Introduction of Several Construction Techniques of Vitrified Brick
Traditional wet paste process
The traditional paving method-thick adhesion method or back adhesion method, cement, sand, liquid glue, etc. are mixed at the construction site, so the material quality is difficult to control, and the cement quality, sand thickness and silt content are difficult to control. In the proportioning process of cement mortar, whether the proportioning is reasonable, whether the material dosage is in place, and whether the mixing is uniform will affect the quality of cement mortar. The bonding strength is low, and it is not suitable for ceramic tiles with large specifications and small water absorption. It is easy to produce hollowing and falling off. The operation requires high craftsmanship of workers, the flatness and verticality of the wall surface are not easy to be controlled, and the board joints are easy to spread with salt frost, thus affecting the appearance. The traditional wet paste method has the advantage of lower cost.
Technology of dry hanging wall brick
Vitrified brick dry hanging method, in a way that does not use cement sand construction, on the back of the tile implanted bolt accessories, large tiles installed on the wall. Compared with the traditional wet operation process, the process eliminates the grouting process, can shorten the construction period, effectively prevent the salt-alkali and other pigments in the grouting from the surface of the penetration pollution, improve its decorative quality and perception effect, and more importantly, increase the safety, avoid the wet process of hollowing, cracks, shedding and other shortcomings. The disadvantage of this process is that the steel frame is used in indoor space, the side is not easy to close, the impact resistance is poor, the thickness of the ceramic tile is required to be more than 12mm, and the disadvantage is that it is expensive.
Wet wall brick hanging process
According to the design requirements in advance in the surface of the base hole, embedded expansion bolts or with hardwood wedge copper wire fixed in the hole. Before installation, drill the nose hole with a diameter of 5mm with a drill bit according to the design requirements of the veneer, and penetrate the copper wire into the hole. Use copper wire to bind and fix the embedded bolts on the plate and the structure surface. The gap between the plate and the base (I. e. grouting thickness) is generally 20-50mm. The method of wet hanging can prevent wall tiles from falling and hurting people. However, the problem of empty drum and falling off of vitrified bricks has not been solved, and the construction efficiency of workers is low and the cost is relatively high.
Ceramic tile adhesive process
Tile adhesive, directly mixed with water can be used, the quality standard is easy to control, high bonding strength. Workers are easy to operate, and the efficiency of paving bricks is greatly improved. Adhesive force is several times of cement mortar, can effectively paste large tiles, stone, to avoid the risk of brick. Good flexibility to prevent hollowing. No need to dip brick wet wall, improve construction efficiency. Good water resistance, avoid crevice spit white pan salt cream. The size and weight of the larger brick paving, compared to the dry hanging method can save costs. Old tiles, mosaic finishes renovation, the use of tile glue can be directly pasted on the surface, do not need to knock out the old finishes, time-consuming and labor-consuming. Special base surface: gypsum board, Etterboard, cement fiber board, insulation board, wood board, steel plate. However, the tile glue paste process requires higher flatness and verticality of the wall, and the cost is higher than that of ordinary cement mortar.
Comparative Analysis of Several Construction Technology Cost
As can be seen from the above, tile glue has excellent process characteristics, the cost is relatively low, more suitable for tile paving construction, suitable for vitrified brick wall paste, can prevent empty drum, fall off.
