Description

Technical Field

[0001] The invention relates to an aluminum single plate with a heat insulation structure. Background Art

[0002] Metal curtain walls currently primarily utilize aluminum veneer, aluminum-plastic composite panels, or aluminum honeycomb panels as their basic components, with aluminum veneer and aluminum-plastic composite panels being the most commonly used. Conventional aluminum veneer is typically formed by stamping a single layer of aluminum sheet. Other accessories are then attached to the stamped form. The finished product is then sprayed or rolled to create a paint system. The resulting product is called an aluminum veneer.

[0003] Figure 1 This is a schematic diagram of the back structure of a known aluminum veneer. Generally speaking, the front of the aluminum veneer is a decorative surface, which has high requirements for the paint system and the regularity of the geometric shape of the board surface. Therefore, the structure for fixing the aluminum veneer or installing other accessories is usually on the back of the aluminum veneer body 6, such as Figure 1 The four back flanges 4 shown in the figure are fixed to the back flanges 4 by rivets 1 with angle brackets 3, and fixed to the back side of the plate 6 by screws 7. Aluminum veneer is a lightweight panel and is mostly used for exterior walls. The aluminum veneer is fixed to the keel or other structure installed on the exterior wall by angle brackets 3. Due to the existence of cold bridges, aluminum veneer is usually not insulated. However, with the development of technology and the current increase in the demand for exterior wall insulation, some aluminum veneers are also composited with insulation materials. Collectively, they are called insulated aluminum veneer, forming part of the exterior wall insulation system, improving the overall insulation effect of the exterior wall.

[0004] Chinese patent document CN205189310U discloses an aluminum veneer panel, comprising an aluminum plate (i.e., a plate body) and angle brackets mounted on the plate. The aluminum plate is divided into two filling cavities by reinforcing ribs. Each filling cavity is provided with an aluminum pressure plate. A sliding groove for the aluminum pressure plate is provided between the reinforcing ribs and the front and rear walls of the aluminum plate. Mineral wool is filled between the aluminum pressure plate and the aluminum plate, thereby forming an insulated aluminum veneer panel. To accommodate the mineral wool filling, sufficient filling channels are required. However, the aluminum pressure plate has a relatively small area. After the mineral wool is filled, simply using the aluminum pressure plate is difficult to secure. In particular, the mineral wool is prone to falling off during transportation. Despite the inherent requirement that the mineral wool filling be performed after delivery, this non-factory filling method is inefficient and has relatively poor consistency, placing high demands on the customer. In particular, the filling requires a certain density, but aluminum veneer has low strength. Improper handling by on-site workers without factory-level assembly experience can easily lead to plastic deformation of the aluminum veneer, affecting its overall surface quality.

[0005] Chinese patent document CN207776323U discloses a heat-insulating aluminum veneer panel, which includes an aluminum veneer panel body, a side panel with corner brackets on the outside of the aluminum veneer panel body, a reinforcing rib on the inside, and a press cap on the inside surface. The aluminum veneer panel body is defined as a multi-layer structure, including a protective layer, a heat-insulating layer, a thermal insulation layer, and a baffle. The adjustment bolt that cooperates with the press cap penetrates the baffle, the thermal insulation layer, and the thermal insulation layer, and then embeds into a groove formed on the surface of the protective layer. The adjustment bolt is adapted to fit into the groove as a fixing plate. The fixing method is not specified. The current structure used for such fixing is welding. Although the welding structure is reliable, it is easy to cause deformation of the aluminum or aluminum alloy plate body, affecting the overall decorative effect. Since the reinforcing ribs are located on the back side of the aluminum veneer body, the two ends of the reinforcing ribs are fixedly connected to the side panels, which will make the aluminum veneer thicker and the side panels wider as a whole. In addition, the reinforcing ribs are fixed at both ends and suspended between the aluminum veneer body, and have no reinforcing effect on the aluminum veneer body. If additional bolts are added to create a connection at the suspended position, it will inevitably increase the amount of fasteners used and damage the strength of the aluminum veneer body (grooving is required).

[0006] Chinese patent document CN204386084U discloses an aluminum alloy decorative panel with an enclosed structure. The aluminum alloy body forms a box-like structure, filled with insulation material. Because the decorative surface of the insulation panel is relatively large, the depth of the box-like structure it fits into is relatively large, making filling with insulation material relatively difficult. If foamed insulation material is used, its filling level cannot be directly observed. Summary of the Invention

[0007] The object of the present invention is to provide a thermal insulation aluminum single plate with a relatively small overall thickness and relatively good insulation layer fixing reliability.

