[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] 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 utility model will not be described separately.

[0051] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0052] 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.

[0053] 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 wall panels, tempered glass panels, ceramic tiles, stone slabs, and concrete slabs. The wall panels can be fixed to the wall in a dry-hanging manner, a wet-hanging structure, or a combination of both. Depending on the specific structure of the exterior wall structure, it can be used to achieve various functions. For example, a thermal insulation layer can be used in the exterior wall structure to achieve thermal insulation or heat preservation; a vacuum insulation layer can be used to achieve sound insulation; and wall decorations can be added to the exterior wall structure to enhance its aesthetics. The above structures can also be used in combination to enable the exterior wall structure to achieve multiple functions simultaneously. The following examples, in conjunction with various embodiments, provide exemplary descriptions of different components in the exterior wall structure and the overall structure of the exterior wall structure.

[0054] First, combine Figure 1 The usage environment of the exterior wall structure should be described, such as... Figure 1 As shown, the exterior wall structure includes an exterior wall fixing node 10, wall panels 20, and a wall 30. The wall 30 is the interior wall structure of the building. The wall panels 20 are fixedly connected to the wall 30 through the exterior wall fixing node 10. Multiple wall panels 20 are arranged side by side to cover the wall 30. The exterior wall fixing node 10 includes a connecting structure 100 and a connecting plate 200. The connecting structure 100 is used to fix the wall panels 20, and the connecting plate 200 is used to fix the wall 30. At the same time, the connecting structure 100 and the connecting plate 200 are fixedly connected to fix the wall panels 20 and the wall 30. The structure and function of the connecting structure 100 and the connecting plate 200 in the exterior wall fixing node 10 will be described by way of example in conjunction with various embodiments.

[0055] In some embodiments, such as Figure 2 As shown, the external wall fixing node 10 includes a connecting structure 100 and a connecting plate 200. The connecting plate 200 is connected to the connecting structure. The connecting structure 100 includes a mating wall 110 and an extending wall 120. The outer surface of one side of the mating wall 110 forms a mating surface 111. The extending wall 120 extends from the surface of the mating wall 110 opposite to the mating surface 111, and the extending wall 120 extends along a first direction (the first direction is as follows). Figure 2 (As indicated by the middle arrow) extends, thereby extending the extension wall 120 to a position away from the mating surface 111, thus allowing the extension wall 120 to... Figure 1The connecting plates 200 have a larger assembly space, and the extension wall 120 is used to fit at least part of the connecting plate 200 to fix it to the connecting plate 200. It can be understood that the extension wall 120 extends to form a flat plate structure. By fitting the flat plate extension wall 120 to the connecting plate 200, a larger contact area can be formed, thereby improving the connection reliability between the connecting structure 100 and the connecting plate 200 while reducing the manufacturing cost of the connecting structure 100.

[0056] Optionally, the extension wall 120 and the connecting plate 200 have an adhesive structure, so that the extension wall 120 is fixedly connected to the connecting plate 200 through the adhesive structure, thereby further improving the fixing reliability of the connecting structure 100 and the connecting plate 200.

[0057] This utility model embodiment provides a flat-plate type exterior wall fixing node, which includes a connecting structure and a connecting plate connected to the connecting structure. The connecting structure includes a fitting wall and an extension wall. The fitting wall is used to fit against the wall panel, and the extension wall extends from the fitting wall and extends along a first direction. Moreover, the extension wall is at least partially fitted with the connecting plate. That is, the extension wall extends to form a flat plate structure and is fixedly connected to the connecting plate through the flat plate structure. This increases the contact area between the connecting structure and the connecting plate, thereby reducing the manufacturing cost of the connecting structure and improving the connection reliability between the connecting structure and the connecting plate.

[0058] In some embodiments, such as Figure 3 As shown, the extended wall 120 surrounds and forms a first cavity 141, which is a closed cavity. By creating a vacuum structure within this closed cavity, the first cavity 141 can improve the thermal insulation capacity of the external wall fixed node 10; optionally, as... Figure 3 As shown, the first cavity 141 is filled with thermal insulation material, thereby further improving the thermal insulation capacity of the external wall fixed node 10.

