Prefabricated Housing Construction in Xiongan New Area
Xiongan New Area has conducted extensive practices and innovations in the field of prefabricated housing construction, forming notable characteristics such as the widespread adoption of prefabricated construction methods, a diversified technical system, full-process digital management, coordinated development of the industrial chain, outstanding green and safety performance, and standardization and quality control.
Widespread Adoption of Prefabricated Construction Methods: 80% to 90% of buildings in Xiongan New Area utilize prefabricated technology, with factory-produced walls, floor slabs, stairs, and other components transported to the construction site for assembly, achieving 'building houses like making cars'. For example, the Xiongan Sports Center project adopted steel-structured prefabricated construction, and the Citizen Service Center project completed the封顶 (topping-out) of its main structure in just 1,000 hours, significantly shortening the construction period.
Diversified Technical System: It covers cold-formed thin-walled light steel, modern light wood structures, heavy-light steel hybrid, and enclosure wall product systems, offering advantages such as fast construction speed, minimal climate constraints, and resource and energy conservation. The production of prefabricated components employs automated assembly lines, with CNC technology used to machine steel molds and computer monitoring systems to control curing temperatures and humidity, ensuring component precision and durability.
Full-Process Digital Management: BIM (Building Information Modeling) technology is used to simulate the entire construction process, identifying and resolving issues in advance; each component is labeled with a QR code 'ID card' containing basic information and installation location, allowing workers to scan and obtain installation guidance for precise scheduling.
Outstanding Green and Safety Performance: The prefabricated building system has a lifespan exceeding 70 years, with a seismic resistance rating above 9, and building materials that are fire-resistant, moisture-proof, and insect-proof, aligning with Xiongan New Area's positioning as a 'green, ecological, and livable new city'. For example, practices in earthquake-prone regions of Japan have verified its seismic resistance and durability.
Standardization and Quality Control: Strict standards are established throughout the production process, from raw material inspection, concrete mix design, to component load testing, with technical parameters recorded throughout to form traceable archives, ensuring building quality.
