If you want to make the floor soundless, you must first find out the reason why the floor makes a sound. Generally speaking, the reason why the floor has a sound is as follows:
1 The sound caused by uneven ground is in accordance with the specifications for paving, acceptance and use of wooden floors (GB/T20238-2006). The flatness of the ground is ≤5mm/2m, and the flatness after installing the wooden keel is ≤3mm/2m, the actual ground. The flatness is difficult to meet the requirements. The installer has to add a gasket under the wooden keel. Some of the gaskets are not padded or not leveled. After the floor is installed, some parts of the floor are not completely in contact with the wooden keel. People walk on the floor. When the sound is heard. This situation will be heard immediately after installation and is partial.
2 The distance of the wooden keel is too far. The distance of the wooden keel should not be too far, generally not more than 350mm. Some wooden keels are at a distance of 450mm or farther. When a person with a heavy weight steps on a single floor, the floor has a large deflection downward, and the side of the floor rubs against the adjacent floor, causing a sound. . If this is the case, 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.
3 The moisture content of the wooden keel is quite different. In some areas, the wooden keel is not dried, and it is randomly placed in the open air. The moisture content of the wooden keel is quite different. Among the same batch of wooden keels, some have a moisture content of about 10%, and some have a moisture content of more than 25%. Even if the installer finds the wooden keel very flat, the floor may not be loud after installation. During the use, the moisture content of the wooden keel will be rebalanced, and there will be unevenness. When walking on the floor, it will produce a sound. The characteristic is: it does not ring when installed, and it will ring after a period of use. There are not many sound areas. Therefore, the wooden keels used by the big brands in Beijing must be dried. Some dealers have finished the wooden keel and temporarily do not install the floor. After a week or so, re-leveling and re-paving, the probability of such problems can be reduced. .
4 Moisture-proof measures When the panel is not installed, due to improper moisture-proof measures, the floor will be deformed after the damp. When the tile-shaped deformation is serious, the floor will not produce a sound, because the floor is over-expanded and squeezed tightly. Walking on the floor, the floor will not move up and down, so there will be no mutual friction and noise. At this point, the main complaint from consumers is that the floor is deformed or the board is cracked. If the moisture on the ground runs, the moisture of the floor continues to drop to a normal state, and there is a gap between the floors. The tile of the floor has not completely disappeared. The tile-like floor is like a seesaw on the wooden keel. People are on the floor. When you walk, you will feel everywhere. This situation occurs first in a wet period and then in the dry period before it occurs, mostly in the winter in the north. In addition, there is a special case. During the installation of the floor, although the moisture is not well done, because the moisture on the floor is not very high, the floor has a slight bulge and slight tile deformation, and even the visual sense is not felt. The bulge and tile deformation that the floor has produced. In fact, there is a slight gap between the floor and the wooden keel, and when people step on the floor, it will produce a sound. The characteristic of this type of problem is that the sound will be generated in a short time after the installation of the floor, and more and more and more and more heavy. The shortest time will ring the next day of installation. Some people often ask: When you step on the same floor, the first foot will ring, and after a few feet, it will not ring. After a while, it will ring again. Why? In fact, it is very simple. When we step on the same place many times, 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 here was raised again, and there was a gap with the wooden keel, so stepping on this place again would produce a sound.
5 reserved gaps are not enough for solid wood flooring to shrink and swell. When installing the floor, the gap between the floor strips should be reasonably reserved according to the actual moisture content of the floor, the shrinkage factor of the wood, and the equilibrium moisture content of the area. If the reserved gap between the floor strips is insufficient when the floor is installed, the floor is slightly squeezed, the individual places are slightly raised, and there is a gap between the floor and the wooden keel or cushion, and the person walking on the floor produces a sound. According to the specifications of wooden floor paving, acceptance and use (GB/T20238-2006), when the solid wood floor is installed, the layer is layered on the wooden keel, and the moisture-proof film is placed on the cushion layer, which can effectively control the influence of the external environment on the floor. To prevent the deformation of the floor. The cushion is usually made of wool floor or wood-based panel. Many installers use the plywood or blockboard to make the cushion. The whole piece will be placed on the wooden keel with the joinery or plywood, and there is no gap between the cushions. After damp. The cushions act as drums, causing the floor to bulge and also produce a sound.
Therefore, the cushion under the floor should be sawed to a size of not more than 600 × 600 mm, and a gap of not less than 5 mm should be left between each cushion. Then, a moisture-proof film is placed on the cushion layer, a floor is installed on the moisture-proof membrane, and a gap is scientifically and reasonably reserved. It can solve most of the sounds.
In summary, a variety of reasons can cause the floor to produce a sound. In order to avoid the appearance of noise, we must choose the correct installation method, do a good job of moisture-proof treatment of the floor, and reasonably reserve gaps to provide consumers with proper maintenance methods. It is very difficult to deal with the sound of the floor, so it is very important to take positive precautions. Find out the reason for the next symptom.