[0059] In some embodiments, such as Figure 4 As shown, the extension wall 120 has a plurality of insertion slots 121, the plurality of insertion slots 121 being along a first direction (the first direction being as shown in the figure). Figure 4 (As indicated by the arrow) The insertion slots 121 are spaced apart and can be formed in any way. For example, the insertion slots 121 are formed by recessing the outer surface of the extension wall 120. For example, the outer surface of the extension wall 120 has a plurality of branch walls 130, and the branch walls 130 and the extension wall 120 surround to form the insertion slots 121. Meanwhile, the connecting plate 200 includes a connecting body 210 and an insertion plate 220. The connecting body 210 is arranged along a first direction (the first direction is as shown by the arrow). Figure 4Extending upwards (as indicated by the middle arrow) and fitting against the extension wall 120, the plug-in plate 220 protrudes from the outer surface of the connecting body 210 and can be inserted into the plug-in slot 121. It can be understood that multiple plug-in slots 121 form multiple installation positions for the connecting plate 20 in the first direction. By inserting the plug-in plate 220 into different plug-in slots 121, the external wall fixing node 10 can have different dimensions in the first direction. That is, the dimension of the external wall fixing node 10 in the first direction can be adjusted. When the external wall fixing node 10 is assembled into the external wall structure, the first direction is the distance between the wall and the wall panel in the external wall structure. By adjusting the dimension of the external wall fixing node 10 in the first direction, the external wall fixing node 10 can be adapted to different distances between the external wall and the wall, thus improving the versatility of the external wall fixing node 10. Furthermore, by inserting the plug plate 220 into the plug slot 121, the connection structure 100 can not only transmit torque to the connection plate 200 but also apply tensile stress to the connection plate 200. At this time, the connection plate 200 mainly bears the bending moment. Under the action of the bending moment, one side of the connection plate 200 is under tension and the other side is under compression. The tensile capacity of the tough material is greater than its compressive capacity, and the stress on the compression side of the connection plate 200 can be offset by the tensile stress. The stress on the tension side of the connection plate 200 is superimposed with the tensile stress. That is, the tensile effect of the connection plate 200 is enhanced and the tensile effect is weakened. Since the connection plate 200 is generally made of tough material, such as metal, the stress state of the connection plate 200 is optimized by the tensile stress, thereby making better use of the tensile capacity of the connection plate 200, so that the wall panel 20 can be more reliably fixedly connected to the wall 30, that is, the reliability of the fixed node is improved.

[0060] In some embodiments, such as Figure 5 As shown, the extension wall 120 includes an extension body 122 and branch walls 123. The extension body 122 extends along a first direction and is used to fit against the connecting body 210. The branch walls 123 protrude from the outer surface of the extension body 122, and a plurality of branch walls 123 extend along the first direction (the first direction is as follows). Figure 5 (As indicated by the middle arrow) The branches are spaced apart, so that the outer surfaces of adjacent branch walls 123 and extension bodies 122 surround and form multiple insertion slots 121. By forming the insertion slots 121 around the branch walls 123, the insertion slot 121 structure can be formed without cutting the extension wall 120, thereby improving the structural strength of the extension wall 120 while still enabling dimensional adjustment of the external wall connection node 10. It should be noted that, as... Figure 5 As shown, while the extension body 120 extends through the branch wall 123 to form the insertion groove 121, the extension wall 120 can also surround and form the first cavity 141, thereby forming a more stable insertion structure and improving the thermal insulation capacity of the external wall fixing structure 10 through the first cavity 141.

[0061] In some embodiments, such as Figure 5 As shown, there is an adhesive material between the inner walls of the plug plate 220 and the plug groove 121. This can be understood as follows: while the connecting body 210 is in contact with the extension wall 120, the contact area between the connecting structure 100 and the connecting plate 200 can be further increased by the cooperation of the plug plate 220 and the plug groove 121. At the same time, by providing adhesive material between the inner wall of the plug groove 121 and the plug plate 220, the plug plate 200 and the plug groove 121 can be more reliably fixed together.

