[0047] Here, it also needs to be explained that, in order to avoid the utility model being obscured by unnecessary details, only the structures and / or processing steps closely related to the scheme of the utility model are shown in the drawings, and other details not closely related to the utility model are omitted.

[0048] It should also be noted that the terms "comprising", "including", or any other variant thereof are intended to cover a non-exclusive inclusion, such that processes, methods, articles, or apparatuses that comprise a list of elements are not limited to those elements, but can include other elements not expressly listed or inherent to such processes, methods, articles, or apparatuses. In the following description, the terms "first", "second", and the like are used only to distinguish different objects, and do not indicate the same or related objects. It should be understood that the orientation of the terms "upper", "lower", "inner", "outer", and the like described by the orientation terms represent the orientation in the normal use state.

[0049] In the following detailed description, the wall panels in the outer wall structure can be any material, for example, the wall panels can be one or a combination of metal panels, tempered glass panels, ceramic tiles, stone panels, and concrete panels. The wall panels can be fixed to the wall body in a dry hanging manner, in a wet hanging structure, or in a combination of dry hanging and wet hanging. Depending on the specific structure of the outer wall structure, the outer wall structure can be used to achieve various functions, for example, the outer wall structure can be used with a thermal insulation filling layer to achieve thermal insulation or heat preservation, the outer wall structure can be used with a vacuum insulation layer to achieve sound insulation, the outer wall structure can be used with wall decoration elements to improve the aesthetics of the building, and the above structures can be combined to achieve multiple functions simultaneously. The different components in the outer wall structure and the overall structure of the outer wall structure will be described in the following embodiments.

[0050] First, the outer wall structure is described as shown in Figure 1 The use environment of the outer wall structure is described as shown in Figure 1 The outer wall structure includes an outer wall fixing node 10, wall panels 20, and a wall body 30. The wall body 30 is the inner wall structure of a building, the wall panels 20 are fixedly connected to the wall body 30 through the outer wall fixing node 10, and multiple wall panels 20 are arranged side by side to cover the wall body 30. The outer wall fixing node 10 includes a connecting frame 50 and a connecting plate 200. The connecting frame 50 is used to fixedly connect with the wall panels 20, and the connecting plate 200 is used to fixedly connect with the wall body 30. At the same time, the connecting frame 50 and the connecting plate 200 are fixedly connected to fixedly connect the wall panels 20 and the wall body 30. The wall panels 20 and part of the structure in the outer wall fixing node 10 are combined to form a composite wall panel assembly 11. The structure of the composite wall panel assembly 11 will be described in the following embodiments.

[0051] In some embodiments, as shown in Figure 2As shown, the composite wallboard assembly 11 comprises a wallboard 20, a connecting frame 50 and a filling structure 40. The connecting frame 50 surrounds a closed figure and is fixed to a first wall surface of the wallboard 20, which is one of the length-width surfaces of the wallboard 20 and faces the wall 30 in the assembled state. It can be understood that the connecting frame 50 forms a frame structure at one of the length-width surfaces of the wallboard 20 and surrounds a containing space by connecting the head and tail. The connecting frame 50 can be an integrally formed structure or formed by splicing multiple parts.

[0052] The filling structure 40 is fixed to the first wall surface of the wallboard 20 and partially contained in the space surrounded by the connecting frame 50, and the filling structure 40 in the space is in contact with the connecting frame 50. It can be understood that the filling structure 40 and the connecting frame 50 are fixed to the same side of the wallboard 20, and the connecting frame 50 surrounds and contacts the filling structure 40, so that the connecting frame 50 can bear part of the gravity of the filling structure 40. In the case that the filling structure 40 is formed of loose material, the connecting frame 50 can also function to tightly wrap the loose material, thereby reducing the risk of partial shedding of the filling structure 40 due to excessively loose structure, and further improving the fixing reliability of the filling structure 40 and the wallboard 20. The filling structure 40 can be any structure having a heat preservation function. For example, the filling structure 40 comprises a heat insulation layer formed of heat insulation material, and the filling structure 40 comprises a plurality of heat insulation plates and a vacuum cavity formed between adjacent heat insulation plates.

