Lightning-protection manual grounding system and construction method by utilizing structure steel bar externally-connected downlead wire
The invention discloses a lightning-protection manual grounding system and a construction method by utilizing a structure steel bar externally-connected downlead wire. The system comprises a structure steel bar downlead wire (2) fixed into a building structure outer wall column (1) and connected with a lightning arrester on the top of a building. The lightning-protection manual grounding system is characterized in that the downlead wire of the lightning-protection manual grounding system is formed by the structure steel bar downlead wires (2) and a non-structural steel bar downlead wire (5). The structure steel bar downlead wires (2) are connected to form a group through jumper wires. The portions, under the ground, of the structure steel bar downlead wires (2) are transversely and fixedly provided with a connection plate (4); and the connection plate (4) is externally connected to the non-structural steel bar downlead wire (5) which is connected with a manual grounding body (6). The lightning-protection manual grounding system is suitable for the practice that in a reinforced concrete structure, structure steel bars and non-structural steel bars jointly serve as the downlead wires, and the manual grounding body or a composite lightning protection grounding device are used, and limitation of independent foundation, strip foundation, pile foundation and slab foundation and the like is not the case.
