Jinhua Indoor Basketball Wooden Floor Table Tennis Sports Floor Indoor Basketball Hall Wooden Floor The functional index of the basketball court wooden floor, the so-called basketball court wooden floor refers to the floor specially used in sports venues such as gymnasiums and gymnasiums. According to relevant experts, it is not only necessary to lay the wooden floor of the basketball court in the stadiums such as basketball games, but also pay attention to the application of the wooden floor of the basketball court in the public fitness places. The basketball court wooden floor is different from the domestic floor, and its strength, sliding friction coefficient, impact absorption and other indicators and paving methods have special requirements. According to the German Industrial Standard (DIN18032), the wooden floor of a basketball court must have three functional characteristics, namely sports function, protection function, basic technical function and six functional indicators, namely sliding friction coefficient, ball rebound
rate, rolling load, shock absorption rate, normal vertical deflection and relative vertical deflection. To evaluate whether the wooden floor of a basketball court is qualified or not, as well as the overall structure and surface performance, the key is to look at the above six functional indicators.
1.1 Sliding friction coefficient
This indicator reflects the movement stability of the athlete on the floor. The sliding friction coefficient of the sports floor should be moderate, and its value ranges from 0.4 to 0.6. If the coefficient of sliding friction is too large, the athlete will easily fall down when the athlete suddenly stops moving during the exercise, resulting in injury, and it is easy to increase the athlete's muscle mass
If the meat load is too small, the athlete will be easily fatigued; otherwise, the athlete will be exercising.
It is difficult to stop the movement in the middle of the game, it is easy to slide out of the court, and the movement and protection function of the wooden floor of the basketball court is lost.
1.2 The rebound rate of the ball
Using a standard basketball to fall freely from a distance of 1.8m from the ground, measure the rebound height of the basketball on the wooden floor and solid ground of the basketball court respectively, and compare the two, which is the rebound rate of the ball. According to DIN18032, the basketball court wooden floor requires that the rebound rate of the ball must be greater than or equal to 90%.
1.3 Rolling load
The rolling load reflects the basic technical function of the three characteristics of the wooden floor of a basketball court. When personnel, sports equipment and devices are moved and transported on the wooden floor of the basketball court, the floor should maintain its proper strength and rigidity for a long time, such as movement, protection and use functions.
1.4 Shock Absorption Rate
This indicator requires that the wooden floor of the basketball court has a good shock absorption function, that is, when the athlete jumps up and falls back to the floor surface, at least 53% of the impulse must be absorbed by the floor, so as to prevent the athlete from injury and reduce fatigue.
1.5 Standard vertical deformation
When the floor is impacted with a force of 1500N, theThe amplitude of the sports floor on the bearing point should be less than 2.3mm. This indicator indicates that the wooden floor of a basketball court should have a certain "toughness".
1.6 Relative vertical deformation rate
When the floor is impacted by a force of 1500N, the amplitude of the floor within 500mm from the standard vertical deformation point should not be greater than 15% of the amplitude of the bearing point. This indicator shows that the wooden floor of the basketball court should have a certain "rigidity" while having a certain "toughness".
