What is the allowable deviation of the surface flatness of the general floor tile surface How to ens

The height difference of adjacent bricks shall not be exceeded.

1. Verticality standard: The verticality of the façade of the tile should generally be within 3mm.

2. Perpendicularity inspection method: The deviation value can be detected by using a 2m vertical detection ruler.

3. Close the left side of the vertical detection ruler to the measured surface, and then read the scale value pointed by the pointer after the pointer stops swinging by itself, which is the deviation of the verticality of the measured surface, and each grid is 1mm.

4. Flatness standard: the flatness error of ceramic tiles shall not exceed 2, and the height difference of adjacent bricks shall not be exceeded.

5. Flatness inspection method: When detecting the flatness of ceramic tiles, it can be detected with a vertical detection ruler, or it can be detected with a 2m ruler and a wedge-shaped feeler gauge.

6. When using the latter method to detect, the side of the ruler is close to the measured surface, and the size of the gap is detected with a contract-shaped feeler gauge.

7. Three points should be detected at each place, that is, one point vertically, and one point should be crossed at 45 ° on the left and right sides of its original position, and the average value of the three points should be taken.

8. Floor tiles are a kind of ground decoration material, also called floor tiles.

9. It is made of clay firing, with a variety of specifications, firm quality, small bulk density, pressure resistance, wear resistance and moisture resistance.

10. After glazing, it plays a decorative role, and is mostly used for the ground and floor of public buildings and civil buildings.

11. There are many varieties of floor tiles, and there is a lot of room to choose from, which can be divided into glazed bricks, full-body bricks, non-skid bricks, polished bricks, vitrified tiles, etc.

The national flatness requirement of floor tiles is that the deviation is less than , and the maximum value is not more than 2mm.

According to the requirements of the "GB4100-2006 National Standard for Ceramic Tiles", the floor tiles should leave different gaps according to the different paving positions. For example, in the kitchen and bathroom, the seamless wall tiles are paved, and the size of the joints should generally be about 1 mm - mm, not less than 1 mm.

If you need to pave the floor tiles to create a special decoration effect, you can widen the gap, such as 5mm. Similar to antique bricks or exterior wall tiles, balcony strip tiles, etc., the gap left is a wide joint. If it is paved with living room floor tiles, you can leave a gap of millimeters - 2 millimeters when paving.

The flatness requirements of floor tiles are that the flatness deviation is less than and the maximum value is not more than 2mm. If the 600*600 specification tile is used, the deviation value of its flatness should be between to and the maximum value should not exceed 2mm. The flatness requirements of ceramic tile paving are measured by a two-meter ruler, the flatness deviation is not more than 2mm, and the height difference of adjacent tile joints is not exceeded.

Floor tile engineering construction technology and acceptance standards.

1. Ceramic tile acceptance criteria 1. Look at the surface: glazed bricks, smooth and delicate glaze; The glossy glaze should be crystal shiny and shiny, while the matte glaze will be soft and comfortable. You can use a hard object to scrape the surface of the tile, if there is a scratch, it means that the glaze is insufficient, after the glaze on the surface is polished, the brick surface is easy to hide dirt, and it is difficult to clean.

Polished whole body brick, the polishing surface is smooth, no slag and no dust, and it is smooth and delicate to the touch. 2. Look at the color difference: put several ceramic tiles together, carefully inspect under the light, there is basically no color difference between good products, and the color tone between the products is basically the same; The color difference of the poor product is larger, and the color shade between the products is different (different batches of excellent bricks out of the kiln due to the slight deviation of the proportion of pigment or the deviation of the calcination temperature change will be poor, which is an unavoidable problem, the existence of color difference is normal, but the color will be relatively close, and it is almost difficult to distinguish with the naked eye).

3. Look at the specifications: the deviation of good product specifications is very small (the normal deviation value is that after paving, the product is neat and uniform, the brick joints are straight, and the decorative effect is good.) Poor product specifications deviate greatly, and the size of the products is not the same.

4. Look at the deformation: you can directly observe it with the naked eye. The product is required to be flat on the straight side, the product is not deformed, the construction is convenient, and the brick surface is smooth and beautiful after paving.

