摘　　要：武汉中心幕墙上下两排单元体错开半个单元体位并呈鱼鳞状,每个立面上下整体呈弯弧形,其防水设计主要采用系统性的构造防水,利用雨幕原理在幕墙接缝部位的内部设置一定的空腔形成一种等压状态,从而可以将大部分雨水阻挡在墙壁之外。幕墙四性实验表明该设计合理可靠,可为类似超高层幕墙的防水设计及施工提供参考。The up and down rows of unit curtain walls of Wuhan Center are installed with half unit space staggering each other, like fish scale, and each vertical face is curved overall. The waterproofing design mainly adopts systematic structure waterproofing, and using the principle of rain curtain, some cavities are built inside the curtain wall joint location to form an isobaric state, thus, most of the rainwater can be stopped outside of the walls. The four properties testing of curtain wall shows this design is reasonable and reliable, and it can be reference for the waterproofing design of similar super high-rise curtain walls.
