[0041] Please refer to Figure 1 to Figure 3 The utility model provides a hidden external corner mounting structure of wallboard, through corresponding installation of first mounting column 21, second mounting column 22, a plurality of first connecting pieces 31 and a plurality of second connecting pieces 32 on first wallboard 11 and second wallboard 12 respectively and connection of external corner connecting furring 4 and external corner wall body, a stable support structure is formed and covers the external corner wallboard of wall body. Figure 1 The first mounting column 21 is mounted on the wall side of the first wallboard 11 (as shown in the left side of Figure 1 The second mounting column 22 is mounted on the wall side of the second wallboard 12 (as shown in the rear side of The first mounting column 21 and the second mounting column 22 are connected with the external corner trim 5, the first wallboard 11 and the second wallboard 12 are limited to be perpendicular to each other through the external corner trim 5, and are decorated through the external corner trim 5, so that the external corner treatment is more smooth and beautiful, and the overall decoration effect is improved.

[0042] The external corner mounting structure is combined with the mounting columns (the first mounting column 21 and the second mounting column 22) and the connecting pieces (the first connecting piece 31 and the second connecting piece 32), the wainscot (the first wainscot 11 and the second wainscot 12) is quickly and conveniently mounted at the external corner, without needing to process complex embedding grooves at the edges of the wainscot, the installation process is greatly simplified, and the construction efficiency is improved. Without needing to specially process the wainscot (such as embedding grooves), the mounting structure is suitable for various types and materials of the wainscot, the versatility and applicability of the wainscot are improved. In addition, the structure is convenient for subsequent maintenance and replacement work.

[0043] Further, the external corner molding strip 5 comprises a rectangular splicing part and a wainscot clamping part;

[0044] The rectangular splicing part comprises a first plate 511, a second plate 512, a third plate 513 and a fourth plate 514 connected in head-tail mode, the first plate 511 and the third plate 513 are parallel to each other, the second plate 512 and the fourth plate 514 are parallel to each other, and the second plate 512 is perpendicular to the first plate 511; the wainscot clamping part comprises a first clamping plate 521 and a second clamping plate 522, the first clamping plate 521 is an extension of the first plate 511, the second clamping plate 522 is an extension of the fourth plate 514, and the first clamping plate 521 is perpendicular to the second clamping plate 522;

[0045] One side of the first wainscot 11 is clamped in a right-angle groove formed by the fourth plate 514 and the first clamping plate 521, and one side of the second wainscot 12 is clamped in a right-angle groove formed by the first plate 511 and the second clamping plate 522.

[0046] By designing the external corner molding strip 5 to comprise a rectangular splicing part and a wainscot clamping part, the first wainscot 11 and the second wainscot 12 can be clamped in the right-angle grooves formed by the external corner molding strip 5 respectively. This design not only simplifies the installation process, but also enhances the stability of the wainscot at the external corner through physical clamping, and reduces loosening or deformation caused by improper installation or external force.

[0047] The quadrilateral design of the rectangular splicing part and the right-angle extension of the wainscot clamping part make the external corner molding strip 5 visually present more simple and smooth lines. At the same time, the accurate alignment structure is provided for the wainscot provided with the mounting column, which helps the wainscot to be accurately and closely arranged in the two mutually perpendicular right-angle grooves composed of the rectangular splicing part and the wainscot clamping part during installation.

[0048] Further, the first mounting column 21 and the second mounting column 22 are rectangular mounting columns of the same structure, the first wall panel 11 and the second wall panel 12 are wall panels of the same structure, and the first connecting piece 31 and the second connecting piece 32 are connecting pieces of the same structure.

[0049] The rectangular mounting column is composed of a first column plate 201, a second column plate 202, a third column plate 203, and a fourth column plate. The first column plate 201 is connected with the wall panel, the second column plate 202 is connected with the external corner trim 5, the third column plate 203 is connected with the connecting piece, and the first column plate 201 and the third column plate 203 are parallel to each other, and the second column plate 202 and the fourth column plate are parallel to each other.

[0050] By designing the first mounting column 21 and the second mounting column 22 as rectangular mounting columns of the same structure, the first wall panel 11 and the second wall panel 12 as wall panels of the same structure, and the first connecting piece 31 and the second connecting piece 32 as connecting pieces of the same structure, the design and production process of the product are greatly simplified. This unified and standardized design helps to reduce production costs and improve production efficiency. In addition, since the rectangular mounting column, the wall panel, and the connecting piece are of the same structure, these components can be replaced and combined with each other during actual installation. This interchangeability not only improves the flexibility of construction, but also facilitates subsequent maintenance and replacement work. When a component is damaged or needs to be upgraded, it can be directly replaced with a component of the same type without the need to make significant adjustments to the entire installation structure.