[0008] In an embodiment of the present invention, there is provided a thermal insulation aluminum single plate, comprising:

[0009] The plate body is a rectangular plate;

[0010] Back flange is a flange formed on the back side of the rectangular plate with a pair of opposite sides, two pairs of sides or three sides of the plate as the fold line;

[0011] Angle brackets are installed at least on the back flange;

[0012] The mounting plate is attached to the back of the board body by metal glue or welded to the back flange, covering or partially covering the back of the board body;

[0013] Bolts, with the bolt heads serving as connection ends, are mounted on the mounting plate in a matrix of rows and columns, and extend perpendicularly to the plate toward the back;

[0014] The inner insulation layer is laid on the mounting plate or the mounting plate and the exposed back of the plate body and is passed through by bolts;

[0015] The reinforcing ribs are provided with bolt holes corresponding to the rows and / or columns in the row-column matrix and corresponding to the bolts located on the corresponding rows or columns, the reinforcing ribs being fixed by the bolts and pressing the inner insulation layer;

[0016] The outer thermal insulation layer is paved on the inner thermal insulation layer and connected to the inner thermal insulation layer to cover the reinforcing ribs.

[0017] Optionally, the inner insulation layer is an asbestos layer or a rock wool layer;

[0018] The end of the reinforcing rib is welded to the back flange at the end or to the attachment located on the corresponding side of the plate body.

[0019] Optionally, the mounting plate is a block structure, and the corresponding blocks correspond to the bolts one by one;

[0020] Accordingly, the blocks are formed into patches, which are mounted on the back of the board through metal glue.

[0021] Optionally, the patch has a convex portion for positioning the reinforcing rib on a side away from the plate body;

[0022] The side where the patch is mounted to the plate is provided with a countersunk hole for accommodating the bolt head;

[0023] The hole on the patch for the bolt to pass through is a threaded hole or a light hole. If it is a light hole, the countersunk hole has a structure to prevent the bolt head from rotating, and the gap between the accessory or the bolt head and the countersunk hole wall is filled with glue.

[0024] Optionally, there is a glue layer between the surface for paving the inner thermal insulation layer and the surface on which it is paved.

[0025] Optionally, in the normal direction of the plate body, the inner insulation layer is pre-pierced with a U-shaped iron wire piece, and the two arms of the U-shaped iron wire piece are pre-reserved with a connection length after passing through the inner insulation layer;

[0026] The connection length portion of the U-shaped iron wire piece further passes through the outer insulation layer and is folded or connected to each other to form a restraining portion.

[0027] Optionally, the U-shaped iron wire piece is adapted to be equipped with a pressing plate, and the pressing plate is provided with insertion holes corresponding to the two arms of the U-shaped iron wire piece;

[0028] The pressing sheet pressed on the outer surface of the outer heat-insulating layer is pressed by the connection length portion passing through the corresponding insertion hole and then being folded over.

[0029] Optionally, the bolts are exposed from the outer surface of the outer insulation layer;

[0030] Accordingly, the outer insulation layer is pressed by connecting the exposed bolt portion through the nut and the gasket.

[0031] Optionally, the number of bolts corresponding to the back side of the plate is 6 to 8 per square meter.

[0032] Optionally, a side panel is provided at the upper edge corresponding to the installed state of the board body. The side panel is folded backwards and forms an angle of 89 degrees with the back surface of the board body.

[0033] In an embodiment of the present invention, a mounting plate is additionally installed on the back of the aluminum veneer plate body. The mounting plate and the back of the plate body are attached using metal glue or welded between the side and back flange of the mounting plate. Both of these mounting methods do not affect the decorative surface of the aluminum veneer, that is, they do not affect the apparent quality of the front of the aluminum veneer. The mounting plate can be used as a mounting base for bolts, and the reinforcing ribs can be directly fixed using bolts in some options, and the insulation layer is further divided into two layers. The inner insulation layer located in the inner layer is first pressed by the reinforcing ribs, which increases the fixing points of the inner insulation layer as a whole. Furthermore, the outer insulation layer can establish a connection with the inner insulation layer and shield the reinforcing ribs. In other words, the reinforcing ribs are actually located inside the insulation layer and do not occupy additional space in the thickness direction of the plate body, making the overall thickness of the insulating aluminum veneer relatively small. The reinforcing ribs shielded by the insulation layer can play a role in blocking large-area cold bridges, and the overall insulation effect is relatively good. The insulation layer is fixed by bolts and reinforcing ribs. The reinforcing ribs conventionally used for aluminum veneers have a relatively large area in the plane parallel to the back of the plate, that is, a relatively large pressing area, which can play a good pressing role on the inner insulation layer. The contact area between the inner and outer insulation pipes is larger, which makes it easy to form a better connection, so that the overall fixing effect of the insulation layer is better.