[0053] Optionally, in the outer wall structure, the connecting frame 50 is used to be fixedly connected with the plurality of fixed plates 200 at the same time, so that the load borne by the wallboard 20 can be transmitted to the plurality of fixed plates 200 at the same time, thereby reducing the load size of a single fixed plate 200 and improving the overall structural strength of the outer wall structure. Figure 1

[0054] The embodiment of the utility model provides a composite wallboard assembly, the composite wallboard assembly comprises: a wallboard, a connecting frame fixed to a first wall surface of the wallboard and surrounding a closed figure, and a filling structure having a heat preservation function, part of the filling structure is contained in a space surrounded by the connecting frame and the filling structure in the space is in contact with the connecting frame, so that the connecting frame can bear part of the gravity of the filling structure, in the case that the filling structure is formed of loose material, the connecting frame can also function to tightly wrap the loose material, thereby reducing the risk of partial shedding of the filling structure due to excessively loose structure, and further improving the fixing reliability of the filling structure and the wallboard.

[0055] In some embodiments, as Figure 2 ​As shown, the connection frame 50 encloses a rectangular closed figure, and the connection frame 50 is fixedly connected with the fixed plates 200 in the four adjacent outer wall fixed nodes 10. It can be understood that the wall plate 20 is generally a cube, and the plurality of outer wall fixed nodes 10 are arranged at intervals around the outer edge of the wall plate 20, so that the outer wall fixed nodes 10 are arranged along the rectangle, and the closed figure enclosed by the connection frame 50 is set as a rectangle, so that the extension direction of the connection frame 50 is adapted to the arrangement direction of the outer wall fixed nodes 10, thereby facilitating the fixed connection of the connection frame 50 and the outer wall fixed nodes 10. It should be noted that, according to the shape of the wall plate 20, the closed figure enclosed by the connection frame 50 can also be adaptively changed. For example, when the wall plate 20 is a hexagonal prism, the closed figure enclosed by the connection frame 50 is a hexagon.

[0056] In some embodiments, as shown in Figure 2 The connection frame 50 is an integral structure, which can improve the structural strength of the connection frame 50. The integral structure can be obtained by integral molding. For example, the connection frame 50 is integrally molded by casting or forging. The integral structure can also be processed by different detachable fixing modes. For example, the connection frame 50 includes a plurality of parts, and the parts are fixedly connected by welding to form an integral connection frame 50.

[0057] In some embodiments, as shown in Figure 3 The connection frame 50 includes a plurality of connection structures 100. The structure of each connection structure 100 can be any structure that can be spliced to form the connection frame 50. In various embodiments, the shape of the connection structure 100 is not limited. The connection structures 100 are assembled at certain positions by the connection structure to obtain a spliced connection frame 50, thereby reducing the manufacturing difficulty and cost of the connection frame 50. The splicing method of the connection frame 50 by the connection structure 100 will be described below in conjunction with various embodiments.

[0058] In some embodiments, as shown in Figure 4 The adjacent connection structures 100 in the connection frame 50 are fixedly connected by the corner code 51. The corner code 51 is a sheet structure including two parts with a certain included angle between the extension directions of the two parts. For example, the included angle can be a right angle. The two parts of the corner code 51 are fixedly connected with the outer surfaces of the two connection structures 100, so as to fixedly connect the two connection structures 100 and form a target included angle between the extension directions of the two connection structures 100. The plurality of connection structures 100 are connected end to end by the plurality of corner codes 51, so as to splice the plurality of connection structures to form the connection frame 50.

[0059] Optionally, as shown in Figure 4As shown, the positioning end in the connection structure 100 is fixedly connected by the corner bracket 51, and this positioning end is in the first direction (the first direction is as shown in the figure). Figure 4 As shown by the solid arrow in the middle, at the end of the connecting structure 100 away from the wall panel 20, 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.

[0060] Optional, such as Figure 5 As shown, 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 capable of holding the corner bracket 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 following will be combined with Figure 5 to Figure 7 The structure of positioning structure 191 is illustrated by way of example.

[0061] like Figure 5 As shown, the positioning structure 191 includes a positioning cavity 192, which extends from the positioning end along a first direction (the first direction is as shown in the figure). Figure 5 As indicated by the middle arrow, the positioning cavity 192 is recessed and used to accommodate at least a portion of the corner bracket 51. This can be understood as the positioning cavity 192 having an opening facing a first direction. Inserting the corner bracket 51 into the positioning cavity 192 through this opening along the first direction allows the corner bracket 51 to abut against the inner wall of the positioning cavity 192, thereby positioning the corner bracket 51 at the target position. Optionally, the positioning ends of adjacent connecting structures 100 in the connecting frame 50 each form a positioning cavity 192. The positioning cavities 192 of the two connecting structures 100 are connected and form the same shape as the corner bracket 51 perpendicular to the thickness direction, thus allowing the positioning cavities 192 of the two splicing structures 100 to be spliced ​​together to form a cavity for accommodating the corner bracket 51.

