Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to an external wall fixing node and an external wall structure. Background Technology

[0002] Building exterior walls refer to the outermost part of a building that is in direct contact with the outdoor environment. Exterior walls serve functions such as building protection, regulating indoor and outdoor temperatures, waterproofing, sound insulation, and providing an aesthetically pleasing appearance. In related exterior wall structures, wall panels need to be fixed to the wall via exterior wall fixing nodes. To ensure that these fixing nodes meet the spacing requirements between the wall panels and the wall, assembly interference can easily occur. Utility Model Content

[0084] 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.

[0085] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0086] 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.

[0087] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0088] In the following specific embodiments, the wall panels in the exterior wall structure can be made of any material. For example, the wall panels can be one or more combinations of metal panels, tempered glass panels, ceramic tiles, stone slabs, and concrete slabs. The wall panels can be fixed to the wall in a dry-hanging, wet-hanging, or partially dry-hanging and partially wet-hanging manner. Depending on the specific structure of the exterior wall structure, it can be used to achieve various functions. For example, a heat-insulating filling layer can be used in the exterior wall structure to achieve heat insulation or thermal insulation; a vacuum insulation layer can be used in the exterior wall structure to achieve sound insulation; and wall decorations can be added to the exterior wall structure to improve the aesthetics of the building. The above structures can also be used in combination to enable the exterior wall structure to achieve multiple functions simultaneously. The following examples illustrate different components in the exterior wall structure and the overall structure of the exterior wall structure.

[0089] First, combine Figure 1 Describe the usage environment of the exterior wall structure, 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 exterior wall fixing node 10 will be described exemplarily below with reference to various embodiments.

[0090] In some embodiments, such as Figure 2 As shown, the external wall fixing node 10 includes: a connecting structure 100, a connecting plate 200, and a gasket 300. The connecting structure 100 surrounds and forms a first cavity 141, and the connecting structure 100 is used to connect with... Figure 1The wall panel 20 is fixedly connected to the connecting structure 100. The connecting plate 200 includes a connecting body 210 and a fixed support plate 220. The fixed support plate 220 extends from the outer surface of the connecting body 210 and extends into the first cavity 141. That is, by extending the fixed support plate 220 into the first cavity 141, the connecting plate 200 is fixedly connected to the connecting structure 100. This allows the weight of the wall panel 20 to be transferred to the connecting plate 200 through the force between the fixed support plate 220 and the inner surface of the first cavity 141. Simultaneously, the connecting plate 200 and... Figure 1 The wall 30 is fixedly connected, thereby fixing the wall panel 20 to the wall 30.

[0091] Meanwhile, the gasket 300 has a slot 310, and the gasket 300 is sleeved on the outside of the fixed support plate 220 through the slot 310 and is located inside the first cavity 141. The fixed support plate 220 abuts against the inner surface of the first cavity 141 through the gasket 300, so that the weight of the wall panel 20 supported by the connecting structure 100 can be more reliably transferred to the fixed plate 200; wherein, the gasket 300 includes various types, in the first direction (the first direction is as follows) Figure 2 As shown by the middle arrow, the dimensions of each type of gasket 300 are the same as the dimensions of the first cavity 141. Furthermore, in the first direction, the distance between the slot 310 and the edge of the gasket 300 differs for each type of gasket 300; that is, the slots 310 in different types of gaskets 300 are located in different positions. The following section will discuss this further. Figure 3 The differences in slots 310 for different types of gaskets 300 are illustrated by way of example. It should be noted that... Figure 3 The image shown only displays some types of gaskets 300, not all types of gaskets 300. Figure 3 As shown, various types of gaskets 300 are in the first direction (the first direction is as follows). Figure 3 The dimensions (indicated by the middle arrow) are the same, for example, 20 mm, and each type of gasket 300 in the first direction has an edge 320. Figure 3 The spacing between the slot 310 and the edge 320 in different types of gaskets 300 are respectively a first spacing D1, a second spacing D2, and a third spacing D3. This spacing can be understood as the distance between the axis L1 of the slot 310 perpendicular to the first direction and the edge 320. For example, the first spacing D1 is 10 mm, the second spacing D2 is 8 mm, and the third spacing D3 is 5 mm. The following will be combined with... Figure 4 The function of setting various types of gaskets 300 is explained.

