Hefei Housing Prefabricated Components
The following is information about housing prefabricated components in Hefei:
Manufacturing Enterprises and Products: There is a PC component factory in Feidong, Hefei, which offers a wide range of main products, including prefabricated concrete beams, truss composite slabs, PC building components, prefabricated concrete columns, PC prefabricated components, small prefabricated components, BIM composite slabs, prefabricated hollow slab beams, and cement prefabricated stairs. These products are widely used in multiple regions of Hefei, such as Changfeng County, Lujiang County, Feixi County, Yaohai District, Feidong County, and Luyang District, providing high-quality prefabricated component support for the local construction industry.
Assembly Rate Calculation Method: Based on the 'Evaluation Standard for Prefabricated Buildings (GB/T 51129 - 2017)' and related documents, and combined with local development realities, Hefei has formulated an assembly rate calculation method. This method is applicable to prefabricated concrete structures, steel structures, and hybrid-structure buildings, with wooden-structure buildings able to refer to it for implementation. The assembly rate calculation formula comprehensively considers the combined proportion of prefabricated parts and components used in the main structure, enclosure walls and interior partition walls, decoration, and equipment pipelines. It calculates through a series of indicator scores to evaluate the degree of prefabrication of the building.
Production Information Collection and Update Results: In 2024, Hefei collected and updated production information on prefabricated concrete components for prefabricated buildings. The results showed that there were 5 Grade-A enterprises, 23 Grade-B enterprises, and 2 Grade-C enterprises. This result reflects the overall level and quality status of prefabricated component manufacturing enterprises in Hefei, providing an important reference for industry management and market selection.
Relevant Standards and Management: In terms of industry management for prefabricated components, Hefei strictly implements the building industry standard 'Prefabricated Concrete Components for Prefabricated Buildings' and has issued supporting documents such as the 'Standardization Construction and Evaluation Manual for Manufacturing Enterprises' and the 'Laboratory Management Guidelines' to refine implementation requirements in areas such as production processes and laboratory management. Additionally, through special quality management notices, it has clarified systems such as on-site supervision during manufacturing and site acceptance, strengthened quality traceability management for manufacturing enterprises, and formed a management system that links industry standards with local regulations.
