[0175] 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.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] In the following specific embodiments, the wall panels in the exterior wall structure can be made of any material. For example, the wall panels can be one or more combinations of metal panels, tempered glass panels, ceramic tiles, stone slabs, and concrete slabs. The wall panels can be fixed to the wall in a dry-hanging, wet-hanging, or partially dry-hanging and partially wet-hanging manner. Depending on the specific structure of the exterior wall structure, it can be used to achieve various functions. For example, a heat-insulating filling layer can be used in the exterior wall structure to achieve heat insulation or thermal insulation; a vacuum insulation layer can be used in the exterior wall structure to achieve sound insulation; and wall decorations can be added to the exterior wall structure to improve the aesthetics of the building. The above structures can also be used in combination to enable the exterior wall structure to achieve multiple functions simultaneously. The following examples illustrate different components in the exterior wall structure and the overall structure of the exterior wall structure.

[0180] First, combine Figure 1 Describe the usage environment of the exterior wall structure, such as Figure 1As 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.

[0181] In some embodiments, such as Figure 2 As shown, the connection structure 100 is applied to, for example Figure 1 The external wall fixing node 10 shown includes a connecting structure 100 comprising a fitting wall 110, an extension wall 120, and a branch wall 130. The outer surface of one side of the fitting wall 110 forms a fitting surface 111, which is used to fit against the wall panel 20 to achieve a fixed connection. It should be noted that the fitting surface 111 can be directly fixed to the wall panel 20 using structural adhesive. Alternatively, the fitting surface 111 can form a groove to accommodate structural adhesive and fit against the wall panel 20, thereby achieving a fixed connection.

[0182] The extension wall 120 extends from the surface of the mating wall 110 opposite to the mating surface 111, that is, from the surface of the mating wall 110 towards the mating surface 111. Figure 1 The wall 30 extends outwards, and at the same time, the extension wall 120 extends along the first direction (the first direction is as follows). Figure 2 (As indicated by the solid arrow in the middle) The first direction is not parallel to the mating surface 111, so that the extension wall 120 can extend away from the mating wall 110. Optionally, the extension wall 120 forms an acute angle with the mating surface 111. When assembling the wall panel 20, the extension wall 120 is tilted upward, that is, the end of the extension wall 120 that is fixed to the mating wall 110 is higher than the other end that extends. After the wall panel 20 is assembled, the tilted extension wall 120 is pressed down by the gravity of the wall panel 20, thereby applying prestress to the wall panel 20, improving the load-bearing capacity of the extension wall 120, and thus improving the reliability of the wall panel 20 fixing. Optionally, the first direction is perpendicular to the mating surface 111, so as to make full use of the size of the extension wall 120 to facilitate fixing with the wall 30. Moreover, setting the first direction to be perpendicular to the mating surface 111 can also facilitate the positioning when installing the wall panel 20. The following structural description will be based on the first direction being perpendicular to the mating surface 111.

[0183] Branch wall 130 extends from the outer surface of extension wall 120, wherein branch wall 130 and extension wall 120 surround to form first cavity 141. In a first direction, mating surface 111 and first cavity 141 are located on both sides of mating wall 110, and the first opening of first cavity 141 faces a second direction (the second direction is as follows). Figure 2 (As shown by the dashed arrow in the middle), the second direction is perpendicular to the first direction during the assembly of wall panel 20. Figure 1 The connecting plate 200 can extend into the first cavity 141 and be fixedly connected to the connecting structure 100. This can be understood as follows: when the connecting structure 100 is fixedly connected to the wall panel 20 and the connecting plate 200, the first opening of the first cavity 141 faces vertically. The gravity exerted by the wall panel 20 on the connecting structure 100 can be transmitted to the connecting plate 200 through the force between the side wall of the first cavity 141 and the connecting plate 200, converting part of the bending moment borne by the connecting plate 200 into tensile stress. Specifically, the gravity of the wall panel 20 is transmitted to the connecting plate 200 through the connecting structure 100. At this time, the connecting plate 200 mainly bears the bending moment caused by this gravity. Under the action of this bending moment, one side of the connecting plate 200 is under tension, and the other side... Under compression, the tensile capacity of a tough material is greater than its compressive capacity. By setting the first cavity 141, the bending moment transmitted from the connecting structure 100 to the connecting plate 200 can be converted into tensile stress. At this time, the stress on the compressive side of the connecting plate 200 can be offset by this tensile stress, and the stress on the tensile side of the connecting plate 200 is superimposed with this tensile stress. That is, the tensile effect of the connecting plate 200 is enhanced and the tensile effect is weakened. Since the connecting plate 200 is generally made of a tough material, such as metal, the stress state of the connecting plate 200 is optimized by this tensile stress, thereby making better use of the tensile capacity of the connecting 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.

[0184] This utility model provides a connection structure for use in exterior wall fixing nodes. This structure is used to attach to a wall panel and be fixedly connected to a connecting plate. The connection structure includes an attachment wall with an attachment surface, an extension wall extending from the attachment wall, and a branch wall extending from the outer surface of the extension wall. The extension wall and the branch wall surround and form a first cavity. In the assembled state with the wall panel, a portion of the connecting plate extends into the first cavity. The force between the side wall of the first cavity and the connecting plate can convert part of the bending moment exerted by the wall panel on the connecting plate into tensile stress. This tensile stress can offset the compressive stress on the compression side of the connecting plate and enhance the tensile stress on the tension side of the connecting plate. Since the connecting plate is generally made of a tough material with a tensile strength greater than its compressive strength, by setting the first cavity, the stress condition of the connecting plate can be optimized to better suit the material performance advantages of the connecting plate, thereby improving the load-bearing capacity of the connecting plate and thus improving the reliability of the exterior wall fixing node.

[0185] In some embodiments, such as Figure 3 As shown, the mating wall 110, the extension wall 120, and the branch wall 130 are all along a third direction (the third direction is as follows). Figure 3 Extending from the midpoint (as indicated by the dashed arrow), the third direction is perpendicular to the first direction (as shown by the first direction). Figure 3 (as shown by the solid arrow) perpendicular to and in line with the second direction (as shown by the solid arrow) Figure 3 As shown by the dashed arrow, this can be understood as follows: within a cross-section perpendicular to the third direction, the fitting wall 110, the extending wall 120, and the branch wall 130 form a cross-sectional shape with a first cavity 141. Simultaneously, the fitting wall 110, the extending wall 120, and the branch wall 130 extend along the third direction to form a plate-like or strip-like structure, thus forming a structure capable of interacting with... Figure 1 While the connecting plate 200 in the middle more reliably connects to the first cavity 141, it also increases the fixing area with the connecting plate 200 and the wall plate 20 in the third direction, further improving the connection reliability between the connecting structure 100 and the wall plate 20 and the connecting plate 200.

[0186] In some embodiments, such as Figure 4 As shown, in third-party direction (third-party direction such as...) Figure 4 As shown by the middle arrow, the first cavity 141 extends from one end of the extension wall 120 to the other end of the extension wall 120. It can be understood that the connecting structure 100 has a first cavity 141 in each section perpendicular to the third direction. The connecting structure 100 can be formed by integral molding. Optionally, the part of the connecting structure 100 that forms the first cavity 141 is made of metal profile. The through first cavity 141 can facilitate the metal profile to form a structure with the first cavity 141 by integral molding.

[0187] In some embodiments, such as Figure 5 As shown, in third-party direction (third-party direction such as...) Figure 5 As indicated by the middle arrow, the size of the first cavity 141 is smaller than the size of the extension wall 120. This can be understood as follows: in each section of the connecting structure 100 perpendicular to the third direction, some sections have the first cavity 141, while others do not. This is necessary when... Figure 1The connecting plate 200 has a first cavity 141 in the mating portion, while the connecting structure 100 in other portions is configured without the first cavity 141. This improves the assembly reliability of the connecting structure 100 and the connecting plate 200 while also increasing the overall structural strength of the connecting structure 100. The first cavities 141 can be continuously distributed in the third direction, or multiple first cavities 141 can be spaced apart in the third direction. It should be noted that the non-through first cavity 141 can also be formed on a one-piece molding basis. For example, a solid structure with a target shape but without an internal first cavity can be formed by one-piece molding, and then the first cavity 141 can be formed by machining, such as milling.

[0188] In some embodiments, such as Figure 6 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 7 to 12 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 7 to 12 Other methods are shown.

[0189] like Figure 7 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 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.

[0190] Optional, such as Figure 7 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 7 (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.

[0191] Optional, such as Figure 8 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 Figures 8 to 11 The structure of positioning structure 191 is illustrated by way of example.

[0192] like Figure 8 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 8As 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 connecting structures 100 to be spliced ​​to form a cavity for accommodating the corner bracket 51.

