Embodiment Construction
[0042] Such as figure 1 Shown is a lightning protection artificial grounding system that utilizes structural reinforcement externally connected to the down conductor, including a structural reinforcement down conductor 2 fixed in the building structure exterior wall column 1 and connected to the lightning receptor on the top floor of the building. The lightning protection artificial grounding system The down conductor of the structure is composed of a structural steel bar down conductor 2 and a non-structural steel bar down conductor 5. The structural steel bar down conductor 2 is vertically arranged on both sides of the structural outer wall column and connected by a jumper wire 3. The structure The steel bar down conductors 2 need to be grouped, and one of each group of structural steel bar down conductors 2 in the underground part is fixed with a connecting plate 4 laterally, and the connecting plate 4 is externally connected to the non-structural steel bar down conductors 5...
