Description

A wood plastic floor suitable for sports Technical Field

[0001] The present invention relates to the technical field of flooring, and more particularly to a wood-plastic flooring suitable for sports use. Background Art

[0002] Currently, sports flooring in the domestic and international sports flooring industry is typically constructed from solid wood and other wood materials. The advantages of sports wood flooring include: 1. Aesthetics; 2. Comfort; 3. Safety. However, sports wood flooring also has some disadvantages: 1. It cannot be exposed to moisture. Sports wood flooring is made of pure wood, so care must be taken to keep the floor dry. If the flooring gets damp, it can easily become damaged, bulging, and deformed. 2. It cannot be exposed to direct sunlight. Regardless of the type of wood flooring, it should not be exposed to direct sunlight, as this can easily cause the flooring to swell and crack. 3. Termite damage: If the moisture content of a sports wood floor is too high or it is exposed to a humid environment, termites will easily infest the flooring, eating away the wood and further accelerating its decay and damage. 4. Daily maintenance costs are high. In summer, the air humidity is high, and the gymnasium needs to be ventilated regularly to ensure the indoor air humidity balance; in winter, the gymnasium should use exhaust fans for regular ventilation. In rainy and snowy weather, doors and windows should be closed to prevent rain from seeping into the room through window gaps and damaging the wooden floor; in summer or when the sun is strong, curtains should be drawn to prevent the sports wooden floor from being exposed to the sun. Cleaning staff should clean the sports wooden floor at least twice a day and deal with water stains on the sports wooden floor in a timely manner.

[0003] Therefore, it is an urgent problem for those skilled in the art to develop a wood-plastic floor suitable for sports use that is stable in structure, easy to install, and has corrosion-resistant and moisture-proof properties.

[0004] Summary of the Invention

[0005] In view of this, the present invention provides a wood-plastic floor suitable for sports use, which has a stable structure, is easy to install, and has corrosion-resistant and moisture-proof properties.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A wood plastic floor suitable for sports use, comprising:

[0008] Panels, multiple panels are arranged side by side, and adjacent panels are spliced ​​with each other;

[0009] A keel, the keel comprising: a main keel and a secondary keel; a plurality of the main keels are arranged side by side and spaced apart, a plurality of the secondary keels are arranged side by side and spaced apart on top of the main keel, the secondary keels are arranged perpendicular to the main keels, and a plurality of the panels are arranged on top of the secondary keels;

[0010] A shock-absorbing pad is arranged at the bottom of the main keel.

[0011] The beneficial effect of adopting the above technical solution is that the setting of the secondary keel and the main keel in the present invention can make the structure of the bottom of the panel more stable, the shock-absorbing pad can play a shock-absorbing role, and both are made of wood-plastic material, which has moisture-proof and rot-resistant properties.

[0012] Preferably, a plug-in plate is provided on one side of the panel, and a plug-in slot is provided on the other side. The plug-in plates of adjacent panels are plugged into the plug-in slots, and can be tightly and seamlessly spliced.

[0013] Preferably, a recessed portion is provided at the bottom of one side of the panel provided with the plug-in board, an extension portion is provided at the bottom of one side of the panel provided with the plug-in slot, and the recessed portion and the extension portion of the adjacent panel cooperate with each other.

[0014] Preferably, the top end of the extension portion is provided with a first fixing groove along the length direction of the panel, and a blind rivet is provided in the first fixing groove, and the other end of the blind rivet is connected to the secondary keel. The panels are plugged into each other, and the panels and the secondary keel are fixed, so that the connection structure between the panels is more stable. The connection is made through the blind rivet, so that the connection structure is strong and there is no loosening phenomenon caused by poor nail holding force, which leads to structural instability and abnormal noise. The first fixing groove not only facilitates the connection between the panel and the secondary keel, but also avoids the influence of the blind rivet on the panel when the panel is plugged into the mortise and tenon joint.

[0015] Preferably, a foaming base layer is provided inside the panel, and a covering layer is provided outside the foaming base layer. The foaming base layer can increase the softness of the panel and enhance the shock absorption and sound absorption effects.

[0016] Preferably, the top and bottom inner walls of the panel are molded with a first reinforcing material layer, located between the foam base layer and the cladding layer. The addition of the first toughening material reduces the panel's linear thermal expansion coefficient, increases its elastic modulus, significantly improves its flexibility, and enhances its creep resistance.

[0017] Preferably, the main and secondary keels are hollow, with trusses positioned within their cavities. A second reinforcing material layer is molded into the top and bottom inner walls of the main and secondary keels. The trusses enhance the structural strength and stability of the main and secondary keels. A second toughness material is symmetrically added to the upper and lower walls of the main and secondary keels, resulting in a lower linear thermal expansion coefficient, a higher elastic modulus, significantly increased flexibility, and improved creep resistance.

[0018] Preferably, the cross-section of the main keel and the auxiliary keel is rectangular, square or trapezoidal; the cross-section shape of the main keel and the auxiliary keel after trusses are arranged inside the main keel and the auxiliary keel is "mouth" shaped, "sun" shaped or "prisoner" shaped.

[0019] Preferably, a leveling pad is provided at the bottom of the shock-absorbing pad, and the leveling pad is in the shape of a groove with an opening on one side; a first limiting notch is provided in the middle of the leveling pad, and a first limiting baffle extending upward is provided on the groove wall of the first limiting notch; limiting holes are provided at positions corresponding to the shock-absorbing pad and the first limiting baffle. When the ground foundation does not meet the horizontal standards required for a sports venue, the leveling pad can be used to adjust the distance between the panel and the ground foundation; the leveling pad can be inserted into the bottom of the shock-absorbing pad from the open side, and the first limiting baffle is elastic and is compressed during movement. After being inserted into place, the first limiting baffle pops up and is placed in the limiting hole, connecting to the shock-absorbing pad.

[0020] Preferably, a second limiting notch is formed at the bottom of the leveling gasket, and a second inclined limiting baffle extending upward is provided on the groove wall of the second limiting notch. When multiple leveling gaskets are stacked for use, adjacent leveling gaskets are connected by the second limiting notch and the second limiting baffle for limiting.

[0021] Preferably, the top of the secondary keel is provided with a second fixing groove along its length, in which a blind rivet is installed, and the other end of the blind rivet is connected to the main keel. The second fixing groove not only facilitates the connection between the secondary keel and the main keel, but also prevents the blind rivet from affecting the panel when the secondary keel and the panel are placed.

[0022] It can be seen from the above technical solutions that, compared with the prior art, the present invention provides a wood plastic floor suitable for sports use, which has the following beneficial effects:

[0023] (1) The keel and panel of the present invention are made of composite materials, which are waterproof and moisture-proof, fundamentally solving the problem that wooden products are prone to rotting, swelling and deformation after absorbing water in a humid and watery environment. They are also insect-proof and termite-proof, effectively preventing insect harassment, extending the service life, and are effectively flame-retardant.

[0024] (2) Add tough materials to the inner wall of the panel and keel to reduce the linear thermal expansion coefficient, enhance the elastic modulus, greatly increase the flexibility, and improve the creep resistance;

[0025] (3) The height of the keel can be adjusted as needed by using leveling shims. BRIEF DESCRIPTION OF THE DRAWINGS