[0046] Refer to the instruction manual Figure 1 , is a schematic diagram of a known aluminum veneer structure. Although there are structural differences between different aluminum veneers due to different installation positions, configurations, and applicable objects, their basic structures are exactly the same in terms of structural configuration. They must include a plate body 6, and the plate body 6 is usually a rectangular plate. In the installed state, the side facing the installation base such as the wall side is the back side or can also be called the inner side or the back side, and the side opposite to the back side is the front side, the outer side or the front side, where the front side is usually a decorative surface, and is mostly a paint system.

[0047] The paint system, sometimes referred to as a paint film, generally includes a chromium coating, a primer, a topcoat, and a varnish. The number and functionality of the paint layers vary depending on the application. A backcoat is also typically applied for corrosion protection.

[0048] The paint layer needs to be sprayed or rolled after the aluminum veneer substrate is partially formed. The surface quality of the aluminum veneer substrate affects the apparent quality of the final paint layer. As a decorative panel, the apparent quality is one of its important indicators.

[0049] Since the insulation layer is prepared on the aluminum veneer after the paint system is prepared, the preparation of the insulation layer needs to avoid or minimize the impact on the paint system.

[0050] It is particularly important to note that as technology develops, the number of paint layers increases, and the total thickness of the paint system becomes relatively thicker. As is well known, the thicker the paint system, the greater its brittleness. If the plate 6 undergoes plastic or elastic deformation, it may cause the paint system to crack or fall off.

[0051] In addition, decorative panels are usually installed in an up-down manner, such as Figure 2 In the structure shown, the side of the plate body 6 where the upper plate 10 is located is its upper side. Figure 3 The sides of the plate where the back flange 4 welded to the reinforcing rib 5 is located are the left and right sides.

[0052] Figure 2 、 Figure 3 、 Figure 4 and Figure 7 This diagram generally illustrates the process of installing or preparing the insulation layer and reinforcement ribs 5 on an aluminum veneer. Aluminum veneers are generally thin, with the plate 6 typically being 3mm thick, though this thickness may vary depending on the application. If welding is used to install, for example, reinforcement ribs 5, the weldability of thin components (thickness 3mm or less is considered thin) must be considered, particularly with regard to the impact on the decorative layer. A welding current of 70A or less and a welding rod of 2.5mm or less should be used. For overhead welding, the welding current should be controlled between 50 and 55A.

[0053] If a welding connection structure is adopted between the back flange 4 and the reinforcing rib 5, the distance between the weld 13 and the plate body 6 should be not less than 5 mm to reduce the influence of welding on the paint layer.

[0054] If a welding connection structure is adopted between the back flange 4 and the reinforcing rib 5, the back flange 4 should be sprayed with anti-corrosion paint after welding, without pre-painting the paint layer.

[0055] As mentioned above, the plate body 6 of the aluminum veneer is usually a rectangular plate. Depending on the configuration, it usually has a pair of sides with back flanges 4. The back flanges 4 and the plate body 6 are usually stamped as a whole from the plate, and the back flanges 4 and the plate body 6 are bent with the edge line of the plate body 6 as the fold line.

[0056] In such Figure 10 In the structure shown, there are three back flanges 4, and Figure 9 The structure shown has two rear flanges 4 , each of which is provided with a corner bracket 3 . Figure 2 、 Figure 3 、 Figure 4 and Figure 7 The illustrated structure has three back flanges 4, with corner brackets 3 provided on the left and right back flanges 4. In some embodiments, there may be four back flanges 4, with each back flange 4, or each left and right back flange 4, or each top and bottom back flange 4, provided with a corner bracket 3. This is common knowledge in the art and will not be further elaborated here.

[0057] As for the angle code 3, although it is not a standard part, its structure is roughly the same. It is a 90-degree angle piece. A rivet hole is opened on one plate surface of the angle piece, and it is fixed to the corresponding back flange 4 by rivet 1.

