Is it better to make a double layer or a single layer of wooden floor keel

Single-layer keel structure.

Double-layer keel structure.

The concept of single-layer keel and double-layer keel, it can be literally concluded that the double-layer keel and the single-layer keel have one more layer of keel, and the double-layer keel is cross-paved, whether it is a single layer or a double layer, the standard spacing is 400mm.

Professionalism: The double-layer keel is more professional than the single-layer keel, the double-layer keel is mainly used for the basketball wooden floor of the professional competition venue, and the double-layer keel has higher requirements for the ground. The single-layer keel is used for basketball training, badminton, activity centers and other sports wood flooring venues.

Cost: Double-layer keel is 10% higher per square meter than single-layer keel**.

Basketball court sports wood flooring** is affected by a variety of conditions, such as main materials, auxiliary materials, venue area, etc. Professional sports wood flooring** is between 600-1500 yuan square meters, and non-professional general-purpose sports wood flooring is between 300-450 yuan square meters.

The sports wood floor of the basketball court has strong deformation resistance and shock absorption performance, not only that, the moisture-proof film on the surface of the sports wood floor also allows this kind of wood floor to be eroded by water and moisture during use, and brings a comfortable bouncing feeling to the user on top of the high elastic performance; Not only that, when the sports wood floor is installed, the elastic rubber mat is used to increase the efficiency, and the overall load capacity of the sports wood floor is improved. For those areas where the use is more secret, such as the third area of the basketball court floor, it is necessary to use at least 9-12 shock-absorbing pads per square meter to improve the shock-absorbing performance of the floor.

Things to look out for:

In the construction of most stadiums, there are often changes in the design and change of the construction plan due to the sports wood flooring, resulting in additional investment and even affecting the construction period. For example, people's understanding of sports wood flooring often stays at the level of the era, one-sidedly thinking that the thicker the sports wood floor, the better, the stronger the better, and ignoring the sports function and protection function that sports wood flooring should have. Therefore, when designing the floor of the gymnasium, it is necessary to communicate and coordinate with the manufacturer, clarify the standards, and avoid the problem of unnecessary presence.

Now the environmental protection used by people is mainly reflected in its production materials, the raw materials of sports wood flooring are mainly made of solid wood, so that the material has the characteristics of green environmental protection and non-toxic, so it is not harmful to our health, and this material can also be used in our daily life, and it is also recognized by colleagues in the testing unit, so it will not produce some gases harmful to our body in use, nor will it cause some safety hazards in our body. This aspect is mainly said that the sound absorption of the sports floor reduces the function of noise, when the athletes will have some sound when jumping, if the floor is not sound absorption at this time, it will cause a lot of people to have a lot of noise at the same time, which will also affect some training and competition between the athletes, so in order to make the environment noiseless, can provide a good environment for athletes, this special floor also has this aspect of environmental protection.

1. Sports performance.

Due to the different internal structures of the single-layer keel structure system and the double-layer keel structure system, their motion performance is also different. The stability of the double-layer keel structure system is much stronger than that of the double-layer keel structure system.

Solid wood sports flooring.

2. Procurement**.

The keel of the single-layer keel structure system occupies relatively small space because there is only one layer, and the construction difficulty is small, and the project cost is low. In addition, the internal composition of the double-layer keel structure system is a double-layer keel, which occupies a relatively large space and is difficult to construct. Now with the double-layer keel system, the production process is more complicated.

Therefore, the purchase of a double keel system is higher than that of a single keel system.

3. Paving the venue.

The cost of the single-layer keel structure is much cheaper, and it is suitable for private venues or small and medium-sized competition venues, where the amount of movement and exercise intensity are relatively small; The double-layer keel is suitable for venues that have held top international events for a long time.

Generally, it is a single layer, unless it is a last resort.

Generally, if the ground level is standard, it is a layer, as long as it is installed and fixed firmly, the use effect is the same. Generally, a 3*5 keel will be selected, and the floor will be less than 5 cm, so that the possibility of deformation is very small. It will not affect the height of the whole house, and it will not cause unnecessary waste.

In addition, the horizontal error of some houses is relatively large, and it is generally necessary to use a layer of keel to achieve the same level of more than 2 cm, and a double keel should be done in a low place, but it is necessary to use an elongated Meigu nail to achieve a firm effect, and the specifications of the keel should be large enough, not less than 3 * 5.

