[0006] A structure is provided between the solid wood layer and the cushion layer to restrict the movement of the two in the horizontal and vertical directions.

[0007] The hardness of the buffer layer is lower than that of the solid wood board layer, and there is no contact between the two solid wood board layers.

[0010] In a preferred embodiment, a first carbon fiber cloth is further included, and the first carbon fiber cloth is arranged between the upper solid wood floor and the cork powder rubber pad. The first carbon fiber cloth is embedded and bonded between the upper solid wood floor and the outer wall surface of the cork powder rubber pad through a gluing and hot pressing process. The first carbon fiber cloth increases the strength of the connection surface, while avoiding the probability of relative misalignment between the upper solid wood floor and the cork powder rubber pad, thereby improving the service life.

[0011] In a preferred embodiment, a second carbon fiber cloth is further included. The second carbon fiber cloth is arranged between the cork powder rubber mat and the lower solid wood floor. The second carbon fiber cloth is embedded and bonded between the lower solid wood floor and the outer wall surface of the cork powder rubber mat through an adhesive hot pressing process. The second carbon fiber cloth increases the strength of the connecting surface and avoids the probability of relative misalignment between the lower solid wood floor and the cork powder rubber mat, thereby improving the service life.

[0012] In a preferred embodiment, the cork powder rubber pad is made by mixing cork powder and rubber and then shaping and cooling them, which can reduce production costs and improve the utilization rate of cork.

[0013] In a preferred embodiment, the mass ratio of the cork powder to the rubber is: -:-.

[0014] In a preferred embodiment, the thickness of the upper solid wood floor and the lower solid wood floor are the same, and the thickness of the cork powder rubber pad is not less than half of the thickness of the upper solid wood floor.

[0015] The advantages and positive effects of the present invention are:

[0016] 1. The cushioning and sound insulation layer made of cork and rubber effectively reduces the noise caused by stepping on harder shoes, effectively reduces noise, reduces the hidden dangers of disputes between neighbors upstairs and downstairs, and its anti-buffering effect is significantly improved, which can improve the physical sensation of walking.

[0017] 2. The composite design of the first carbon fiber cloth and the second carbon fiber cloth can ensure that the fitting positions are well snapped into place, avoiding the abnormal creaking noise in the later stage. BRIEF DESCRIPTION OF THE DRAWINGS
