点支式玻璃幕墙支承体系的分类及构件性能分析

Classification of bearing system of point-supported glass curtain wall and performance evaluation of its components

点支式玻璃幕墙体系以良好的通透性和安全性以及优美的建筑表现在国外获得广泛的应用,随着我国建筑材料生产技术的发展和现代建筑艺术造型的兴起,点支式玻璃幕墙这种新的建筑形式在我国也得到了快速的发展。玻璃幕墙出现在各种不同风格的建筑物上,因此也产生了不同的幕墙结构体系。本文通过点支式幕墙的支承分类、不同支承结构特点的论述以及主要组成材料的技术分析,对不同结构体系的点支式玻璃幕墙的设计原则和在实际工程施工中需解决的技术问题进行了论述,阐明了点支式玻璃幕墙的一般设计规范、不同幕墙支承体系的设计要点和技术分类,同时对不同幕墙支承结构的材料组成在技术层面上作了充分的论证,希望能够对国内类似的点支式幕墙结构的应用提供一些参考。

Point-supported glass curtain wall gained a wide range of applications in abroad because of its good transparency,safety and excellent performance.Along with the development of building material and modern architectural shape,this novel architectural appearance has seen rapid development.There are various glass curtain wall system because of the different architectural style.In this paper,the bearing classification of point-supported glass curtain wall and the characteristics of bearing structure are presented,the design principle of different point-supported glass curtain wall system and the problems in practical application are discussed,the general criterion and main points in design and the technical classification of point-supported glass curtain wall are introduced,and the technical evaluation of the various bearing structure of point-supported glass curtain wall are discussed.
