This ensures that while the mating surfaces of the two extended frames are mated together, the included angle between the mating surfaces of the two extended frames is the same as the target included angle. After the two wall panels are mated with the two mating surfaces, the included angle between the two wall panels is the same as the included angle of the wall at the corner, which improves the flatness of the exterior wall structure at the corner.

Detailed Implementation

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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 are fixed to the wall in a dry-hanging manner, that is, the wall panels and the wall are spaced far apart, so there is no adhesive structure between the wall panels and the wall. Depending on the specific structure of the exterior wall structure, the exterior wall structure 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; 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, so that the exterior wall structure can achieve multiple functions simultaneously. The following describes the different components in the exterior wall structure and the overall structure of the exterior wall structure by way of example, with reference to various embodiments.

[0053] First, combine Figure 1 Describe the usage environment of the exterior wall structure, such as Figure 1 As shown, the exterior wall structure includes a fixed node 10, wall panels 20, and a wall 30. The wall 30 is the building's interior wall structure. The wall panels 20 are fixedly connected to the wall 30 via the fixed nodes 10. Multiple wall panels 20 are arranged side-by-side to cover the wall 30. The external fixed node 10 includes a connecting structure 100 and a connecting plate 200. The connecting structure 100 is used for fixed connection to the wall panels 20, and the connecting plate 200 is used for fixed connection to the wall 30. The wall 30 has a corner where it has two outer surfaces extending in different directions. Two wall panels need to be fixedly connected to these two outer wall surfaces respectively. Specifically, as shown... Figure 1As shown, the corner of the wall 30 has a first surface 31 and a second surface 32. The extending directions of the first surface 31 and the second surface 32 form a target angle. For example, the target angle can be 90 degrees. At the same time, at least two wall panels 20 are fixed to the first surface 31 and the second surface 32 respectively. That is, at least one wall panel 20 is fixed to each of the first surface 31 and the second surface 32, and there is an angle between the thickness directions of the two wall panels 20. In order to reliably fix the wall panels 20 to the wall 30, the angle needs to be as similar as possible to the target angle. The external wall structure also includes an extension frame 40 to fix the two wall panels to the two surfaces respectively at the corner. The structure of the extension frame 40 is described below with reference to various embodiments.

[0054] like Figure 1 As shown, the extension frame 40 is fixed to the end of the wall panel 20 and to the side of the wall panel closest to the wall. This end is the end of the wall panel 20 near the corner, thus forming a support frame for the wall panel 20 on the inner side of the wall panel 20 at the corner. This corner can be a horizontal corner or a corner between the horizontal and vertical directions, improving the structural rigidity of the wall panel 20 at the corner and reducing the risk of damage to the wall panel 20 at the corner. Simultaneously, the extension frame 40 needs to ensure that the included angle in the thickness direction of adjacent wall panels 20 at the corner is the same as the target included angle formed by the two surfaces of the wall 30. Therefore, further structural adjustments to the extension frame 40 are required, such as... Figure 2 As shown, two extended frames 40 are fixedly connected to two wall panels 20 at the corner. Each extended frame 40 includes a mating surface 41 and a splicing surface 42. The mating surface 41 is mated to the wall panel 20. The included angle between the mating surfaces 41 of the two extended frames 40 is the same as the target included angle between the two surfaces of the wall 30 at the corner. By mating the two wall panels to the mating surfaces 41 of the two extended frames 40, the included angle in the thickness direction of the two wall panels 20 can be made as similar as possible to the target included angle, thereby improving the flatness of the exterior wall structure at the corner. At the same time, the extension direction of the splicing surface 42 of the two extended frames 40 forms a preset angle with the extension direction of the mating surface 41. The sum of the preset included angles of the two extended frames 40 is the same as the target included angle. This can be understood as making the included angle between the mating surfaces 41 of the two extended frames 40 the same as the target angle, while making the splicing surfaces 42 of the two extended frames 40 relatively set, thereby reducing the risk of assembly interference between the two extended frames 40.

[0055] Optionally, the two splicing surfaces 42 can abut against each other to support the two extended frames 40, thereby further improving the structural rigidity of the wall panel 20 at the corner; alternatively, the two splicing surfaces 42 can also be spaced apart from each other, thereby providing adjustment space for the connection position of the two extended frames 40, thereby further reducing the risk of assembly interference between the two extended frames 40.