[0058] The other plate surface of the corner piece is provided with a fixing hole 2 for installing the aluminum single plate on a wall frame, for example.

[0059] The fixing hole 2 can be a pair of round holes or a single elongated hole.

[0060] exist Figure 2 As can be seen in the structure shown, the bolt 11 is installed on the back of the plate body 6 through the patch 12. The patch is a preferred embodiment. In some embodiments, a strip-shaped mounting plate or an integral mounting plate can also be used for installing the bolt 11 on the plate body 6.

[0061] The patch 12 is mounted on the board 6 using metal glue. The metal glue is a glue with ethyl cyanoacrylate (ECA, also known as ethyl 2-cyano-2-acrylate) as the main component, which can be used for bonding between metals. The connection strength is comparable to welding.

[0062] The current price of metal glue is about 80 to 100 yuan per kilogram, and it can be used on a large scale in the industry.

[0063] Compared with welding, which is prone to high-temperature deformation and denaturation of welded parts, metal glue will not cause deformation or distortion of the connected parts, and plays an irreplaceable role in the connection of ultra-thin parts.

[0064] In addition, metal glue cures quickly, generally curing in about 5 seconds. Therefore, there is no need to wait for cooling before proceeding to the next step like welding. The use of metal glue can effectively improve assembly efficiency.

[0065] As for the mounting plate, it can be known from the above content that it can be a whole plate or a split plate. In the embodiment of the present invention, the split plate is preferred because a large amount of scraps will be generated in the aluminum veneer production workshop. Due to the irregular shape of the scraps, it is more suitable for small pieces. The stamping method is used to produce Figure 5 The convex portion 17 shown in FIG. 1 is further punched to form a via hole 18 and can be used as a patch 12.

[0066] The protrusion 17 and the through hole 18 can be formed in one step, and a progressive die can be used. Since in the embodiment of the present invention, the patch 12 corresponds to the bolt 11 one by one, there is no high requirement for the shape of the patch blank. Figure 2The rectangular piece shown in the figure only needs to have enough mounting area, and can be of various shapes. Therefore, almost all the scraps of aluminum veneer can be used to make the patch 12.

[0067] When making the patch 12, the leftover material is first leveled using a mold to obtain better mounting conditions.

[0068] Likewise, if Figure 8 The pressing sheet 23 shown in the figure can also be made of scraps, thereby consuming a large amount of scraps instead of treating them as waste, saving a lot of costs.

[0069] As mentioned above, the strength of the metal glue connection is comparable to that of welding. Therefore, for example, the area of ​​the patch 12 used for mounting does not need to be too large. Generally, the area of ​​each patch 12 that can be used for mounting is not less than 0.25 square centimeters to meet the requirements. Patches 12 with relatively regular shapes are easier to achieve the resultant force of the connection consistent with the axis of the locked bolt 11.

[0070] Generally, the patch 12 can be reliably fixed on the board 6 by forming several evenly distributed glue dots on the patch 12 through glue dispensing.

[0071] In particular, for relatively large individual mounting boards, multiple connection points can be formed by dispensing glue instead of gluing the entire surface.

[0072] In some embodiments, if the mounting plate is relatively large, both ends can contact with, for example, the back flange 4, and a connection can be formed between the end of the back flange 4 and the mounting plate. The connection method can adopt a welding structure, but welding is avoided as much as possible.

[0073] In the mechanical field, even edge connections can be made with metal glue. Therefore, when the end of the mounting plate comes into contact with the back flange 4, metal glue can be used for connection there.

[0074] It should also be noted that the number of bolts 11 used should not exceed 8 per square meter, taking the back area of ​​the plate 6 as a parameter. Therefore, it is preferred that the patch 12 is used to fix the bolts 11 on the back of the plate 6.

[0075] In addition, the number of bolts 11 is usually based on the back surface area of ​​the plate 6 and should not be less than 6 per square meter.

[0076] Another thing to consider is that the back area of ​​the plate 6 is usually less than 1 square meter. If the plate 6 is too small, it does not actually need to be reinforced by the reinforcing ribs 5. The back area of ​​the plate 6 reinforced with the reinforcing ribs 5 is usually not less than 0.3 square meters.

[0077] If the bolts 11 are selected, even if the plate 6 is relatively small, the number of bolts used on each plate 6 is no less than 2.