[0092] like Figure 4 As shown, the wall panel 20 and wall 30 in the external wall structure are in the first direction (the first direction is as shown in the figure). Figure 4As indicated by the middle arrow, the spacing between the outer wall structure 20 and the wall 30 is S1. In the first direction, the distance from the end of the connecting structure 100 fixed to the wall panel 20 to the first cavity 141 near that end is S2. The size of the first cavity 141 is S3. The distance from the fixed support plate 220 to the inner surface of the first cavity 141 on the side away from the wall panel 20 is S4. The distance from the fixed support plate 220 to the side of the connecting body 210 near the wall 30 is S5. By making S2 + S3 + S5 - S4 = S 1. The external wall fixing node 10 can be adapted to the distance between the wall panel 20 and the wall 30 in the first direction. If only one type of shim 300 is used, the position of the slot 310 in the shim 300 and the distance between the edge of the shim 300 are not adjustable. This results in the relative position between the fixing plate 220 and the first cavity 141 being unadjustable. That is, the four dimensions S2, S3, S5 and S4 cannot be adjusted. These four dimensions need to be accurately controlled to make the external wall fixing node 10 adapt to the distance between the wall panel 20 and the wall 30 in the first direction. The distance between the wall panel 30 and the wall 30, processing errors, or assembly errors can easily lead to assembly interference of the external wall fixing node 10. For example, the gasket 300 may not be able to be installed in the first cavity 141 or the fixing plate 220 may not be able to be inserted into the slot 310. In this application, by setting various types of gaskets 300, the slot 310 is positioned differently in different types of gaskets 300, thereby allowing the position of the fixing plate 220 in the first cavity 141 to be adjustable. Selecting different types of gaskets 300 according to the position of the fixing plate 220 in the first cavity 141 can enable the fixing plate 220 to be fixedly connected to the gasket 300. It can be understood that by allowing the position of the fixing plate 220 in the first cavity 141 to be adjustable, S4 can be adjusted within a large size range, thereby absorbing the changes in S2, S3, and S5 caused by processing errors or assembly errors through S4. While ensuring that the external wall fixing node 10 can meet the distance requirements between the wall panel 20 and the wall 30, the risk of assembly interference of the external wall fixing node 10 is reduced.

[0093] Optional, such as Figure 3 As shown, in various types of gaskets 300, the distance between the slot 310 and the edge 320 is maximized when the axis of the slot 310 perpendicular to the first direction coincides with the axis of the gasket 300 perpendicular to the first direction. By flipping the gasket 300 relative to its axis perpendicular to the first direction, the slot 310 can meet the positional requirements of the fixed support plate 220. For example, Figure 4The first cavity 141 has a central axis perpendicular to the first direction. For ease of explanation, the side of the central axis of the first cavity 141 away from the wall panel 20 is called the "away side," and the side of the central axis closer to the wall panel 20 is called the "closer side." If the fixing plate 220 is located on the closer side of the first cavity 141, then when assembling the gasket 300, the edge 320 is positioned on the closer side of the first cavity 141, and the corresponding model of gasket 300 is selected and assembled with the fixing plate 220 according to the position of the fixing plate 220 in the first cavity 141. If the support plate 220 is located on the side away from the first cavity 141, the edge 320 is positioned on the side away from the first cavity 141 by flipping the shim 300. The shim 300 of the corresponding model is selected according to the position of the fixed support plate 220 in the cavity 141 and assembled with the fixed support plate 220. It can be understood that by flipping the shim 300, the required model of the shim 300 can be reduced while the shim 300 can meet the different positions of the fixed support plate 220 in the first cavity 141, thereby reducing the overall manufacturing cost of the external wall fixed node 10.

[0094] This utility model provides an exterior wall fixing node, which is applied to an exterior wall structure. The fixing node includes a connecting structure forming a first cavity, and a connecting plate including a connecting body and a fixing support plate. One end of the connecting structure is fixedly connected to a wall panel in the exterior wall structure, the fixing support plate extends into the first cavity, and the end of the connecting body away from the wall panel is fixedly connected to the wall in the exterior wall structure. Thus, the wall panel and the wall are fixedly connected through the fixing node. Furthermore, the fixing node also includes a gasket with a slot. The gasket is fitted onto the fixing support plate through the slot and is located within the first cavity, contacting the inner surface of the first cavity, thereby fixing the exterior wall... The gravity can be transmitted to the connecting body more stably; the gaskets include various types, and the size of each type of gasket in the first direction is the same as the size of the first cavity, so that each type of gasket can reliably abut against the inner surface of the first cavity. At the same time, the spacing between the slot and the edge of the gasket is different for each type of gasket. By setting different types of gaskets, the relative position of the fixed support plate and the first cavity in the first direction can be adjusted within a large range, and the gasket can still be assembled with the fixed support plate. This can reduce the risk of assembly interference of the external wall fixed node while ensuring that the spacing between the wall panel and the wall is met.

[0095] In some embodiments, such as Figure 5 As shown, the spacing between the slot 310 and the edge 320 in each type of gasket 300 varies in the first step length, for example, the first step length is 1 mm. Figure 5The spacings D11, D21, and D31 between the slot 310 and the edge 320 in the three types of gaskets 300 are 5 mm, 6 mm, and 7 mm, respectively. This can be understood as forming a size series by varying the spacing between the slot 310 and the edge 320 in the same increments. During the assembly of the external wall fixing node 10, the gasket is directly selected from this size series, rather than based on... Figure 4 The fixed support plate 220 and the first cavity 141 are respectively molded to form a gasket 300 with a specific slot 310 position. This not only improves the versatility of the external wall fixed node 10, enabling the external wall fixed node 10 to meet the spacing requirements of the wall panel 20 and the wall 30 in different external wall structures 10, but also reduces the overall manufacturing cost of the external wall fixed node 10 by replacing individual mold manufacturing with size series.

[0096] In some embodiments, such as Figure 6 As shown, in the first direction (the first direction is as follows) Figure 6 As shown by the middle arrow, a clearance fit is formed between the slot 310 and the fixed support plate 220. This can be understood as allowing a certain gap between the sidewalls of the fixed support plate 220 and the slot 310 in the first direction. This allows the relative position between the fixed support plate 220 and the slot 310 to be further fine-tuned within a small size range. By selecting a suitable shim 300 from the size series, the position of the slot 310 and the fixed support plate 220 can be made to correspond within a large size range. At the same time, by forming a clearance fit between the fixed support plate 220 and the slot 310, the position of the slot 310 can be further adjusted within a small tolerance zone, further reducing the risk of assembly interference at the external wall fixing nodes.

