摘　　要：铝镁锰合金金属屋面具有轻质高强、安装方便、可维护性强等特点,在高铁站房项目中得到广泛应用。但在台风和强风作用下,不少金属屋面发生局部掀起、脱落和渗漏水现象。因此,以某高铁站房为例,应对金属屋面面积大、工期短、板面收缩变形大、天沟等部位抗风揭薄弱等难点,通过钢屋盖、金属屋面一体化深化设计,优化钢桁架杆件及屋面构造,提高了直立锁边金属屋面的施工效率,同时,对金属板特殊部位采取节点加强措施,解决了收缩变形、抗风揭薄弱点,可为今后类似工程提供参考。Aluminum-magnesium-manganese alloy metal roofs,known for their lightweight,high strength,ease of installation,and strong maintainability,are widely used in high-speed railway station projects.However,under the influence of typhoons and strong winds,many metal roofs experience local uplifting,detachment,and leakage.Taking a high-speed railway station as an example,challenges such as large roof area,short construction period,significant panel shrinkage and deformation,and weak wind resistance at gutters and other parts are addressed through the integrated design optimization of the steel roof and metal roof.It improves the construction efficiency of standing seam metal roofs.Additionally,node reinforcement measures are applied to specific parts of the metal plates to resolve issues of shrinkage deformation and weak wind resistance,providing a reference for similar projects in the future.
