[0055] It should be noted that, by threading the positioning screw sleeve 51 at a specified height of the suspension rod 3, the positioning screw sleeve 51 and the cushion sleeve 4 are threadedly installed at the suspension rod 3, and then the load-bearing keel 1 is fitted to the bottom surface of the cushion sleeve 4, and the suspension rod 3 passes through the load-bearing keel 1, and the fastening nut 52 is threadedly connected to the suspension rod 3, so that the load-bearing keel 1 is threadedly installed on the suspension rod 3 through the fastening mechanism 5, and forms a fitting arrangement with the cushion sleeve 4, and at this time, the threaded fastening installation process of the load-bearing keel 1 is completed;

[0056] Further as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, it is worth to explain in detail that the interior of the cushion cover 4 is provided with a hanging mechanism 6 for carrying the keel 1, wherein the hanging mechanism 6 includes a fixing rod 61, two fixing rods 61 are provided and are respectively vertically fixed to the outer surfaces of both ends of the carrying keel 1, and the inner wall of the cushion cover 4 is rotatably connected with four rotating rods 62 distributed at equal angles;

[0059] It should be noted that before the load-bearing keel 1 is installed through the fastening mechanism 5, the first hanging rod 65 and the second hanging rod 66 are respectively passed through the slide groove 64 and connected with the tensioning member 67. First, the hook 63 located near the cushion sleeve 4 is docked through the first hanging rod 65 and the second hanging rod 66, and the load-bearing keel 1 is initially hung and installed below the suspension rod 3 through the elastic force of the tensioning member 67 until it is below the two adjacent suspension rods 3. At the same time, the bottom surface of the load-bearing keel 1 is synchronously lifted up vertically until the top surface of the load-bearing keel 1 synchronously passes through the bottom end of the suspension rod 3, and then synchronously threadedly fastened through the two fastening nuts 52, thereby effectively preventing the load-bearing keel 1 from having a height deviation during fastening and installation, thereby causing the bottom surface of the load-bearing keel 1 to be uneven after fastening and installation.

[0060] After the load-bearing keel 1 is fastened and installed, the top surface of the load-bearing keel 1 will drive the rotating rod 62 to rotate upward until the first hanging rod 65 and the second hanging rod 66 are separated from the hook 63 near the cushion sleeve 4, and then the first hanging rod 65 and the second hanging rod 66 are connected to the outer hook 63 respectively through the elastic tensioning action of the tensioning member 67.

[0066] It should be noted that when installing the covering keel 2, one end of the covering keel 2 is first supported, and then the covering keel 2 is sequentially buckled into the U-shaped groove of the load-bearing keel 1, and then the second hanging rod 66 is penetrated from the covering keel 2 located in the middle at the pull rope 76, and the subsequent pull ropes 76 are penetrated in sequence.

[0070] It should be noted that the mounting strip 8 is fastened to the inner wall of the building structure before the installation of the covering keel 2, so as to support one end of the covering keel 2. After the installation of the other mounting strip 8 is completed by the covering keel 2 and the load-bearing keel 1, a support is formed for the other end of the covering keel 2. Subsequently, a plurality of ceiling panels 9 are sequentially spliced ​​and installed in the top surface grooves of the two mounting strips 8, and are threadedly fixed to the covering keel 2 by self-tapping screws, thereby completing the installation of the entire light steel keel ceiling.

[0073] It should be noted that the first hanging rod 65 and the second hanging rod 66 respectively pass through their own L-shaped sleeve rod 673. Through the elastic force of the tensioning spring, the first hanging rod 65 and the second hanging rod 66 are inserted into the hook 63, thereby forming a tensioning treatment for the first hanging rod 65 and the second hanging rod 66, thereby further improving the hanging installation stability of the load-bearing keel 1 at the suspension rod 3.
