Method for preventing mosaic hollowing and shedding of vitrified tiles

Abstract

The invention relates to a method for preventing mosaic hollowing and shedding of vitrified tiles. The method includes firstly, sticking fragmentary vitrified tiles with same thickness on the sticking faces of the vitrified tiles to enable the fragmentary vitrified tiles to be basically overspread; sticking a plurality of rebars on the sticking faces of the vitrified tiles, wherein the rebars are perpendicular to the vitrified tiles and the length of each rebar is 6-8mm larger than the thickness of each vitrified tile; after the fragmentary vitrified tiles and the rebars are firmly bound, mixing a cement adhesion agent into grout, evenly coating the grout on the surfaces of the fragmentary vitrified tiles to enable the surfaces to be textured, and plastering a composite portland cement layer on the textured fragmentary vitrified tiles after the grout is thoroughly dried, wherein the thickness of the composite portland cement layer ranges from 5mm to 8mm; painting a wall plastering base face between a shear wall and the composite portland cement layer after painting with the adhesion agent in advance. A construction process in which bonding and dry hanging of the vitrified tiles and mortar are combined is adopted, so that hollowing rate is reduced, and tile shedding caused by hollowing of the bonding layers of the vitrified tiles is prevented.

Description

Technical field [0001] The invention relates to the field of construction, in particular to a method for preventing the hollowing and falling of vitrified bricks inlaid. Background technique [0002] Vitrified (magnet) tiles are made by firing quartz sand and mud in a certain proportion, and then they are polished and bright but do not need to be polished. The surface is as smooth and translucent as a glass mirror. It is the hardest kind of all ceramic tiles. It absorbs water. Rate, edge straightness, bending strength, acid and alkali resistance, etc. are superior to ordinary glazed tiles, polished tiles and general marble. [0003] In the current building decoration construction, because the material of the vitrified brick is very dense, the bonding surface is smooth, the surface area is small, the bonding material penetrates into the vitrified brick and the "nail wedge effect" is very small. The whole brick The physical adsorption force produced is small. The vitrified brick is...

AI Technical Summary

Problems solved by technology

[0005] 1. The water retention of the bonding layer is too poor, and the water loss is too fast during the hardening and drying process, resulting in uneven shrinkage stress;

[0006] 2. Vitrified tiles are affected by temperature changes, resulting in damage to the bonding layer, resulting in hollowing
