What is the difference between a single layer keel and a double layer keel for solid wood sports flo

1. Installation sequence.

The installation sequence of the single-layer keel structure (from bottom to top) is: leveling cushion block - elastic cushion - wooden keel - wool floor - moisture-proof film - surface floor.

The installation sequence of the double-layer keel structure (from bottom to top) is: leveling cushion block - bottom wooden keel (main keel) - elastic pad - upper wooden keel - raw floor - moisture barrier layer - surface floor.

Single-layer keel structure sports wood flooring.

2. Structural advantages.

It can be seen from the installation structure that the double-layer keel structure adds a layer of keel between the wool floor and the elastic pad, and the overall height of the sports wood floor increases, which increases the distance between the wool floor and the ground, so that the bottom structure of the wood floor has better ventilation and better moisture-proof function.

3. Differences in performance.

The main reason why sports wood flooring can provide a good sports experience is its structure. Compared with the single-layer keel structure, the double-layer keel structure has better cushioning performance, and is better than the single-layer keel structure in terms of vibration absorption and resilience.

Double-layer keel structure sports wood flooring.

4. Price. The double-layer keel adds a layer of keel and other auxiliary materials to the structure, which also increases the amount of construction, so it is slightly higher than the single-layer keel structure in terms of price.

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.

Gymnasium wooden floors.

2. Purchase price.

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 price 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.

Comparison of sports performance: In terms of sports performance alone, the single-layer keel and the double-layer keel are in line with the corresponding standards of the German DIN, and the double keel is not much stronger than the single keel in actual use, unless the venue holds the international top events for a long time, and the single-layer keel structure of the regular event venue is enough to deal with it.

Comparison of project cost: because there is only one layer of single-layer keel, it occupies relatively small space, and the construction difficulty is small, and the project cost is low, which is cost-effective. Compared with the double-layer keel structure, the cost of the single-layer keel structure is much cheaper, which 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.

Comparison of construction difficulty: due to the addition of a keel layer and elastic rubber cushion layer, the overall project is much more difficult, the cost is higher than that of a single keel, and the later maintenance cost is also higher.

Scope of application: The two keel structures are also suitable for basketball halls, badminton halls, volleyball halls, stages, theaters and other venues.

It should be noted that the type, origin, thickness and performance of sports wood flooring panels are different, so before purchasing sports wood flooring and supporting structural systems, we must do a good job of investigation and understanding of relevant aspects, and choose plates, structural systems, construction processes, etc. suitable for the needs of their own venues according to their needs, so as to ensure higher cost performance.

1. Compared with the single-layer keel structure, the internal space of the double-layer wooden keel is relatively large, and the performance is better, so the area of the brushed anti-corrosion material is relatively more, anti-corrosion and moisture-proof, and the structure of the entire stadium floor is naturally more stable.

2. The sports floor with double-layer keel structure can increase the thickness of the floor and increase its adjustable thickness, which is more effective for adjusting the flatness of the stadium floor.

3. The double-layer keel can better and more efficiently transmit the vibration pressure from above to the ground, combined with the wood toughness of the double-layer keel itself, thereby increasing the stability of the entire gymnasium sports wood floor, so that the service life of the gymnasium is longer.

4. Single-layer keel and double-layer keel sports wood flooring are suitable for different types of stadiums, users should locate the type of venue, and then select the corresponding keel structure, amateur training venues, suitable for single-layer keel; Professional competition venues are suitable for double-layer keels.

Double-layer keels are generally used for competitions, and single-layer keels are generally used for ordinary training.

Single-layer structure and double-layer keel structure, single and double-layer structure have their own unique properties. Take a look at the single-layer structure in indoor sports hardwood flooring today. Simple single-layer indoor sports solid wood flooring, a kind of hard floor in direct contact with the cement floor, their cost and price are relatively low, with a certain protective performance, but there is still a gap with the national sports stadium floor, they are produced relatively early, and the current society has used updated single-layer knots.
