at about 10 o'clock on september 29, with the successful lifting and installation of the last steel beam, the main sail of the "jingfan" roof, the landmark building of the beijing sub-central station comprehensive transportation hub, was capped, marking the completion of the roof of this largest building in asia. the underground comprehensive transportation hub has entered the sprint stage of construction.
the urban sub-central station comprehensive transportation hub covers an area of 61 hectares, with an underground construction scale of 1.28 million square meters and an above-ground planned construction scale of approximately 1.39 million square meters. it has the characteristics of "underground hub, city above ground, and high integration of station and city". it will integrate two urban lines. it has international railways, 4 urban rail transits, 1 suburban railway, 15 bus connection lines, and reserves cruise terminal and terminal check-in functions to create a sub-center transportation center, business center and vitality center.
the unique "jingfan" roof design of the sub-central station hub has become the most eye-catching part of the project. the entire "jingfan" roof covers a total area of about 27,400 square meters, and the main sail adopts a "double-layer co-construction" structure.
since the construction of the first "jingfan" roof started on september 15, 2023, the project builders finally completed the installation and construction of the main sail steel structure of the "jingfan" roof after about 12 months of hard work. during the construction, the builders introduced advanced means such as digital model technology and three-dimensional lidar scanning reverse modeling technology to ensure that the "jingfan" roof steel structure has special-shaped structures, ceiling curves change with the steel structure, and extremely difficult construction. improve construction accuracy and efficiency.
the "beijing sail" roof means "set sail, thousands of sails compete", symbolizing the bright future of the coordinated development of the beijing-tianjin-hebei region. at the same time, a variety of green energy-saving technologies have also been incorporated, such as the use of etfe membrane materials similar to those of the national swimming center's "water cube", which not only ensures good light transmittance, heat insulation and heat preservation, but also effectively reduces the overall cost of the building. carbon emissions.
with the capping of all the "jingfan" roof main sail steel structures, the construction of the sub-central station hub has launched a sprint towards the annual construction target. it is expected that the main project will be basically completed by the end of 2024. in the future, the sub-central station hub will realize the "integration of four networks" and the "intersection of seven lines" of rail transit, becoming an important transportation node connecting the beijing-tianjin-hebei region. by then, the "jingfan" roof, as the landmark building of the sub-center station hub, will become the new landmark building of the sub-center and an important part of the city's green axis, providing citizens with colorful activity venues and green and ecological leisure spaces.
