In modern high-rise buildings, it is easy to attract lightning strikes. Therefore, when building high-rise buildings, relevant lightning protection inspection facilities are installed. What other major lightning protection facilities are there in addition to well-known lightning rods in new buildings?
1, artificial conductor grounding device
This kind of metal conductor is used as a grounding device buried in soil or concrete base layer, which can play the role of lightning current dispersion, so when the building is in construction, the lightning protection detection mechanism proposes that the building should be laid around the building in a circular shape around its circumference. Grounding devices, in addition, grounding devices such as electrical and electronic equipment and other facilities are also best to share a grounding body, and receive professional lightning detection after construction.
2. Natural grounding device
The natural grounding device is the use of the reinforced structure of the building itself as a lightning protection ground. The lightning protection detection agency tells us that the prerequisite for using the natural grounding is that the steel bar in the basic structure meets the construction specification of the lightning protection facility. During the construction, the two steel bars in the upper part of the building's surrounding ground beams shall be welded into a horizontal grounding body, and the two steel bars in each pile shall be used as the vertical grounding body for the welding of the steel reinforcement on the pile cap.
3, pressure ring
The introduction of lightning protection detection agencies, if the building is a comprehensive building, you can set the pressure ring from the first floor to the top floor as required. Starting from the critical height, every second floor is to weld two main tendons in the upper part of the outer ring beam of the building, and to form a closed passage by communicating with the downleads, thus forming a pressure equalizing ring for lightning protection.
