Description

Technical Field

[0001] The utility model belongs to the technical field of floor paving materials, and relates to a wooden floor, in particular to a highly wear-resistant and shock-absorbing sports wooden floor. Background Art

[0002] With the holding of various high-level sports events, more and more people are participating in sports. Professional sports wooden floors are often laid in sports venues, which have excellent impact resistance, shock absorption, and deformation resistance. When people exercise, they will have a strong impact on the ground. After the impact rebounds, it will cause damage to the athlete's ankle joints, meniscus, spine, brain, etc. The role of sports wooden floors is to effectively prevent athletes from being injured during exercise.

[0003] At present, most sports wooden floors have a paint finish on the surface, which has limited wear resistance. As the frequency of sports games increases, the surface of the sports wooden floor will be worn to varying degrees, and the anti-slip effect will decrease, greatly increasing the risk of damage during exercise. At the same time, the shock-absorbing layer commonly used in existing sports wooden floors is synthetic rubber, which will gradually age with the increase of years of use, and the impact resistance and shock absorption effect will decrease, which will also increase the risk of injury during exercise.

[0004] To this end, the utility model discloses a highly wear-resistant and shock-absorbing sports wooden floor. Summary of the invention

[0005] In view of the deficiencies in the above-mentioned prior art, the purpose of the utility model is to disclose a highly wear-resistant and shock-absorbing sports wooden floor to solve the problems raised in the above-mentioned background technology.

[0006] The utility model adopts the following technical solutions:

[0007] A highly wear-resistant and shock-absorbing sports wooden floor comprises a surface floor, a bearing layer and a keel layer, wherein the surface floor is a highly wear-resistant composite floor, the surface layer of which is a decorative layer, the bottom layer of which is a multi-layer plywood layer, and a glue curing layer is provided between the decorative layer and the multi-layer plywood layer; the bearing layer is an oriented strand board, and a moisture-proof layer is provided between the surface floor and the bearing layer; the keel layer is composed of a plurality of parallel arranged keel strips, the keel strips are carbonized veneer laminates, and the bearing layer is fixedly provided on the surface of the keel layer; and a shock-absorbing layer is provided at the bottom of the keel layer.

[0008] In a preferred disclosed example of the utility model, the decorative layer is impregnated paper with a wood grain pattern impregnated with melamine, the surface of which is sprayed with aluminum oxide, and the wear resistance coefficient is 9000r or above.

[0009] In a preferred disclosed example of the utility model, the surface floor is provided with tongues and grooves in the length and width directions respectively.

[0010] In a preferred disclosed example of the utility model, the bearing layer is an oriented strand board with a thickness of 10 to 12 mm.

[0011] In a preferred disclosed example of the utility model, the moisture-proof layer is a non-woven fabric with a gram weight of not less than 80g / ㎡, which can effectively prevent ground moisture from eroding the surface floor and prevent the floor from deforming.

[0012] In a preferred embodiment of the utility model, the keel layer is formed by laying a plurality of keel strips in the same direction, and the spacing between two adjacent keel strips is 420-450mm. The carbonized veneer laminate is treated with high temperature carbonization, and the anti-corrosion and anti-insect performance is improved, reducing the process of applying the preservative in the later stage.

[0013] In a preferred disclosed example of the utility model, the shock-absorbing layer is a foamed polypropylene pad with a thickness of 15 to 20 mm and a foaming ratio of 20 to 25 times.

[0014] Furthermore, the length of the foamed polypropylene pad is consistent with the size of the keel strip to which it is bonded, and the spacing between two adjacent pads is 320-350 mm.

[0015] Furthermore, the foamed polypropylene pad is laid along the length direction of the keel strip.

[0016] Expanded Polypropylene (EPP) is a lightweight, heat-insulating, flame-retardant plastic material made from polypropylene through a foaming process. Polypropylene is a common thermoplastic that can be processed over a wide temperature range due to its high strength, stiffness, and heat resistance.

[0017] Beneficial Effects

[0018] The sports wooden floor provided by the utility model adopts a three-layer paving structure. The surface floor is a highly wear-resistant floor, which is formed by pressing a surface-impregnated wood-grained facing paper and a multi-layer plywood. In addition to meeting various performance standards, the surface of the facing paper is impregnated with aluminum oxide with excellent wear resistance, making the floor more wear-resistant and longer-lasting. Oriented strand board is used as the bearing layer, which improves the bearing strength and anti-deformation ability of the sports wooden floor and protects athletes from injury. At the same time, the use of oriented strand board layer instead of solid wood bearing layer not only saves wood resources but also significantly reduces costs. The keel is a carbonized veneer laminate. After high-temperature carbonization treatment, the original wood fiber in the wood is destroyed, free water is lost, and microorganisms cannot breed in the wood, which not only increases the bearing strength and anti-deformation ability of the sports wooden floor, but also improves the anti-corrosion ability and increases the service life. The foamed polypropylene used has excellent shock absorption performance, elasticity, high quality and light weight, temperature resistance and waterproofness, and can be recycled. It can improve the overall shock absorption performance of the sports wooden floor, and the environmental protection performance is more prominent. BRIEF DESCRIPTION OF THE DRAWINGS
