[0175] In the following specific embodiments, the metal plate in the metal outer wall can be any metal capable of playing a protective role, which can be iron, aluminum, etc., or an alloy formed by multiple metals; the fixing mode of the metal plate in the metal outer wall and the wall body can be dry hanging, wet hanging structure, or part dry hanging and part wet hanging. According to the specific structure of the metal outer wall structure, the metal outer wall structure can be used to realize various different functions, for example, using a heat insulation filling layer in the metal outer wall structure, the metal outer wall structure is used to realize heat insulation or heat preservation, for example, using a vacuum isolation layer in the metal outer wall structure, the metal outer wall structure is used to realize sound insulation, for example, adding a wall decoration piece in the metal outer wall structure, the metal outer wall structure can also be used to improve the aesthetics of the building, and the above structures can also be combined for use, so that the metal outer wall structure realizes multiple functions at the same time. The different components in the metal outer wall structure and the overall structure of the metal outer wall structure will be exemplarily described below in combination with various embodiments.

[0176] First, in combination with Figure 1 The use environment of the metal outer wall structure is described as follows. As shown in Figure 1 , the metal outer wall structure includes an outer wall fixing node 10, a metal plate 20, and a wall body 30. The wall body 30 is the inner wall structure of a building, the metal plate 20 is fixedly connected with the wall body 30 through the outer wall fixing node 10, and multiple metal plates 20 are arranged side by side to cover the wall body 30. The outer wall fixing node 10 includes a connecting structure 100 and a connecting plate 200. The connecting structure 100 is used to be fixedly connected with the metal plate 20, and the connecting plate 200 is used to be fixedly connected with the wall body 30. Meanwhile, the connecting structure 100 and the connecting plate 200 are fixedly connected to fix the metal plate 20 and the wall body 30. The structure and function of the connecting structure 100 and the connecting plate 200 in the outer wall fixing node 10 will be exemplarily described below in combination with various embodiments.

[0177] In some embodiments, as shown in Figure 2 , the connecting structure 100 includes a fitting wall 110 and an extension wall 120. The outer surface of one side of the fitting wall 110 forms a fitting surface 111. The fitting surface is used to be fitted with the metal plate 20 to realize the fixed connection with the metal plate 20. It should be noted that the fitting surface 111 can be directly fixedly connected with the metal plate 20 in Figure 1 through structural glue. The fitting surface 111 can also form a groove to accommodate structural glue and be fitted with the metal plate 20 to be fixedly connected with the metal plate 20.

[0178] The extension wall 120 extends from the surface of the fitting wall 110 opposite to the fitting surface 111. The extension wall 120 extends along a first direction (the first direction is shown in Figure 2The extending wall 120 extends in a first direction (indicated by the arrow direction) and the first direction is not parallel to the abutting surface 111, so that the extending wall 120 can extend towards a direction away from the abutting wall 110, wherein the extending wall 120 surrounds a slot 121, and the opening direction of the slot 121 is not parallel to the abutting surface 111, and the slot 121 is used to accommodate the fixing edge 22 of the metal plate 20. It can be understood that the metal plate 20 comprises a plate body 21 and the fixing edge 22, and the fixing edge 22 is formed by protruding along the thickness direction of the plate body 21. By inserting the fixing edge 22 into the slot 121, the metal plate 20 can be abutted to the abutting wall 110 through the abutting surface 111, and at the same time, the metal plate 20 is inserted to the extending wall 120 through the slot 121, that is, not only the tangential force between the metal plate 20 and the connecting structure 100 is borne by the adhesive force between the abutting surface 111 and the metal plate 20, but also the bending moment exerted by the metal plate 20 on the connecting structure 100 is borne by the action force between the fixing edge 22 and the slot 121, so that the fixation of the metal plate 20 and the connecting structure 100 is more reliable, and the risk of the metal plate 20 falling off is reduced. Moreover, in the case that the thickness of the metal plate 20 is relatively small, the metal plate 20 may be bent under the action of external force or assembly force. By inserting the edge of the metal plate 20 into the slot 121, the bending deformation of the metal plate 20 can be limited by the action force exerted on the metal plate 20 by the slot 121.

[0179] The utility model embodiment provides a kind of connecting structure, which is applied to metal outer wall structure, and the metal outer wall structure includes metal plate, and the metal plate includes plate body and fixed edge, and the fixed edge protrudes along the thickness direction of plate body, and the connecting structure includes: it has the abutting surface for abutting with metal plate, and the extending wall that surrounds the slot is formed, and the extending wall is protruded by the surface of abutting wall opposite to abutting surface, and the opening direction of slot is not parallel to abutting surface, wherein, slot is used to accommodate the fixed edge of metal plate, it can be understood that, the shear force between metal plate and connecting structure is borne by the abutting of abutting surface and metal plate, and the bending moment between metal plate and connecting structure is borne by the support force between slot and fixed edge, so as to improve the fixation reliability between connecting structure and metal plate, and reduce the risk of metal plate falling off.

[0180] In some embodiments, as shown in Figure 2 The opening direction of the slot 121 is parallel to the first direction, and in the assembled state of the slot 121 and the metal plate 20, the opening of the slot 121 is parallel to the horizontal direction, so that the support force exerted on the fixed edge 22 by the inner wall of the slot 121 is parallel to the vertical direction, so that the support force can more effectively resist the gravity of the metal plate 20, thereby further improving the fixation reliability of the connecting structure 100 and the metal plate 20, and further reducing the risk of the metal plate 20 falling off.

[0181] In some embodiments, as shown in Figure 3As shown, the slot 121 comprises a plurality of accommodating portions 122, that is, the plurality of accommodating portions 122 are not directly formed as an integral structure, but are respectively formed as a plurality of spaced accommodating portions 122, each of which can be formed separately, thereby reducing the manufacturing difficulty and cost of the slot 121, and further improving the fixing reliability by forming a plug-in structure between the plurality of fixing edges 22 and the plurality of accommodating portions 122.

[0182] In some embodiments, as shown in Figure 4 As shown, the connecting structure 100 further comprises a branch wall 130, the branch wall 130 extends the wall 120 to form a first cavity 141, the opening of the first cavity 141 is not parallel to the first direction (the first direction is shown by the arrow direction in Figure 4 In the process of assembling the metal plate 20, the structure of the connecting plate 200 in Figure 1 It can be understood that, in the state that the connecting structure 100 is fixedly connected with the metal plate 20 and the connecting plate 200, the opening of the first cavity 141 faces the vertical direction, and the gravity of the metal plate 20 applied to the connecting structure 100 can be transmitted to the connecting plate 200 through the force of the side wall of the first cavity 141 and the connecting plate 200, so as to convert part of the bending moment borne by the connecting plate 200 into tensile stress. Specifically, the gravity of the metal plate 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 the gravity, and one side of the connecting plate 200 is in tension and the other side is in compression under the action of the bending moment. The tensile capacity of the ductile material is greater than the compressive capacity, and by arranging the first cavity 141, part of the bending moment transmitted to the connecting plate 200 by the connecting structure 100 can be converted into tensile stress. At this time, the stress on the compression side of the connecting plate 200 can be offset by the tensile stress, and the stress on the tension side of the connecting plate 200 is superimposed with the tensile stress, that is, the tensile action of the connecting plate 200 is enhanced and the tensile action is weakened. Since the connecting plate 200 is generally made of ductile material such as metal, the stress state of the connecting plate 200 is optimized by the tensile stress, thereby better utilizing the tensile capacity of the connecting plate 200, so that the metal plate 20 can be more reliably fixedly connected with the wall 30, that is, the reliability of the fixed node is improved.

