Baiyin Rural Prefabricated House Assembly

The assembly of prefabricated houses in rural areas of Baiyin mainly includes three types: prefabricated floor slabs, prefabricated composite floor slabs, and box-type houses, each with its own characteristics and applicable scenarios.

Prefabricated Floor Slab Assembly

• Cost and Price: The price of factory-direct prefabricated floor slabs is 10%-15% lower than the market price. The factory-direct price for a 120mm-thick slab is approximately 80 - 100 yuan per square meter.
• Advantages: Stable quality, as they are produced in a standardized factory environment with strict ratios of steel bars and concrete, ensuring strength and thickness, and reducing the risk of cracking and leakage; fast construction speed, as they can be directly installed on-site after delivery, which is 3 - 5 days faster than on-site pouring, shortening the overall project duration; environmentally friendly and energy-saving, as factory production reduces on-site dust and noise, meeting environmental requirements and enhancing safety.
• Key Points for Selecting a Factory: Check the factory's qualifications; a legitimate factory should have a production license, quality inspection reports, and be able to provide product certificates; conduct on-site inspections of the factory's equipment, raw material storage, and production processes; understand after-sales services; good manufacturers will provide transportation, installation guidance, and even warranty services, such as promising to replace floor slabs free of charge if quality issues arise.
• Applicable Scenarios: Suitable for rural self-built houses, small shops, warehouses, and other buildings.

Prefabricated Composite Floor Slab Assembly

• Material Characteristics: Made of concrete with a strength of C30 or higher, with anti-crack treatment on the surface to adapt to the dry environment of Baiyin and reduce the risk of cracks; the spacing of steel bar trusses is strictly controlled within 150mm to enhance overall load-bearing stability.
• Key Advantages: Shortens the construction period, saving 40% of the installation time compared to traditional cast-in-place floor slabs, suitable for projects with tight schedules; reduces labor costs, as only simple splicing and lifting are required on-site, reducing procedures such as steel bar binding; environmentally friendly and energy-saving, as prefabricated components reduce on-site wet operations, meeting Baiyin's environmental construction requirements.
• Installation Key Points: Apply a special interface agent at the slab joints to enhance integrity; the lifting equipment must match the weight of the floor slabs and strictly follow the lifting plan; the grout fullness inspection should be completed within 24 hours to ensure structural strength.
• Quality Control and Acceptance Standards: Before leaving the factory, they must pass three inspections: concrete strength, steel bar protective layer thickness, and embedded part position deviation; on-site acceptance should focus on checking the flatness of the joints and the deflection of the floor slabs, with errors controlled within the specified range.

Box-Type House Assembly

Box-type houses are prefabricated assembled buildings, with main components produced in the factory and then transported to the site for rapid assembly. Specific structural characteristics and application scenarios can be referred to the above content.
