step five: adhesive scraping agent for back of ceramic tile or rock plate: firstly, flattening the adhesive on the back of the ceramic tile or the rock plate by using a plane scraper, and then forcibly pulling the thickness of the groove adhesive layer on the flattened adhesive layer by using a tooth-shaped scraper to be not more than 5mm;
step six: paving ceramic tiles or rock plates: the method comprises the steps of firstly, completely splashing liquid cement paste on a leveling base layer, paving tiles or rock plates scraped with tile glue on the leveling base layer, reserving gaps of 0.3mm-0.5mm, and vibrating the tiles or the rock plates to the short side direction by using a paving vibrator to remove air;
step seven: and (3) tight joint leveling: when the close joint paving is vibrated by the paving vibrator and the leveling process is carried out, the adjacent surface layers are slightly uneven, the tile leveling device is used for leveling, small tiles are fully coated with 502 glue as leveling objects, the small tiles are pressed between the two adjacent surface layers for 30s-60s forcefully until the leveling objects are fixed, the hands are loosened, and then the next leveling is carried out;
step eight: removing leveling objects: after the whole house is paved for 48 hours, the leveling objects are sequentially removed from the early to the late according to the fixed time sequence of the leveling objects, and residual 502 glue marks are gently removed by a wallpaper knife.
Preferably, the humidity of the sand in the third step is qualified by grasping the sand in hands and falling to the ground.
Preferably, in the fourth step, if the construction site condition is required to exceed 5cm, the redundant part is leveled with concrete in advance, the basic layer is paved after the redundant part is completely solidified, and the periphery of the original wall body is filled with foam strips with the thickness of 5-10 mm.
Compared with the prior art, the invention has the beneficial effects that:
the invention effectively solves the problems of high paving cost, high construction difficulty, more later problems and the like under the close joint paving condition, can control the blank rate of close joint paving to be less than 2 percent and the stretch-break rate to be less than 2 percent, and also has the advantages of improving the beautiful paving effect, enhancing the construction quality, ensuring the simpler and more convenient construction and higher popularization rate and effectively reducing the construction cost.
Description of the embodiments
The invention provides a technical scheme that:
a close joint paving method for high-quality ceramic tiles and rock plates comprises the following steps:
step one: and (3) ground treatment: the ground dust is cleaned, the original layer cracks are checked and repaired, and the problem of fracture of the original layer cracks, which is caused by conduction to the surface layer, can be effectively avoided by the arrangement;
step two: checking the difference of the sizes of the laid tiles or rock plates: the errors of bilateral size comparison and oblique angle size comparison of corresponding tiles or rock plates are not more than 0.3mm, and the arrangement can prevent the problems of downtime and low experience of consumers caused by the fact that the problem of poor tile or rock plate ruler cannot meet the close joint paving condition, and can save unnecessary later-stage cost;
step three: tile or rock board treatment: removing dust such as a mold release agent on the back of the ceramic tile or the rock plate; the arrangement can avoid the problem of hollowing in the later stage caused by incomplete adhesion between the later-stage ceramic tile or rock board and the adhesive;
step four: paving a leveling base layer: cement, sand, water were first mixed with 1:5:1, stirring in proportion, adding a 23# non-galvanized iron wire with the diameter of 0.6mm in the middle when paving the leveling base layer, and preventing the problems of fracture of the leveling layer and the surface layer under the conduction of bottom layer cracks caused by heat expansion, cold contraction and the like after the iron wire and the base layer are solidified because the galvanized iron wire and cement cannot be completely solidified, wherein the thickness of the paving base layer is not more than 5cm;
step five: the adhesive is scraped on the back of the ceramic tile or the rock plate, the adhesive scraped on the back of the ceramic tile or the rock plate is selected according to the national standard of ceramic wall and floor tile adhesive jc/t 547-2017, and the adhesive is selected according to the surface layer material selection condition: firstly, flattening the adhesive on the back of the ceramic tile or the rock plate by using a plane scraper, wherein the arrangement can ensure that the adhesive can completely permeate and condense on the back of the ceramic tile or the rock plate, and then forcibly pulling a groove on the flattened adhesive layer by using a tooth-shaped scraper;
step six: paving ceramic tiles or rock plates: the method comprises the steps of firstly, completely splashing liquid cement paste on a leveling base layer, paving tiles or rock plates scraped with tile glue on the leveling base layer, reserving gaps of 0.3mm-0.5mm, and vibrating the tiles or the rock plates to the short side direction by using a paving vibrator to remove air;
step seven: and (3) tight joint leveling: when the close joint paving is vibrated by the paving vibrator and the leveling process is carried out, the adjacent surface layers are slightly uneven, the tile leveling device is used for leveling, small tiles are fully coated with 502 glue as leveling objects, the small tiles are pressed between the two adjacent surface layers for 30s-60s forcefully until the leveling objects are fixed, the hands are loosened, and then the next leveling is carried out;
step eight: removing leveling objects: after the whole house is paved for 48 hours, the leveling objects are sequentially removed from the early to the late according to the fixed time sequence of the leveling objects, and residual 502 glue marks are gently removed by a wallpaper knife.
The humidity of the sand in the step three can be clenched into clusters by hands, and the clusters are scattered on the ground to be qualified, so that the setting can ensure that the later leveling base layer and the wire gauze are solidified into a whole, and the problem of uneven surface layer caused by natural collapse of the leveling base layer due to overlarge humidity can be avoided; in the fourth step, if the construction site condition is required to exceed 5cm, the redundant part is required to be leveled by concrete in advance, and then the foundation layer is paved after the redundant part is completely solidified, because the leveling foundation layer is too thick and has fracture risk, if the surface layer is broken, the problem of cracking can be caused by fracture, the periphery of the original wall body is filled with foam strips of 5-10mm, and the risk of expansion of the leveling layer caused by micro deformation of the wall body due to the reasons of settlement of a house body and the like is effectively avoided.