[0193] like Figure 9 As shown, the positioning structure 191 includes a positioning protrusion 193, the positioning protrusion 193 being along a first direction (the first direction is as follows). Figure 9 (As indicated by the middle arrow) protruding from the positioning end, the positioning protrusion 193 abuts against the corner code 51 in a direction perpendicular to the first direction. This can be understood as the corner code 51 abutting against the positioning end to restrict the movement of the corner code 51 relative to the connecting structure 100 in the first direction, and the positioning protrusion 193 restricts the movement of the corner code 51 relative to the connecting structure 100 in a direction perpendicular to the first direction, thereby enabling the corner code 51 to be positioned at the target position. It should be noted that the corner code 51 can approach the positioning protrusion 193 from different directions. For example, the corner code 51 approaches the positioning protrusion 193 along the first direction and abuts against the positioning protrusion 193 in a direction perpendicular to the first direction. For example, the corner code 51 approaches the positioning protrusion 193 along the direction perpendicular to the first direction after approaching the positioning end and abuts against the positioning protrusion 193.

[0194] Optional, such as Figure 10As shown, the corner bracket 51 includes a first connecting portion 511 and a second connecting portion 512. A first angle is formed between the extending directions of the first connecting portion 511 and the second connecting portion 512, such as 90 degrees. The first portion 511 and the second portion 512 are respectively connected to two adjacent connecting structures 100 in the connecting frame 50, thereby enabling the connecting structures 100 to be spliced ​​to form the connecting frame 50. Simultaneously, the positioning protrusions 193 of adjacent connecting structures 100 in the connecting frame 50 abut against the first connecting portion 511 and the second connecting portion 512, and the two positioning protrusions 193... The first included angle is formed between the extension directions. This can be understood as the two adjacent connecting protrusions 193 of the connecting structure 100 splicing together to form a protrusion structure with the same shape as the corner code 51 perpendicular to the thickness direction. The two connecting protrusions 193 can abut against the two connecting parts of the corner code 51 in two orthogonal directions perpendicular to the first direction (e.g., the second direction and the third direction), thereby restricting the movement of the corner code 51 relative to the connecting structure 100 in the above two orthogonal directions. 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.

[0195] Optional, such as Figure 11 As shown, the connecting structure 100 has a plurality of positioning protrusions 193, each positioning protrusion 193 being along a second direction (the second direction is as shown in the figure). Figure 11 (As shown by the dashed arrow) The positioning protrusions 193 are spaced apart, and adjacent positioning protrusions 193 surround each other to form a positioning space. The inner wall of the positioning space is used to abut against the corner bracket 51. It can be understood that the positioning space has a direction facing the first direction (the first direction is as shown by the dashed arrow). Figure 11 The corner bracket 51 is inserted into the positioning space through the opening (as indicated by the solid arrow in the middle) along the first direction and abuts against the positioning protrusion 193 that surrounds and forms the positioning space. The corner bracket 51 is clamped by the two adjacent positioning protrusions 193, thereby more reliably positioning the corner bracket 51 to the target position. At the same time, the two adjacent positioning spaces in the connecting frame 50 are used to accommodate the first connecting part 511 and the second connecting part 512 of the corner bracket 51, respectively. It can be understood that the two adjacent positioning protrusions 193 in the connecting frame 50 form two positioning spaces. The two positioning spaces are connected and spliced ​​to form a space with the same shape as the corner bracket 51 perpendicular to the thickness direction. The first connecting part 511 and the second connecting part 512 can be positioned by the two positioning spaces, thereby simplifying the structure of the positioning protrusion 193 of the single connecting structure 100.

[0196] Optional, such as Figure 11 As shown, in the first direction (the first direction is as follows) Figure 11 On the solid arrow (as shown in the middle), the positioning protrusion 193 has a first guide surface 194, in the second direction (the second direction is as shown in the middle arrow). Figure 11(As shown by the dashed arrow in the middle) The first guide surface 194 is located on the side close to the corner bracket 51. It can be understood that during the process of moving the corner bracket 51 closer to the positioning protrusion 193 along the first direction, the corner bracket 51 can abut against the first guide surface 194. In the direction of the positioning protrusion 193 extending from the positioning end, the cross-sectional area of ​​the positioning protrusion 193 decreases. This cross-section is a plane perpendicular to the extension direction of the positioning protrusion 193. During the process of moving the corner bracket 51 closer to the positioning protrusion 193 along the first direction, the first guide surface 194 can move the corner bracket 51 closer to the target position. During the automated assembly of the corner bracket 51 and the connecting structure 100, the moving structure can position the corner bracket 51 to the target position with the assistance of the first guide surface 194.

[0197] Optionally, the first connecting portion 511 and the second connecting portion 512 of the corner bracket 51 both have connecting holes. The number of connecting holes in the first portion 511 and the second connecting portion 512 is at least one. Multiple connecting holes can facilitate the leveling of the corner bracket 51, while a single connecting hole can enable the corner bracket 51 to be assembled with the connecting structure 100 more quickly.

[0198] like Figure 12As 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 using connecting pins. Specifically, a clearance fit or 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 using a pin. 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 of the connecting structure 100 form an interference fit by simultaneously squeezing the corner assembly 52 into the slots of two adjacent connecting structures 100, without the need for pin holes in the connecting structure 100. The following examples illustrate the insertion methods of the corner assembly 52 and the connecting structure 100.

[0199] In some embodiments, such as Figure 13 As shown, the extension wall 120 also surrounds and forms a first insertion cavity 181 and a second insertion cavity 182, the first insertion cavity 181 and the second insertion cavity 182 along a first direction (the first direction is as follows). Figure 13 (As indicated by the middle arrow) The first insertion cavity 181 and the second insertion cavity 182 are spaced apart and both are used to accommodate Figure 13 A portion of the corner 52, namely, inserting the two corners into the first insertion cavity 181 and the second insertion cavity 182 of the two connecting structures 100 respectively, so that both ends of the two connecting structures 100 in the first direction are connected by the corner 52; wherein, as Figure 14 As shown, the first insertion cavity 181 has a second opening, and the second insertion cavity 182 has a third opening, in a third direction (the third direction is as follows). Figure 14As indicated by the middle arrow, the two second openings of the first insertion cavity 181 are located at both ends of the extension wall 120, and the two third openings of the second insertion cavity 182 are located at both ends of the extension wall 120. It can be understood that both the first insertion cavity 181 and the second insertion cavity 182 extend to the end of the extension wall 120 in the third direction, thereby facilitating the insertion of the assembly 40 into the first insertion cavity 181 and the second insertion cavity 182 from the third direction. It should be noted that the two insertion cavities can form two openings in the third direction in any way. Optionally, the two insertion cavities can penetrate the connecting structure 100 along the third direction to form openings at both ends of the extension wall 120. Optionally, the two insertion cavities can be spaced apart in the third direction and located at both ends of the extension wall 120 in the third direction, thereby forming two openings in the third direction.

[0200] Optional, such as Figure 15 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.

[0201] Optional, such as Figure 16 As shown, when the corner assemblies 52 are assembled with the two connecting structures 100, a portion of the corner assemblies 52 is contained within the two connecting structures 100, while the other portion of the corner assemblies 52 is located outside the connecting structures 100. For example, in the extending direction of the connecting structures 100, the edges of the two connecting structures 100 are perpendicular to each other. When the two connecting structures 100 are spliced ​​together by the corner assemblies 52, a certain space is formed between the two edges. A portion of the corner assemblies 52 is located in this space and is not contained within the connecting structures 100. Optionally, the connecting frame 50 also includes a corner assembly sleeve 53, which is fitted over the portion of the corner assemblies 52 that is not contained outside the connecting structures 100, thereby protecting the corner assemblies 52.

[0202] In some embodiments, such as Figure 17 As shown, in third-party direction (third-party direction such as...) Figure 17 As shown by the arrow, the first insertion cavity 181 and the second insertion cavity 182 both extend from one end of the extension wall 120 to the other end of the extension wall 120. That is, the first insertion cavity 181 and the second insertion cavity 182 are both additional insertion cavities, and both insertion cavities penetrate the connecting structure 100 in a third direction, thereby forming openings on both sides of the connecting structure 100.

