Technical Field

[0002] Currently, there are many types of integrated thermal insulation and decorative panels on the market. According to the surface finish, common products include two main categories: calcium silicate board finish and metal plate finish. Typically, integrated thermal insulation and decorative panels are composite boards, with their surface layers mainly consisting of a calcium silicate board finish and a metal plate finish. When used as the exterior finish of high-rise buildings, the calcium silicate board finish is prone to cracking due to wind pressure, environmental corrosion, earthquakes, and other factors, leading to leaks and potential detachment. While the metal plate finish has excellent crack resistance, it is severely deformed by environmental factors and is prone to detachment from the internal adhesive layer. Furthermore, the high cost of metal plates, as a decorative panel, increases the overall price of the panel, hindering the widespread application of integrated thermal insulation and decorative panels.

[0041] This application discloses a metal-faced insulation board, a metal-faced insulation assembly, and its installation process. In this metal-faced insulation board, a metal-faced panel, a faceted backing board, an insulation layer, and the insulation backing board are layered. The insulation backing board is attached to the outer wall of the building using an adhesive to bond the metal-faced insulation board to the wall. The metal-faced panel, placed on the outside of the faceted backing board, ensures a smooth and flat outer surface of the metal-faced insulation board, improving its compressive strength and facilitating the application of secondary decorative materials. Simultaneously, the faceted backing board compensates for the easily deformable nature of the metal-faced panel, further increasing the overall rigidity of the metal-faced insulation board. The bonding between the insulation backing board and the adhesive ensures the stability of the metal-faced insulation board's adhesion, allowing it to adhere stably to the outer wall of the building, preventing cracking and guaranteeing its performance.

[0042] Thus, the metal-faced insulation board, composed of a metal facing panel, a facing backing board, an insulation layer, and another insulation backing board, ensures the compressive strength of the metal-faced insulation board, facilitates the construction of secondary decorative materials, and the facing backing board supports the metal facing panel, improving the overall rigidity of the metal-faced insulation board and preventing cracking and detachment, thereby ensuring the performance of the metal facing panel. Furthermore, the metal-faced insulation board has a multi-layered composite structure, resulting in low cost and easy application.

[0043] In this metal-clad insulation assembly, fixed corner brackets are used to connect to the metal cladding panels of the insulation board. Anchors are inserted through the fixed corner brackets and installed into the building wall to fix the metal-clad insulation board to the building wall. In this way, the metal-clad insulation board is fixed to the building wall through the cooperation of the anchors and fixed corner brackets. Simultaneously, the metal-clad insulation board is also glued to the outer wall of the building wall using adhesive. This combination of bonding and anchoring reliably fixes the metal-clad insulation board to the outer wall of the building wall, preventing cracking of the metal-clad insulation assembly and ensuring its performance.

[0056] Understandably, there are many types of integrated insulation and decorative panels on the market. Common products, categorized by surface finish, include calcium silicate board finishes and metal panel finishes. Typically, integrated insulation and decorative panels are composite boards, with their surface layers mainly consisting of a calcium silicate board finish and a metal panel finish. When used as the exterior finish of high-rise buildings, the calcium silicate board finish is prone to cracking due to wind pressure, environmental corrosion, earthquakes, and other factors, leading to leaks and potential detachment. While the metal panel finish has excellent crack resistance, it is severely affected by environmental factors and deforms significantly, making it prone to detachment from the internal adhesive layer. Furthermore, the high cost of metal panels, as a decorative panel, increases the overall price of the panel, hindering the widespread application of integrated insulation and decorative panels.

[0057] For this purpose, please refer to Figure 1 and Figure 2 This application provides a metal-finished insulation board 100, which is used in a metal-finished insulation assembly 10. Figure 1This is a partial cross-sectional view of a metal-finished thermal insulation assembly 10 according to an embodiment of this application. Figure 2 for Figure 1 The diagram shows a metal-clad insulation panel 100 in the metal-clad insulation assembly 10. The metal-clad insulation assembly 10 is installed on the outer wall of the building wall 70, serving both insulation and decorative purposes.

[0058] To better illustrate the structure of the metal-clad insulation panel 100, the structure of the metal-clad insulation assembly 10 is briefly described here. The metal-clad insulation assembly 10 includes multiple metal-clad insulation panels 100 of this application, multiple anchors 200, and multiple fixing brackets 300. The multiple metal-clad insulation panels 100 are pasted in rows and columns on the outer wall of the building wall 70. There are gaps between adjacent metal-clad insulation panels 100. At least two fixing brackets 300 are provided between two adjacent metal-clad insulation panels 100. The anchors 200 are installed in the building wall 70 through at least one fixing bracket 300 to further fix the metal-clad insulation panels 100 to the outer wall of the building wall 70.

[0059] Thus, the metal-faced insulation board 100 is fixed to the outer wall of the building wall 70 by adhesive and anchoring methods, ensuring reliable fixation. This metal-faced insulation board 100 possesses high compressive strength and structural rigidity, allowing it to stably adhere to the outer wall of the building wall 70, preventing cracking and guaranteeing its performance. The specific structure of the metal-faced insulation board 100 in some embodiments is described below.