[0062] In some embodiments, such as Figure 6 As shown, the mating surface 111 forms a mating cavity 112, the mating cavity 112 has an opening, and the depth direction of the mating cavity 112 is perpendicular to the first direction (the first direction is as shown in the figure). Figure 6 (As indicated by the middle arrow), that is, in the state of being assembled with the wall panel 20, the opening of the fitting cavity 112 faces... Figure 1 In the wall panel 20, 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 prevents 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.

[0063] In some embodiments, such as Figure 7 As 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 7(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.

[0064] In some embodiments, such as Figure 8 As shown, the mating wall 110 extends along the second direction (the second direction is as follows). Figure 8 (As shown by the dashed arrow in the middle), the second direction is not the same as the first direction (the first direction is as shown by the dashed arrow in the middle). Figure 8 (As indicated by the solid arrow in the middle) Parallel, wherein, in the second direction, the bonding wall 110 extends from one side of the extension wall 120 to the other side, that is, the bonding wall 110 crosses the extension wall 120 in the second direction, thereby enabling the bonding wall 110 to form a bonding cavity 112 with a larger size in the second direction, thereby enabling the bonding cavity 112 to accommodate more structural adhesive and enabling the connection structure 100 to be bonded to the wall panel within a larger size range, further improving the fixing reliability of the connection structure 100 and the wall panel.

[0065] In some embodiments, such as Figure 9 As shown, in the second direction (the second direction is as follows) Figure 9 As indicated by the middle arrow, the fitting wall 110 is located on one side of the extension wall 120, and one end of the fitting wall 110 is flush with the outer surface of the extension wall 120. During the assembly process, the fitting wall 110 is positioned on the side away from the connecting plate 200, so that the connecting structure 100 can be moved to a position closer to the connecting plate 200. When this external wall connecting structure 10 is applied to the external wall structure, the adjacent connecting structures 100 are brought closer together, so that the spacing between the adjacent connecting structures 100 can be adjusted within a wider range, thereby allowing for more free adjustment of the size of the wall joint.

[0066] In some embodiments, such as Figure 10 As shown, in the second direction (the second direction is as follows) Figure 10As shown by the middle arrow, the two sides of the fitting wall 110 and the extension wall 120 are flush. This can be understood as the extension wall 120 forming two edges in the second direction, and the fitting wall 110 being flush with the two edges respectively. This makes the structure of the connecting structure 100 more compact. Moreover, when it is necessary to splice the connecting structure 100 to form a connecting frame, the structure with both ends flush can stably support the connecting structure 100 on the automatic corner assembly device, thereby facilitating the automatic corner assembly of the connecting structure 100.

[0067] In some embodiments, such as Figure 11 As shown, the mating wall 110 and the extending wall 120 are along a third direction (the third direction is as follows). Figure 11 Extending from the midpoint line, the third direction is perpendicular to the first direction (the first direction is as follows). Figure 11 (as shown by the solid arrow in the middle), and the third direction is perpendicular to the second direction (as shown by the second direction). Figure 10 (as shown by the dashed arrow in the middle) Figure 12 As shown, multiple connecting structures 100 are spliced ​​together to form a connecting frame 50, which encloses and forms a closed shape. The connecting frame 50 is fixed to... Figure 1 One side of the wall panel 20 forms the overall structure of the wall panel frame. Simultaneously, the connecting frame 50 is fixedly connected to multiple connecting plates 200. This can be understood as the wall panel frame structure connecting the connecting plates 200 in multiple external wall fixing nodes 10 into a whole. The localized force on the wall panel 20 can be transferred to the multiple external wall fixing nodes 10 through the connecting frame 50, thereby increasing the structural strength of the external wall structure through the joint bearing of the external force by the multiple external wall fixing nodes 10. It should be noted that multiple connecting structures 100 can be spliced ​​together to form the connecting frame 50 in any way. For example, multiple connecting structures 100 can be directly spliced ​​together by welding to form the connecting frame 50, or multiple connecting structures 100 can be interconnected by connectors to form the connecting frame 50. The following will combine... Figures 13 to 15 Two methods of splicing to form the connecting frame 50 are given respectively. Those skilled in the art should understand that multiple connecting structures 100 can also be spliced ​​to form the connecting frame 50 in other ways. Figures 13 to 15 Other methods are shown.

