[0007] In some embodiments, the distribution of the leveling pads on the bottom surface of the third keel corresponds to the distribution of the second elastic buffer pads on the top surface of the third keel.

[0008] In some embodiments, the elastic shock-absorbing pad is a double V-shaped structure.

[0009] In some embodiments, the elastic shock-absorbing pad is provided with ventilation holes.

[0010] In some embodiments, the first elastic buffer pad and the second elastic buffer pad are both made of black silicone.

[0011] In some embodiments, the elastic shock-absorbing pad is made of methyl vinyl silicone rubber.

[0012] In some embodiments, the panel is formed by splicing two sub-panels through a tongue-and-groove structure.

[0013] In some embodiments, the sub-panel is a solid wood board or a solid wood multi-layer board.

[0014] In some embodiments, the material of the supporting board is eucalyptus or larch.

[0022] The utility model will be further described in detail below in conjunction with the accompanying drawings.

[0023] The following describes the utility model and its implementation methods, which are not restrictive and the actual implementation methods are not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.

[0024] refer to Figure 1-2The utility model provides a three-layer keel sports floor, including a panel 1, a bearing plate 2 is arranged on the bottom surface of the panel 1, first keels 3 are arranged on both sides of the bottom surface of the bearing plate 2, a combined keel is arranged at intervals on the bottom surface of the first keel 3, the first keel 3 is perpendicular to the combined keel, a first elastic buffer pad 4 is arranged at the intersection of the first keel 3 and the combined keel, the combined keel includes a second keel 5 and a third keel 7 arranged in parallel up and down, a second elastic buffer pad 6 is arranged between the second keel 5 and the third keel 7, a leveling pad 8 is arranged at intervals on the bottom surface of the third keel 7, and an elastic shock-absorbing pad 9 is arranged at the bottom of the leveling pad 8. Specifically, the distribution of the leveling pad 8 on the bottom surface of the third keel 7 corresponds to the distribution of the second elastic buffer pad 6 on the top surface of the third keel 7. The utility model can improve the impact absorption of the floor by arranging the first elastic buffer pad 4, the second elastic buffer pad 6 and the elastic shock-absorbing pad 9, so that the floor has good impact absorption performance (impact absorption rate ≥ 53%), can effectively prevent athletes from being injured by strong impacts during exercise, and can better meet the protection requirements of sports venues.

[0025] The elastic shock-absorbing pad 9 is a double V-shaped structure. When the elastic shock-absorbing pad 9 is deformed, it can quickly return to its original shape, which is beneficial to improving the impact absorption of the floor. The elastic shock-absorbing pad 9 is provided with a vent hole 91. By providing the vent hole 91 on the elastic shock-absorbing pad 9, the force on the elastic shock-absorbing pad 9 can be more uniform, which is beneficial to buffering and can effectively improve the impact absorption of the floor.

[0026] The first elastic buffer pad 4 and the second elastic buffer pad 6 are made of black silica gel, which can buffer and absorb shock. The elastic shock-absorbing pad 9 has a specification of 10×40×60 mm and is made of methyl vinyl silicone rubber. Methyl vinyl silicone rubber has high elasticity and can produce large deformation under a small external force. It can return to its original state after the external force is removed, which is conducive to improving the impact absorption of the floor.

[0027] The top surface of the panel 1 is provided with an anti-skid coating, which is a high-gloss UV paint. By providing the high-gloss UV paint on the top surface of the panel 1, the high-gloss UV paint can ensure that the anti-skid coefficient of the floor is 0.4-0.7, so that the floor has good anti-skid performance. The panel 1 is formed by two sub-panels 11 spliced ​​by a tongue-and-groove structure, and the sub-panels 11 are solid wood boards or solid wood multilayer boards. The material of the bearing plate 2 is eucalyptus or larch wood, and the first keel 3, the second keel 5 and the third keel 7 are all made of dried larch wood. The specifications of the first keel 3 are 20×78×1840mm, and the specifications of the second keel 5 and the third keel 7 are both 14×78×1840mm. The leveling pad 8 is a solid wood multilayer board used for structural leveling, and the specifications of the leveling pad 8 are 12×78×60mm.

[0028] The panel 1 is fixedly connected to the bearing plate 2 by screws, the bearing plate 2 is fixedly connected to the first keel 3 by nails or screws, the first keel 3 is bonded to the first elastic buffer pad 4 by adhesive and reinforced by nails, the first elastic buffer pad 4 is fixedly connected to the second keel 5 by screws, the second keel 5 is bonded to the second elastic buffer pad 6 by adhesive and reinforced by nails, the second elastic buffer pad 6 is fixedly connected to the third keel 7 by screws, the third keel 7 is fixedly connected to the leveling pad 8, and the leveling pad 8 is fixedly connected to the elastic shock-absorbing pad 9 by nails. Thus, by using screws or nails to fix the connection between each layer, the structure becomes an integral whole, thereby improving the structural stability of the floor.

[0029] When in use, the three-layer keel sports floor can be used in sports venues such as basketball halls, badminton halls, and gyms. The three-layer keel sports floor has good impact absorption performance and can better meet the protection requirements of sports venues.
