[0039] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0041] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the structures and / or processing steps closely related to the solution of this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0042] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0043] In the following specific embodiments, the wall panels in the exterior wall structure can be made of any material. For example, the wall panels can be one or more combinations of metal panels, tempered glass panels, ceramic tiles, stone slabs, and concrete slabs. The wall panels can be fixed to the wall in a dry-hanging, wet-hanging, or partially dry-hanging and partially wet-hanging manner. Depending on the specific structure of the exterior wall structure, it can be used to achieve various functions. For example, a heat-insulating filling layer can be used in the exterior wall structure to achieve heat insulation or thermal insulation; a vacuum insulation layer can be used in the exterior wall structure to achieve sound insulation; and wall decorations can be added to the exterior wall structure to improve the aesthetics of the building. The above structures can also be used in combination to enable the exterior wall structure to achieve multiple functions simultaneously. The following examples illustrate different components in the exterior wall structure and the overall structure of the exterior wall structure.

[0044] First, the usage environment of the exterior wall structure will be described with reference to Figure 1. As shown in Figure 1, the exterior wall structure includes exterior wall fixing nodes 10, wall panels 20, and wall body 30. The wall body 30 is the interior wall structure of the building. The wall panels 20 are fixedly connected to the wall body 30 through the exterior wall fixing nodes 10. Multiple wall panels 20 are arranged side by side to cover the wall body 30. The exterior wall fixing nodes 10 include connecting frames 50 and connecting plates 200. The connecting frames 50 are used to fix the wall panels 20, and the connecting plates 200 are used to fix the wall body 30. At the same time, the connecting frames 50 and connecting plates 200 are fixedly connected to fix the wall panels 20 and the wall body 30. The wall panels 20 and some structures in the exterior wall fixing nodes 10 are combined to form a composite wall panel assembly 11. The structure of the composite wall panel assembly 11 will be described below with reference to various embodiments.

[0045] In some embodiments, as shown in FIG2, the composite wall panel assembly 11 includes: a wall panel 20, a connecting frame 50, and a filling structure 40. The connecting frame 50 surrounds and forms a closed shape and is fixed to a first wall surface of the wall panel 20. The first wall surface is a long and wide surface of the wall panel 20. In the assembled state, the long and wide surface faces the wall 30. It can be understood that the connecting frame 50 forms a frame structure on a long and wide surface of the wall panel 20, and the frame surrounds and forms a receiving space by connecting the ends. The connecting frame 50 can be a structure formed integrally, or it can be formed by splicing multiple parts.

[0046] The filling structure 40 is fixed to the first wall surface of the wall panel 20, and part of the filling structure 40 is housed within the space formed by the connecting frame 50. The filling structure 40 within this space contacts the connecting frame 50. This can be understood as the filling structure 40 and the connecting frame 50 being fixed to the same side of the wall panel 20. The connecting frame 50 surrounds and contacts the filling structure 40, allowing the connecting frame 50 to bear a portion of the weight of the filling structure 40. Furthermore, when the filling structure 40 is formed of loose material, the connecting frame 50 can also tighten the loose material, thereby reducing the risk of partial detachment due to the loose structure and improving the fixing reliability of the filling structure 40 to the wall panel 20. The filling structure 40 can be any structure with thermal insulation function. For example, the filling structure 40 includes a thermal insulation layer formed by thermal insulation material; for example, the filling structure 40 includes multiple thermal insulation panels, forming a vacuum cavity between adjacent thermal insulation panels.

[0047] Optionally, in the exterior wall structure, the connecting frame 50 is used to be fixedly connected to multiple fixing plates 200 in Figure 1 at the same time, so that the load borne by the wall panel 20 can be transferred to multiple fixing plates 200 at the same time, thereby reducing the load on a single fixing plate 200 and improving the overall structural strength of the exterior wall structure.

[0048] This application provides a composite wall panel assembly, which includes: a wall panel, a connecting frame fixed to the wall panel and forming a closed shape, and a filling structure with thermal insulation function. Part of the filling structure is accommodated within the space formed by the connecting frame, and the filling structure located in the space is in contact with the connecting frame, so that the connecting frame can bear part of the weight of the filling structure. When the filling structure is formed of loose material, the connecting frame can also tighten the loose material, thereby reducing the risk of the filling structure falling off due to its loose structure, and thus improving the fixing reliability of the filling structure and the wall panel.

