Description

Technical Field

[0001] The present application relates to the technical field of interior decoration, and particularly to a prefabricated wall panel structure for interior decoration that can be repeatedly disassembled and assembled and a disassembly method thereof. Background Art

[0002] During interior decoration, sometimes it is necessary to paint the interior wall surface to renovate the wall; it is also possible to install decorative wall panels on the interior wall surface to achieve the effect of renovating the wall. Among them, a decorative wall panel is a wall panel with a decorative pattern designed on one side for decorative purposes.

[0003] Currently, when installing a decorative wall panel, generally, silicone glue needs to be applied to the back of the decorative wall panel first, and then the decorative wall panel is pressed at a designated position on the wall surface so that the silicone glue on the back of the decorative wall panel contacts the wall surface, thereby enabling the silicone glue to fix the decorative wall panel to the wall surface.

[0004] After renovating the interior wall surface through the above-mentioned related technologies, when it is necessary to change the decorative pattern of the wall, it is necessary to pry the original decorative wall panel off the wall, which easily causes damage to the original decorative wall panel and is difficult to achieve the effect of reuse, resulting in waste of resources, so it needs to be improved. Summary of the Invention
