Eggshell shaped and hyperboloid grid frame structure roof is designed for Xinzheng International Airport terminal T2 with large span and space reversible cornice planed ceiling indoors in the main building area. It can flip over along the roof, taking self?diagonal as the axis to meet the requirement of the indoor natural lighting. In addition, with the green energy?saving, environmental protecting and novel form, it is the first domestic innovation in China. This large?area surface modeling of ceiling system is complex and difficult to build. The rotating unit has 28 kinds of angle from 7°~38°. Through optimization of the designs,3D modeling, strict measurement and calculation, using bolting connection technology and professional customization of turning shaft for regulating the angle, it gains the cornice planed impression effect. With the characteristics of firm structure, resisting seismic and wind, convenient to install and dismantle, the whole system can adjust to the deformation of the grid roof, greatly shorten the construction period and keep the project costs down.
