[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0051] In the following specific embodiments, the wall panels in the exterior wall structure can be made of any material. For example, the wall panels can be one or more combinations of wall panels, tempered glass panels, ceramic tiles, stone slabs, and concrete slabs. The wall panels can be fixed to the wall in a dry-hanging manner, a wet-hanging structure, or a combination of both. Depending on the specific structure of the exterior wall structure, it can be used to achieve various functions. For example, a thermal insulation layer can be used in the exterior wall structure to achieve thermal insulation or heat preservation; a vacuum insulation layer can be used to achieve sound insulation; and wall decorations can be added to the exterior wall structure to enhance its aesthetics. The above structures can also be used in combination to enable the exterior wall structure to achieve multiple functions simultaneously. The following examples, in conjunction with various embodiments, provide exemplary descriptions of different components in the exterior wall structure and the overall structure of the exterior wall structure.

[0052] First, combine Figure 1 The usage environment of the exterior wall structure should be described, such as... Figure 1 As shown, the exterior wall structure includes an exterior wall fixing node 10, wall panels 20, and a wall 30. The wall 30 is the interior wall structure of the building. The wall panels 20 are fixedly connected to the wall 30 through the exterior wall fixing node 10. Multiple wall panels 20 are arranged side by side to cover the wall 30. The exterior wall fixing node 10 includes a connecting structure 100 and a connecting plate 200. The connecting structure 100 is used to fix the wall panels 20, and the connecting plate 200 is used to fix the wall 30. At the same time, the connecting structure 100 and the connecting plate 200 are fixedly connected to fix the wall panels 20 and the wall 30. The structure and function of the connecting structure 100 and the connecting plate 200 in the exterior wall fixing node 10 will be described by way of example in conjunction with various embodiments.

[0053] In some embodiments, such as Figure 2 As shown, the connection structure 100 includes: a mating wall 110 and an extension wall 120. The outer surface of one side of the mating wall 110 forms a mating surface 111. The extension wall 120 extends from the surface of the mating wall 110 opposite to the mating surface 111, and the extension wall 120 extends along a first direction (the first direction is as follows...). Figure 2 (As indicated by the middle arrow) extends, thereby extending the extension wall 120 to a position away from the mating surface 111, thus allowing the extension wall 120 to... Figure 1 There is a larger assembly space between the connecting plates 200 in the middle.

[0054] At the same time, the bonding surface 111 is used to... Figure 1 The wall panel 20 is fixedly connected. Specifically, the mating surface 111 forms a mating cavity 112, which has an opening 113. The depth direction of the mating cavity 112 is aligned with the first direction, that is, in the assembled state with the wall panel 20, the opening of the mating cavity 112 faces the first direction. Figure 1The wall panel 20 has a bonding cavity 112 for accommodating structural adhesive, and the bonding surface 111 is bonded to the wall panel 20 by the structural adhesive. It should be noted that if... Figure 1 In the original design, the wall panel 20 is directly bonded to the bonding surface 111. However, the structural adhesive between the wall panel 20 and the bonding surface 111 is insufficient in thickness. Furthermore, under the pressure between the wall panel 20 and the bonding surface 111, the structural adhesive spreads significantly and may even be squeezed out of the contact space between the bonding surface 111 and the wall panel 20, resulting in insufficient reliability of the fixation between the wall panel 20 and the connecting structure 100. By providing a bonding cavity 112, the bonding surface 111 can accommodate more structural adhesive and concentrate it within the contact space between the bonding surface 111 and the wall panel 20. This allows more structural adhesive to participate in the fixation connection between the bonding surface 111 and the wall panel 20, while also preventing the adhesive from being squeezed out of the contact space. This ensures a more reliable bond between the bonding surface 111 and the wall panel 20, further improving the reliability of the external wall fixing node 10. For example, Figure 2 As shown, 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 protruding from the bonding surface 111.