[0062] like Figure 6As shown, the positioning structure 191 includes a positioning protrusion 193 protruding from the positioning end along a first direction (the first direction is indicated by the solid arrow in Figure 6 The positioning protrusion 193 is in abutment with the corner code 51 in a direction perpendicular to the first direction. It can be understood that the corner code 51 is in abutment with the positioning end to limit the movement of the corner code 51 relative to the connecting structure 100 in the first direction, and the movement of the corner code 51 relative to the connecting structure 100 in a direction perpendicular to the first direction is limited by the positioning protrusion 193, so that the corner code 51 can 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 is in abutment with the positioning protrusion 193 in a direction perpendicular to the first direction. For example, the corner code 51 approaches the positioning protrusion 193 along a direction perpendicular to the first direction after approaching the positioning end and is in abutment with the positioning protrusion 193.

[0063] Optionally, as shown in Figure 6 The corner code 51 includes a first connecting portion 511 and a second connecting portion 512. The first connecting portion 511 and the second connecting portion 512 form a first included angle between the extension directions thereof. For example, the first included angle can be 90 degrees. The first portion 511 and the second portion 512 are connected to two adjacent connecting structures 100 in the connecting frame 50, respectively, so that the connecting structures 100 can be spliced to form the connecting frame 50. Meanwhile, the positioning protrusions 193 of the two adjacent connecting structures 100 in the connecting frame 50 are in abutment with the first connecting portion 511 and the second connecting portion 512, respectively. The extension directions of the two positioning protrusions 193 form a first included angle. It can be understood that the two adjacent connecting structures 100 form a protrusion structure having the same shape as the corner code 51 in a direction perpendicular to the thickness direction. The two connecting protrusions 193 can be in abutment with the two connecting portions of the corner code 51 in two orthogonal directions (for example, a second direction and a third direction) perpendicular to the first direction, respectively, so as to limit the movement of the corner code 51 relative to the connecting structure 100 in the above two orthogonal directions, respectively. That is, by simplifying the structure of the connecting protrusion 193 of a single connecting structure 100, the manufacturing cost of the connecting structure 100 is reduced.

[0064] Optionally, as shown in Figure 7 The connecting structure 100 has a plurality of positioning protrusions 193. The positioning protrusions 193 are arranged at intervals along a second direction (the second direction is indicated by the dashed arrow in Figure 7 The adjacent positioning protrusions 193 surround a positioning space. The inner wall of the positioning space is used to abut against the corner code 51. It can be understood that the positioning space has a first direction (the first direction is indicated by the solid arrow in Figure 7In the first direction (the first direction is indicated by the solid arrow in FIG. 6), the positioning protrusion 193 has a first guide surface 194. In the second direction (the second direction is indicated by the dashed arrow in FIG. 6), the first guide surface 194 is located on the side close to the corner code 51. It can be understood that, in the process of moving the corner code 51 close to the positioning protrusion 193 in the first direction, the corner code 51 can abut against the first guide surface 194. In the direction in which the positioning end of the positioning protrusion 193 extends, the cross-sectional area of the positioning protrusion 193 decreases. The cross section is a plane perpendicular to the extension direction of the positioning protrusion 193. In the process of moving the corner code 51 close to the positioning protrusion 193 in the first direction, the first guide surface 194 can move the corner code 51 close to the target position. In the process of automatically assembling the corner code 51 and the connecting structure 100, the moving structure can position the corner code 51 to the target position with the aid of the first guide surface 194.

[0065] Optionally, as shown in FIG. 6, in the first direction (the first direction is indicated by the solid arrow in FIG. 6), the positioning protrusion 193 has a first guide surface 194. In the second direction (the second direction is indicated by the dashed arrow in FIG. 6), the first guide surface 194 is located on the side close to the corner code 51. It can be understood that, in the process of moving the corner code 51 close to the positioning protrusion 193 in the first direction, the corner code 51 can abut against the first guide surface 194. In the direction in which the positioning end of the positioning protrusion 193 extends, the cross-sectional area of the positioning protrusion 193 decreases. The cross section is a plane perpendicular to the extension direction of the positioning protrusion 193. In the process of moving the corner code 51 close to the positioning protrusion 193 in the first direction, the first guide surface 194 can move the corner code 51 close to the target position. In the process of automatically assembling the corner code 51 and the connecting structure 100, the moving structure can position the corner code 51 to the target position with the aid of the first guide surface 194. Figure 7 Figure 7 Figure 7

[0066] Optionally, the first connecting part 511 and the second connecting part 512 of the corner code 51 each have a connecting hole. The number of the connecting holes of the first connecting part 511 and the second connecting part 512 is at least one. Multiple connecting holes can facilitate the leveling of the corner code 51. A single connecting hole can make the corner code 51 more quickly assembled with the connecting structure 100.

