27、是逐个在工地安装要求相对较长的工期。会话韦一迈克.韦伯（跨国公司的首席执行官。他想请贝先生为其设在北京的亚太地区总部设计办公大厦。）贝一贝聿铭（世界著名的建筑师，贝氏建筑师事务所的创始人。）贝：亲爱的韦伯先生，欢迎您到贝氏建筑师事务所。韦：谢谢您，贝先生。您的设计作品（尤其是香港中银大厦）给我留下深刻的印象。您是在1982年设计的这座368米高的建筑物。25年已经过去了,它仍然保持着独有的时尚和雄伟，并成为香港特别行政区的标志性建筑。贝：谢谢。它所表现的时尚感要部分地归功于所采用的明框幕墙结构。韦：什么是明框幕墙？贝：正如您所能看到的，明框幕墙的特点就是框架暴露在外。韦：我认为如果框架不外露会

28、产生更好的视觉效果。贝：隐框幕墙的框架不外露。面板之间通过硅酮密封胶密封。10韦：如果将明框幕墙和隐框幕墙的特点综合一下，结果会怎样?贝：这就是半隐框幕墙。面板有两组对边。一组对边用镶嵌梢安装，另一组对边使用结构密封胶安装。韦：面板是如何固定在镶嵌梢内的？贝：有三种方法：1应用密封条的干式装配法，2应用密封胶的湿式装配法，3混合使用密封条和密封胶的混合装配法。我们更倾向采用最后一种方法，因为它的水密，气密效果较好。韦：在地震过程中和风荷载下，镶嵌梢夹持法是否比结构胶固定法提供更有效的连接？贝：恐怕不是这样。镶嵌梢夹持法通过“强化”结构，从而达到抗震的目的。在风荷载下它限制面板的变形。这时，面板

29、（尤其是玻璃面板）有可能被憋断。硅酮结构胶固定法通过“软化”结构硬度化解地震的作用力。在风荷载下，结构胶随面板的运动而拉长。韦：具我所知，有很多种密封胶，例如：聚硫密封胶、聚氨酯密封胶、丙烯酸酯密封胶、丁基密封胶，氯丁密封胶等等。它们也可以作为结构胶使用吗？贝：不可以。只能选用硅酮结构密封胶。硅酮结构密封胶的主要成分是聚硅氧烷，有很好的抗紫外线能力，所以其抗老化性能很强。韦：虽然，结构胶很可靠，但是我还是认为框架外露的明框幕墙给人的感ii觉更安全一些。贝：有很多建筑师也这样认为，所以他们在隐框幕墙上加压板。这样可以起到对结构的加固和装饰作用，更重要的是增加了安全感。我们称这种幕墙为“假半隐框幕墙”。韦：幕墙面板是什么材料的？贝：有玻璃、石材、铝板、搪瓷钢板等。其中，玻璃
