and (4) SS003: the overall length of the suspension assembly (2) is adjusted according to the height of a suspended ceiling, the telescopic adjusting column (211) is squeezed inwards at the moment, the telescopic adjusting column (211) is contracted inwards, then the vertical guide column (210) can be moved up and down, after the vertical guide column (210) is moved to a proper position, the telescopic adjusting column (211) is loosened, the telescopic adjusting column (211) can be popped out at the moment and is inserted into the adjusting hole (209) with the corresponding height, and the overall length of the suspension assembly (2) can be adjusted at the moment, and the suspended ceiling is better in effect by arranging the suspension assembly (2) and adjusting the overall length of the suspension assembly (2) according to the requirement;

SS004: screwing down a limiting nut (214) from the outer side of the threaded column (213), aligning the threaded column (213) with the circular through hole (302), inserting the threaded column (213) into the circular through hole (302), and screwing the limiting nut (214) onto the threaded column (213), so that the transverse hoisting assembly (3) is limited, and the transverse hoisting assembly (3) is installed;

SS005: aligning a positioning groove (402) on the light steel keel (4) with a positioning block (308) to enable the light steel keel (4) to be clamped between the two clamping pieces, and inserting one end of the hook-shaped through plate (304) far away from the square end plate (305) into the side hole (401) at the moment to finish the installation of the light steel keel (4);

SS006: the two adjacent decoration components (5) are mutually clamped, and then the gypsum board (501) is fixed on the light steel keel (4) through self-tapping screws (506).