[0097] In some embodiments, such as Figure 7 As shown, in the first direction (the first direction is as follows) Figure 7 (As indicated by the middle arrow) On at least one side, the end of the gasket 300 away from the fixed support plate 220 has a guide slope 311. Along the direction of extension of the fixed support plate 220, the cross-sectional area of ​​the gasket 300 decreases, and the cross-section is a plane perpendicular to the direction of extension of the fixed support plate. This can be understood as the guide slope 311 creating a structure where the end of the gasket 300 gradually reduces in cross-sectional area. The gasket 300 and... Figure 2The inner surface of the first cavity 141 is filled with a filling material. By providing a guide slope 311, the filling material can optionally be a slurry, glue, or a mixture of slurry and glue. When the filling material is injected into the first cavity 141, the guide slope 311 can squeeze the filling material to both sides, so that the filling material applies a compressive force to the gasket 300 from both sides of the fixed support plate 220. This compressive force can position the gasket 300 and the fixed support plate 220 in the middle position of the first cavity 141 or press the gasket 300 against the inner surface of the first cavity 141 in the first direction, so that the inner surface of the first cavity 141 can more reliably transmit the force to the gasket 300 and the fixed support plate 220.

[0098] In some embodiments, combined with Figure 8 and Figure 9 Gasket 300 includes a first type gasket 300A and a second type gasket 300B, which will be discussed below in conjunction with... Figure 8 and Figure 9 The two types of gasket structures are described in detail. The structure of the first type of gasket, 300A, is as follows: Figure 8 As shown, in the first direction (the first direction is as follows) Figure 8 As indicated by the middle arrow, the distance between the slot 310 and the edge 320 of the first type gasket 300A is greater than a distance threshold. Furthermore, on both sides of the first type gasket 300A, the ends of the first type gasket 300A away from the fixed support plate 220 have guide slopes 311. That is, when the distance between the slot 310 and the edge 320 is sufficiently far, guide slopes 311 are formed on both sides of the gasket 300 in the first direction, thus forming the first type gasket 300A. By providing guide slopes 311 on both sides, the filling material can apply symmetrical compressive force to the first type gasket 300A on both sides of the first direction, keeping the compressive force applied by the filling material to the first type gasket 300A balanced. This achieves automatic alignment of the first type gasket 300A and the fixed support plate 220 within the first cavity, and also keeps the pressure applied by the filling material on both sides of the first type gasket 300A balanced. The structure of the second type gasket 300B is as follows: Figure 9 As shown, in the first direction (the first direction is as follows) Figure 9 As indicated by the middle arrow, the distance between the slot 310 and the edge 320 of the second type gasket 300B is less than a distance threshold. Furthermore, on the side of the second type gasket 320 furthest from the slot 310 in the first direction, the end of the second type gasket 320 furthest from the fixed support plate 220 has a guide slope 311. That is, when the distance between the slot 310 and the edge 320 is small, the guide slope 311 is only provided on the side furthest from the slot 310 in the first direction. This allows the filling material to be filled using the guide slope 311. Figure 7 While reducing the impact of the slot 310 on the structural strength of the gasket 300 in the first cavity 141, the spacing threshold can be, for example, 1 mm.

[0099] The following is combined Figure 7 The principle of the interaction between the location of the slot 310 and the arrangement of the guide slope 311 is explained below. For ease of explanation, the extension direction of the fixed support plate 220 is referred to as the height direction of the gasket 300. If a guide slope 311 is provided on one side of the edge 320, the height dimension of the gasket 300 decreases as it approaches the edge 320. Furthermore, to ensure reliable insertion between the slot 310 and the fixed support plate 200, the slot 310 must have a sufficiently large height. If the distance between the slot 310 and the edge 320 is small, placing the slot 310 in the area of ​​the gasket 300 where the guide slope 311 is located will result in an excessively small gap between the top of the slot 310 and the guide slope 311, leading to insufficient structural strength in the area between the top of the slot 310 and the guide slope 311. Therefore, when the distance between the slot 310 and the edge 320 is sufficiently large, it is permissible for both sides of the gasket 300 to have guide slopes 311 in the first direction, forming a structure as shown below. Figure 7 The first type of gasket 300A shown, when the spacing of the edges 320 of the slot 310 is small, provides a guide bevel 311 only on the side away from the slot 310 in the first direction, to form as shown in the figure. Figure 8 The second type of gasket, 300B, is shown.

[0100] In some embodiments, such as Figure 10 As shown, the first type of gasket 300A includes multiple first subtype gaskets 300A1, in a first direction (the first direction is as follows). Figure 10 As indicated by the middle arrow, the spacing between the slot 310 and the edge 320 of each first subtype gasket 300A1 is different, and this spacing varies with the same step length. This can be understood as follows: in the first direction, when both sides of the gasket 300 have guide slopes 311, the position of the slot 310 can be adjusted in the first direction with the same step length, thereby forming multiple first type gaskets 300A1. For example... Figure 10 The first subtype gasket 300A1 includes three types of first subtype gaskets 300A1. The distance between the slot 310 and the edge 320 in the three types of first subtype gaskets 300A1 forms three distances D12, D22 and D32 respectively. The three distances are 4 mm, 3 mm and 2 mm respectively. The three distances are represented by the distance between the axis L1 of the slot 310 perpendicular to the first direction and the edge 320.