[0060] See Figure 1 and Figure 2 In one embodiment, the metal-clad insulation board 100 includes a metal-clad panel 110, a clad backing panel 120, an insulation layer 130, and an insulation backing panel 140. The clad backing panel 120 is disposed on the surface of the metal-clad panel 110. The insulation layer 130 is disposed on the surface of the clad backing panel 120 opposite to the surface of the metal-clad panel 110. The insulation backing panel 140 is disposed on the surface of the insulation layer 130 opposite to the surface of the clad backing panel 120, and is adhered to the outer wall of the building wall 70 by an adhesive 400.

[0061] The metal decorative panel 110, the decorative backing board 120, the insulation layer 130, and the insulation backing board 140 are stacked, with the insulation backing board 140 being the innermost layer. The insulation layer 130 is disposed on the outer surface of the insulation backing board 140, the decorative backing board 120 is disposed on the outer surface of the insulation layer 130, and the metal decorative panel 110 is disposed on the outer surface of the decorative backing board 120. That is, the insulation layer 130 is disposed between the insulation backing board 140 and the decorative backing board 120, and the decorative backing board 120 is disposed between the insulation layer 130 and the metal decorative panel 110.

[0062] When the metal-faced insulation panel 100 is installed on the outer wall of the building wall 70, the insulation backing panel 140 is adhered to the outer wall of the building wall 70. The insulation backing panel 140, the insulation layer 130, the decorative backing panel 120, and the metal-faced panel 110 are stacked sequentially from the direction away from the building wall 70. In this way, the metal-faced panel 110 can serve as the outer wall surface of the building wall 70, making the outer surface of the building wall 70 smooth and flat, thus playing a decorative role.

[0063] Furthermore, after the decorative backing board 120 is disposed between the insulation layer 130 and the metal decorative panel 110, the decorative backing board 120 can reinforce the easily deformable nature of the metal decorative panel 110, further increasing the overall rigidity of the metal decorative insulation board 100. At the same time, after the insulation layer 130 is disposed between the insulation backing board 140 and the decorative backing board 120, the insulation layer 130 can play a role in heat preservation, so that the metal decorative insulation board 100 has a heat preservation function, thereby providing heat preservation for the building wall 70.

[0064] Understandably, the metal-faced insulation board 100 is typically initially fixed to the outer wall of the building wall 70 by adhesive bonding. When the metal-faced insulation board 100 is adhered to the outer wall of the building wall 70, an adhesive 400 is usually applied to the surface of the insulation backing board 140, allowing the insulation backing board 140 to be bonded to the outer wall of the building wall 70 via the adhesive 400, thereby bonding the metal-faced insulation board 100 to the outer wall of the building wall 70. Optionally, the adhesive 400 may be adhesive mortar, etc.

[0065] Meanwhile, the insulation backing board 140 is located on the side of the insulation layer 130 away from the decorative backing board 120. The metal decorative insulation board 100 adheres to the outer wall of the building wall 70 through the insulation backing board 140, avoiding direct contact between the insulation layer 130 and the outer wall of the building wall 70, and also avoiding contact between the adhesive 400 and the insulation layer 130, ensuring the adhesion between the metal decorative insulation board 100 and the outer wall of the building wall 70, and improving the stability of the adhesion of the metal decorative insulation board 100.

[0066] The metal-faced insulation board 100 in the above embodiment adopts a combination of a metal-faced panel 110, a faceted backing board 120, an insulation layer 130, and an insulation backing board 140. This combination ensures the compressive strength of the metal-faced insulation board 100, facilitates the construction of secondary decorative materials, and the faceted backing board 120 supports the metal-faced panel 110, improving the overall rigidity of the metal-faced insulation board 100 and preventing the metal-faced panel 110 from cracking or falling off, thus ensuring the performance of the metal-faced panel 110. Furthermore, the metal-faced insulation board 100 has a multi-layered composite structure, resulting in low cost and ease of widespread application.

[0067] Typically, the metal-clad insulation board 100 is fixed to the building wall 70 by adhesive bonding and anchoring. Adhesive bonding increases the contact area between the metal-clad insulation board 100 and the outer wall of the building wall 70, achieving initial fixation between the metal-clad insulation board 100 and the building wall 70. At the same time, anchoring increases the number of anchoring points between the metal-clad insulation board 100 and the building wall 70, improving the reliability of the connection between the metal-clad insulation board 100 and the building wall 70, and preventing the metal-clad insulation board 100 from falling off the building wall 70.

[0068] Optionally, the metal decorative panel 110, the decorative backing board 120, the insulation layer 130, and the insulation backing board 140 are bonded and fixed together. In this way, the metal decorative panel 110, the decorative backing board 120, the insulation layer 130, and the insulation backing board 140 can be reliably fixed together to form an integral metal decorative insulation board 100, ensuring the structural strength, compressive strength, and overall rigidity of the metal decorative insulation board 100, and improving the performance of the metal decorative insulation board 100.