[0049] In some embodiments, as shown in FIG2, the closed shape formed by the connecting frame 50 is a rectangle. The connecting frame 50 is fixedly connected to the fixing plates 200 in the four adjacent external wall fixing nodes 10. It can be understood that the wall panel 20 is generally a cube, and multiple external wall fixing nodes 10 are arranged at intervals around the outer edge of the wall panel 20, so that each external wall fixing node 10 is arranged along the rectangle. Setting the closed shape formed by the connecting frame 50 as a rectangle allows the extension direction of the connecting frame 50 to be adapted to the arrangement direction of each external wall fixing node 10, thereby facilitating the fixed connection of the connecting frame 50 to each external wall fixing node 10. It should be noted that the closed shape formed by the connecting frame 50 can also be adaptively changed according to the different shapes of the wall panel 20. For example, when the wall panel 20 is a hexagonal prism, the closed shape formed by the connecting frame 50 is a hexagon.

[0050] In some embodiments, as shown in FIG2, the connecting frame 50 is an integral structure. By forming the connecting frame 50 into an integral structure, the structural strength of the connecting frame 50 can be improved. The integral structure can be obtained by integral molding. For example, the connecting frame 50 is integrally formed by casting or forging. The integral structure can also be formed by different disassembly and fixing methods. For example, the connecting frame 50 includes multiple parts, and the parts are fixedly connected by welding to form the integral structure of the connecting frame 50.

[0051] In some embodiments, as shown in FIG3, the connecting frame 50 includes a plurality of connecting structures 100. The structure of each connecting structure 100 can be any structure that can be spliced ​​to form the connecting frame 50. In each embodiment, there is no limitation on the shape of the connecting structures 100. After the connecting structures 100 are assembled in a certain position, a spliced ​​connecting frame 50 can be obtained, thereby reducing the manufacturing difficulty and manufacturing cost of the connecting frame 50. The following describes the method of forming the connecting frame 50 by splicing the connecting structures 100 in conjunction with various embodiments.

[0052] In some embodiments, as shown in FIG4, adjacent connecting structures 100 in the connecting frame 50 are fixedly connected by corner brackets 51. The corner brackets 51 are sheet-like structures, each comprising two parts, and the extension directions of the two parts form a certain angle between them. This angle can be, for example, a right angle. By fixing the two parts of the corner brackets 51 to the outer surfaces of the two connecting structures 100, the two connecting structures 100 can be fixedly connected and the extension directions of the two connecting structures 100 can form a target angle. By connecting multiple connecting structures 100 end to end with multiple corner brackets 51, multiple connecting structures can be spliced ​​together to form the connecting frame 50.

[0053] Optionally, as shown in Figure 4, the positioning end in the connecting structure 100 is fixedly connected by a corner bracket 51. This positioning end is the end of the connecting structure 100 away from the wall panel 20 in the first direction (the first direction is shown by the solid arrow in Figure 4). If the corner bracket 51 is set at the end close to the wall panel 20, it may cause assembly interference between the corner bracket 51 and the wall panel 20. Setting the corner bracket 51 at the end away from the wall panel 20 can reduce the risk of motion interference between the corner bracket 51 and the wall panel 20.

[0054] Optionally, as shown in Figure 5, the positioning end of the connecting structure 100 has a positioning structure 191. The positioning structure 191 is used to abut against the corner bracket 51 to position the corner bracket 51 to the target position. It can be understood that the abutting force applied to the corner bracket 51 by the positioning structure 191 keeps the corner bracket 51 in the target position. Thus, during the assembly process, there is no need to use an additional positioning device or the assembly personnel's hands to position the corner bracket 51, which facilitates fixing the corner bracket 51 to the target position. The target position is the position where the mounting hole of the corner bracket 51 and the connecting hole of the connecting structure 100 are aligned. Moreover, by setting the positioning structure 191, it is also beneficial to the automatic assembly of the connecting frame 50. That is, during the automated assembly process, after the corner bracket 51 is moved to the vicinity of the target position by the moving device, the corner bracket 51 can be positioned to the target position by abutting against the positioning structure 191, and the corner bracket 51 can still be kept in the target position after the moving device releases the corner bracket 51. It should be noted that the positioning structure 191 can be any structure that can hold the corner piece 51 in the target position by resisting force. For example, the positioning structure 191 can be a positioning groove or a positioning protrusion, or one part can be a positioning groove and the other part can be a positioning protrusion. The structure of the positioning structure 191 will be described by way of example below with reference to Figures 5 to 7.

