The area of the metallic building roof steel structure of the corridor is about 14,000 square meters, the weight is about 1200t, and the lifting height is 10m. The total weight of the steel structure of the corridor roof is about 5,000t, and the total projected area of the roof is 56,000 m². It is a welded ball space frame structure with variable grid shapes, a large number of components, complicated specifications, and great disparity in assembly height, making construction difficult.
Up to now, the main body of the roof steel structure space frame of the four corridors of the project has been basically completed, and the airport terminal shows a beautiful design curve of the roof. The T3B terminal building has a construction area of 368,000 square meters and a maximum building height of about 37.7 meters.
The building appearance of the T3B airport building adopts an X shape, consisting of the main building and four corridors, which are consistent with T3A in terms of style and flow. This expansion is the last large-scale expansion of Jiangbei Airport, and the T3B terminal building is the “largest single satellite hall” that has attracted worldwide attention. After the completion of the project, Jiangbei International Airport will form a layout of 4 runways and 4 terminals to meet the annual passenger throughput of 80 million passengers, 580,000 aircraft takeoffs and landings, and 1.2 million tons of cargo and mail throughput. promote.
