[0022] (3) By extending the flexible reinforcing mesh layer on both sides in the width direction and / or length direction to form a mesh extension, and flipping the mesh extensions on both sides downward and bonding them to the lower part of the non-metallic panel, the thin metal panel can still be fixed on the non-metallic panel when the adhesive between the thin metal panel and the non-metallic panel fails and falls off, which further improves the safety performance of the thin metal panel decorative panel.

[0023] (4) When the non-metallic panel uses a reinforced insulation board, the middle insulation board is sandwiched in the middle by setting a fixed long pad and a connecting plate on both sides of the middle insulation board. The good rigidity of the long pad and the connecting plate ensures that the flatness of the large-sized reinforced insulation board and the thin metal panel is still good after being combined, thus ensuring the aesthetic performance of the thin metal panel decorative board.

[0038] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0039] Example 1

[0040] This embodiment provides a thin metal panel 100 decorative plate, such as Figure 1 As shown, from top to bottom, the structure includes a thin metal panel 100, a reinforcing adhesive layer 200, a flexible reinforcing mesh layer 300, a first adhesive layer 400, and a non-metallic panel 500. The thin metal panel 100 is bonded to the flexible reinforcing mesh layer 300 via the reinforcing adhesive layer 200, and the flexible reinforcing mesh layer 300 is bonded to the non-metallic panel 500 via the first adhesive layer 400. The reinforcing adhesive layer 200 is a hot-melt adhesive film, which can be a polymer film, and the bonding is achieved using a hot-melt bonding process. The first adhesive layer 400 can be made of polyurethane adhesive. The thin metal panel 100 can be made of an aluminum plate with a thickness of 0.3mm-1.2mm. The flexible reinforcing mesh layer 300 can be made of fiberglass mesh, polyester fiber mesh, wire mesh, or carbon fiber mesh, etc. In other optional embodiments, the reinforcing adhesive layer 200 can also be made of the same material as the first adhesive layer 400.

[0041] like Figure 2As shown, the non-metallic panel 500 is a composite insulation board, which includes an intermediate insulation board 510 and polymer mortar layers 520 disposed on the upper and lower surfaces of the intermediate insulation board 510. The polymer mortar layers 520 contain a mesh fabric 521. The polymer mortar layers 520 on both sides of the intermediate insulation board 510 ensure good flatness of the composite insulation board. The intermediate insulation board 510 can be a thermosetting composite polystyrene foam insulation board, a graphene insulation board, a polyurethane board, a polystyrene board, an aerogel board, or a vacuum insulation board, etc. In other optional embodiments, the non-metallic panel 500 can also be a cement mortar layer with wire mesh, a fiber cement board, an insulation board with built-in steel wire mesh, a calcium silicate board, a glazed foamed ceramic insulation board, or a foamed ceramic insulation board. The upper and lower positions in this embodiment are referenced. Figure 1 Perspective, however, is not limited in practical application.

[0042] Example 2

[0043] The thin metal panel 100 and the flexible reinforced mesh layer 300 in Embodiment 1 do not have folded edges 110, while in this embodiment both have folded edges 110.

[0044] Specifically, such as Figure 3 As shown, the thin metal panel 100 is bonded to the flexible reinforcing mesh layer 300 to form a reinforced metal panel. The reinforced metal panel has two folded edges 110 in the width and / or length directions, and each folded edge 110 has at least two first insertion holes 111. The first insertion holes 111 are connected to anchors. Because the flexible reinforcing mesh layer 300 has good tensile strength, after it is bonded to the thin metal panel 100, when the first insertion holes 111 on the folded edges 110 are pulled by the anchors inserted into the holes, the thin metal panel 100 and the flexible reinforcing mesh layer 300 work together to resist the tensile force transmitted by the anchors. Compared with the single thin metal panel 100, the connection performance between the folded edges 110 and the anchors is greatly improved.

[0045] The other structures in this embodiment are the same as in Embodiment 1.

[0046] Example 3

[0047] In Embodiment 2, the folded edge 110 is connected to the anchor, and in this embodiment, the folded edge 110 is fixedly connected to the non-metallic panel 500.

[0048] Specifically, such as Figure 4As shown, the folded edge 110 is fixedly connected to the side of the non-metallic panel 500. Specifically, the thin metal panel 100 is bonded to the flexible reinforcing mesh layer 300 to form a reinforced metal panel. The reinforced metal panel has two folded edges 110 in the width and / or length directions. Each folded edge 110 has at least two connecting holes, and the folded edge 110 is fixedly connected to the non-metallic panel 500 by self-tapping screws 112 passing through the connecting holes. This enhances the connection performance between the reinforced metal panel and the non-metallic panel 500. The folded edge can also be fixedly connected to the non-metallic panel in other ways, such as by opening a slot on the side of the non-metallic panel and inserting an L-shaped connector through the connecting hole of the folded edge into the slot.

[0049] The other structures in this embodiment are the same as in Embodiment 2.

[0050] Example 4

[0051] The flexible reinforcing mesh layer 300 in Embodiment 1 does not have a mesh extension 310, while the flexible reinforcing mesh layer 300 in this embodiment has a mesh extension 310.