[0055] As shown in Figure 5, the positioning structure 191 includes a positioning cavity 192. The positioning cavity 192 is formed by the positioning end being recessed along a first direction (the first direction is shown by the arrow in Figure 5). The positioning cavity 192 is used to accommodate at least a portion of the corner piece 51. It can be understood that the positioning cavity 192 has an opening facing the first direction. When the corner piece 51 is extended into the positioning cavity 192 through the opening along the first direction, the corner piece 51 can abut against the inner wall of the positioning cavity 192, thereby positioning the corner piece 51 at the target position. Optionally, the positioning ends of adjacent connecting structures 100 in the connecting frame 50 all form positioning cavities 192. The positioning cavities 192 of the two connecting structures 100 are connected and form the same shape as the corner piece 51 perpendicular to the thickness direction, so that the positioning cavities 192 of the two splicing structures 100 can be spliced ​​to form a cavity for accommodating the corner piece 51.

[0056] As shown in Figure 6, the positioning structure 191 includes a positioning protrusion 193, which protrudes from the positioning end along a first direction (as indicated by the arrow in Figure 6). The positioning protrusion 193 abuts against the corner code 51 in a direction perpendicular to the first direction. This can be understood as the corner code 51 abutting against the positioning end to restrict the movement of the corner code 51 relative to the connecting structure 100 in the first direction, and the positioning protrusion 193 restricts the movement of the corner code 51 relative to the connecting structure 100 in a direction perpendicular to the first direction, thereby enabling the corner code 51 to be positioned at the target position. It should be noted that the corner code 51 can approach the positioning protrusion 193 from different directions. For example, the corner code 51 approaches the positioning protrusion 193 along the first direction and abuts against the positioning protrusion 193 in a direction perpendicular to the first direction. For example, the corner code 51 approaches the positioning protrusion 193 in a direction perpendicular to the first direction after approaching the positioning end and abuts against the positioning protrusion 193.

[0057] Optionally, as shown in Figure 6, the corner bracket 51 includes a first connecting portion 511 and a second connecting portion 512. A first included angle is formed between the extending directions of the first connecting portion 511 and the second connecting portion 512, for example, 90 degrees. The first portion 511 and the second portion 512 are respectively connected to two adjacent connecting structures 100 in the connecting frame 50, thereby enabling the connecting structures 100 to be spliced ​​to form the connecting frame 50. Simultaneously, the positioning protrusions 193 of adjacent connecting structures 100 in the connecting frame 50 abut against the first connecting portion 511 and the second connecting portion 512, and the two positioning protrusions... The first included angle is formed between the extension directions of the protrusions 193 of the two adjacent connecting structures 100. This can be understood as the two connecting protrusions 193 of the two adjacent connecting structures 100 splicing together to form a protrusion structure with the same shape as the corner piece 51 perpendicular to the thickness direction. The two connecting protrusions 193 can abut against the two connecting parts of the corner piece 51 in two orthogonal directions perpendicular to the first direction (e.g., the second direction and the third direction), thereby restricting the movement of the corner piece 51 relative to the connecting structure 100 in the two orthogonal directions. That is, by simplifying the structure of the connecting protrusions 193 of a single connecting structure 100, the manufacturing cost of the connecting structure 100 is reduced.

