What are the steps of ceiling technology in decoration engineering?

The process steps of the ceiling of the decoration project: bounce the horizontal elevation line of the ceiling → finely draw the grid lines of the keel → install the pipeline facilities → install the suspenders of the main keel → install the secondary keel → install the gypsum board (set cutting process, the gypsum board is upside down) → brush the antirust paint → install the battens (anti-cracking corner edges) → install the gypsum line.

1, play the ceiling elevation horizontal line:

According to the floor elevation horizontal line, measure the ceiling elevation vertically with a ruler, and play the ceiling elevation horizontal line around the walls and columns.

2, draw the keel step line:

According to the design requirements, arrange the spacing between the main keel and the secondary keel, and draw the keel step line on the level line of the played ceiling elevation.

3, install the main keel:

After installing the main keel boom, play the ceiling elevation horizontal line and the keel grading position line, and determine the elevation of the lower end of the boom according to the position of the main keel and the hanging distance;

One end of the suspender without bolt thread is welded and fixed with the embedded steel bar in the floor (expansion bolt can be used when the steel bar is not embedded), and the welded part is painted with antirust paint.

4, hanging keel

According to the secondary keel spacing specified in the design, hang the secondary keel on the main keel with a hanger. When the design is not required, the general spacing is 500 _ ~ 600 _. ?

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.

Extended data:

Design requirements of suspended ceiling:

(1) Pipes and devices used for shielding structural members and various equipment.

② For the ceiling of a room with acoustic requirements, the surface shape and material should be considered according to the acoustic quality requirements.

(3) Ceiling is an important part of interior decoration and should be considered in combination with interior design. All kinds of lamps and air conditioning outlets installed on the ceiling should become an organic whole of ceiling decoration.

(4) It is convenient to maintain all kinds of equipment and pipes hidden in the ceiling.

⑤ The suspended ceiling should be convenient for industrial construction and try to avoid wet operation.
