建筑物幕墙防雷作法探讨

Discussion about Lightning Protection Approach for the Curtain Walls of Buildings

以建筑物幕墙防雷工程为例,针对建筑物幕墙金属结构的特点,从幕墙防雷的接闪、引下、均压、接地等方面讨论了幕墙防雷的技术,并提出了施工中应注意的问题,如伸缩或沉降缝的处理、连接点间距的限制、焊接点与非焊接点的连接要求等。

Taking the lightning protection engineering for the curtain walls of buildings as an example, aimed at features of the metallic structure of the curtain wails of buildings, the techniques for lightning protection of curtain walls are discussed on the aspects of lightning receiving, downward leading, voltage equalization and grounding. The points for attention in the construction are put forward： treatment of expansion and settlement joint; limitation of the spacing between connecting points; connecting requirements to welding points and non-welding points, etc.
