Xiangtan Concrete Prefabricated Houses
Xiangtan has witnessed rapid development in the field of concrete prefabricated houses (prefabricated buildings), forming a well-established industrial ecosystem with policy support, technological innovation, widespread application, and comprehensive service models.
Prominent Policy Support and Industry Status
Xiangtan City has a clear policy orientation in the prefabricated building sector. The "Three-Year Action Plan for the Development and Enhancement of Green Construction in Prefabricated Buildings in Xiangtan City," released in August 2022, explicitly outlines directions for industrialization, greening, and intelligence, promoting the integration of green building materials and construction industry chains. As of relevant reports, Xiangtan ranks among the top three in Hunan Province in terms of the proportion of prefabricated buildings in newly constructed building areas, becoming a benchmark city for prefabricated building development in Hunan. Policy support is not only reflected at the planning level but also strengthens industrial agglomeration effects through industrial chain layout, laying a foundation for technological implementation and market promotion.
Significant Technological Innovation Achievements by Enterprises
Local enterprises, in collaboration with research institutions, have developed multiple core technologies. For example, Hunan Hengyun Construction Technology and Xiangtan Architectural Design Institute jointly developed the "UHPC-connected low-rise to multi-story fully prefabricated concrete wall panel structural system." This system achieves efficient connections through a combination of "fully prefabricated wall panels + fully prefabricated floor slabs," combined with cast-in-place edge members and UHPC grout anchor connection boxes. The system combines safety, economy, and environmental friendliness, with a main structural lifespan exceeding 70 years, suitable for low-rise to multi-story residential buildings and dormitory scenarios. Such innovative achievements have driven the upgrade of prefabricated buildings from single structures to systematic solutions.
Diversified Expansion of Application Scenarios
Prefabricated buildings in Xiangtan have covered multiple fields such as residential housing and villas. For instance, a 140-square-meter heavy steel villa constructed using prefabricated technology in Baihe Village, Zhaoshan Town, Yuetang District, Xiangtan City, is fully functional and meets family needs. The non-removable formwork cast-in-place villa achieves integrated forming of load-bearing, thermal insulation, and sound insulation through on-site assembly of factory-prefabricated steel mesh components, reducing the construction period by nearly half compared to traditional brick-and-mortar structures and significantly improving earthquake resistance, particularly suited to Hunan's climate conditions of rainy and humid weather, cold winters, and hot summers.
Full-Chain Integration of Service Models
Some enterprises, such as Hunan Ziyoujia Construction and Decoration Engineering Co., Ltd., have established an integrated service system from production to delivery. Relying on the Xiangtan Economic and Technological Development Zone Prefabricated Building and Decoration Industrial Park, the enterprise possesses modern workshops, talent incubation bases, and whole-house decoration experience centers, offering one-stop services for "house construction + interior decoration." This model simplifies the responsible entities, strengthens after-sales support, reduces user coordination costs, and promotes the in-depth penetration of prefabricated buildings into the consumer end.