Look at the pattern: the pattern should be delicate and realistic, and there should be no obvious defects such as lack of color, broken lines, and dislocation. 5. Listen to the sound:

Knocking on the tile, the crisper and louder the sound, the better the density, the higher the proportion of porcelain, and the superior in terms of strength and water absorption.

The flatness of the floor tiles shall be checked with a 2-meter level, the error shall not exceed mm, the height difference of adjacent bricks shall not exceed mm, the straightness of the gap shall not be 3 mm, and when the floor tiles are laid, other types of work shall not be polluted and shall not be stepped on artificially. The floor tiles are cleaned 24 hours after completion, cleaned and maintained.

If there is an urgent need, I will ask the construction company.

What are the reasons for uneven tiles?

First, the tile itself factors.

1. Tiles are fired at high temperature and high pressure, and there will be some arched back more or less. After the precise selection of the machine, this arched back phenomenon exists in the standard limit, and generally will not have an impact on the paving, so when buying ceramic tiles, it is best to choose the top ten brands of ceramic tiles such as large manufacturers, and the high-quality tiles produced under the production capacity and monitoring of large manufacturers, so that the purchase is at ease.

2. Tile warping. The main reason for the formation of tile warping is that the tile has not been completely burned through, and the high-temperature material used in the tile formula is used, and many small manufacturers have added low-temperature materials for fast burning. During the firing process, the burned-through low-temperature material wraps around the high-temperature material and forms vitrification on the surface, but the internal material is not completely vitrified or porcelainized.

Therefore, after paving, due to the influence of cement tensile force and environment, the ** deformation warped angle.

Second, environmental factors.

1. Foundation deformation. The building will have a certain degree of settlement due to geological problems, different positions, different forces, inconsistent settlement degrees, and the ground will be uneven after a long time, and the tiles will be uneven.

2. The temperature difference varies greatly. The influence of the change of temperature and humidity in the four seasons, the ceramic tile will be deformed when the temperature is too low or too high. In winter, when the temperature in the north is too low, the moisture in the cement mortar binder will freeze, expand in volume, and destroy the structure and strength of the cement mortar, in this case, the tiles will become bulging.

The ceramic tile is in high temperature for a long time, and it will also be deformed.

Paving unevenness of more than 3 mm is the construction quality is unqualified, tile itself uneven error is too large, is the material is unqualified.

When the brick corners are not flat, the brick corners are uneven, and the quality of the tiles themselves is generally the majority. The tile is arched, low around and high in the middle, similar to the shape of the pot lid, but the arch is small, and we do not pay attention to it in the daily purchase and use. The effect is similar to our daily life that the earth is a sphere, but the earth we see has no arc for a reason.

The specifications of the tile firing process that cause uneven corners are not up to standard, the material is poor, and the tile is deformed during firing. This kind of brick is not only uneven, but also of different sizes, and must be adjusted by leaving joints when laying.

It is best not to choose, generally cheap tiles, ceramic tiles are prone to this kind of problem. Repair: If it is a tile quality problem, it is difficult to repair. If not, you can knock the bricks off and re-pave.

If it is hollow and the tile is loose, you can remove the brick, re-pave, or inject glue into the brick joint. If it is caused by no seams, it can only be re-paved. The uneven corners of the bricks caused by the quality problems of the floor tiles can be used to weaken the height deviation when paving, and the arch in the middle of the floor tiles after the four corners are leveled can try to pressurize with heavy objects until the cement mortar solidifies.

In the past, we used the topwood method to deal with uneven floor tiles, although the effect was okay, but it was very troublesome! What is the situation of a horizontal error of 10mm per meter? I can analyze it using the criteria for the horizontal error of the tile.

800 specifications of high-quality ceramic tile four-sided center level error, the enterprise internal control standard is less than or equal to, the national standard is. The internal control standard of the first-class product is less than or equal to, and the national standard is. If the tile is paved with a good joint, even if the level error standard of the first-class product is paved, it will feel very flat and the effect can be. With my 20 years of experience in the development of the ceramic tile industry, I rarely look at the tiles with more than the level error. The horizontal error reported by the owner actually went to 10mm, even compared with the worst tiles, it is several times different.