[0067] As shown in FIG. 6, the first connecting part 511 and the second connecting part 512 of the corner code 51 are arranged in the connecting frame 50. Figure 8 ​​​As shown, adjacent connecting structures 100 in the connecting frame 50 are fixedly connected by corner brackets 52. 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 corner brackets 52 into the slots 180 of the connecting structure 100, and then fixing 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 the ends with insertion cavities using corner brackets 52, and at the 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 using connecting pins. Specifically, a clearance fit or overfit is formed between the corner assembly 52 and the slot 180 of the connecting structure 100, and pin holes are 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 using pins. Alternatively, the corner assembly 52 can also be fixedly connected to the connecting structure 100 by compression. Specifically, the corner assembly 52 and the slot 180 of the connecting structure 100 form an interference fit by simultaneously squeezing the corner assembly 52 into the slots 180 of two adjacent connecting structures 100, and the connecting structure 100 does not need to have pin holes. Optionally, such as... Figure 8 As shown, the number of slots 180 is one and it is located on the side close to the mating wall 110; optionally, as Figure 9 As shown, slot 180 includes a first slot 181 and a second slot 182, the first slot 181 and the second slot 182 being along a first direction (the first direction is as follows). Figure 9 (Indicated by the middle arrow) Interval setting. Optional, such as... Figure 10 As shown, with the corner 52 inserted into the two connecting structures 100, the corner 52 is completely contained within the two connecting structures 100. For example, the extending directions of the two connecting structures 100 form a 90-degree angle. In the extending direction of the connecting structures 100, the edges of the two connecting structures 100 form bevels, which form a 45-degree angle with the third direction. When the two connecting structures 100 are spliced ​​together by the corner 52, the two bevels can fit together and make the extending directions of the two connecting structures 100 form a 90-degree angle, and the corner 52 can be completely contained within the two connecting structures 100.

[0068] Optional, such as Figure 11As shown, in the assembled state of the corner 52 and the two connecting structures 100, part of the corner 52 is accommodated in the two connecting structures 100, and the other part of the corner 52 is located outside the connecting structures 100. For example, the edges of the two connecting structures 100 are perpendicular to each other in the extension direction of the connecting structures 100, and when the two connecting structures 100 are spliced by the corner 52, a space is formed between the two edges, and part of the corner 52 is located in the space and thus not accommodated in the connecting structures 100. Optionally, the connecting frame 50 further comprises a corner sleeve 53, which is sleeved on the part of the corner 52 that is not accommodated in the connecting structures 100, so as to protect the corner 52.

[0069] Optionally, part of the connecting structures 100 in the connecting structures in the connecting frame 50 are connected with the wallboard 200, so as to reduce the assembly complexity of the composite wallboard assembly 11.

[0070] In some embodiments, Figure 2 the connecting structures 100 in the connecting frame 500 are fixedly connected with Figure 1 the wallboard 20, so as to further improve the structural strength of the composite wallboard assembly 11; optionally, as shown in Figure 11 each connecting structure 100 comprises a fitting wall 110, and the fitting wall 110 extends to form a fitting surface 111, so that the fitting surface 111 is more closely fitted with the wallboard 20 through a larger area; optionally, as shown in Figure 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 the first direction (the first direction is shown by the arrow in Figure 12 in the assembled state with the wallboard 20, the opening of the fitting cavity 112 faces Figure 1 the wallboard 20 in the composite wallboard assembly 11, and the fitting cavity 112 is used to accommodate structural glue, and the fitting surface 111 is fitted with the wallboard 20 through the structural glue. By providing the fitting cavity 112, the fitting surface 111 can accommodate more structural glue and gather the structural glue in the space where the fitting surface 111 contacts the wallboard 20, so that more structural glue can participate in the fixed connection of the fitting surface 111 and the wallboard 20, and the structural glue can be limited from being squeezed out of the contact space between the fitting surface 111 and the wallboard 20, so that the fitting surface 111 can be more reliably fitted with the wallboard 20, and the reliability of the outer wall fixed node 10 is further improved. It should be noted that the fitting surface 111 can form the fitting cavity 112 in different ways. For example, the fitting cavity 112 can be formed by being concave in the fitting surface 111, and the fitting cavity 112 can also be formed by being surrounded by a protruding structure protruding from the fitting surface 111.