[0055] This utility model embodiment provides a connection structure applied to an exterior wall structure. The connection structure includes: an adhesive wall having an adhesive surface, and an extension wall extending along a first direction from the side of the adhesive wall opposite to the adhesive surface, the first side not being parallel to the adhesive surface; wherein, the adhesive surface forms an adhesive cavity, the adhesive cavity having an opening and the depth direction of the adhesive cavity being parallel to the first direction, the adhesive cavity being filled with structural adhesive, and the adhesive surface being bonded to the wall panel in the exterior wall structure through the structural adhesive in the adhesive cavity. By setting the adhesive cavity, the adhesive surface can accommodate more structural adhesive and concentrate the structural adhesive in the space where the adhesive surface and the wall panel are in contact, which not only allows more structural adhesive to participate in the fixed connection between the adhesive surface and the wall panel, but also restricts the structural adhesive from being squeezed out of the contact space between the adhesive surface and the wall panel, thereby enabling the adhesive surface to bond more reliably to the wall panel, further improving the reliability of the exterior wall fixing node.

[0056] In some embodiments, such as Figure 3 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 3(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.

[0057] Optional, such as Figure 3 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.

[0058] In some embodiments, such as Figure 4 As shown, Figure 1 The connecting plate 200 is attached to the extension wall 120, and the connecting plate 200 is fixedly connected to the extension wall 120 through a connector, thereby simplifying the structure of the connecting structure 100 and reducing the manufacturing cost of the connecting structure 100.

[0059] In some embodiments, such as Figure 5 As shown, the connecting structure 100 also includes a branch wall 130, which extends from the outer surface of the extension wall 120. That is, the branch wall 130 extends in a direction not parallel to the extension wall 120. The branch wall 130 and the extension wall 120 together form a first cavity 141. In the first direction, the mating surface 111 and the first cavity 141 are located on opposite sides of the mating wall 110, and the opening of the first cavity 141 faces a second direction (as shown in the diagram). Figure 5 (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 1The 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 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 is under stress. In the case of compression, the tensile capacity of a tough material is greater than its compressive capacity. By setting the first cavity 141, the bending moment portion 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.

[0060] In some embodiments, such as Figure 6 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.

[0061] In some embodiments, such as Figure 7 As shown, the extension wall 120 surrounds and forms a slot 121. The opening direction of the slot 121 is not parallel to the mating surface 111. The slot 121 is used to accommodate the fixing edge 22 of the wall panel 20. It can be understood that... Figure 1The wall panel 20 is a wall panel including a panel body 21 and a fixed edge 22. The fixed edge 22 extends along the thickness direction of the panel body 21. By inserting the fixed edge 22 into the slot 121, the wall panel 20 can be attached to the fitting wall 110 through the fitting surface 111, and simultaneously inserted into the extension wall 120 through the slot 121. That is, not only does the adhesive force between the fitting surface 111 and the wall panel 20 bear the tangential force between the wall panel 20 and the connecting structure 100, but the force between the fixed edge 22 and the slot 121 also bears the bending moment exerted by the wall panel 20 on the connecting structure 100. This makes the fixation of the wall panel 20 and the connecting structure 100 more reliable and reduces the risk of the wall panel 20 falling off.

[0062] Optional, such as Figure 7 As shown, the connecting plate 200 is attached to the extension wall 120, and the connecting plate 200 is fixedly connected to the extension wall 120 through a connector, thereby fixing the connecting plate 200 to the wall panel 20. This connection structure 100 has a simple structure and can reduce the manufacturing cost of the connection structure 100.

[0063] Optional, such as Figure 8 As shown, the extension wall 120 and the branch wall 130 surround and form a first cavity 141. At least a portion of the connecting plate 200 extends into the first cavity 141. That is, while the wall panel 20 is fixedly connected via the mating surface 111 and the slot 121, the connecting plate 200 is connected to the connecting structure 100 via the first cavity 141. This allows the weight of the wall panel 20 to be transferred to the connecting plate 200 more reliably, improving the connection between the wall panel 20 and the connecting structure 100. Figure 1 The fixing reliability of the external wall fixing node 10; wherein, the slot 121 and the first cavity 141 are arranged along the first direction, and the first cavity 141 is located away from the slot 121. Figure 1 This reduces the risk of assembly interference between the wall panel 20 and the connecting plate 200.