[0203] In some embodiments, such as Figure 18 As shown, the first insertion cavity 181 has two, and in the third direction (the third direction is as follows) Figure 18 As indicated by the middle arrow, and in two directions, the two first insertion cavities 181 are located at both ends of the extension wall 120. This can be understood as the two first insertion cavities 181 being spaced apart in the third direction, and the length of the first insertion cavity 181 in the third direction being less than the length of the connecting structure 100, thereby enabling the connection to pass through... Figure 12 The corner bracket 52 connects the two connecting structures 100 and can also reduce the impact of the first insertion cavity 181 on the structural strength of the connecting structure 100. The two first insertion cavities 181 may or may not be connected to the first cavity 141, and the first insertion cavities 181 and the first cavity 141 can be arranged in any way. It should be noted that the first insertion cavity 181 may only have a second opening facing a third direction. After inserting the corner bracket 52 into the first insertion cavity 181, the connector is inserted into the connecting structure 100 and the corner bracket 52 from the second direction, thereby fixing the connecting structure 100 and the corner bracket 52 together. Alternatively, the first insertion cavity 181 may have openings in both the third and second directions. After inserting any opening of the corner bracket 52 into the first insertion cavity 181, the connector is inserted into the connecting structure 100 and the corner bracket 52 from one side of the extension wall 120 along the second direction, thereby fixing the connecting structure 100 and the corner bracket 52 together.

[0204] In some embodiments, such as Figure 18 As shown, the second insertion cavity 182 has two, and in the third direction (the third direction is as follows) Figure 18 As indicated by the middle arrow, and in two directions, the two second insertion cavities 182 are located at both ends of the extension wall 120. This can be understood as the two second insertion cavities 182 being spaced apart in the third direction, and the length of the second insertion cavity 182 in the third direction being less than the length of the connecting structure 100, thereby enabling the connection to pass through... Figure 12 The corner 52 in the middle connects the two connecting structures 100, and can also reduce the impact of the second insertion cavity 182 on the structural strength of the connecting structure 100.

[0205] In some embodiments, such as Figure 19 As shown, the connecting structure 100 also includes a support wall 183 in the second direction (the second direction is as shown in the figure). Figure 19 As shown by the solid arrow in the middle, the support wall 183 is fixed to the end of the branch wall 130, and in the third direction (as shown by the third direction)... Figure 19As shown by the dashed arrow, two support walls 183 are located at both ends of the branch wall 130. The extension wall 120, the branch wall 130, and the support wall 183 surround and form the first insertion cavity 181. It can be understood that by setting the support wall 183, the first insertion cavity 181 has only a second opening facing a third direction. After the corner piece 52 is inserted into the first insertion cavity 181 through the second opening, the support wall 183 can support the corner piece 52, so that the corner piece 52 does not need to be clamped or positioned. At this time, the connector is inserted into the support wall 183 and the corner piece 52 from one side of the support wall 183, thereby fixing the connection structure 100 and the corner piece 52 together. Optionally, the second insertion cavity 182 also has only a third opening facing a third direction, that is, the second insertion cavity 182 can also form a support structure in the second direction. During the process of assembling the connecting structure 100 and the corner assembly 52 into the connecting frame 50 by the automated splicing device, the connecting structure 100 can be stably placed on the assembly station of the automated splicing device by the support wall 183 and the support structure of the second insertion cavity 182. At this assembly station, the automated splicing device can automatically insert the corner assembly into the two connecting structures 100, and can also automatically insert the connecting screws into the connecting structure 100 and the corner assembly 52 along the second direction by the support wall 183 and the support structure, thereby automatically splicing multiple connecting structures 100 into the connecting frame 50. Among them, the first insertion cavity 181 and the first cavity 141 can be arranged in any form. For example, the first insertion cavity 181 and the first cavity 141 are arranged along the first direction, or the first insertion cavity 181 and the first cavity 141 are arranged along the second direction. Optionally, combined with Figure 19 and Figure 20 The first insertion cavity 181 and the first cavity 141 are arranged along the third direction. The two first insertion cavities 181 are located on both sides of the first cavity 141 and are connected to the first cavity 141. This structure can be formed by integral molding and machining. For example, an initial cavity is first formed by integral molding through the extension wall 120 along the third direction. The initial cavity has a support wall 183 and the support wall 183 extends from one end of the extension wall 120 to the other end in the third direction, so that the two openings of the first insertion cavity 181 are formed only in the third direction. Then, the opening of the first cavity 141 is formed on the support wall 183 by milling, thereby forming the first cavity 141.

[0206] In some embodiments, such as Figure 21As shown, the extension wall 120 also surrounds and forms a second cavity 142. It can be understood that the extension wall 120 surrounds and forms the second cavity 142 by bending or by forming a branch structure. Depending on the structure of the second cavity 142, the second cavity 142 can also achieve different functions. For example, the second cavity 142 can be set as a closed cavity, and the second cavity 142 can be used to form a first insertion cavity 181. The heat insulation capacity of the connection structure 100 can also be improved by filling the second cavity 142 with heat insulation material.

[0207] In some embodiments, such as Figure 22 As shown, the second cavity 142 and the first cavity 141 are along the second direction (the second direction is as follows). Figure 22 As shown by the arrow in the middle, in this arrangement, the second cavity 142 can form the first insertion slot, and the second cavity 142 can also achieve the weight reduction of the connection structure 100.

[0208] In some embodiments, such as Figure 23 As shown, the second cavity 142 and the first cavity 141 are along the first direction (the first direction is as follows). Figure 23 The arrangement (as shown by the middle arrow) should be noted. Figure 1 The connecting plate 200, which extends into the first cavity 141, is generally small in size. To prevent excessive gaps between the first cavity 141 and this part, the first cavity 141 generally does not occupy the entire dimension of the extension wall 120 in the first direction. By setting the second cavity 142 in the first direction of the extension wall 120, the space of the extension wall 120 in the first direction can be fully utilized to increase the contact area between the extension wall 120 and the connecting plate 200, so that the connecting structure 100 and the connecting plate 200 can be in more complete contact. This allows the weight of the wall panel 20 to be transferred to the connecting plate 200 more fully, further enhancing the load-bearing capacity of the connecting plate 200 and thus further improving the reliability of the external wall fixing node 10. Depending on the structure of the second cavity 142, the second cavity 142 can also achieve different functions. For example, if the second cavity 142 is set as a closed cavity, while the wall surface of the closed cavity fits more fully with the connecting plate 200, the vacuum in the closed cavity can further improve the heat insulation capacity of the connecting structure 100. It should be noted that the arrangement order of the first cavity 141 and the second cavity 142 can be arbitrary. Optionally, the first cavity 141 is closer to the fitting wall 110 than the second cavity 142, and the second cavity 142 is closer to the fitting wall 110 than the first cavity 141. At the same time, the first cavity 141 and the second cavity 142 can be arranged alternately, and the first cavity 141 and the second cavity 142 can be arranged side by side and share the same wall surface.

[0209] In some embodiments, such as Figure 23As shown, the first cavity 141 is located on the side closer to the mating surface 111. That is, in the first direction, the first cavity 141 is closer to the mating surface 111 than the second cavity 142. It should be noted that the mating surface 111 is used to fit with the wall panel 20. By placing the first cavity 141 closer to the mating surface 111, the gravity of the wall panel 20 can be transferred to the first cavity 141 through a shorter path, and the bending moment generated by the extension wall 120 itself can be reduced. This allows the first cavity 141 to convert more bending moment into tensile stress, further improving the reliability of the external wall fixing node 10.

[0210] In some embodiments, such as Figure 24 As shown, the fitting wall 110, the extension wall 120, and the branch wall 130 surround and form the first cavity 141. That is, one side of the fitting wall 110 is used to form the fitting surface 111, and the other side of the fitting wall 110 is also used to surround and form the first cavity 141, so that the first cavity 141 can be closer to the fitting surface 111, and thus the first cavity 141 can convert more bending moment into tensile stress, further improving the reliability of the external wall fixing node 10. Moreover, by forming the wall surface of the first cavity 141 through the fitting wall 110, the structure of the connection structure 100 can be made more compact, and the manufacturing cost of the connection structure 100 can be reduced.

[0211] Optional, such as Figure 23 As shown, the opening direction of the second cavity 142 is the same as the opening direction of the first cavity 141; optionally, as... Figure 25 As shown, the opening of the second cavity 142 is opposite to the opening of the first cavity 141.

[0212] In some embodiments, such as Figure 26 As shown, the second cavity 142 is a closed cavity without an opening, thus allowing the walls surrounding the second cavity 142 to connect with... Figure 1 The connecting plate 200 in the middle makes more full contact, and at the same time, by evacuating the second cavity 142, the heat insulation capacity of the connecting structure 100 can be improved.

[0213] In some embodiments, such as Figure 27 As shown, the second cavity 142 is filled with heat insulation material. By filling the second cavity 142 with heat insulation material, the heat insulation capacity of the connecting structure 100 can be improved. Optionally, when heat insulation material is provided in the second cavity 142, the second cavity 142 can have an opening, and the opening is closed by the connecting plate 200 to prevent leakage of the heat insulation material. Optionally, the second cavity 142 can be a closed cavity, so that it can have more sufficient contact with the connecting plate 200 while preventing the heat insulation material from leaking out of the second cavity 142. Moreover, there is no need to evacuate the second cavity 142, which can improve the heat insulation capacity of the connecting structure 100 in a more cost-effective way.