[0051] The design of the rectangular mounting column enables the formation of a stable support structure between its various plates. The first column plate 201 is connected with the wall panel, the second column plate 202 is connected with the external corner trim 5, and the third column plate 203 is connected with the connecting piece. This layout enables the mounting column to remain stable when bearing the weight and pressure from the wall panel. At the same time, the parallel and perpendicular relationship between the plates helps to enhance the stability and durability of the overall structure.

[0052] Further, the connecting piece includes a main body 301 and a connecting portion 302. One side of the main body 301 is connected with the third column plate 203, and the connecting portion 302 is located on the side of the main body 301 away from the rectangular mounting column, and the connecting portion 302 is connected with the external corner connecting furring 4.

[0053] The connecting portion 302 of the first connecting piece and the connecting portion 302 of the second connecting piece are perpendicular to each other.

[0054] By separating the connecting piece into the main body 301 and the connecting part 302, the connecting piece is more stable in structure. The main body 301 is connected to the third column plate 203 of the rectangular mounting column, while the connecting part 302 is responsible for connecting with the external corner connecting keel 4. This separation design makes each part focus on its specific function, thereby improving the overall connection stability. Preferably, the main body 301 is mounted and connected with the rectangular mounting column through fasteners. The connecting part 302 of the first connecting piece and the connecting part 302 of the second connecting piece are perpendicular to each other, which helps to ensure that the first and second wainscot panels 11 and 12 can be accurately aligned and connected at the external corner during installation. This perpendicular relationship provides a clear reference for the construction personnel, which helps to reduce installation errors and improve installation accuracy.

[0055] This design of the connecting piece makes the installation process more intuitive and simple. The construction personnel only need to fix the main body 301 on the rectangular mounting column, and then connect the connecting part 302 with the external corner connecting keel 4. In addition, since the perpendicular relationship between the connecting parts 302 is already pre-set, there is no need for complex adjustment during installation.

[0056] It is worth noting that, Figure 4 The number of the first connecting pieces 31 and the second connecting pieces 32 shown in the figure is not a limitation of the number of the connecting pieces of the present application. A plurality of first connecting pieces 31 and a plurality of second connecting pieces 32 are arranged at intervals along the height direction of the first mounting column 21 and the second mounting column 22, and the number and position of the connecting pieces can be flexibly adjusted according to the size of the wall and the specifications of the wainscot panels.

[0057] Further, the connecting piece further comprises an inclined part 303, which is arranged inclined from the connecting part 302 to the direction of the main body 301, and the inclined part 303 is inclined at an angle of 45°.

[0058] The inclined part 303 of the first connecting piece and the inclined part 303 of the second connecting piece abut each other.

[0059] The design of the inclined part 303 provides an additional support point between the first connecting piece and the second connecting piece. When the inclined parts 303 of the first connecting piece and the second connecting piece abut each other, they form a stable structure, which helps to enhance the overall stability of the external corner mounting structure and reduce deformation or loosening caused by external forces. The 45° inclination design of the inclined part 303 helps to optimize the stress distribution between the connecting pieces on the one hand, and on the other hand, the inclined parts 303 of the two connecting pieces are spliced together to form a stable square structure, making the connection between the two wainscot panels of the external corner mounting structure of the present application and the connection between the wainscot panels and the external corner wall body more stable and compact.

[0060] Although the design of the inclined part 303 increases the complexity of the connecting piece, it also simplifies some steps in the installation process. Since the mutual abutment of the inclined parts 303 can automatically correct the position and angle of the cladding, the construction personnel do not need to make excessive adjustments to achieve accurate installation. This design improves installation efficiency and reduces construction difficulty.

[0061] Further, the external corner connecting rail 4 comprises a column body 401, a first mounting part 402 and a second mounting part 403. The column body 401 extends in the height direction. The first mounting part 402 and the second mounting part 403 are arranged perpendicularly to each other on the column body 401. The first mounting part 402 is detachably connected with the connecting part 302 of the first connecting piece. The second mounting part 403 is detachably connected with the connecting part 302 of the second connecting piece. The side of the column body 401 away from the first mounting part 402 and the second mounting part 403 is connected with the external corner wall body.

[0062] The column body 401, as the main load-bearing part of the external corner connecting rail 4, is arranged to extend in the height direction, which helps to optimize the stress distribution of the entire installation structure. When the cladding is subjected to external forces, the column body 401 can effectively disperse and bear these forces, thereby protecting the cladding and connecting pieces from damage. The perpendicular arrangement of the first mounting part 402 and the second mounting part 403 allows them to be accurately connected with the first connecting piece and the second connecting piece respectively, thereby ensuring that the cladding can be stably and accurately installed at the external corner. At the same time, this detachable connection method also facilitates subsequent maintenance and replacement work.

