Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0031] like Figures 1 to 8 As shown, this is an embodiment of the leveling keel system for installing wall panels according to the present invention. In this embodiment, the leveling keel system is disposed between the wall panel 1 and the wall 2 to connect the wall panel 1 and the wall 2.

[0032] See Figure 1 , Figure 2 and Figure 3 , the leveling keel system for installing the wall panel in this embodiment includes a leveling keel 3, a leveling bolt assembly 4 and a connecting piece 5.

[0033] Among them, the leveling keel 3 has a "U" - shaped structure. The leveling keel 3 has good stability and bearing capacity, and can effectively support the weight of the wall panel 1. The leveling keel 3 includes a leveling part 31, a bending part 32 and a flanging part 33. The flanging part 33 is connected to the leveling part 31 through the bending part 32. Bending parts 32 and flanging parts 33 are provided on both sides of the leveling part 31. The leveling part 31 is the main planar part of the leveling keel 3, which is used to connect with the leveling bolt assembly 4 and provides a flat installation reference surface. The bending part 32 connects the leveling part 31 and the flanging part 33, playing a role in transition and enhancing the structural stability. The flanging part 33 increases the lateral support capacity of the leveling keel 3, preventing the wall panel 1 from shaking and displacing after being installed on the leveling keel 3.

[0034] One end of the leveling bolt assembly 4 is thread - connected to the wall body 2, and the other end of the leveling bolt assembly 4 is connected to the leveling part 31. The leveling bolt assembly 4 is fixed to the wall body 2 through thread connection. By using the self - locking property and adjustability of the thread, the support and leveling of the leveling keel 3 are realized.

[0035] The connecting piece 5 is used to cooperate with the bending part 32 and the flanging part 33. The wall panel 1 is connected to the leveling keel 3 through the connecting piece 5. The connecting piece 5 can adapt to various installation processes between the bending part 32 and the flanging part 33, such as dry - hanging, dry - sticking, screw fixing, etc., so that the leveling keel system can meet different building scenarios and construction requirements, and has wide applicability.

[0036] Thus, for the leveling keel system for installing the wall panel in this embodiment, the leveling keel 3 is connected to the wall body 2 through the leveling bolt assembly 4, and the leveling function is realized by using the self - locking property and adjustability of the thread. The leveling part 31 provides a flat installation reference surface for the wall panel 1. The connecting piece 5 cooperates with the bending part 32 and the flanging part 33, adapting to various installation processes such as dry - hanging, dry - sticking, screw fixing, etc., to achieve the stable connection between the wall panel 1 and the leveling keel 3. This design not only improves the installation efficiency and quality, but also enhances the stability and reliability of the system, reduces the construction cost, meets different building scenarios and construction requirements, and has wide applicability.

[0037] See Figure 3Preferably, the leveling bolt assembly 4 includes a nut 41, a screw 42, and an expansion member 43. The expansion member 43 is disposed in the wall 2. One end of the screw 42 is threadedly connected to the expansion member 43, and the other end of the screw 42 passes through the leveling part 31 and is locked by the nut 41. The expansion member 43 is tightly fixed in the pre-drilled hole in the wall 2 by the principle of expansion, providing a stable support point and ensuring the firmness of the leveling bolt assembly 4. The nut 41 is threadedly connected to the screw 42 and clamps and fixes the leveling part 31, ensuring a firm connection between the leveling keel 3 and the screw 42. The expansion member 43 has an internal thread, and the screw 42 has an external thread. The expansion member 43 and the screw 42 achieve threaded engagement through the internal and external threads. By rotating the screw 42, the screw 42 drives the leveling keel 3 to move along the axial direction of the screw 42, thereby adjusting the distance between the leveling keel 3 and the wall 2 and precisely controlling the final flatness of the wall panel 1.

[0038] See Figure 2 Preferably, the leveling part 31 has an oblong hole 311, and one end of the screw 42 connected to the leveling part 31 passes through the oblong hole 311. The oblong hole 311 allows the screw 42 to move along the length of the oblong hole 311 within a certain range, providing a fine-tuning function, thereby further improving the leveling accuracy, ensuring that the wall panel 1 is installed on a flat reference surface, and enhancing the stability and adaptability of the system.

[0039] See Figure 1 and Figure 2 Preferably, the flanged portion 33 includes a first flanged portion 33a and a second flanged portion 33b, which are respectively located on both sides of the leveling portion 31 and have different flanged lengths. The first flanged portion 33a and the second flanged portion 33b provide different flanged lengths, forming an asymmetrical design. This allows the leveling keel 3 to adapt to various installation processes, reducing the types of special accessories and lowering construction costs. In this embodiment, the flanged length of the first flanged portion 33a is 3mm, and the flanged length of the second flanged portion 33b is 5mm.

