Can the steel bar in the reinforced concrete column be extended to make lightning rod after heightening?
The lightning rod is one of the lightning arresters, and the lightning arrester is an important component of the lightning protection device. Flash device requirements: 1., must be smooth surface, no rust, easy to discharge the shape of conductive metal; 2., it must have good electrical access to the ground.
May not。 Lightning protection requires good conductive metal or galvanized on top of iron. You can galvanized when the steel bar is lengthened. If the supervisor would like to
Besides concrete exposed steel bars, will attract the corroded continuously into the internal structure, reduce the fatigue life of the components.
Reinforced concrete column in steel exposed, the extension of the Gago, a few weeks before the scar do not rust Lai, not easy to discharge; and, with the grounding of electrical flow is not reliable, when not connected, "lightning" became "ray."!
This practice in the residential building, the premise is the basis to do must be reinforced in grounding for lightning protection and reinforcement, not too small, less than 14 to 4 to 2 greater than the root, root, and the steel from the start with the flat base jumper do, each layer is to be welded reliably. And reliable connection with the grounding of grounding.