[0063] The close connection of the first mounting part 402 and the second mounting part 403 with the connecting pieces, as well as the stable connection of the column body 401 with the external corner wall body, together form a stable installation structure. This design enhances the overall stability of the external corner installation structure, reducing the safety hazards caused by looseness or deformation.

[0064] Further, the adjustment mounting piece 6 is also included. The adjustment mounting piece 6 comprises a wall body mounting block 61 and an adjustment piece 62. The wall body mounting block 61 is connected with the external corner wall body. One end of the adjustment piece 62 is connected with the external corner connecting rail 4, and the other end of the adjustment piece 62 is adjustably connected with the wall body mounting block 61.

[0065] In actual installation process, due to the unevenness, size deviation or special design requirements of the wall body, directly installing the external corner connecting rail 4 may encounter difficulties or result in poor installation effect. The introduction of the adjustment mounting piece 6 allows for fine-tuning during installation according to the actual situation of the wall body, thereby ensuring that the external corner connecting rail 4 can be accurately and stably installed at the predetermined position, improving the adaptability and flexibility of installation.

[0066] The distance between the corner connecting batten 4 and the corner wall can be precisely adjusted by the adjusting member 62, so that the cladding panel can present a perfect visual effect after installation. In particular, when the cladding panel needs to be closely attached to the wall or needs to leave a certain gap to meet the design requirements, the adjusting installation member 6 can provide a reliable solution. Although the introduction of the adjusting installation member 6 increases the complexity of installation, it also simplifies the installation steps in some cases. For example, when the wall has obvious unevenness, the traditional installation method may require additional filling or trimming work. However, using the adjusting installation member 6, the unevenness of the wall can be directly compensated by the adjusting member 62, saving additional filling or trimming work.

[0067] Further, the wall mounting block 61 is in a "convex" shape, and the wall mounting block 61 includes a first support plate 611, a bent connecting plate 612, and a second support plate, the first support plate 611 and the second support plate are respectively arranged on both sides of the bent connecting plate 612, the first support plate 611 and the second support plate are used to be connected with the corner wall, and the bent connecting plate 612 is provided with a threaded hole.

[0068] The adjusting member 62 includes a sliding block nut 621 and a screw rod 622, the column body 401 is provided with a sliding groove 404, the sliding groove 404 extends along the length direction of the column body 401 and penetrates through both ends of the column body 401, the sliding block nut 621 is in sliding connection with the sliding groove 404 in cooperation, and the screw rod 622 is in connection with the threaded hole of the bent connecting plate 612 in cooperation.

[0069] The "convex" shape design of the wall mounting block 61 provides a larger installation contact area, so that the first support plate 611 and the second support plate can be more firmly connected with the corner wall. Preferably, the first support plate 611 and the second support plate are connected with the corner wall through self-tapping screws, which enhances the connection strength between the wall mounting block 61 and the corner wall, thereby improving the stability of the entire installation structure.

[0070] One end of the adjusting member 62 is a sliding block nut 621, which is slidably connected along the upper and lower through-slots 404 of the external corner connecting batten 4; the other end of the adjusting member 62 is a screw rod 622, which is threadedly connected with the wall body mounting block 61, and the distance between the external corner connecting batten 4 and the external corner wall body can be adjusted by rotating the screw rod 622 to screw it into or out of the threaded hole. Specifically, during installation, the wall body mounting block 61 is mounted and connected with the external corner wall body, the sliding block nut 621 of the adjusting member 62 is slid into the sliding slot 404 of the external corner connecting batten, and after the installation of the adjusting member 62 and the wall body mounting block 61 is completed, the screw rod 622 is aligned with the threaded hole of the bent connecting plate 612 of the wall body mounting block 61, the screw rod 622 is screwed into the threaded hole, and the distance between the external corner connecting batten 4 and the external corner wall body is adjusted by rotating the screw rod 622.

[0071] Further, as shown in Figure 2 The column body 401 is also provided with a pull rivet nut parallel to the adjusting member 62, which is used to cooperate with the adjusting and mounting member 6 to adjust the activity; specifically, during the cooperation of the adjusting member 62 and the wall body mounting block 61 to mount the external corner connecting batten 4 and the wall body, the pull rivet nut corrects the adjusting and mounting member 6, so as to avoid the non-parallel installation of the wainscot caused by the non-parallel connection of the external corner connecting batten 4 and the wall body.
