Sichuan Prefabricated Houses

Sichuan prefabricated houses, with their core advantages of efficient construction, strong earthquake resistance, environmental protection, and customization, are widely applied in rural housing, post-disaster reconstruction, and cultural tourism projects, becoming an important direction for the upgrading of the construction industry.

Diverse Types and Structures
Sichuan prefabricated houses cover three mainstream types:

1. Prefabricated Light Steel Structures: Taking Mianyang Yuhuang Community as an example, it adopts a light steel keel frame, which is lightweight and highly ductile, with significantly better earthquake resistance than traditional brick-concrete structures. The cost of constructing a 180㎡ house is approximately 300,000 yuan, with a construction period of only 40 days, 50% shorter than traditional methods.
2. Reinforced Concrete Prefabricated Structures: Such as Fubainian cement houses, which are cast as a whole with reinforced concrete throughout the house. The cost of the main structure of a 200㎡ house is 110,000 yuan, emphasizing durability with the concept of 'one house for three generations'. Weighing up to 100 tons, they resist earthquake risks through structural stability.
3. Modular Integrated Design: Using light steel or concrete prefabricated components as the main body, integrating wall, floor, and roof systems, it supports flexible combinations from single-story rural residences to multi-story public buildings, meeting diverse needs such as cultural tourism projects.

Prominent Core Advantages

1. Efficient Construction and Quality Assurance: Factory-standardized production of components allows for rapid on-site assembly, reducing wet work and shortening the construction period by more than 50%. BIM technology enables collaborative design, and automated production lines ensure component precision, with products passing national building standard certifications.
2. Earthquake Resistance and Geographical Adaptability: Aimed at the earthquake-prone environment in Sichuan, light steel houses enhance earthquake resistance through ductile design, while concrete houses rely on their weight and structural stability to cope with risks. Both types of houses have been verified for safety through actual cases.
3. Environmental Protection and Customized Services: Factory production reduces construction errors and construction waste. Multiple standardized house types are provided, supporting space customization such as high ceilings in living rooms. Yuhuang Community decides on house types through villager votes, enhancing acceptance.

Wide Range of Application Scenarios

1. Rural Housing: Mianyang has incorporated prefabricated rural houses into its development system, with 29 light steel structure houses in Yuhuang Community selected as typical cases in Sichuan Province.
2. Post-Disaster Reconstruction and Temporary Facilities: The rapid assembly characteristics of prefabricated houses make them the preferred solution for emergency shelter and temporary buildings after earthquakes.
3. Cultural Tourism Projects: Modular design supports flexible layouts, suitable for scenarios such as homestays and visitor centers.

Policy and Industry Synergy
Sichuan Province has formulated design guidelines and general drawings, piloting the factory prefabrication and on-site assembly model. The localization of factory layouts shortens the supply chain, with a factory in Chengdu having an annual production capacity covering complex geological projects in the western Sichuan Plateau and Panxi region, promoting the level of regional construction industrialization.
