In the entire frame house, the beam column reinforced connection end, whether the lightning rod can be struck by lightning or not
The natural metal compounds on the use of the building as a natural lightning arrester "covered with metal roof structure of non metal (steel truss, the network connected to each other and so on), when the non metal in electric space"; in the 2.2.5 clause, the natural metal utilization of buildings as a natural lead including "the structure of the interconnected mesh reinforcement";
Article 3.3.5 the use of reinforced concrete columns and steel bars in the foundation as the lead line and grounding body, at home and abroad in the early 60s has been adopted. Is now more common. The use of roof steel as a lightning arrester has been adopted gradually at home and abroad since the early 70s.
The premise is that you connect the lightning rod in the house of steel must be a whole, pay attention to the electrical whole, and the grounding resistance must be less than 10 ohms, that is no more than 10 ohms, the smaller the better. Fear is that your rebar is not even good, the house becomes a cement resistance, it would be troublesome.Also, before the thunderstorm season, it is necessary to measure the grounding resistance value. The resistance is great, and measures should be taken to reduce it.
