Description

Technical Field

[0001] This utility model relates to the field of dry-hanging device structure, specifically to a fine-tuning keelless dry-hanging device for decorative panels. Background Technology

[0002] Currently, the dry-hanging installation of interior wall decorative panels mostly uses fixed supports or L-shaped brackets to connect to the wall base. After leveling with horizontal and vertical joists, the steel plates are then fixed with screws or clips. However, the existing construction method has the following prominent problems: (1) The positioning is complicated and the installation efficiency is low: the support needs to be pre-lined and positioned, but the screw hole position is difficult to match the hanging point on the back of the decorative panel. The on-site installation accuracy is extremely high, and workers are prone to cumulative errors during operation, which often requires repeated adjustments and seriously affects the construction efficiency. (2) Material waste and space occupation: In order to achieve the flatness of the overall wall surface, it is usually necessary to lay the keel for leveling, which not only increases the amount of steel used and increases the construction cost, but the thickened keel layer also occupies the indoor space. (3) The quality of the seams depends on manual labor, making it difficult to ensure consistency: The existing system lacks effective automatic guidance and limiting mechanisms. When splicing panels, workers rely on visual observation and manual pushing and pulling to adjust, which can easily lead to uneven seam width and uneven surface, affecting the overall appearance; (4) Inconvenient maintenance and replacement: The existing hanging method is often easy to damage the board or the base frame when disassembling, and the maintainability and adjustability are poor, which is not conducive to the later pipeline maintenance or replacement of individual boards.

[0003] Therefore, the industry needs a dry-hanging device with a simpler structure and easier installation. An ideal new device would be able to make flexible fine-tuning in three dimensions, with automatic limiting and convergence functions to ensure flatness of the panels and uniformity of joints, thereby improving installation accuracy, construction efficiency, and ease of maintenance.

[0026] Reference Figure 1As shown, this utility model embodiment provides a fine-tuning keelless dry-hanging device for decorative panels, including a base assembly 30 and a support mechanism. The base assembly 30 is configured to be fixedly connected to the base wall 1. The support mechanism includes a panel 2 and a support member 5 for limiting the hooks 4 on the back of the decorative panel 3. The panel 2 and the base assembly 30 are movably connected by a connector. The support member 5 can accommodate at least one hook 4 on the back of the decorative panel 3, and the connector is configured to adjust the position of the support mechanism relative to the base assembly 30 in multiple directions.

[0027] Specifically, the base assembly 30 is fixed to the base wall 1 using expansion screws 29 or self-tapping screws. The specific connection method is not limited here. The base assembly 30 provides stable support for the entire dry-hanging system. The support mechanism supports the decorative panel 3 and limits the hooks 4 on the back of the decorative panel 3 via the support member 5, ensuring stable installation of the decorative panel 3. The connector is used to movably connect the support mechanism to the base assembly 30 and allows for multi-directional adjustment of the position of the support mechanism relative to the base assembly 30, enabling fine-tuning of the decorative panel 3. Through the synergistic action of the base assembly 30, the support mechanism, and the connector, rapid assembly and multi-directional fine-tuning of the decorative panel 3 are achieved. The base assembly 30 provides a stable foundation, the support mechanism limits the hooks 4 on the back of the decorative panel 3 via the support member 5, and the connector allows the support mechanism to be adjusted in multiple directions, ensuring the installation accuracy and overall appearance of the decorative panel 3. This device not only improves installation efficiency and accuracy but also ensures structural stability and safety, while facilitating later maintenance and replacement.

[0028] For example, in conjunction with reference Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the base assembly 30 is provided with at least a square hole 6, the panel 2 is provided with at least one third screw hole 7, and the top of the panel 2 is provided with two first screw holes 8; the connector includes a vertical screw 9, a horizontal screw 12 and an adjusting screw 10; the vertical screw 9 is configured to pass through the first screw hole 8 and abut against the top of the base assembly 30 at its bottom, the horizontal screw (12) is configured to pass through the second screw hole (11) and abut against the side of the base assembly (30), and the adjusting screw 10 is configured to pass through the elongated hole 33, the square hole 6 and the third screw hole 7 at the same time, and the adjusting screw 10 can slide laterally or axially in the square hole 6.

[0029] Specifically, panel 2 is the main part of the support mechanism, used to support decorative panel 3. Panel 2 has at least one third screw hole 7 for engaging with adjusting screw 10, and two first screw holes 8 on the top of panel 2 for engaging with vertical screws 9 to achieve vertical adjustment. By rotating the vertical screws 9, the worker can move the vertical screws 9 up and down within the first screw holes 8 of panel 2, thereby adjusting the vertical position and level of panel 2.