[0183] In some embodiments, as shown in Figure 5 As shown, the wall 120 surrounds to form a second cavity 142, and it can be understood that the wall 120 surrounds to form the second cavity 142 by bending or by forming a branch structure, and the second cavity 142 is arranged along the first direction (the first direction is shown by the arrow in Figure 5 It should be noted that, Figure 1The size of the connecting plate 200 in the connecting structure 100 for extending into the first cavity 141 is generally small, in order to enable the first cavity 141 to form no large gap with the part, the first cavity 141 generally does not occupy the entire size space of the extension wall 120 in the first direction, by arranging 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 of the extension wall 120 and the connecting plate 200, so that the connecting structure 100 and the connecting plate 200 are more fully contacted, and then the gravity of the metal plate 20 is more fully transmitted to the connecting plate 200, further enhancing the load bearing capacity of the connecting plate 200, thereby further improving the reliability of the outer wall fixing node 10; wherein, according to the different structures of the second cavity 142, the second cavity 142 can also realize different functions, for example, the second cavity 142 is arranged as a closed cavity, while the wall surface of the closed cavity and the connecting plate 200 are more fully attached, 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 any order, optionally, the first cavity 141 is closer to the attached wall 110 than the second cavity 142, optionally, the second cavity 142 is closer to the attached wall 110 than the first cavity 141; at the same time, the first cavity 141 and the second cavity 142 can be arranged at intervals, and the first cavity 141 and the second cavity 142 can be arranged side by side and share the same wall surface.

[0184] In some embodiments, as shown in Figure 6 , the first cavity 141 and the second cavity 142 are arranged in sequence along the first direction (the first direction is shown by the arrow direction in Figure 6 ), that is, the second cavity 142 is closer to the attached surface 111 than the first cavity 141, and the fixed edge 22 is fixedly connected with the part of the extension wall 120 surrounding the second cavity 142. It can be understood that the second cavity 142 not only realizes the heat insulation function of the connecting structure, but also provides sufficient mounting space for the fixed edge 22 and the connecting structure 100. Specifically, in the assembled state of the connecting plate 200 and the connecting structure 100 in Figure 1 , the first cavity 141 needs to accommodate the fixed plate 120, so that the first cavity 141 cannot provide mounting space for the fixed edge 22, and the second cavity 142 has no requirement for accommodating other hard structures, and the part of the extension wall 120 surrounding the second cavity 142 provides mounting space for the fixed edge 22, and there is no problem of assembly interference between other hard structures and the fixed edge 22. By making the second cavity 142 closer to the attached surface 111, the second cavity 142 can be closer to the metal plate 20 in the assembled state of the metal plate 20 and the connecting structure 100, thereby facilitating the fixed connection between the fixed edge 22 and the extension wall 120.

[0185] It should be noted that the fixed edge 22 can be fixedly connected with the extension wall 120 in any manner. For example, the fixed edge 22 is fixedly connected with the portion of the extension wall 120 surrounding the second cavity 142 through a clamping structure. For example, the fixed edge 22 is fixedly connected with the portion of the extension wall 120 surrounding the second cavity through adhesion.

[0186] In some embodiments, as shown in Figure 7 the fixed edge 22 is fixedly connected with the portion of the extension wall 120 surrounding the second cavity 142 through the connecting member 800, and the connecting member 800 extends into the second cavity 142. It can be understood that, by fixing the fixed edge 22 with the portion of the extension wall 120 surrounding the second cavity 142 through the connecting member 800, not only the outer surface of the extension wall 120 can be fixedly connected with the fixed edge 22, but also the inner space of the second cavity 142 can be used to provide a fixing space for the fixed edge 22, so that the structure of the extension wall 120 can be more fully utilized to provide a larger mounting space for the fixed edge 22, thereby further improving the fixing reliability of the fixed edge 22 and further reducing the risk of the metal plate 20 falling off. The connecting member 800 can be a fixing screw or a rivet.

[0187] In some embodiments, as shown in Figure 8 the extension wall 120 and the abutting wall 110 surround the second cavity 142, that is, one side of the abutting wall 110 is used to form the abutting surface 111, and the other side of the abutting wall 110 is also used to surround the second cavity 142, so that the second cavity 142 can be closer to the abutting surface 111, and in the assembled state of the metal plate 20 and the connecting structure 100, the fixed edge 22 can be more conveniently fixedly connected with the portion of the extension wall 120 surrounding the second cavity 142.

[0188] In some embodiments, as shown in Figure 9 the fixed edge 22 is fixedly connected with the portion of the extension wall 120 surrounding the second cavity 142, that is, the fixed edge 22 is not completely accommodated in the insertion slot 121, that is, the fixed edge 22 extends out of the end of the plate body 21 to form an insertion end, and only the insertion end is located in the insertion slot 121 and the remaining part of the fixed edge 22 is located outside the insertion slot 121. In this state, the portion of the extension wall 120 surrounding the second cavity 142 is in abutment with the portion of the fixed edge 22 located outside the insertion slot 121, so that the abutting force between the extension wall 120 and the fixed edge 22 can further resist the bending moment applied by the metal plate 20 to the connecting structure 100, thereby further improving the fixing reliability between the connecting structure 100 and the metal plate 20 and further reducing the risk of the metal plate 20 falling off.

[0189] In some embodiments, such as Figure 10 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 metal plate 20 and the connecting structure 100 and further reducing the risk of the metal plate 20 falling off.

[0190] In some embodiments, such as Figure 11 As shown, the second cavity 142 is filled with a filler material. Depending on the filler material, the second cavity 142 can have different functions. The filler material includes a fixing adhesive, and... Figure 7 With the connector 800 inserted into the second cavity 142, the filling material can bond with the part of the connector 800 that extends into the second cavity 142, thereby further improving the fixing reliability of the fixed edge 22 and the connecting structure 100 and further reducing the risk of the metal plate 20 falling off.

[0191] 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 7 The connector 800 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 metal plate 20 falling off.

[0192] In some embodiments, such as Figure 12 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 12 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 12 (as shown by the solid arrow) perpendicular to and in line with the second direction (as shown by the solid arrow) Figure 12 As indicated 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 cavity 141 and... Figure 2 The cross-sectional shape of the slot 121, along with the fitting wall 110, the extension wall 120, and the branch wall 130 extending in a third direction to form a plate-like or strip-like structure, forms a structure capable of interacting with... Figure 1The connecting plate 200 in the connecting structure 100 is more reliable in connecting the first cavity 141, and meanwhile, the fixing area with the connecting plate 200 and the metal plate 20 is increased in the third direction, further improving the connection reliability of the connecting structure 100 with the metal plate 20 and the connecting plate 200.

