How to install the ceiling lamp in six steps?

A, according to the horizontal line of floor elevation, vertically measure the ceiling design elevation with a ruler, play the keel position line on the roof, and play the ceiling elevation horizontal line on the wall.

Second, install the main keel suspender ceiling. Second, after playing the ceiling elevation horizontal line and the main keel position line, determine the derrick head elevation. According to the position of the main keel and the hanging distance, the bolt-free end of the suspender is fixed under the floor with an expansion bolt; 6m steel bar (8mm flat steel) for suspenders.

Third, install the main keel ceiling. Step 3, install the hanger nut, mark the hanger in advance on the main keel, thread the hanger into the corresponding hanger bolt according to the position of the step line, screw on the nut, connect the main keel, install the connector, adjust the elevation and straightness of the stay wire, install additional main keel at the hole, and set the connection.

Fourth, install the secondary keel ceiling. Step 4, according to the played sub-keel step line, put the sub-keel triangle pendant, use wooden keel, and arrange the sub-keel spacing by 600mm；; According to the distance between the main keels specified in the design, the secondary keels are hung on the main keels through triangular pendants; When the length of the secondary keel needs to be extended by more than one, use the secondary keel connector to connect the secondary keel while hanging, and straighten and fix it.

5. The specification of the aluminum bar on the installation side is 25mm*25mm, and the installation elevation of the ceiling requires that the aluminum bar on the installation side be fixed around the wall with cement nails.

6. Install the aluminum gusset plate When installing the aluminum gusset plate of the ceiling, gently press it along the flanging position sequence, then completely clamp both sides of the square plate into the secondary keel, and then push it tightly. Barbaric loading and unloading is strictly prohibited; Clamp and straighten the edge aluminum strip and fix the edge aluminum plate. According to the design requirements, the ceiling of this project adopts 600mm*600mm perforated aluminum gusset plate. Installation of lamps and vents The last step of ceiling installation is to arrange lamps and vents according to the ceiling layout; When installing aluminum gusset plate, make holes according to the size of lamps and vents, and install lamps and vents.
