[0002] In the field of architectural decoration, dry-hanging fasteners for decorative panels are the core components for achieving a reliable connection between decorative panels such as stone, ceramic panels, and aluminum panels and the main building structure. Their performance directly affects the installation efficiency, connection stability, and overall appearance of the decorative panels, and they have been widely used in interior and exterior facade decoration projects of various buildings.

[0003] Existing dry-hanging fasteners for decorative panels have significant limitations in practical applications: Firstly, most fasteners lack a flexible adjustment structure for connection with the horizontal keel, and can only be installed through precise pre-positioning. If the construction layout deviates or the wall base is uneven, the components need to be removed and readjusted, which is cumbersome. Secondly, the connection between the panel and the fastener mostly relies on a single bolt tightening or simple snap-fit, which either involves a complex and time-consuming assembly process or excessive gaps, resulting in insufficient connection stability and making it difficult to balance installation efficiency and connection reliability.

[0004] On the other hand, during the installation of multi-layer decorative panels, there is a lack of dedicated collaborative connection structures between adjacent panels, and they mostly rely on indirect support from horizontal keels, resulting in poor overall integrity of the entire decorative panel system. The load of a single panel is easily concentrated at a local fixed point or keel section, and under long-term stress from gravity, wind, and other loads, the panel is prone to displacement and deformation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 2 , Figure 4 This utility model provides an embodiment of a decorative panel dry-hanging fastener, including a wall 1, a decorative panel 2, and a horizontal keel 3. The horizontal keel 3 is U-shaped with an opening facing forward and is made of aluminum alloy or galvanized steel, both of which have good strength and corrosion resistance. Aluminum alloy is suitable for indoor walls, while galvanized steel is more suitable for outdoor walls. The upper and lower surfaces of its left and right ends are fixedly connected to the front surface of the wall 1 by symmetrically arranged L-shaped connecting brackets 4. The horizontal keel 3 provides a horizontal support frame for the decorative panel 2 and is distributed at different heights on the front surface of the wall 1 to form a multi-layer support structure.

[0019] Reference Figure 1 , Figure 2 , Figure 4, the vertical section of the L-shaped connecting corner bracket 4 is connected to the front surface of the wall 1 by bolts, the vertical section fits against the wall 1, and is fastened to the wall 1 by chemical anchor bolts or expansion bolts to ensure the pull-out resistance of the connection. Its horizontal section is respectively connected to the upper and lower surfaces of the transverse keel 3 by bolts, the horizontal section fits with the upper and lower surfaces of the transverse keel 3, and is connected by high-strength bolts to transfer the load of the transverse keel 3 to the wall 1 while ensuring the levelness of the transverse keel 3. The surface of the transverse keel 3 is slidably connected with a fixing block 8 via a sliding assembly. The fixing block 8 is an adapter member between the decorative panel 2 and the transverse keel 3, and its position can be adjusted under the action of the sliding assembly to adapt to the installation requirements of the decorative panel 2.

[0020] With reference to Figure 1 , Figure 2 , Figure 4 , the sliding assembly comprises a sliding chute 5 and a connecting block 7. The sliding chute 5 is formed on the upper and lower surfaces of the transverse keel 3, and the upper and lower surfaces of the transverse keel 3 are both slidably connected with a sliding block 6 adapted to the sliding chute 5. The bottom surface of the sliding block 6 is embedded in the sliding chute 5 to form a sliding fit with the sliding chute 5, which restricts the displacement of the sliding block 6 in the direction perpendicular to the length of the transverse keel 3 and only allows horizontal sliding. The front end of the sliding block 6 is fixedly connected with the upper and lower ends of the rear surface of the connecting block 7 respectively. The bottom of the fixing block 8 is fixedly connected with the upper surface of the upper sliding block 8, and the fixing block 8 is connected with the sliding block 6 through its bottom, sliding along the sliding chute 5 with the sliding block 6 to realize position adjustment.

[0021] With reference to Figure 2 , Figure 4 , the connecting block 7 is in a shape of a "几" with the middle section protruding rearward, and the protruding section is adapted to the inner wall of the transverse keel 3. The protruding section of the "几" shape is embedded into the U-shaped inner cavity of the transverse keel 3 and fits against the inner wall of the transverse keel 3, so as to enhance the connection stability between the sliding block 6 and the transverse keel 3, prevent the fixing block 8 from shaking or shifting during the sliding process with the sliding block 6, and disperse the load transferred by the sliding block 6 at the same time.

[0022] With reference to Figure 1 , Figure 3 , Figure 4 , the rear surface of the decorative panel 2 is snap-connected with the fixing block 8 through a snap-fit assembly. The snap-fit assembly comprises a T-shaped block 10, and the T-shaped block 10 is connected to the rear surface of the decorative panel 2 through a countersunk bolt. The countersunk bolt can ensure the flatness of the rear surface of the T-shaped block 10, avoid the problems of difficult snapping, excessive fit clearance or insecure snap connection caused by the protrusion of the bolt head, and is a key member for realizing the snap connection between the decorative panel 2 and the fixing block 8.

