the initial aluminum plate ceiling main hollow drum is fixed: the initial keel is firmly fixed on the section steel conversion layer support, nuts on the hanging pieces are adjusted to enable the initial keel to be tightly propped against the conversion layer support, and the inclined keels are arranged at the longitudinal and transverse main keels for reinforcement, so that the light steel main keels are fixed in place and do not move, the fixed distance is not more than 2m, and a firm keel framework is formed;

sequentially installing other main light steel keels by taking the keel fixedly and firmly fixed by the starting plate as a reference, installing 5-6 main light steel keels longitudinally and transversely, and checking by contrasting the positioning line to see whether the main light steel keels are aligned with the nylon line or not; after alignment, installing the side keels; before the light steel secondary keel is installed, marking the position of a ceiling aluminum plate installation starting plate on the light steel primary keel, fixing the starting plate on the secondary keel by adopting a dovetail wire, forming an initial aluminum plate installation unit after the initial aluminum plate installation unit is adjusted in place, and installing other aluminum plates by taking the initial aluminum plate installation unit as a reference block; the aluminum plates are sequentially installed at two ends, the secondary keel is only required to be hung on the main keel during installation, the lapping type aluminum plate is hung on the light steel secondary keel, the lapping type aluminum plate and the aluminum plate are connected through the clamping piece, and the gaps are sealed by the sealing shockproof glue;

when an aluminum plate with openings such as lamp holes, fire-fighting spray holes, air conditioner air outlets and broadcasting is installed, related professionals are required to be matched with ceiling operators to fix terminal equipment in place in time, if the equipment cannot be fixed in time, power lines, network cables, electric wires, signal lines and the like are required to be led out from the holes of the aluminum plate in time, and BIM drawings are compared to realize accurate leading-out;

the aluminum plate adopts the font fossil fragments card to go into on the main joist during the installation, adopts joint spare fastening between aluminum plate and the aluminum plate, plays the effect of accurate location and locking.
