The application scenarios of membrane structure are very wide. Today, I will introduce to you the T2 Terminal of Changbei International Airport in Nanchang, Jiangxi Province. The construction project of the roof of the main building also uses ETFE air pillow membrane materials to form a transparent “sky curtain”, which improves the beauty and transparency of the building.

The ETFE air pillow membrane scheme for the roof of the main building of the terminal refers to a roof structure scheme for the main building of the terminal based on ETFE air pillow membrane materials. ETFE air pillow membrane is a transparent, lightweight membrane material with high light transmittance and weather resistance, which is widely used in the fields of construction and aerospace. In the ETFE air pillow membrane scheme for the roof of the main building of the terminal, a large area of ​​ETFE air pillow membrane is used to cover the entire roof of the main building, forming a transparent “sky curtain”, which makes the whole building feel light and transparent. The scheme also adopts the design of multi-layer ETFE air pillow membrane, with air filled in the middle to form an air pillow insulation layer, which improves the thermal insulation performance of the building. In addition, the scheme also uses advanced structural technology and materials to ensure the stability and safety of the roof structure.

The project has a construction area of ​​about 22,200 square meters and a building height of 34.6 meters. The designer adopted a “cloud-like” architectural form to integrate the building with the sky, giving the building a rich sense of space and visual effects. In terms of structural design, the main building roof adopts a precast concrete frame and hollow steel pipe support structure, which has good stability and seismic performance. The project uses advanced building materials and technologies to improve the comfort and environmental performance of the building, in line with the concept of sustainable development.

The roof of the main building of Terminal 2 of Changbei International Airport uses ETFE material as the main building material. ETFE is a high-performance transparent fluoropolymer material with the characteristics of high transparency, light weight, and strong weather resistance.
