[0063] S3: Connection point reinforcement: The connection plate is placed between the main keel and the secondary keel, and the clamping plate is rotated to clamp the main keel for reinforcement;

[0064] S4: Decorative panel assembly: Adjacent wiring rings are connected by thin steel wires, the top of the rotating column is embedded in the slide groove, and the decorative panels are spliced. After the splicing is neat, the rotating piece is rotated.

[0065] According to the above technical solution, in step S2, when the internal threaded tube is rotated, the laser pen laser passes through the center of the target circle to complete the leveling, and then the horizontal column and the laser pen are removed to complete the leveling of multiple main keels in turn.

[0066] According to the above technical solution, in step S3, the bottom end of the limiting stud is vertically embedded in the anti-slip groove, and the connecting plate always remains in a horizontal state.