[0064] In some embodiments, such as Figure 7 As shown, the opening direction of the slot 121 is parallel to the first direction. When the slot 121 is assembled with the wall panel 20, the opening of the slot 121 can be made parallel to the horizontal direction. This allows the supporting force applied between the inner wall of the slot 121 and the fixed edge 22 to be parallel to the vertical direction. This enables the supporting force to more effectively resist the gravity of the wall panel 20, thereby further improving the fixing reliability of the connection structure 100 and the wall panel 20 and further reducing the risk of the wall panel 20 falling off.

[0065] In some embodiments, such as Figure 9As shown, the slot 121 includes multiple receiving portions 122. That is, the multiple receiving portions 122 do not directly form an integral structure, but are formed separately as multiple receiving portions 122. Each receiving portion 122 can be separately formed, thereby reducing the manufacturing difficulty and manufacturing cost of the slot 121. Moreover, the multiple fixed edges 22 form a plug-in structure with the multiple receiving portions 122, which can further improve the fixing reliability.

[0066] In some embodiments, such as Figure 10 As 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. While the wall 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.

[0067] Optional, such as Figure 10 As shown, the extension wall 120 also surrounds and forms a second cavity 142, the second cavity 142 and the first cavity 141 along a first direction (the first direction is as follows). Figure 10 The arrangement (as shown by the middle arrow) should be noted. Figure 1 The connecting plate 200, which is used to extend into the first cavity 141, is generally small in size. In order to prevent the first cavity 141 from forming an excessive gap with 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 sufficient contact, thereby transferring the weight of the wall panel 20 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. 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.

[0068] In some embodiments, such as Figure 11 As shown, the fixed edge 22 and the extension wall 120 surround and form a partial fixed connection to the second cavity 142. This can be understood as the second cavity 142 not only providing thermal insulation for the connection structure but also offering sufficient installation space for the fixed edge 22 and the connection structure 100. Specifically, in... Figure 1 When the connecting plate 200 and the connecting structure 100 are assembled, the first cavity 141 needs to accommodate the fixed support plate 120, thus the first cavity 141 cannot provide installation space for the fixed edge 22. The second cavity 142 does not need to accommodate other rigid structures. The part of the second cavity 142 formed by the surrounding of the extension wall 120 provides installation space for the fixed edge 22. There will be no problem of assembly interference between other rigid structures and the fixed edge 22. By making the second cavity 142 closer to the mating surface 111, the second cavity 142 can be closer to the wall panel 20 when the wall panel 20 and the connecting structure 100 are assembled, thereby facilitating the fixed connection between the fixed edge 22 and the extension wall 120.

[0069] It should be noted that the fixed edge 22 can be fixedly connected to the extension wall 120 in any way. For example, the fixed edge 22 is partially fixedly connected to the second cavity 142 formed by the extension wall 120 through a snap-fit ​​structure. For example, the fixed edge 22 is partially fixedly connected to the second cavity formed by the extension wall 120 through adhesive bonding.

[0070] In some embodiments, such as Figure 11 As shown, the fixed edge 22 is partially fixedly connected to the second cavity 142 formed by the extension wall 120 through the connector 300, and the connector 300 extends into the second cavity 142. It can be understood that by setting the connector 300 to partially fix the fixed edge 22 to the second cavity 142 formed by the extension wall 120, not only can the outer surface of the extension wall 120 be used to fix the fixed edge 22, but also the internal space of the second cavity 142 can provide fixing space for the fixed edge 22 by extending the connector 300 into the second cavity 142. This makes fuller use of the structure of the extension wall 120 to provide a larger installation space for the fixed edge 22, thereby further improving the fixing reliability of the fixed edge 22 and further reducing the risk of the wall panel 20 falling off. The connector 300 can be a fixing screw or a rivet.

[0071] In some embodiments, such as Figure 12 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. At the same time, by evacuating the second cavity 142, the heat insulation capacity of the connecting structure 100 can be improved. Moreover, since the closed cavity has no opening, the part of the extension wall 120 surrounding the second cavity 142 can more easily form an outer surface that fits with the fixed edge 22, further improving the fixing reliability of the wall panel 20 and the connecting structure 100 and further reducing the risk of the wall panel 20 falling off.

