我国与阿尔及利亚建筑物防雷设计与施工对比

摘要

对比中阿两国在防雷接地系统设计和施工方面存在的差异；比较铜接地体与热镀锌扁钢接地体的性能；介绍阿尔及利亚工程所用裸铜线及其特制配件；总结接地系统的施工方法。结合实际案例，对建筑物防雷引下线的选择、使用，接地体的设置等问题提出具体方案；强调建筑物外部防雷设计应与结构专业协调配合。%Difference in design and construction of lightning protection and grounding systems in China and Algeria is compared; earth electrode performance of copper and that of hot-dip galvanized flat steel is compared. The bare copper wire as well as its special accessories applied to projects in Algeria is introduced. The construction methods of grounding system are summarized. Combined with actual engineering cases, specific schemes on selection and application of lightning protection down-conductor system for buildings and setting of the earth electrode are put forward. In addition, it is emphasized that the external lightning protection design of buildings should be combined with the structure discipline.
