Installation of Prefabricated Panel Assembled Houses

The core process of installing prefabricated panel assembled houses is similar to 'building blocks', enabling rapid assembly through standardized components and offering characteristics such as efficiency, environmental friendliness, and cost-effectiveness. Details are as follows:

1. Component Production and Connection Methods

Prefabricated components are primarily panel-based structures made of reinforced concrete materials. They are manufactured through precise factory calculations and mold forming to ensure standardized dimensions and structural stability. Components are mainly connected using mechanical bolts. For example, in the Ningbo Jiangbei case, rapid assembly is achieved through bolt fixation, reducing on-site wet work. Traditional prefabricated panels come in two types: solid and hollow. The hollow structure achieves lightweighting by reducing non-load-bearing concrete, but cast-in-place concrete and prefabricated buildings have gradually replaced traditional prefabricated panel houses.

2. Installation Speed and Cost-Effectiveness

The construction efficiency of prefabricated panel assembled houses is significantly higher than that of traditional buildings:

• The Henan case shows that a house can be assembled within 4 hours, with a cost of approximately 300 yuan per square meter and a service life of up to 70 years;
• In the Ningbo case, a fully prefabricated rural house can complete its main structure within 7 days;
• Modular buildings achieve a 50%-70% increase in construction speed compared to traditional methods through the combination of prefabricated functional units.
  Additionally, prefabricated assembled buildings can shorten construction periods, reduce pollution, and have reusable components, further lowering overall costs.

3. Technical Types and Structural Advantages

Prefabricated assembled buildings encompass various technical types:

• Panel-based assembly: Primarily using panel-based components, suitable for low-rise residential buildings;
• Box-based assembly: Combining complete functional modules, suitable for rapid deployment;
• Frame-based assembly: Supported by steel or concrete frames, capable of construction up to 5 stories.
  For example, CMC combined modular buildings adopt steel-concrete integrated pouring technology, offering superior seismic performance compared to traditional structures and reducing construction periods by 30%.

4. Application Scenarios and Policy Support

Prefabricated panel assembled houses are widely used in residential, dormitory, office building, and other scenarios, with a maximum height of 5 stories. Since 2022, China has implemented renovation policies, focusing on repairing and renovating prefabricated houses while only demolishing those that meet hazardous building standards. Regions like Fujian have established industrial bases through policy support, reducing construction waste by over 70% and achieving green construction.

5. Market Development and Export Potential

Chinese prefabricated houses have demonstrated strong performance in the international market. In the first four months of 2026, the Guangzhou Customs District exported movable houses worth 1.4 billion yuan, a year-on-year increase of 38.1%. These houses are primarily sold for overseas emergency housing and temporary office use, showcasing technological maturity and cost competitiveness.
