Service Stage: Scheme + Preliminary Design + Construction Drawing
The project is located in the South Square of the South Railway Station. The design idea of the project absorbs the continuous stream of vehicle lines in the high-speed railway network, extracts rail elements, and uses dynamic and powerful architectural language to create the real touch of landmark buildings in the high-speed railway area.
As a large-scale complex project of urban portal space, the technical difficulties in the design process focus on two aspects: how to break the conventional shape of the super-high-rise office tower, how to create a distinctive urban space and how to achieve the integrity of commercial volume under the current condition of urban road segmentation.
The design changes the standard floor of the office tower in different layers, and forms the external space of different layers by the way of exterior curtain wall pulling out and retreating, so as to form the super-high-rise tower model with sense of rise and change.Aiming at the second problem, the difficulty lies in how to solve the problem of building's nearly 40-metre span from the structural point of view. In the design, the internal function is fully combined with the structural design, and the atrium space is arranged in the overhead part, so as to reduce the local load and the difficulty of the structural part. At the same time, a variety of structural solutions including steel structure, well-shaped beam structure and prestressing beam are considered comprehensively. To a large extent, the influence of structural space on internal use space is weakened.
