北京达美中心广场幕墙工程采用胶条插接式双腔构造,设计思路沿袭了传统单元式幕墙等压腔防排水原理,保持了胶条插接式幕墙的诸多优点;同时,在风压过大情况下,有少量雨水进入幕墙腔体内部时也可顺利排出室外,不会产生雨水滞留,可为特殊环境下幕墙的防排水功能提供有力保证。 Beijing Delta Central Plaza curtain wall project uses plastic plug-in dual-chamber structure, the design concept followed the traditional unit curtain wall pressure cavity waterproof principle, to maintain the advantages of the plastic plug-in curtain wall; the same time, In large cases, a small amount of rainwater can enter the interior of the curtain wall and can be smoothly discharged outdoors without rainwater retention, which can provide a strong guarantee for the drainage and drainage function of the curtain wall in a special environment.