[0193] In some embodiments, as shown in Figure 13 the first cavity 141 extends from one end of the extending wall 120 to the other end of the extending wall 120 in the third direction (the third direction is indicated by the arrow in Figure 13 It can be understood that the connecting structure 100 has the first cavity 141 in each cross section perpendicular to the third direction, and the connecting structure 100 can be formed by one-piece molding. Alternatively, the part of the connecting structure 100 forming the first cavity 141 is made of a metal profile, and the first cavity 141 can facilitate the metal profile to be formed by one-piece molding to have the first cavity 141. Figure 14 Figure 14 In some embodiments, as shown in Figure 1 the size of the first cavity 141 is smaller than the size of the extending wall 120 in the third direction (the third direction is indicated by the arrow in It can be understood that in each cross section of the connecting structure 100 perpendicular to the third direction, a part of the cross section has the first cavity 141, and the other part of the cross section does not have the first cavity 141. The part of the connecting structure 100 that needs to cooperate with the connecting plate 200 is provided with the first cavity 141, and the other part of the connecting structure 100 is provided with a structure without the first cavity 141, so as to improve the overall structural strength of the connecting structure 100 while improving the assembly reliability of the connecting structure 100 with the connecting plate 200. It should be noted that the non-through first cavity 141 can also be formed on the basis of one-piece molding. For example, an entity structure with a target shape but without the first cavity inside is formed by one-piece molding, and then the first cavity 141 is machined by cutting processing, such as milling processing.

[0194] Figure 15 In some embodiments, as shown in Figure 1 ​One side of the metal plate 20 forms an overall structure of the metal plate frame. Simultaneously, the connecting frame 50 is fixedly connected to multiple connecting plates 200. This can be understood as the metal plate frame structure connecting the connecting plates 200 in multiple external wall fixing nodes 10 into a whole. Local forces on the metal plate 20 can be transferred to multiple external wall fixing nodes 10 through the connecting frame 50, thereby increasing the structural strength of the external wall structure by having multiple external wall fixing nodes 10 jointly bear the external force. 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... Figure 16 to Figure 21 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. Figure 16 to Figure 21 Other methods are shown.

[0195] like Figure 16 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.

[0196] Optional, such as Figure 16 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 16 (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 metal plate 20. Placing the corner bracket 51 away from the end of the metal plate 20 can reduce the risk of motion interference between the corner bracket 51 and the metal plate 20.

[0197] Optional, such as Figure 17As shown, the positioning end of the connecting structure 100 has a positioning structure 191. The positioning structure 191 is used to abut against the corner bracket 51 to position the corner bracket 51 to the target position. It can be understood that the abutting force applied to the corner bracket 51 by the positioning structure 191 keeps the corner bracket 51 in the target position. Thus, during the assembly process, there is no need to use an additional positioning device or the assembly personnel's hands to position the corner bracket 51, which facilitates fixing the corner bracket 51 to the target position. The target position is the position where the mounting hole of the corner bracket 51 and the connecting hole of the connecting structure 100 are aligned. Moreover, by setting the positioning structure 191, it is also beneficial to the automatic assembly of the connecting frame 50. That is, during the automated assembly process, after the corner bracket 51 is moved to the vicinity of the target position by the moving device, the corner bracket 51 can be positioned to the target position by abutting against the positioning structure 191, and the corner bracket 51 can still be kept in the target position after the moving device releases the corner bracket 51. It should be noted that the positioning structure 191 can be any structure capable of holding the corner bracket 51 in the target position by resisting force. For example, the positioning structure 191 can be a positioning groove or a positioning protrusion, or one part can be a positioning groove and the other part can be a positioning protrusion. The following will be combined with Figure 17 to Figure 20 The structure of positioning structure 191 is illustrated by way of example.

[0198] like Figure 17 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 17 As indicated by the middle arrow, the positioning cavity 192 is recessed and used to accommodate at least a portion of the corner bracket 51. This can be understood as the positioning cavity 192 having an opening facing a first direction. Inserting the corner bracket 51 into the positioning cavity 192 through this opening along the first direction allows the corner bracket 51 to abut against the inner wall of the positioning cavity 192, thereby positioning the corner bracket 51 at the target position. Optionally, the positioning ends of adjacent connecting structures 100 in the connecting frame 50 each form a positioning cavity 192. The positioning cavities 192 of the two connecting structures 100 are connected and form the same shape as the corner bracket 51 perpendicular to the thickness direction, thus allowing the positioning cavities 192 of the two splicing structures 100 to be spliced ​​together to form a cavity for accommodating the corner bracket 51.

[0199] like Figure 18 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 18The positioning protrusion 193 is arranged on the positioning end, and the positioning protrusion 193 is in abutment with the corner code 51 in the direction perpendicular to the first direction. It can be understood that the corner code 51 is in abutment with the positioning end to limit the movement of the corner code 51 relative to the connecting structure 100 in the first direction, and the movement of the corner code 51 relative to the connecting structure 100 in the direction perpendicular to the first direction is limited by the positioning protrusion 193, so that the corner code 51 can be positioned at the target position. It should be noted that the corner code 51 can approach the positioning protrusion 193 from different directions. For example, the corner code 51 approaches the positioning protrusion 193 in the first direction and is in abutment with the positioning protrusion 193 in the direction perpendicular to the first direction. For example, the corner code 51 approaches the positioning protrusion 193 in the direction perpendicular to the first direction after approaching the positioning end and is in abutment with the positioning protrusion 193.

[0200] Optionally, as shown in Figure 19 The first connection part 511 and the second connection part 512 are connected with two adjacent connecting structures 100 in the connecting frame 50 respectively, so that the connecting structures 100 can be spliced to form the connecting frame 50. Meanwhile, the positioning protrusions 193 of the two adjacent connecting structures 100 in the connecting frame 50 are in abutment with the first connection part 511 and the second connection part 512 respectively, and the extension directions of the two positioning protrusions 193 form a first included angle. It can be understood that the two positioning protrusions 193 of the two adjacent connecting structures 100 form a protrusion structure with the same shape as the corner code 51 in the direction perpendicular to the thickness direction. The two positioning protrusions 193 can be in abutment with the two connection parts of the corner code 51 in two orthogonal directions (for example, the second direction and the third direction) perpendicular to the first direction respectively, so as to limit the movement of the corner code 51 relative to the connecting structure 100 in the above two orthogonal directions respectively. That is, by simplifying the structure of the positioning protrusion 193 of the single connecting structure 100, the manufacturing cost of the connecting structure 100 is reduced.

[0201] Optionally, as shown in Figure 20 The connecting structure 100 has a plurality of positioning protrusions 193. The positioning protrusions 193 are arranged at intervals in the second direction (the second direction is indicated by the dotted arrow in Figure 20 The positioning space is surrounded by the adjacent positioning protrusions 193, and the inner wall of the positioning space is used to abut with the corner code 51. It can be understood that the positioning space has a first direction (the first direction is indicated by the solid arrow in Figure 20The 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.

[0202] Optional, such as Figure 20 As shown, in the first direction (the first direction is as follows) Figure 20 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 20 (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.

[0203] 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.