[0214] In some embodiments, such as Figure 24 As shown, the connecting structure 100 is a one-piece structure, and the material of the connecting structure 100 is all metal, that is, the load is directly borne by the one-piece metal structure. Figure 1 The weight of the wall panel 20 is transferred to the connecting plate 200 more reliably, thereby further improving the reliability of the external wall fixing node 10.

[0215] In some embodiments, the connection structure 100 is a split structure, for example, such as Figure 28 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, a branch wall 130, and an extension wall 120 for surrounding and forming the first cavity 141, for use with... Figure 1 The fitting wall 110 fixed to the wall panel 20, the branch wall 130 for surrounding the first cavity 141, and part of the extension wall 120 are all integrally formed, that is, for fixed connection with the wall panel 20 and for connection with... Figure 1 The portion of the connecting plate 200 that is fixedly connected forms an integral first part 151. The weight of the wall panel 20 can be reliably transferred to the connecting plate 200 through the first part 151, improving the reliability of the external wall fixing node 10. At the same time, the other parts of the extension wall 120 form a second part 152. By setting a split connecting structure 100, different materials can be used for different parts of the connecting structure 100. That is, according to the different load-bearing requirements of different parts, different materials can be set for different parts of the connecting structure 100, thereby meeting the load-bearing requirements of the connecting structure 100 while reducing the manufacturing cost of the connecting structure 100. For example, the material of the first part 151 is metal, and the material of the second part 152 is a polymer, such as nylon, plastic, or a mixture of nylon and plastic.

[0216] It should be noted that the second part 152 is used to implement different functions. Optionally, the second part 152 has a flat structure and is used in conjunction with... Figure 1 The connecting plate 200 in the middle is in full contact, thereby more fully transferring the weight of the wall panel 20 to the connecting plate 200, thus improving the reliability of the external wall fixing node 10. Optionally, the second part 152 can also form a cavity, which forms a closed cavity and / or is used to fill thermal insulation material, thereby improving the thermal insulation capacity of the connecting structure 100. The structure of the second part 152 is described below with reference to various embodiments.

[0217] In some embodiments, such as Figure 29As shown, the portion of the extension wall 120 forming the second part 152 also surrounds and forms the third cavity 143, which has an opening. The second part 152 also includes a cover plate 160, which is fixedly connected to the extension wall 120 and covers the opening of the third cavity 143, thereby forming a closed cavity. Optionally, by filling the third cavity 143 with heat insulation material, the heat insulation capacity of the connection structure 100 can be improved.

[0218] Optional, such as Figure 30 As shown, the cover plate 160 includes a cover body 161 and a support plate 162. The inner wall of the third cavity 143 forms a first snap-fit ​​structure 1431. The cover body 161 has a second snap-fit ​​structure 163, which engages with the first snap-fit ​​structure 1431, thereby engaging the cover body 161 with the extension wall 120. When the cover body 161 is engaged with the extension wall 120, the cover body 161 seals the opening of the third cavity 143. The snap-fit ​​structure allows for a detachable connection between the cover body 161 and the extension wall 120, thereby controlling the opening and closing of the third cavity 143 opening to facilitate the injection of heat insulation material into the third cavity 143. After completion, the third cavity 143 forms a closed cavity; at the same time, the support plate 162 protrudes from the outer surface of the cap body 161 and abuts against the inner wall of the third cavity 143, and the extension direction of the support plate 162 is parallel to the depth direction of the third cavity 143. It can be understood that the cap body 161 forms a suspended structure after sealing the third cavity 143. By abutting against the inner wall of the third cavity 143 with the support plate 162, it can resist the deformation of the suspended part of the cap body 161 into the third cavity 143 caused by external forces. This deformation may cause the first snap-fit ​​structure 1431 to separate from the second snap-fit ​​structure 163. By limiting this deformation with the support plate 162, the snap-fit ​​between the cap body 161 and the extension wall 120 can be made more reliable.

[0219] In some embodiments, such as Figure 31 As shown, the second part 152 surrounds and forms the fourth cavity 144, which is a closed cavity. That is, the second part 152 forms an integral closed fourth cavity 144 by bending, thereby improving the structural strength of the second part 152.

[0220] In some embodiments, the first portion 151 and the second portion 152 are detachably connected, for example, as shown in... Figure 32 As shown, the first part 151 and the second part 152 are connected by bolts, for example, as shown in the figure. Figure 33 As shown, the branch wall 130 includes a third snap-fit ​​structure 131 in the first direction (the first direction is as shown in the figure). Figure 33As shown by the middle arrow, the end of the second part 152 has a fourth snap-fit ​​structure 1521, which can engage with the third snap-fit ​​structure 131 to snap the second part 152 with the branch wall 130, that is, the first part 151 and the second part are detachably connected by snap-fit.

[0221] In some embodiments, such as Figure 34 As shown, the connection structure 100 also includes a third part 153, and the first part 151, the second part 152 and the third part 153 are in a first direction (the first direction is as shown in the figure). Figure 34 Arranged sequentially as shown by the middle arrow, the third part 153 is used to implement other extended functions of the connection structure 100, such as for fixed connection with the frame structure of the exterior wall structure. Optionally, the material of the third part 153 is metal. The third part 153 is detachably connected to the second part 152. For example, the third part 153 is connected to the second part 152 by bolts. Figure 34 As shown, in the first direction, the second part 152 has a fifth snap-fit ​​structure 1522 at the opposite end to the one with the fourth snap-fit ​​structure 1521, and the end of the third part 153 has a sixth snap-fit ​​structure 1531. The sixth snap-fit ​​structure 1531 can engage with the fifth snap-fit ​​structure 1522, thereby engaging the second part 152 and the third part 153, thereby achieving a detachable connection between the second part 152 and the third part 153.

[0222] In some embodiments, such as Figure 35 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 35 (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.

[0223] In some embodiments, such as Figure 36 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 36 (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.

[0224] Optional, such as Figure 36 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.

[0225] In some embodiments, such as Figure 37 As shown, in the second direction (the second direction is as follows) Figure 37 As indicated by the middle arrow, the bonding wall 110 extends away from the branch wall 130, and at least two separating protrusions 170 are located on both sides of the extension wall 120. By extending the bonding wall 110 away from the extension wall 120, the bonding surface 111 can have a larger area in the second direction and provide more space for the separating protrusions 170. Simultaneously, by positioning at least two protrusions on both sides of the extension wall 120 in the second direction, the bonding cavity 112 can cross the extension wall 120 in the second direction. This positioning of the bonding cavity 112 not only provides a larger bonding area but also allows the bending moments borne by the bonding surfaces 111 on both sides of the extension wall 120 to cancel each other out to a certain extent, thereby reducing the torque transmitted to the extension wall 120 and further improving... Figure 1 The reliability of fixing the wall panel 20 to the mating surface 111.

[0226] In some embodiments, such as Figure 38 As shown, in the second direction (the second direction is as follows) Figure 38 As shown by the middle arrow, at least one partition protrusion 170 is flush with the extension wall 120. By making the partition protrusion flush with the extension wall 120, the partition protrusion 170 can be formed at the same time as the extension wall 120 is formed, which reduces the manufacturing cost and manufacturing difficulty of the connection structure 100.

[0227] In some embodiments, such as Figure 39 As shown, in the second direction (the second direction is as follows) Figure 39 As indicated by the middle arrow, the bonding wall 110 extends away from the end of the branch wall 130, that is, the bonding wall 110 extends from the extension wall 120 in the second direction to a position beyond the end of the branch wall 130, thereby forming a larger bonding surface 111 and improving the bonding efficiency. Figure 1 The wall panel 20 and the mating surface 111 are fixed reliably; at the same time, at least one dividing protrusion 170 is located on the side of the end of the branch wall 130 away from the extension wall 120, that is, at least one dividing protrusion 170 is also provided in the second direction beyond the end of the branch wall 130, thereby forming a larger mating cavity 112, and the position of the wall panel 20 in the second direction can be adjusted in a larger range, thereby allowing for more flexible adjustment of the spacing between adjacent wall panels 20 in the second direction.

[0228] In some embodiments, such as Figure 40 As shown, in the second direction (the second direction is as follows) Figure 40 As indicated by the middle arrow, at least one dividing protrusion 170 is flush with the end of the branch wall 130, so that the ends of the dividing protrusion 170 and the branch wall 130 share the same positioning reference, which facilitates the manufacturing of the connection structure 100. Optionally, a support wall 183 is provided at the end of the branch wall 130, and the support wall 183 extends from the end of the branch wall 130 to the mating wall 110. The support wall 183 is parallel to a dividing protrusion 170, so that the dividing protrusion 170 can be formed at the same time as the support wall 183, which reduces the manufacturing cost and manufacturing difficulty of the connection structure 100.

