[0016] Furthermore, in this embodiment, the outer surface of the fixing plate has anti-slip texture, and the area of ​​the anti-slip texture covers the adjustment hole.

[0017] Furthermore, in this embodiment, the anti-slip texture includes multiple anti-slip horizontal lines, each of which is spaced apart along the extension direction of the adjustment hole, and the extension direction of each of the anti-slip horizontal lines is perpendicular to the extension direction of the adjustment hole.

[0018] Furthermore, in this embodiment, the anti-slip horizontal stripes include a central stripe and side stripes. The central stripe is located at the center of the adjustment hole in the vertical direction, and the side stripes are symmetrically distributed relative to the central stripe.

[0040] 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.

[0041] 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.

[0043] 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.

[0044] The exterior wall refers 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. Related exterior wall structures require connecting structures to fix the wall panels to the wall body. Different exterior wall structures have different spacing between the wall panels and the wall body, resulting in insufficient versatility of the related connecting structures.

[0045] To address the technical problem that existing wall structures require connection structures to fix wall panels to the wall, and that different exterior wall structures have different spacing between wall panels and the wall, resulting in insufficient versatility of the connection structures, this application provides a directly fixed exterior wall structure. The wall panel assembly is fixedly connected to the wall through fixed nodes. By using fixed nodes with various types of connecting plates, the wall panel assembly can be guaranteed to be flat after being fixedly connected to the wall.

[0046] First, combine Figure 1 The overall result of the exterior wall structure is illustrated by example, such as... Figure 1 As shown, the exterior wall structure includes: a wall 30, a wall panel assembly 20, and fixing nodes 10 for fixing the wall panel assembly 20 to the wall 30. For example, the wall panel assembly 20 is a modular design. During the process of laying the wall panel assembly 20 on the wall 30, several wall panel assemblies are laid layer by layer from bottom to top on the surface of the wall panel 30, and the wall panel assemblies are fixed to the surface of the wall 30 by fixing nodes 10 located between two adjacent wall panel assemblies. The wall panel assembly 20 is a composite wall panel. For example, the composite wall panel includes a wall panel and a connecting frame. By combining the connecting frame with the wall panel, the structural strength of the wall panel can be improved. Furthermore, by fixing the connecting frame to multiple connecting plates to form a fixed exterior wall fixing node, the load borne by the wall panel can be transferred to multiple connecting plates, thereby improving the fixing reliability of the wall panel and the wall. For example, the composite wall panel includes a wall panel and a filling layer. By combining the filling layer with thermal insulation material with the wall panel, the wall panel assembly can have thermal insulation capabilities. The exterior wall structure will be further explained below through various embodiments.

[0047] In some implementations, such as Figure 2 As shown, the fixed node 10 includes a connecting structure 100 and a connecting plate 200. The connecting structure 100 is used to fit against the wall panel assembly 20. The connecting plate 200 includes a fixing plate 51 and an extension wall 52. The fixing plate 51 is directly fixed to the wall panel assembly 20. Figure 1In the wall 30, the extension wall 52 is fixedly connected to the connecting structure 100. The extension wall 52 extends out of the fixing plate 51 along the first direction and is fixedly connected to the connecting structure 100. For example, in the process of laying the wall 30 components on the surface of the wall 30, the installation position of the connecting plate 200 is planned on the surface of the wall 30 according to the size of the wall 30 components. The connecting plate 200 with a suitable size of the extension wall 52 is selected, and the connecting plate 200 is directly fixedly installed on the surface of the wall 30 according to the pre-planned installation position. The wall 30 components are stacked from bottom to top. When the upper wall 30 components are installed on the lower wall 30 components, the connecting structure 100 is connected to the fixing plate 51 of the connecting plate 200 through the extension wall 52 on the connecting plate 200. The connecting structure 100 is placed at the joint between the upper wall 30 and the lower wall 30, and the connecting structure 100 is attached to the two adjacent walls 30, thereby completing the laying of the wall panel components 20.

