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

A vitrified tile paving structure is shown in figure 1 and comprises a mortar layer 1, a bonding layer 2, a gum layer 3 and a tile layer 4 which are connected layer by layer from inside to outside.

As shown in fig. 2, the mortar layer 1 is provided with five layers, each layer is integrally molded by casting, and the mortar layer comprises a plain ash layer 11, a cement mortar layer 12, a plain ash layer 11, a cement mortar layer 12 and a plain cement mortar layer 13 from inside to outside in sequence. The plain cement mortar layer 13 usually uses plain cement mortar as a bonding layer, the cement mortar is mortar prepared from cement, fine aggregate and water according to needs, and the waterproof purpose is achieved by means of the hydrophobic property of the mortar and the compactness of the mortar.

The first layer is a plain gray layer 11. Plain cement refers to a cement slurry without any material other than cement and water, and the water-cement ratio is usually 0.42. The cement mortar has the functions of bonding with the base layer and preventing water, and is formed by repeatedly scraping, so that pores on the surface of the base layer are blocked, and the anti-permeability and waterproof capabilities are enhanced.

The second layer is a cement mortar layer 12. The cement mortar is prepared from cement, fine aggregate and water according to needs, and achieves the waterproof purpose by means of the hydrophobic property of the mortar and the compactness of the mortar. And cement mortar is smeared before the plain ash of the first layer is not solidified, so that the two layers are firmly combined together to play the role of a framework of the whole waterproof layer and also serve as a protective layer of the plain ash layer 11, so that the cement is fully hydrated, crystallized and compacted, and the impermeability is enhanced.

The third layer is a plain gray layer 11. It is mainly waterproof, and is coated on the surface of rough and moist cement mortar layer 12, so that the cement is fully hydrated, the crystallization is more compact, no crack is produced, the capillary pore network of the waterproof layer is cut off, and the anti-permeability is greatly enhanced.

The fourth layer is a cement mortar layer 12 which plays the role of water proofing and protecting the lime layer 11 and is also the framework of the water proofing layer. The mortar is plastered and compacted before the third plain lime layer 11 is not solidified, is tightly combined with the plain lime layer 11, and is bonded with the front three layers into a whole, so that the compactness is improved.

The fifth layer is a plain cement slurry layer 13 which is coated with the cement slurry of the fourth layer together to smooth the surface, block the pores on the surface and enhance the anti-permeability performance of the waterproof layer.

The bonding layer 2 is a laminated structure formed by arranging an adhesive between the vitrified tile 41 and the mortar layer 1, and the adhesive consists of aggregate, Portland cement, a small amount of hydrated lime and functional additives according to the requirement of the quality level of a product. The adhesive has better affinity to the mortar layer 1 and can be used as an intermediate medium to play a main role in connecting and fixing the mortar layer 1 and the brick layer 4.

The back glue layer 3 is a laminated structure formed by uniformly coating the back glue of the vitrified tile 41 on the surface of the vitrified tile 41. The vitrified tile 41 back adhesive is an interface agent, is prepared by a high molecular polymer emulsion material and inorganic silicate according to a certain proportion, can effectively complex with the silicate and form hydrogen bonds, and greatly improves the bonding strength between the tile material and a bonding material. The liquid material component and the powder material component for preparing the back adhesive are uniformly mixed according to the weight ratio of 1: 2.5 and then coated on the back surface of the vitrified tile 41, the thickness is about 0.5mm, and the dosage is about 0.5 Kg/m 2.

The brick layer 4 is formed by laying a plurality of square vitrified tiles 41, a certain gap is left between the square vitrified tiles during laying, and the gap is filled with a filling agent after laying. As shown in fig. 3 and 4, the bottom surface of the vitrified tile 41 is provided with a transverse groove 42 at a transverse edge thereof, and the bottom surface of the vitrified tile 41 is provided with a longitudinal groove 43 at a longitudinal edge thereof, and the width of the groove bottom thereof is larger than that of the groove opening. A precast block 44 made of the material of the vitrified tile 41 is installed in the groove of the transverse groove 42 and the longitudinal groove 43, and as shown in fig. 5, the precast block 44 is in a wedge-shaped arrangement and comprises a wedge 441 and a wedge 442. As shown in fig. 3 to 5, the wedge 441 is engaged and adhered to the transverse groove 42 and the longitudinal groove 43, the wedge 442 has saw-tooth protrusions 46 on its side surface, and the vitrified tile 41 has a honeycomb 45 on its bottom surface. The arrangement of the transverse groove 42, the longitudinal groove 43, the prefabricated block 44 and the honeycomb 45 effectively increases the contact area between the vitrified tile 41 and the bonding layer 2, so that the connection force between the vitrified tile and the bonding layer is larger, and the vitrified tile is not easy to separate. The saw-toothed design of the wedge 442 makes it have a friction effect with the adhesive layer 2 in the direction perpendicular to the vitrified tile 41, and the adhesive layer 2 between the sawteeth on the surface of the wedge 442 needs to be deformed to be separated from it. The inclined groove wall design makes the bonding layer 2 be extruded by the groove wall when the bonding layer is separated from the vitrified tile 41, so that the bonding layer is difficult to separate. These designs greatly improve the ability of the brick layer 4 to be attached to the tie layer 2.

When the vitrified tile 41 is laid, the mortar layer 1 is laid layer by layer, after the mortar layer is dried, the back glue is evenly coated on the back surface of the vitrified tile 41 and the precast block 44, and after the mortar layer is dried, natural maintenance is carried out. Then, the prepared adhesive is coated on the back adhesive layer 3 and the mortar layer 1, then the vitrified tile 41 is pressed on the bonding surface, a rubber hammer is used for lightly knocking, adjusting the level, righting and compacting, and the redundant mortar is scraped. And performing joint filling operation after at least one week to finish the laying.