[0058] Optionally, as shown in Figure 7, the connecting structure 100 has multiple positioning protrusions 193, each positioning protrusion 193 being spaced apart along a second direction (as indicated by the dashed arrow in Figure 7). Adjacent positioning protrusions 193 surround and form a positioning space. The inner wall of this positioning space is used to abut against the corner bracket 51. This can be understood as the positioning space having an opening facing a first direction (as indicated by the solid arrow in Figure 7). The corner bracket 51 is inserted into the positioning space through this opening along the first direction and abuts against the positioning protrusions 193 surrounding and forming the positioning space. Thus, the corner bracket 51 is positioned by two adjacent positioning protrusions 193. The clamping mechanism more reliably positions the corner bracket 51 to the target position. Meanwhile, two adjacent positioning spaces in the connecting frame 50 are used to accommodate the first connecting part 511 and the second connecting part 512 of the corner bracket 51, respectively. It can be understood that two adjacent positioning protrusions 193 in the connecting frame 50 form two positioning spaces. The two positioning spaces are connected and spliced ​​to form a space with the same shape as the corner bracket 51 perpendicular to the thickness direction. The first connecting part 511 and the second connecting part 512 can be positioned through the two positioning spaces, thereby simplifying the structure of the positioning protrusions 193 of the single connecting structure 100.

[0059] Optionally, as shown in Figure 7, in the first direction (as indicated by the solid arrow in Figure 7), the positioning protrusion 193 has a first guide surface 194. In the second direction (as indicated by the dashed arrow in Figure 7), the first guide surface 194 is located on the side closer to the corner bracket 51. It can be understood that during the process of moving the corner bracket 51 closer to the positioning protrusion 193 along the first direction, the corner bracket 51 can abut against the first guide surface 194. The cross-sectional area of ​​the positioning protrusion 193 decreases along the direction of the positioning end extending from the positioning protrusion 193. This cross-section is a plane perpendicular to the direction of the positioning protrusion 193 extending. During the process of moving the corner bracket 51 closer to the positioning protrusion 193 along the first direction, the first guide surface 194 can move the corner bracket 51 closer to the target position. During the automated assembly of the corner bracket 51 and the connecting structure 100, the moving structure can position the corner bracket 51 to the target position with the assistance of the first guide surface 194.

[0060] Optionally, the first connecting portion 511 and the second connecting portion 512 of the corner bracket 51 both have connecting holes. The number of connecting holes in the first portion 511 and the second connecting portion 512 is at least one. Multiple connecting holes can facilitate the leveling of the corner bracket 51, while a single connecting hole can enable the corner bracket 51 to be assembled with the connecting structure 100 more quickly.

[0061] As shown in Figure 8, adjacent connecting structures 100 in the connecting frame 50 are fixedly connected by corner brackets 52. The corner brackets 52 can be understood as block structures comprising two parts whose extending directions form an included angle, such as a right angle. By inserting the two parts of the corner brackets 52 into the slots 180 of the connecting structure 100, and then fixing the corner brackets 52 to the connecting structure 100 with screws, multiple connecting structures 100 are spliced ​​together to form the connecting frame 50. Optionally, adjacent connecting structures 100 can also be spliced ​​together using corner brackets 51 and corner brackets 52 to form the connecting frame 50. For example, adjacent connecting structures 100 are connected at their ends with insertion cavities using corner brackets 52, and at their ends without insertion cavities using corner brackets 51. It should be noted that the corner assembly 52 can be assembled with the connecting structure 100 in different ways. For example, the corner assembly 52 can be fixedly connected to the connecting structure 100 by connecting pins. Specifically, a clearance fit or an overfit is formed between the corner assembly 52 and the slot 180 of the connecting structure 100, and a pin hole is provided in the connecting structure 100. Adhesive is filled between the corner assembly 52 and the slot 180, and then the corner assembly 52 is fixedly connected to the connecting structure 100 by pins. For example, the corner assembly 52 can also be fixedly connected to the connecting structure 100 by extrusion. Specifically, the corner assembly 52 and the slot 180 of the connecting structure 100 form an interference fit by simultaneously extruding the corner assembly 52 into the slots 180 of two adjacent connecting structures 100, and the connecting structure 100 does not need to be provided with pin holes. Optionally, as shown in Figure 8, the number of slots 180 is one and it is located on the side close to the mating wall 110; optionally, as shown in Figure 9, slot 180 includes a first slot 181 and a second slot 182, the first slot 181 and the second slot 182 are spaced apart along a first direction (the first direction is shown by the arrow in Figure 9). Optionally, as shown in Figure 10, when the corner 52 is inserted into the two connecting structures 100, the corner 52 is completely accommodated in the two connecting structures 100. For example, the extension directions of the two connecting structures 100 form a 90-degree angle, and the edges of the two connecting structures 100 form bevels in the extension direction of the connecting structures 100. The bevels form a 45-degree angle with the third direction. When the two connecting structures 100 are spliced ​​by the corner 52, the two bevels can fit together and make the extension directions of the two connecting structures 100 form a 90-degree angle, and the corner 52 can be completely accommodated in the two connecting structures 100.