[0078] The mounting plate can fully cover the back of the plate body 6 or partially cover it, with the latter being preferred. In a more preferred embodiment, the total area of ​​the back of the plate body 6 covered by the mounting plate is no more than one tenth of the total area of ​​the back of the plate body 6, so as to reduce the total weight of the thermal insulation aluminum veneer and reduce the use of good heat conductors.

[0079] exist Figure 2 In the structure shown, ten bolts 11 form a row-column matrix, with two rows and five columns, and each row corresponds to a reinforcing rib 5. In some embodiments, the reinforcing ribs 5 can also be arranged vertically and horizontally, not limited to the vertical and horizontal arrangements. Figure 3 A single horizontal arrangement is shown in .

[0080] like Figure 6 As shown, the bolt head 20 of the bolt 11 is located on the side of the patch 12 , and the screw portion extends away from the plate body 6 and is perpendicular to the plate body 6 .

[0081] Figure 3 To clearly illustrate the relationship between the reinforcing ribs 5 and the back of the plate 6, the inner insulation layer 14 is omitted. In the preferred embodiment of the present invention, the inner insulation layer 14 is installed first, followed by the reinforcing ribs 5. In other embodiments, the reinforcing ribs 5 can be installed first, followed by the insulation layer 14. In the latter embodiment, the reinforcing ribs 5 can be welded, and then the paint layer on the back flange 4 can be prepared. In the former embodiment, the back flange 4 does not need to be painted first, and the anti-corrosion paint layer is sprayed or rolled after the back flange 4 and the reinforcing ribs 5 are connected.

[0082] based on Figure 3 It can be seen that the reinforcing rib 5 is supported and separated from the back of the plate body 6 by a certain distance, which is equivalent to the thickness of the inner thermal insulation layer 14. The thermal insulation layer is generally compressible, and in order to achieve relatively reliable installation, the reinforcing rib 5 should have a certain pre-tightening force after being fixed by the bolt 11. Relatively speaking, the thickness of the inner thermal insulation layer 14 in a loose state is greater than the distance at which the reinforcing rib 5 is supported and separated from the back of the plate body 6.

[0083] Relatively speaking, the inner insulation layer 14 is passed through by the bolts 11 . In some embodiments, after the inner insulation layer 14 is installed, the reinforcing ribs 5 are installed and fixed in place using nuts that cooperate with the bolts 11 .

[0084] Correspondingly, bolt holes are opened on the reinforcing rib 5 .

[0085] Then, the outer insulation layer is installed, such as Figure 7 As shown, the outer insulation layer is paved to a height substantially consistent with the height of the back flange 4. In some embodiments, as shown in FIG. Figure 9 As shown, the outer insulation layer can be relatively thick and higher than the height of the back flange 4. Based on the elasticity, the cold bridge effect of the back flange 4 is shielded or reduced.

[0086] The inner and outer insulation layers may have the same properties and are suitable for direct connection. In some embodiments, they may be directly bonded. For example, asbestos and rock wool may be made into blocks and may be directly bonded to each other.

[0087] Asbestos and rock wool are both inorganic insulation materials with a relatively high fire resistance level. They can be pre-made into blocks, which is conducive to the construction of internal and external insulation layers.

[0088] When using asbestos or rock wool as insulation material, you can use Figure 4 In the structure shown, the inner insulation layer 14 is prepared first, and then the reinforcing ribs 5 are installed, and the ends of the reinforcing ribs 5 can be welded to the back flange 4.

[0089] In some embodiments, if the Figure 4 The structure shown in FIG. 1 and the fireproof grade of the thermal insulation material is lower than grade A2, and the connection between the reinforcing rib 5 and the back flange 4 can adopt a metal adhesive bonding structure.

[0090] In the above embodiment, it is pointed out that the mounting plate is preferably a block structure, and the number of blocks is based on the number of bolts 11 used. The blocks correspond to the bolts 11 one by one to form the patches 12, and the patches 12 and the bolts 11 are preferably a type-locking structure.

[0091] exist Figure 5 In the structure shown in FIG6, the patch 2 is punched by a stamping process to form a convex hole. Figure 5 The protrusion 17 and the through hole 18 are shown. The through hole 18 is used for the bolt 11 to pass through, and a countersunk hole 19 is formed on the front side of the patch 12, that is, the side that is in contact with the back side of the plate 6, for accommodating the bolt head 20.

[0092] The countersunk hole 19 does not require high precision and can also be directly punched.