[0204] like Figure 21As shown, the adjacent connecting structures 100 in the connecting frame 50 are fixedly connected by the corner joint 52. It can be understood that the corner joint 52 is a block structure, which includes two parts, and the extension directions of the two parts form a certain included angle, which can be, for example, a right angle. The two parts of the corner joint 52 are inserted into the insertion slots of the connecting structures 100, respectively, and then the corner joint 52 and the connecting structures 100 are fixedly connected by screws, so as to splice the plurality of connecting structures 100 to form the connecting frame 50. It should be noted that the insertion slot for inserting the corner joint 52 can be an additional insertion slot structure, or the insertion slot can be formed by using the first cavity 141. Alternatively, the adjacent connecting structures 100 can also be spliced to form the connecting frame 50 by the corner joint 52 and the corner brace 51. For example, the adjacent connecting structures 100 are connected by the corner joint 52 at the end portion having the first cavity 141, and the adjacent connecting structures 100 are fixedly connected by the corner brace 51 at the end portion not having the first cavity 141. It should be noted that the corner joint 52 can be assembled with the connecting structure 100 in different ways. For example, the corner joint 52 can be fixedly connected with the connecting structure 100 by a connecting pin. Specifically, the corner joint 52 and the insertion slot of the connecting structure 100 form a clearance fit or an interference fit, a pin hole is provided in the connecting structure 100, and then the corner joint 52 and the connecting structure 100 are fixedly connected by filling a glue between the corner joint 52 and the insertion slot and by using a pin. Alternatively, the corner joint 52 can also be fixedly connected with the connecting structure 100 by extrusion. Specifically, the corner joint 52 and the insertion slot of the connecting structure 100 form an interference fit, the corner joint 52 is simultaneously extruded into the insertion slots of the two adjacent connecting structures 100, and the connecting structure 100 does not need to be provided with a pin hole. The splicing mode of the corner joint 52 and the connecting structure 100 will be described below in conjunction with the embodiments.

[0205] In some embodiments, as Figure 22 shown, the extension wall 120 also surrounds the first insertion cavity 181 and the second insertion cavity 182, which are arranged at intervals along the first direction (the first direction is indicated by the arrow in Figure 22 Fig. 6). The first insertion cavity 181 and the second insertion cavity 182 are both used to accommodate a part of the corner joint 52 in Figure 21 Fig. 5, that is, two corner joints are respectively inserted into the first insertion cavity 181 and the second insertion cavity 182 of the two connecting structures 100, so that the two connecting structures 100 are connected by the corner joint 52 at both ends in the first direction. As Figure 23 shown in Fig. 6, the first insertion cavity 181 has a second opening, and the second insertion cavity 182 has a third opening in the third direction (the third direction is indicated by the arrow in Figure 23As shown in FIG. 12, in the state that the corner piece 52 is inserted into the two connection structures 100, the corner piece 52 is completely accommodated in the two connection structures 100. Exemplarily, the extension directions of the two connection structures 100 form an included angle of 90 degrees. In the extension direction of the connection structure 100, the edges of the two connection structures 100 form inclined surfaces, which form an included angle of 45 degrees with the third direction. When the two connection structures 100 are spliced by the corner piece 52, the two inclined surfaces can be attached and the extension directions of the two connection structures 100 form an included angle of 90 degrees, and the corner piece 52 can be completely accommodated in the two connection structures 100.

[0206] As shown in FIG. 13, in the state that the corner piece 52 is inserted into the two connection structures 100, the corner piece 52 is partially accommodated in the two connection structures 100, and the other part of the corner piece 52 is located outside the connection structure 100. Exemplarily, in the extension direction of the connection structure 100, the edges of the two connection structures 100 are perpendicular to each other. When the two connection structures 100 are spliced by the corner piece 52, a certain space is formed between the two edges, and a part of the corner piece 52 is located in the space and is not accommodated in the connection structure 100. Figure 24 As shown in FIG. 13, in the state that the corner piece 52 is inserted into the two connection structures 100, the corner piece 52 is partially accommodated in the two connection structures 100, and the other part of the corner piece 52 is located outside the connection structure 100. Exemplarily, in the extension direction of the connection structure 100, the edges of the two connection structures 100 are perpendicular to each other. When the two connection structures 100 are spliced by the corner piece 52, a certain space is formed between the two edges, and a part of the corner piece 52 is located in the space and is not accommodated in the connection structure 100.

[0207] Figure 25 As shown in FIG. 13, in the state that the corner piece 52 is inserted into the two connection structures 100, the corner piece 52 is partially accommodated in the two connection structures 100, and the other part of the corner piece 52 is located outside the connection structure 100. Exemplarily, in the extension direction of the connection structure 100, the edges of the two connection structures 100 are perpendicular to each other. When the two connection structures 100 are spliced by the corner piece 52, a certain space is formed between the two edges, and a part of the corner piece 52 is located in the space and is not accommodated in the connection structure 100.

[0208] As shown in FIG. 14, in the state that the corner piece 52 is inserted into the two connection structures 100, the corner piece 52 is partially accommodated in the two connection structures 100, and the other part of the corner piece 52 is located outside the connection structure 100. Exemplarily, in the extension direction of the connection structure 100, the edges of the two connection structures 100 are perpendicular to each other. When the two connection structures 100 are spliced by the corner piece 52, a certain space is formed between the two edges, and a part of the corner piece 52 is located in the space and is not accommodated in the connection structure 100. Figure 23 Figure 23 As shown in FIG. 14, in the state that the corner piece 52 is inserted into the two connection structures 100, the corner piece 52 is partially accommodated in the two connection structures 100, and the other part of the corner piece 52 is located outside the connection structure 100. Exemplarily, in the extension direction of the connection structure 100, the edges of the two connection structures 100 are perpendicular to each other. When the two connection structures 100 are spliced by the corner piece 52, a certain space is formed between the two edges, and a part of the corner piece 52 is located in the space and is not accommodated in the connection structure 100.

[0209] ​​Optionally, the first plug-in cavity 181 has two, and in the third direction, and in two directions, the two first plug-in cavities 181 are located at both ends of the extension wall 120, which can be understood as that the two first plug-in cavities 181 are arranged in the third direction, and the length of the first plug-in cavity 181 in the third direction is less than the length of the connecting structure 100, so that the connecting structure 100 can be connected to the group corner 52 in the third direction through the first plug-in cavity 181. Figure 21 Optionally, the first plug-in cavity 181 has two, and in the third direction, and in two directions, the two first plug-in cavities 181 are located at both ends of the extension wall 120, which can be understood as that the two first plug-in cavities 181 are arranged in the third direction, and the length of the first plug-in cavity 181 in the third direction is less than the length of the connecting structure 100, so that the connecting structure 100 can be connected to the group corner 52 in the third direction through the first plug-in cavity 181.

[0210] Optionally, the second plug-in cavity 182 has two, and in the third direction, and in two directions, the two second plug-in cavities 182 are located at both ends of the extension wall 120, which can be understood as that the two second plug-in cavities 182 are arranged in the third direction, and the length of the second plug-in cavity 182 in the third direction is less than the length of the connecting structure 100, so that the connecting structure 100 can be connected to the group corner 52 in the third direction through the second plug-in cavity 182. Figure 21 Optionally, the second plug-in cavity 182 has two, and in the third direction, and in two directions, the two second plug-in cavities 182 are located at both ends of the extension wall 120, which can be understood as that the two second plug-in cavities 182 are arranged in the third direction, and the length of the second plug-in cavity 182 in the third direction is less than the length of the connecting structure 100, so that the connecting structure 100 can be connected to the group corner 52 in the third direction through the second plug-in cavity 182.

[0211] In some embodiments, as shown in Figure 26 The connecting structure 100 further comprises a support wall 183, which is fixed to the end of the branch wall 130 in the second direction (the second direction is indicated by the solid arrow in Figure 26 The connecting structure 100 further comprises a support wall 183, which is fixed to the end of the branch wall 130 in the second direction (the second direction is indicated by the solid arrow in Figure 26As 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 26 and Figure 27 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.

