Chengdu Prefabricated Frame Structure House
Chengdu prefabricated frame structure houses exhibit significant characteristics in terms of technological innovation, application promotion, and cost.
In terms of technological innovation, Chengdu's prefabricated integrated houses mostly adopt a combination of steel structures and lightweight composite walls, belonging to the fields of building industrialization and green building materials. Building components are standardized and produced in factories and then transported to the site for rapid assembly, improving construction efficiency and quality controllability. The new fully assembled steel-concrete frame structure system developed by China MCC5 Group is particularly outstanding. This system employs reinforced concrete modular structures and high-strength bolt connection technology, with the main structure entirely assembled from factory-prefabricated components. It can achieve an earthquake resistance level of 8, offers better thermal insulation and energy efficiency for the house, and reduces on-site wet operations through factory production, thereby minimizing the environmental impact of construction.
Regarding application promotion, the new fully assembled steel-concrete frame structure system has been successfully promoted in new rural construction projects around Chengdu. The construction speed of this system has significantly increased, enabling the completion of foundation and main structure in 6 days and delivery in 30 days, saving 4-5 months compared to the construction period of traditional rural houses. This rapid construction model not only shortens the construction cycle but also reduces labor and time costs, making it particularly suitable for centralized construction needs in rural areas and providing an efficient and safe building solution for rural revitalization.
In terms of cost composition, the civil engineering cost (including foundation, walls, floor slabs, and other structural components) of frame structure houses in Chengdu ranges from 1,100 to 1,300 yuan per square meter. This quotation does not include expenses for land acquisition, house decoration, and landscaping, and the specific cost is influenced by material prices, labor costs, and construction difficulty. For example, fluctuations in the prices of steel and concrete directly affect the total cost, while increased complexity of construction terrain or higher design requirements may increase machinery and labor costs. Although the initial cost of China MCC5 Group's new system may be slightly higher, it offers long-term economic advantages by shortening the construction period and reducing on-site management expenses, making it particularly cost-effective for large-scale promotion.
In summary, Chengdu's prefabricated frame structure houses have achieved efficient, safe, and green construction goals through technological innovation. Their application promotion and cost optimization provide a typical example for building industrialization.
