Anhui Prefabricated House Construction

Anhui prefabricated house construction primarily adopts prefabricated integrated housing and prefabricated building forms, characterized by short construction periods, controllable quality, and environmental protection and energy efficiency. It is widely applied in areas such as rural revitalization, temporary resettlement, cultural tourism homestays, and supporting facilities in industrial parks.

Technical Systems and Structural Forms

Anhui prefabricated house construction mainly relies on light steel structures or concrete prefabricated panel systems. The light steel structure system boasts excellent fire resistance, earthquake resistance, and thermal insulation performance, making it suitable for various scenarios. The concrete prefabricated panel system ensures component precision and quality stability through standardized factory production. Some enterprises have introduced BIM (Building Information Modeling) technology to achieve digital management throughout the design, production, and construction processes, enhancing collaboration efficiency. In response to the local humid and hot climate, products have undergone special optimizations in moisture resistance, ventilation, and roof drainage. For example, breathable wall structures are used to enhance air circulation, and pitched roofs are designed to accelerate rainwater drainage, ensuring structural safety and living comfort during long-term use.

Typical Cases and Technological Breakthroughs

• Mengcheng County's "Wanmei Good Rural Houses" Project: Taking Xiangshan Village as a pilot, the project adopts prefabricated frame structures and brick-concrete houses, with wall panels, floor slabs, stairs, and other components prefabricated in factories and assembled on-site. Through the "Five Goods and One Strict" system (good standards, good design, good materials, good construction, good cost, and strict supervision), the construction period has been shortened to 2 months for rough-finished houses and 4 months for fully furnished houses, significantly improving rural housing construction efficiency.
• Anhui Construction Engineering's Prefabricated Steel Structure System: This system achieves integrated collaboration in "design-production-installation" and is 100% fully prefabricated. Its intelligent manufacturing factory produces 10,000 typical two-story houses annually, with component precision reaching the millimeter level. The main structure is fully bolted, eliminating the need for wet work and generating nearly zero construction waste. The system meets seismic fortification requirements of over 8 degrees, with steel components that can be 100% disassembled and recycled, and enclosure materials with a reuse rate of up to 80%, combining environmental protection with economic efficiency.

Policy Support and Large-Scale Application

Since 2020, Anhui has been promoting the popularization of prefabricated buildings, explicitly requiring that all newly built affordable housing, talent apartments, and public buildings with government investments exceeding 100,000 square meters in Hefei adopt prefabricated technology. In 2024, the province's largest prefabricated resettlement housing project—the third phase of Modian Jiayuan—was completed and delivered. It adopts an integrated prefabricated concrete shear wall system with an assembly rate exceeding 50%, receiving positive feedback from residents and verifying the technological maturity and market acceptance.
