step 3, bar roof board construction: the galvanized iron plate and the steel bar truss are welded into a whole outside a construction site in advance, the steel bar truss iron plate is hoisted onto a secondary steel beam by adopting an automobile crane or a tower crane of the construction site, a U-shaped groove steel is hoisted and placed above the secondary steel beam after moving into position, the galvanized iron plate, the U-shaped channel steel and the secondary steel beam are welded and fixed by adopting a welding gun and a bolt, and the side edge of the U-shaped groove steel is welded and connected with the secondary steel beam by adopting a fillet weld to form a concrete pouring cavity and a pouring surface;
step 4, concrete pouring of the strip roof board: binding a longitudinal and transverse reinforcing steel bar net above the galvanized iron plate according to the design drawing requirements, pouring concrete in the U-shaped channel steel cavity and above the galvanized iron plate after the binding is completed to form a strip-shaped light collecting belt, and placing an embedded iron plate at the top of the U-shaped channel steel before pouring the concrete for later welding and fixing a vertical keel and an oblique keel;
step 5, pouring peripheral parapet walls: erecting a template and pouring parapet concrete on the periphery of the skylight according to the parapet shape, wherein the transverse parapet retaining wall is in a zigzag shape, the middle lower part of the parapet is provided with an outward-overhanging drip line, and the top of the parapet and the top of the strip-shaped lighting strip are welded with edge-sealing aluminum plates;
and 6, sequentially installing a skylight keel, daylighting glass, an electric opening fan and a transition aluminum plate.
9. The construction method for the roof lighting skylight with the electric smoke exhaust fan, which is disclosed by claim 8, is characterized in that: and (2) hoisting the main steel girder and then hoisting the secondary steel girder in the hoisting sequence of the steel girder in the step (2), so as to ensure that the upper surface and the lower surface of the main steel girder and the lower surface of the secondary steel girder are flush.