[0101] In some embodiments, such as Figure 11 As shown, in each of the first subtype gaskets 300A1, the distance between the slot 310 and the edge 320 is positively correlated with the guide angle. The guide angle is the angle between the guide slope 311 on the side closer to the edge 320 and the extension direction of the fixed support plate 220. The following section will discuss this further. Figure 9The positional relationship between the guide angle and the slot 310 is illustrated by way of example. The extension direction of the fixed support plate 220 is parallel to the depth axis L2 of the slot 310. For ease of explanation, the guide angle will be represented below by the angle between the guide ramp 311 and the depth axis L2. Figure 11 In the two first subtype gaskets 300A1, the distances between the slot 310 and the edge 320 in the first direction are D13 and D23, respectively. The two distances are 4 mm and 3 mm, respectively, and the corresponding guide angles are θ1 and θ2, respectively. The two guide angles are 20 degrees and 13 degrees, respectively.

[0102] The following is combined Figure 7 The principle of the correspondence between the slot 310 and the guide angle is explained. In the first direction, the guide slope 311 causes the height dimension of the pad 300 to decrease in the direction close to the edge 320. The smaller the guide angle, the smaller the rate of decrease. By making the distance between the slot 310 and the edge 320 positively correlated with the guide angle, the closer the slot 310 is to the edge 320, the smaller the rate of decrease in the height dimension of the pad 300. This makes the distance between the top of the slot 310 and the guide slope 311 large enough, thereby further reducing the impact of the guide slope 311 on the structural strength of the pad 300.

[0103] In some embodiments, such as Figure 12 As shown, gasket 300 also includes a third type gasket 300C, in the first direction (the first direction is as shown in the figure). Figure 12 As indicated by the middle arrow, the slot 310 is adjacent to the edge 320, and on the side away from the slot 310 in the first direction, the third type gasket 300C has a guide slope 311, that is, the edge of the slot 310 can extend to the edge 320, so that the slot 310 can be adjusted within a larger size range. At the same time, on the side away from the slot 310, there is also a guide slope 311, which can help the filling material fill the first cavity 141, thereby enabling the inner wall of the first cavity 141 to more reliably transmit the force to the fixed support plate 220.

[0104] In some embodiments, such as Figure 13 As shown, the connecting plate 200 includes different types, and the length of the connecting body 210 in each type of connecting plate 200 is different. This can be understood as setting the length of the connecting body 210 to different dimensions, according to... Figure 1 The spacing between the wall panel 20 and the wall 30 can be adjusted by selecting a corresponding model of connecting plate 200, thereby enabling... Figure 1 The external wall fixing node 10 can meet the spacing requirements of the wall panel 20 and the wall 30, thus improving the versatility of the external wall fixing node 10.

[0105] In some embodiments, such as Figure 13As shown, the length of the connecting body 210 in each type of connecting plate 200 varies with the same second step length. For example, the connecting body 210 is along a second direction (the second direction is as follows). Figure 13 As shown by the middle arrow, the dimension of the connecting body 210 in the second direction is the length dimension of the connecting body 210. Figure 13 The lengths of the connecting bodies 210 in the three types of connecting plates 200 are M1, M2, and M3, respectively. These three lengths are 48 mm, 52 mm, and 56 mm, respectively. That is, the second step length can be, for example, 4 mm. It should be noted that by varying the length of the connecting bodies 210 with the same second step length, it can be understood that a size series is formed by varying the length of the connecting bodies 210 with the same step length. During the assembly of the external wall fixing nodes 10, the dimensions are directly selected from this size series, rather than based on... Figure 1 The distance between the wall panel 20 and the wall 30 determines the length of the connecting body 210, and a connecting plate 200 of a specific size is manufactured separately by opening a mold. This not only improves the versatility of the external wall fixing node 10, enabling the external wall fixing node 10 to meet the distance requirements of the wall panel 20 and the wall 30 in different external wall structures 10, but also reduces the overall manufacturing cost of the external wall fixing node 10 by replacing separate mold manufacturing with a size series.

[0106] Optionally, the second step is longer than the first step, that is, Figure 13 The length adjustment step of the connecting body 210 in the different types of connecting plates 200 is greater than Figure 3 The adjustment step size of the spacing between the slot 310 and the edge 320 in the different types of gaskets 300 allows for faster changes in the length of the connecting body 210 through a second step size change, and through a larger change step size... Figure 1 The length of the external wall fixing node 10 is adjusted to approximately match the spacing between the wall panel 20 and the wall 30, and then... Figure 2 The fixed support plate 220 is positioned within the first cavity 141 such that the length of the external wall fixing node 10 is the same as the distance between the wall panel 20 and the wall 30, reducing the number of dimensions in the connecting body 210 and thus lowering the overall manufacturing cost of the external wall fixing node 10. At the same time, by adjusting the distance between the slot 310 and the edge 320 in the gasket 300 with a smaller step length, the position of the slot 310 in the gasket 300 can be adjusted with high precision within a small range according to the position of the fixed support plate 220 within the first cavity 141. This ensures that the size of the external wall fixing node 10 meets the distance between the wall panel 20 and the wall 30 while reducing the risk of assembly interference of the external wall fixing node 10.

