Lightning Protection Artificial Grounding System and Construction Method Using Structural Reinforcement to Externally Connect Down Conductors

Abstract

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.

Description

technical field [0001] The invention relates to the field of building lightning protection construction, in particular to a lightning protection artificial grounding system utilizing structural steel bars externally connected to down conductors and a construction method thereof. Background technique [0002] Lightning is a common natural phenomenon. It can produce strong flashes and thunderbolts. Sometimes it falls to the ground, destroys houses, kills people and animals, and brings great harm to human beings. Especially with the rapid development of my country's construction industry, high-level With the increasing number of buildings, how to prevent the harm of lightning and ensure the safety of buildings, equipment and personal is even more important. [0003] Lightning protection and grounding are the most important matters related to the safety of buildings and personal lives. When lightning strikes, a strong current passes through, which produces mechanical force and th...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: aiming at the problem that the existing lightning protection down conductor only utilizes structural steel bars in the building, so that it is limited to the problem of slab-type foundation buildings, to provide a lightning protection artificial The grounding system and corresponding construction methods are not limited by independent foundations, strip foundations, pile foundations, slab foundations, etc., and the scope of use is extended
