To make the floor soundless, it is necessary to first find out the reason for the sound of the floor. In general, the reasons for the floor noise are as follows: 1Sound caused by uneven ground 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. 2 wooden keel is too far away The distance of the wooden keel should not be too far away, 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. 3 Wooden keels have a large difference in moisture 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. 4 Inappropriate moisture prevention measures 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, after stepping on a few feet will not ring, and after a while will step on this place will ring, which is why? In fact, it is very simple. When we step on the same place several times, the floor has been in close contact with the wooden keel. There is no room for the floor to move up and down, 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. 5 reserved gap is insufficient Solid wood floor has the characteristics of shrinking and swelling. When installing the floor, the gap between the floorboards must be properly reserved according to the actual moisture content of the floor, the shrinkage coefficient of the wood, and the equilibrium moisture content of the area. If there is insufficient space between the floor bars when the floor is installed, the floor will be slightly squeezed, the individual places will be slightly raised and a gap will be created between the floor and the wooden keel or cushion, and the person will walk on the floor to generate a sound. According to the specification of wood floor covering, acceptance and use (GB/T20238-2006), when the solid wood floor is installed, a cushion layer is laid on the wooden keel, and a moisture-proof film is laid on the top of the cushion, which can effectively control the influence of the external environment on the floor. , to prevent the floor tile deformation. The mat is usually made of a wool floor or a wood-based panel. Many installers use a plywood or blockboard as a mat. The whole piece of joinery or plywood is placed on top of the wooden keel without gaps between the mats. The floor plays a drum, causing the floor to pick up a drum and producing a sound. The cushion under the floor should be cut 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 put a damp-proof film on the top of the cushion, install the floor above the damp-proof film, and reserve the gap scientifically and reasonably. It can solve most of the noise. In summary, a variety of reasons can cause floor noise. In order to avoid the appearance of noise, we must choose the correct installation method, do a good job of moisture-proof floor treatment, reasonable reserved gaps, to provide consumers with proper use and maintenance methods. Once the sound of the floor is difficult to handle, it is very important to take active preventive measures. Find out the reason for remedy.