[0107] In some embodiments, such as Figure 14As shown, the connecting body 210 is along the second direction (the second direction is as follows). Figure 14 Extending in the second direction (as indicated by the middle arrow), the connecting body 210 has opposing first end 211 and second end 212, with the first end 211 closer to... Figure 1 Wall panel 20, of which, such as Figure 15 As shown, in each type of connecting plate 200, the distance between the first end 211 of the connecting body 210 and the fixed support plate 220 is the same, while the distance between the second end 212 and the fixed support plate 220 is different. That is, the distance between the second end 212 of the connecting body 210 and the fixed support plate 220 in each type of connecting plate 200 varies with the same second step, thereby forming a series of sizes for the connecting plates 200. It can be understood that the series of sizes for the connecting plates 200 is formed by varying the distance between the second end 212 and the fixed support plate 220, while keeping the distance between the first end 211 and the fixed support plate 220 constant. For example, Figure 14 The distances between the second end 212 of the connecting body 210 and the fixed support plate 220 in the three types of connecting plates 200 are M11, M21 and M31 respectively, which are 42 mm, 44 mm and 46 mm respectively. Meanwhile, the distance between the first end 211 of the connecting body 210 and the fixed support plate 220 in the three types of connecting plates 200 is M4, which is 8 mm.

[0108] The following is combined Figure 4 The principle of keeping the distance between the first end 211 and the fixed support plate 220 constant will be explained below. For ease of explanation, the following will be... Figure 14 The distance between the first end 211 and the fixed support plate 220 is called the front end dimension of the connecting body 210, and the distance between the second end 212 and the fixed support plate 220 is called the rear end dimension of the connecting body 210. Since the fixed support plate 220 is located inside the first cavity 141, the length dimension of the external wall fixing node 10 is mainly related to the rear end dimension of the connecting body 210 and the distance between the first cavity 141 and the mating end of the connecting structure 100, that is, Figure 4 S2 and S5 in the diagram have a major impact on the size of the external wall fixing node 10. The front end size of the connecting body 210 has a smaller impact on the size of the external wall fixing node 10. This makes the front end size of the connecting plates 200 of all types the same, which can further reduce the overall manufacturing cost of the external wall fixing node 10. At the same time, if the front end size of the connecting body 210 changes with the length of the connecting body 210, the front end size of the connecting body 210 will also be longer when the length of the connecting body 210 is longer. An excessively long front end size will cause the second end 212 to protrude from the wall panel 20, which will make the assembly of the external wall fixing node 10 difficult.

[0109] In some embodiments, such as Figure 15 As shown, the connecting body 210 is along the second direction (the second direction is as follows). Figure 15 Extending in the second direction (as indicated by the middle arrow), the connecting body 210 has opposing first end 211 and second end 212, the first end 211 being close to the wall panel 20, and the second end 212 being used to connect with... Figure 1 The wall 30 of the exterior wall structure is fixedly connected, that is, the connecting body 210 is connected to the wall 30 through the second end 212. Figure 1 The wall 30 is fixedly connected, wherein the second end 212 can be directly fixed to the wall 30, or the second end 212 can be indirectly fixed to the wall 30. The following describes the connection in conjunction with... Figure 15 and Figure 16 The above-mentioned forms of direct fixation and indirect fixation are illustrated by examples respectively.

[0110] like Figure 15 As shown, the second end 212 is directly fixedly connected to the wall 30. For example, an extension plate 213 is formed at the second end of the connecting body 210. The extension plate 213 is directly fixed to the wall 30 by expansion bolts. In this state, the distance between the wall panel 20 and the wall 30 is small. Fixing adhesive can be set between the wall panel 20 and the wall 30, so that the wall panel 20 can also form a fixed connection with the wall 30 through the fixing adhesive, that is, the wall panel 20 and the wall 30 form a wet hanging structure.

[0111] like Figure 16 As shown, the external wall fixing node 10 also includes a fixing plate 400, which is used to fix and connect to the wall 30. The second end 212 is fixedly connected to the wall 30 through the fixing plate 30. That is, the second end 212 is indirectly fixedly connected to the wall 30 through the fixing plate 400. In this state, the distance between the wall panel 20 and the wall 30 is relatively far, and no fixing adhesive can be set between the wall panel 20 and the wall 30. The wall panel 20 and the wall 30 are fixed by the force between the second end 212 and the fixing plate 400, that is, the wall panel 20 and the wall 30 form a dry-hanging structure. The second end 212 and the fixing plate 400 can be fixedly connected in any way. For example, when the wall panel 20 is an ultra-light foam board structure, the second end 212 can be bonded to the fixing plate 400 by structural adhesive. For example, the second end 212 can also be connected by bolts. For example, the second end 212 can also be fixedly connected to the fixing plate 400 by hooks.