[0069] See Figure 2 In one embodiment, the metal decorative panel 110 includes a panel body 111 and a plurality of flanges 112. The panel body 111 is attached to the surface of the decorative backing plate 120 facing away from the insulation layer 130. The plurality of flanges 112 surround the edge of the panel body 111 and are bent relative to the panel body 111 toward the insulation layer 130. The flanges 112 at least partially abut against the edge of the insulation layer 130. The flanges 112 are used to fix the metal decorative panel 110 to the fixing brackets 300 of the metal decorative insulation assembly 10.

[0070] The metal-faced insulation board 100 is typically square, but optionally, it can be rectangular or square. The main body 111 is the main structure of the metal-faced panel 110. The main body 111 is square and has four folded edges 112. The four folded edges 112 are located around the main body 111 and are bent towards the insulation layer 130 relative to the main body 111.

[0071] In this way, the four folded edges 112 and the main body of the decorative panel 111 can form a box-shaped three-dimensional structure. The insulation layer 130 and the decorative backing plate 120 are disposed behind the metal decorative insulation board 100. The decorative backing plate 120 is attached to the surface of the main body of the decorative panel 111 facing the insulation layer 130, and the folded edges 112 cover the decorative backing plate 120 and at least part of the insulation layer 130. That is, the folded edges 112 can cover the decorative backing plate 120 and at least part of the insulation layer 130 along the thickness direction of the metal decorative insulation board 100.

[0072] The folded edge 112 on the metal decorative panel 110 facilitates the connection of the metal decorative panel 110 to the fixing bracket 300, thereby making it easier to fix the metal decorative insulation board 100 to the building wall 70. The connection between the metal decorative panel 110 and the fixing bracket 300 via the folded edge 112 improves the reliability of the connection and prevents separation between the fixing bracket 300 and the metal decorative panel 110, thus enhancing the reliability of the connection between the metal decorative insulation board 100 and the building wall 70.

[0073] Specifically, fixing brackets 300 are provided on the edge of the metal-faced insulation board 100. The fixing brackets 300 fit against the folded edge 112 to fix the metal-faced insulation board 110 to the fixing brackets 300. After multiple metal-faced insulation boards 100 are attached to the outer wall of the building wall 70, the metal-faced insulation boards 100 can be fixed to the building wall 70 by anchoring the fixing brackets 300 through the anchors 200, so as to achieve reliable connection between the metal-faced insulation board 100 and the building wall 70.

[0074] Moreover, after the metal decorative panel 110 is connected to the fixed corner bracket 300 through the folded edge 112, the force transmission path and force transmission principle are clear. Under the pull of external forces such as wind, the metal decorative insulation board 100 transmits the force to the fixed corner bracket 300 through the folded edge 112, and then to the building wall 70 through the fixed corner bracket 300 and the anchor 200, so as to prevent the metal decorative insulation board 100 from detaching from the building wall 70 under the pull of external forces such as wind, thereby reducing safety hazards.

[0075] It should be noted that the folded edge 112 can partially or completely cover the edge of the insulation layer 130 along the thickness direction, as long as it facilitates the connection between the folded edge 112 and the fixed corner bracket 300, to ensure the reliability of the connection between the fixed corner bracket 300 and the metal decorative panel 110. Optionally, the dimension of the folded edge 112 along the thickness direction of the metal decorative insulation board 100 is greater than or equal to 30mm.

[0076] Optionally, the folded edge 112 and the decorative panel body 111 are integrally formed. This ensures the structural strength of the metal decorative insulation board 100 and prevents breakage at the connection between the folded edge 112 and the decorative panel. Optionally, the metal decorative insulation assembly 10 also includes rivet screws 500, which pass through the fixing brackets 300 and are installed on the folded edge 112 to achieve a reliable connection between the fixing brackets 300 and the metal decorative panel 110.

[0077] See Figure 1 and Figure 2In one embodiment, the thickness of the metal decorative panel 110 ranges from 1mm to 1.4mm. A thickness of 1mm to 1.4mm ensures the structural strength and compressive strength of the metal decorative panel 110, thereby improving the performance of the metal-faced insulation board 100 and facilitating the construction of secondary decorative materials. Simultaneously, it ensures a smooth and flat outer surface of the metal decorative panel 110, thus guaranteeing its aesthetic appearance.

[0078] For example, the thickness of the metal decorative panel 110 is 1.2 mm. Of course, in other embodiments, the thickness of the metal decorative panel 110 may also be 1.1 mm, 1.3 mm, 1.4 mm or other dimensions, as long as the structural strength, compressive strength and smoothness of the outer surface of the metal decorative panel 110 are guaranteed.