[0056] This utility model embodiment provides an exterior wall structure with a corner. The exterior wall structure includes a wall with a corner, and at the corner, the wall has a first surface and a second surface, forming a target angle between the first and second surfaces. At least two wall panels are respectively fixed to the first and second surfaces. The exterior wall structure also includes extension frames, which are located horizontally at the ends of the wall panels and fixed to the side of the wall panel closest to the wall. Two extension frames are respectively fixedly connected to the two wall panels fixed to the first and second surfaces. Each extension frame includes a mating surface and a splicing surface. The mating surfaces of the extension frames are fixedly connected to two wall panels respectively. The splicing surfaces of the two extension frames are mated, and a preset angle is formed between the splicing surfaces and the mating surfaces. The sum of the two preset angles is the same as the target angle. This ensures that while the mating surfaces of the two extension frames are mated together, the angle between the mating surfaces of the two extension frames is the same as the target angle. After the two wall panels are mated to the two mating surfaces, the angle between the two wall panels is the same as the angle of the wall at the corner, improving the flatness of the exterior wall structure at the corner. Furthermore, because the splicing surfaces of the two extension frames can be set opposite each other, the height of the two extension frames is reduced.

[0057] The forces between the two extended frames can be transferred to each other, so that the extended frames can not only resist the positive force in the thickness direction of the wall panel, but also resist the torque borne by the wall panel through the abutment force between the two splicing surfaces, thereby improving the structural strength of the wall panel at the corner and reducing the risk of damage to the wall panel at the corner.

[0058] In some embodiments, such as Figure 2 As shown, the splicing surfaces 42 of the two extended frames 40 abut against each other, thereby enabling the two extended frames 40 to support each other and further improve the structural rigidity of the wall panel 20 at the corner. At the same time, the splicing surfaces 42 are concave to form splicing grooves 421. When the splicing surfaces 42 of the two extended frames 40 are in contact, the two splicing grooves 421 are connected, thereby splicing the two splicing grooves 421 to form an integral connecting groove. In addition, the exterior wall structure also includes a pin 70, which is located in the two connected splicing grooves 421 to fix the two adjacent extended frames together. It can be understood that by inserting the pin 70 into the integral connecting groove, the force between the pin 70 and the two splicing grooves 421 restricts the mutual misalignment of the two extended frames in the extension direction parallel to the splicing surfaces 42, thereby improving the connection reliability between the two extended frames 40 and thus enabling the two extended frames 40 to provide more reliable support for the wall panel 20.

[0059] In some embodiments, such as Figure 2As shown, the splicing groove 421 includes a connecting groove 422 and an enlarged groove 423. The connecting groove 421 is formed by the indentation of the splicing surface 42, thus forming an opening of the splicing groove 421 on the splicing surface 42. The two splicing grooves 421 are connected through the connecting groove 422. Meanwhile, the enlarged groove 423 is located on the side of the connecting groove 421 away from the splicing surface 42, and in the extending direction of the splicing surface 42, the size of the enlarged groove 423 is larger than the size of the connecting groove 421. At the same time, the pin 70 includes a connecting portion 71 and an enlarged portion 72. The two enlarged portions 72 are located at both ends of the connecting portion 71, and in the extending direction perpendicular to the connecting portion 71, the size of the enlarged portion 72 is larger than the size of the connecting portion 71. The connecting portion 71 is located in the two connecting slots 422 of the two adjacent splicing slots 421, and the two bulging portions 72 are respectively located in the two bulging slots 423 of the two extended frames 40. In the extension direction of the splicing surface 42, the size of the bulging portion 72 is larger than the size of the connecting portion 71, so that the bulging portion 72 can move into the connecting slot 421 in the extension direction parallel to the connecting portion 71. The force between the bulging portion 72 and the inner wall of the bulging slot 423 can limit the tendency of the two extended frames 40 to move away from each other, so that the connection between the two extended frames 40 is more reliable, and so that the two extended frames 40 provide more reliable support for the wall panel 20.