[0093] Since the structure formed by the mold has relatively good consistency, the supporting heights of the multiple protrusions 17 are roughly consistent, thereby meeting the positioning requirements of the reinforcing ribs 5.

[0094] The through hole 18 is preferably a smooth hole to facilitate integral molding. In some embodiments, the through hole can also be processed into a threaded hole, and the bolt 11 can be directly threadedly connected thereto.

[0095] If the through hole 18 is a light hole, the bolt head 20 needs to have an initial fixing structure. In some simple applications, the countersunk hole is directly filled with colloid to establish an initial friction mechanism. It is understandable that Figure 6The structure shown can be used as an assembly and as a spare part as a whole. Therefore, the filling colloid meets the time requirement of colloid curing and has better industrialization conditions.

[0096] In some embodiments, the bolt head 20 and the countersunk hole 19 are spot welded. The adhesion requirement between the bolt head 20 and the countersunk hole 19 is relatively low, and a single weld point formed by spot welding can meet the required adhesion requirement.

[0097] In some embodiments, elastic washers, for example, may be used to prevent rotation. In a more preferred embodiment, anti-rotation washers may be used directly.

[0098] In a preferred embodiment, in addition to being pressed by the reinforcing ribs 5, the inner insulation layer 14 is further chemically bonded, i.e., glued, to improve overall connection reliability and prevent detachment. The compression of the reinforcing ribs 5 prevents debonding between the inner insulation layer 14 and the plate 6.

[0099] The glue used to bond the inner insulation layer 14 and the plate body 6 can be a cheap conventional industrial glue, commonly known as an adhesive, preferably an acrylic adhesive and an even cheaper epoxy adhesive.

[0100] As for the aforementioned colloid used to fill the counterbore 19 and the bolt head 20, structural adhesive is used.

[0101] After the inner insulation layer 14 is glued with glue, the part of the inner insulation layer 14 that is not directly pressed by the reinforcement rib 5 is not easy to flip up. Furthermore, in the normal direction of the plate body 6, the inner insulation layer 14 is pre-pierced with a U-shaped iron wire piece, and the two arms of the U-shaped iron wire piece pass through the inner insulation layer 14 and reserve a connection length.

[0102] As for the iron wire, galvanized iron wire having a wire diameter of not more than 2 mm and not less than 0.7 mm is preferable.

[0103] The connection length needs to be sufficient for connection with the outer insulation layer, so that after the iron wire penetrates the outer insulation layer, the remaining connection length is sufficient to fix the outer insulation layer.

[0104] Correspondingly, the connection length portion of the U-shaped iron wire member 15 further passes through the outer thermal insulation layer and is folded or connected to each other to form a restraining portion, thereby fixing the outer thermal insulation layer.

[0105] Furthermore, industrial adhesive can be used to bond the inner and outer insulation layers.

[0106] exist Figure 7 In the structure shown, the U-shaped wire piece 15 is adapted to be fitted with a pressing piece 23. Figure 8 In the structure shown, the pressing plate 23 is provided with insertion holes 24 corresponding to the two arms of the U-shaped wire member.

[0107] Correspondingly, the pressing piece 23 pressed on the outer surface of the outer heat-insulating layer is pressed by the connection length portion passing through the corresponding insertion hole 24 and then folded over.

[0108] Furthermore, the bolts 11 are exposed from the outer surface of the outer insulation layer;

[0109] Accordingly, if Figure 7 As shown, the outer insulation layer is pressed against the column by connecting the nut 21 with the gasket 22 and the exposed bolt portion, thereby more reliably pressing the insulation layer.

[0110] Figure 7 In the illustrated structure, a side panel, namely, an upper panel 10, is provided corresponding to the upper edge of the panel body 6 when installed. The upper panel 10 is folded back and forms an 89-degree angle with the back of the panel body. In the installed state, the upper panel 10 bears pressure and is approximately perpendicular to the panel body 6.

[0111] The upper side plate 10 is also provided with a corner code 3 so that the thermal insulation aluminum single plate can be reliably assembled on the decorated object.

[0112] Figures 9 to 11 The right-side structural schematic diagram of three types of thermal insulation aluminum veneers is shown. For different applications, the thermal insulation aluminum veneer can produce a variety of structural deformations. Technicians in this field can adapt to different application objects and adopt different structural forms. If within the basic concept of the present invention, simple changes to the relevant structures should fall within the scope of protection of the present invention.