[0229] This utility model embodiment also provides a connecting plate, which is used in, for example... Figure 1 The external wall fixing node 10 in the figure is a connecting plate used to connect with the wall panel through the connecting structure, and the connecting plate is used to fix the wall panel to the wall. The structure and function of the connecting plate are described below with reference to various embodiments.

[0230] In some embodiments, such as Figure 41 As shown, the connecting plate 200 includes a connecting body 210 and a fixed support plate 220. The connecting body 210 is along a third direction (the third direction is as follows: ...). Figure 41 (As shown by the middle arrow) Extends to form opposing first and second ends, the second end being used to connect with... Figure 1The wall panel 20 is fixedly connected to the wall 30. The second end can be fixed to the wall 30 in any way. For example, a first hook structure is fixed on the wall 30, and the second end forms a second hook structure that cooperates with the first hook structure. By hooking the two hook structures together, the second end can be fixedly connected to the wall 30. For example, the second end can also be directly fixed to the wall 30 by expansion bolts, and there is an adhesive structure between the wall panel 20 and the wall 30.

[0231] The fixed support plate 220 extends from the outer surface of the connecting body 210. The extension direction of the fixed support plate 220 is not parallel to a third direction, thereby causing the fixed support plate 220 to extend in a direction away from the connecting body 210. The fixed support plate 220 is used to extend into... Figures 2 to 40 In any of the connecting structures 100 shown in the diagram, within the first cavity 141, that is, in the state where the connecting plate 200 is assembled with the connecting structure 100, the connecting plate 200 is connected to the connecting structure 100 via the fixed support plate 220, and through the force between the fixed support plate 220 and the first cavity 141, the bending moment portion of the wall panel 20 applied to the connecting body 210 is converted into tensile stress. The material of the connecting plate 200 is a high-strength and tough material such as metal, and the tensile strength of this tough material is higher than its compressive strength. By setting the fixed support plate 220 and extending the fixed support plate into the first cavity 141, the stress condition of the connecting plate 200 can be optimized, the material performance advantages of the connecting plate 200 can be fully utilized, the load-bearing capacity of the connecting plate 200 can be improved, thereby improving the reliability of the external wall fixed node 10.

[0232] In some embodiments, such as Figure 41 As shown, the fixed support plate 220 extends from the outer surface of the connecting plate 200 near the first end. That is, in the fourth direction, the fixed support plate 220 is a certain distance away from the first end, and the distance between the fixed support plate 220 and the first end is less than the distance between the fixed support plate 220 and the first end. This allows a portion of the connecting plate 200 to protrude from the fixed support plate 220 in the fourth direction, and the protruding portion can extend into... Figure 1 The adjacent wall panels 20 are positioned between each other, thereby providing auxiliary support for the wall panels 20.

[0233] In some embodiments, such as Figure 42 As shown, the fixed support plate 220 extends from the first end of the connecting plate 200, that is, in the fourth direction, the first end of the connecting plate 200 does not protrude from the fixed support plate 220, and the first end of the connecting plate 200 does not extend into the fixed support plate 220. Figure 1 Between adjacent wall panels 20, the reduction Figure 1 The possibility of assembly interference between the wall panel 20 and the first end of the connecting plate 200 is reduced, and the spacing between adjacent wall panels 20 can be adjusted within a wider range.

[0234] This utility model embodiment also provides an external wall fixing node, which is used to fix the wall panel to the wall. The structure of the external wall fixing node will be described below with reference to various embodiments.

[0235] In some embodiments, such as Figure 43 As shown, the external wall fixing node 10 includes, as follows: Figures 2 to 40 The connection structure 100 shown in any of the images and such as Figure 41 or Figure 42 The connecting plate 200 shown has a fixed support plate 220 that extends into the first cavity 141 of the connecting structure 100, thereby achieving a fixed connection between the connecting plate 200 and the connecting structure 100; wherein, in the direction perpendicular to the fourth direction (the fourth direction is as follows)... Figure 43 As indicated by the middle arrow, two connecting structures 100 are located on both sides of the connecting body 210. Simultaneously, fixed support plates 220 extend from both sides of the connecting body 210 and respectively into the first cavities 141 of the two connecting structures 100. This allows the connecting plate 200 to be fixedly connected to the two connecting structures 100 located on both sides of the connecting body 210 via the fixed support plates 220. This can be understood as connecting the external wall fixing node 10 with... Figure 1 When the wall panel 20 is assembled, the two connecting structures of an external wall fixing node 10 are respectively fixedly connected to two adjacent wall panels 20, and the connecting plate 200 will be fixedly connected to the two connecting structures 100 at the same time, thereby fixing the two adjacent wall panels 20 to the wall 30.

[0236] Optional, such as Figure 43 As shown, the fixed support plate 220 extends into the first cavity 141 and is in direct contact with the inner wall of the first cavity 141, thereby directly transmitting the force through the inner wall of the first cavity 141 and the fixed support plate 220.

[0237] In some embodiments, such as Figure 44 As shown, the first cavity 141 contains a filling material, which is used to fill the gap between the inner wall of the first cavity 141 and the fixed support plate 220, so that the inner wall of the first cavity 141 can more reliably transfer the weight of the wall panel 20 to the fixed support plate 220. Optionally, the filling material is a slurry, an adhesive, or a mixture of slurry and adhesive. When the filling material includes adhesive, the filling material is not only used to fill the gap between the inner wall of the first cavity 141 and the fixed support plate 220, but also to bond the inner wall of the first cavity 141 to the fixed support plate 220, so that the inner wall of the first cavity 141 is more reliably fixed to the fixed support plate 220, thereby further improving the reliability of the external wall fixing node 10.

[0238] In some embodiments, such as Figure 45As shown, the fixed support plate 220 extends out of the end connecting the body 210 to form a free end, in the first direction (the first direction is as follows). Figure 45 As shown by the middle arrow, a second guide surface 221 is formed on both sides of the free end. Along the direction in which the fixed support plate 220 extends, the cross-sectional area of ​​the fixed support plate 220 decreases. This cross-section is a plane perpendicular to the direction in which the fixed support plate 220 extends. By setting the second guide surface 221, when filling material is injected into the first cavity 141, the second guide surface 221 can squeeze the filling material to both sides, so that the filling material applies symmetrical extrusion force to the fixed support plate 220 from both sides. Through this symmetrical extrusion force, the fixed support plate 220 can be positioned in the middle of the first cavity 141, and the extrusion force applied by the filling material to the fixed support plate 220 on both sides of the fixed support plate 220 can be kept balanced. This can achieve automatic alignment of the fixed support plate 220 in the first cavity and keep the pressure applied by the filling material on both sides of the fixed support plate 220 balanced.

[0239] In some embodiments, such as Figure 46 As shown, the external wall fixing node 10 also includes a gasket 300. The gasket has a slot and is fitted onto the outside of the fixing support plate 220 through the slot. The gasket 300 can be made of any material. For example, the material of the gasket 300 can be metal, plastic, or a mixture of the above materials. The filling material in the first cavity 141 exerts a force on the fixing support plate 220 through the gasket 300. By setting the gasket 300, a larger space can be occupied in the first cavity 141, thereby more fully filling the first cavity 141 with the filling material.

[0240] In some embodiments, such as Figure 46 As shown, in the direction in which the fixed support plate 220 extends, the end of the gasket 300 away from the fixed support plate 220 has a third guide surface 310, and in the first direction (the first direction is as follows) Figure 46As shown by the middle arrow, the end of the gasket 300 away from the fixed support plate 220 has a third guide surface 310. Along the direction of extension of the fixed support plate 220, the cross-sectional area of ​​the gasket 300 decreases. This cross-section is a plane perpendicular to the direction of extension of the fixed support plate 220. By setting the third guide surface 310, when the filling material is injected into the first cavity 141, the third guide surface 310 can squeeze the filling material to both sides, so that the filling material applies symmetrical extrusion force to the gasket 300 from both sides of the fixed support plate 220. Through this symmetrical extrusion force, the gasket 300 and the fixed support plate 220 can be positioned in the middle of the first cavity 141, and the extrusion force applied by the filling material to the gasket 300 on both sides of the gasket 300 can be kept balanced. This can achieve automatic alignment of the gasket 300 and the fixed support plate 220 in the first cavity, and can also keep the pressure applied by the filling material on both sides of the gasket 300 balanced.

