Floor tile paving acceptance specifications, floor tile paving national acceptance standards

There is little difference with the wall installation, 1. Look at the seam 2, the flatness, the four corners of the block do not block the hand, 3. The hollow drum floor tiles are not allowed to have hollow drums, 4. Whether the surface texture meets the design requirements.

The four corners are flat, and there are no empty drums.

1. The surface of the brick surface layer should be clean, the pattern should be clear, the color should be consistent, the joints should be smooth, the depth should be consistent, and the perimeter should be straight. The plate should be free of defects such as cracks, corners or missing edges.

2. The trimming materials and sizes adjacent to the surface layer of the floor tiles should meet the design requirements, and the corners should be neat and smooth. Inspection method: inspection by observation and steel ruler.

3. The surface of the baseboard should be clean, and the combination with the column and wall should be firm. The height of the baseboard and the thickness of the column and wall should meet the design requirements and be uniform. Inspection method: inspection by observation, small hammer and steel ruler.

4. The slope of the floor tile surface layer should meet the design requirements, and there should be no flooding and no stagnant water; It is tightly combined with the floor drain pipeline and has no leakage. Inspection method: observation, splashing water or checking with a slope ruler and water storage.

5. The hollow drum rate of the tile: the combination (bonding) of the tile surface layer and the next layer should be firm, and there should be no hollow drum (a single brick is allowed to have local corner hollow drums, but the hollow drum bricks in each natural or standard room should not exceed 5% of the total number of paving), and the inspection method is to use 25g drum mallets to knock on the brick surface for inspection.

What are the precautions for tile paving acceptance?

1. See whether the original foundation treatment is in place before paving. The base should be chiseled, the depth of the chisel is 5 10 mm, the spacing of the chisel marks is 30 mm, the left rubber hole nucleus right. According to the requirements of the construction process, if there is putty on the original wall before pasting the wall tiles, the putty should be removed, and then the smooth plastering layer will be chiseled and the surface should be cleaned, and then the brushing should be carried out with plain ash, and finally the tiles should be pasted.

Otherwise, the bond between the tiles and the base layer is not firm, which leads to the hollowing and delamination of the wall tiles.

2. See whether the cement mortar on the back of the tile is full. The mortar behind the tiles should be full to ensure that the corners are not hollow. According to the regulations, when the wall tiles are paved, the mortar should be full and firmly pasted, and the hollow drums of a single corner of the wall shall not exceed 5% of the number of paving.

When laying bricks, it is advisable to use 1:2 cement mortar, the thickness of which should be 6 to 10 mm, and then gently compacted with a rubber hammer, otherwise it is easy to appear hollow.

3. Look at whether the tiles have color difference. The two adjacent wall tiles showed obvious color differences. According to the relevant regulations, the variety, specification, grade, color and pattern of wall tiles should meet the design requirements. After paving, the color of the tile should be basically the same, no obvious color difference, clean and free of material volume and slurry marks.

4. Look at the corners of the tiles (yin and yang corners) because they are not treated well, and the tiles at the yang corners are cracked. Workers usually use it as the skeleton of the riser of the kitchen and bathroom package, paste the cement pressure plate outside, and then hang the metal mesh. After tiling, due to the different physical expansion coefficients of light steel keel and cement, the skeleton is easy to deform, and the possibility of cracking at the corner of the wall tile is greater.

It is recommended that the owner of the kitchen and bathroom package riser should be based on lightweight bricks.

5. See if there are small strips on the wall tiles. The size of the innermost mosaic of the wall is obviously small, and the size of the ruler beam should be calculated in advance, and the amount of trembling should be discharged to the place where it is not obvious. According to the regulations, the pay-off positioning and brick arrangement should be carried out before brick laying, and the non-whole bricks should be arranged to the secondary part or the yin corner.

There should not be two columns of non-whole bricks on each wall, and the width of the non-whole bricks should not be less than one-third of the whole brick.

Many families will choose to pave floor tiles on the floor of the living room, bathroom and kitchen, and the floor tiles need to be accepted after being pasted, and they can only be used after confirming that there is no problem, so what is the national acceptance standard for floor tile paving? Let's learn about Changhui Closure together.

1. Hollow drum rate: The combination of the tile surface layer and the wall layer should be firm, and there should be no hollow drum. However, the local corners of a single brick are allowed to have hollow drums, but the hollow drum bricks in each natural or standard room can not exceed 5% of the total number of paving, and you can use a 25g drum hammer to hit the surface of the tile to check whether the tile is hollow.

If there is a hollow drum in the middle of the floor tiles, then it is not allowed, especially in the aisle, at this time, the floor tiles must be warped and then re-paved.

2. Flatness: The surface of the floor tiles should be clean, the pattern should be clear, the color should be consistent, the joints between the floor tiles should be smooth, the depth should be consistent, and the surrounding area should be straight. The floor tiles should have no cracks, falling corners or missing edges.

You can use a 2-meter ruler to measure the flatness of the floor tiles, place the ruler on the floor tiles, and then see if there is a gap between the ruler and the ground, generally speaking, it can not be exceeded.

3. Measure the level: you can use a 2-meter ruler to measure the level of the floor tiles, and there is a level above the ruler, and you can see whether the floor tiles are level through the balance of the water droplets of the level.

4. Yin and Yang angle deviation: As long as there is no problem with the levelness of the floor tiles, then the Yin and Yang angles generally do not have any problems. If the deviation of the yin and yang angles is too large, then it needs to be made up.

5. Gap width: The gap width of the floor tile has a certain relationship with the type of tiling, and it cannot exceed 2mm under normal circumstances. And the width of the gap of the floor tiles must be consistent, and too much deviation is not allowed.

6, hollow drum remedy: floor tiles appear hollow drum is inevitable, if there is a deterioration of the hollow drum, then you can make up for the hollow drum part of the floor tile by the method of gap grouting method, if the floor tile appears a large area of hollow drum phenomenon, then it must be re-paved.

7. Slope of floor tiles: The slope of the surface of floor tiles should meet the design requirements, should not pour flooding, no water accumulation, and should be tightly combined with the floor drain pipeline, no leakage. You can observe, splash water or use slope gauge and water storage to check whether the crack resistance of the floor tile slope is qualified.

The above is a detailed introduction to what the national acceptance standards for floor tile paving are, and I hope it can help all friends in need. It is inevitable that the floor tile will be hollow, if there is a deterioration of the hollow, then the hollow part of the floor tile can be made up by the method of gap grouting or it must be re-paved.
