Feixi Cement Prefabricated Housing

Feixi County has relevant practices and industrial foundations in the field of cement prefabricated housing, but selection for application should be based on specific needs and conditions.

I. Practical Cases and Technical Features Feixi County has implemented multiple modular construction projects, such as the expansion of the Huainan City Branch of Hefei No.42 Middle School and the expansion of Feicui Lake Junior High School, utilizing the core construction technology of prefabricated 4.0. Its core features include:

1. Factory Prefabrication and On-site Assembly: Using rooms as modular units, non-load-bearing walls, floor slabs, and other components are prefabricated in the factory. On-site, they are quickly assembled using reliable connection technologies, with a single-unit assembly rate of no less than 80%.
2. Efficiency and Environmental Advantages: Compared to traditional construction, the project duration can be shortened by nearly 50%. Additionally, it reduces on-site wet operations, lowering dust and noise pollution, and meets the requirements of green and low-carbon construction.
3. Technical Standards: The project passes technical solution reviews during the design phase to ensure structural safety and functional integrity, making it suitable for public building scenarios such as education and offices.

II. Industrial Foundations and Product Types There are cement prefabricated component manufacturers in Feixi County, such as Hefei Feixi PC Component Manufacturers, which mainly produce:

1. Non-load-bearing Components: Prefabricated non-load-bearing walls and ALC insulation panels (which combine insulation and lightweight properties), suitable for building envelopes.
2. Municipal Components: Prefabricated components for utility tunnels, used in the construction of underground utility corridors, improving construction efficiency and durability.
3. Service Scope: Covering Feixi County and its surrounding areas, providing localized supply chain support for modular construction.

III. Application Limitations and Considerations

1. Seismic Performance: The seismic capacity of modular housing depends on the design of connection nodes. In non-seismic zones (such as the area where Feixi County is located), it can meet regular needs, but the construction of high-rise modular buildings in strong earthquake zones or high-intensity fortification areas should be avoided.
2. Floor Limitations: Due to the impact of connection stability and overall rigidity, modular buildings should not be too high in floor count, typically suitable for low to multi-story buildings (such as 3-6 stories).
3. Design Adaptability: Module sizes and connection methods need to be customized according to building functions and site conditions to avoid conflicts between standardized components and personalized needs.

IV. Summary Feixi County has verified the technical feasibility of cement prefabricated housing through practical projects and has formed a certain level of industrial support capacity. Its advantages lie in shortening construction periods and being environmentally friendly and energy-efficient. However, it is necessary to strictly control the design of connection nodes, limit building heights, and select appropriate scenarios based on regional geological conditions. For public buildings, temporary facilities, or low to multi-story residential buildings, modular prefabricated housing is an efficient choice; for high-rise buildings or buildings in earthquake-prone areas, traditional construction methods or enhanced modular technologies are still required.