[0079] See Figure 1 and Figure 2 In one embodiment, the thickness of the insulation layer 130 ranges from 50mm to 150mm. A thickness of 50mm to 150mm ensures the insulation effect of the insulation layer 130 on the building wall 70, meeting actual insulation requirements. For example, the thickness of the insulation layer 130 is 100mm. Of course, in other embodiments, the thickness of the insulation layer 130 can also be 90mm, 120mm, or other dimensions, as long as the insulation effect is guaranteed.

[0080] See Figure 1 and Figure 2 In one embodiment, the thickness of the decorative backing plate 120 ranges from 6mm to 10mm. With a thickness in the range of 6mm to 10mm, the decorative backing plate 120 can reliably support the metal decorative panel 110, mitigating the susceptibility of the metal decorative panel 110 and further enhancing the overall rigidity of the metal decorative insulation board 100, thereby ensuring the performance of the metal decorative insulation board 100.

[0081] For example, the thickness of the decorative backing panel 120 is 8 mm, and it is supported by the low-metal decorative panel 110 to enhance the overall rigidity of the metal decorative insulation board 100. Of course, in other embodiments, the thickness of the decorative backing panel 120 may also be 6 mm, 9 mm, or other sizes, as long as it can support the metal decorative panel 110 and improve the overall rigidity of the metal decorative insulation board 100.

[0082] See Figure 1 and Figure 2In one embodiment, the thickness of the thermal insulation backing board 140 ranges from 2mm to 6mm. A thickness of 2mm to 6mm allows for stable adhesion between the adhesive 400 and the thermal insulation backing board 140, facilitating its attachment to the outer wall of the building wall 70.

[0083] For example, the insulation backing board 140 has a thickness of 4 mm to ensure stable adhesion between the adhesive 400 and the insulation backing board 140, facilitating the adhesion of the insulation backing board 140 to the outer wall of the building wall 70. Of course, in other embodiments, the thickness of the insulation backing board 140 may also be 3 mm, 6 mm, or other dimensions.

[0084] See Figure 1 and Figure 2 In one embodiment, the insulation layer 130 is made of vertically filament water-repellent rock wool. Vertically filament water-repellent rock wool has good tensile and compressive strength and can withstand huge pressure perpendicular to the wall surface (i.e., the thickness direction) to support the weight of the bonding surface and the metal decorative panel 110, prevent the metal decorative insulation board 100 from separating or falling off, and ensure the performance of the metal decorative insulation board 100.

[0085] Meanwhile, the vertical-fiber water-repellent rock wool material also possesses good freeze-thaw resistance and stability, enhancing the structural stability of the metal-faced insulation board 100, making it less prone to deformation, and providing thermal insulation properties for the insulation and decoration of the building wall 70. Furthermore, the vertical-fiber water-repellent rock wool material also has good waterproof performance, making it more difficult for moisture to penetrate into the interior of the board along the fibers, thus ensuring the performance of the metal-faced insulation board 100.

[0086] See Figure 1 and Figure 2 In one embodiment, the decorative backing board 120 is made of calcium silicate board. Calcium silicate board has high stability. After the decorative backing board 120 is made of calcium silicate board, the decorative backing board 120 can support the metal decorative panel 110, improve the overall rigidity of the metal decorative insulation board 100, and thus improve the load-bearing capacity of the metal decorative insulation board 100.

[0087] See Figure 1 and Figure 2 In one embodiment, the thermal insulation backing board 140 is made of calcium silicate board. Calcium silicate board has high stability. After the thermal insulation backing board 140 is made of calcium silicate board, the thermal insulation backing board 140 can be stably bonded to the adhesive 400, which makes it easy to stick the thermal insulation backing board 140 to the outer wall of the building wall 70.

[0088] The metal-faced insulation board 100 of this application, after having a metal-faced panel 110 installed on the outside of the facing backing board 120, can make the outer surface of the metal-faced insulation board 100 smooth and flat, improve the compressive strength of the metal-faced insulation board 100, and facilitate the construction of secondary decorative materials. At the same time, the facing backing board 120 can reinforce the easily deformable nature of the metal-faced panel 110, further increasing the overall rigidity of the metal-faced insulation board 100. The bonding between the insulation backing board 140 and the adhesive 400 can achieve the stability of the adhesion of the metal-faced insulation board 100, so that the metal-faced insulation board 100 is stably attached to the outer wall of the building wall 70, avoiding cracking of the metal-faced insulation board 100 and ensuring the performance of the metal-faced insulation board 100.

[0089] See Figure 1 and Figure 2 This application also provides a metal-clad insulation assembly 10, including a plurality of fixing corner brackets 300, a plurality of anchors 200, and a metal-clad insulation board 100 as described in any of the above embodiments. The insulation backing board 140 of the plurality of metal-clad insulation boards 100 is adhered to the surface of the building's exterior wall by an adhesive 400. Two fixing corner brackets 300 are provided between two adjacent metal-clad insulation boards 100. The metal cladding panel 110 in each metal-clad insulation board 100 is connected to at least one fixing corner bracket 300. The anchors 200 pass through at least one fixing corner bracket 300 and are fixed in the building wall 70.

