摘　　要：主题乐园一般为高大空间场所,以金属板作为屋面,屋顶附着突出的高大金属构件,其防雷设计与普通混凝土屋面不同.本文分析了主题乐园建筑金属屋面防雷设计和施工的特点,在确定防雷等级、金属屋面是否可作为接闪器、对大面积金属屋面及高耸乐园防侧击雷以及多种金属混合屋面的防腐蚀处理技术进行了分析总结.从接闪器、引线下及接地装置三个方面分析了主题乐园建筑金属屋面的实现防雷安全的构造措施和做法.Theme parks are generally tall and large spaces and the roof is made of metal sheet attached with tall metal components and fandangle.Its lightning protection design is different from that of ordinary concrete roofs.The lightning protection design and construction of the metal roof of theme park buildings is analyzed in the paper.Classifying the lightning protection level,determining whether the metal roof can be used as an air-termination device,preventing side lightning from large-area metal roofs and towering buildings,and anti-corrosion treatment technology multi-metal mixed roofs was analyzed and summarized.The detail construction measures and practices of lightning protection safety of metal roof of theme park building are discussed from three aspects of air-termination,down-conductor and earth-termination.