[0072] In some embodiments, such as Figure 13As shown, the second cavity 142 is filled with a filler material. Depending on the filler material, the second cavity 142 can have different functions. When the filler material includes a fixing adhesive, and the connector 300 in the figure extends into the second cavity 142, the filler material can bond with the part of the connector 300 that extends into the second cavity 142, thereby further improving the fixing reliability of the fixing edge 22 and the connecting structure 100 and further reducing the risk of the wall panel 20 falling off.

[0073] Optionally, the filler material includes a thermal insulation material, thereby providing better thermal insulation to the connection structure 100. Alternatively, the filler material includes a mixture of thermal insulation material and a fixing adhesive, thereby improving the thermal insulation of the second cavity 142 while simultaneously enhancing the thermal insulation performance of the filler material through the fixing adhesive. Figure 12 The connector 300 is fixed in place, thereby further improving the fixing reliability between the fixed edge 22 and the connecting structure 100 and further reducing the risk of the wall panel 20 falling off.

[0074] In some embodiments, such as Figure 14 As shown, the extension wall 120 also surrounds and forms a third cavity 143. This can be understood as the extension wall 120 forming the third cavity 143 by bending or by forming a branch structure. The third cavity 143 and the first cavity 141 are along a first direction (the first direction is as follows). Figure 14 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 a third cavity 143 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 third cavity 143, it can also achieve different functions. For example, if the third cavity 143 is set as a closed cavity, while the wall surface of the closed cavity fits more fully with the connecting plate 200, the vacuum inside 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 third cavity 143 can be arbitrary. Optionally, the first cavity 141 is closer to the fitting wall 110 than the third cavity 143, and the third cavity 143 is closer to the fitting wall 110 than the first cavity 141. At the same time, the first cavity 141 and the third cavity 143 can be arranged alternately, and the first cavity 141 and the third cavity 143 can be arranged side by side and share the same wall surface.

[0075] In some embodiments, such as Figure 15 As 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 third cavity 143. 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.

[0076] In some embodiments, such as Figure 16 As shown, the third cavity 143 is a closed cavity without an opening, thus allowing the walls surrounding the third cavity 143 to interact with... Figure 1 The connecting plate 200 in the middle makes more full contact, and at the same time, by evacuating the third cavity 143, the heat insulation capacity of the connecting structure 100 can be improved.

[0077] In some embodiments, such as Figure 17 As shown, the third cavity 143 is filled with heat insulation material. By filling the third cavity 143 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 third cavity 143, the third cavity 143 may have an opening, and the opening is closed by the connecting plate 200 to prevent leakage of the heat insulation material. Optionally, the third cavity 143 may be a closed cavity, so that it can make more full contact with the connecting plate 200 while preventing the heat insulation material from leaking out of the third cavity 143. Moreover, there is no need to evacuate the third cavity 143, which can improve the heat insulation capacity of the connecting structure 100 in a more cost-effective way.

[0078] In some embodiments, such as Figure 16 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.

[0079] In some embodiments, such as Figure 18 As shown, the connection structure 100 includes a first part 151 and a second part 152. The first part 151 includes a fitting wall 110 and a partial extension wall 120, which can be understood as being used for... Figure 1 The wall panel 20, the mating surface 111, and a portion of the extended wall 120 form an integral first part, thereby improving the connection structure 100 with... Figure 1 The fixing reliability of the middle wall panel 20 is achieved by setting a split connection structure 100, which allows different materials to be used for different parts of the connection structure 100. That is, different materials are set for different parts of the connection structure 100 according to the different load-bearing requirements of different parts, thereby meeting the load-bearing requirements of the connection structure 100 while reducing the manufacturing cost of the connection 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.

[0080] Depending on the structure of the connecting structure 100, different parts of the extension wall 120 form the first part 151, which will be discussed below in conjunction with... Figure 19 and Figure 20 The structure of the first part 151 will be explained.

[0081] like Figure 19 As shown, the first portion 151 includes: a portion of the fitting wall 110, a branch wall 130, and an extension wall 120 for surrounding the formation of 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 connecting plate 200 in the middle is fixedly connected to form an integral first part 151. The gravity of the wall panel 20 can be reliably transferred to the connecting plate 200 through the first part 151, which improves the reliability of the external wall fixed node 10.