[0090] The metal-clad insulation assembly 10 includes multiple metal-clad insulation panels 100, which can cover the outer wall of the building wall 70. The multiple metal-clad insulation panels 100 are arranged in rows and columns, and there is a certain gap between any two adjacent metal-clad insulation panels 100, so as to fix the metal-clad insulation panels 100 to the outer wall of the building wall 70.

[0091] In the metal-clad insulation panel 100, after the metal-clad panel 110 is connected to the fixing bracket 300 via the folded edge 112, the fixing bracket 300 is located between two adjacent metal-clad insulation panels 100, and the fixing bracket 300 can fit against the outer wall of the building wall 70. The anchor 200 can pass through the fixing bracket 300 and be installed into the building wall 70 to reliably fix the metal-clad insulation panel 100 to the building wall 70. Moreover, the anchor 200 is installed into the building wall 70 through at least one fixing bracket 300.

[0092] Furthermore, an anchoring hole 701 is formed by vertically drilling at the position corresponding to the fixing angle bracket 300 on the building wall 70. This anchoring hole 701 is the hole for installing the anchor 200. After the metal-faced insulation board 100 is installed on the wall, the fixing angle bracket 300 is aligned with the anchoring hole 701. The anchor 200 can be installed into the anchoring hole 701 by passing through the fixing angle bracket 300, so as to reliably fix the metal-faced insulation board 100 to the building wall 70 and facilitate the installation of the anchor 200 into the building wall 70.

[0093] Furthermore, after vertically drilling anchor holes 701 into the building wall 70, the anchor holes 701 need to be cleaned to facilitate the installation of the anchor 200 into them. Optionally, the anchor 200 is a chemical anchor or an expansion bolt. Optionally, the depth of the anchor hole 701 is greater than the length of the anchor 200. In this way, the anchor 200 can be effectively installed into the anchor hole 701.

[0094] See Figure 1 and Figure 2 In one embodiment, the diameter of the anchor 200 is in the range of 6mm to 10mm. The diameter of the anchor 200 being in the range of 6mm to 10mm ensures the connection strength between the anchor 200 and the building wall 70, improves the reliability of the connection between the anchor 200 and the building wall 70, and thus improves the reliability of the connection between the metal-faced insulation board 100 and the building wall 70.

[0095] For example, the diameter of the anchor 200 is 8 mm or 10 mm. That is, a drill bit with a diameter of 8 mm or 10 mm can be used to drill a vertical hole in the building wall 70 to form an anchoring hole 701 of matching size, which facilitates the installation of the anchor 200. Of course, in other embodiments, the diameter of the anchor 200 may be other.

[0096] It should be noted that the connection between the anchor 200 and the building wall 70 is achieved by using specified anchors 200, such as chemical anchors or expansion bolts, in conjunction with adhesive. The adhesive here refers to structural adhesives with specific construction process requirements or specific properties, such as no-clean chemical anchor adhesive or high-penetration epoxy adhesive.

[0097] During construction and installation, the existing installation process should not be changed. Use anchors 200 with a diameter of 8mm or 10mm. Saturate the anchors 200 with the non-cleaned adhesive and screw them into the anchoring holes 701 for anchoring. It should be noted that the overall performance of anchors 200 meets the material requirements of JGT366 "Anchors for External Wall Insulation"; the adhesive (non-cleaned) must be a thixotropic, room-temperature curing structural adhesive, and its overall performance must meet the requirements for structural adhesives used for rebar installation in GB50367 "Code for Design of Strengthening Concrete Structures".

[0098] Optionally, the depth of the anchor hole 701 is 10mm greater than the length of the anchor bolt of the anchor 200 to facilitate the installation of the anchor 200. Optionally, the effective anchoring length of the anchor 200 and the anchor hole 701 is greater than 65mm. This ensures the effective connection length between the anchor 200 and the anchor hole 701, improves the reliability of the connection between the anchor 200 and the building wall 70, and thus reliably fixes the metal-faced insulation board 100 to the building wall 70.

[0099] See Figure 2 In one embodiment, the fixed corner bracket 300 includes a first fixed body and a second fixed body, which are arranged perpendicularly. The first fixed body is connected to the folded edge 112 of the metal decorative panel 110, and the second fixed body is attached to the outer wall of the building wall 70. The anchor 200 passes through the second fixed body and is installed in the building wall 70.

[0100] In other words, the fixing angle bracket 300 is L-shaped. Thus, the fixing angle bracket 300 is connected to the folded edge 112 of the metal decorative panel 110 via a first fixing body along the thickness direction, and adheres to the outer wall of the building wall 70 via a second fixing body parallel to the direction of the building wall 70. The anchor 200 passes through the second fixing body and can then be installed on the building wall 70. Optionally, the first fixing body and the second fixing body are an integral structure.

