Embodiment 1

[0061] The embodiment of the present application takes the application of the lightning protection structure on the bridge pier as an example, but it is not limited to this scenario, and other aspects will not be repeated.

[0062] The electrical effect, thermal effect, and mechanical force generated by lightning strikes may cause damage to the bridge structure: endangering personal safety, damaging the main structure of the bridge, and damaging electronic and lighting equipment on the bridge deck.

[0063] Lightning protection equipment or devices should include lightning receptors, down conductors, grounding devices, surge protectors and other connecting conductors; it should be noted that lightning receptors are lightning rods, lightning protection belts, lightning protection nets that directly receive lightning strikes, and It is used as a metal component for lightning; the down conductor refers to the metal conductor used to connect the lightning terminal and the grounding...

Abstract

The invention provides a lightning protection structure and a bridge pier, and relates to the technical field of building lightning protection. The lightning protection structure comprises grounding terminals, flexible connecting wires and at least one set of downleads; each downlead comprises a plurality of downlead segments arranged in sequence in the length direction, and one grounding terminalconnected with the downlead segment is arranged at the end of each of the downlead segments, and every two adjacent grounding terminals are connected through a connecting wire. Further, the groundingterminal is arranged at the end of each of the downlead segments, and the embedding of the downleads and the grounding terminals does not require a high-precision positioning process, and only requires a certain gap with a main reinforcement in the component; every two adjacent grounding terminals are connected by one flexible connecting wire, and the operation is simple and reliable; by adoptingthe lightning protection structure, the effective connection between the downleads reserved inside each component is ensured, and a good electric path is formed between the lightning protection structures, thereby constituting a complete lightning protection system.

Description

technical field [0001] The invention relates to the technical field of building lightning protection, in particular to a lightning protection structure and a bridge pier. Background technique [0002] The electrical effect, thermal effect and mechanical force generated by lightning strikes may cause damage to the structure of the building: endangering personal safety, damaging the main structure of the building, and destroying electronic and lighting equipment on the building. [0003] Lightning protection equipment or devices should include lightning receptors, down conductors, grounding devices, surge protectors and other connecting conductors; The down conductors may not be effectively connected, resulting in the inability of the lightning protection device in the prefabricated building to penetrate and form a good electrical path. As a result, the lightning protection system is not perfect, which not only endangers personal safety, but also easily damages prefabricated ...
