After the decorative board is connected to the sling, the upper end of the sling is fixed to the upper part of the framework structure to realize the suspension connection of the decorative board by using the hoisting assembly. The utility model enables the decorative board to be installed one by one without being installed within the framework structure, so as to improve the assembly efficiency.

[0021] See Figure 4 , an installation plate 110 is provided on the framework structure 10. The hoisting assembly 50 includes an installation frame 510 provided on the installation plate 110. A sling connecting member 540 is slidably arranged on the installation frame 510 in the front and rear directions. The front end of the sling connecting member 540 is connected to a sling 530. A pulley 520 is rotatably arranged on the front side of the sling connecting member 540. The sling 530 is wound around the pulley 520 and extends downward. The decorative board 20 is fixedly connected to the sling 530;

[0022] A tensioning assembly 500 is provided on the installation frame 510. The rear end of the sling connecting member 540 is connected to the tensioning assembly 500. The tensioning assembly 500 is used to apply a force to the sling 530 so that the entire sling 530 is tightened to suspend the decorative board 20.

[0023] See Figure 4 , the tensioning assembly 500 includes a pull rod 550 provided at the rear end of the sling connecting member 540. A limiting member 570 is provided at one end of the pull rod 550 away from the installation frame 510. A tensioning spring 560 is sleeved on the pull rod 550 between the limiting member 570 and the installation frame 510. The tensioning spring 560 applies a backward force to the limiting member 570, and this force is transmitted to the sling 530 through the pull rod 550 and the sling connecting member 540, thereby tightening the sling 530.

[0024] See Figure 4 , a through hole 511 penetrating in the front and rear directions is provided on the installation frame 510. The sling connecting member 540 is movably inserted into the through hole 511.
