Baishan Cement Prefabricated House

The Baishan cement prefabricated house is a building form centered around prefabricated concrete components, achieved through standardized factory production and rapid on-site assembly. It features efficient structure, reliable performance, and low cost, but it is important to choose a modular system that meets modern standards.

Technical Features and Structural Advantages

Prefabricated concrete components are the core material of the Baishan cement prefabricated house. Their surface textures and joint treatments form repetitive visual units that not only reflect the precision of material craftsmanship but also reveal the load-bearing logic through exposed support systems, creating a clear internal spatial order. Modern technology has broken through traditional limitations. For example, the project in Qixian, Henan, adopts a full-frame shear wall structure with a single-module reinforcement ratio of 1.2%, a wall thickness of 200mm, and a compressive strength of 30MPa, achieving a 9-degree seismic resistance through a combination of mortise-and-tenon and bolt connections. Field tests in Yangjiang, Guangdong, show that such houses can withstand typhoons of up to Category 12, with no脱落 (tuōluò,脱落 means peeling off) of exterior wall tiles and a deformation of less than 1mm in doors and windows. These data indicate that prefabricated houses have reached high standards in structural safety and durability.

Cost and Efficiency Advantages

Prefabrication technology significantly outperforms traditional construction methods. For a 100㎡ house, labor costs can be reduced by 60%, and construction waste by 98%. During the COVID-19 pandemic in Shenzhen, 300 quarantine wards were built in just 48 hours. In rural market applications, the cost per square meter of prefabricated houses is only around 300 yuan, with a villa costing just over 100,000 yuan and the main structure installation taking only 4 hours. This efficiency stems from the synergy between standardized factory production and on-site modular assembly, greatly shortening the construction period and reducing the complexity of on-site operations.

Early Limitations and Improvement Directions

Early rural cement prefabricated panel houses had hidden dangers such as poor sound insulation and water leakage due to gaps between panels, as well as insufficient seismic resistance, and have gradually been replaced by cast-in-place structures. If prefabrication technology is adopted in the Baishan region today, priority should be given to selecting modular systems that have passed seismic tests and ensuring that joint treatments meet modern industrial standards. For example, measures such as adopting a combination of mortise-and-tenon and bolt connections, optimizing joint waterproofing designs, and increasing reinforcement ratios can effectively improve the seismic resistance, sound insulation, and waterproofing performance of houses.
