one-living room unit, and 6 modules can be assembled into a 180㎡ LOFT structure.

Application Scenarios

Mainly applied in self-built rural houses, commercial spaces, and cultural and tourism projects. In the rural market, economic-type residential houses are the focus, while in the cultural and tourism sector, there is an emphasis on characteristic guesthouses and temporary resettlement houses to meet the demands for rapid construction and low-cost operation.

Existing Shortcomings

Design flexibility is limited, and modular production may result in relatively small adjustments to floor plans. Insulation and heat retention performance need to be optimized, especially in extreme climate regions. The seismic performance in earthquake-prone areas requires further verification and improvement.
