Description

Technical Field

[0001] This utility model relates to the technical field of ceramic thin plate fixing devices, and more specifically to a fixing device for exterior wall ceramic decorative thin plates. Background Technology

[0002] From an environmental perspective, using ceramic decorative thin panels for the exterior walls of high-rise buildings is more in line with modern energy-saving and environmental protection requirements, and also has a longer-term sustainable development potential. Traditional dry-hanging ceramic decorative thin panels are subject to factors such as actual needs and construction conditions, resulting in complex construction techniques and high costs.

[0003] The existing technology, disclosed in utility model CN221219470U, describes a fixed mounting structure for ceramic thin plates. This structure uses a first hanger, a second hanger, and a track keel. The first and second hangers connect the corresponding ceramic thin plates, and are then hung on the track keel. This allows the upper and lower ceramic thin plates to be independently mounted and supported, distributing the accumulated load and gravitational shear force generated by vertical installation on the overall facade. This prevents the ceramic thin plates from shifting and falling due to gravity. The existing technology uses a snap-on method, significantly reducing construction costs and providing an anti-fall-off measure. However, this utility model still has the following problems: This utility model requires the installation of track keel, and then the fixing by hanging brackets. It also requires the ceramic thin plate to be glued and fixed to the hanging brackets. The structure is complicated and the installation steps are many. Moreover, the fixing by gluing only to the hanging brackets is not firm and is easy to fall off over time. In addition, after the track keel is fixed and installed, when there is a slight deviation in position that causes the ceramic thin plate to be uneven, it is difficult to adjust the height. It is necessary to disassemble the track keel and reinstall it, which is very inconvenient to use. Therefore, this utility model proposes a fixing device for exterior wall ceramic decorative thin plates. Summary of the Invention

[0004] The purpose of this utility model is to provide a fixing device for thin ceramic decorative panels for exterior walls, which has a simple structure, is easy to install, and can adjust the vertical position, thereby improving construction efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fixing device for exterior wall ceramic decorative thin panels includes an expansion screw assembly and an L-shaped aluminum alloy fastener. The L-shaped aluminum alloy fastener has a waist-shaped hole in its vertical part and extends into a T-shaped wing plate in its horizontal part. The waist-shaped hole is used to adjust the vertical position of the fastener. The expansion screw assembly includes a plastic expansion tube and a screw. The screw passes through the waist-shaped hole and connects to the plastic expansion tube to fix the fastener to the wall. The T-shaped wing plate snaps onto adjacent ceramic decorative thin panels.

[0007] By adopting the above technical solution, this utility model has the following advantages:

[0008] The design of this utility model, featuring an expansion screw assembly, an L-shaped aluminum alloy fastener, and a T-shaped wing plate, allows the L-shaped aluminum alloy fastener to be fixed to the wall via the expansion screw assembly, while the ceramic decorative thin plate can be fixed within the T-shaped wing plate via clips. The structure is simple and installation is convenient. Furthermore, the combination of the slotted hole and the expansion screw assembly allows for flexible vertical position adjustment of the L-shaped aluminum alloy fastener on the expansion screw assembly, eliminating the need for repeated disassembly of the expansion screw assembly and the L-shaped aluminum alloy fastener, thus improving construction efficiency.

[0009] Furthermore, the vertical two-sided surfaces of the L-shaped aluminum alloy fastener are provided with uniformly distributed textures.

[0010] By adopting the above technical solution, this utility model has the following advantages:

[0011] The textured design of this invention increases the friction between the L-shaped aluminum alloy fastener and the wall surface and the back of the ceramic decorative panel, effectively preventing the ceramic decorative panel from slipping off due to external force or vibration.

[0012] Furthermore, the screws and plastic expansion tubes are covered with sealant after installation, and the T-shaped wing is exposed on the surface of the ceramic decorative sheet.

[0013] By adopting the above technical solution, this utility model has the following advantages:

[0014] This utility model uses sealant to cover screws and plastic expansion tubes, and only exposes the T-shaped wing plate of the functional component. This effectively prevents screws, ceramic decorative thin plates and L-shaped aluminum alloy fasteners from being exposed to the outside, preventing corrosion. In addition, the sealant can protect the sealed internal components and extend the service life of this utility model.

[0015] Furthermore, the length direction of the waist-shaped hole is parallel to the vertical axis of the L-shaped aluminum alloy fastener.

[0016] By adopting the above technical solution, this utility model has the following advantages:

[0017] The horizontal alignment of the waist-shaped hole with the vertical axis of the L-shaped aluminum alloy fastener ensures the flatness of the ceramic decorative thin panel during installation.

[0018] Furthermore, the T-shaped wing plate is closely fitted to the ceramic decorative sheet on the side near the L-shaped aluminum alloy fastener.

