Nanchang Prefabricated Assembly House

The development of prefabricated assembly houses in Nanchang has been rapid, achieving remarkable results in policies, construction methods, advantages, application scopes, and industrial development.

Strong Policy Support: Nanchang actively promotes the development of prefabricated buildings. Newly started housing construction projects funded by the government are required to adopt prefabricated technology 100%, and eligible municipal infrastructure projects must also fully adopt it. The Municipal Housing and Urban-Rural Development Bureau has issued notices clarifying the responsibilities of participating units and strengthening quality and safety supervision to provide institutional guarantees for industrial development.

Standardized Construction Methods: The factory-prefabricated component and on-site assembly model is adopted. Walls, floor slabs, and other components are produced in factories and then transported to construction sites for assembly. Node strength is enhanced through steel-reinforced concrete connections and pouring. The main structural types include prefabricated concrete structures, steel structures, and modern timber structures, suitable for general civil buildings, except for those with high seismic requirements or complex structures.

Prominent Advantages:

• Quality Control: Factory production reduces human errors and demonstrates significant energy-saving and green characteristics.
• Adaptation to Special Environments: In response to Nanchang's humid and rainy climate and large temperature differences between winter and summer, moisture-proof materials, phase-change temperature regulation technology, and double-layer ventilated walls are used to effectively prevent mildew and corrosion and improve thermal comfort.
• Flexible Design: Modular design can adapt to mountainous and waterfront terrains. Installation does not require large machinery, making it suitable for areas with inconvenient transportation.
• Environmental Protection and Energy Efficiency: Integrated solar energy and rainwater harvesting systems are used, and local procurement reduces transportation energy consumption.

Wide Application Scope: Prefabricated buildings account for 30% of the total construction area in Nanchang, covering factory buildings, office buildings, residential communities, and teaching buildings. Applicable scenarios include residential buildings (houses, apartments, etc.), public buildings (offices, hospitals, etc.), industrial buildings (factories, warehouses), and municipal facilities (subway segments, utility tunnels, etc.).

Industrial Agglomeration: Enterprises such as Jiangxi Lvdao Integrated Construction Technology Co., Ltd. lead the industry, possessing lightweight steel structure systems and digital management platforms. Their products have passed ISO9001 certification and are applied in new rural construction, tourist attractions, and emergency shelters. Nanchang is leveraging its geographical and ecological advantages to build a green building supply base in central China.
