Vanke Prefabricated House Framework

Vanke has significant technological accumulation and application advantages in the field of prefabricated house frameworks.

I. Technological Accumulation and Patent Achievements
Since 2003, Vanke has been promoting prefabricated construction and established the Vanke Industrialization Center, focusing on research into prefabricated assembly systems. To date, it has accumulated 6 invention patents and 8 utility model patents, achieving localization of key technological products. These patent achievements provide core technological support for the design, production, and construction of prefabricated house frameworks, forming independent intellectual property rights in areas such as connection nodes and componentized structural elements, enhancing technological barriers and industry competitiveness.

II. Technological Model and Applicable Scenarios
Vanke primarily employs a reinforced concrete prefabricated assembly construction model, suitable for multi-story and low-rise office and residential buildings. Its technological system, based on traditional frame and frame-shear structures, emphasizes the componentization of exterior wall panels, interior wall panels, and floor slabs, with a componentization rate of 40% to 50%. Through standardized design, factory-based production, and assembly construction, it achieves the integration of building industrialization and on-site decoration, effectively reducing costs. Currently, costs are close to those of traditional techniques, while construction efficiency has significantly improved, enabling the construction of approximately one floor every five days.

III. Typical Projects and Technological Innovations

1. Nanjing Jindi Yufang Project: This project adopts a prestressed prefabricated concrete assembled integral frame structure system, reflecting Vanke's technological exploration in prefabricated frame structures. Through prestressing technology, it enhances the overall structural integrity and seismic performance.
2. Vanke Jiuduhui Project: This project utilizes the Sujiejia system as a new support framework, replacing traditional steel tube scaffolding. The Sujiejia system addresses issues such as slow setup speed, high density, low safety performance, and insufficient support precision in traditional support systems, meeting the requirements for efficient, safe, and precise construction in prefabricated assembly buildings while adhering to green and environmentally friendly principles.

IV. Technological Advantages and Industry Impact
Vanke's technological system reduces on-site wet operations and construction waste through componentization, standardization, and industrialized production, improving construction quality and efficiency. Although its costs are close to those of traditional techniques, construction periods are significantly shortened, and safety risks are further reduced through innovations in support systems. These advantages have established Vanke as an industry benchmark in the field of prefabricated house frameworks, driving the popularization and application of prefabricated construction in China.