[0052] like Figure 5 As shown, the flexible reinforcing mesh layer 300 extends to form mesh extensions 310 on both sides in the width and / or length directions. The mesh extensions 310 on both sides are respectively flipped downwards to the lower part of the non-metallic panel 500 and bonded to the lower part of the non-metallic panel 500. Utilizing the good tensile strength of the flexible reinforcing mesh layer 300, even if the first adhesive layer 400 between the thin metal panel 100 and the non-metallic panel 500 fails and detaches, it can still be fixed to the non-metallic panel 500 by the flipped mesh extensions 310.

[0053] Furthermore, such as Figure 6 As shown, the non-metallic panel 500 has an inner insulation board 600 at its lower part, and the inner insulation board 600 is bonded to the non-metallic panel 500 by a second adhesive layer 610. The inner insulation board 600 can be a thermosetting composite polystyrene foam insulation board, a graphene insulation board, a polyurethane board, a polystyrene board, an aerogel board, or a vacuum insulation board, etc. In other optional embodiments, the decorative panel with the mesh extension 310 may not have an inner insulation board 600.

[0054] The other structures in this embodiment are the same as in Embodiment 1.

[0062] The other structures in this embodiment are the same as in Embodiment 5.

[0063] Example 7

[0064] This embodiment adds a dry-hanging structure to the embodiment four, which does not have an internal insulation board 600, so that the decorative board can be used as a panel in the dry-hanging system.

[0065] Specifically, such as Figure 9 , 10 As shown, the non-metallic panel 500 has several countersunk holes 580 penetrating through it. The lower part of the non-metallic panel 500 has multiple adapters 700 with connecting through holes, each corresponding to a countersunk hole 580. The adapters 700 and countersunk holes 580 are fixedly connected by riveting members 710. After the riveting members 710 are installed, the countersunk holes 580 are filled with filler 720. The adapters 700 have first slots at both ends, which engage with connectors on the wall joists to achieve a dry-hanging effect. In other optional embodiments, the riveting members 710 can be replaced with bolts.

[0066] In other alternative embodiments, the adapter 700 in this embodiment can be replaced with a backing rib with inclined ends. The backing rib has long slots and through holes at both ends, so that the decorative panel can be dry-hung on the wall keel.

[0067] The other structures in this embodiment are the same as in Embodiment 4.

[0068] Example 8

[0069] like Figure 11 As shown, the non-metallic panel 500 has at least two grooves 590 on each of its opposite sides. (Reference) Figure 11 The viewing angle can be either the left or right sides. In other alternative embodiments, the opposite sides can also be the front or back sides.

[0070] Furthermore, such as Figure 11 As shown, an inner insulation board 600 is provided at the lower part of the non-metallic panel 500, and the inner insulation board 600 is bonded to the non-metallic panel 500 through a second adhesive layer 610. The inner insulation board 600 can be made of thermosetting composite polystyrene foam insulation board, graphene insulation board, polyurethane board, polystyrene board, aerogel board, or vacuum insulation board, etc.

[0071] The other structures in this embodiment are the same as in Embodiment 1.

[0072] Example 9

[0073] This embodiment adds a back reinforcement structure to the original embodiment 4, which does not have an internal insulation board 600. This allows the decorative panel to be used as a panel in a dry-hanging system or an adhesive-anchored type insulation decorative panel system. This system can be mainly used for the repair and renovation of existing building walls without the need for removal. The non-metallic panel 500 with back reinforcement square tubes is firmly fixed to the keel or wall surface, so that even if there are local hollow areas on the wall surface, it will not fall off, thus ensuring the safety of the existing building walls.

[0074] Specifically, such as Figure 12 , 13 As shown, a plurality of countersunk holes 580 penetrating the non-metallic panel 500 are formed on the non-metallic panel 500. At least two back ribs are provided at the lower part of the non-metallic panel 500. Each back rib is an open square tube 800 with a second slot 850 and multiple round holes corresponding to the positions of the countersunk holes 580 on the non-metallic panel 500. The open square tube 800 and the non-metallic panel 500 are fixedly connected by a connector 810 passing through the countersunk holes 580 and the round holes. The connector 810 can be a bolt and nut structure or a riveting structure. The opening of the open square tube 800 has an inwardly protruding inner protrusion 820. Outwardly protruding outer protrusions 830 can also be provided on both sides of the open square tube 800. Multiple supporting shafts 840 can also be provided on the open square tube 800.

[0075] In this embodiment, when the non-metallic panel 500 is used in the dry-hanging system, the second slot 850 of the open square tube 800 can be connected and fixed with the plug-in component in the dry-hanging system, so that the non-metallic panel 500 is fixed on the keel of the dry-hanging system.

[0076] When the non-metallic panel 500 is used in the thermal insulation decorative panel system, the second slot 850 of the open square tube 800 is inserted and fixed with the connector in the thermal insulation decorative panel system. On the other hand, adhesive is applied inside and around the open square tube 800 to bond it to the wall. This avoids the defect that the surface of the non-metallic panel 500 cannot be firmly bonded to the wall due to poor adhesion performance. At the same time, it improves the structural strength of the back reinforcement square tube and realizes the bonding and anchoring of the non-metallic panel 500 to the wall.