[0101] See Figures 1 to 3 In one embodiment of this application, two fixed corner brackets 300 are correspondingly arranged between two adjacent metal-faced insulation panels 100 and are stacked on the outer wall of the building wall 70. Anchors 200 pass through the two fixed corner brackets 300 and are installed in the building wall 70. Figure 3 for Figure 1 The diagram shows a front view of an embodiment of the metal-clad insulation assembly 10. Specifically, two fixing brackets 300 are simultaneously connected by a single anchor 200 to simultaneously fix two adjacent metal-clad insulation panels 100 to the building wall 70. This reduces the number of anchors 200 and lowers costs.

[0102] See Figure 1 , Figure 2 and Figure 4 In another embodiment of this application, two fixed corner brackets 300 between two adjacent metal-faced insulation boards 100 are staggered and abut against the outer wall of the building wall 70. Each anchor 200 passes through the corresponding fixed corner bracket 300 and is installed in the building wall 70. Figure 4 for Figure 1The diagram shows a front view of another embodiment of the metal-clad insulation assembly 10. Specifically, each anchor 200 secures its corresponding fixing bracket 300 to the building wall 70. This reduces the stress on the anchor 200, ensuring reliable installation of the metal-clad insulation panel 100 onto the building wall 70.

[0103] See Figure 1 and Figure 2 In one embodiment, the metal-finished insulation assembly 10 further includes rivet screws 500, which pass through fixing brackets 300 and are installed on the metal-finished panel 110. The rivet screws 500 pass through the fixing brackets 300 and are installed on the folded edge 112 to achieve a reliable connection between the fixing brackets 300 and the metal-finished panel 110. In this way, the force on the metal-finished insulation board 100 can be transmitted to the fixing brackets 300 through the rivet screws 500, and then to the building wall 70 through the fixing brackets 300.

[0104] See Figure 1 and Figure 2 In one embodiment, at least one of expanding foam 600, waterproof adhesive stick, and waterproof edge sealing adhesive is used to fill the gaps between adjacent metal-faced insulation panels 100. It is understood that after the anchor 200 is installed into the building wall 70 through the fixing bracket 300, there will be a certain gap between two adjacent metal-faced insulation panels 100, requiring waterproofing treatment to ensure waterproofing effectiveness.

[0105] It should be noted that the waterproof material used to fill the gaps between two adjacent metal-faced insulation panels 100 is generally unrestricted, as long as it provides waterproofing. In this embodiment, expanding foam 600, waterproof adhesive, and waterproof edge sealant are used to fill the gaps between adjacent metal-faced insulation panels 100. Specifically, expanding foam 600 is first filled between adjacent metal-faced insulation panels 100, then elastic waterproof adhesive is used to fill the gaps, and finally, waterproof edge sealant is applied to seal the surface, achieving a triple waterproofing mechanism.

[0106] Of course, in other embodiments, expanding foam 600 can be filled between adjacent metal decorative panels 110 to achieve waterproofing; waterproof glue sticks can be filled between adjacent metal decorative panels 110 to achieve waterproofing; waterproof edge sealing glue can be filled between adjacent metal decorative panels 110 to achieve waterproofing; or at least two of expanding foam 600, waterproof glue sticks, and waterproof edge sealing glue can be filled between adjacent metal decorative insulation boards 100.

[0107] See Figure 1 and Figure 2In one embodiment, the adhesive 400 is an adhesive mortar, the thickness of the adhesive 400 is greater than or equal to 20 mm, and the coverage area of ​​the adhesive 400 on the insulation backing board 140 of the metal-faced insulation board 100 is greater than or equal to 60%. Using adhesive mortar as the adhesive 400, the adhesive mortar is thickly applied to the surface of the insulation backing board 140, and the metal-faced insulation board 100 is adhered to the outer wall of the building wall 70 via the adhesive mortar.

[0108] Furthermore, the adhesive 400 has a thickness greater than 20 mm to ensure that the metal-faced insulation board 100 is reliably adhered to the outer wall of the building wall 70. Moreover, the adhesive 400 covers at least 60% of the insulation backing board 140 of the metal-faced insulation board 100 to increase the contact area between the metal-faced insulation board 100 and the outer wall of the building wall 70, thereby improving the reliability of the connection between the metal-faced insulation board 100 and the building wall 70.

[0109] See Figure 1 and Figure 2 In one embodiment, at least six anchors 200 are provided per square meter of metal-faced insulation assembly 10. In this way, each square meter of metal-faced insulation assembly 10 is fixed to the building wall 70 by at least six anchors 200, further improving the reliability of the connection between the metal-faced insulation board 100 and the wall.

[0110] During installation, the metal-clad insulation assembly 10 of this application first forms an integral metal-clad insulation board 100. Then, using rivet screws 500, fixing brackets 300 are inserted and installed onto the folded edge 112 of the metal-clad panel 110 to fix the fixing brackets 300 to the metal-clad insulation board 100. Subsequently, adhesive 400 is applied to the surface of the insulation backing board 140 in the metal-clad insulation board 100. Anchor holes 701 are formed by vertically drilling holes on the outer wall of the building wall 70 at the positions corresponding to the fixing brackets 300, and the anchor holes 701 are cleaned.

