Assembly of Rural Cement Prefabricated Houses

The assembly of rural cement prefabricated houses offers characteristics such as high efficiency, flexibility, cost-effectiveness, and environmental friendliness, as detailed below:

I. Assembly Mode and Speed The "factory production + on-site hoisting" mode is adopted, where core components (walls, floors, beams, and columns) are cast in one piece in the factory using high-precision molds to form standardized "building blocks". A single 30㎡ module can be prefabricated in the factory in just 7 days. After being transported to the site, 3-4 workers, in cooperation 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, which is more than 7% faster than traditional construction methods. A case study of a 200㎡ house in rural Henan shows that the floor modules can be hoisted and fixed in sequence by a crane, completing the main structure in just 4 hours.

II. Module Size and Combination Flexibility The standard module size is 6m×3m×3m (length, width, and height), supporting horizontal splicing and vertical stacking (up to 3 floors), allowing for free combination of house types. For example:

• Rural self-built houses: Three modules can be spliced to form a 90㎡ two-bedroom, one-living-room house with an independent kitchen and bathroom;
• Cultural and tourism homestays: Six modules can be combined to form a 180㎡ LOFT structure with a large terrace and floor-to-ceiling windows;
• Other cases: A 7m×3m module can be horizontally spliced to form a large living room or vertically stacked three floors to become a building. The modular design meets different functional requirements and adapts to diverse architectural scenarios.

III. Connection Method and Structural Safety Modules are connected using prestressed bolts and welded steel plates to form an overall frame structure, with a wind resistance rating of up to 10 and a seismic fortification intensity of 7 degrees (equivalent to the destructive force of the Wenchuan earthquake), ensuring structural stability and safety.

IV. Cost and Cost-Effectiveness Advantages Taking a 120㎡ rural self-built house as an example, the cost of a traditional brick-and-mortar structure is approximately 180,000-220,000 yuan (including labor), while the cost of the cement house's main modules is only 120,000-150,000 yuan. With interior and exterior decoration, the total cost can be controlled within 200,000 yuan, representing a 30% reduction in overall costs. A case study of a 200㎡ house in rural Henan shows that the cost per square meter is only 300 yuan, with a total cost of 60,000 yuan for the entire building and only 50,000 yuan for a single-story house with basic decoration, demonstrating significant cost-effectiveness.

V. Outstanding Environmental Performance Factory production achieves a 95% recycling rate of offcuts, with no dust or sewage discharge at the construction site and only 10% of the construction waste generated by traditional house building. Environmentally friendly concrete and water-based paints are used, with formaldehyde emissions ≤0.05mg/m³, far below the national standard (0.1mg/m³), supporting "immediate occupancy" and meeting the requirements of green buildings.
