Summer thunderstorms occur frequently, and what is the lightning protection ability of various landscape membrane structures or membrane structure carsheds that can be seen everywhere? Is it safe to shelter under membrane structures during thunderstorms? Around these problems, today Xiaobian will introduce the lightning protection design of the membrane structure.
The statistical characteristics of lightning strike vary greatly with different building forms and building sites. Some places do not necessarily appear lightning strikes throughout the year, but some places will occur frequently, for these two areas, the former can use lightning rod, the latter must be installed lightning belt, according to the film surface coverage space can be calculated conductive power, the design of conductive power must meet the local lightning statistical characteristics of the requirements of the value.
Many people have doubts about the lightning protection ability of such membrane structure buildings, because they can not see the obvious lightning protection device in membrane structure buildings, whether it is a large membrane structure sports stadium, commercial roof hollow or small landscape membrane structure or membrane structure shed, it is rare to see additional lightning rod or lightning belt facilities. In fact, when our common steel mast and column supporting the film surface are painted or galvanized anti-corrosion, they can be directly used as lightning arrester and vertical grounding wire (very few masts are anti-corrosion such as spraying plastic, in this case, lightning arrester should be added). In general membrane structure buildings, the high point is generally designed to highlight the mast, in fact, this is the invisible lightning protection device, but it is designed to be more beautiful and practical. It should be noted that the foundation concrete resistance is large, generally does not meet the lightning conductive requirements, so the mast base should be attached with an effective grounding wire.
Formal experienced membrane structure design units or membrane structure companies, their engineering works will help customers consider all aspects of the problem, without customer reminders will be lightning protection design will be chimed into the project; On the contrary, many novice construction units that solicit low-cost projects are not very particular in this regard, leading to uneven quality of membrane structure engineering on the market, which leads to the lightning protection and lightning protection ability of some membrane structures is very unstable, and we need to judge whether it is safe or not according to the site situation.
That’s “Is it safe to shelter under membrane structures during thunderstorms?” The introduction of. Here, Yexing membrane structure Company reminds you that it is still possible to shelter under normal intact membrane structure buildings during thunderstorms, but do not touch the steel structure column when sheltering, and try to stay in a dry area.If you want to know more about ETFE membrane structure, please add our official WhatsApp: +86-13923448766, or send an email to our official email: yexing@yexinggroup.com.