[0212] In some embodiments, such as Figure 28As shown, the extension wall 120 also encloses to form a third cavity 143. It can be understood that the extension wall 120 encloses to form the third cavity 143 by bending or by forming a branch structure. According to different structures of the third cavity 143, the third cavity 143 can also realize different functions. For example, the third cavity 143 is arranged as a closed cavity, the first plug-in cavity 181 can be formed by using the third cavity 143, and the heat insulation capacity of the connecting structure 100 can be improved by filling the third cavity 143 with heat insulation material.

[0213] In some embodiments, as shown in Figure 29 As shown, the third cavity 143 and the first cavity 141 are arranged along a second direction (the second direction is shown by the arrow direction in Figure 29 In this arrangement, the third cavity 143 can form a first plug-in slot, and the third cavity 143 can also realize the lightweight of the connecting structure 100.

[0214] In some embodiments, as shown in Figure 28 As shown, the connecting structure 100 forms an integrated structure, and the material of the connecting structure 100 is metal, that is, the weight of the metal plate 20 in Figure 1 is directly borne by the integrated metal structure, and the weight of the metal plate 20 is more reliably transmitted to the connecting plate 200, further improving the reliability of the outer wall fixing node 10; optionally, the extension wall 120 also encloses to form a third cavity 133, so that the extension wall 120 can be more reliably attached to the connecting plate 200.

[0215] In some embodiments, the connecting structure 100 is a split structure, for example, as shown in Figure 30 As shown, the connecting structure 100 includes a first part 151 and a second part 152. The first part 151 includes the part of the attachment wall 110 and the extension wall 120 for enclosing to form the first cavity 141, the second cavity 142, and the plug-in slot 121. The first part 151 is used for fixedly connecting with the metal plate 20 in Figure 1 . Specifically, the attachment surface 111 is fixedly connected with the metal plate 20 by adhesion, the plug-in slot 121 and the second cavity 142 are fixedly connected with the fixed edge 22 of the metal plate 20, and the first cavity 141 is used for accommodating the fixed branch plate 120 to be fixedly connected with the connecting plate 200, that is, for fixedly connecting with the metal plate 20 and for fixedly connecting with Figure 1The portion of the connecting plate 200 that is fixedly connected forms an integral first part 151. The weight of the metal plate 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] In some embodiments, such as Figure 31 As shown, the second part 152 surrounds and forms the fourth cavity 144. By providing the fourth cavity 144, the second part 152 can also perform different functions. For example, by filling the fourth cavity 144 with adhesive, the second part 152 can also interact with... Figure 1 The connecting body 210 is connected more reliably. Optionally, the fourth cavity 144 is a closed cavity. By making the fourth cavity 144 a closed cavity, the second part 152 can be more reliably connected to... Figure 1 The connecting body 210 abuts against the second part 152 so that the force exerted by the metal plate 20 on the connecting structure 100 can also be transmitted to the connecting body 210, which further improves the fixing reliability of the metal plate 20 and further reduces the risk of the metal plate 20 falling off; optionally, the fourth cavity 144 is filled with heat insulation material, thereby improving the heat insulation capacity of the second part 152.

[0217] In some embodiments, such as Figure 32 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 32 (As indicated by the middle arrow), that is, in the state of being assembled with the metal plate 20, the opening of the fitting cavity 112 faces... Figure 1The bonding cavity 112 is used to accommodate structural glue, the bonding surface 111 is bonded with the metal plate 20 through the structural glue, the bonding cavity 112 is arranged to enable the bonding surface 111 to accommodate more structural glue and gather the structural glue in the space where the bonding surface 111 contacts the metal plate 20, which can enable more structural glue to participate in the fixed connection of the bonding surface 111 and the metal plate 20, and can also limit the structural glue from being squeezed out of the contact space of the bonding surface 111 and the metal plate 20, so that the bonding surface 111 can be more reliably bonded with the metal plate 20, further improving the reliability of the outer wall fixed 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 being concave in the bonding surface 111, and for example, the bonding cavity 112 can also be formed by surrounding the protruding structure protruding from the bonding surface 111.

[0218] In some embodiments, as shown in Figure 33 The connecting structure 100 further includes a separation protrusion 170, the separation protrusion 170 protrudes from the bonding surface 111 in the first direction (the first direction is indicated by the arrow direction in Figure 33 , wherein a plurality of separation protrusions 170 are arranged at intervals, and adjacent separation protrusions 170 and the bonding surface 111 surround the bonding cavity 112, that is, the bonding cavity 112 is formed by surrounding the protruding structure protruding from the bonding surface 111, so that the bonding cavity 112 can be formed without weakening the structural strength of the bonding wall 110.

[0219] In some embodiments, as shown in Figure 33 At least two separation protrusions 170 form a support protrusion 171, the support protrusion 171 is used to abut the metal plate 20, and the support protrusion 171 protrudes from the bonding surface 111 by the same size, which can be understood as the support protrusion 171 protrudes from the bonding surface 111 by the same height, and two spaced support protrusions 171 can determine a positioning plane parallel to the bonding surface 111, and the long and wide surface of the metal plate 20 is parallel to the bonding surface 111 in the state that each support protrusion 171 is bonded with the metal plate 20, that is, in the process of assembly, the automatic leveling of the metal plate 20 can be realized by arranging a plurality of support protrusions 171.

[0220] In some embodiments, as shown in Figure 34As shown, the abutment surface 111 includes a corner edge 114, which is an edge of the abutment surface 111 close to the slot 121. The separation protrusion 170 is spaced apart from the corner edge 114. It can be understood that, in the state of assembling the connecting structure 100 and the metal plate 20, the fixing edge 22 needs to bypass the abutment surface 111 from the corner edge 114 to be inserted with the slot 121. If the distance between the separation protrusion 170 and the corner edge 114 is too close, the fixing edge 22 may interfere with the separation protrusion 170 at the corner edge 114. Spacing the separation protrusion 170 closest to the corner edge 114 in each separation protrusion 170 from the corner edge 114 by a certain distance can reduce the possibility of interference between the fixing edge 22 and the separation protrusion 170.

[0221] In some embodiments, as shown in Figure 34 In the second direction (the second direction is indicated by an arrow in Figure 35 the drawing), the abutment wall 110 extends away from the branch wall 130, and the at least two separation protrusions 170 are respectively located on the two sides of the extension wall 120. By extending the abutment wall 110 away from the extension wall 120, the abutment surface 111 can have a larger area in the second direction and can provide a larger space for the separation protrusion 170. At the same time, the at least two separation protrusions 170 are respectively arranged on the two sides of the extension wall 120 in the second direction, so that the abutment cavity 112 can span the extension wall 120 in the second direction. The abutment cavity 112 arranged in this way not only has a larger bonding area, but also can offset the bending moment borne by the abutment surface 111 on the two sides of the extension wall 120 to a certain extent, thereby reducing the torque transmitted to the extension wall 120, and further improving the fixing reliability of the metal plate 20 and the abutment surface 111 in Figure 1 .

[0222] In some embodiments, as shown in Figure 35 In the second direction (the second direction is indicated by an arrow in Figure 35 the drawing), the at least one separation protrusion 170 is flush with the extension wall 120. By making the separation protrusion flush with the extension wall 120, the separation protrusion 170 can be formed at the same time as the extension wall 120 is formed, thereby reducing the manufacturing cost and manufacturing difficulty of the connecting structure 100.

