Prefabricated Assembly Houses in Yuzhou City
Yuzhou City has developed a comprehensive system for the advancement of prefabricated assembly houses, encompassing policy guidance, industrial cultivation, application promotion, and technological integration, achieving remarkable results.
Policy Support and Goal Planning
The Yuzhou City government has issued implementation opinions, explicitly designating prefabricated buildings as the core direction for the transformation and upgrading of the construction industry, with a focus on developing prefabricated concrete buildings and steel structures. The policy proposes gradually increasing the proportion of prefabricated buildings in new constructions, promoting innovation in construction methods, and setting the goal of establishing itself as a benchmark for modern construction industry demonstration cities across the province and even the country. Additionally, after being selected as a demonstration city for prefabricated buildings in Henan Province, Yuzhou has received policy preferences such as priority in arranging construction land and expanding the scope of special fund support, providing strong guarantees for industrial development.
Industrial Base and Leading Enterprise Cultivation
In terms of production base construction, Yuzhou focuses on the development of green prefabricated building industrial bases. By prioritizing the support and cultivation of leading enterprises, it advances key aspects such as design standardization, production industrialization, and construction assembly. For example, some enterprises have achieved large-scale production of prefabricated components in factories, using reinforced concrete materials and casting through standardized molds to ensure component precision and quality. This model not only enhances production efficiency but also lays the foundation for rapid on-site assembly.
Application Scenarios and Market Promotion
Since 2019, Yuzhou has mandated that all government-invested or -led projects (such as affordable housing and shantytown renovations) adopt prefabricated buildings and encourages the implementation of prefabricated technology in newly built commercial housing projects. In the self-built housing sector, prefabricated technology is transitioning from traditional scattered labor models to standardized systems, offering new choices for returnees and local residents seeking improved housing. For instance, a locally produced prefabricated house in Henan integrates full cast-in-place technology with prefabricated techniques, allowing a 200-square-meter main house to be assembled in as little as 4 hours, with a basic rough unit price of approximately 300 yuan per square meter and a standard service life of 70 years, significantly shortening construction time and reducing costs.
Technological Advantages and Considerations
The core advantages of prefabricated houses lie in their short construction time, transparent costs, and controllable quality. However, attention should be paid to the following details:
- Geological Adaptability: Appropriate foundation types (such as strip foundations or independent foundations) should be selected based on the geological conditions of the building site.
- Seismic Design Level: Compliance with local seismic design codes is essential to ensure structural safety.
- Construction Team Expertise: Enterprises with experience in prefabricated construction should be selected to avoid quality issues arising from improper operations.
Currently, Yuzhou's prefabricated building industry has formed a closed loop of 'policy-industry-application-technology,' providing a replicable model for the modernization of the construction industry.
