［摘要］基于重庆仙桃数据谷项目，介绍了构件单元组合式幕墙系统设计与施工技术的主要内容。由于重庆仙桃数据谷项目的建筑幕墙立面采用麻花形的扭曲收腰式构造，为幕墙的建造带来了很多有别于常规幕墙的挑战；基于构件单元组合式幕墙系统，应用基本单元板块间打胶连接和分体组合式横梁，解决双向曲面玻璃幕墙的造型扭转、竖向连接定位和防水难题；利用BIM技术、三维扫描和可伸缩调节双轨挑架，提高了施工精度、缩短了建造周期、节约了安装成本，可以为类似幕墙工程的建造提供参考。

Abstract:Based on  Chongqing Xiantao Data Valley Project, the main contents of the design and construction technology of component-unit composite curtain wall system were introduced. The facade of the building curtain wall of Chongqing Xiantao Data Valley Project adopted twisted waist structure, which brought many challenges to the construction different from the conventional curtain wall construction. Based on the component-unit composite curtain wall system, the application of gluing connection between basic unit plates and split combined beam solved the problems of twisted waist structure, vertical connection positioning and waterproof of the glass curtain wall with bidirectional curved surface. By using BIM technology, three-dimensional scanning and adjustable double-track cantilever frame system, the construction accuracy was improved, the construction period was shortened, and the installation cost was saved, providing reference for the construction of similar curtain wall projects.

Keywords:torsional glass curtain wall; component-unit composite system; split combined beam; double-track cantilever frame system