[0040] See Figure 3In the first embodiment of this invention, preferably, the connector 5 is a dry-hanging component 5a. The dry-hanging component 5a includes a connecting plate 5a1 and a snap-fit ​​plate 5a2. The connecting plate 5a1 is used for fixed connection with the wall panel 1. The snap-fit ​​plate 5a2 is bent from the connecting plate 5a1 toward the wall 2 to form a snap-fit ​​groove 5a3 with a vertical downward opening. The bent portion 32 and the flange portion 33 on one side of the leveling keel 3 are snapped into the snap-fit ​​groove 5a3. The connecting plate 5a1 is fixedly connected to the wall panel 1 by screws to ensure a firm connection between the wall panel 1 and the dry-hanging component 5a, preventing the wall panel 1 from loosening during installation. In this embodiment, when connecting the wall panel 1 and the leveling keel 3 through the dry-hanging component 5a, the side where the second flange portion 33b of the leveling keel 3 is located is arranged facing upwards, and the leveling keel 3 is locked and fixed by the nut 41. When installing wall panel 1, place the dry-hanging fitting 5a connected to wall panel 1 above the leveling keel 3, and align the vertically downward-opening snap-fit ​​groove 5a3 with the second flange 33b and the bent part 32 of the leveling keel 3. Finally, move wall panel 1 downward so that the second flange 33b and the bent part 32 snap into the snap-fit ​​groove 5a3, thereby achieving rapid installation of wall panel 1. By snapping the dry-hanging fitting 5a3 into the leveling keel 3, the adjustment time during installation is reduced, significantly improving installation efficiency and reducing construction time and labor costs.

[0041] See Figure 4 , Figure 5 and Figure 6 Preferably, the fixed connection points between the connecting plate 5a1 and the wall panel 1 are distributed on the upper and lower sides of the leveling keel 3. In this embodiment, a preferred design PZ-D5 dry-hanging component 5a is used. The connecting plate 5a1 of the PZ-D5 dry-hanging component 5a has a certain extension length, and the extension length of the connecting plate 5a1 is not less than the width of the leveling keel 3 from the first flange 33a to the second flange 33b. When the leveling keel 3 is engaged in the engaging groove 5a3, the two sides of the connecting plate 5a1 in the length direction are located on the upper and lower sides of the leveling keel 3, respectively. Furthermore, connecting holes 5a4 are provided on both sides of the connecting plate 5a1 along its length. Screws pass through the connecting holes 5a4 to fix the connecting plate 5a1 to the wall panel 1. Thus, the fixed connection points between the connecting plate 5a1 and the wall panel 1 are distributed on the upper and lower sides of the leveling keel 3, avoiding the disadvantage that the dry-hanging part 5a fixed by screws on one side is easily pulled out when the interlocking point with the leveling keel 3 is subjected to overturning moment.

[0042] See Figure 7In the second embodiment of this invention, preferably, the connector 5 is structural adhesive 5b, which is applied between the bending portion 32 and the wall panel 1 to bond the leveling keel 3 and the wall panel 1. During installation, structural adhesive 5b is applied to the opposing sides of the bending portion 32 of the leveling keel 3 and the wall panel 1, and then the wall panel 1 is attached to the bending portion 32 to achieve initial bonding. Then, one end of the leveling device 6 with a tie groove 61 passes through the wall panel 1, and the leveling device 6 is engaged and locked with the first flange portion 33a of the leveling keel 3 through the tie groove 61. Moving the leveling device 6 away from the leveling keel 3 causes the leveling keel 3 to be pressed against the wall panel 1, thereby enhancing the bonding effect of the structural adhesive 5b and ensuring a firm bond between the wall panel 1 and the leveling keel 3.

[0043] See Figure 2 Preferably, the bent portion 32 has perforations 321, through which structural adhesive 5b is extruded onto the side of the bent portion 32 facing the wall 2. After being extruded from the perforations 321, the structural adhesive 5b is distributed on both sides of the bent portion 32, forming a mushroom-shaped structure. This increases the bonding area between the structural adhesive 5b and the wall panel 1 and the bent portion 32, enhancing the strength and reliability of the bond.

[0044] See Figure 8 In the third embodiment of this invention, preferably, the connector 5 is a screw 5c. The head of the screw 5c is connected to the wall panel 1 and protrudes from the side of the wall panel 1. The bent portion 32 is recessed towards the wall panel 1 to form a countersunk groove 322. The shank of the screw 5c passes through the bent portion 32 and the head of the screw 5c is accommodated in the countersunk groove 322. During connection, the head of the screw 5c is accommodated in the countersunk groove 322, which avoids interference between the head of the screw 5c and the connection between the wall panel 1 and the leveling keel 3, and also keeps the wall panel 1 and the leveling portion 31 of the leveling keel 3 parallel, ensuring the flat installation of the wall panel 1.

[0045] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