[0111] The metal-faced insulation board 100 is mounted on the wall, and then adhered to the outer wall of the building wall 70 using adhesive 400, achieving initial fixation of the metal-faced insulation board 100. At this time, the fixing angle bracket 300 is attached to the outer wall of the building wall 70. The anchor 200 is soaked with structural adhesive and inserted through the fixing angle bracket 300 into the anchor hole 701, achieving connection between the fixing angle bracket 300 and the building wall 70, thereby reliably fixing the metal-faced insulation board 100 to the building wall 70. Expanding foam 600 is applied between two adjacent metal-faced insulation boards 100, waterproof glue sticks are filled on the expanding foam 600, and waterproof edge sealing glue is applied to the outside of the waterproof glue sticks to achieve triple waterproof sealing.

[0112] A pull-out test is performed on the building wall 70 to determine the anchoring force between the metal decorative panel 110 and the building wall 70.

[0113] Experiment 1: A simulation test was conducted using Class E wall material ALC (block B05) as the building wall material. Class E wall material ALC (block B05) refers to a type of block made of autoclaved lightweight sand aerated concrete with a density grade of B05 (approximately 500 kg / m³) and a strength grade of approximately A3.5. Walls constructed with this type of block belong to Class E wall material (lightweight porous wall material) in engineering classification.

[0114] Fifteen test points were set on the building wall 70, and an anchor 200 was installed at each test point without being fully coated with adhesive. Five test points were grouped together. After applying a pull-out force to the metal veneer insulation assembly 10, the pull-out force at each test point is shown in Table 1.

[0115] Table 1

[0116]

[0117] Experiment 2: A simulation test was conducted using Class E wall material ALC (block B05) as the building wall material. Class E wall material ALC (block B05) refers to a type of block made of autoclaved lightweight aerated concrete with a density grade of B05 (approximately 500 kg / m³) and a strength grade of approximately A3.5. Walls constructed with this type of block belong to Class E wall material (lightweight porous wall material) in engineering classification.

[0118] Five test points were set on the building wall 70, and an anchor 200 was installed at each test point, with the anchor 200 fully coated with adhesive. After applying a pull-out force to the metal-faced insulation assembly 10, the pull-out force at each test point is shown in Table 2.

[0119] Table 2

[0120]

[0121] Comparing Experiment 1 and Experiment 2, it can be seen that after the anchor 200 is soaked in structural adhesive and installed into the anchor hole 701 of the building wall 70, the anchor 200 can withstand greater pull-out force, improving the reliability of the metal-faced insulation board 100. Through calculation and experimental verification, scientific mechanical data has been obtained, showing that the metal-faced insulation board 100 is suitable for the exterior surfaces of low-rise, high-rise, and super high-rise buildings, enriching the application scenarios of the board and avoiding phenomena such as peeling and cracking under stress.

[0122] The metal-clad insulation assembly 10 of this application uses a fixing angle bracket 300 to connect with the metal cladding panel 110 of the metal-clad insulation board 100. Anchors 200 are installed through the fixing angle bracket 300 and attached to the building wall 70 to fix the metal-clad insulation board 100 to the building wall 70. In this way, the metal-clad insulation board 100 is fixed to the building wall 70 by the cooperation of the anchors 200 and the fixing angle brackets 300. At the same time, the metal-clad insulation board 100 is also glued and fixed to the outer wall of the building wall 70 by adhesive 400. The metal-clad insulation board 100 is reliably fixed to the outer wall of the building wall 70 by adhesive and anchoring, avoiding cracking of the metal-clad insulation assembly 10 and ensuring the performance of the metal-clad insulation assembly 10.

[0123] See Figure 1 , Figure 2 and Figure 5 , Figure 5 This is a flowchart illustrating the installation process of the metal-finished insulation assembly 10 according to one embodiment of this application. This application provides an installation process for a metal-finished insulation board 100, which is applied to the metal-finished insulation assembly 10 as described in any of the above embodiments. The installation process includes at least the following steps:

[0124] S1, the metal decorative panel 110 of the metal decorative insulation board 100 is connected to the fixed corner bracket 300 by the rivet screw 500;

[0125] S2, apply adhesive 400 to the surface of the insulation backing board 140 of the metal-faced insulation board 100;

[0126] S3, Drill holes in the building wall 70 to form anchor holes 701, and clean the anchor holes 701.

[0127] S4, apply adhesive 400 to the outer wall of building wall 70 so that multiple metal-faced insulation boards 100 are mounted on the wall;

[0128] S5, dip the anchor 200 in adhesive and install it into the anchor hole 701 of the building wall 70 through the fixing bracket 300;

[0129] S6, apply expanding foam 600 between two adjacent metal-finished insulation boards 100, fill the expanding foam 600 with waterproof glue sticks, and fill the outside of the waterproof glue sticks with waterproof edge sealing glue.