[0071] In some embodiments, as shown in Figure 13As shown, the connecting structure 100 also includes a separating protrusion 170, the separating protrusion 170 being along a first direction (the first direction is as shown in the figure). Figure 13 (As indicated by the middle arrow) protruding from the mating surface 111, wherein multiple separating protrusions 170 are spaced apart, and adjacent separating protrusions 170 and 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 forming the mating cavity 112 without weakening the structural strength of the mating wall 110; wherein at least two separating protrusions 170 form a supporting protrusion 171, the supporting protrusion 171 being used to abut against the wall panel 20. The support protrusions 171 protrude from the mating surface 111 at the same size, which can be understood as the support protrusions 171 protruding from the mating surface 111 at the same height. A positioning plane can be defined by two spaced support protrusions 171, and this positioning plane is parallel to the mating surface 111. When all support 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 support protrusions 171.

[0072] Optional, such as Figure 13 As shown, there are at least three separating protrusions 170. Adjacent separating protrusions 170 can form multiple bonding cavities 112. Compared to a large integral bonding cavity 112, dividing the bonding cavity 112 into multiple smaller bonding cavities 112 makes it easier for the structural adhesive to fill the bonding cavity 112, thereby bonding the bonding surface 111 to the wall panel 20 more reliably.

[0073] In some embodiments, such as Figure 14 As shown, 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 between the insulation layer 42 and the protective layer 43. Figure 2 Within the space enclosed by the connecting frame 50 and in contact with the connecting structure 100 that forms the connecting frame 50, the insulation layer 42 is partially supported by the gravity load of the connecting structure 100, and the insulation layer 42 is tightly wrapped by the connecting structure 100. This allows the insulation material to form a denser insulation layer 42, which not only improves the 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 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.

[0074] In some embodiments, such as Figure 15As shown, the filling structure 40 further comprises a bonding layer 41, which is located between the wallboard 20 and the thermal insulation layer 42, and is fixedly connected with the wallboard 20 and the thermal insulation layer 42, i.e., the thermal insulation layer 42 is fixedly connected with the wallboard 20 through the bonding layer 41. The bonding layer 41 can be made of a material that can be easily fixed with the wallboard 20 and has greater structural strength, such as mortar or glue or a mixture of mortar and glue, so as to improve the fixing reliability of the thermal insulation layer 42 with the wallboard 20. Optionally, as shown in Figure 15 The bonding layer 41 comprises mortar 411 and metal mesh 412, which are used to improve the structural strength of the bonding layer 41.

[0075] In some embodiments, as shown in Figure 16 The adjacent connecting structures 100 in the connecting frame 50 are fixedly connected through the corner code 51 in Figure 4 The different parts of the corner code 51 are fixedly connected with 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 of the connecting structure 100 and the corner code 51, so as to protect the corner code 51 and improve the structural reliability of the connecting frame 50.

[0076] In some embodiments, as shown in Figure 17 The end of the connecting structure 100 away from the wallboard 20 in Figure 1 has a hook-shaped part 194, which surrounds a receiving cavity 195, the opening of which is parallel to the vertical direction. Part of the protective layer 43 is located in the receiving cavity 195. It can be understood that the support and inner hook of the protective layer 43 provided by the hook-shaped part 194 can make the combination of the protective layer 43 and the thermal insulation layer 42 more closely, so as to make the structure of the filling layer 40 more reliable.

[0077] In some embodiments, as shown in Figure 1 The outer wall structure comprises a wall body 30, a connecting plate 200, and a composite wallboard assembly 11 as shown in any one of the accompanying drawings. Figure 2 to Figure 17 The connecting plate 200 is fixedly connected with the composite wallboard assembly 11 and the wall body 30 respectively, so as to fixedly connect the composite wallboard assembly 11 and the wall body 30.

[0078] In some embodiments, as shown in Figure 18 The number of the connecting plate 200 is plural, and the plural connecting plates 200 are simultaneously fixedly connected with Figure 2The connecting frame 50 in the connecting plate 200 is fixedly connected, so that the plurality of connecting plates 200 can simultaneously bear the load of the connecting frame 50, and the structural reliability of the outer wall structure is improved; it should be noted that the connecting plate 200 can not only be located above or below the connecting frame 50, but also can be located on the side of the connecting frame 50; the connecting plate 200 can be connected with the connecting frame 50 in any way, for example, the connecting mode can be at least one of bonding, screw connection or through a slot connection.