[0019] By adopting the above technical solution, this utility model has the following advantages:

[0020] The T-shaped wing plate of this utility model is designed to fit tightly against the ceramic decorative sheet, which can effectively fasten the ceramic decorative sheet and prevent it from shifting. Attached Figure Description

[0025] like Figures 1 to 2 As shown in this specific embodiment, a fixing device for an exterior wall ceramic decorative thin panel includes an expansion screw assembly and an L-shaped aluminum alloy fastener 3. The vertical portion of the L-shaped aluminum alloy fastener 3 has a waist-shaped hole 6, and the horizontal portion extends into a T-shaped wing plate 5. The waist-shaped hole 6 is used to adjust the vertical position of the fastener. The expansion screw assembly includes a plastic expansion tube 2 and a screw 1. The screw 1 passes through the waist-shaped hole 6 and connects to the plastic expansion tube 2 to fix the fastener to the wall. The T-shaped wing plate 5 snaps onto adjacent ceramic decorative thin panels 7. The vertical surfaces of the L-shaped aluminum alloy fastener 3 are provided with uniformly distributed textures 4. After installation, the screw 1 and the plastic expansion tube 2 are covered with sealant, and the T-shaped wing plate 5 is exposed on the surface of the ceramic decorative thin panel 7. The length direction of the waist-shaped hole 6 is parallel to the vertical axis of the L-shaped aluminum alloy fastener 3. The side of the T-shaped wing plate 5 closest to the L-shaped aluminum alloy fastener 3 is tightly fitted to the ceramic decorative thin panel 7.

[0026] Through the above configuration, the expansion screw assembly, L-shaped aluminum alloy fastener 3, and T-shaped wing plate 5 of this utility model allow the L-shaped aluminum alloy fastener 3 to be fixed to the wall via the expansion screw assembly, and the ceramic decorative thin plate 7 to be fixed within the T-shaped wing plate 5 via clips. The structure is simple and installation is convenient. The cooperation between the waist-shaped hole 6 and the expansion screw assembly allows the L-shaped aluminum alloy fastener 3 to be flexibly adjusted vertically on the expansion screw assembly, thus eliminating the need for repeated disassembly of the expansion screw assembly and the L-shaped aluminum alloy fastener 3, improving construction efficiency. Furthermore, the lateral displacement of the L-shaped aluminum alloy fastener 3 can be adjusted by adjusting the position of the screw 1 within the plastic expansion tube 2. The waist-shaped hole 6 is formed by a stamping process, simplifying the manufacturing process and effectively reducing manufacturing costs. The screw 1 is a φ6*60mm screw. The texture 4 design increases the friction between the L-shaped aluminum alloy fastener 3 and the wall surface and the back of the ceramic decorative thin plate 7, effectively preventing the ceramic decorative thin plate 7 from slipping due to external force or vibration. The sealant covering the screw 1 and plastic expansion tube 2, with only the T-shaped wing plate 5 exposed as a functional component, effectively prevents the screw 1, ceramic decorative thin plate 7, and L-shaped aluminum alloy fastener 3 from being exposed to the outside, preventing corrosion. The sealant also protects the sealed internal components, extending the service life of this invention. The parallel alignment of the length of the waist-shaped hole 6 with the vertical axis of the L-shaped aluminum alloy fastener 3 ensures the flatness of the ceramic decorative thin plate 7 during installation. The tight fit between the T-shaped wing plate 5 and the ceramic decorative thin plate 7 effectively secures the ceramic decorative thin plate 7, preventing displacement.

[0027] Working principle: When installing the ceramic decorative thin panel 7 using this utility model, it is necessary to confirm the installation position and spacing of the L-shaped aluminum alloy fastener 3 in advance according to the drawings, draw a baseline on the wall, fix the plastic expansion tube 2 by drilling holes in the wall, and then flatten the L-shaped aluminum alloy fastener 3 on the wall. Pass the screw 1 through the waist-shaped hole 6 of the L-shaped aluminum alloy fastener 3 and screw it into the plastic expansion tube 2 for initial fixation. When there is a deviation between the height of the L-shaped aluminum alloy fastener 3 and the baseline, the vertical height of the L-shaped aluminum alloy fastener 3 can be adjusted by loosening the screw 1 to align it with the baseline, and then tighten the screw 1. There is no need to repeatedly disassemble and reassemble. Apply sealant to the screw 1, the plastic expansion tube 2 and the L-shaped aluminum alloy fastener 3 for further fixation and protection. Then, the ceramic decorative thin panel 7 is clipped into the T-shaped wing plates 5 at the top and bottom ends and fixed to the wall by wet application. The ceramic decorative thin panel 7 can be effectively fixed by cooperating with the T-shaped wing plates 5.

[0028] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