[0112] In some embodiments, combined with Figure 17 and Figure 18 The fixing plate 400 includes a first type fixing plate 400A and a second type fixing plate 400B, such as Figure 17 As shown, the first type of fixing plate 400A includes a plate body 410, and a second end 212 is directly connected to the plate body 410, as shown. Figure 18 As shown, the second type of fixing plate 400B includes a plate body 410 and a fixing protrusion 420, the fixing protrusion 420 being directed away from the plate body 410 and ... Figure 1 The wall 30 protrudes from the plate body 410 in the direction of the wall, and the fixed protrusion 420 is along the third direction (the third direction is as follows). Figure 18 Extending from the middle arrow, it can be understood that for dry-hanging exterior wall structures, it can be based on... Figure 1 The spacing between the wall panel 20 and the wall 30 is determined by selecting either a first type of fixing plate 400A or a second type of fixing plate 400B. Specifically, when the spacing between the wall panel 20 and the wall 30 is small, the first type of fixing plate 400A is selected, and when the spacing between the wall panel 20 and the wall 30 is large, the second type of fixing plate 400B is selected, so that the external wall fixing node 10 meets the spacing requirements between the wall panel 20 and the wall 30.

[0113] Optional, such as Figure 19 As shown, the second type of fixing plate 400B includes various subtypes of fixing plates, in the third-party direction (such as the third-party direction...). Figure 19 As shown by the middle arrow, the lengths of the fixing protrusions 420 on each subtype of fixing plate are different. For example, Figure 19 The lengths of the fixing protrusions 420 in the three types of fixing plates shown are N1, N2 and N3, respectively. The three lengths are 10 mm, 25 mm and 30 mm. By selecting different types of fixing plates, the external wall fixing node 10 can further meet the spacing requirements of the wall panel 20 and the wall 30, and further improve the versatility of the external wall fixing node 10.

[0114] Optional, such as Figure 20 As shown, the lengths of the fixing protrusions 420 in each subtype of fixing plate vary with the same third step. For example, the lengths of the fixing protrusions 420 in each subtype of fixing plate are N11, N21, and N31, respectively. These three lengths are 10 mm, 20 mm, and 30 mm, respectively. That is, the third step can be, for example, 10 mm. It can be understood that by making the length of the fixing protrusions 410 vary with the same step, a size series is formed. During the assembly of the external wall fixing node 10, the protrusions are directly selected from this size series, rather than based on the dimensions of the fixing protrusions 410. Figure 1 The distance between the wall panel 20 and the wall 30 determines the length of the fixed protrusion 420, and a fixed plate 400 of a specific size is manufactured separately by opening a mold. This not only improves the versatility of the external wall fixed node 10, enabling the external wall fixed node 10 to meet the distance requirements of the wall panel 20 and the wall 30 in different external wall structures 10, but also reduces the overall manufacturing cost of the external wall fixed node 10 by replacing separate mold manufacturing with a size series.

[0115] Optionally, the third step is longer than the first step, which can be understood as... Figure 20 The length adjustment step of the fixing protrusion 420 in the different subtype fixing plates is greater than Figure 3The adjustment step size of the spacing between the slot 310 and the edge 320 in the different types of gaskets 300, through the change of the third step size, allows the fixed protrusion 420 to change more quickly, and through a larger change step size, Figure 1 The length of the external wall fixing node 10 is adjusted to roughly fit the distance between the wall panel 20 and the wall 30. Then, by fixing the position of the support plate 220 in the first cavity 141, the length of the external wall fixing node 10 is made the same as the distance between the wall panel 20 and the wall 30. This reduces the number of fixing plates in the size series, thereby reducing the overall manufacturing cost of the external wall fixing node 10. At the same time, by adjusting the distance between the slot 310 and the edge 320 in the shim 300 with a smaller first step length, the position of the slot 310 in the shim 300 can be adjusted with high precision within a small range according to the position of the support plate 220 in the first cavity 141. This ensures that the size of the external wall fixing node 10 meets the distance between the wall panel 20 and the wall 30, while reducing the risk of assembly interference of the external wall fixing node 10.

[0116] Optionally, the third step length is greater than the second step length, that is, through Figure 20 The size variation step of the fixed protrusion 420 in the middle, Figure 13 The length variation step of the connecting body 210 in the middle, and Figure 3 The spacing between the slot 310 and the edge 320 varies with different step lengths, thus forming three combinations of size variations. Different lengths can be formed by splicing different second and third step lengths, so that the external wall fixing node 10 can adapt to different dimensions. Figure 1 The different spacing between the wall panel 20 and the outer wall 30 further improves the versatility of the outer wall fixing node. At the same time, by using a smaller first step length, a small-range high-precision adjustment is made according to the position of the fixing plate 220 in the first cavity 141, so that the size of the outer wall fixing node 10 can meet the spacing between the wall panel 20 and the wall 30, while reducing the risk of assembly interference of the outer wall fixing node 10.

[0117] In some embodiments, such as Figure 21 As shown, a cutout 430 exists between the fixing protrusion 420 and the plate body 410, thereby reducing the weight of the fixing plate 400 and thus reducing the weight of the plate. Figure 1 The self-weight of the external wall fixing node 10 improves the fixing reliability of the wall panel 20.

[0118] In some embodiments, such as Figure 22 As shown, the fixing plate 400 also has a first hook 440, and the second end 212 also has a second hook 214. The first hook 440 can hook onto the second hook 214 so that the second end 212 is fixedly connected to the fixing plate 400. This can be understood as the fixing plate 400 being fixed to the wall during the construction of the exterior wall structure. Figure 1 At the target location of wall 30, after fixing wall panel 20, connecting structure 100, and connecting plate 200 to form a wall panel assembly, the entire wall panel assembly is hooked onto fixing plate 400 via a hook structure. This facilitates both the installation and positioning of wall panel 20 and the overall hooking of the wall panel assembly onto fixing plate 400, thereby reducing the construction difficulty of the external wall structure. Optionally, such as... Figure 22 As shown, the first hook 440 and the second hook 214 form a clearance fit, that is, there is a certain gap between the first hook 440 and the second hook 214, so as to facilitate the hooking of the two hooks and further reduce the risk of assembly interference at the external wall fixing nodes.