If there is such a large horizontal error, the tile force will also be uneven, and soon there will be bulging, cracking, hollowing, and then it is necessary to rework, and live in, more troublesome. By identifying the problem early, the rework loss is minimal.

There must be some quality problems, otherwise this will not be the case, and it is better to replace the uneven floor tiles with new ones, or use cement mortar to fill them.

The uneven floor tiles are not necessarily a problem of quality, and it may also be that the floor tiles are pasted after the ground itself is not leveled. It needs to be re-repaired.

The surface flatness of the floor tile is 2m, and the ruler is inspected 2mm

Floor tile hollowing: no more than 15% of the list, no more than 3% of the overall area

The flatness error of the floor tile itself should be within 2 mm, and the horizontal error of the floor tile should be within 3 mm after the completion of the paving.

There are two aspects to the flatness acceptance of floor tiles: one is the national standard for the flatness of the tile itself, and the other is the flatness construction standard after the floor tile is paved, I don't know which one you refer to. Let's explain these two separately:

a. National standard for the flatness of ceramic tiles. According to the requirements of the "GB4100-2006 National Standard for Ceramic Tiles", the flatness requirements of floor tiles are that the flatness deviation is less than and the maximum value is not more than 2mm. If the 600*600 specification of ceramic tiles is concerned, the deviation value of its flatness should be between to and the maximum value does not exceed the construction flatness requirements of the floor tiles.

According to the requirements of the "GB50209-2010 Code for Acceptance of Construction Quality of Building Ground Engineering", the flatness requirements of ceramic tile paving are measured by a two-meter ruler, the flatness deviation does not exceed 2mm, and the height difference of adjacent tile joints does not exceed that.

Summary. Extended Materials.

There are two aspects of the flatness acceptance of floor tiles: one is the national standard for the flatness of the tiles themselves, and the flatness requirements of the floor tiles are that the flatness deviation is less than and the maximum value is not more than 2mm. If you take the 600 by 600 size tile, that is, the deviation value of its flatness should be between to + and the maximum value should not exceed 2mm.

The second is the flatness construction standard after the floor tile paving, and the flatness requirements of the tile paving are measured by a two-meter ruler, and the flatness deviation does not exceed 2mm, and the height difference of the adjacent tile joints does not exceed that. The flatness of the national ceramic tile acceptance standard is the error of the first-level brick error is 13mm, and the flatness depends on the weight, the time of firing, and the size of the tile. The larger the tile area, the longer the manufacturing time, the heavier the quality, but the finished product is easier to deform, the cheaper the brick is lighter in quality, because the firing time is shorter, the better the flatness, but the hardness is poor, the thinner the glaze, the easier it is for dirty water to penetrate into the tile.

How much can the flatness of the national acceptance standard for floor tiles be incorrect.

Wait a minute, and you're sorting out the information for you.

The flatness error range of floor tiles is that the flatness deviation does not exceed 2mm, and the height difference of adjacent tile joints does not exceed that.

There are two aspects of the flatness acceptance of the extended data floor tile: one is the national standard for the flatness of the tile itself, and the flatness requirement of the floor tile is that the flatness deviation is less than and the maximum value is not more than 2mm. If you take the 600 by 600 size of the tile, that is, the flatness of the wild laughing difference value should be between to + and the maximum value should not exceed 2mm.

The second is the flatness construction standard after the floor tile paving, the flatness of the tile paving is required to be measured by a two-meter ruler, the flatness deviation does not exceed 2mm, and the height difference of the adjacent tile joints does not exceed that. The flatness of the national ceramic tile acceptance standard is the error of the first-level brick error is 13mm, and the flatness depends on the weight, the time of firing, and the size of the porcelain hail brick. The larger the tile area, the longer the manufacturing time, the heavier the quality, but the finished product is easier to deform, the cheaper the brick is lighter in quality, because the firing time is shorter, the better the flatness, but the hardness is poor, the thinner the glaze, the easier it is for dirty water to penetrate into the tile.