[0241] In some embodiments, such as Figure 47 As shown, the slot 320 includes a plug-in portion 321 and an adhesive portion 322. The depth direction of the plug-in portion 321 is parallel to the extension direction of the fixed support plate 220 and is used to accommodate the fixed support plate 220. That is, the fixed support plate 220 can be inserted into the slot 320 along the depth direction of the plug-in portion 321 so that the gasket 300 can be fitted onto the outside of the fixed support plate 220. At the same time, the adhesive portion 322 is formed by the indentation of the inner surface of the plug-in portion 321, and the depth direction of the adhesive portion 322 is not parallel to the depth direction of the plug-in portion 321, thereby ensuring that the gasket 300 is properly seated within the inner surface of the plug-in portion 321. The surface forms a cavity with a larger volume, wherein the adhesive portion 322 contains a filling material, including a fixing adhesive. It can be understood that the filling material containing the fixing adhesive can not only be located between the gasket 300 and the inner surface of the first cavity 141 to bond the gasket 300 and the inner surface of the first cavity 141, but the filling material can also fill the adhesive portion 322, thereby bonding the fixing support plate 220 and the slot 320 through the filling material in the adhesive portion 322, further improving the fixing reliability of the slot 320 and the fixing support plate 220.

[0242] In some embodiments, such as Figure 47As shown, the insertion part 321 and the fixed support plate 220 form a clearance fit. The insertion part 321 and the fixed support plate 220 are filled with filler material. It can be understood that after the fixed support plate 220 is inserted into the insertion part 321, filler material is injected into the first cavity 141. At this time, the filler material can enter between the gasket 300 and the inner surface of the first cavity 141, thereby bonding the gasket 300 to the inner surface of the first cavity 141. The filler material can also enter the slot 320 and the space between the insertion part 321 and the fixed support plate 220 through the opening of the insertion part 321, thereby bonding the fixed support plate 220 to the slot 320. At the same time, the clearance fit between the fixed support plate 220 and the insertion part 321 also enables the position of the fixed support plate 220 to be finely adjusted and reduces the risk of assembly interference between the fixed support plate 220 and the insertion part 321.

[0243] In some embodiments, such as Figure 48 As shown, the outer surface of the gasket 300 also has a first hollow structure 330, which can accommodate more filling material, thereby enabling the gasket 300 to be more reliably bonded to the inner surface of the first cavity 141.

[0244] In some embodiments, such as Figure 48 As shown, when the gasket 300 and the connecting structure 100 are assembled, the first hollow structure 330 is located inside the first cavity 141. This can be understood as follows: after the gasket 300 is inserted into the first cavity 141 and the first hollow structure 330 is filled with filler material, the first hollow structure 330 remains inside the first cavity 141, thereby reducing the possibility of the filler material in the first hollow structure 330 leaking out of the first cavity 141 and further improving the bonding reliability between the gasket 300 and the first cavity 141.

[0245] In some embodiments, such as Figure 49 As shown, the gasket 300 includes a gasket body 340 and a limiting protrusion 350. The gasket body 340 is partially located within the first cavity 141, and the gasket body 340 has a slot 320. That is, the gasket body 340 is used to insert into the first cavity 141 and can be sleeved onto the outside of the fixed support plate 220 through the slot 320. It should be noted that the gasket body 340 can move relative to the first cavity 141 along the depth direction of the first cavity 141, that is, the depth of the gasket 300 inserted into the first cavity 141 can be adjusted, thereby allowing it to be adjusted according to the depth of the first cavity 141. Figure 1The spacing between adjacent wall panels 20 adjusts the insertion depth of the gasket 300, allowing the position of the gasket 300 to adapt to the position of the wall panel 20. Simultaneously, in the extension direction parallel to the fixed support plate 220, a limiting protrusion 350 is located at the end of the gasket body 340 and outside the first cavity 141. In the depth direction perpendicular to the first cavity 141, the outer edge of the limiting protrusion 350 is located outside the first cavity 141, allowing the limiting protrusion 350 to abut against the connecting structure 100, thus limiting the insertion depth of the gasket body 300 into the first cavity 141. When the gasket body 340 is vertically inserted into the first cavity 141, the limiting protrusion 350 prevents the gasket 300 from falling completely into the first cavity 141 under its own weight, thereby causing the slot 320 to... Figure 46 The fixed support plate in the cavity detaches, which in turn causes the inner wall of the first cavity 141 to be unable to reliably transmit the force to the fixed support plate 220.

[0246] It should be noted that the limiting protrusion 350 can extend beyond the first cavity 141 in any direction perpendicular to the depth of the first cavity 141. For example, the limiting protrusion 350 extends along... Figure 2 The first direction extends beyond the first cavity 141, thereby enabling it to communicate with... Figure 2 The branch wall 130 abuts against the branch wall; optionally, the limiting protrusion 350 can also extend into the branch wall. Figure 1 Between adjacent wall panels 20, the limiting protrusions 350 provide auxiliary support for the wall panels 20; exemplarily, the connection structure 100 also includes Figure 20 In the case of support wall 183, the limiting protrusion 350 can also be along Figure 20 The third part extends out of the first cavity 141, thereby abutting against the support wall 183.

[0247] In some embodiments, such as Figure 50 As shown, the external wall fixing node 10 also includes a filler block 600, which is located within the first cavity 141. Specifically, in the depth direction of the first cavity 141, the filler block 600 is positioned between the inner surface of the first cavity 141 and the pad 300. By placing the filler block 600 within the first cavity 141, the filler material in the first cavity 141 can be filled more completely, allowing the filler material to more reliably bond the pad 300 to the inner surface of the first cavity, and also reducing the amount of filler material used. Optionally, such as... Figure 50 As shown, the filling block 600 has a hollow structure. Specifically, the filling block 600 has a weight-reducing hole 610 inside that is not connected to the external space of the filling block 600. This allows the filling block 600 to occupy a sufficiently large space while reducing its weight, and achieves lightweighting of the external wall fixing node 10 while fully compressing the filling material.

[0248] In some embodiments, such as Figure 51 As shown, the external wall fixing node 10 also includes at least two pins 60, each pin 60 being located within the first cavity 141, wherein, in the third direction (the third direction is as follows) Figure 51 As indicated by the middle arrow, the pins 60 are spaced apart. The first cavity 141 between at least two adjacent pins 60 contains a fixing plate 220 and filling material. That is, the fixing plate 220 is fixed within the first cavity 141 by the filling material. Simultaneously, in the third direction, the filling material is sealed between two pins 60 by the pins 60, thereby reliably fixing the fixing plate 220 to the connecting structure 100 without the need for gaskets. Optionally, in the third direction, such as... Figure 51 The first cavity 141 extends from one end of the extension wall 120 to the other end, thereby allowing the first cavity 141 to penetrate the extension wall 120.

[0249] Optionally, two pins 60 form a set of pins, and multiple sets of pins are arranged at intervals along a third direction in the first cavity 141. Each set of pins 60 can be connected to the fixed support plate 220 of the connecting plate 200, so that the connecting structure 100 can be fixedly connected to multiple connecting plates 200 at the same time.

[0250] In some embodiments, such as Figure 51 As shown, in third-party direction (third-party direction such as...) Figure 51 As shown by the middle arrow, the size of the first cavity 141 is smaller than that of the extension wall 120. In the third direction, the two pins are located at both ends of the first cavity 141. It can be understood that the first cavity 141 does not penetrate the extension wall 120 in the third direction, thereby reducing the impact of the first cavity 141 on the structural strength of the connecting structure 100. At the same time, the two pins 60 are spaced apart in the first cavity 141, so that the filling material in the first cavity 141 can be sealed in the third direction and the filling material can reliably fit the fixing support plate 220 with the inner wall of the first cavity 141.

[0251] In some embodiments, such as Figure 52 As shown, the first cavity 141 includes a cavity body 1411, a pin portion 1412, and a neck 1413, in a third direction (the third direction is as follows). Figure 52 As shown by the dashed arrow, two pin portions 1412 are located on both sides of the cavity body 1411, and two necks 1413 are respectively located between the cavity body 1411 and the pin portions 1412, so as to connect the cavity body 1411 and the two pin portions 1412 through the necks 1413. In the first direction (the first direction is as shown by the dashed arrow), two pin portions 1412 are located on both sides of the cavity body 1411, and two necks 1413 are located between the cavity body 1411 and the pin portions 1412. Figure 52As shown by the solid arrow, the size of the neck 1413 is smaller than the size of the cavity body 1411 and the size of the pin portion 1412. The pin portion 1412 is used to accommodate the pin, and the cavity body 1411 is used to accommodate the fixing plate 220 and the filling material. It can be understood that by forming a size-constricted neck 1413 structure between the cavity body 1411 and the pin portion 1412, the cavity body 1411 and the pin portion 1412 can be separated in the first direction, thereby limiting... Figure 51 The pin 60 moves in the first direction within the pin portion 1412, thereby enabling the pin 60 to more reliably seal the filling material within the cavity body 141. At the same time, the neck 1413 connects the cavity body 1411 and the pin portion 1412, allowing a portion of the filling material to flow from the neck 1413 into the pin portion 1412 and more reliably fix the pin 60 within the pin portion 1412.

