Product Introduction
Direct lightning protection of high-rise buildings emphasizes the basic principle of using exposed air terminals. In accordance with the provisions on specific and clear locations in Appendix B of the "Building Lightning Protection Design Code" B, the building's roof ridges, corners, eaves, eaves corner edges and parapets, roof frames, floating slabs, roof ladders, roofs, pools All parts that are susceptible to lightning strikes, such as the roof and surrounding areas, are equipped with metal air-termination devices. Category III lightning protection buildings should form a closed grid less than or equal to 100% on the entire roof.
Although there are clear examples in "Lightning Protection Installation of Buildings" ([)1), there are flaws in the installation method of lightning protection strips in the standard atlas. Based on the practical experience in areas with severe lightning disasters. It is recommended to take the following technical measures to improve the lightning sensitivity:
First, emphasize the importance of installing it on the outside of the top of the parapet. The distance from the outer edge is less than or equal to that, and there is a gutter on the roof
When the lightning protection strip should be laid on the parapet outside the gutter. The card height is supported, the spacing is appropriate, and the corner is 3.
. Install short lightning rods on the lightning protection strips at the corners of the building.
Extend the lightning protection strip at the corner of the sun corner straightly in two directions, beyond the outside of the wall to form a closed circular connection.
When there are railings on the terrace or parapet of a duplex building, the railings should be reliably grounded to replace lightning protection strips.
The top balcony awning on the outside of the building should have lightning protection measures. It is best to use lightning protection strips exposed on the edges. When building low-rise buildings,
the steel bars in the structure can be covered with air-termination concealed.
Let the lightning protection belt truly exert its lightning protection function and effectively avoid similar lightning accidents.
