Description

Technical Field

[0001] The utility model relates to the field of sports floors, in particular to a three-layer keel elastic sports floor. Background Art

[0002] Sports floors are widely used in indoor sports venues such as gymnasiums, fitness centers, and cultural and sports activity centers. With the development of the times and the improvement of people's living standards, people have higher and higher requirements for sports venues. They not only require sports floors to have sports performance, but also require sports floors to have protective performance.

[0003] At present, existing sports floors usually have a keel frame laid on the ground, a load-bearing plate laid on the keel frame, and then a panel laid on the load-bearing plate. However, this type of sports floor is relatively hard, has poor elasticity, and absorbs less vibration and impact generated during exercise, which can easily lead to sports injuries.

[0004] Therefore, we need to design a three-layer keel elastic sports floor to solve the above problems. Utility Model Content

[0005] The existing sports floor is relatively hard, has poor elasticity, and absorbs little vibration and impact generated during exercise, which easily leads to sports injuries. The purpose of the utility model is to solve the above problems by providing a three-layer keel elastic sports floor.

The utility model can greatly improve the elasticity and buffering and shock-absorbing performance of the floor by arranging the first buffer pad, the elastic bearing layer, the second buffer pad and the elastic shock-absorbing pad, so that the floor has a good impact absorption effect, can absorb the vibration and impact generated during exercise to the maximum extent, and avoid sports injuries.

[0007] In some embodiments, the elastic bearing layer includes a first bearing plate, an elastic sponge layer, and a second bearing plate, which are arranged in sequence from top to bottom, wherein the first bearing plate is arranged on the bottom surface of the first buffer pad, and the middle keel is arranged on the bottom surface of the second bearing plate. Thus, the elastic bearing layer has good elasticity and buffering and shock absorbing effects, and can improve the impact absorption performance of the floor.

[0008] In some embodiments, both the first loading board and the second loading board are larch plywood, and the thickness of the first loading board and the second loading board are both 15 mm.

[0009] In some embodiments, the elastic sponge layer is a polyurethane foam material, and the thickness of the elastic sponge layer is 20 mm. Thus, the elastic sponge layer has a buffering and shock absorbing effect, and can effectively improve the impact absorption performance of the floor.

[0010] In some embodiments, the first buffer pad and the second buffer pad are both made of hard rubber material, and the thickness of the first buffer pad and the second buffer pad are both 5 mm. Therefore, the first buffer pad and the second buffer pad have a certain buffering effect.

[0011] In some embodiments, the elastic shock-absorbing pad is made of a soft rubber material, and the thickness of the elastic shock-absorbing pad is 13 mm. Therefore, the soft rubber material has great elasticity, and can produce a large deformation under a very small external force, and can return to its original shape after the external force is removed. The elastic shock-absorbing pad can play a very good shock-absorbing role.

[0012] In some embodiments, the top surface of the panel is provided with an anti-skid coating, and the anti-skid coating is a high-gloss UV paint. Thus, the high-gloss UV paint has the effects of friction resistance and anti-skid, and can ensure that the anti-skid coefficient of the floor is 0.5-0.7, which can effectively avoid sports injuries caused by the floor being too slippery or too rough.

[0013] In some embodiments, the panel is formed by splicing two sub-panels, and two opposite sides of the sub-panels are respectively provided with tenons and grooves. Thus, the two sub-panels are spliced ​​together by plugging the tenons and grooves to form a panel.

[0014] In certain embodiments, the panel is a solid wood multilayer board, and the thickness of the panel is 18 mm.

[0015] In certain embodiments, the upper keel, the middle keel and the lower keel are all made of dried larch wood, and the thickness of the upper keel, the middle keel and the lower keel are all 14 mm.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1. The utility model can greatly improve the elasticity and buffering and shock-absorbing performance of the floor by arranging the first buffer pad, the elastic bearing layer, the second buffer pad and the elastic shock-absorbing pad, so that the floor has a good impact absorption effect, can absorb the vibration and impact generated during exercise to the maximum extent, and avoid sports injuries.

[0018] 2. The elastic sponge layer of the utility model is a polyurethane foam material, which has a buffering and shock-absorbing effect and can effectively improve the impact absorption performance of the floor.

[0019] 3. The anti-slip coating of the utility model is a high-gloss UV paint, which has the effects of friction resistance and anti-slip, and can ensure that the anti-slip coefficient of the floor is 0.5-0.7, which can effectively avoid sports injuries caused by the floor being too slippery or too astringent.
