Prefabricated Housing Assembly in Xi'an

The development of prefabricated housing assembly-type buildings in Xi'an is excellent, with applications in multiple projects demonstrating significant advantages.

Project Application Examples

• Qinxing Jiayuan Affordable Housing Community Project: Located in the Qinhan New City of the Xixian New Area, this project employs prefabricated modular construction techniques, utilizing 36,545 prefabricated components to compress the construction period to one year, achieving an assembly rate of 63%. It marks a breakthrough in resettlement housing projects in the northwest region. The project's 'sandwich' insulated prefabricated walls are factory-integrated, with the outer concrete layer resisting wind and rain, the middle high-efficiency insulation board retaining heat and preventing cold, and the inner structural layer bearing weight and pressure. This integration of insulation, waterproofing, and structural functions eliminates the common issues of traditional exterior walls such as 'hollowing, cracking, and leakage'. After on-site hoisting, workers only need to apply the finishing layer, significantly reducing the risks of high-altitude operations and post-construction maintenance costs.
• Sany Yuncheng Project: Situated in the Fengxi New City of the Xixian New Area in Xi'an, this project adopts the SPCS prefabricated system, with each high-rise building achieving an assembly rate of no less than 50%. The total area of prefabricated construction exceeds 300,000 square meters, reaching the highest level of individual building assembly rate in Shaanxi and even the northwest region, and has been included in the first batch of prefabricated building demonstration projects in Xi'an.

Construction Characteristics

Prefabricated buildings achieve standardized design, factory-based production, and assembly-type construction through the factory production of prefabricated components such as wall panels, beams, columns, and stairs. During the production process, prefabricated components are manufactured in workshops using fully automated concrete component production lines and cured with high-temperature steam, reaching standards within 6-8 hours and enabling efficient circulation of 'production one day, assembly the next'. Each component is equipped with a unique QR code, enabling millimeter-level precise assembly through BIM technology pre-simulation and QR code traceability technology. Workers can scan the code to obtain information such as installation location and dimensional parameters.

Industry Significance

The development of prefabricated buildings in Xi'an aligns with the requirements of the national '14th Five-Year Plan' for the construction industry, serving as a key force in driving the transformation, upgrading, green development, and high-quality development of the construction industry. The development of prefabricated buildings can foster new industries, create employment opportunities, and become a new growth point for economic development, while also addressing issues such as labor shortages and rising costs in the construction industry.
