Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-4, an exemplary embodiment of the present application provides a construction facing sheet structure, which includes a facing sheet body 1 and a gum base layer 2, wherein the facing sheet body 1 is one of a flexible face brick, a modified inorganic powder composite construction facing sheet, a soft porcelain, a soft stone flexible facing material or a soft stone flexible facing sheet material, and the surface of the facing sheet body 1 has a pattern 11. The glue base layer 2 is arranged on the back of the facing sheet body 1, the bottom surface of the glue base layer 2 is fixedly connected with the back of the facing sheet body 1 through glue, the glue base layer 2 is used for gluing during construction, and the facing sheet body 1 is glued to a building wall. Specifically, the size of the gum base layer 2 is the same as that of the facing sheet body 1, and the surface of the gum base layer 2 is provided with a rough surface made of fine sand, so that the contact between the gum base layer 2 and the adhesive can be increased. Set up a plurality of injecting glue holes 3 on the glue base layer 2, injecting glue hole 3 communicates the back of veneer sheet body 1, and the adhesive is paintd on glue base layer 2, and the viscose gets into injecting glue hole 3 of glue base layer 2 at the rubber coating process, can realize more firm effect of pasting.
