Shangshui Cement Prefabricated House

Shangshui cement prefabricated houses are a form of construction that uses cement, sand, gravel, and steel bars as the main materials. These components are prefabricated in factories and then assembled on-site, offering advantages such as fast construction, low cost, and excellent performance. They are suitable for various fields including commercial, residential, temporary housing, emergency relief, and cultural tourism. However, they have limitations in terms of personalized space layout and relatively poor sound insulation and thermal insulation of walls.

Materials and Structure: Using cement, sand, and gravel as the base materials, steel bars enhance tensile strength. The structures adopt either a frame system (beam-column combination) or a slab system (prefabricated slab assembly) to ensure building stability. For example, frame structures bear loads through beams and columns, while slab systems are suitable for small-span buildings.

Manufacturing Process: The process includes six stages: design, mold making, concrete mixing, pouring and vibration, curing, transportation, and assembly. Factory-prefabricated components allow for strict quality control, and on-site assembly uses lifting equipment for precise positioning and secure connections. For instance, a 100㎡ house can complete module production in 7 days and assembly in 2 days, significantly shorter than traditional brick-and-mortar construction.

Advantages:

• High Construction Efficiency: Combining factory prefabrication with on-site assembly, the construction period for a 100㎡ house is reduced from 3-6 months to just 9 days, significantly improving efficiency.
• Cost Control: Factory production reduces material waste, lowering the main structure cost of a 120㎡ rural self-built house from 180,000-220,000 yuan to 120,000-150,000 yuan, saving nearly one-third overall.
• Superior Performance: Using C30-C40 concrete and steel mesh, the compressive strength reaches 25-30MPa, withstanding an earthquake intensity of 7 degrees and wind speeds of up to 10 levels. EPS insulation layers improve thermal insulation by 40%, ensuring warmth in winter and coolness in summer.
• Flexibility: Modules can be disassembled and reassembled, adapting to changes in commercial use. For example, relocating a photography studio takes only 1 day and costs 20,000 yuan, saving 70% of the cost.
• Environmental Friendliness: Factory scrap recovery rate reaches 95%, with no dust or sewage on-site. Environmentally friendly concrete and water-based paints keep formaldehyde levels ≤0.05mg/m³, enabling "move-in ready" conditions.
• Diverse Design: Modules support horizontal and vertical stacking, enabling various floor plans such as a 90㎡ two-bedroom apartment or an 180㎡ LOFT-style homestay. Exterior finishes use stone-like paint and 3D-printed reliefs for rich visual effects.

Disadvantages:

• Limited Space Personalization: Modular design results in insufficient detail handling, making it difficult to meet complex functional layout requirements.
• Sound Insulation and Thermal Insulation to Be Improved: Walls are relatively thin, requiring additional insulation layers in cold regions. Cracks at connections can affect sound insulation.
• Stability Risks in High-Rise Buildings: Assembled structures above three floors have connection and fixation issues. Grouting joint construction requires professional teams, and rural self-built houses may face safety hazards due to insufficient technical expertise.

Application Scenarios:

• Commercial Sector: Office buildings, small hotels, staff dormitories, etc.
• Residential Sector: Rural dilapidated house renovations, rural self-built housing.
• Temporary Housing: Construction site offices and accommodations, project support buildings.
• Emergency Relief: Temporary disaster relief shelters (e.g., 200 sets erected in 3 days after the Zhengzhou rainstorm).
• Cultural Tourism: Movable homestays (e.g., Moganshan homestays that relocate seasonally, increasing annual reception by 40%).