[0023] With reference to Figure 1 , Figure 3 , Figure 4A T-shaped groove 9 is opened on the upper surface of the fixing block 8, and the front side of the T-shaped groove 9 penetrates through the front surface of the fixing block 8. The front penetration facilitates the insertion of the T-shaped block 10, realizing the quick snap-fit assembly of the decorative panel 2 and the fixing block 8. The inner wall of the T-shaped groove 9 is adapted to the T-shaped block 10. After the T-shaped block 10 is inserted into the T-shaped groove 9, the fit between the two restricts the displacement of the decorative panel 2 in the horizontal and vertical directions, only leaving the possibility of fine adjustment along the length direction of the T-shaped groove 9, so as to ensure the reliability of the connection.

[0024] With reference to Figure 1 , Figure 3 the left and right ends of the upper side of the rear surface of the decorative panel 2 are respectively connected with first clamping blocks 11 by bolts. The first clamping blocks 11 are fixed at the left and right edge positions of the upper side of the decorative panel 2 to provide a matching structure for the connection of the adjacent decorative panel 2 above. The rearwardly protruding middle section of the first clamping block 11 forms an insertion groove 12 with the rear surface of the decorative panel 2.

[0025] With reference to Figure 1 , Figure 3 the left and right ends of the lower side of the rear surface of the decorative panel 2 are respectively connected with second clamping blocks 13 by bolts. The second clamping blocks 13 are fixed at the left and right edge positions of the lower side of the decorative panel 2 and cooperate with the first clamping blocks 11 of the adjacent decorative panel 2 below. The middle section of the second clamping block 13 extends downward to form an insertion portion 14, which is adapted to the inner wall of the insertion groove 12. During installation, the insertion portion 14 can be inserted into the insertion groove 12 of the adjacent decorative panel 2 below, so that a snap fit is formed between the upper and lower decorative panels 2, which ensures the alignment and connection stability between the panels, enhances the integrity of the entire decorative panel 2 system, disperses the load of a single panel, and at the same time ensures that the gaps between the panels are uniform and aesthetically pleasing.

[0026] Working principle: In use, first, the transverse keel 3, which is U-shaped with an opening facing forward, is fixed to the front surface of the wall 1 through the L-shaped connecting corner brace 4: the vertical section of the L-shaped connecting corner brace 4 fits the wall 1, and is fastened to the wall 1 by chemical anchor bolts or expansion bolts to ensure the pull-out resistance, and its horizontal section is fitted and connected to the upper and lower surfaces of the transverse keel 3 through high-strength bolts, so as to transfer the load of the transverse keel 3 to the wall 1, and at the same time ensure the levelness of the transverse keel 3, so that the transverse keel 3 forms a multi-layer horizontal support frame at different height positions on the front surface of the wall 1.

[0027] Subsequently, the sliding assembly is used to adjust the horizontal position of the fixing block 8: the sliding block 6 is embedded in the sliding grooves 5 opened on the upper and lower surfaces of the transverse keel 3, forming a fit relationship with the sliding grooves 5 that only allows horizontal sliding. The front end of the sliding block 6 is fixed to the upper and lower ends of the rear surface of the connecting block 7, and the middle section of the sliding block, which protrudes rearward in a several-shaped structure, is embedded in the U-shaped inner cavity of the transverse keel 3 to enhance the stability during the sliding process. The bottom of the fixing block 8 is fixed to the upper surface of the upper sliding block 8, so that it can slide along the sliding groove 5 with the sliding block 6, and be adjusted to a position adapted to the installation requirements of the decorative panel 2.

[0028] Next, the decorative panel 2 is snap-fitted in place: the T-block 10 is fixed to the back surface of the decorative panel 2 with countersunk bolts, and the T-block 10 is inserted into the T-groove 9 of the fixing block 8 from top to bottom to achieve a reliable snap-fit ​​between the decorative panel 2 and the fixing block 8.

[0029] Finally, the connection of the upper and lower decorative panels 2 is completed: while the T-shaped block 10 is inserted downward into the T-shaped groove 9, the insertion part 14 of the second locking block 13 at both ends of the lower rear surface of the upper decorative panel 2 can be inserted into the middle section of the first locking block 11 at both ends of the upper left and right rear surface of the adjacent lower decorative panel 2 to form an insertion groove 12 with the rear surface of the decorative panel 2. The upper and lower decorative panels 2 are connected as a whole by the fitting and locking of the insertion part 14 and the insertion groove 12, which not only ensures the alignment and connection stability between the panels, but also distributes the load of the individual decorative panel 2, and ensures that the gaps between the panels are uniform and beautiful.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
