Construction of double keel sports wooden floor for basketball court in gymnasium

Scope of application: sports wooden floors in gymnasiums, meet the technical indicators requirements of the Basketball Federation (FIBA) for professional sports wooden floors, and can undertake the Olympic Games, Intercontinental and other top-level sports such as basketball, gymnastics, volleyball, handball, badminton, table tennis, wrestling , boxing, martial arts and other professional and special sports events;
Paving process:
The suspension paving process is the most advanced sports floor paving process today. The NBA floor in the United States adopts this paving process. Three major functions (sports function, protection function, technical function) and six sports performance indicators. The traditional wire binding method and the expansion bolt and the ground fixing method do not have the above advantages, but correspondingly restrain the elasticity of the floor. When athletes train on it, they will feel that the floor is too hard and the elasticity is poor, which is more likely to cause injury to the athlete. Therefore, the wooden floor of the site adopts suspended pavement in the design of the paving process to pursue the best effect.
uMaterial description:
1) Paint: The factory-preset paint for the surface layer is imported special paint for non-slip and wear-resistant sports floors.

Factory Preset Paints On-site painting
Comparison of Strengths 1. The whole process of the paint layer is completely carried out in a dust-free environment, the performance indicators of the paint layer are balanced, and the paint layer has strong adhesion
2. The quality is stable and the texture is uniform, which can effectively guarantee the technical indicators of sliding friction of professional sports floors;
3. It can completely maintain the original color of the original wood, is durable, and greatly improves the long service life of the floor.
1. On-site paint is greatly affected by surrounding environmental factors and construction workers, and it is difficult to ensure the consistency and uniformity of the entire venue paint;
2. The dust in the air is easy to adhere to the surface of the paint layer, resulting in the sliding friction performance of the paint layer not meeting the requirements of professional sports floors;
3. Dust adhering to the paint layer can cause serious damage to the floor paint layer, fromAnd reduce the effective life of the floor.


2) Surface floor: domestic maple sports floor
Size: 22×65×(400-900)mm
The 22mm thick domestic high-quality maple sports floor is selected. The wood is of natural color, good color, anti-fatigue, anti-bending and long life. It is suitable for the local moisture content, and meets the comprehensive use capacity and service life of the venue in terms of deformation resistance, fatigue strength, bearing capacity and comprehensive functional physical and chemical indicators.
3) Moisture-proof layer: 0.3mmPE moisture-proof film
4) Fur floor: 18mm environmentally friendly multi-layer board.
5) Upper keel: LVL Specification: 40×50mm @ Center distance: 400mm.
The keel system that has been treated with anti-corrosion, moisture-proof and termite-proof treatment is selected, so that the bearing capacity and elastic performance of the floor system are lasting and consistent.


6) Elastic pad: nylon elastic pad
Specification: 18mm Center distance: 400mm
Elastic rubber pad, non-aging, elastic balance, stable and reliable.
7) Lower keel: LVL Specification: 40×50mm Center distance: 400mm.
The keel system that has been treated with anti-corrosion, moisture-proof and termite-proof treatment is selected, so that the bearing capacity and elasticity of the floor system are lasting and consistent.
8) Leveling wooden block: solid wood block
9) Floor system height: 138mm (the site elevation can be adjusted according to the actual situation on site).
10) Ventilation: The wooden floor system in the gymnasium is designed with a unique air self-circulation process. The cavity under the floor system and the ventilation holes on the skirting board form a circulation chain with the external environment, so that the floor is always maintained in a balanced air In the circulation environment, the quality is therefore stable and durable, so as to ensure the ventilation of the wooden floor, so that the ground moisture can be discharged smoothly.