[0119] In some embodiments, such as Figure 23 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.

[0120] In some embodiments, the connection structure 100 is a split structure, for example, such as... Figure 24 As shown, the connecting structure 100 includes a first part 151 and a second part 152. The first part 151 includes a portion of a branch wall 130 and an extension wall 120 for surrounding the formation of the first cavity 141, and the extension wall 120 is used for connecting with... Figure 1 The portion of the wall panel 20 that is fixed therein, as well as the branch wall 130 and part of the extension wall 120 that surround the first cavity 141, are all integrally formed, that is, for fixed connection with the wall panel 20 and for connection with... Figure 1 The portion of the connecting plate 200 that is fixedly connected forms an integral first part 151. The weight of the wall panel 20 can be reliably transferred to the connecting plate 200 through the first part 151, improving the reliability of the external wall fixing node 10. At the same time, the other parts of the extension wall 120 form a second part 152. By setting a split connecting structure 100, different materials can be used for different parts of the connecting structure 100. That is, according to the different load-bearing requirements of different parts, different materials can be set for different parts of the connecting structure 100, thereby meeting the load-bearing requirements of the connecting structure 100 while reducing the manufacturing cost of the connecting structure 100. For example, the material of the first part 151 is metal, and the material of the second part 152 is a polymer, such as nylon, plastic, or a mixture of nylon and plastic.

[0121] 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 connection structure 100.

[0122] In some embodiments, such as Figure 25 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 25 Arranged sequentially on the (as indicated by the middle arrow), the third part 153 is used to realize 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.

[0123] In some embodiments, such as Figure 26 As shown, the connection structure 100 includes: a mating wall 110, an extension wall 120, and a branch wall 130. The extension wall 120 extends from the surface of the mating wall 110 opposite to the mating surface 111, that is, from the surface of the mating wall 110 towards the mating surface 111. Figure 1 The wall 30 extends outwards, and at the same time, the extension wall 120 extends along the first direction (the first direction is as follows). Figure 2 (As indicated by the solid arrow in the middle) The first direction is not parallel to the mating surface 111, so that the extension wall 120 can extend away from the mating wall 110. Optionally, the extension wall 120 forms an acute angle with the mating surface 111. When assembling the wall panel 20, the extension wall 120 is tilted upward, that is, the end of the extension wall 120 fixed to the mating wall 110 is higher than the other end that extends. After the wall panel 20 is assembled, the tilted extension wall 120 is pressed down by the gravity of the wall panel 20, thereby applying prestress to the wall panel 20, improving the load-bearing capacity of the extension wall 120, and thus improving the reliability of the wall panel 20 fixing. Optionally, the first direction is perpendicular to the mating surface 111, so as to make full use of the size of the extension wall 120 to facilitate fixing with the wall 30. Moreover, setting the first direction to be perpendicular to the mating surface 111 can also facilitate the positioning when installing the wall panel 20. The following structural description will be based on the first direction being perpendicular to the mating surface 111.

[0124] The branch wall 130 extends from the outer surface of the extension wall 120, wherein the branch wall 130 and the extension wall 120 surround and form the first cavity 141. Figure 2The fixed support plate 220 extends into the first cavity 141 to fix the connection between the connecting structure 100 and the connecting plate 200. With the connecting structure 100 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.

[0125] At the same time, the fitting wall 100 has the property of being in contact with... Figure 1 The bonding surface 111 of the wall panel 20 is used to increase the fixed area between the wall panel 20 and the connecting structure 100, thereby further improving the connection reliability between the wall panel 20 and the connecting structure 100.

[0126] In some embodiments, such as Figure 27 As shown, the mating surface 111 forms a mating cavity 112, the mating cavity 112 has an opening 113, 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 27 As indicated by the middle arrow, that is, in the state of being assembled with the wall panel 20, the opening of the fitting cavity 112 faces... Figure 1In the wall panel 20, the bonding cavity 112 is used to accommodate structural adhesive. The bonding surface 111 is bonded to the wall panel 20 through the structural adhesive. By setting the bonding cavity 112, the bonding surface 111 can accommodate more structural adhesive and concentrate the structural adhesive in the space where the bonding surface 111 contacts the wall panel 20. This allows more structural adhesive to participate in the fixed connection between the bonding surface 111 and the wall panel 20, and also prevents the structural adhesive from being squeezed out of the contact space between the bonding surface 111 and the wall panel 20. This allows the bonding surface 111 to bond more reliably with the wall panel 20, further improving the reliability of the external wall fixing node 10. It should be noted that the bonding surface 111 can form the bonding cavity 112 in different ways. For example, the bonding cavity 112 can be formed by the concavity of the bonding surface 111. For example, the bonding cavity 112 can also be formed by a protruding structure surrounding the bonding surface 111.

[0127] In some embodiments, such as Figure 28 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 28 (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.

[0128] Optional, such as Figure 28 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.