[0068] like Figure 13 As shown, adjacent connecting structures 100 in the connecting frame 50 are fixedly connected by corner brackets 51. Corner brackets 51 are sheet-like structures comprising two parts, with the extending directions of the two parts forming a certain angle, such as 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 extending directions of the two connecting structures 100 (which can be understood as...) Figure 10The third direction of the connecting structure 100 in the middle forms a target included angle, and multiple connecting structures 100 are connected end to end by multiple corner codes 51 so that multiple connecting structures can be spliced ​​together to form a connecting frame 50.

[0069] Optional, such as Figure 13 As 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 11 (As shown by the solid arrow in the middle) the end of the connecting structure 100 away from the mating wall 110, the end of the mating wall 110 is used to connect with... Figure 1 If the corner bracket 51 is placed near the end of the mating wall 110, it may cause assembly interference between the corner bracket 51 and the wall panel 20. Placing the corner bracket 51 away from the end of the wall panel 20 can reduce the risk of motion interference between the corner bracket 51 and the wall panel 20.

[0070] Optional, such as Figure 14 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 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 192 or a positioning protrusion, or one part can be a positioning groove and the other part can be a positioning protrusion.

[0071] like Figure 15As 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 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. It should be noted that the slots for inserting corner brackets 52 can be additionally provided slot structures, or slots can be formed using the first cavity 141. 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 by corner brackets 52 at the ends with the first cavity 141, and are fixedly connected by corner brackets 51 at the ends without the first cavity 141. 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 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, 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 of the connecting structure 100 form an interference fit by simultaneously extruding the corner assembly 52 into the slots of two adjacent connecting structures 100, and the connecting structure 100 does not need to be provided with pin holes.

[0072] In some embodiments, such as Figure 2 As shown, the connecting structure 100 is an integral structure and is made of metal material, thereby improving the structural strength of the connecting structure 100.

[0073] In some embodiments, such as Figure 16 As shown, the connection structure 100 includes a first part 151 and a second part 152. The first part 151 includes a fitting wall 110 and a portion of an extension wall 120. The first part 151 is used for fixed connection with the wall panel. The second part 152 includes the other part of the extension wall 120. The first part 151 and the second part 152 are aligned along a first direction (the first direction is as follows). Figure 16 As shown by the middle arrow, the first part 151 and the second part 152 are arranged in sequence and are detachably connected. It can be understood that by setting the connection structure 100 as a split structure, the two parts can be made of different materials according to their functions and loads, thereby reducing the manufacturing cost of the connection structure 100.

[0074] In some embodiments, such as Figure 17As shown, the extension wall 120 of the first part 151 forms a plug groove 121. It can be understood that the first part 151 is fixedly connected to the connecting plate 200 through the plug groove 121. The first part 151 is the main load-bearing part. In this state, the first part 151 is made of metal material and the second part 152 is made of polymer material such as injected plastic, which can reduce the manufacturing cost of the connecting structure 100.

[0075] In some embodiments, such as Figure 18 As shown, the extended wall of the second part 152 surrounds and forms the second cavity 142, and the second cavity 142 is a closed cavity, thereby further improving the heat insulation capability of the connecting structure 100. Optionally, such as Figure 19 As shown, the extended wall of the first part 151 surrounds and forms the third cavity 143, and the third cavity 143 is a closed cavity, thereby further improving the heat insulation capability of the connecting structure 100.

[0076] This utility model embodiment also provides an exterior wall structure, which applies the exterior wall fixing nodes provided in the above embodiment. The structure and function of the exterior wall structure will be described by way of example below with reference to the embodiment.

