and drawing all the skylights into a three-dimensional model in the revit according to the gradient of the metal roof, calculating all support variables, marking the support variables one by one, and hoisting the whole roof skylight. And hoisting and temporarily fixing the welded skylight above the purline according to the site of the on-site measurement pay-off, retesting whether the skylight is positioned at the same elevation and the same horizontal plane by using a total station according to the requirements of the gradient and the elevation of the metal roof in a deepened drawing, and completely fixing the skylight and the metal roof purline after the skylight is completely adjusted in place.
S7, closing the side edges of the skylight;
the side edge of the skylight adopts an aluminum-magnesium-manganese plate seamless welding method, and an angle grinder is used for grinding the aluminum alloy finish paint at the welding part before welding so as to carry out welding operation. Preheating for 3-5 seconds at the position where the weldment starts after the electric arc is ignited, and adding an aluminum welding rod after a molten pool is formed. During welding, the welding rod welding gun has proper angle and the welding rod is fed uniformly. The welding gun moves forward stably, swings left and right slightly slowly at two sides, and is faster in the middle. And (3) slowly guiding the electric arc to one side of the groove during arc closing, and not generating a shrinkage hole, wherein welding can be performed after the shrinkage hole is polished completely if the shrinkage hole is generated. In the welding process, the waterproof coiled material needs to be cut to the welding edge by more than 50mm, and before the skylight is closed up and welded, the welding area needs to be covered with a soaked asbestos cloth or an aluminum heat insulation plate to prevent the structural layer from being ignited in the welding construction process.
