上海某购物中心钛锌板系统金属屋面施工技术 黄成1 俞水其2 （1上海师范大学基建规划处，上海 201418; 2浙江东南网架股份有限公司　杭州　311209） [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。 [关键词] 金属屋面；钛锌板系统；安装； 施工工艺；技术措施 [中图分类号]TU758.1 [文献标识码]A [文章编号]1002-8498（2009）05-0108-03 Construction Technology of Zinc-titanium Alloy Plate System Metal Roof on Some Shopping Center in Shanghai HUANG Cheng1 Yu Shuiqi2 (1 Capital Construction Planning Department of Shanghai Normal University, Shanghai 201418, China; 2 Zhejiang Southeast Space Frame Co.; Ltd.; Hangzhou 311209) Abstract: Because of advantages of zinc-titanium alloy plate system such as high strength, perfect surface-fitting proterty and good durability , it is used in are metal roof of Hunrun Xinhongji Wanxiangcheng shopping center in Shanghai. By researching the structure of roof system, it isproposed 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 horizontal deviation and plane angle of fixing supports, choosing EPDM stainless steel expansion band for gutter system and setting structural expansion joints in gutter and so on.