[0062] Optionally, as shown in Figure 11, when the corner assemblies 52 are assembled with the two connecting structures 100, a portion of the corner assemblies 52 is contained within the two connecting structures 100, while the other portion of the corner assemblies 52 is located outside the connecting structures 100. For example, in the extending direction of the connecting structures 100, the edges of the two connecting structures 100 are perpendicular to each other. When the two connecting structures 100 are spliced ​​together by the corner assemblies 52, a certain space is formed between the two edges. A portion of the corner assemblies 52 is located in this space and is not contained within the connecting structures 100. Optionally, the connecting frame 50 also includes a corner assemblies sleeve 53, which is fitted over the portion of the corner assemblies 52 that is not contained outside the connecting structures 100, thereby protecting the corner assemblies 52.

[0063] Optionally, a portion of the connecting structure 100 in the connecting frame 50 can be connected to the wall panel 200, thereby reducing the assembly complexity of the composite wall panel assembly 11.

[0064] In some embodiments, each connecting structure 100 in the connecting frame 500 of FIG. 2 is fixedly connected to the wall panel 20 of FIG. 1, thereby further improving the structural strength of the composite wall panel assembly 11; optionally, as shown in FIG. 11, each connecting structure 100 includes a fitting wall 110, the fitting wall 110 extending to form a fitting surface 111, thereby fitting more tightly to the wall panel 20 through a larger area fitting surface 111; optionally, as shown in FIG. 12, the fitting surface 111 forms a fitting cavity 112, the fitting cavity 112 has an opening, and the depth direction of the fitting cavity 112 is perpendicular to a first direction (the first direction is shown by the arrow in FIG. 12), that is, in relation to the wall panel 20 In the assembled state, the opening of the bonding cavity 112 faces the wall panel 20 in Figure 1. The bonding cavity 112 is used to accommodate structural adhesive. The bonding surface 111 is bonded to the wall panel 20 through the structural adhesive. By setting the bonding cavity 112, the bonding surface 111 can accommodate more structural adhesive and concentrate the structural adhesive in the space where the bonding surface 111 contacts the wall panel 20. This allows more structural adhesive to participate in the fixed connection between the bonding surface 111 and the wall panel 20, and also restricts the structural adhesive from being squeezed out of the contact space between the bonding surface 111 and the wall panel 20. This allows the bonding surface 111 to bond more reliably with the wall panel 20, further improving the reliability of the external wall fixing node 10. It should be noted that the bonding surface 111 can form the bonding cavity 112 in different ways. For example, the bonding cavity 112 can be formed by the concavity of the bonding surface 111. For example, the bonding cavity 112 can also be formed by a protruding structure surrounding the bonding surface 111.

[0065] In some embodiments, as shown in FIG13, the connecting structure 100 further includes a separating protrusion 170, which protrudes from the mating surface 111 along a first direction (as indicated by the arrow in FIG13). Multiple separating protrusions 170 are spaced apart, and adjacent separating protrusions 170 and the mating surface 111 surround to form a mating cavity 112. That is, the mating cavity 112 is formed by the protruding structure protruding from the mating surface 111, thereby enabling the formation of the mating cavity 112 without weakening the structural strength of the mating wall 110. At least two separating protrusions 170... Supporting protrusions 171 are formed to abut against the wall panel 20. The supporting protrusions 171 protrude from the mating surface 111 by the same size, which can be understood as the supporting protrusions 171 protruding from the mating surface 111 by the same height. A positioning plane can be defined by two spaced supporting protrusions 171, and the positioning plane is parallel to the mating surface 111. When all supporting protrusions 171 are simultaneously mated with the wall panel 20, the length and width of the wall panel 20 are parallel to the mating surface 111. That is, during the assembly process, the wall panel 20 can be automatically leveled by setting multiple supporting protrusions 171.

