Indoor paving suspended assembly floor has a sound solution

In all kinds of paving sites, there will always be different types of problems. What should I do when there is a sound in the interior of the pavement? Let's first analyze the cause of the sound of the assembled floor. Professionals point out that there are a number of reasons that can cause the prefabricated elastic flat wood look indoor sport flooring to make a sound. The so-called suspended floor sound is when people walk on the suspended floor, the suspended floor is up and down, and the floating floor lock or the tongue and the mouth are “frictionally” to produce a sound. The root cause is that the suspended floor and the ground create a “gap”. Among the current international standards, there are no technical indicators and test methods for floating floor sounds. Therefore, the sound of the suspended floor after installation does not indicate that there is a problem with the quality of the product. Suspended floor warping will also cause loud noises, but most of this situation will be discovered before paving. On the assumption that when the suspended floor is paved, the ground is not flat or the moisture is improperly handled, and the reserved seam is lacking, so that the asymmetric arrangement of the weight in the room may cause the suspended floor to make a sound. Solution: Beyond 8 meters, you need to make a partition Assuming that the ground is not flat, the moisture-proof disposal is not in place, and other factors, the large area of ​​the house without the partition treatment will also cause the ground to make a sound. In rooms with a length or width greater than 8 meters, the total shrinkage of the prefabricated interlocking indoor tennis court is three thousandths, that is, the shirring is 24 mm, and a gap of 12 mm should be left on both sides of the wall. But the baseboard is only 10 mm, and only 8-9 mm of the seam can be retained to buckle. Assuming that there is no partition treatment, there must be a problem of the suspended floor arching. Even if there are enough gaps, it will be bulged, causing the stepping on the suspended floor to move up and down, causing the sound to collapse. In this case, the maintenance is very laborious and the whole has to be removed. The partition is to "add a buckle" to change the direction of the suspension floor. In addition to the partition, the gap must be reserved according to the shrinkage rate of the suspended assembled floor. It is understood that the suspended floor will be irregularly contracted from the center of each room to the periphery, the center position does not shrink, and the farther away from the center line, the greater the amount of contraction. Therefore, even if the total room length and total width do not exceed 8 meters, the contraction direction should be designed. The center line of the outermost contour of the whole room should be taken as the center line, and then the reserved gap of each side position should be calculated according to the distance and contraction amount of each side from the center line, and the contraction direction of the prefabricated interlocking running track is artificially set.