[0030] The panel 2 is also provided with at least one second screw hole 11, and the connector also includes a transverse screw 12, which is configured to pass through the second screw hole 11 and abut against the side of the base assembly 30. By rotating the transverse screw 12, the transverse screw 12 moves horizontally within the second screw hole 11 of the panel 2, thereby adjusting the horizontal position of the panel 2. That is, the adjusting screw 10 and the transverse screw 12 can jointly adjust the horizontal position of the support mechanism to improve stability.

[0031] To improve the installation stability of the support mechanism, preferably, the base assembly 30 is provided with a square hole 6 for cooperating with the adjusting screw 10 and the washer 32. In this embodiment of the present invention, the adjusting screw 10 adopts a screw structure. The height setting of the square hole 6 allows the adjusting screw 10 to move up and down to cooperate with the height adjustment of the vertical screw 9. The lateral width setting of the square hole 6 allows the support mechanism to have fine adjustment functions in the inner and outer directions. The third screw hole 7 can cooperate with the adjusting screw 10 to achieve a stable connection, thereby realizing the three-dimensional adjustment function in the vertical, lateral, and inner and outer directions.

[0032] It should be noted that the number of adjusting screws 10, vertical screws 9, and horizontal screws 12 is not limited here, and can be set according to actual needs. For ease of understanding, in this embodiment of the utility model, there is one square hole 6, one adjusting screw 10, two vertical screws 9, two first screw holes 8, one horizontal screw 12, and one second screw hole 11. Of course, in other embodiments, there can be two or three square holes 6 and adjusting screws 10, and there can be only one, three or four vertical screws 9 and first screw holes 8, and there can also be only one, three or four horizontal screws 12 and second screw holes 11.

[0033] For example, in conjunction with reference Figure 2 , Figure 3 Figure 4As shown, the base assembly 30 includes a first vertical plate 13, a first horizontal plate 14, a second vertical plate 15, and a second horizontal plate 16. The first vertical plate 13 is fixedly connected to the base wall 1. The first horizontal plate 14 is located at the bottom of the first vertical plate 13, extending outwards and perpendicularly connected to the first vertical plate 13. The second vertical plate 15 is located at the free end of the first horizontal plate 14, perpendicularly connected to the first vertical plate 13, and the first horizontal plate 14 is situated between the upper and lower ends of the second vertical plate 15. The second horizontal plate 16 is located at the top of the second vertical plate 15, extending towards the base wall 1, and a first gap 1 exists between the second horizontal plate 16 and the first vertical plate 13. 7. A second gap 31 exists between the first vertical plate 13 and the second vertical plate 15. The square hole 6 is located between the first horizontal plate 14 and the second horizontal plate 16. The second gap 31 is configured to allow an external tool to be inserted into the second gap 32 to adjust the adjusting screw 10. Preferably, a shim 32 is movably disposed within the second gap 31. The shim 32 has an elongated hole 33. The adjusting screw 10 is configured to pass through the square hole 6, the third screw hole 7, and the elongated hole 33 simultaneously. The adjusting screw 10 can slide axially within the elongated hole 33. When the adjusting screw 10 slides laterally within the square hole 6, the adjusting screw 10 can drive the shim 32 to move laterally. The shim 32 is fitted against the second vertical plate 15.

[0034] Combined with reference Figure 5 and Figure 6 As shown, panel 2 includes a horizontal panel 18 and a vertical panel 19. The horizontal panel 18 is vertically disposed on top of the vertical panel 19 and extends toward the base assembly 30. The horizontal panel 18 is disposed above the second horizontal plate 16. A first screw hole 8 is disposed on the horizontal panel 18. The bottom of the vertical screw 9 can abut against the top of the second horizontal plate 16. A third screw hole 7 and a second screw hole 11 are disposed on the vertical panel 19. The bottom of the horizontal screw 12 can abut against the outer side of the second vertical plate 15.

[0035] The structure of the support member 5 is not limited in this embodiment of the utility model. Specifically, it can be set according to the hook 4 on the back of the decorative panel 3. For example, the support member 5 includes a support base plate 20 and a baffle 21. The support base plate 20 extends outward perpendicular to the longitudinal panel 19. The baffle 21 is connected to the support base plate 20 at a horizontal position and extends upward. The baffle 21 is perpendicular to the support base plate 20.

