Zhangjiajie Rural Prefabricated Houses
Rural prefabricated houses in Zhangjiajie mainly include two forms: movable panel houses and steel-structure villas.
Movable Panel Houses Movable panel houses are constructed with a lightweight steel structure as the framework and sandwich panels as the enclosure materials, assembled through standard modular space combinations and bolt connections. Their core advantage lies in their "movability," allowing for rapid assembly, disassembly, and reuse, making them particularly suitable for the complex terrain of Zhangjiajie's mountainous areas. Convenience is demonstrated in three aspects: First, standardized design ensures strong component versatility, facilitating mass production; second, modular structures support rapid transportation, adapting to mountainous traffic conditions; third, a simple installation process shortens construction periods and reduces reliance on terrain. In terms of practicality, movable panel houses can meet diverse needs: In basic residential scenarios, reasonable layouts enable functional zoning for daily life; in office and commercial settings, space functionality can be transformed by adding partitions or modifying doors and windows; in storage scenarios, their moisture-proof and fire-resistant properties safeguard equipment and supplies.
Steel-Structure Villas Steel-structure villas represent an integrated building system encompassing the entire process from design, manufacturing, construction, to decoration. Their performance is determined by three core parameters: Steel Usage directly affects structural strength, with high-quality projects using scientifically calculated amounts of steel to ensure safety margins; Structural Form employs a frame-shear wall system, enhancing seismic performance through rational load paths; Connection Technology utilizes high-strength bolts or welding techniques to ensure node reliability. Corrosion-treated steel structures are designed for a service life exceeding 70 years, with a general seismic fortification intensity of 8 degrees, achieving thermal insulation through the filling of Class A fire-resistant rock wool. Advantages are manifested in four areas: First, efficiency and speed, with factory-prefabricated components assembled on-site, reducing construction periods by over 50% compared to traditional buildings; second, safety and durability, as steel's good ductility absorbs seismic energy, while corrosion-resistant treatments extend service life; third, green environmental protection, with over 90% of components being recyclable and significantly reduced construction dust and noise pollution; fourth, flexibility and adaptability, allowing adjustments to partition layouts or floor heights to suit different functional requirements. In rural Zhangjiajie, steel-structure villas are suitable for newly built self-occupied villas, rural tourism homestays, mountainous and sloped land constructions, and renovations of old houses.