[0077] In some embodiments, such as Figure 1 As shown, the exterior wall structure includes: exterior wall fixing node 10, wall panel 20, and wall body 30. The structure of the exterior wall fixing node 10 is shown in the attached diagram of the specification. Figures 2 to 18 As shown in any of the diagrams, wall panel 20 is bonded to mating surface 111, and wall body 30 is fixedly connected to the second end of connecting body 210. This can be understood as wall panel 20 being fixedly connected to connecting structure 100, connecting plate 200 being fixedly connected to connecting structure 100, and wall body 30 being fixedly connected to connecting plate 200, thus fixing wall panel 20 and wall body 30 together. Vertically, two connecting structures 100 are fixedly connected to adjacent wall panels 20, and the first end of connecting body 210 is located between the two adjacent wall panels 20. An adhesive structure exists between the two adjacent wall panels 20. This can be understood as an external wall fixing node 10 used to simultaneously fix two vertically adjacent wall panels 20. Simultaneously, the two wall panels 20 are connected to each other through a filling adhesive structure to improve the fixing reliability between the two wall panels 20. If this adhesive structure is set as a heat insulation material, it can also improve the heat insulation effect of the external wall structure. The adhesive structure can be a structure formed by filling the space between wall panels 20 with fixing adhesive, or it can be a fixing block with adhesive properties. Optionally, the first end of the connecting body 210 may not extend between two adjacent wall panels 20. In this state, the adhesive between the two wall panels 20 can be fixed to the first end, or the adhesive may not contact the first end; optionally, such as Figure 1As shown, the first end of the connecting body 210 extends between two adjacent wall panels 20 and is connected to the adhesive between the two wall panels 20. The connection between the connecting body 210 and the adhesive can improve the structural strength of the exterior wall structure. The part of the connecting body 210 extending between the two wall panels 20 can also provide a certain degree of support for the upper wall panel 20, thereby further improving the strength of the exterior wall structure. Moreover, by squeezing the adhesive through the connecting body 210, the adhesive can be made to fill the space between the two wall panels 20 more fully, which not only makes the fixation between the two wall panels 20 more reliable but also reduces the amount of adhesive used.

[0078] At the same time, such as Figure 20 As shown, the exterior wall structure also includes an infill layer 40, which is close to the wall panel 20. Figure 1 The wall 30 is fixedly connected to one side. Depending on the material of the filling layer 40, different functions can be achieved. For example, when the filling layer 40 includes thermal insulation material, the filling layer 40 can improve the thermal insulation capacity of the exterior wall structure. For example, when the filling layer 40 includes sound insulation sponge material, the filling layer 40 can improve the sound insulation capacity of the exterior wall structure. For example, when the filling layer 40 includes mortar and metal mesh, the filling layer 40 can improve the structural strength of the wall panel 20, thereby improving the overall structural strength of the exterior wall structure.

[0079] Optional, such as Figure 20 As shown, the filling layer 40 includes: an insulation layer 42 and a protective layer 43, extending from the wall panel 20 towards... Figure 1 In the direction of the wall 30, the insulation layer 42 and the protective layer 43 are arranged in sequence, thereby fixing the filling layer 40 to the side of the wall panel 20 close to the wall 30. The insulation layer 42 is set as a heat insulation material to improve the heat insulation capacity of the external wall structure, and the protective layer 43 is used to cover the insulation layer 42 to protect the insulation layer.

[0080] Optional, such as Figure 21 As shown, the filler layer 40 also includes an adhesive layer 41, extending from the wall panel 20 towards... Figure 1 In the direction of the wall 30, the adhesive layer 41 is located between the insulation layer 42 and the wall panel 20, and the adhesive layer 41 is directly fixed to the side of the wall panel 20 closest to the wall 30 to improve the fixing strength between the insulation layer 42 and the wall panel 20. The materials of the adhesive layer 41 and the protective layer 43 are mortar, adhesive, or a mixture of mortar and adhesive; optionally, such as... Figure 21 As shown, the adhesive layer 41 includes mortar 411 and metal mesh 412, with the metal mesh 412 and mortar 411 used to improve the structural strength of the adhesive layer 41.

Although this utility model 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 utility model without departing from the spirit and scope of the technical solutions of this utility model.
