金属屋面的渗漏及维修

金属屋面常因环境温度变化、节点部位不同、材料应力变化差异以及使用日久等原因产生渗漏,维修时应从选择优质防水材料、有针对性的方案设计以及有序的施工三方面展开工作。本文详细描述了金属屋面渗漏维修时的各类工程案例,包括高分子卷材机械固定维修(含防结露维修)、高分子卷材满粘维修以及有、无胎基涂料维修等,给出了不同翻修屋面的构造层次及具体做法。

Leakage and Maintain of Metal Roof

There are many causes of the metal roof leakage,such as ambient temperature fluctuations,joints,material’s stress variation,long-time service,and so on.The maintain work should be carried out in three aspects which are the selection of waterproofing materials,specific design plan and orderly construction.The paper presents various maintain cases of metal roof leakage,such as maintain by polymer membrane with mechanical fixing,maintain by polymer membrane with full adhesion,maintain by coating without reinforcement,and so on.It provides different roof structural layers for repair and their construction steps.
