Solid wood floor swells "very personal" installation seams can not be "one size fits all"
According to many floor practitioners, whether they are dispatched by merchants or owners to find "roadside workers" to install themselves, these workers will generally leave a packing belt or playing cards between the boards to pack or play cards. The thickness serves as a standard for the gap between the plates. There are also many workers who are engaged in floor installations for many years, and basically rely on visual inspection and experience to control the gap between the board and the board. It is reported that the size of the national standard gap between the board and the board is "less than or equal to 0.8mm", and the thickness of the currently used packaging belt is generally about 0.6mm, the thickness is about 1mm, and the thickness of the playing card is 0.6mm. about.
That is to say, if the worker uses a thicker package to use as a seaming tool for laying the floor, it is easy to exceed the national standard, which leads to the arching of the floor. The use of visual gaps to lay the floor is more prone to problems. After all, the gap of the national standard of less than 1mm is difficult to judge with the naked eye.
The person in charge of the Yating Meiju Building Materials Supermarket, which represents many well-known flooring brands, pointed out that even more worrying is that even if the paving seams meet the national standard, there is no guarantee that the floor will not be deformed. In fact, the materials of different tree species are different, the ability to absorb or release water is different, and the cycle of "health" (the process of adjusting the moisture content of the floor) in the factory is different, resulting in different brands and different tree species. The degree of floor swell is not the same, so the gap between the board and the board should be subtly different when paving. Therefore, the rough floor installation method that is popular in the market is very likely to cause deformation of the floor.
The famous netizen "Chinese soul"--Chen Zengyong, the relevant person in charge of the supervision office, analyzed that the main reason for this situation is the gap between the floor and the wall and the gap between the board and the board during the installation operation. Improper size control, resulting in the floor when the rainy season is inflated, there is not enough elastic expansion space, and finally the floor is squeezed and arched. In the winter, the solid wood floor is contracted by cold, and an excessive gap is formed between the board and the board. At this time, the floor lacks a force point and will warp in the case of rapid drying. It can be said that everything is the fault of the gap size!
To determine the extent of floor swell, the moisture content of the floor must be determined.
Yu Feng, the general manager of the Fujian Provincial Flooring Industry Association, is the general manager of Xintongfu Wood Industry. The ability to absorb or release water, the floor "health" cycle and other factors affecting the degree of floor swell can be concluded in a certain sense. For the problem of floor moisture content.
It is understood that after the trees have been cut down to make solid wood flooring, although there is no oxygen-making function, there are characteristics of adjusting the humidity and temperature of the indoor air. In order to find its own equilibrium moisture content, wood will absorb or release moisture in response to changes in the moisture content of the surrounding air. The moisture content of the floor varies according to the characteristics of the tree species, and the geographical location is different and different. In the case that the characteristics of the tree cannot be changed, reasonable "health", so that the moisture content of the solid wood floor is consistent with the local average water content, becomes the key to ensure the stability of the floor moisture content.
According to national regulations, the moisture content of the floor is 8%-12% qualified, higher in the south and lower in the north. There are different standards in all places. The average water content of Fuzhou solid wood flooring is between 10% and 12%. It is understood that many well-known flooring brands outside Fujian Province have set up "health rooms" that simulate the geographical environment of each province, ensuring that the moisture content of the floor is suitable for the needs of Fujian owners, while the local manufacturers in Fuzhou are here. It has the unique advantage of being able to "preserve" a floor with a stable moisture content in the most authentic local geographical environment. When purchasing, the consumer can consult with a professional salesperson, or use the "water content detector" to check the moisture content of the wooden floor of the purchased product after unpacking, in order to purchase a floor with a water content equal to the local average moisture content.
The moisture content of the floor can be installed with the subtle changes in the season.
The average water content of Fuzhou solid wood flooring is between 10% and 12%. According to this data, the gap between the board and the board should be between 0.3mm and 0.8mm. In the case of a stable water content, the 'health' season of the floor is not the same as the installation season, and it also has a subtle effect on the moisture content. In order to make the floor in the future, it is necessary to make a more detailed separation of the standard interval of the seam.
Shao Jifang, the captain of the installation of Haolinju floor, told the reporter about the installation of the solid wood floor of the "disc bean" tree in Fuzhou. If it is a winter solidarity and winter installed solid wood floor, the gap between the board and the board should be 0.5- 0.8mm, because the moisture content of the floor in winter is low, the floor installed in winter is affected by the low temperature and shrinks, so the gap is relatively large when installing; if it is the rainy season, when it is winter, the gap is left. It will be slightly smaller, almost between 0.3-0.5mm; during the rainy season, the floor installed in the rainy season generally does not need to leave a gap, otherwise the floor will shrink in winter, and the gap will affect the appearance.
"Three-point floor, seven-point installation" has become a recognized view in the industry. The person in charge of Wanxin Decoration and the decoration of the famous craftsmen also said that in the past three years, the owners basically required the floor supplier to provide installation and paving services. Because the floor installation requires professionalism, the installer must have a good understanding of the tree species, moisture content, and health period of the floor. The famous brand or local brand of the province, the installation workers also know more about the moisture content and the health period of the product, and the control of the gap between the board and the board is more reasonable during the installation process.
