However, the sound absorption effect of existing sports floors is poor, and the elastic shock absorption performance of sports floors needs to be improved.

[0004] Therefore, we need to design a high-elasticity shock-absorbing and sound-absorbing sports floor to solve the above problems. Utility Model Content

The utility model adopts a double-layer keel structure formed by stacking a horizontal LVL keel and a longitudinal LVL keel, and by arranging a first-level shock-absorbing pad between the horizontal LVL keel and the longitudinal LVL keel, and arranging a second-level shock-absorbing pad on the bottom surface of the longitudinal LVL keel, the elasticity of the stacked structure and the elasticity of the material itself can be effectively utilized to improve the elastic shock-absorbing performance of the floor; by arranging solid cement bricks on the bottom surface of the second-level shock-absorbing pad, the cavity area between the panel and the ground is increased, and by filling the cavity between the panel and the ground with sound-absorbing cotton, the sound absorption effect of the floor is greatly improved.

[0007] In some embodiments, the panel is formed by splicing a plurality of slats, one side of the slats is provided with a tenon, and the other side is provided with a groove adapted to the tenon. Thus, this structure allows the floor to be replaced by replacing only the damaged slats when it is damaged, and the maintenance cost is low.

[0008] In some embodiments, the top surface of the panel is provided with an anti-skid paint layer. Thus, by providing the anti-skid paint layer, the floor can have better anti-skid performance.

[0009] In some embodiments, the anti-slip paint layer is a high-gloss UV paint. Therefore, the sliding friction coefficient of the high-gloss UV paint is 0.5-0.7, which can effectively prevent sports injuries to athletes caused by too slippery floors.

[0010] In some embodiments, the spacing between each of the transverse LVL keels is 245 mm, and the spacing between each of the longitudinal LVL keels is 365 mm.

[0011] In some embodiments, the planks are maple planks, as maple wood is relatively hard and has high impact resistance.

[0012] In some embodiments, the transverse LVL keel and the longitudinal LVL keel are both made of larch material by laminating and bonding. Therefore, the transverse LVL keel and the longitudinal LVL keel are made by hot pressing multiple layers of larch material veneer bonding with formaldehyde-free glue, which has the advantages of being waterproof, anti-corrosive, insect-proof, and elastic, thereby strengthening the elastic buffering effect of the floor and enhancing the absorption of vibration and impact during exercise.

[0013] In some embodiments, the primary shock-absorbing pad is made of polyurethane rubber, and the secondary shock-absorbing pad is made of methyl vinyl silicone rubber. Thus, both the primary shock-absorbing pad and the secondary shock-absorbing pad are made of rubber material, which has high elasticity, can play a very good shock-absorbing role, and can further improve the elasticity of the floor.

[0014] In some embodiments, the sound-absorbing cotton is polyurethane fiber cotton. Therefore, polyurethane fiber cotton belongs to a porous sound-absorbing material and has good sound-absorbing performance.