[0082] like Figure 20 As shown, the first portion 151 includes: a portion of the fitting wall 110 and the extending wall 120 for surrounding the forming slot 121, the first portion 151 being used with... Figure 1 The wall panel 20 is fixedly connected in the connection structure 100. Specifically, the mating surface 111 is fixedly connected to the wall panel 20 by adhesive, and the slot 121 and the second cavity 142 are fixedly connected to the fixed edge 22 of the wall panel 20. Figure 1 The first part 151, which is a whole formed by the fixed connection of different parts of the wall panel 20, can improve the fixing reliability of the connection structure 100 and the wall panel 20.

[0083] Optional, such as Figure 21 As shown, the first part 151 includes: a portion of the fitting wall 110, a branch wall 130, and an extension wall 120 for surrounding the forming slot 121 and a portion of the extension wall 120 for surrounding the forming first cavity 141, that is, the first part 151 includes both the first cavity 141 and the slot 121.

[0084] 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.

[0085] In some embodiments, such as Figure 22 As shown, the first part 151 of the extension wall 120 also surrounds and forms a fourth cavity 144, 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 fourth cavity 144, thereby forming a closed cavity. Optionally, by filling the fourth cavity 144 with heat insulation material, the heat insulation capacity of the connection structure 100 can be improved.

[0086] Optional, such as Figure 23 As shown, the cover plate 160 includes a cover body 161 and a support plate 162. The inner wall of the fourth cavity 144 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 fourth cavity 144. 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 fourth cavity 144 to facilitate the injection of heat insulation material into the fourth cavity 144. After completion, the fourth cavity 144 becomes 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 fourth cavity 144. The extension direction of the support plate 162 is parallel to the depth direction of the fourth cavity 144. It can be understood that the cap body 161 forms a suspended structure after sealing the fourth cavity 144. By abutting against the inner wall of the fourth cavity 144 with the support plate 162, it can resist the deformation of the suspended part of the cap body 161 into the fourth cavity 144 caused by external forces. This deformation may cause the first snap-fit ​​structure 1431 and the second snap-fit ​​structure 163 to separate. 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.

[0087] In some embodiments, such as Figure 24As shown, the second part 152 surrounds and forms the fifth cavity 145. The fifth cavity 145 is a closed cavity; that is, the second part 152 forms a closed fifth cavity 145 by bending, thereby improving the structural strength of the second part 152. It should be noted that... Figure 24 The second part 152 shown can correspond to the first part 151 in various structures. For example, the first part 151 can be... Figures 18 to 21 The first part 151 shown in any of the images.

[0088] In some embodiments, the first portion 151 and the second portion 152 are detachably connected, for example, as shown in... Figure 25 As shown, the first part 151 and the second part 152 are connected by bolts, for example, as shown in the figure. Figure 26 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 26 As 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.

[0089] In some embodiments, such as Figure 27 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 27 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 27 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, thus achieving a detachable connection between the second part 152 and the third part 153.

[0090] In some embodiments, such as Figure 28 As shown, the third cavity 143 has an opening, and the opening of the third cavity 143 is in the opposite direction to the opening of the first cavity 141. By making the third cavity 143 have an opening facing the opposite direction to the first cavity 141, the extension wall 120 can have a larger flat plate portion, thereby enabling it to... Figure 1The connecting plate 200 fits reliably, making it easier for the third cavity 143 to accommodate the insulation material.

[0091] In some embodiments, such as Figure 29 As shown, the third cavity 143 and the first cavity 141 are along the second direction (the second direction is as follows). Figure 29 (As shown by the middle arrow) The first cavity 141 is capable of accommodating Figure 1 While fixing the support plate 220 of the connecting plate 200, the third cavity 143 can achieve the weight reduction of the connecting structure. Optionally, when multiple connecting structures 100 need to be spliced ​​together to form a connecting frame, and adjacent connecting structures 100 in the connecting frame need to be connected by corner groups, the third cavity 143 can be used as a plug slot for inserting into the corner group.

