Installation steps of ordinary decoration ceiling

That is to say, the production of suspended ceiling in ordinary decoration, the process is as follows: grassroots elastic line-installing suspenders-installing main keels-installing side keels-installing secondary keels-installing aluminum alloy square plates.

Weak line

According to the floor elevation horizontal line, according to the design elevation, pull the ceiling elevation horizontal line along the surrounding walls, and find out the center point of the room. Along the ceiling elevation horizontal line, draw the keel slope position line on the wall with the center point of the room as the center.

Install boom

After playing the ceiling elevation horizontal line and keel position line, determine the elevation of the lower end of the boom, install the pretreated boom, and fix the boom on the ceiling with an expansion bolt with a diameter of 8. The suspenders are made of round steel with a diameter of 8, and the spacing between suspenders is controlled at 1200? L range.

Install the main keel

The main keel generally adopts C38 light steel keel, and the spacing is controlled at 1200? L range. During installation, the hanger matched with the main keel is used to connect with the suspender.

Installing side keel

According to the requirement of ceiling clear height, 25×25 is fixed with cement nails around the wall. L paint keel, cement nail spacing is not more than 300? l .

Installing secondary keel

According to the specifications and dimensions of the aluminum gusset plate, install the secondary keel matched with the plate, and hang the secondary keel on the main keel through the hanger. When the length of the secondary keel needs to be extended by more than one, while hanging the secondary keel, connect the opposite ends with the secondary keel connector, straighten it first and then fix it.

Installing aluminum alloy square plate

When installing the aluminum gusset plate, pull a datum line perpendicular to the direction of the secondary keel in the middle position of the assembly area, and align it to both sides for installation. When installing, handle it with care, press the two sides of the square plate lightly according to the flanging position sequence, and then push it tightly after clamping into the keel.
