论文摘要
[摘要] 上海华润新鸿基万象城购物中心金属屋面整体呈弧形,采用钛锌板金属压型钢板制作,充分利用钛锌板系统高强、对曲线完美贴合、耐久性好的优点。通过研究屋面系统构造,指出固定座、收边泛水、天沟系统安装是施工重点,并介绍了屋面系统安装施工工艺和施工流程。通过严格控制固定座的水平位置偏差、倾斜角度及平面角度,天沟系统采用EPDM不锈钢伸缩带、设置构造伸缩缝等技术措施,保证了工程施工质量。

Construction Technology of Zinc-titanium Alloy Plate System Metal Roof
on Some Shopping Center in Shanghai 
Abstract:Because of advantages of zinc-titanium alloy plate system such as high strength, perfect surface-fitting property and good durability, it is used in arc metal roof of Huarun Xinhongji Wanxiangcheng shopping center in Shanghai. By researching the structure of roof system, it is proposed that the installation of fixing supports, flashing and gutter system is key point during construction. Furthermore, construction technology and process of roof system are introduced. Construction quality is ensured by taking some construction measures, including strictly controlling horizontal deviation, inclination and plane angle of fixing supports, choosing EPDM stainless s
teel expansion band for gutter system and setting structural expansion joints in gutter and so on.     
Key words:metal roof; zinc-titanium alloy plate system; installation; construction technology; technology measure