[0048] Among them, such as Figure 3 As shown, the connecting plate 200 has various types, and the extension wall 52 of each type of connecting plate 200 has different dimensions. By setting various adapter plates with extension walls 52 of different sizes, the fixing node 10 can adapt to walls 30 with different verticality and flatness errors, thereby ensuring the flatness of the wall 30 components after being laid on the surface of the wall 30. This allows the fixing node to adapt to the spacing between wall panels 20 and walls 30 in different exterior wall structures, improving the versatility of the fixing node.

[0049] This utility model provides a schematic diagram of an indirectly fixed exterior wall structure, including: a wall, wall panel assemblies, and fixing nodes for fixing the wall panel assemblies to the wall. The wall panel assemblies are modularly designed. During the installation of the wall panel assemblies on the wall, several wall panel assemblies are laid layer by layer from bottom to top on the surface of the wall panel assembly. The wall panel assemblies are fixed to the wall surface by fixing nodes set between two adjacent wall panel assemblies. When laying the wall panel assemblies on the wall, the installation positions of the connecting plates are planned on the wall surface according to the size of the wall panel assemblies. Connecting plates with appropriate dimensions for the extension wall are selected, and the connecting plates are directly fixed to the wall surface according to the pre-planned installation positions, stacked sequentially from bottom to top. The wall panel assembly is installed by extending the extension wall on the connecting plate to the fixing plate of the connecting plate. The connecting structure is placed at the joint between the upper wall panel assembly and the lower wall and is then fitted to the two adjacent walls to complete the wall panel installation. By setting a fixing node at the joint between the upper and lower adjacent wall panel assemblies, the connection between the wall and the wall panel assembly is strengthened. This prevents issues such as hollow areas between the wall and the wall panel assembly, or cracking and failure of the adhesive mortar due to time, which can lead to unstable installation of the wall panel assembly and subsequent detachment from the building wall surface. This greatly enhances the safety of the wall panel assembly during use.

[0050] In some embodiments, such as Figure 3 As shown, the dimensions of the extension walls 52 of the various types of connecting plates 200 form an arithmetic sequence, for example, Figure 3 The diagram shows three types of connecting plates 200, with the extension walls 52 of the three types of connecting plates 200 having lengths of D1, D2, and D3, respectively. The dimensions of D1, D2, and D3 are 15 mm, 20 mm, and 25 mm, respectively. During use, the dimensions of the extension walls 52 form an arithmetic sequence of adapter plates, allowing users to quickly match the required specifications through simple calculations, achieving standardization, scalability, and easy management.

[0051] In some embodiments, such as Figure 4As shown, the fixing plate 51 has a fixing hole 53 and an adjusting hole 54. In the vertical direction, the fixing hole 53 and the adjusting hole 54 are arranged at intervals. The fixing hole 53 is a round hole, and the adjusting hole 54 is an elongated hole that extends in the vertical direction. For example, the fixing plate 51 can be fixed to the wall 30 by bolts 55. Before fixing the fixing plate 51 to the wall 30, holes are drilled at the pre-planned installation position to form mounting holes for fixing the bolts 55 in the wall 30. When fixing the fixing plate 51 to the wall 30, the fixing plate 51 is placed at the pre-planned installation position, and the two bolts 55 pass through the fixing hole 53 and the adjusting hole 54 respectively through the fixing plate 51 to fix the fixing plate 51 to the wall 30. However, in order to facilitate the installation of the fixing plate 51, the mounting holes are pre-drilled before the fixing plate 51 is installed. Therefore, when the bolts 55 pass through the fixing plate 51 and connect to the wall 30, the pre-drilled mounting holes may not be aligned with the fixing hole 53 and the adjusting hole 54 at the same time due to errors. In this embodiment, the adjusting hole 54 is set as an elongated hole. The position of the bolts 55 passing through the fixing plate 51 can be adjusted through the elongated adjusting hole 54 so that the fixing plate 51 can be connected to the wall 30 by the bolts 55.