[0223] The metal outer wall structure is applied to a building, and the structure and function of the metal outer wall structure are exemplarily described in combination with the embodiments.

[0224] In some embodiments, as shown in Figure 1As shown, the metal outer wall structure comprises: an outer wall fixed node 10, a metal plate 20 and a wall body 30. The metal plate 20 is attached to the attachment surface 111, and the wall body 30 is fixedly connected to the second end of the connecting body 210. It can be understood that the metal plate 20 is fixedly connected to the connecting structure 100, the connecting plate 200 is fixedly connected to the connecting structure 100, and the wall body 30 is fixedly connected to the connecting plate 200, so that the metal plate 20 is fixedly connected to the wall body 30.

[0225] The outer wall fixed node 10 comprises: a connecting plate 200 and a connecting structure 100 shown in any one of the drawings in the specification Figure 35 The connecting structure 100 is fixedly connected to the connecting plate 200, and the connecting structure 100 is also fixedly connected to the metal plate 20, so as to fixedly connect the metal plate 20 to the wall body 30. The fixed manner of the metal plate 20 and the connecting structure 100 will be described in detail below, as shown in Figure 2 The metal plate 20 comprises a plate body 21 and a fixed edge 22, the fixed edge 22 extends along the thickness direction of the plate body 21, the plate body 21 is bonded to the attachment surface 111, and at the same time, the connecting structure 100 has a slot 121 and at least part of the fixed edge 22 extends into the slot 121, that is, the metal plate 20 is bonded to the connecting structure 100 through the attachment surface 111 and is bonded to the connecting structure 100 through the slot 121, so as to improve the fixed reliability of the metal plate 20 and the connecting structure 100. It should be noted that since the metal plate 20 is made of metal material, compared with other masonry structures, the metal structure has better ductility and better processability, so that the fixed edge 22 can be more conveniently formed on the metal plate 20. For example, by bending, a folded edge can be formed at the edge of the metal plate 20, and the fixed edge 22 can be formed through the folded edge. For example, by welding, the fixed edge 22 can be formed on the outer surface of the plate body 21, so as to further increase the fixed reliability of the metal plate 20 and the connecting structure 100 through the fixed edge 22, and reduce the risk of the metal plate 20 falling off.

[0226] The connecting plate 200 can be fixedly connected to the connecting structure 100 in any manner. For example, the connecting plate 200 is directly fixedly connected to the connecting structure 100 through a screw. For example, as shown in Figure 36 The connecting plate 200 comprises a connecting body 210 and a fixed support plate 220. The connecting body 210 extends along a third direction (the third direction is shown by the arrow in Figure 36 The fixed support plate 220 extends from the outer surface of the connecting body 210, and the extending direction of the fixed support plate 220 is not parallel to the third direction, so that the fixed support plate 220 extends away from the connecting body 210. The fixed support plate 220 is used to extend into Figure 4 to Figure 35In the first cavity 141 in any one of the connection structures 100 shown, that is, in the assembled state of the connecting plate 200 and the connection structure 100, the connecting plate 200 is connected with the connection structure 100 through the fixed supporting plate 220, and the bending moment applied by the metal plate 20 to the connecting body 210 is partially converted into tensile stress through the force between the fixed supporting plate 220 and the first cavity 141. The material of the connecting plate 200 is a high-strength ductile material such as metal, which has a higher tensile capacity than a compressive capacity. By providing the fixed supporting plate 220 and extending it into the first cavity 141, the stress condition of the connecting plate 200 can be optimized, the material performance advantage of the connecting plate 200 can be fully utilized, and the load-bearing capacity of the connecting plate 200 is improved, thereby improving the reliability of the external wall fixing node 10. Optionally, as shown in Figure 36 , the fixed supporting plate 220 extends from a position close to the first end of the connecting body 210, that is, in the third direction, the distance between the fixed supporting plate 220 and the first end is less than the distance between the fixed supporting plate 220 and the second end; optionally, as shown in Figure 37 , the fixed supporting plate 220 extends from the first end of the connecting body 210.

[0227] The second end is used to be fixedly connected with the wall body 30 in the connection structure 100, and the second end can be fixed with the wall body 30 in any way. For example, a first hook structure is fixed on the wall body 30, and the second end forms a second hook structure matched with the first hook structure, so that the two hook structures can be hooked to achieve the fixed connection between the second end and the wall body 30. For example, the second end can also be directly fixed with the wall body 30 through an expansion bolt, and has an adhesive structure between the metal plate 20 and the wall body 30. Figure 1

[0228] In some embodiments, as shown in Figure 1 , in the vertical direction, two connection structures 100 are respectively located on both sides of the connecting body 210, and the branch wall 120 and the extension wall 110 of the connection structure 100 surround to form the first cavity 141. At the same time, the fixed supporting plate 220 extends from both sides of the connecting body 210 and respectively extends into the first cavities 141 of the two connection structures 100, so that the connecting plate 200 is fixedly connected with the two connection structures 100 on both sides of the connecting body 210 through the fixed supporting plate 220. It can be understood that the external wall fixing node 10 is fixedly connected with the wall body 30 through the two connection structures 100. Figure 1 ​In the assembled state of the metal plate 20 in the external wall fixing node 10, two connecting structures of the external wall fixing node 10 are fixedly connected with two adjacent metal plates 20 respectively, and the connecting plate 200 is fixedly connected with the two connecting structures 100 simultaneously to fix the two adjacent metal plates 20 and the wall body 30, and meanwhile, there is fixed glue between the two metal plates 20 to further improve the fixing reliability of the metal plate 20 and reduce the risk of falling of the metal plate 20. Optionally, there is thermal insulation material between the adjacent metal plates 20, which can block the gap of the metal plate 20 to improve the heat insulation capacity of the metal external wall structure.

[0229] In some embodiments, as shown in Figure 38 , the first cavity 141 has filling material, which is used to fill the gap between the inner wall of the first cavity 141 and the fixed supporting plate 220, so that the inner wall of the first cavity 141 can more reliably transmit the gravity of the metal plate 20 to the fixed supporting plate 220. Optionally, the filling material is slurry, glue or a mixture of slurry and glue. In the case that the filling material includes glue, the filling material not only fills the gap between the inner wall of the first cavity 141 and the fixed supporting plate 220, but also bonds the inner wall of the first cavity 141 and the fixed supporting plate 220, so that the inner wall of the first cavity 141 and the fixed supporting plate 220 are more reliably fixed, thereby further improving the reliability of the external wall fixing node 10.

[0230] In some embodiments, as shown in Figure 39 , the fixed supporting plate 220 extends from the end of the connecting body 210 to form a free end, and in the first direction (the first direction is shown by the arrow in Figure 39 , the two sides of the free end form second guide surfaces 221, and the cross-sectional area of the fixed supporting plate 220 decreases in the direction in which the fixed supporting plate 220 extends. The cross section is a plane perpendicular to the direction in which the fixed supporting plate 220 extends. By providing the second guide surfaces 221, when the filling material is injected into the first cavity 141, the second guide surfaces 221 can extrude the filling material to both sides, so that the filling material applies symmetrical extrusion force to the fixed supporting plate 220 from both sides. Through the symmetrical extrusion force, the fixed supporting plate 220 can be located at the middle position of the first cavity 141, and the extrusion force of the filling material on the fixed supporting plate 220 on both sides is balanced, which can not only realize automatic alignment of the fixed supporting plate 220 in the first cavity, but also balance the pressure applied by the filling material on both sides of the fixed supporting plate 220.

