扫码查看
分析了超高层建筑在防雷设计中的关键技术问题.依据现行国家标准的规定要求,从安全可靠、经济合理、切实可行的角度出发,通过总结长期以来从事的建设项目的机电顾问、建筑防雷施工图设计和防雷技术审查工作中的实践经验,提出了超高层建筑防雷设计中关于地闪密度值取值、等效面积计算、防侧击与均压环设计、接地干线与接地端子位置选择等问题处理的技术意见,对超高层建筑的防雷接地设计有一定的指导意义.
Analysis and Discussion of Several Technical Issues in the Lightning Protection Design of Super High-Rise Buildings
This article analyzes the key technical issues of lightning protection design in super high-rise buildings.Based on the requirements of current national standards,starting from the perspectives of safety,reliability,economic rationality,and practical feasibility,and by summarizing the practical experience in consulting for construction projects,lightning protection design,and lightning protection technical review over the long term,technical issues such as the selection of ground flash density values,calculation of equivalent areas,design of lateral protection and equipotential rings,and the selection of grounding main lines and grounding terminals in lightning protection design for super high-rise buildings are proposed.The aim is to provide certain guiding significance for the lightning protection and grounding design of super high-rise buildings.
