Anhui Prefabricated House Construction
Anhui prefabricated house construction covers multiple aspects including construction plans, component production and transportation, on-site installation, quality control, technological innovation, and policy support.
Construction Plans and Processes: Anhui prefabricated house construction adopts standardized plans, clarifies project management structures, divides construction areas, and controls key nodes. Taking the project in Shushan District, Hefei City as an example, a project management department is established, equipped with professional teams for technology, construction, quality and safety, etc. The project is divided into multiple construction sections, and the “flow within sections and parallel between sections” operation method is adopted to improve construction efficiency.
Production and Transportation of Prefabricated Components: Components are precisely produced in factories, covering prefabricated exterior wall panels, composite floor slabs, prefabricated stairs, etc. Custom molds and integral reinforced steel bar frameworks are used to ensure precision and quality. During transportation, special transportation racks are used, with support points set at 1/4 of the component's span and vehicle speeds controlled within 60 km/h to ensure the safe arrival of components at the construction site.
On-site Construction and Installation: Before construction, site hardening, setting up of component stacking areas, and temporary water and electricity arrangements are required. After the components arrive, they are quickly assembled using full-bolt connections without wet operations, reducing construction waste and dust pollution. For example, Anhui Construction Engineering's prefabricated steel structure building system only takes 15 days for the assembly of the main structure and 30 days for occupancy.
Quality Control and Supervision: Full-process quality monitoring is implemented, covering key nodes such as component factory acceptance, first-piece installation, and main structure capping. In Mengcheng County's “Wanmei Hao Nongfang” project, an innovative “Five Goods and One Strict” work system has been introduced, namely good standards, good designs, good materials, good construction, good costs, and strict supervision, systematically reshaping the entire process of rural house construction.
Technological Innovation and Intelligent Applications: Enterprises actively apply intelligent means such as BIM technology and digital management to improve construction efficiency and precision. For example, collision detection, construction simulation, and component information embedding are carried out through BIM. The prefabricated steel structure building system adopts fully prefabricated construction, with component installation errors controlled within millimeters, achieving full-cycle protection for seismic resistance and intelligent operation and maintenance.
Policy Support and Market Development: Anhui responds to the national development strategies of green buildings and prefabricated buildings by introducing a series of policies and regulations to boost the development of prefabricated buildings. In 2024, the construction area of prefabricated buildings in the province reached 54.26 million square meters, accounting for 47.2% of newly built buildings, showing strong market development momentum.