[0066] Optionally, as shown in Figure 13, the number of separating protrusions 170 is at least three, and adjacent separating protrusions 170 can form multiple bonding cavities 112. Compared with a large-sized integral bonding cavity 112, dividing the bonding cavity 112 into multiple smaller-sized bonding cavities 112 makes it easier for structural adhesive to fill the bonding cavity 112, thereby bonding the bonding surface 111 to the wall panel 20 more reliably.

[0067] In some embodiments, as shown in FIG14, the filling structure 40 includes an insulation layer 42 and a protective layer 43. The insulation layer 43 is located between the protective layers 42. The insulation layer 42 is configured as a heat insulation material to improve the heat insulation capacity of the exterior wall structure. The protective layer 43 is used to cover the insulation layer 42 to protect it. The insulation layer 42 is located within the space surrounded by the connecting frame 50 in FIG2 and is in contact with the connecting structure 100 that splices together to form the connecting frame 50. Through the partial gravity load of the insulation layer 42 by the connecting structure 100 and the tight wrapping of the insulation layer 42 by the connecting structure 100, the heat insulation material can form a denser insulation layer 42, which not only improves the heat insulation capacity of the insulation layer 42, but also reduces the risk of partial detachment of the insulation layer due to the loose structure of the heat insulation material, further improving the fixing reliability of the insulation layer 40 and the wall panel 20. Optionally, the protective layer 43 also covers the connecting frame 50 to protect the connecting frame 50, thereby improving the structural reliability of the composite wall panel assembly 11.

[0068] In some embodiments, as shown in FIG15, the filling structure 40 further includes an adhesive layer 41 located between the wall panel 20 and the insulation layer 42. The adhesive layer 41 is directly and fixedly connected to both the wall panel 20 and the insulation layer 42. That is, the insulation layer 42 is fixedly connected to the wall panel 20 via the adhesive layer 41. The adhesive layer 41 can be made of a material that is easily fixed to the wall panel 20 and has greater structural strength, such as mortar, adhesive, or a mixture of mortar and adhesive, thereby improving the reliability of the fixation between the insulation layer 42 and the wall panel 20. Optionally, as shown in FIG15, the adhesive layer 41 includes mortar 411 and a metal mesh 412, with the metal mesh 412 and mortar 411 further enhancing the structural strength of the adhesive layer 41.

[0069] In some embodiments, as shown in FIG16, adjacent connecting structures 100 in the connecting frame 50 are fixedly connected by corner brackets 51 in FIG4. Different parts of the corner brackets 51 are fixedly connected to the adjacent connecting structures 100 respectively, so that the adjacent connecting structures 100 can be spliced ​​to form the connecting frame 50. The protective layer 43 covers the connection position between the connecting structure 100 and the corner brackets 51 to protect the corner brackets 51 and improve the structural reliability of the connecting frame 50.

[0070] In some embodiments, as shown in FIG17, the end of the connecting structure 100 away from the wall panel 20 in FIG1 has a hook-shaped portion 194, which surrounds and forms a receiving cavity 195. The opening of the receiving cavity 195 is parallel to the vertical direction, and part of the protective layer 43 is located inside the receiving cavity 195. It can be understood that the support and inner hook applied to the protective layer by the hook-shaped portion 194 can make the bond between the protective layer 43 and the insulation layer 42 tighter, thereby making the structure of the filling layer 40 more reliable.

[0071] In some embodiments, as shown in FIG1, the exterior wall structure includes: a wall 30, a connecting plate 200, and a composite wall panel assembly 11 as shown in any one of FIG2 to FIG17 in the accompanying drawings. The connecting plate 200 is fixedly connected to the composite wall panel assembly 11 and the wall 30 respectively, thereby fixing the composite wall panel assembly 11 to the wall 30.

[0072] In some embodiments, as shown in FIG18, there are multiple connecting plates 200, and multiple connecting plates 200 are simultaneously fixedly connected to the connecting frame 50 in FIG2, so that multiple connecting plates 200 can simultaneously bear the load of the connecting frame 50, thereby improving the structural reliability of the exterior wall structure. It should be noted that the connecting plates 200 may not only be located above or below the connecting frame 50, but may also be located on the side of the connecting frame 50. The connecting plates 200 can be connected to the connecting frame 50 in any way, such as at least one of adhesive bonding, screw connection or slot connection.

Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
