Introduction to use knowledge of lightning tower
2023-03-15
Lightning tower is a common tower type lightning protection device. Alias: lightning rod tower, steel structure lightning rod, tower lightning rod.
There are four specifications of lightning tower: 1. GFL four-column angle steel lightning tower, 2. GJT three-column round steel lightning tower, 3. GH steel pipe pole lightning tower; 4. GFW lightning tower.
Lightning towers are specifically divided into GFW series, GFL series, GH series, single-tube lightning towers, and three-column round steel lightning towers, which are generally 20 to 40 meters high. There are more GFW and GFL series widely used.
The protection radius and protection range of lightning rod tower shall be calculated according to the rolling ball method.
Lightning towers are mainly used for lightning protection works of various buildings, especially oil refineries, gas stations, chemical plants, coal mines, explosive stores, flammable and explosive workshops. Lightning towers should be installed in a timely manner. Due to climate change, lightning disasters continue to increase. Now many buildings are installed with lightning towers, especially the stainless steel decorative iron towers on the roof. They have various shapes, beautiful shapes, novel and unique designs, and are widely used in the roof of various buildings The buildings such as the square and the green space in the residential area make them complement each other and become the landmark decoration buildings in the city. The principle of lightning tower is the same as that of lightning rod. Reduce lightning disasters.
Service conditions
1. Basic wind pressure: w0=0.4 and 0.7KN/m2
2. Seismic fortification intensity: 8 degree and small day 8 degree area
3. Foundation bearing capacity: 100 and 200 KN/m2
4. Ice thickness: ≤ 10mm 5. Verticality: ≤ 1/1000
design basis
1. Code for Design of Lightning Protection of Buildings (GB50057-94)
2. Code for Design of Tall Structures (GBJ135-90)
3. Code for Design of Steel Structures (GB50017-2003)
