How to install lightning protection measures?
The first line at both ends of the bracket is buried, and then pull line laying the middle bracket, corner bracket should be 0. 25-0. 5m from the turning point.The horizontal spacing of the bracket is 1-1. 5m, the vertical spacing is 1. 5-2m, and the bracket spacing should be evenly distributed.Lightning belt (net) installation bracket is fixed on the building on the gutter, with construction to set up the embedded bracket and the embedded parts are welded and fixed.
Lightning protection belt is installed on the roof or cornice, support bracketFix with a concrete support or support.Cast-in-situ bearing, the ridge knock off a corner, make the mortar support and ridge in together;The bracket is fixed, the drill will need tile drilling, then the support is inserted into the hole with cement mortar packing firm.Bearing and support, the horizontal spacing is 1-1. 5m, and the corner is 0. 25m-0. 5m.The connection between the upper end of the lead line and the lightning belt (net) shall be bent into an arc, and then welded with the lightning belt (net).Different planes of the lightning belt (mesh) should be at least two connected to each other, the connection should be welded.The projecting metal objects on the roof of a building, such as flagpole, ventilation pipe, iron railing, climbing ladder, cooling tower, TV antenna rod, etc., all the metal conductors of these parts must be welded together with the lightning belt (net).
1. installation of Lightning Arresters (NETs)Suitable for installation in building roof, roof (roof slope) or the edge of the roof and parapet (flat roof) etc..(1) installation of lightning conductor on roof concrete support;The support of the lightning belt (net) can be poured in place during the construction of the roof surface of the building, and can be prefabricated or repaired or fixed with the waterproof layer of the roof.(2) lightning with the parapet or gutter bracket installationAlong the parapet when installed, should use the bracket; and should be with the construction of embedded bracket. The support height shall not be less than 150mm.When the condition is limited, the hole shall be reserved not less than 100mmx, 100mmx and 100mm in the construction of the wall, and the size of the hole shall be consistent both inside and outside.
The installation of lightning rod (lightning arrester) mainly includes the installation of lightning rod and the installation of lightning belt (net).(1) installation of lightning rodInstallation notes are as follows:(1) the lightning rod on the building and other metal objects at the top of the building shall be connected as a whole.(2) no low voltage line or communication line shall be erected on the lightning rod frame.
