Description

Fixing device for external wall ceramic decorative sheet Technical Field The utility model relates to the technical field of ceramic sheet fixing devices, in particular to a fixing device for an external wall ceramic decorative sheet. Background When the high-rise building outer wall is constructed, from the perspective of environmental protection, the outer wall adopts the ceramic decorative sheet to better meet the requirements of modern energy conservation and environmental protection, and the ceramic decorative sheet also has longer-term sustainable development. The traditional dry-hanging ceramic decorative sheet is influenced by practical requirements, construction condition requirements and other factors, the construction technology is complex, and the construction cost is high. According to the fixed hanging structure of the ceramic sheet disclosed by the utility model with the publication number of CN221219470U in the prior art, the first hanging piece, the second hanging piece and the rail keel are connected with the corresponding ceramic sheet, and then the first hanging piece and the second hanging piece are hung on the rail keel, so that the upper ceramic sheet and the lower ceramic sheet are independently hung and carried, the accumulated load and gravity shear generated by vertical installation are decomposed, the ceramic sheet is prevented from falling off due to the deviation of gravity in the whole vertical face, the construction cost is greatly reduced, and the anti-falling measure is achieved by using a buckling mode in the prior art, but the ceramic sheet is required to be installed through the rail keel and then fixed through hanging of the hanging piece, the ceramic sheet is also required to be fixed on the hanging piece through adhesion, the structure is complex, the installation steps are many, and the ceramic sheet is easy to fall off only through adhesion with the hanging piece for a long time, in addition, after the rail keel is fixedly installed, when the position is slightly deviated, the ceramic sheet is not flat in installation, the adjustment of the height is difficult, the rail keel is required to be detached, and the outer wall is inconvenient to use, so that the ceramic sheet is very fixed by the ceramic sheet is very provided. Disclosure of Invention The utility model aims to provide a fixing device for an external wall ceramic decorative sheet, which has the advantages of simple structure, convenience in installation, capability of realizing vertical position adjustment and improvement of construction efficiency. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a fixing device of sheet metal is decorated to outer wall ceramic, includes expansion screw subassembly and L type aluminum alloy fastener, the vertical part of L type aluminum alloy fastener is equipped with waist type hole, and horizontal part extends to T shape pterygoid lamina, waist type hole is used for adjusting the vertical position of fastener, expansion screw subassembly includes plastics expansion pipe and screw, the screw passes waist type hole and plastics expansion union coupling, is fixed in the wall body with the fastener, adjacent ceramic decoration sheet metal about the T shape pterygoid lamina buckle. By adopting the technical scheme, the utility model has the following advantages: The waist-shaped hole and the expansion screw component are matched, so that the L-shaped aluminum alloy fastener can flexibly adjust the vertical position on the expansion screw component, the expansion screw component and the L-shaped aluminum alloy fastener are not required to be repeatedly disassembled, and the construction efficiency is improved. Further, the vertical two side surfaces of the L-shaped aluminum alloy fastener are provided with evenly distributed textures. By adopting the technical scheme, the utility model has the following advantages: The texture arrangement of the utility model can increase the friction force between the L-shaped aluminum alloy fastener and the wall surface and the back surface of the ceramic decorative sheet, and can effectively prevent the ceramic decorative sheet from slipping due to external force or vibration. Further, after the screws and the plastic expansion pipes are installed, the screws and the plastic expansion pipes are covered by sealant, and the T-shaped wing plates are exposed out of the surface of the ceramic decorative sheet. By adopting the technical scheme, the utility model has the following advantages: The sealing glue covers the screw and the plastic expansion pipe, is only used as a functional part, is exposed out of the T-shaped wing plate, can effectively prevent the screw, the ceramic decorative sheet and the L-shaped aluminum alloy fastener from being exposed out of the environment, and can prevent corrosion, and the sealing glue can play a role in protecting and s