[0060] In some embodiments, such as Figure 3As shown, in the thickness direction of the extended frame, the size of the splicing groove 421 is larger than the size of the pin 70, that is, the length of the pin 70 is shorter than the length of the splicing groove 421. This allows installation space to be formed at both ends of the splicing groove 421 when the pin 70 is inserted. Simultaneously, the connecting groove 422 includes an arc-shaped groove 424. The arc-shaped grooves 424 of two adjacent splicing grooves 421 are joined to form an installation hole. This can be understood as the two arc-shaped grooves 424 each forming a semi-cylindrical structure, and the two arc-shaped grooves 424 are interconnected and joined to form a cylindrical installation hole. The external wall structure also includes connecting screws 60, which are located within the installation hole. In the thickness direction of the extended frame 40, two connecting bolts 60 are located on both sides of the splicing groove 421. This can be understood as... The connecting screw 60 is threaded in the mounting hole, thus forming a threaded hole that matches the external thread of the connecting screw 60. The connecting screw 60 is fixed to the end of the splicing groove 421. Since the installation space is formed at both ends of the splicing groove 421, the connecting screw 60 will not interfere with the pin 70 during assembly, nor will it affect the structural strength of the pin 70. Moreover, by fixing the connecting screw 60 to both sides of the splicing groove 421, the risk of the pin 70 coming out of the splicing groove 421 along the thickness direction of the extension frame 40 can be reduced. The connecting screw 60 can also limit the mutual misalignment of the two adjacent extension frames 40 in the direction parallel to the thickness of the extension frame 40, thereby making the connection between the two extension frames 40 more reliable and providing more reliable support for the wall panel 20.

[0061] In some embodiments, such as Figure 2 As shown, there are multiple splicing slots 421, each of which is located on the splicing surface 42. This allows for the provision of more splicing slots 421 while making full use of the dimensions of the splicing surface 42, thereby enabling a more reliable connection between two adjacent extension frames 40.

[0062] In some embodiments, such as Figure 3 As shown, the extension frame 40 also includes a protruding portion 43, which extends from the end of the extension frame 40 near the wall 30. At least one splicing groove 421 is located in the protruding portion 43. It can be understood that by setting the protruding portion 43 that extends beyond the body of the extension frame 40 to accommodate the splicing groove 43, the splicing of the extension frame 40 can be made sufficiently reliable while the splicing surface 42 does not need to be set to a large size, thereby reducing the overall size of the extension frame 40.

[0063] In some embodiments, such as Figure 1 As shown, the exterior wall structure also includes exterior wall fixing nodes 10, which are used to fix the wall panel 20 to the wall 30, wherein, for example... Figure 6As shown, 10 includes a connecting structure 100 and a fixing plate 200. The connecting structure 100 is fixedly connected to the wall panel 20. Specifically, the wall panel 20 adjacent to the longitudinal edge is fixedly connected to the wall panel 20 on both sides of the longitudinal direction. Figure 2 The extension frame 40 and the connecting structure 100 are fixedly connected. The fixing plate 200 is fixedly connected to the connecting structure 100 and to the wall 30, thereby making the wall panel 20 more reliably fixed to the wall 30.

[0064] In some embodiments, such as Figure 4 As shown, multiple connecting structures 100 and extension frames 40 are spliced ​​together to form a connecting frame 50. The connecting frame 50 surrounds and forms a closed shape. The connecting frame 50 is simultaneously connected with... Figure 1 Multiple connecting plates 200 are fixedly connected, so that the load of the wall panel 20 can be transferred to the connecting assembly 60 and multiple fixing plates 200 at the same time, so that the wall panel 20 can be more reliably fixed to the wall 30.

[0065] In some embodiments, such as Figure 5 As shown, adjacent connecting structures 100 or connecting structures 100 and extension frames 40 in connecting frame 50 are fixedly connected by corner brackets 51. Corner brackets 51 are sheet-like structures, each consisting of two parts whose extending directions form an angle, such as a right angle. By fixing the two parts of 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 5 The 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.

[0066] In some embodiments, such as Figure 6 As shown, the extension frame 40 also includes a protruding portion 44, which extends from the end of the extension frame 40 near the wall 30. The protruding portion 44 and the connecting structure 100 surround and form a protective cavity 52, and the corner bracket 51 is located inside the protective cavity 52. ​​At the same time, the outer wall structure also includes a mortar layer 80, which covers the corner bracket 51, thereby protecting the corner bracket 51 inside the protective cavity 52 and improving the connection reliability of the corner bracket 51.

