Rows of dark blue photovoltaic panels are neatly arranged, and the solar panels shine in the sunlight. Photovoltaic bracket is more and more widely used, photovoltaic bracket manufacturers and you come to see, how to install photovoltaic bracket on flat roof.
Flat roof bracket installation method.
1、First of all, clean the roof debris, using a ruler in the roof to measure the position of the root device, place the root;
2、Use the impact drill to cement bottom drilling, hole depth according to the thickness of the bottom and bolt length resolution, bolt diameter M10. (The bottom early pre-buried bolt disposal thread on impurities);
3, the shrinkage bolt into the hole, the use of wood hammer or leather hammer and other non-metallic hammer will quietly knock the bolt into the hole, and the hole spacing of 30mm;
4, the installation of the bottom beam or base, the bottom beam hole or base hole aligned with the bolt using a wrench to tighten the nut; (according to the following way to fix other root base);
5, according to the bracket angle measurement after the column device position, the use of bolts to fix the base and the rear column;
galvanized steel tube factories
6、Fix the inclined beam, use the angle articulation and the rear pillar fixed, use the bolt to connect the inclined beam with the base;
7, fixed keel, according to the component installation hole to determine the keel installation status, keel and installation hole interval adhere to ± 100mm, the component ends of the border from the inclined beam 200-300mm, the use of shaped nuts to fix the keel on the inclined beam;
8, component installation, installation before determining the height of the component installation, the lower glass surface of the component is 300mm apart from the air, the use of side pressure block fixed components, first fixed the lower pressure block to avoid component slippage, component frame interval keel ends 20-30mm. fixed when two people need to cooperate, the use of wire pulling method or degree ruler to determine the parallelism of the entire component.
