Changyuan Hoisting Prefabricated House
The Changyuan hoisting prefabricated house is an efficient building form that adopts factory prefabrication and on-site hoisting, featuring superior structural performance, significant economic benefits, and a wide range of application scenarios.
Structural and Performance Advantages
The Changyuan hoisting prefabricated house uses high-grade cement-based materials as its core, with a compressive strength exceeding C30 and an earthquake resistance level meeting the requirements for magnitude 8, ensuring structural safety far superior to traditional buildings. Its double-layer hollow wall design results in a thermal conductivity coefficient below 0.5 w/(m·k), providing better thermal insulation than traditional brick-and-mortar structures and effectively reducing energy consumption. Additionally, the material upgrade path is clear, with the development of nano-silica admixtures set to further enhance the impermeability rating to P12, extending service life. Smart integration technology enables structural health monitoring through embedded sensors, meeting the requirements of the Green Building Evaluation Standard.
Outstanding Economic Benefits
The factory prefabrication model reduces overall costs by 20%-30% compared to cast-in-place structures and shortens construction time by 40%. For example, in Henan, hoisting a 200-square-meter house takes only 4 hours, with a rough construction cost of approximately 60,000 yuan (around 300 yuan per square meter), significantly reducing both time and financial costs.
Diverse Application Scenarios
- Livelihood Projects: It has completed the renovation of dilapidated houses in 17 natural villages in Changyuan County, with an average occupancy satisfaction rate of 92%, demonstrating its livability.
- Temporary Facilities: As the main building for the construction camp of the Zhengzhou-Jinan High-Speed Railway section in Changyuan, it has achieved zero quality complaints, reflecting its rapid deployment and stability.
- Emergency Relief: During the reconstruction after the 2021 Weihui flood disaster, 200 transitional houses were delivered within 48 hours, showcasing its emergency response capabilities.
Policy and Market Support
This technology is included in the Henan Province Promotion Catalog for Prefabricated Buildings and enjoys value-added tax refunds upon collection, with strong policy support. In 2023, Changyuan County's cement prefabricated housing production accounted for 6.8% of the national market share, with the industrial chain scale expected to exceed 1.5 billion yuan by 2025, indicating a broad market outlook.