[0231] In some embodiments, as shown in Figure 40As shown, the external wall fixing node 10 also includes a gasket 300, which has an insertion groove. The gasket 300 is fitted onto the outside of the fixing support plate 220 through the insertion groove. 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.

[0232] In some embodiments, such as Figure 40 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 46 As 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.

[0233] In some embodiments, such as Figure 41As shown, the insertion groove 320 includes an insertion part 321 and an adhesive part 322, the depth direction of the insertion part 321 is parallel to the extension direction of the fixed support plate 220, and the insertion part 321 is used to accommodate the fixed support plate 220, that is, the fixed support plate 220 can be inserted into the insertion groove 320 along the depth direction of the insertion part 321 so that the gasket 300 can be sleeved outside the fixed support plate 220, and at the same time, the adhesive part 322 is concave from the inner surface of the insertion part 321, and the depth direction of the adhesive part 322 is not parallel to the depth direction of the insertion part 321, so as to form a cavity with a larger volume on the inner surface of the insertion part 321, wherein the adhesive part 322 internally accommodates a filling material, and the filling material includes a fixing glue. It can be understood that the filling material containing the fixing glue 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 also can be filled in the adhesive part 322 to bond the fixed support plate 220 and the insertion groove 320 through the filling material in the adhesive part 322, thereby further improving the fixing reliability of the insertion groove 320 and the fixed support plate 220.

[0234] In some embodiments, as shown in Figure 41 As shown, the insertion part 321 and the fixed support plate 220 form a clearance fit, and the filling material is accommodated between the insertion part 321 and the fixed support plate 220. It can be understood that after the fixed support plate 220 is inserted into the insertion part 321, the filling material is injected into the first cavity 141, at this time, the filling material can enter 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, and the filling material can also enter the insertion groove 320 and between the insertion part 321 and the fixed support plate 220 from the opening of the insertion part 321, thereby bonding the fixed support plate 220 and the insertion groove 320, and at the same time, the clearance fit between the fixed support plate 220 and the insertion part 321 can also enable the position of the fixed support plate 220 to have fine adjustment capability and reduce the risk of assembly interference between the fixed support plate 220 and the insertion part 321.

[0235] In some embodiments, as shown in Figure 42 As shown, the outer surface of the gasket 300 also has a first hollow structure 330, which can accommodate more filling material, so that the gasket 300 and the inner surface of the first cavity 141 can be more reliably bonded.

[0236] In some embodiments, as shown in Figure 42As shown, in the assembled state of the gasket 300 and the connecting structure 100, the first hollow structure 330 is located in the first cavity 141, and it can be understood that, after the gasket 300 is assembled into the first cavity 141 and the first hollow structure 330 is filled with the filling material, the first hollow structure 330 remains inside the first cavity 141, thereby reducing the possibility of the filling material in the first hollow structure 330 leaking out of the first cavity 141, and further improving the bonding reliability of the gasket 300 and the first cavity 141.

[0237] In some embodiments, as shown in Figure 43 , the gasket 300 includes a gasket body 340 and a limiting protrusion 350, the gasket body 340 is partially located in the first cavity 141, and the gasket body 340 has a plug-in slot 320, that is, the gasket body 340 is used for being inserted into the first cavity 141 and can be sleeved outside the fixed support plate 220 through the plug-in slot 320, and 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, so that the insertion depth of the gasket 300 can be adjusted according to the spacing between the adjacent metal plates 20 in Figure 1 , and the position of the gasket 300 can be adapted to the position of the metal plates 20; at the same time, in the extension direction parallel to the fixed support plate 220, the limiting protrusion 350 is located at the end of the gasket body 340, and the limiting protrusion 350 is located outside the first cavity 141, wherein 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, so that the limiting protrusion 350 can abut against the connecting structure 100 to limit the depth of the gasket body 300 inserted into the first cavity 141, and in the state that the gasket body 340 is inserted into the first cavity 141 along the vertical direction, the limiting protrusion 350 can limit the gasket 300 from falling completely into the first cavity 141 under the action of its own gravity, thereby causing the plug-in slot 320 to be separated from the fixed support plate in Figure 41 , and further causing the inner wall of the first cavity 141 to fail to reliably transmit the force to the fixed support plate 220.

[0238] It should be noted that, as shown in Figure 43 , the limiting protrusion 350 can extend out of the first cavity 141 in any direction perpendicular to the depth direction of the first cavity 141, for example, the limiting protrusion 350 extends out of the first cavity 141 along the first direction in Figure 2 , so that the limiting protrusion 350 can abut against the branch wall 130 in Figure 2 , and optionally, the limiting protrusion 350 can also extend into the adjacent metal plates 20 in Figure 1 , so that the limiting protrusion 350 can assist in supporting the metal plates 20; for example, the connecting structure 100 further includes Figure 26The limiting protrusion 350 can also extend along the third direction out of the first cavity 141, and abut against the support wall 183. Figure 26 The limiting protrusion 350 can also extend along the third direction out of the first cavity 141, and abut against the support wall 183.

[0239] In some embodiments, as shown in Figure 44 The outer wall fixing node 10 further comprises a filling block 600 located in the first cavity 141, wherein, in the depth direction of the first cavity 141, the filling block 600 is located between the inner surface of the first cavity 141 and the cushion block 300. By arranging the filling block 600 in the first cavity 141, the filling material in the first cavity 141 can be filled more fully, so that the filling material can more reliably bond the cushion block 300 to the inner surface of the first cavity, and the amount of filling material used can be reduced. Figure 44 As shown in

[0240] In some embodiments, as shown in Figure 45 The outer wall fixing node 10 further comprises at least two plugs 60, each plug 60 being located in the first cavity 141, wherein, in the third direction (the third direction being indicated by the arrow in Figure 45 The first cavity 141 between at least two adjacent plugs 60 contains the fixing support plate 220 and the filling material, i.e., the fixing support plate 220 is fixed in the first cavity 141 by the filling material, and the filling material is blocked between the two plugs 60 in the third direction by the plugs 60, so that the fixing support plate 220 and the connecting structure 100 are reliably fixed without the need for a gasket. Optionally, in the third direction, as shown in Figure 51 The first cavity 141 extends through the extension wall 120 from one end to the other end.

[0241] Optionally, the two plugs 60 form a group of plugs, and multiple groups of plugs are arranged in the first cavity 141 in the third direction, and each group of plugs 60 can be connected to the fixing 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.

[0242] In some embodiments, as shown in Figure 45 The third direction is indicated by the arrow in Figure 45As 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.

[0243] In some embodiments, such as Figure 46 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 46 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 46 As 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 some 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.

[0244] In some embodiments, such as Figure 47 As shown, in third-party direction (third-party direction such as...) Figure 47 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.

[0245] In some embodiments, combined with Figure 48 and Figure 49The outer surface of the latch 60 has a second hollow structure 61 and / or the latch 60 is a hollow structure, so that the latch 60 is lighter in weight.