Three-layer solid wood flooring or multi-layer solid wood flooring, do you need to tie the keel for laying?

Pro, three-layer solid wood flooring or multi-layer solid wood flooring, laying does not need to hit the keel. You can use the keel, three-layer solid wood or multi-layer solid wood, reinforced compound, can be laid directly on the ground, but you need to pay attention to a flatness of the ground, the height error within 1 meter does not exceed 2 mm, you can. Multi-layer parquet does not need to be tied at all.

Because the parquet (which is mainly made of solid wood composite made of multi-layer solid wood veneer, the precise category name "solid wood multi-layer floor") is stable. Of course, there are also certain benefits to playing keel, and the foot feeling will be better. To hit the keel, you need to make a blockboard (you said the wool floor).

However, there are certain disadvantages, the parquet is stable and not easy to deform. But keels and blockboards are hard to say. It is often that there is a problem with the keel and blockboard, which causes the ground to be uneven and noisy.

Hello! I am glad to answer for you, the three-layer composite floor needs to play keel 1, and it is necessary to play and code the keel, because the moisture-proof performance of the floor of this material is not particularly good, and the material is relatively fragile and easy to be affected by the surrounding environment. However, after the bone is beaten, the parquet is raised away from the ground, which plays a role in moisture and waterproofing, and will not be affected.

2. At the same time, after hitting the keel, it can also make the ground more flat, which is equivalent to leveling, and then lay the parquet on the surface, which brings more convenience to the later installation of the floor. 3. There is a difference between the keel floor and the molded floor without keel, that is, it is not easy to drum and crack, and it is not easy to make a squeaky sound when stepping on it, and the service life is longer.

Summary. Laying wooden floors can also be done without keel, but it is still necessary to carry out ground leveling, and now home decoration and laying wooden floors are popular to do self-leveling for ground leveling. As an innovative ground construction technology, the whole process does not rely on manual scraping, as long as the liquid floor paint is spread to the ground and then flows automatically, the low-lying area is automatically found on the ground and filled in, and finally the whole ground flows into a mirror-like flat after stationary, and after condensation and solidification, a smooth, flat and seamless ground can be formed.

Is it okay to lay the second floor of the wooden floor without a keel?

Laying wooden floors can also be done without keel, but it is still necessary to carry out ground leveling, and now home decoration and laying wooden floors are popular to do self-leveling for ground leveling. As an innovative ground construction technology, the whole process does not rely on manual scraping, as long as the liquid floor paint is spread to the ground and then flows automatically, the low-lying area is automatically found on the ground and filled in, and finally the whole ground flows into a mirror-like flat after stationary, and after condensation and solidification, a smooth, flat and seamless ground can be formed.

Solid wood floors need to be keeled. Solid wood flooring is made of natural wood species, so it has the characteristics of wood itself, and wood fibers are arranged in one direction with single fibers. Therefore, deformation and bending will occur naturally after preparation and processing.

Therefore, it is necessary to use the wooden keel tic-tac-toe laying, and fix the solid wood floor on the wooden keel with special floor nails to prevent the deformation of the solid wood floor to the greatest extent (of course, there is no need to hit the keel when the rise of the solid wood lock floor, including the current mature technology can control the wood properties, and the solid wood floor of the ordinary flat groove can also be directly laid on the ground in the case of ground leveling, which has been widely used in many areas). Laminate flooring and parquet flooring do not have to be keeled. Generally, these two kinds of floors do not need to be keeled, and the floor can be done.

To hit the keel. Solid wood flooring is a single fiber direction arranged in the direction of wood, wood, that is, easy to deform, so paving solid wood flooring, it is best to frame the keel, with the keel to fix it, so that it is not easy to deform. As long as the floor is not pure solid wood, it is not necessary to use the keel to install.

The wooden keel must be made of dried wooden squares (moisture content.

less than 16%) and keel special screws.

fixed, but pay attention to the moisture content of the keel can not be too low, around 14% as well.

If you want to put large furniture such as wardrobes in the house, it is best not to hit the keel, the cabinet will deform the floor, and the cabinet door will also be deformed, it is recommended to level the ground first, and then directly lay the floor. But if the environment is more humid, it is better to play keel.

