[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0027] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0028] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0029] The utility model provides a metal insulation decorative panel for building exterior walls, such as Figures 1 to 4 As shown, it includes a metal outer cover 1 and a closing plate 2 . The metal outer cover 1 is provided with a mounting groove 11 , and the mounting groove 11 is filled with a heat-insulating protective structure 3 .

[0030] In this embodiment, the metal outer cover 1 is fixedly connected to the closing plate 2, and a limiting member 21 is provided on the end face of the closing plate 2 away from the metal outer cover 1. The limiting member 21 is matched with a fixing member 22, and the fixing member 22 is provided with a limiting groove 221 for engaging with the limiting member 21. The fixing member 22 is fixedly installed on the outer wall of the building so that a gap is formed between the closing plate 2 and the outer wall of the building. In this embodiment, a fixing ear is provided on the side wall of the fixing member 22, and the fixing member 22 can be fixed to the outer wall of the building by installing screws, bolts, etc. on the fixing ear.

[0031] In this embodiment, the decorative panel can be firmly installed on the exterior wall of the building through the cooperation of the limiter 21 and the fixing member 22. The decorative panel is connected to the fixing member 22 through the limiter 21, so a gap is formed between the decorative panel and the exterior wall. The gap forms an air layer to ensure that the decorative panel is not in direct contact with the exterior wall, avoiding the formation of condensation droplets on the decorative panel or the exterior wall due to temperature differences. Air is a poor thermal conductor and its thermal conductivity is much lower than that of solid materials. Therefore, this air layer can effectively slow down the heat exchange between the exterior wall and the decorative panel, play a role in heat insulation, and further reduce the risk of condensation. The existence of the gap can allow a certain amount of thermal expansion and contraction, thereby avoiding stress concentration caused by temperature changes, reducing the risk of damage to the decorative panel due to excessive stress, and increasing the adaptability and stability of the entire structure.

[0032] In this embodiment, the gap between the closing panel 2 and the building's exterior wall is 3-5 cm wide. It should be noted that the size of the gap depends on the specific material, structure, and environmental conditions. A gap that is too large or too small can affect the performance of the overall structure. An excessively large gap can cause the decorative panel to loosen or wobble, affecting its appearance and service life. An excessively small gap may not adequately accommodate thermal expansion and contraction, increasing the risk of damage.

[0033] In this embodiment, the limiting member 21 includes a connecting portion 211 and a limiting portion 212. The limiting member 21 and the closing plate 2 are integrally formed. The connecting portion 211 and the limiting portion 212 form an L-shaped structure. The limiting portion 212 is engaged with the limiting groove 221 to increase the strength and stability of the structure while reducing the complexity of assembly, ensuring that the closing plate 2 can be accurately positioned and fixed in the correct position.

[0034] In this embodiment, a snap fastener 23 is provided on the upper side wall of the closing plate 2, and a snap fastener groove 24 that can cooperate with the snap fastener 23 is provided on the side wall of the closing plate 2 opposite to the snap fastener 23. The two adjacent decorative panels can be connected and fixed by the snap fastener 23 and the snap fastener groove 24.

[0035] In this embodiment, the snap groove 24 is configured as a right-angled through groove structure. The snap groove 24 includes two openings 241 . The two openings 241 are respectively located on the side wall of the closing plate 2 and the end surface of the closing plate 2 facing the limiting member 21 .

[0036] When the latch 23 is fully inserted into the latch groove 24 and the step surface 231 abuts against the latch groove 24, the latch 23 is firmly locked in the latch groove 24, ensuring the stability of the closure member fixed to the exterior wall of the building and ensuring that the latch 23 will not automatically exit the latch groove 24 without external force when inserted into the latch groove 24.

[0037] In this embodiment, the fasteners 23 and the fastener grooves 24 are respectively included in two groups. The two groups of fasteners 23 are respectively located on the adjacent two sides of the closing plate 2, and the two groups of fastener grooves 24 are respectively located on the adjacent two sides of the closing plate 2, so that the two adjacent decorative panels can be conveniently connected and fixed through the interlocking cooperation of the fasteners 23 and the fastener grooves 24, which can provide higher stability and firmness for the installation of the decorative panel on the exterior wall of the building.

[0038] In this embodiment, the thermal insulation and protective structure 3 comprises a heat insulation board 31, a wire mesh 32, a heat insulation board 33, and a fiber mesh 34, arranged in sequence toward the closing panel 2. The heat insulation board 31 is a thermal isolation layer with excellent thermal insulation properties, effectively preventing heat transfer, reducing indoor temperature fluctuations, and improving indoor comfort. The wire mesh 32 is primarily used to reinforce the thermal insulation and protective structure 3, improving its insulation effect and enhancing its stability. In other embodiments, the metal mesh 32 can be in various forms such as galvanized steel mesh, low-carbon steel mesh, etc. The metal mesh 32 has good tensile strength and corrosion resistance, can be tightly combined with the insulation material, and can effectively prevent the thermal insulation protection structure 3 from cracking and falling off; the insulation board 33 is the main part of the insulation structure, which is directly responsible for improving the thermal insulation performance of the building. It has excellent thermal insulation performance, reduces indoor temperature fluctuations, and improves indoor comfort. The insulation board 33 also has certain fire and moisture resistance, and can protect the structure of the building from erosion; the fiber mesh 34 mainly plays the role of enhancing the mechanical properties of the thermal insulation protection structure 3, improving the stability and corrosion resistance of the thermal insulation protection structure 3, and can significantly improve the tensile strength, compressive strength and impact resistance of the thermal insulation protection structure 3, and effectively prevent the thermal insulation protection structure 3 from being damaged by external factors. The fiber mesh 34 also has excellent corrosion resistance and fire resistance, and can adapt to various harsh environments.

[0039] In this embodiment, a fixing pin 4 is provided on the closing plate 2. The fixing pin 4 passes through the closing plate 2, the thermal insulation protection structure 3, and the mounting groove 11 in sequence and is fixedly connected to the metal outer cover 1, ensuring that a firm connection is formed between the metal outer cover 1 and the closing plate 2, ensuring that the thermal insulation protection structure 3 is stably fixed in the mounting groove 11, and ensuring the stability of the structure.

[0040] In this embodiment, a sealing gasket 5 is provided on the side wall of the metal outer cover 1. The sealing gaskets 5 between two adjacent decorative panels are pressed against each other to maintain the sealing between the two adjacent decorative panels, prevent liquid, gas or other media from penetrating from the gap, and protect the decorative panels and the exterior wall of the building from damage.