[0246] In some embodiments, as shown in Figure 50 , the outer wall fixing node 10 further comprises a thermal insulation pad 400 located between the connecting body 210 and the connecting structure 100, for filling the gap between the connecting body 210 and the connecting structure 100, i.e. the thermal insulation pad 400 is clamped between the connecting body 210 and the connecting structure 100, so as to further improve the thermal insulation capacity of the outer wall fixing node 10, and by adjusting the thickness of the thermal insulation pad 400, the height position of the connecting structure 100 can also be fine-tuned. Optionally, as shown in Figure 50 , the limiting protrusion 350 extends in the first direction (the first direction is indicated by the arrow in Figure 50 ), and in the first direction, the end of the thermal insulation pad 440 forms an abutting portion 441 for abutting with the limiting protrusion 350, and in the direction perpendicular to the first direction, the abutting portion 441 is located between the branch wall 130 and the limiting protrusion 350, and the depth of the pad 300 extending into the first cavity 141 can be controlled by the thickness of the abutting portion 441.

[0247] In some embodiments, in combination with Figure 51 and Figure 52 , the outer wall fixing node further comprises a thermal insulation strip 500, which is located on both sides of the connecting plate 200 in the horizontal direction and perpendicular to the first direction (the first direction is indicated by the arrow in Figure 51 ), and it can be understood that in the horizontal direction, the thermal insulation strip 500 is used to fill the space between two adjacent outer wall fixing nodes 10, so as to further improve the thermal insulation capacity of the outer wall fixing node 10. Optionally, in the vertical direction, two connecting structures 100 are located on both sides of the connecting plate 200, forming a mounting space of the connecting plate 200 between the two connecting structures 100, and the outer shape of the thermal insulation strip 500 is the same as the outer shape of the mounting space, so as to reduce the risk of assembly interference between the thermal insulation strip 500 and the connecting structure 100, and in the third direction in Figure 20 , the thermal insulation strip 500 can also abut against the fixed branch plate 220 and the pad 300 in the first cavity 141, so as to reduce the risk of the fixed branch plate 220 and the pad 300 being pulled out of the first cavity 141 in the third direction.

[0248] Optionally, the thermal insulation strip 500 is an integral structure, so as to improve the structural strength and thermal insulation capacity of the thermal insulation strip 500; optionally, as shown in Figure 53 , the thermal insulation strip 500 comprises a first thermal insulation portion 510 and a second thermal insulation portion 520, and the first thermal insulation portion 510 and the second thermal insulation portion 520 are respectively used to cover Figure 23The different parts of the connecting plate 200 are described below. Figure 36 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. For ease of explanation, the connecting plate 200 is positioned close to... Figure 1 One side of the metal plate 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 1 The distance between the metal plate 20 and the wall 30 is different. In order for the connecting plate 200 to adapt to different distances between the metal plate 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.

[0249] In some embodiments, Figure 54 The external wall fixing node 10 includes multiple fixing plates 200 arranged at intervals. Multiple connecting structures 100 are spliced ​​to form a connecting frame 50. The connecting frame 50 is connected to the multiple connecting plates 200 to form the external wall fixing node 10, thereby enabling the connecting frame 50 to connect the multiple connecting plates 200 into a whole, thus allowing the multiple connecting plates 200 to jointly bear the load. Figure 1 The force applied by the metal plate 20 in the middle improves the reliability of the external wall fixing node 10. At the same time, the folded edge of the metal plate 20 is inserted into the slot 121 of each connecting structure 100 of the connecting frame 50.

[0250] In some embodiments, such as Figure 55As shown, along the extension direction of the connecting body 210, the first end of the connecting body 210 extends into the gap between the two adjacent metal plates 20, and the connection of the connecting body 210 and the fixing glue can improve the structural strength of the metal outer wall structure. The part of the connecting body 210 extending into the two metal plates 20 can also support the metal plate 20 above to a certain extent, thereby further improving the strength of the metal outer wall structure. Moreover, the fixing glue can be more fully filled in the space between the two metal plates 20 by extruding the fixing glue through the connecting body 210, which can not only make the fixing between the two metal plates 20 more reliable but also reduce the use amount of the fixing glue. Optionally, as shown in Figure 55 As shown, the heat insulation filling structure 70 is located in the gap between the adjacent metal plates 20, and the filling structure 70 forms an interference fit with the gap to improve the heat insulation capacity of the metal outer wall structure.

[0251] In some embodiments, as shown in Figure 56 As shown, in the horizontal direction, a wall gap 201 is formed between the two metal plates 20, and the two outer wall fixing nodes 10 are located on the two sides of the wall gap 201. The two spaced outer wall fixing nodes 10 can reduce the assembly interference between the outer wall fixing nodes 10 and reduce the assembly difficulty.

[0252] In some embodiments, as shown in Figure 57 As shown, the two outer wall fixing nodes 10 span the wall gap 201 and are integrated, which can be understood as that the two outer wall fixing nodes 10 located on the two sides of the wall gap 201 form a two-in-one structure in the horizontal direction, thereby forming a more reliable structure at the wall gap 201 and improving the structural stability of the outer wall structure. It should be noted that, according to the connection mode of the connecting plate 200 and the wall body 30, Figure 1 The two outer wall fixing nodes 10 are integrated in different forms according to different connection modes of the connecting plate 200 and the wall body 30. The structure of the two outer wall fixing nodes 10 being integrated will be exemplarily described below. Figure 56 to Figure 59 As shown in

[0253] As shown, the two connecting plates 200 are fixedly connected with the two fixed plates 700, and the two fixed plates 700 are fixedly connected with the wall body 30 and span the wall gap 201 and are integrated; as shown in Figure 58 As shown, the connecting plate 200 is directly fixed to the wall body 30, as shown in Figure 57 As shown, the two connecting plates 200 span the wall gap 201 and are integrated, and it should be noted that, for the connecting plate 200 spanning the wall gap 201 and being connected with the connecting structure 100 in the two connecting frames 50 at the same time, and the connecting plate 200 extruding the fixing glue through the connecting structure 100, Figure 59 Figure 60 Figure 1 ​​As shown, the connecting structure 100 is connected with the connecting plate 200, that is, the connecting plate 200 is connected with the connecting plate 200 through the filling material and the filling material is blocked between the two plugs 60 through the two plugs 60, and the end of the connecting structure 100 needs to be provided with a blocking structure which can allow the fixed supporting plate 220 to pass through and block the filling material in the first cavity 141 together with the fixed supporting plate 220 after the fixed supporting plate 220 is assembled.

[0254] As shown, the wall gap 201 is formed between the two metal plates 20, the connecting plate 200 of the single external wall fixing node 10 spans the wall gap 201, and the external wall fixing node 10 is fixedly connected with the two metal plates 20 in the horizontal direction, wherein the external wall fixing node 10 comprises a connecting plate 200 and at least two connecting structures 100, the connecting plate 200 is directly fixedly connected with the wall 30 in the wall gap 201, and the two connecting structures 100 are fixedly connected with the two metal plates 20 respectively. Figure 61 Figure 1 As shown, the wall gap 201 is formed between the two metal plates 20, the connecting structure 100 of the single external wall fixing node 10 spans the wall gap 201, and the external wall fixing node 10 is fixedly connected with the two metal plates 20 in the horizontal direction, wherein the external wall fixing node 10 comprises a connecting plate 200, a fixed plate 700 and two connecting structures 100, the two connecting structures 100 are fixedly connected with the metal plates 20 on both sides of the wall gap 201 respectively, the connecting plate 200 and the fixed plate 700 span the wall gap 201, and the connecting plate 200 is fixedly connected with the two connecting structures 100.