[0130] During installation, the metal-clad insulation assembly 10 of this application first forms an integral metal-clad insulation board 100. Then, using rivet screws 500, fixing brackets 300 are inserted and installed onto the folded edge 112 of the metal-clad panel 110 to fix the fixing brackets 300 to the metal-clad insulation board 100. Subsequently, adhesive 400 is applied to the surface of the insulation backing board 140 in the metal-clad insulation board 100. Anchor holes 701 are formed by vertically drilling holes on the outer wall of the building wall 70 at the positions corresponding to the fixing brackets 300, and the anchor holes 701 are cleaned.

[0131] The metal-faced insulation board 100 is mounted on the wall, and then adhered to the outer wall of the building wall 70 using adhesive 400, achieving initial fixation of the metal-faced insulation board 100. At this time, the fixing angle bracket 300 is attached to the outer wall of the building wall 70. The anchor 200 is soaked with structural adhesive and inserted through the fixing angle bracket 300 into the anchor hole 701, achieving connection between the fixing angle bracket 300 and the building wall 70, thereby reliably fixing the metal-faced insulation board 100 to the building wall 70. Expanding foam 600 is applied between two adjacent metal-faced insulation boards 100, waterproof glue sticks are filled on the expanding foam 600, and waterproof edge sealing glue is applied to the outside of the waterproof glue sticks to achieve triple waterproof sealing.

[0132] See Figure 1 and Figure 2 In one embodiment, the adhesive 400 is an adhesive mortar, the thickness of the adhesive 400 is greater than or equal to 20 mm, and the coverage area of ​​the adhesive 400 on the insulation backing board 140 of the metal-faced insulation board 100 is greater than or equal to 60%. Using adhesive mortar as the adhesive 400, the adhesive mortar is thickly applied to the surface of the insulation backing board 140, and the metal-faced insulation board 100 is adhered to the outer wall of the building wall 70 via the adhesive mortar.

[0133] Furthermore, the adhesive 400 has a thickness greater than 20 mm to ensure that the metal-faced insulation board 100 is reliably adhered to the outer wall of the building wall 70. Moreover, the adhesive 400 covers at least 60% of the insulation backing board 140 of the metal-faced insulation board 100 to increase the contact area between the metal-faced insulation board 100 and the outer wall of the building wall 70, thereby improving the reliability of the connection between the metal-faced insulation board 100 and the building wall 70.

[0134] See Figure 1 and Figure 2 In one embodiment, at least six anchors 200 are provided per square meter of metal-faced insulation assembly 10. In this way, each square meter of metal-faced insulation assembly 10 is fixed to the building wall 70 by at least six anchors 200, further improving the reliability of the connection between the metal-faced insulation board 100 and the wall.

[0135] See Figure 1and Figure 2 In one embodiment, the diameter of the anchor 200 is in the range of 6mm to 10mm. The diameter of the anchor 200 being in the range of 6mm to 10mm ensures the connection strength between the anchor 200 and the building wall 70, improves the reliability of the connection between the anchor 200 and the building wall 70, and thus improves the reliability of the connection between the metal-faced insulation board 100 and the building wall 70.

[0136] For example, the diameter of the anchor 200 is 8 mm or 10 mm. That is, a drill bit with a diameter of 8 mm or 10 mm can be used to drill a vertical hole in the building wall 70 to form an anchoring hole 701 of matching size, which facilitates the installation of the anchor 200. Of course, in other embodiments, the diameter of the anchor 200 may be other.

[0137] It should be noted that the connection between the anchor 200 and the building wall 70 is achieved by using specified anchors 200, such as chemical anchors or expansion bolts, in conjunction with adhesive. The adhesive here refers to structural adhesives with specific construction process requirements or specific properties, such as no-clean chemical anchor adhesive or high-penetration epoxy adhesive.

[0138] During construction and installation, the existing installation process is not changed. Anchors 200 with a diameter of 8mm or 10mm are used. The anchors 200 are saturated with non-cleaning adhesive and screwed into the anchoring hole 701 for anchoring.

[0139] It should be noted that the overall performance of anchor 200 meets the material requirements of JGT366 "Anchor Bolts for External Wall Insulation"; the adhesive is required to be a thixotropic room temperature curing structural adhesive for non-cleaning holes, and its overall performance meets the requirements of GB50367 "Code for Design of Strengthening Concrete Structures" for structural adhesives used in rebar installation.

[0140] Optionally, the depth of the anchor hole 701 is 10mm greater than the length of the anchor bolt of the anchor 200 to facilitate the installation of the anchor 200. Optionally, the effective anchoring length of the anchor 200 and the anchor hole 701 is greater than 65mm. This ensures the effective connection length between the anchor 200 and the anchor hole 701, improves the reliability of the connection between the anchor 200 and the building wall 70, and thus reliably fixes the metal-faced insulation board 100 to the building wall 70.

[0141] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0142] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