[0067] In some embodiments, such as Figure 7 As shown, the exterior wall structure also includes a transition structure 300, which is fixedly connected to the side of the extension frame 40 near the connecting structure 100, wherein, as... Figure 8As shown, multiple connecting structures 100 and at least one transition structure 300 are spliced ​​together to form a connecting frame 50. The connecting frame 50 is also fixedly connected to multiple fixed plates 200. It can be understood that by setting the transition structure 300, the extension frame 40 can form a connecting frame 50 with the connecting structure 100 through the transition structure 300. Thus, the load borne by the extension frame 40 can also be transferred to multiple fixed plates 200 through the connecting frame 50 at the same time, thereby improving the load-bearing capacity of the extension frame 40 and facilitating the splicing of the transition structure 300 and the connecting structure 100 to form the connecting frame 50. Optionally, when the extension frame 40 is spliced ​​with the connecting structure to form the connecting frame 50 through the adapter structure 300, since most of the force on the extension frame 40 is transferred to the fixed plate 200 by the adapter structure 300 and the extension frame, it is not necessary for the splicing surface of the adjacent extension frame 40 to bear the load at the corner. Thus, the splicing surface 43 of the adjacent extension frame 40 can be set as a plane, or the splicing surface 43 of the adjacent extension frame 40 can be set at intervals, thereby improving the assembly convenience of the extension frame 40.

[0068] In some embodiments, such as Figure 9 As shown, the second surface 12 is a vertical plane, that is, the corner of the exterior wall structure is the corner between the vertical and horizontal directions. The wall panel 20 includes a vertical wall panel 22, which is fixedly connected to the second surface 12. The extension frame 40 includes a vertical frame 45. The transition structure 300 includes a vertical transition structure 320, which is fixedly connected to the vertical frame 45 and also fixedly connected to the second surface 12. Figure 8 The connecting frame 50 in the middle transfers the load of the vertical wall panel 22 to the fixed part. Figure 1 In the case of the fixing plate 200 on the second surface 12, the fixing plate 200 is subjected to tangential force and bending moment. Compared with the fixing plate 200 which bears positive force, the fixing plate 200 has a weaker ability to bear tangential force and bending moment. By fixing the vertical transition structure 320 to the second surface 12, the fixing plate 200 is assisted in bearing the tangential force and bending moment, thereby enabling the vertical frame 45 and the second wall panel 22 to be more reliably fixed to the second surface 12. Optionally, the vertical transition structure 320 can be directly fixed to the second surface 12, or the vertical transition structure 320 can be indirectly fixed to the second surface 12 through a connecting structure.

[0069] In some embodiments, such as Figure 9As shown, the exterior wall structure also includes a splicing connection plate 400 and a splicing fixing plate 500. The splicing connection plate 400 is fixedly connected to the vertical transition structure 320, and the splicing fixing plate 500 is fixed to the second surface 12. The splicing connection plate 400 and the splicing fixing plate 500 are fixedly connected. By setting the splicing connection plate 400 and the splicing fixing plate 500, it is possible to easily fix the vertical transition structure 320 to the second surface 12 even when there is a certain distance between the vertical transition structure 320 and the second surface 12.

[0070] In some embodiments, such as Figure 10 As shown, the vertical transition structure 320 has a first limiting groove 321 on its outer surface in the vertical direction. The first limiting groove 321 includes a vertical portion 3211 and a horizontal portion 3212. The vertical portion is formed by the indentation of the top of the vertical transition structure 320. The horizontal portion 3212 and the vertical portion 3211 are connected, thereby forming an L-shaped groove structure with an opening located in the vertical portion 3211. Meanwhile, the splicing connecting plate 400 includes a connecting plate body 410 and a first limiting protrusion 420. The first limiting protrusion 420 is located in the vertical direction. Within the vertical portion 3211 and the horizontal portion 3212, it can be understood that the first limiting protrusion 420 extends into the horizontal portion 3212 through the vertical portion 3211, thereby forming a hook-and-loop engagement between the first limiting protrusion 420 and the vertical portion 3211 and the horizontal portion 3212. The force between the horizontal portion 3212 and the first limiting protrusion 420 bears the vertical force of the wall panel 20, and the force between the vertical portion 3211 and the first limiting protrusion 420 bears the horizontal force of the vertical wall panel 22. Simultaneously, through… The horizontal portion 3212 and the vertical portion 3211, together with the first limiting protrusion 420, bear the torque of the vertical transition structure 320, thereby fixing the vertical transition structure 320 to the splicing connecting plate 400. It should be noted that when connecting the relevant boundary frame and boundary connecting plate, the boundary connecting frame and boundary connecting plate need to be directly fixed together with screws or rivets. Therefore, the boundary frame and boundary connecting plate need to be positioned during installation. This is especially difficult when the boundary connecting plate and the connecting plate are spliced ​​together to form a connecting frame. The horizontal portion 3212 and the vertical portion 3211 form a hook structure with the first limiting protrusion 420. When the vertical adapter structure 320 is fixedly connected to the splicing connecting plate 400, the vertical adapter structure 320 can be pushed laterally to form a hook connection between the vertical adapter structure 320 and the splicing connecting plate 400. This forms a preliminary positioning connection before the vertical adapter structure 320 and the splicing connecting plate 400 are further fixed, thus eliminating the need to position the vertical adapter structure 320 during installation and making the installation of the vertical adapter structure 320 more convenient.

