Product Introduction

The protection against direct lightning strikes in high-rise buildings emphasizes the basic principle of using exposed lightning arresters. According to Appendix 2 of the "Code for Design of Lightning Protection of Buildings" GB50057-94, which specifies specific and clear locations, metal lightning arresters shall be installed in all vulnerable areas of the building, such as the ridge, corners, eaves, edges of corners, parapets, roof frames, floating boards, roof stairs, roofs, and around the top of water tanks. Three types of lightning protection buildings should form a closed grid of less than 1T or equal to 20mx20m or 24mxl6m on the entire roof.
Although there are clear examples in the "Installation of Lightning Protection Settings for Buildings" (99 [) 501-1), due to defects in the installation method of lightning protection strips in the standard drawing set, based on practical experience in areas with severe lightning disasters, it is recommended to take the following technical measures to improve lightning protection sensitivity:
1. Firstly, emphasize the importance of installing on the outer side of the parapet wall. If the distance from the outer edge is less than or equal to 375px, there should be a gutter on the roof
The lightning protection belt should be laid on the daughter wall outside the gutter. Support card height of 15-500px, with a spacing of 80-2500px, and 750px at corners.
2. Install short lightning rods on the lightning protection strip at the corner of the building.
3. Extend the lightning protection strip at the corner of the sun in two directions, extending it straight and extending it 5-250px beyond the outer side of the wall to form a closed circular connection.
4. When there are railings on the terrace or daughter wall of a duplex building, the railings should be reliably grounded and replaced with lightning protection belts.
5. The top balcony canopy on the outer side of the building should have lightning protection measures, and it is best to lay lightning protection strips on the edges; Can be utilized in low rise buildings
The steel bars inside the structure are concealed with lightning arresters.
6. Let the lightning protection belt truly play its lightning protection and lightning protection function, effectively avoiding similar lightning accidents.