[0252] In some embodiments, such as Figure 53 As shown, in third-party direction (third-party direction such as...) Figure 53 As shown by the middle arrow, the connecting structure 100 has multiple spaced first cavities 141, each of which is used to accommodate the fixed support plate 220, the pin 60 and the filling material. The multiple spaced first cavities 141 enable the connecting structure 100 to be fixedly connected to multiple connecting plates 200 at the same time, and the filling materials in each first cavity 141 will not affect each other, further improving the reliability of the connection.

[0253] In some embodiments, combined with Figure 54 and Figure 55 The pin 60 has a second hollow structure 61 on its outer surface and / or the pin 60 is a hollow structure, thereby making the pin 60 lighter. In some embodiments, such as Figure 46 As shown, the external wall fixing node 10 also includes a thermal insulation pad 400. The thermal insulation pad 400 is located between the connecting body 210 and the connecting structure 100, and is used to fill the gap between the connecting body 210 and the connecting structure 100. That is, the thermal insulation pad 400 is sandwiched between the connecting body 210 and the connecting structure 100, thereby further improving the thermal insulation capacity of the external wall fixing node 10. Moreover, by adjusting the thickness of the thermal insulation pad 400, the height position of the connecting structure 100 can be finely adjusted. Optionally, such as Figure 56 As shown, the limiting protrusion 350 is along the first direction (the first direction is as follows). Figure 56 (As indicated by the middle arrow) Extending, and in the first direction, the end of the heat insulation pad 440 forms an abutment portion 441, which is used to abut against the limiting protrusion 350. In the direction perpendicular to the first direction, the abutment portion 441 is located between the branch wall 130 and the limiting protrusion 350. The thickness of the abutment portion 441 can control the depth of the pad 300 extending into the first cavity 141.

[0254] In some embodiments, combined with Figure 57 and Figure 58 The external wall fixing node also includes a thermal insulation strip 500, which is horizontal and perpendicular to the first direction (the first direction is as follows). Figure 57 As indicated by the middle arrow, the thermal insulation strip 500 is located on both sides of the connecting plate 200. This can be understood as follows: in the horizontal direction, the thermal insulation strip 500 fills the space between two adjacent external wall fixing nodes 10, thereby further improving the thermal insulation capacity of the external wall fixing nodes 10. Optionally, in the vertical direction, two connecting structures 100 are located on both sides of the connecting plate 200, forming an installation space for the connecting plate 200 between the two connecting structures 100. The shape of the thermal insulation strip 500 is the same as the shape of this installation space, thereby reducing the risk of assembly interference between the thermal insulation strip 500 and the connecting structure 100. Figure 20 In the third direction, the heat insulation strip 500 can also abut against the fixed support plate 220 and gasket 300 in the first cavity 141, thereby reducing the risk of the fixed support plate 220 and gasket 300 coming out of the first cavity 141 from the third direction.

[0255] Optionally, the thermal insulation strip 500 can be a one-piece structure, thereby improving its structural strength and thermal insulation capacity; alternatively, such as... Figure 59 As shown, the thermal insulation strip 500 includes a first thermal insulation portion 510 and a second thermal insulation portion 520, which are respectively used to cover... Figure 23 The different parts of the connecting plate 200 are described below. Figure 41 The structure of the connecting plate 200 shown further illustrates the positions covered by the first heat insulation portion 510 and the second heat insulation portion 520. To facilitate explanation, the connecting plate 200 is positioned close to... Figure 1 One side of the wall panel 20 is called the front side, and the side of the connecting plate 200 closest to the wall 30 is called the rear side. The connecting body 210 can be considered to include a first connecting part and a second connecting part. The first connecting part is located on the front side of the fixed support plate 220, and the second connecting part is located on the rear side of the fixed support plate 220. The first heat insulation part 510 covers the second connecting part, and the second heat insulation part 520 covers the first connecting part. It should be noted that by setting the heat insulation strip 500 as a split structure, it can be adapted to different structures of the connecting plate 200. Specifically, in different buildings… Figure 1The spacing between the wall panel 20 and the wall 30 is different. In order for the connecting plate 200 to adapt to different spacings between the wall panel 20 and the wall 30, the second part of the connecting body 210 can have different length dimensions. At the same time, the structure of the first part of the connecting body 210 and the fixed support plate 220 remains unchanged. On this basis, the first heat insulation part 510 used to cover the first part of the connecting body 210 has different length dimensions, and the second heat insulation part 520 used to cover the fixed support plate 220 and the second part of the connecting body 210 has a standard structure with unchanged dimensions. That is, by splicing the first heat insulation part 510 with different dimensions and the second heat insulation part 520 with unchanged dimensions, the spliced ​​heat insulation strip 500 can be adapted to the connecting plate 200 with different dimensions.

[0256] In some embodiments, Figure 43 The external wall fixing node 10 includes multiple fixing plates 700 arranged at intervals, wherein multiple connecting structures 100 are spliced ​​together to form Figure 6 The connecting frame 50 is connected to multiple connecting plates 200 to form an external wall fixing node 10, thereby enabling the connecting frame 50 to connect multiple connecting plates 200 into a whole, so that the multiple connecting plates 200 can jointly bear the load. Figure 1 The force applied to the wall panel 20 improves the reliability of the external wall fixing node 10.

[0257] This utility model embodiment also provides an exterior wall structure, which is applied to buildings. The structure and function of the exterior wall structure are described below with reference to various embodiments.

[0258] In some embodiments, such as Figure 1As shown, the exterior wall structure includes: exterior wall fixing node 10, wall panel 20, and wall body 30. The wall panel 20 is attached to the mating surface 111, and the wall body 30 is fixedly connected to the second end of the connecting body 210. This can be understood as the wall panel 20 being fixedly connected to the connecting structure 100, the connecting plate 200 being fixedly connected to the connecting structure 100, and the wall body 30 being fixedly connected to the connecting plate 200, thereby fixing the wall panel 20 and the wall body 30 together. In the vertical direction, two connecting structures 100 are fixedly connected to adjacent wall panels 20. The first end of the connecting body 210 is located between the two adjacent wall panels 20, and an adhesive structure is provided 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 interconnected by filling the adhesive structure to improve the fixing reliability between them. 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 the 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 the two adjacent wall panels 20. In this state, the fixing adhesive between the two wall panels 20 can be fixed to the first end, or the fixing adhesive may not contact the first end. Alternatively, as... Figure 1 As 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.

[0259] In some embodiments, such as Figure 60 As shown, Figure 1 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.

[0260] Optional, such as Figure 61As 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 as a whole to the side of the wall panel 20 near 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.

[0261] Optional, such as Figure 62 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 61 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.

[0262] In some embodiments, combined with Figure 63 and Figure 64 The external wall fixing node 10 also includes a thermal insulation strip 500. In the horizontal direction, the thermal insulation strip 500 is located on the side of the connecting plate 200; in the vertical direction, the thermal insulation strip 500 is located between adjacent wall panels 20. This means that the connecting plate 200 cannot completely fill the gap between two adjacent connecting plates 200 in the vertical direction, and the thermal insulation strip 500 is needed to seal the gap to improve the thermal insulation capacity of the external wall structure. Optionally, in the horizontal direction, two adjacent external wall fixing nodes 10 each have a thermal insulation strip 500, and the two thermal insulation strips 500 abut against each other, thereby sealing the gap between the two connecting plates 200 through the two thermal insulation strips 500; optionally, in the horizontal direction, two adjacent external wall fixing nodes 10 share one thermal insulation strip 500; optionally, in the vertical direction, the gap between adjacent connecting plates 200 is sealed by... Figure 25 The insulation layer 42 is filled in to improve the insulation capacity of the exterior wall structure; among which, such as Figure 63 As shown, a portion of the structure of the fixing plate 700 can extend between adjacent wall panels 20 to provide auxiliary support for the wall panels 20, such as... Figure 64 As shown, the fixing plate 700 may not extend between adjacent wall panels 20, so that the gap between adjacent wall panels 20 can be adjusted to a smaller size.

[0263] In some embodiments, such as Figure 65As shown, the external wall fixing node 10 also includes pins 60 located in the first cavity 141. At least two pins 60 are located on both sides of the fixing support plate 220 in a third direction, so that filling material is sealed between the two pins 60 through the pins 60, and the fixing support plate 220 is reliably connected to the inner wall of the first cavity 141 through the filling material. In the vertical direction, the first cavity 141 in the lower connecting structure 100 is filled with filling material. This can be understood as two connecting structures 100 being fixedly connected to a connecting plate 200 in the vertical direction. Figure 47 The fixing support plate 220 of the connecting plate 200 extends into the first cavity 141 of the upper and lower connecting structures 100 respectively. Only the first cavity 141 of the lower connecting structure 100 is filled with filling material, thereby fixing the lower connecting structure to the connecting plate 200 through the filling material. That is, the connecting support plate 220 is fixedly connected to the lower connecting structure 100 through the filling material. The connecting support plate 220 is fixedly connected to the upper connecting structure through the cooperation with the first cavity 141. At the same time, the pin 60 is inserted into both the first cavity 141 of the lower connecting structure 100 and the first cavity 141 of the upper connecting structure 100. That is, after the lower connecting structure 100 is positioned, the upper connecting structure 100 is also connected to the lower connecting structure 100 through the pin 60, thereby realizing the positioning of the upper connecting structure 100.