[0071] In some embodiments, such as Figure 10As shown in the structure, the vertical transition structure 320 includes a connecting structure body 322 and a limiting portion 323. The limiting portion 323 extends from the end of the connecting structure body 322 near the second surface 12. The limiting portion 323 includes a protruding protrusion 3231 and an abutting protrusion 3232. The protruding protrusion 3231 extends from the end of the limiting portion 323, and the abutting protrusion 3232 extends from the outer surface of the protruding protrusion 3231 and extends vertically, thereby allowing the connecting structure body 322 to... A second limiting groove 3233 is formed between the end of 22, the protruding protrusion 3231 and the abutting protrusion 3232; at the same time, the splicing connecting plate 400 also includes a second limiting protrusion 430, which is located in the second limiting groove 3233 and abuts against the abutting protrusion 3232. The force between the second limiting protrusion 430 and the abutting protrusion 3232 limits the horizontal force carried by the vertical transition structure 320 and the torque applied by the longitudinal transition structure 320.

[0072] In some embodiments, such as Figure 10 As shown, the splicing connecting plate 400 abuts against the end of the vertical transition structure 320 near the second surface 12, thereby enabling the splicing connecting plate 400 to further restrict the lateral displacement of the boundary vertical transition structure 320.

[0073] In some embodiments, such as Figure 11 As shown, the end of the vertical transition structure 320 near the second surface 12 is recessed to form a guide groove 324. The splicing connecting plate 400 also has a guide protrusion 440, which is located in the guide groove 324. It can be understood that during the process of the vertical transition structure 320 and the splicing connecting plate 400 being initially positioned by lateral pushing, the vertical connecting structure 320 is guided by the force between the guide protrusion 440 and the guide groove 324, thereby further improving the assembly convenience of the boundary connecting structure 100 and the boundary connecting plate 200. The external wall structure also includes connecting screws 700, which pass through guide protrusions 440 and fix the splicing connecting plate 400 and vertical transition structure 320. Thus, the splicing connecting plate 400 and vertical transition structure 320 are fixedly connected. It can be understood that the connecting screws 700 are set at the position where the splicing connecting plate 400 has a large thickness, that is, at the position where the guide protrusions 440 are, thereby improving the connection reliability between the connecting plate 400 and vertical transition structure 320.

[0074] In some embodiments, such as Figure 11 As shown, the inner wall of the guide groove 324 is recessed to form a corner bracket guide groove 3241. The outer wall structure also includes a corner bracket 51, which is located inside the guide groove 3241. The corner bracket 51 is used to connect the vertical transition structure 320 and the connecting structure 100 to form a... Figure 8The connecting frame 50 in the middle is equipped with a guide groove 3241 to facilitate the installation of the corner bracket 51. At the same time, the guide protrusion 440 abuts against the corner bracket 51, so that the corner bracket 51 can be more reliably located in the guide groove 3241, thereby improving the structural strength of the connecting frame 50.

[0075] In some embodiments, such as Figure 12 As shown, the end of the splicing connecting plate 400 is bent to form a first hook 450, and the splicing fixing plate 500 has a second hook 510. The first hook 450 is hooked onto the second hook 510. It can be understood that the first hook 450 is located on top of the second hook 510 and the end of the first hook 450 extends into the space surrounded by the second hook 510, thereby fixing the splicing connecting plate 400 and the splicing fixing plate 500 together by hooking.

