Prefabricated Houses in Zhongshan
Zhongshan has multiple practical application cases and policy support in the field of prefabricated houses (prefabricated buildings), demonstrating active practice and development trends.
I. Practical Application Cases
Zhongshan Vanke Central Park Project Located on Zhengxian Street in Guzhen Town, Zhongshan City, this project is a typical application of prefabricated buildings in high-rise residential structures. Fourteen high-rise residential towers, starting from the second floor upwards, employ prefabricated technology, primarily using four types of prefabricated components: prefabricated concrete floor slabs (including roof slabs and balcony slabs), formwork-free templates, ceramsite concrete hollow slabs, and prefabricated stairs. The assembly rate reaches 50.2%, meeting the basic-level requirements of Guangdong Province's "Prefabricated Building Evaluation Standards." By assembling standardized prefabricated components on-site, the project significantly shortens the construction period while reducing on-site wet operations and construction waste, showcasing the advantages of prefabricated buildings in terms of efficiency and environmental protection.
Lan Shang Talent Apartment Project As the first affordable rental housing project in Zhongshan City to pass the prefabricated building pre-evaluation, Lan Shang Talent Apartment is located in Jidongyi, Xiaolan Town, with a total construction area of 20,216.94 square meters. Among them, residential buildings 1 and 2 are constructed using prefabricated methods, with a prefabricated construction area of 13,725.09 square meters. The project selects prefabricated components such as non-removable formwork and ALC slabs (autoclaved aerated concrete slabs), with an assembly rate exceeding 50%, meeting the basic-level standards. ALC slabs possess characteristics such as lightweight, high strength, sound insulation, and thermal insulation, while non-removable formwork simplifies the construction process. The combination of these two enhances the construction quality and living comfort of affordable housing.
II. Policy Support The Zhongshan Housing and Urban-Rural Development Bureau promotes the development of the entire industrial chain by organizing the application and evaluation of prefabricated building industrial bases and demonstration projects for the year 2024. The policy encourages enterprises to apply for industrial bases in production (such as prefabricated component manufacturing), equipment manufacturing (such as intelligent construction equipment), education and training (such as technical worker training), and development and construction (such as prefabricated project development), forming a complete industrial ecosystem covering design, production, construction, and operation and maintenance. This initiative aims to enhance the technological level and market competitiveness of prefabricated buildings and promote the transformation of the construction industry towards industrialization.
III. Development Significance The practice in Zhongshan demonstrates that prefabricated buildings effectively improve construction quality and efficiency while reducing resource consumption and environmental pollution through standardized design, factory-based production, and assembly-based construction. The dual drive of policies and projects provides replicable experience for the promotion of prefabricated buildings in areas such as affordable housing and commercial residential buildings, assisting Zhongshan in moving towards a green, low-carbon, and intelligent construction industry direction.
