ⅤTranslation(汉语译文)
技术简介
框架式幕墙是先将横框、竖框及面材在工厂进行加工,然后运到工地现场安装的幕墙结构。
在现场先通过转接件将竖框安装在主体结构上,再将横框连接在竖框上。
形成幕墙框架体系后,安装固定面板。
框架式幕墙可以分为明框幕墙,隐框幕墙和半隐框幕墙
框架式幕墙的优点是运输方便并且运费低廉,但是逐个在工地安装要求相对较长的工期。
会话
韦—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—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。
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。
一组对边用镶嵌槽安装,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槽内的?
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,镶嵌槽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。
镶嵌槽夹持法通过“强化”结构,从而达到抗震的目的