[0076] The second hook 510 surrounds and forms a hooking space 511. The horizontal dimension of the hooking space 511 is larger than that of the first hook 450, thus creating a clearance fit between the first hook 450 and the second hook 510, reducing the difficulty of hooking the first hook 450 and the second hook 510. The exterior wall structure also includes a gasket 600, located within the hooking space 511 and having a slot 610. The first hook 450 extends into the hooking space 511, with its end extending into the slot 610. The horizontal dimension of the slot 610 is approximately the same as the dimension of the hooking space 511, creating a transition fit between the slot 610 and the hooking space 511. Furthermore, the horizontal dimension of the slot 610 is approximately the same as the horizontal dimension of the end of the first hook 450, creating a transition fit between the slot 610 and the end of the first hook 450. These two transition fits determine the horizontal position of the first hook 450. Simultaneously, as... Figure 13 As shown, the gasket 600 includes various models. Each model of gasket 600 has the same size in the horizontal direction and forms a horizontal edge 420 at the edge position. The spacing between the slot 610 in each model of gasket 600 and the horizontal edge 420 is different. It can be understood that by selecting different models of gaskets, the position of the slot 610 in the horizontal direction can be adjusted, thereby adjusting the horizontal position of the first hook 450, and thus realizing the fine adjustment of the horizontal position of the splicing connecting plate 400 and the wall panel 20 fixedly connected to the splicing connecting plate 400.

[0077] Optional, such as Figure 13 As shown, the spacing between the slots 610 and the horizontal edges 620 in each type of gasket 600 forms an arithmetic sequence, for example, as... Figure 13 Three types of gaskets 600 are provided, with the slots 610 and the horizontal edge 620 of the three types of gaskets 600 having spacings of D1, D2 and D3 respectively, and these three spacings being 5 mm, 5.5 mm and 6 mm respectively.

[0078] Optional, such as Figure 14 As shown, the vertical transition structure 320 is a one-piece structure made of metal. It can be understood that the vertical transition structure 320 needs to be supported by the tangential force and torque of the auxiliary fixing plate 200, thus requiring the vertical transition structure 320 to be set as a one-piece structure with higher structural strength.

[0079] In some embodiments, such as Figure 15 As shown, the first surface 11 is a horizontal plane. The wall panel 20 includes a horizontal wall panel 21, which is fixed to the first surface 11. The extension frame 40 includes a horizontal frame 46, which is fixedly connected to the horizontal wall panel 21. The transition structure 300 includes a horizontal transition structure 310, which is fixedly connected to the horizontal wall panel 21. The horizontal transition structure 310 includes a first part 311 and a second part 312, which are connected. The first part 311 is fixedly connected to the horizontal wall panel 21, and the second part 312 is connected to the horizontal frame 46. It should be noted that the horizontal transition structure 310 does not need to be connected to the first surface 11, thus allowing the load borne by the horizontal frame 46 to be distributed through... Figure 8 The connecting frame 50 in the middle is transferred to the fixed plate 200, so that the load-bearing requirement of the horizontal transition structure 310 is very small, and the horizontal transition structure 310 can be set as a split structure with low structural strength.

[0080] Optionally, the first part 311 is made of metal and the second part 312 is made of polymer. It can be understood that the first part 311 needs to bear the load of the horizontal wall panel 11, so it needs to be made of metal. The second part 312 has a small load requirement, so the material can be set as a polymer with lower strength but lighter weight, thus achieving the lightweight of the exterior wall structure.

[0081] In some embodiments, such as Figure 16 As shown, the end of the adapter structure 300 near the wall 10 has a corner bracket guide groove 330. The end of the adapter structure 300 near the wall 10 is connected to the connecting structure 100 via a corner bracket 51. The corner bracket 51 is located within the corner bracket guide groove 330, thus facilitating the installation of the corner bracket 51; wherein, as... Figure 17 As shown, at the end perpendicular to the corner bracket 51, the corner bracket 51 has a guide slope 511, which helps the corner bracket 51 to align with the corner bracket guide groove 330 during the process of pushing the corner bracket 51 into the corner bracket guide groove 330, thereby facilitating the installation of the corner bracket 51.

[0082] In some embodiments, such as Figure 18As shown, the end of the adapter structure 300 facing the wall panel 20 has a fitting cavity 340. The fitting cavity 340 is used to accommodate structural adhesive, which is used to fix the adapter structure 300 to the wall panel 20. By accommodating more structural adhesive in the fitting cavity 340 and confining the structural adhesive within the space of the fitting cavity 340, the fixing reliability between the adapter structure 300 and the wall panel 20 is further improved.

[0083] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. 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.