[0052] It should be noted that after the two fixing bolts are fixedly connected through the adjusting hole 54 and the fixing hole 53 respectively, for ease of explanation, the two bolts will be referred to as the first bolt and the second bolt respectively. The first bolt 54 is a tension bolt, mainly used to bear the bending moment transmitted from the wall panel 20 to the wall 30. The fixing hole 53 forms a hinge hole. The second bolt fits against the inner wall of the fixing hole 53, thus making the second bolt a shear bolt. The second bolt is mainly used to bear the shear force transmitted from the wall panel 20 to the wall 30. That is, by using two kinds of bolts to bear the bending moment and shear force respectively, the fixing reliability of the wall panel 20 and the wall 30 is improved.

[0053] In some embodiments, such as Figure 4 As shown, the adjustment hole 54 is located above the fixing hole 53. During use, setting the adjustment hole 54 above the fixing hole 53 can reduce the obstruction of the adjustment hole 54 by the extension wall 52, making visual alignment more convenient.

[0054] In some embodiments, such as Figure 4 As shown, the distance between the top of the fixing plate 51 and the extension wall 52 is greater than the distance between the bottom of the fixing plate 51 and the extension wall 52. The fixing hole 53 and the adjustment hole 54 are both located above the extension wall 52. It can be understood that in this embodiment, the extension wall 52 is set at a position other than the end of the fixing plate 51 to form a "T" shaped structure. This structure has good anti-overturning ability, thereby increasing the stability of the connecting plate 200 under stress.

[0055] In some embodiments, such as Figure 4As shown, both the fixing hole 53 and the adjusting hole 54 are located above the extension wall 52, which can effectively increase the effective load of the connecting plate 200. It can be understood that in this embodiment, the connection between the extension wall 52 and the fixing plate 51 can be regarded as a fulcrum, and the fixing plate 51 below the extension wall 52 can be regarded as a power arm. The distance from the connection between the extension wall 52 and the fixing plate 51 to the fixing hole 53 and the adjusting hole 54 can be regarded as an assisting arm. Therefore, according to the lever principle, in this embodiment, the fixing hole 53 and the adjusting hole 54 are both located above the extension wall 52, thereby increasing the distance of the resistance arm, so that the load on the bolts set at the fixing hole 53 and the adjusting hole 54 is reduced, thereby increasing the effective load of the connecting plate 200.

[0056] In some embodiments, such as Figure 4 As shown, the outer surface of the fixing plate 51 has anti-slip texture 60, and the area of ​​the anti-slip texture 60 covers the adjustment hole 54. That is, the adjustment hole 54 is located in the area where the anti-slip texture 60 is located. When the fixing bolt is inserted into the adjustment hole 54, the nut of the fixing bolt can fit against the anti-slip texture 60, thereby increasing the friction between the bolt 55 and the fixing plate 51 through the anti-slip texture, and thus increasing the stability of the connecting plate 200 when it is fixed to the wall 30. It should be noted that the anti-slip texture 60 can be of any shape. For example, the anti-slip texture can be a dot array, a line array, or a mesh array. The anti-slip texture can be formed in any way. For example, the anti-slip texture can be formed by setting a protrusion on the surface of the fixing plate 51 near the adjustment hole 54, or the anti-slip texture can be formed by setting a depression on the surface of the fixing plate 51 near the adjustment hole 54.

[0057] In some embodiments, such as Figure 5 As shown, the anti-slip texture 60 includes multiple anti-slip horizontal lines 61. Each anti-slip horizontal line 61 is spaced apart along the extension direction of the adjustment hole 54, and the extension direction of each anti-slip horizontal line 61 is perpendicular to the extension direction of the adjustment hole 54. It can be understood that in this embodiment, the anti-slip horizontal lines intersect the axis of the bolt 55 at 90°, forming an interlaced friction surface, which can increase the friction force on the bolt 55 when the fixing plate 51 is fixed to the wall 30 by the bolt 55, and further increase the stability of the connecting plate 200 when it is fixed to the wall 30.

[0058] In some embodiments, such as Figure 5 As shown, the anti-slip horizontal stripes 61 include a central stripe 611 and side stripes 612. The central stripe 611 is located at the center of the adjustment hole 54 in the vertical direction, and the side stripes 612 are symmetrically distributed relative to the central stripe 611. The central stripe 611 allows the user to quickly determine the center position of the adjustment hole 54, which facilitates the positioning of the connecting plate 200 during the installation process, thereby facilitating the installation of the connecting plate 200.

