Didn't the sound of your home's wooden floor step on it? To make the floor soundless, we must first find out the reason why the floor makes a sound. Today Xiao Bian sums up the following points for everyone, so come and learn.
Zexi parquet
According to the specification of wood floor covering, acceptance and use (GB/T20238-2006), the flatness of the ground is ≤ 5mm/2m, and the flatness after installing the wooden keel is ≤ 3mm/2m, and the actual ground flatness is difficult to meet the requirements. The installers had to add gaskets underneath the wooden keel. Some of the washers were not cushioned or flat. After the floor was installed, parts of the floor were not completely in contact with the wooden keel, and people squeaked when walking on the floor. This situation occurs immediately after installation and is partial.
1. The distance between wooden keels should not be too far away, and do not exceed 350mm. Some wooden keels have a distance of 450mm or more. When a person with a heavier weight walks on a single floor, the floor has a greater deflection. The floor side rubs against the adjacent floor and generates a sound. . If it is for this reason, as long as you step on a single floor, it will ring, and if you step on multiple floors, it will not ring, and it will happen after installation.
2. The wood keel has a large difference in water content
In some areas, wood keels are not dried and stacked in the open air. The moisture content of wood keels differs greatly. In the same batch of wood keel, some moisture content is about 10%, and some are as high as 25% or more. Even if the installer finds the wood keel to be flat, the floor may not ring for a while after installation. In the course of use, the moisture content of the wooden keel is rebalanced, and unevenness will appear. Walking around the floor will produce a loud noise. Features are: No sound during installation, sounds after a period of use. There are not many sound zones. The wood keel used in large brands in Beijing should be dried, and some dealers should use the wood keel, and do not install the floor for a short time. After a week or so, re-leveling and paving can reduce the probability of such problems.
3, improper measures against moisture
When the floor is installed, due to improper moisture prevention measures, the floor will be deformed after being damped, and the floor will not produce noise when the tile-like deformation is serious. Because the floor is over-expanded and squeezed tightly, people walk on the floor. The floor will not move up and down, so it will not produce mutual friction and noise. Consumers mainly complained about floor deformation or board cracking. If the floor water runs out, the floor water continues to fall to normal, there is a gap between the floor, the floor tile has not completely disappeared, the tile-like floor above the wooden keel like a seesaw, people on the floor When you move around, you will feel the sound everywhere.
This situation first experienced a wet period and then entered the dry period before it occurred, mostly in the northern winter. In addition, there is a more special situation. In the floor installation process, although the moisture prevention is not done well, because the ground water is not very high, the floor appears a slight bulge and a slight deformation of the tile, and even the visually no sense Drums and tile-like deformations that the floor has already produced. In fact, there is a slight gap between the floor and the wooden keel. When people step on the floor, they will make a noise. The characteristic of this kind of problem is that the sound will be generated in a short time after the floor is installed, and more and more, more and more heavy. The shortest time will ring on the next day of installation. Some people often ask: Stepping on the same floor, the first foot will ring, and after stepping on a few feet, it will not ring. After a while, it will ring again. Why is this? In fact, it is very simple. In the same place, the floor has been in close contact with the wooden keel. The floor has no space for up and down movement and the floor will not ring. When we stepped on other places, the floor was raised again and there was a gap with the wooden keel. So, once again, this place will produce a sound.
