step two, spraying fluorocarbon paint on the surface of the channel aluminum; after the paint is dried, fixing the groove aluminum on the top of the parapet wall by using the pre-embedded bolt, and forming a closed loop along the top of the parapet wall of the roof;
and step three, connecting the copper-clad steel round wire with the aluminum groove at the top of the parapet wall, then using the copper-clad steel round wire as a down-lead to be exposed along the outer wall, and finally connecting the down-lead of the copper-clad steel round wire with the total grounding grid of the factory building.
The embedded bolts are M10 bolts, and the distance range is 1.5-2.0M.
The specification of the groove aluminum is that the width w, the height b and the wall thickness t are 200mm multiplied by 100mm multiplied by 2 mm.
The specification of the copper-clad steel round wire is
The copper-clad steel round wire.
The parapet wall is 300-1200 mm in height and 150-250 mm in thickness.
The down leads are laid at a horizontal interval of 12-25 m.
The invention has the beneficial effects that:
the channel aluminum has excellent conductivity, and the channel aluminum sprayed with fluorocarbon paint has better corrosion resistance in chloride-containing atmospheric environment, and is cheap, good in plasticity and convenient to process; the parapet wall coping groove aluminum decoration with proper shape and section size is selected to be used as the lightning protection belt to replace the lightning protection belt which integrally adopts the copper-clad steel round wire, so that the problem of installation space of the lightning protection belt can be solved, the requirement of consistency of overall sense of a factory building wall body can be met, and the parapet wall coping groove aluminum decoration has the advantages of reasonable structure, simple method, corrosion resistance, good safety, low cost and long service life.
