Lightning protection downlead and construction method thereof
The invention discloses a lightning protection downlead and a construction method thereof. The downlead comprises an upper end metal conductor, a lower end metal conductor and main reinforcements in prefabricated frame columns. Two up and down adjacent prefabricated frame columns are mutually connected at a building floor. All the main reinforcements in the two up and down adjacent prefabricated frame columns are connected at the building floor through grouting. At least one main reinforcement in each prefabricated frame column is selected and is served as a conductive main reinforcement. Two ends of the conductive main reinforcement are welded with the upper end metal conductor and the lower end metal conductor. The upper end metal conductors and the lower end metal conductors of the two up and down adjacent conductive main reinforcements are mutually welded in the building floor. Compared to the prior art, by using the lightning protection downlead and the construction method in the invention, there are the following advantages that the main reinforcements which can not form continuous conductors form the continuous conductors so that a metal conductor lightning protection downlead which connects a roof lightning arrester and a grounding device is formed; requirements of direct lightning prevention, lightning surge intrusion prevention and a lightning electromagnetic pulse can be satisfied.
