Nanyang Concrete House Prefabrication

Nanyang concrete house prefabrication mainly takes the form of prefabricated cement integrated houses, featuring rapid construction, low cost, and strong earthquake and wind resistance, but with average sound insulation and classified as temporary buildings.

Construction Method and Efficiency: The prefabricated concrete houses in Nanyang are constructed using factory-prefabricated modules assembled on-site. Reinforced concrete modules are pre-made in the factory, transported to the construction site, and directly assembled using lifting equipment. The main structure can be completed in 1 to 3 days, significantly shortening the construction period and making it suitable for projects with tight deadlines.

Cost and Economy: For a 120-square-meter house, the main construction cost is approximately 120,000 to 150,000 yuan, 30% lower than that of traditional buildings. If used for short-term rentals, the annual rent for a single room can reach 5,000 yuan, resulting in a relatively short investment return period. Additionally, the modules can be repeatedly disassembled and reused, further reducing long-term usage costs.

Suppliers and Coverage: Local suppliers in Nanyang, represented by Yuanfa Building Materials, provide standard-sized prefabricated modules in the vocational education park, with a service range extending up to 150 kilometers, meeting the needs of surrounding areas. Another supplier, Nanyang Prefabricated Component Factory, located in Bianzhuang Village, Qiliyuan Township, Wolong District, specializes in producing concrete drainage pipes, bridge slabs, and other components, serving urban construction and major projects.

Installation and Foundation Requirements: On-site installation requires a 50-ton crane and 3 workers. The foundation must be constructed in advance according to design requirements to ensure the stability and safety of module assembly. The installation process has low technical requirements but must strictly follow operational specifications.

Advantages and Disadvantages Analysis:

• Advantages:
  • Outstanding Earthquake and Wind Resistance: Capable of withstanding magnitude 8 earthquakes and typhoons of force 12, suitable for areas prone to geological disasters or strong winds.
  • Significant Cost-Effectiveness: Low material and labor costs, suitable for scenarios such as homestays, warehouses, and temporary housing.
• Disadvantages:
  • Average Sound Insulation: Gaps may exist at module joints, requiring additional soundproofing materials for improvement.
  • Property Rights Restrictions: Classified as temporary buildings, unable to obtain property certificates, requiring consideration of policy risks for long-term use.

Suitable Scenarios: Prefabricated houses are suitable for cost-sensitive and time-constrained projects, such as rural self-built houses, tourist homestays, and emergency shelters. For long-term residence or commercial development, comprehensive evaluation based on local planning policies is necessary.
