Yexing tensile membrane structure
The permanent venue project of the International Finance Forum (IFF) is located at the tip of Hengli Island, Mingzhu Bay, Nansha New Area, Guangzhou City. The project covers an area of approximately 200,000 square meters and has a total construction scale of about 238,000 square meters. Its main functions include an international conference center, a service hotel and a residence for political dignitaries.
The design concept of the plan is “Kapok flowers in full bloom, Soaring along the Maritime Silk Road”. The main building of the IFF permanent venue adopts modern techniques to represent the culture of Lingnan, forming an abstract “kapok flower” architectural form. This is not a deliberately designed flower-shaped building with an elegant and dynamic design. From a distance, it looks just like a blooming kapok flower in the wind, representing the unique regional culture of Guangzhou and Nansha. Each petal is different, yet they are of one heart, embodying the beauty of the city of flowers and symbolizing the convergence of hearts in the bay area and the blooming of prosperity and good fortune.
In addition to the iconic cultural symbol “Kapok Flower”, the building’s facade facing the river is shaped like a wild goose about to take flight, like a messenger connecting distant places. As the permanent venue of IFF, it connects China with the world like the Maritime Silk Road, featuring “a global perspective, Chinese style and Lingnan characteristics”.
The project achieves precise spatial positioning of steel structures and curtain walls through international cutting-edge new technologies such as full-process digital visual design and dynamic structural monitoring. The tiny digital model carries over 14,000 tons of steel, more than 40,000 square meters of metal curtain wall materials, as well as approximately 7,000 square meters of UHPC and nearly 20,000 square meters of PTFE membranes and other new building materials.
This project innovatively adopted the first 3.9-meter-wide suspended perforated PTFE mesh membrane curtain wall in China, which was completed with great efforts by Yexing Membrane Structure. Its tensile strength is equivalent to that of steel of the same specification, but its weight is only 65% of that of steel, with a light transmittance as high as 60%. It features high optical performance, excellent ductility, stable chemical properties, outstanding self-cleaning ability, UV resistance, and chemical corrosion resistance, which can make the “kapok flower” present a one-piece formed visual effect.
The east facade of the building forms a double-layer curtain wall of the Lingnan “arcade” through PTFE membrane and the inner glass curtain wall. While meeting the requirements of shading and rain protection, the transparent PTFE membrane also takes into account the needs of energy conservation and indoor viewing, hanging down like a light gauze curtain and naturally connecting with the arched canopy, creating an elevated entrance gray space.
The design of the permanent venue project for the Nansha International Finance Forum takes adapting to the characteristics of the site as the entry point, draws on traditional imagery, is based on the local cultural context, and combines modern innovative technologies to meet the needs of an international high-end conference center, with the aim of becoming a landmark building at the tip of Hengli Island. The permanent Nansha International Finance Forum will also help Nansha go global.