[0092] In some embodiments, such as Figure 30 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 30 As shown by the solid arrow in the middle, the support wall 182 is fixed to the end of the branch wall 130, and in a third direction (such as...). Figure 30As indicated by the dashed arrow, two support walls 183 are located at both ends of the branch wall 183. This can be understood as the support walls 183, branch wall 130, and extension wall 120 surrounding and forming a connecting cavity. This connecting cavity has an opening in the second direction. When multiple connecting structures 100 need to be joined together to form a connecting frame, the connecting cavity accommodates the corner assembly. Furthermore, since the support walls 183 provide a supporting plane, they can be placed on an automatic corner assembly device, facilitating the automatic corner assembly device to automatically join multiple connecting structures 100 to form a connecting frame. Specifically, during the process of assembling the connecting structure 100 and the corner brackets to form a connecting frame using an automated splicing device, the connecting structure 100 can be stably placed on the assembly station of the automated splicing device by the support structure of the support wall 183 and the second insertion cavity 182. At this assembly station, the automated splicing device can automatically insert the corner brackets into the two connecting structures 100, and can also automatically insert the connecting screws along the second direction from the support wall 183 and the support structure into the connecting structure 100 and the corner brackets, thereby automatically splicing multiple connecting structures 100 to form a connecting frame. 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 can be arranged along the first direction, or the first insertion cavity 181 and the first cavity 141 can be arranged along the second direction. Optionally, the first insertion cavity 181 and the first cavity 141 are arranged along a third direction, with the two first insertion cavities 181 located on both sides of the first cavity 141 and communicating with 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 that extends through the extension wall 120 along a third direction. The initial cavity has a support wall 183 that extends from one end of the extension wall 120 to the other end in the third direction, thereby forming two openings of the first insertion cavity 181 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.

[0093] In some embodiments, such as Figure 31 As shown, in the second direction (the second direction is as follows) Figure 31As 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.

[0094] In some embodiments, such as Figure 32 As shown, in the second direction (the second direction is as follows) Figure 32 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.

[0095] In some embodiments, such as Figure 33 As shown, in the second direction (the second direction is as follows) Figure 33 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.

[0096] In some embodiments, such as Figure 34 As shown, in the second direction (the second direction is as follows) Figure 34As 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.

[0097] In some embodiments, such as Figure 35 As shown, the inner surface of the first cavity 141 has adhesive protrusions 1411. Multiple adhesive protrusions 1411 are spaced apart on the inner surface of the first cavity 141. By providing adhesive protrusions 1411, the surface area of ​​the inner surface of the first cavity 141 can be increased, thereby allowing the first cavity 141 to more fully bond with… Figure 1 The fixed support plate 220 is bonded, which is optional, such as... Figure 36 As shown, the connection structure 100 also includes a slot.

[0098] In some embodiments, such as Figure 37 As shown, the connection structure 100 is far away from Figure 2 One end of the fitting wall 110 has a hook-shaped structure 191, the opening of which faces a second direction (such as...). Figure 37 (As indicated by the middle arrow) can be understood as... Figure 1 The exterior wall structure includes a filling layer, which includes an insulation layer and a protective layer. The insulation layer is fixed to the side of the wall panel 20 near the wall 10, and the protective layer is fixed to the side of the insulation layer near the wall 10. The protective layer covers the end of the connecting structure 100 away from the adhesive wall 110, and the hook-shaped part 191 can hook the protective layer so that the protective layer can be tightly attached to the end.

[0099] In some embodiments, such as Figure 38 As shown, the end of the connecting structure 100 away from the fitting wall 110 has a guide groove 192. When multiple connecting structures 100 need to be spliced ​​together to form a connecting frame using corner brackets, some corner brackets are accommodated in the guide groove 192, thus facilitating the installation of the corner brackets and the assembly of the connecting frame. The cross-sectional area of ​​the guide groove 192 decreases from the end of the connecting structure 100 away from the fitting wall 110 towards the fitting wall 110. This cross-section is perpendicular to a first direction (such as...). Figure 38 As indicated by the middle arrow, the guide groove 192 has a guide slope to reduce the area of ​​the guide groove 192 along the depth direction, thereby making it easier to install the corner bracket to the target position during the process of inserting the corner bracket into the guide groove 192.
