How to Build a Cement Prefabricated Panel House

The construction of a cement prefabricated panel house involves four stages: preparation, production, on-site assembly and construction, and post-construction maintenance. The specific steps are as follows:

1. Preparation Stage

• Site Selection and Evaluation: Ensure that the construction site has stable geology (e.g., avoiding soft soil and landslide-prone areas), a suitable surrounding environment (e.g., away from pollution sources and flood risk areas), and complies with local building planning requirements.
• Design Plan Development: Design the house structure (e.g., single-story or multi-story), layout (e.g., room distribution and door/window positions), and load requirements based on living needs. Specify the dimensions, quantities, and connection methods of the prefabricated components.
• Material and Equipment Preparation: Purchase raw materials such as cement, steel bars, and sand and gravel, ensuring they meet national standards (e.g., cement strength grade and steel bar diameter). Prepare molds (for shaping prefabricated components), connectors (e.g., bolts and welding materials), and construction machinery (e.g., cranes and vibrators).
• Safety Training: Provide safety operation training for construction personnel, including protection for high-altitude work, electrical safety, and emergency response measures, to ensure compliance with safety regulations during construction.

2. Component Production

• Mold Making and Concrete Pouring: Make molds according to the design dimensions in the factory. Pour concrete (containing cement, sand and gravel, water, and additives) into the molds. Use a vibrator to remove air bubbles and ensure density, then smooth the surface with a finishing tool.
• Curing and Polishing: After the concrete solidifies, remove the molds and water the components for curing (usually 7-14 days) to prevent cracking. After curing, polish the edges to ensure dimensional accuracy (with an error controlled within ±2mm).
• Quality Inspection: Conduct compression and flexural tests on the components. Check the thickness of the steel bar protective layer and the positions of embedded parts to ensure compliance with design load requirements. Also, calibrate the levelness of each module for easy subsequent assembly.

3. On-Site Assembly and Construction

• Foundation Pouring: Excavate foundation pits at the selected site, lay a steel bar mesh, and pour concrete to form a solid foundation (e.g., strip foundation or raft foundation), ensuring the bearing capacity meets the weight of the house.
• Component Transportation and Hoisting: Transport prefabricated walls, floor slabs, and other components to the site. Use a crane to hoist them to the designated positions in the designed order. Connect them through bolts, welding, or mortise-and-tenon joints to form an overall framework.
• Facility Installation: After the main structure is completed, install distribution boxes, switches and sockets, water pipes, and sewer pipes, ensuring that the electrical and water lines are concealed and comply with safety standards. Lay the roof waterproof layer and insulation materials.
• Acceptance and Adjustment: Check the verticality (with an error ≤ H/1000, where H is the house height), flatness, and connection firmness of the house. Make local adjustments to ensure structural safety and stability.

4. Post-Construction Maintenance and Management

• Regular Inspection: Inspect the house structure (e.g., wall cracks and connector rust) and electrical and water facilities (e.g., pipe leakage and circuit aging) every 1-2 years, and promptly repair any problems.
• Cleaning and Maintenance: Regularly clean the roof drainage ditches to prevent blockage. Apply anti-rust paint to metal connectors to extend their service life.
• Functional Upgrades: Add insulation layers, solar equipment, etc., according to needs to improve living comfort and energy efficiency.