[0129] This utility model embodiment also provides an exterior wall structure, which is applied to buildings. The structure and function of the exterior wall structure are described below with reference to various embodiments.

[0130] In some embodiments, such as Figure 1 As shown, the exterior wall structure includes: an exterior wall fixing node 10, a wall panel 20, and a wall body 30. The wall panel 20 is attached to the mating surface 111, and the wall body 30 is fixedly connected to the second end of the connecting body 210. This can be understood as the wall panel 20 being fixedly connected to the connecting structure 100, the connecting plate 200 being fixedly connected to the connecting structure 100, and the wall body 30 being fixedly connected to the connecting plate 200, thus fixing the wall panel 20 to the wall body 30. Vertically, two connecting structures 100 are fixedly connected to adjacent wall panels 20. The two fixing support plates 220 of the connecting plate 200 extend from both sides of the connecting body 210 and respectively enter the first cavity 141 of the two connecting structures 100. Thus, through one exterior wall fixing node 10, two adjacent wall panels 20 in the vertical direction can be simultaneously fixedly connected. Meanwhile, as... Figure 29 As shown, the spacing D4 between adjacent wall panels 20 is greater than the dimension D5 of the end of the connecting body 210 near the wall panel 20, so that the end of the connecting body 210 near the wall panel 20 can extend into the space between adjacent wall panels 20. This can be understood as adjusting the fixing plate 220 according to the spacing between the wall panel 20 and the wall 30. Figure 4 In the state of being in the first cavity 141, the distance between the end of the connecting body 210 near the wall plate 20 and the wall plate 20 will change, and it may even be necessary to extend the end into the space between adjacent wall plates 20. By making the vertical distance between the wall plates 20 greater than the size of the end, the risk of assembly interference between the wall plate 20 and the end can be reduced.

[0131] In some embodiments, such as Figure 30 As shown, in the vertical direction, there is adhesive between two adjacent wall panels 20, and the connecting body 210 extends into the space between the two adjacent wall panels 20 and connects with the adhesive between the two wall panels 20. The connection between the connecting body 210 and the adhesive can improve the structural strength of the exterior wall structure. The part of the connecting body 210 extending into the space between the two wall panels 20 can also provide a certain degree of support for the upper wall panel 20, thereby further improving the strength of the exterior wall structure. Moreover, by squeezing the adhesive with the connecting body 210, the adhesive can fill the space between the two wall panels 20 more fully, which not only makes the fixation between the two wall panels 20 more reliable, but also reduces the amount of adhesive used.

[0132] In some embodiments, such as Figure 31 As shown, Figure 1 The exterior wall structure also includes an infill layer 40, which is close to the wall panel 20. Figure 1The wall 30 is fixedly connected to one side. Depending on the material of the filling layer 40, different functions can be achieved. For example, when the filling layer 40 includes thermal insulation material, the filling layer 40 can improve the thermal insulation capacity of the exterior wall structure. For example, when the filling layer 40 includes sound insulation sponge material, the filling layer 40 can improve the sound insulation capacity of the exterior wall structure. For example, when the filling layer 40 includes mortar and metal mesh, the filling layer 40 can improve the structural strength of the wall panel 20, thereby improving the overall structural strength of the exterior wall structure.

[0133] Optional, such as Figure 32 As shown, the filling layer 40 includes: an adhesive layer 41, an insulation layer 42, and a protective layer 43, extending from the wall panel 20 towards... Figure 1 In the direction of the wall 30, the adhesive layer 41, the insulation layer 42, and the protective layer 43 are arranged sequentially, with the adhesive layer 41 directly fixed to the side of the wall panel 20 closest to the wall 30, thereby fixing the filling layer 40 as a whole to the side of the wall panel 20 closest to the wall 30. The adhesive layer 41 is used to improve the fixing strength between the insulation layer 42 and the wall panel 20. The insulation layer 42 is set as a heat insulation material to improve the heat insulation capacity of the external wall structure. The protective layer 43 is used to cover the insulation layer 42 to protect it. Optionally, the materials of the adhesive layer 41 and the protective layer 43 are mortar, adhesive, or a mixture of mortar and adhesive; alternatively, such as... Figure 32 As shown, the adhesive layer 41 includes mortar 411 and metal mesh 412, with the metal mesh 412 and mortar 411 used to improve the structural strength of the adhesive layer 41.

[0134] In some embodiments, combined with Figure 33 and Figure 34 The external wall fixing node 10 also includes a thermal insulation strip 500. In the horizontal direction, the thermal insulation strip 500 is located on the side of the connecting plate 200; in the vertical direction, the thermal insulation strip 500 is located between adjacent wall panels 20. This means that the connecting plate 200 cannot completely fill the gap between two adjacent connecting plates 200 in the vertical direction, and the thermal insulation strip 500 is needed to seal the gap to improve the thermal insulation capacity of the external wall structure. Optionally, in the horizontal direction, two adjacent external wall fixing nodes 10 each have a thermal insulation strip 500, and the two thermal insulation strips 500 abut against each other, thereby sealing the gap between the two connecting plates 200 through the two thermal insulation strips 500; optionally, in the horizontal direction, two adjacent external wall fixing nodes 10 share one thermal insulation strip 500; optionally, in the vertical direction, the gap between adjacent connecting plates 200 is sealed by... Figure 30 The insulation layer 42 is filled in to improve the insulation capacity of the exterior wall structure.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
