Prefabricated House Assembly in Anhui
The prefabrication of houses in Anhui is mainly reflected in aspects such as corporate innovation, system characteristics, factory prefabrication, construction processes, and application scenarios.
Corporate Innovation: Anhui Huiliao has delved deeply into ultra-high-strength concrete (UHPC) prefabricated construction, developing integrated UHPC wall panels that combine structural, thermal insulation, and decorative functions for modular and intelligent prefabricated buildings. These wall panels offer significant advantages, weighing only 120 to 150 kilograms per square meter, which is just one-fourth of the weight of traditional wall panels; their compressive strength exceeds 130MPa, more than four times that of ordinary concrete; and their water absorption rate is below 1%, with a designed service life of 70 to 100 years.
System Characteristics: Anhui Construction Engineering Group has introduced a prefabricated steel structure building system that deeply integrates the performance advantages of steel structures with the characteristics of prefabricated technology, guided by the principles of “standardized design, industrial production, digital management, and green construction”. The houses are composed of prefabricated foundations, assembled steel frames, prefabricated floor slabs, lightweight wall panels, and integrated roofs, with all parts working in harmony to ensure the overall performance of the building.
Factory Prefabrication: Anhui Construction Engineering Group's intelligent manufacturing plant in Changfeng covers an area of 327 acres, with intelligent welding lines, intelligent sheet metal cutting centers, and intelligent spraying lines operating in an orderly manner. The base can produce up to 10,000 typical two-story houses annually. Every steel beam and wall panel is processed under digital management, achieving millimeter-level precision in components. Each component undergoes standardized design and industrial production, and is assigned a traceable quality file on the assembly line, ensuring the quality and consistency of the components.
Construction Processes: After the components are transported to the construction site, the main structure is connected using full bolts, eliminating the need for wet work and generating almost no construction waste. The entire construction process is simple, efficient, precise, and controllable, with component installation errors strictly controlled at the millimeter level. For example, a two-story residential house can be assembled in just 15 days, and ready for occupancy in 30 days, significantly shortening the construction period.
Application Scenarios: Anhui Construction Engineering Group provides a one-stop comprehensive service from design, production, installation, to operation and maintenance, covering a diverse range of scenarios such as self-built houses on homesteads, rural homestays, affordable housing, talent apartments, schools and hospitals, emergency medical facilities, and supporting facilities for highway service areas. At the resettlement site in Kongwei Village, Shuihu Town, Changfeng County, Hefei, a layered prefabricated steel structure building system is adopted, achieving a prefabrication rate of 100%. It can also flexibly design different floor plans for the upper and lower floors according to the needs of residents.