The function of the keel is mainly to stabilize the structure of the solid wood floor, and the direction of the paving keel is perpendicular to the direction of the floor, the purpose is to stagger the constraints and prevent expansion and contraction. In the early days, the pavement of solid wood floors basically required keels, because the solid wood floor pure wood structure was susceptible to the influence of the environment and bulging and shrinking. The keel cannot be installed in a room with underfloor heating, and the keel pavement sometimes has the problem of floor noise.

Now many three-layer solid wood floors can be installed tilly, and some have patented lock technology, so that the floor will not be retractable and deformed, such as the Shengxiang Kangyi series, when installing, only the two floors need to be aligned up and down, and they can be precisely buckled, and the real tight seams can avoid dust accumulation and bacterial breeding. There is no need for the complicated keel treatment of traditional solid wood flooring, which is convenient and fast, labor-saving and time-saving.

Multi-layer solid wood flooring is generally to lay keel, generally multi-layer solid wood flooring after the keel, the foot feels comfortable and more durable. It's just that the cost of multi-layer solid wood flooring is more expensive than other installation methods. However, the multi-layer solid wood floor can also not be paved keel, because the solid wood floor is a wooden object arranged in a single fiber direction, so there will be wood, that is, the club will be deformed, so use the keel to fix it so that it is not easy to deform.

The most important point is that it can play a good role in moisture protection. Therefore, whether the installation of multi-layer solid wood flooring is keeled depends on each family's own situation.

Solid wood parquet needs to play keel, the most important thing is to level the ground, because the cement ground is not very flat, if there is no leveling, the difference of 4,5 cm, there is also a keel to prevent moisture, can extend the service life of the floor, and the keel in order to reduce dryness, when people walk on it, they will feel much milder, and there is no noise. Now they are all nailed to the floor, and the floor is nailed to the nine-centimeter board above the keel.

The laying of parquet is not complicated, and there are many ways, including keel pavement, suspension pavement, direct paste, etc. Generally, it is necessary to first determine that the flatness of the ground meets the requirements, and then start to clean the ground, clean the dust, gravel, etc., and then lay it.

Advantages and disadvantages of playing keel:

Advantages: Leveling the ground: The most important thing to play keel is to level the ground, because the cement ground is not very flat, if there is no leveling, the difference of 4 or 5 cm is there.

Moisture-proof: In order to prevent moisture, the service life of the floor can be extended.

Easy to install: Because the floor is now nailed, the floor is nailed to the nine-centimeter board above the keel.

Noise reduction: Fourth, it is to reduce dryness, when people walk on it, they will feel much gentler, and there is no noise.

Disadvantages: Abnormal noise: If the keel on the market is not dry, the keel is easy to shrink after a long time after paving, so that the floor is easy to make abnormal noise.

Perishable: Keels can be very perishable if not treated well.

The process is complicated: the process of beating the keel is very complicated, and it is necessary to destroy the ground, so that the structure of the house changes, and the safety factor is reduced.

Reduced space: After the keel is played, the ground will be raised and the space used in the house will be reduced.

Disposable: The floor cannot be reused after the keel is installed.

It is recommended to be stunned, and the general store is responsible for the floor, otherwise there will be a sound when walking for a long time.

Parquet installation is the same as laminate flooring, no keel is hit, just leveling.

The wooden keel of the floor paving is for waterproof and moisture-proof, otherwise the floor is in direct contact with the floor slab and is easy to rot. Then there is the ability to use the keel to adjust the height difference. In addition, it is convenient for construction, if the floor is directly done on the foundation, then the requirements for the foundation are quite strict, the foundation must be made quite flat, otherwise it is not convenient to install, and it is directly installed on the foundation, and the expansion screw needs to be fixed, which is not conducive to the appearance.

Parquet is a floor decoration material formed by drying and processing wood. The base material of the parquet is made of multi-layer veneer, and the wood fibers are crisscrossed into a network of stacking combinations, so that the various internal stresses of the wood are adapted to each other between the laminates, ensuring the flatness and stability of the wood floor, and to a certain extent, overcoming the shortcomings of the wet expansion and shrinkage of the solid wood floor, the dry shrinkage and wet expansion rate is small, and it has good dimensional stability. It is installed in a floating method, so there is no need to beat the keel.
