Prefabricated House Walls in Xiongan New Area
The prefabricated house walls in Xiongan New Area adopt a prefabricated construction method, combining factory prefabrication with on-site assembly, and incorporating technological innovations and quality improvement measures.
I. Factory Prefabrication Process
The production of prefabricated house walls begins with precise detailed design, determining wall dimensions, embedded part locations, and connection node details based on architectural structural drawings to ensure compatibility between components and the overall structure. Subsequently, concrete pouring and vibration are completed on fixed formwork tables or automated assembly lines, ensuring wall density and flatness through standardized processes. After pouring, components enter the steam curing phase, utilizing high-temperature and high-humidity environments to accelerate concrete strength development, shorten the curing cycle, and enhance early strength. Finally, after passing quality inspections, components are labeled with QR code 'identification cards' that record information such as specifications, production dates, and installation locations, providing precise data support for subsequent construction.
II. On-Site Assembly and Connection Reinforcement
After being transported to the construction site, prefabricated walls require reinforcement of connection nodes through reinforced concrete overlapping and pouring. Specifically, the reserved reinforcing bars of adjacent components are bound or welded together to form an integral unit, and high-strength concrete is poured to fill the gaps, creating a rigid connection between the walls and the structural framework. This process significantly enhances the overall integrity and seismic resistance of the building while reducing on-site wet work and shortening the construction period. During installation, workers scan the component QR codes to obtain installation information, enabling precise positioning and efficient scheduling and avoiding rework caused by human errors.
III. Technological Innovation and Quality Improvement
Under the 'high-quality housing' standards in Xiongan New Area, higher requirements are placed on wall performance. For example, partition walls are upgraded to heavy solid brick walls, replacing traditional aerated concrete blocks, effectively blocking sound transmission and reducing noise interference between households by increasing wall density. Additionally, the production of prefabricated components employs automated assembly lines and intelligent monitoring systems to control parameters such as concrete mix ratios and vibration times in real-time, ensuring component quality stability. The application of QR code technology enables full lifecycle traceability management, allowing monitoring from production to installation through a data platform and providing a basis for later maintenance.
The prefabricated house wall construction model in Xiongan New Area, through industrialized production, refined connections, and intelligent management as its three core strategies, balances efficiency and quality, providing replicable practical experience for the development of prefabricated buildings.