[0036] Furthermore, the support member 5 is configured to accommodate hooks 4 on the back of at least two decorative panels 3, and a clamping member 22 is provided on the support base plate 20. The clamping member 22 is used to push the backs of multiple decorative panels 3 on the support member 5 together. The support member 5 can accommodate multiple decorative panels 3 simultaneously, reducing the complexity of the installation process and improving installation efficiency. The pushing action of the clamping member 22 ensures uniform seams between decorative panels 3, improving the overall visual quality. It should be noted that the number of hooks 4 accommodated by the support member 5 is not limited here and can be set according to actual needs. The support member 5 can accommodate only one hook 4 on the back of a decorative panel 3, in which case the clamping member 22 is not required. When two, three, four, or other hooks 4 are installed on the back of decorative panels 3, the clamping member 22 can be installed to improve the flatness of the splicing between multiple decorative panels 3.

[0037] By way of example, in this embodiment of the present invention, the support 5 is configured to accommodate the hooks 4 on the back of the two decorative panels 3, as shown in the figure. Figure 7 As shown, the clip 22 includes a transverse support plate 23. The transverse support plate 23 has a first slot 24 and a second slot 25 at both ends. The transverse support plate 23 has a first elastic steel clip 26 and a second elastic steel clip 27 on both sides above it. The first slot 24 and the second slot 25 are respectively used to be installed on the two opposite free ends of the support base plate 20. The first elastic steel clip 26 and the second elastic steel clip 27 are used together to push the multiple decorative panels 3 together.

[0038] Specifically, the first slot 24 and the second slot 25 are respectively installed on the two opposite free ends of the support base plate 20 to ensure the stable fixation of the clamping member 22. The first elastic steel clip 26 and the second elastic steel clip 27 are fixed on both sides above the transverse support plate 23 and cooperate with the back of the decorative panel 3 on the support member 5. The elastic pushing action of the first elastic steel clip 26 and the second elastic steel clip 27 ensures that the joints between the decorative panels 3 are uniform and improves the overall appearance quality. As a preferred embodiment of this utility model, the size of the slots of the first slot 24 and the second slot 25 is adapted to the thickness of the support base plate 20 to improve the installation stability of the clamping member 22.

[0039] Preferably, the baffle 21 is provided with a first through hole 28, which is used for adjusting the adjusting screw 10 after an external tool is inserted; the first vertical plate 13 is fixed to the base wall 1 by expansion screws 29 or self-tapping screws, and the position of the first vertical plate 13 by the expansion screws 29 or self-tapping screws is higher than that of the second horizontal plate 16. Preferably, the first through hole 28 is aligned with the adjusting screw 10 to ensure that an external tool can be inserted for adjustment without disassembling the baffle 21, thus improving the convenience and efficiency of adjustment.

[0040] It should be noted that the "three-dimensional adjustment + automatic seam alignment + keel-free" hanging concept provided in this utility model embodiment is applicable to the dry-hanging installation of various decorative materials such as enamel steel plates, aluminum plates, ceramic plates, and composite metal plates. The four forms of clips and hooks can be adjusted according to the back structure of different materials (dovetail groove, round hole, tongue and groove), while still maintaining the three-way adjustment and automatic limit function. In other embodiments, in addition to screws, the connecting parts can also adopt non-screw quick-release structures, such as spring clips, eccentric wheels, sliders + locking parts, etc. There are no restrictions here. Electric or intelligent adjustment can also be used to replace manual screw fine adjustment. The automatic seam alignment mechanism can also adopt magnetic attraction, wedge blocks, or plug-in guide components.

[0041] Overall, in this embodiment of the utility model, the base component 30 and the support mechanism adopt an integrated structure. Workers can complete the positioning simply by turning the adjusting screws, eliminating the tedious process of repeated line laying, measurement, and disassembly. Construction is more convenient and efficient. The vertical screw 9 and the horizontal screw 12 can be operated independently to achieve precise fine-tuning of the height, horizontal position, and inner and outer directions of the plate, effectively ensuring the flatness of the installation. Under the action of the clamp 22, the joint automatically closes and is limited. The elastic steel strip attached to the clamp 22 can guide adjacent plates to automatically approach and stably limit their position at the designed joint, significantly improving the uniformity of the joint and reducing the error caused by manual adjustment. This utility model embodiment, through structural optimization, eliminates the need for horizontal and vertical keels in traditional methods, significantly reducing steel consumption, saving resources and reducing construction costs. During disassembly, the plates and support mechanisms can be easily removed without damaging the base and wall substrate, greatly facilitating later maintenance, replacement, or upgrades. The load is transferred to the support mechanism through the hooks 4 on the back of the plates, and then finally to the wall through the base assembly 30. The entire force transmission path is clear, the structure is stable, and the system's load-bearing capacity and safety are significantly improved.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model. It should be noted that the structures or components illustrated in the accompanying drawings are not necessarily drawn to scale, and descriptions of well-known components, processing techniques, and processes are omitted to avoid unnecessarily limiting the utility model.
