Nanjing Prefabricated Assembled Houses

Nanjing prefabricated assembled houses are industrial buildings constructed using a factory-prefabricated, on-site-assembled model, characterized by efficiency, flexibility, and environmental friendliness, suitable for various scenarios.

Technical Features and Material Performance

Nanjing prefabricated assembled houses are centered around standardized design, factory-based production, assembly-based construction, and integrated decoration. They utilize BIM technology to achieve full lifecycle data collaboration, with component precision reaching millimeter levels, reducing on-site wet operations. The structural system adopts a modular design, supporting flexible combinations and future expansions. The walls integrate insulation, soundproofing, and ventilation systems, aligning with Jiangsu Province's green building guidelines. In terms of materials, the main structure often employs light steel keels or concrete prefabricated components, offering earthquake resistance, fire resistance, and thermal insulation, suitable for Nanjing's rainy and humid climate. High-strength galvanized steel or aluminum alloys are recyclable, while the walls are filled with A-grade fireproof insulation materials like rock wool and glass wool, enhancing energy efficiency and durability.

Construction Advantages and Flexibility

Construction speed is significantly faster than traditional buildings, with the main structure of small to medium-sized projects completed in just a few weeks. A standard 100-square-meter on-site prefabricated house can be installed by 2-3 workers in 1-2 days. On-site operations primarily involve bolt connections or clip fastenings, requiring low technical skills and reducing labor costs and risks. The modular design facilitates easy expansion, relocation, or disassembly of the building, with high reusability. High-quality components can be reused 5-8 times or more, significantly reducing the cost per use.

Environmental Protection, Energy Efficiency, and Industrial Foundation

Construction primarily involves dry operations, generating almost no wastewater, dust, or construction waste, meeting green construction standards. Efficient insulation layers (e.g., 75mm rock wool panels) keep indoor temperatures 5-8°C lower in summer and reduce heating energy consumption by over 30% in winter. Some factories in Nanjing have established mature production systems, such as a factory in the Jiangning Economic and Technological Development Zone with an annual production capacity exceeding 100,000 square meters, certified by ISO9001. Their products are used in projects like affordable housing and industrial parks, with on-site hoisting completed within 48 hours. Leveraging local manufacturing and research resources, this industry holds significant development potential in urban renewal, emergency shelter, and other fields.
