[0017] The present invention has the following beneficial effects:

[0018] (1) The hanging parts realize the hanging between the decorative panels and the keels, so that the decorative panels can be stably installed on the keels and withstand certain gravity and external forces. At the same time, the use of adhesives not only bonds the decorative panels to the wall, but also fills the internal space of the back rib tube, increasing the reliability of the connection, playing a double fixing role, optimizing the keel structure and connection method, reducing the use of metal keels or using more economical keel materials, while simplifying the installation process and reducing labor costs.

[0019] (2) An adhesive bonded to the wall is arranged in the slot of the back rib tube and in the surrounding area of ​​the back rib tube, and the wall and the decorative panel are connected after the adhesive is cured. The adhesive is embedded in the inner space of the open square tube and forms a mechanical connection with the inner convex portion to prevent the adhesive from detaching from the open square tube, thereby improving the safety performance of the decorative panel system.

[0020] (3) By providing a mortar reinforcement layer and pre-buried steel bars or external expansion tube related structures on the wall bonded with the adhesive, the connection performance between the mortar reinforcement layer and the wall is improved, thereby improving the bonding performance between the decorative panel and the wall, especially the exterior wall of an existing building.

[0021] (4) By respectively arranging the first inclined portion and the second inclined portion and the reinforcing connection block for screwing in the self-tapping screws on the lower side of the keel, the keel does not need to be very thick and the hanging parts can be quickly fixed on the reinforcing connection block by the self-tapping screws. While ensuring the safe and reliable connection of the decorative panel, the installation efficiency of the decorative panel system is improved and the cost is reduced.

[0022] (5) A reinforced metal panel is formed by bonding a flexible reinforcing mesh layer to the back of a thin metal panel. The better softness and tensile strength of the flexible reinforcing mesh layer are utilized to greatly increase the folding strength of the reinforced metal panel. The better ductility of the flexible reinforcing mesh layer is utilized to increase the deformation resistance of the thin metal panel and the inner panel when heated at high temperatures. The larger number of mesh gaps in the flexible reinforcing mesh layer ensures that even if the adhesive between the thin metal panel and the inner panel is unevenly applied, the flatness of the thin metal panel will not be deteriorated, so that the folded edge of the reinforced metal panel can be connected and fixed with an anchor or fixed to the side of the inner panel. When the thin metal panel is heated at high temperatures, it is not easy to bulge and deform locally, thereby improving the safety and flatness of the decorative panel system of the metal finish.

[0023] (6) By setting a plurality of mounting holes on the wall and rotatably connecting the reinforcing connectors on the open square tube, the horizontal insertion portion of the reinforcing connector is rotatably connected to the open square tube and the U-shaped connection portion is embedded in the solidified filler in the mounting hole. Not only is the connection between the decorative panel and the wall more firmly made, but the horizontally fixed reinforcing connector can also play a role in supporting the decorative panel, thereby further enhancing the safety performance of the decorative panel.

The inner panel 410 can be made of fiber cement board, thermosetting board with built-in steel wire mesh, high-strength insulation board, silicon graphene insulation board, etc. The connecting piece 510 can be a bolt and nut structure or a riveted structure. In other optional embodiments, the adhesive 600 can also partially fill the internal space of the open square tube 500.

[0049] In other optional embodiments, the inner panel 410 may be a composite insulation board, which includes an intermediate insulation board and two polymer mortar layers respectively arranged on the upper and lower surfaces of the intermediate insulation board, wherein a first mesh cloth is arranged in the polymer mortar layer. The intermediate insulation board may be a thermosetting composite polystyrene foam insulation board with a built-in steel mesh, a silicon graphene insulation board, etc.

[0050] The inner panel 410 of the decorative panel is provided with a countersunk hole 411, and the back rib tube is provided with a corresponding circular hole 520, and the connector 510 is passed through the two to realize the fixed connection between the decorative panel 400 and the back rib tube. The horizontal connection part 310 of the hanging part 300 is fixed to the keel 200, and the plug-in part 320 is plugged into the slot 530 of the back rib tube to form a stable mechanical connection structure. The lower plug-in part 320 is inserted into the plug-in slot of the lower decorative panel, and the upper plug-in part 320 is inserted into the plug-in slot of the upper decorative panel. This connection structure ensures that the decorative panel is firmly fixed on the keel 200, and greatly improves the flatness between the upper and lower decorative panels. At the same time, the decorative panel is bonded to the wall 100 by the adhesive 600, and the adhesive 600 fills the internal space of the back rib tube. The adhesive force of the adhesive 600 is used to firmly bond the decorative panel to the wall 100, further enhancing the connection stability.

[0051] The finishing layer 420 is a thick metal panel, such as an aluminum plate with a thickness of 1.2-1.5 mm. In other optional embodiments, the finishing layer 420 may also be made of paint or real stone paint.

[0052] like Figure 4 , 5 As shown in FIG. 7 , a plurality of supporting shafts 550 are provided on the open square tube 500. Figure 5 From the perspective of the support shaft 550, the two ends of the support shaft 550 are fixedly connected to the two side walls of the open square tube 500, and there is a gap between the support shaft 550 and the top wall of the open square tube 500. The support shaft 550 increases the overall structural strength of the open square tube 500, enabling it to better withstand external forces. When the decorative panel is impacted or subjected to other external forces, the support shaft 550 can share part of the force, reducing the possibility of deformation or damage of the open square tube 500, thereby improving the stability and reliability of the entire decorative panel system. The support shaft 550 is embedded in the adhesive 600, making it more difficult for the adhesive 600 to separate from the open square tube 500.

[0054] When the decorative panel system is applied to an existing building wall 100, since the base layer of the existing building wall 100 is not strong, directly bonding the decorative panel to the wall 100 is not safe and reliable. Therefore, when the decorative panel system is bonded to the existing building wall 100, the base layer of the existing building wall 100 should be strengthened. Specifically, a mortar reinforcement layer 110 is provided on the surface of the wall 100, the adhesive 600 is bonded to the mortar reinforcement layer 110, a plurality of mounting holes 120 are provided on the wall 100, the mounting holes 120 are provided with embedded steel bars 130 having threaded portions, the threaded portions pass through the mortar reinforcement layer 110, a fixing nut 131 is provided on the threaded portions, a gasket 132 is provided between the fixing nut 131 and the mortar reinforcement layer 110, one end of the embedded steel bars is provided in the mounting hole 120, a filler 121 is provided in the mounting hole 120, the filler 121 can be a grouting material or a fixing glue, and a second mesh cloth is provided in the mortar reinforcement layer 110.
