Is it possible to install a lightning rod directly on a house?
The direct use of building wall columns reinforced when the lead line, home building generally four corners, with four diagonal corner posts (two) as the lead line, the two best use of reinforcement lap welding, welding length not less than 6 times the diameter of the reinforced (double welding), single-sided welding not less than 12 times the diameter of steel bar. Four prism deflectors leads to the use of 12mm reinforced roofing galvanized steel bar length 500mm when the lightning rod, welding welding port connectivity, embedded in the concrete, and then along the parapet four roots of lightning rod with 12mm welding galvanized steel bar into a ring, ring of lightning with a fixed frame, each 1000mm arranged a fixed frame using the same material fixed.Above lightning protection practices, household words, basically no problem.
The drawing line can be welded with 12mm galvanized round steel and the ground body, which is higher than 300mm from the roof, and should be installed on each corner of the roof, welded and communicated with the antirust paint on the welding joint.
Steel grounding device of vertical buried body with a diameter of not less than 50 mm, the wall thickness of not less than 2.5 mm, or less than 50 mm x 50 mm x 5 mm angle, sometimes using the diameter of not less than 19 mm. The grounding body length is generally 2 to 2.5 meters, steel pipe into underground end processing a bevel shaped or flat or round angle into the pointed end processing needle. Before installing the grounding body, it is necessary to dig trenches along the line of the grounding body so as to facilitate the grounding of the grounding body and the convenient laying of flat steel and round steel for connecting the grounding bodies, and the groove depth is generally more than 0.6 meters.