[0264] Optionally, the pin 60 forms an interference fit with the first cavity 141 of the lower connecting structure 100, thereby enabling the pin 60 to more reliably seal the filling material in the first cavity 141. At the same time, the pin 60 forms an overfit or clearance fit with the first cavity 141 of the upper connecting structure 100, thereby allowing the position of the connecting structure 100 to be finely adjusted within a small range after the first cavity 141 of the upper connecting structure 100 is fitted over the pin 60.

[0265] In some embodiments, such as Figure 66 As shown, in the vertical direction, the top of the pin 60 has a fourth guide surface 62. From bottom to top, the cross-sectional area of ​​the pin 60 decreases, and the cross-section is a plane perpendicular to the vertical direction. By forming a gradually narrowing guide structure at the top of the pin 60, it is easier to fit the first cavity 141 of the upper connecting structure 100 onto the top of the pin 60, reducing the risk of assembly interference between the pin 60 and the first cavity 141. Optionally, the fourth guide surface 62 can be a guide slope or a guide curved surface.

[0266] In some embodiments, such as Figure 67As shown, in the horizontal direction, a wall gap 21 is formed between the two wall panels 20. Two external wall fixing nodes 10 are located on both sides of the wall gap 21, and the two external wall fixing nodes 10 are fixedly connected to the two wall panels 20 in the horizontal direction. It can be understood that in the horizontal direction, the two wall panels 20 are fixedly connected by two independent external wall fixing nodes 10, which facilitates the assembly of the wall panels 20 and the external wall fixing nodes 10.

[0267] In some embodiments, such as Figure 68 As shown, in the horizontal direction, a wall joint 21 is formed between the two wall panels 20. Two external wall fixing nodes 10 are located on both sides of the wall joint 21, and the two external wall fixing nodes 10 cross the wall joint 21 and are fixed together. This can be understood as the two external wall fixing nodes 10 located on both sides of the wall joint 21 forming a two-in-one structure in the horizontal direction, thus creating a more reliable structure at the wall joint 21 and improving the structural stability of the external wall structure. It should be noted that, according to the fixing plate 700 and... Figure 1 The connection methods of the middle wall 30 are different, and the forms in which the two external wall fixing nodes 10 are fixed together are different. The following will combine these with... Figures 68 to 71 An illustrative example is provided for a structural form in which two external wall fixed nodes are fixed into one.

[0268] like Figure 69 As shown, the external wall fixing node 10 also includes a fixing plate 700, and the connecting plate 200 is fixedly connected to the wall 30 through the fixing plate 700, as shown. Figure 68 As shown, two connecting plates 200 are fixedly connected to two fixing plates 700. Both fixing plates 700 are fixedly connected to the wall 30, and the two fixing plates 700 span the wall joint 21 and are integrally formed. Figure 70 As shown, the connecting plate 200 is directly fixed to the wall 30, as... Figure 71 As shown, two connecting plates 200 span the wall gap 21 and are fixed together. It should be noted that the connecting plates 200 span the wall gap 21 and are simultaneously connected to the connecting structures 100 in both connecting frames 50, and the connecting plates 200 are connected via... Figure 65 When the connection structure 100 is connected in the manner shown, that is, when the connecting plate 200 is connected to the connecting plate 200 by a filling material and the filling material is sealed between the two pins 60, a sealing structure needs to be provided at the end of the connecting structure 100. This sealing structure allows the fixed support plate 220 to pass through and, after the fixed support plate 220 is assembled, seals the filling material in the first cavity 141 together with the fixed support plate 220.

[0269] In some embodiments, such as Figure 72As shown, a wall gap 21 is formed between two wall panels 20. A connecting plate 200 of a single external wall fixing node 10 spans the wall gap 21, and the external wall fixing node 10 is simultaneously fixedly connected to two wall panels 20 in the horizontal direction. The external wall fixing node 10 includes a connecting plate 200 and at least two connecting structures 100. The connecting plate 200 and... Figure 1 The wall 30 is directly fixedly connected, and the two connecting structures 100 are fixedly connected to the two wall panels 20 respectively. The connecting plate 200 spans the wall gap 21 and the connecting plate 210 is fixedly connected to the two connecting structures 100.

[0270] In some embodiments, such as Figure 73 As shown, a wall gap 21 is formed between two wall panels 20. A connecting structure 100 of a single external wall fixing node 10 spans the wall gap 21, and the external wall fixing node 10 is simultaneously fixedly connected to the two wall panels 20 in the horizontal direction. The external wall fixing node 10 includes a connecting plate 200, a fixing plate 700, and two connecting structures 100. The two connecting structures 100 are respectively located on both sides of the wall panel 20 fixedly connected. Both the connecting plate 200 and the fixing plate 700 span the wall gap 21, and the connecting plate 200 is fixedly connected to the two connecting structures 100.

[0271] In some embodiments, such as Figure 74 As shown, Figure 1 The external wall fixing node 10 includes multiple connecting structures 100, which are spliced ​​together to form a connecting frame 50. The connecting frame 50 encloses a closed shape and is fixedly connected to the wall panel 20. This means that the wall panel 20 is fixedly connected to multiple connecting plates 200 through the connecting frame 50, thereby enabling the multiple connecting plates 200 to jointly bear the load applied by the wall panel 20, thus improving the reliability of the external wall structure. It should be noted that the closed shape formed by the connecting frame 50 can be any planar shape, such as a polygon or a circle.

[0272] In some embodiments, such as Figure 75 As shown, the exterior wall structure also includes a filling layer 40, which includes a protective layer 43. Meanwhile, adjacent connecting structures 100 in the connecting frame 50 are connected via... Figure 7 The corner bracket 51 is fixedly connected, and different parts of the corner bracket 51 are respectively fixedly connected to the adjacent connecting structure 100, so that the adjacent connecting structures 100 can be spliced ​​to form a connecting frame 50. The protective layer 43 covers the connection position between the connecting structure 100 and the corner bracket 51, thereby protecting the corner bracket 51 and improving the structural reliability of the connecting frame 50. Optionally, such as... Figure 75As shown, the filling layer 40 also includes an adhesive layer 41 and an insulation layer 42. The adhesive layer 41, the insulation layer 42 and the protective layer 43 are arranged in sequence from the wall panel 20 to the wall 30. The adhesive layer 41 is directly fixed to the side of the wall panel 20 closest to the wall 30.

[0273] In some embodiments, such as Figure 76 As shown, the exterior wall structure also includes an infill layer 40, which includes a protective layer 43, and the connection structure 100 is located away from the infill layer 40. Figure 1 The end of the wall panel 20 has a hook-shaped portion 195, which surrounds and forms a receiving cavity 196. The opening of the receiving cavity 196 is parallel to the vertical direction, and part of the protective layer 43 is located within the receiving cavity 196. It can be understood that the support and inner hook provided by the hook-shaped portion 195 to the protective layer enable a tighter bond between the protective layer 43 and the insulation layer 42, thereby making the structure of the filling layer 40 more reliable. Optionally, such as... Figure 76 As shown, the filling layer 40 also includes an adhesive layer 41 and an insulation layer 42. The adhesive layer 41, the insulation layer 42 and the protective layer 43 are arranged in sequence from the wall panel 20 to the wall 30. The adhesive layer 41 is directly fixed to the side of the wall panel 20 closest to the wall 30.

[0274] In some embodiments, such as Figure 7 As shown, the closed shape formed by the connecting frame 50 is a rectangle. At the corners of the rectangle, the connecting frame 50 is fixedly connected to four adjacent external wall fixing nodes 10. This can be understood as follows: the wall panel 20 is generally a cube, and multiple external wall fixing nodes 10 are arranged at intervals around the outer edge of the wall panel 20, thus arranging the external wall fixing nodes 10 along the rectangle. Setting the closed shape formed by the connecting frame 50 as a rectangle allows the extension direction of the connecting frame 50 to be compatible with the arrangement direction of each external wall fixing node 10, thereby facilitating the fixed connection between the connecting frame 50 and each external wall fixing node 10. It should be noted that the closed shape formed by the connecting frame 50 can be adaptively changed depending on the shape of the wall panel 20. For example, when the wall panel 20 is a hexagonal prism, the closed shape formed by the connecting frame 50 is a hexagon.
