Prefabricated House Construction in Changzhi

Changzhi has made remarkable progress in the field of prefabricated housing, with the Shanxi Construction Industry Modernization Changzhi Park Project as a representative example, forming a complete industrial chain and advanced technological system.

I. Project Positioning and Industrial Model
The Shanxi Construction Industry Modernization Changzhi Park Project, located in the Huguan Economic Development Zone, is a provincial-level key project that adopts an industrial model of 'factory-made modules for faster house construction'. This model breaks down the traditional construction process into two stages: factory-based production and on-site assembly. Building components are manufactured on production lines in the base and then quickly assembled on-site in a 'building block' manner. This approach overcomes the limitations of traditional construction methods, which are affected by weather and site conditions, significantly shortening the construction period. For example, buildings like the technology research and development building can achieve a construction speed of completing one floor in six days.

II. Core Production Capabilities and Technological Support
Plant No. 2 in the park covers an area of over 50,000 square meters and is equipped with an internationally advanced information management system that covers the entire process, including architectural design, steel structure drawing optimization, process design, and VR/3D visualization technology. Its technical team, composed of highly skilled professionals, enables digital closed-loop management from design to production. During the production process, intelligent steel structure H-beam automatic production lines, box-section steel and non-standard steel structure automatic production lines work in tandem, complemented by high-precision laser cutting machines, CNC five-axis plasma bevel cutting machines, and other equipment. These enable precise processing of complex components to meet diverse customer needs. By directly importing design data into CNC equipment, various irregular parts can be efficiently produced with millimeter-level accuracy.

III. Advantages of Prefabricated Construction
The park prefabricates building components such as beams, slabs, columns, and walls in the factory and then transports them to the site for modular assembly. This construction method reduces on-site wet work, lowering dust and noise pollution, while improving building quality stability through standardized component production. For example, the factory-based production of steel structure components avoids the deformation risks associated with on-site welding, and the assembly process uses bolt connections or welding techniques to ensure structural safety. Additionally, modular design supports flexible adjustments to building functions, facilitating future renovations and upgrades.

IV. Industrial Demonstration Effect
As a benchmark in Changzhi's prefabricated housing sector, this project has driven regional architectural industry upgrades. Its integrated 'design-production-construction' model provides a replicable industrial construction template for the industry, spurring the development of related local industrial chains such as steel structure processing and logistics transportation. It has helped Changzhi establish a competitive edge in green building and intelligent construction fields.