[0059] In some embodiments, such as Figure 5 As shown, the distance between the side stripe 612 adjacent to the central stripe 611 and the central stripe 611 is the first distance, and the distance between two adjacent side stripes 612 is the second distance. The first distance and the second distance are different. By adjusting the interval between the central stripe 611 and the adjacent side stripe 612 and the two side stripes 612, the distribution of anti-slip horizontal stripes on the fixing plate 51 becomes different, thereby enabling the user to more quickly determine the center position of the adjustment hole 54.

[0060] In some embodiments, such as Figure 6 As shown, the connecting plate 200 also includes marking protrusions 210, which protrude from the outer surface of the extension wall 52. The number of marking protrusions 210 is positively correlated with the size of the extension wall 52. The size of the extension wall 52 of the connecting plate 200 can be quickly identified by the marking protrusions 210, so that the user can select the connecting plate 200 of the required specifications.

[0061] In some embodiments, such as Figure 6 As shown, the marking protrusion 210 protrudes less than 0.5 mm from the extension wall 52, ensuring its clear visibility while preventing it from interfering with the connection between the extension wall 52 and the connecting structure 100. It should be noted that the surface of the fixing plate 51 has a part number for the connecting plate 200, which allows the length of the extension wall 52 to be determined. The marking protrusion 210 assists the operator in confirming the length of the extension wall 52, thus eliminating the need to set its protrusion size to a large dimension.

[0062] In some embodiments, such as Figure 1 As shown, the wall panel assembly 20 includes a wall panel 21, a filling layer 22, and positioning screws 23. The filling layer 22 is fixed to the side of the wall panel 21 near the wall 30. The extension wall 52 is connected to the filling layer 22 by the positioning screws 23, so that the connecting plate 200 can be connected to the wall panel assembly 20 by the positioning screws 23. It can be understood that the filling layer 22 can be set on the surface of the wall 30 as a functional wall to enhance the practicality of the wall panel assembly 20. For example, different functions can be achieved according to the material of the filling layer 22, such as thermal insulation material, waterproof material, or sound insulation material, so that the filling layer 22 can achieve functions such as thermal insulation, waterproofing and moisture-proofing, or sound insulation and noise reduction. Therefore, in this embodiment, the filling layer 22 made of different functional materials can be selected according to actual needs to increase the practicality of the wall panel assembly 20 laid on the surface of the wall 30.

[0063] Secondly, in this embodiment, the wall panel 21 is disposed on the side of the filling layer 22 away from the wall 30, which not only serves a decorative purpose but also protects the filling layer 22. For example, in this embodiment, in addition to the above functions, the wall panel 21 can also achieve different functions depending on the material used, such as thermal insulation material, waterproof material, or sound insulation material, thereby enabling the wall panel 21 to achieve functions such as thermal insulation, waterproofing, moisture resistance, or sound insulation.

[0064] In some embodiments, as shown in the figure, the extension wall 52 has a positioning hole 521, and the head of the positioning screw 23 is accommodated in the positioning hole 521. It is understood that after the positioning screw 23 passes through the extension wall and is connected to the wall assembly 30, the head of the positioning screw 23 is accommodated in the positioning hole 521, that is, the head of the positioning screw 23 does not protrude or only partially protrudes from the extension wall. This can prevent the head of the positioning screw 23 from contacting the bottom of the upper wall 30 when the upper wall 30 is connected to the lower wall 30, so that a gap is formed between the upper wall 30 and the extension wall, which would affect the stability of the wall panel assembly 20 when it is laid on the surface of the wall 30. It should be noted that the positioning bolt 23 is mainly used to provide pre-positioning for the wall panel when installing the wall panel assembly 20. Specifically, when fixing the fixing node 10 to the wall panel assembly 20 located below the fixing node, the positioning bolt 23 is used to fix the connecting plate in the fixing node 10 to the filling layer 22 in the wall panel assembly 20 located below, thereby restricting the displacement of the fixing node 10 when installing the wall panel assembly 20 above, thus facilitating the installation of the wall panel assembly 20.

[0065] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
