Prefabricated Cement House Construction

Prefabricated cement house construction is an assembly-type building model that utilizes standardized factory production and on-site assembly construction, featuring efficiency, cost-effectiveness, reliability, and environmental friendliness.

Technical Principles and Structural Features

The full name of a prefabricated cement house is an "assembly-type reinforced concrete full-frame shear wall structure house." Its core components, such as walls, floors, and beams and columns, are cast in one piece in the factory using high-precision molds. Each module integrates a steel reinforcement framework, insulation layer, waterproof layer, and pre-installed piping system, using C30-C40 grade concrete with built-in Φ8-Φ12 steel reinforcement mesh, achieving a compressive strength of 25-30MPa, which is 1.5 times that of traditional brick-and-mortar structures. Modules are connected through prestressed bolts and welded steel plates to form an overall frame structure, ensuring wind resistance up to Level 10 and seismic resistance up to Intensity 7 (capable of withstanding the destructive force of the Wenchuan earthquake).

Core Advantages

1. High Efficiency: A single 30㎡ module can be prefabricated in the factory in just 7 days, and on-site installation of a single module can be completed by 3 workers with a crane in 4 hours, with the overall construction of a 100㎡ house taking only 2 days. For example, in a case in Sichuan, the main structure of a 200㎡ house cost only 110,000 yuan, and the "one-day production, on-site assembly" model significantly shortened the construction period.
2. Low Cost: 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, while the cost of the main modules of a prefabricated cement house is only 120,000-150,000 yuan, reducing the overall cost by 30%.
3. Reliable Quality: Standardized factory production eliminates manual errors, and the modules have high connection strength, with durability reaching the standard of "a house that can be passed down for three generations."
4. Environmental Protection and Energy Efficiency: Factory production reduces construction waste by 90%, and materials are selected from environmentally friendly concrete and water-based paints, with formaldehyde emissions ≤0.05mg/m³, well below national standards.

Application Scenarios

1. Rural Self-Built Houses: Economical and practical, with outstanding moisture resistance, meeting basic living needs.
2. Rural Villas: Supporting floor heights of 3.3 meters or 3.6 meters, enhancing exterior design and spatial layout to improve living comfort.
3. Commercial Buildings: Such as office buildings and hotels, widely used in homestays and small commercial buildings due to their large-span advantages and rapid construction characteristics.

Typical Cases

Shandong Good House Rural Villa Building Materials Technology Co., Ltd. provides integrated services for prefabricated cement houses, courtyard walls, gates, and foundation bases, covering the entire area of Zibo City; in the case of Sichuan Fubainian Cement Houses, the main structure of a 200㎡ house cost 110,000 yuan, emphasizing seismic resistance and durability.

Construction Process

Reinforcement tying, formwork assembly, concrete pouring, and steam curing are completed in the factory, with demolding and hoisting the next day; on-site construction only requires modular assembly, with no wet operations required throughout the process, significantly reducing weather dependence.
