In the specific implementation process, as Figure 3 shown, the sealing layer 80 is composed of a foam strip 81 and a sealant 82.

[0040] Furthermore, as Figure 3 、 Figure 4 shown, the inner surface of the upper slot 50 is provided with an upper slot cushion layer 51 (for example: a rubber layer) to enhance the fitting effect. Of course, the inner surface of the upper slot 50 may not be provided with the upper slot cushion layer 51.

[0041] Furthermore, as Figure 3 、 Figure 4 shown, the inner surface of the lower slot 60 is provided with a lower slot cushion layer 61 (for example: a rubber layer) to enhance the fitting effect. Of course, the inner surface of the lower slot 60 may not be provided with the lower slot cushion layer 61.

[0042] Furthermore, as Figures 1 to 3 shown, the upper hanging part 41 is locked and fixed to the cross beam 22 through a bolt and nut assembly 90, which is convenient for assembly.

[0043] As Figure 1 shown, the gap between two adjacent left and right curtain wall panels 30 can also be sealed by a foam strip and a sealant.

[0044] For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
