Description

Technical Field

[0001] This utility model relates to the field of wood flooring, specifically a wear-resistant composite wood flooring. Background Technology

[0002] Composite wood flooring is a widely used flooring material in the building decoration field. With its diverse decorative effects and relatively simple installation, it is widely used in homes and commercial spaces. However, over long-term use, problems such as deformation and loosening due to unreasonable structural load-bearing and localized stress concentration are common. For example, in areas with frequent foot traffic, the planks are prone to denting, and the gaps between the planks widen, affecting the user experience and aesthetics, shortening the floor's lifespan, and making it difficult to meet the needs of long-term, high-frequency use scenarios.

[0003] Publication number CN219033892U describes a wear-resistant composite wood flooring that employs a multi-layer structure design. The main body of the composite wood flooring consists of a base layer, a decorative layer, a modified wood layer, and a bamboo-plastic composite wood flooring layer. The bamboo-plastic composite wood flooring layer enhances the wear resistance, and the overall support strength is enhanced by setting equidistantly distributed reinforcing components. This design attempts to optimize the performance of the composite wood flooring from a structural perspective, thereby alleviating to some extent the wear resistance and load-bearing problems caused by the inadequacy of a single structure.

[0004] However, it still has shortcomings in load distribution and structural stability. The interlayer connections and force transmission lack a precise layered distribution mechanism, making it prone to localized pressure buildup during interlayer transmission. Furthermore, the panel splicing relies on conventional connections, which can easily lead to deformation and loosening at the joints under long-term, high-frequency foot traffic and impacts. If the reinforcement components are not adequately adapted to the connections between layers, it cannot function like a layered load-bearing system.

[0005] Therefore, a wear-resistant composite wood flooring is proposed to solve the problems mentioned above. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a wear-resistant composite wood flooring that can solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant composite wood flooring, comprising an upper layer board, a middle layer board provided on both sides of the bottom of the upper layer board, a bottom pressure plate provided at the bottom of the middle layer board, a sandwich convex plate provided in the middle of the middle layer board, and second insertion holes provided on both sides of the sandwich convex plate. A side panel is provided on one side of the middle layer plate, and a first insertion hole is provided on the surface of the side panel. Insert rods are inserted into the inner side of the first insertion hole and the second insertion hole. An anti-slip part is provided on the surface of the upper layer plate, and a buried frame is provided on the outer side of the top of the upper layer plate. An insert is provided in the middle of both sides of the buried frame.

[0008] Preferably, the side panel and the insert are connected by insertion, and the buried frame and the upper plate are connected by fixing.

[0009] Preferably, the anti-slip part and the upper plate are an integrated structure.

[0010] Preferably, the side panel is glued to the middle layer plate and the sandwich convex plate.

[0011] Preferably, the external structure of the sandwich convex plate is a convex-shaped structure, and the diameter of the second insertion hole on the surface of the sandwich convex plate is equal to the diameter of the first insertion hole.

[0012] Preferably, the bottom of the bottom pressure plate is provided with multiple protrusions.

[0013] Preferably, the area of ​​the bottom pressure plate is equal to the area of ​​the upper plate.

[0014] Compared with the prior art, the present invention provides a wear-resistant composite wood flooring with the following advantages: 1. The top layer, middle layer, interlayer convex plate, and bottom pressure plate form a multi-layered collaborative load-bearing system. When pressure is applied to the top layer, the middle layer bears the force on both sides, the interlayer convex plate bears the force in the middle, and then the bottom pressure plate further disperses the pressure to the base layer. This achieves layered transmission and dispersion of pressure, avoids local stress concentration, and structurally ensures that the wood flooring is not easily deformed under foot traffic and impact, maintaining overall stability.

[0015] 2. Insert the insert rod into the first insertion hole of the side panel and the second insertion hole of the interlayer protrusion plate, and insert the inlay into the groove of the side panel to strengthen the splicing of multiple wood flooring pieces, so that the boards form a stable whole and resist the risk of loosening caused by stepping and impact. The buried frame covers the top outer side of the upper board, seals the gaps between the boards, reduces the intrusion of external impurities such as dust and moisture, delays the aging of the internal structure, and extends the service life of the wood flooring, which can meet the needs of long-term high-frequency use scenarios such as shopping malls and showrooms.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] A wear-resistant composite wood flooring includes an upper board 6, a middle board 3 on both sides of the bottom of the upper board 6, a bottom pressure plate 4 at the bottom of the middle board 3, a sandwich convex plate 9 in the middle of the middle board 3, and second insertion holes 10 on both sides of the sandwich convex plate 9. A side panel 5 is provided on one side of the middle layer plate 3. A first insertion hole 7 is provided on the surface of the side panel 5. An insertion rod 8 is inserted into the inner side of the first insertion hole 7 and the second insertion hole 10. An anti-slip part 1 is provided on the surface of the upper layer plate 6. A buried frame 2 is provided on the outer side of the top of the upper layer plate 6. An insert block 11 is provided in the middle of both sides of the buried frame 2.

[0020] Example 1: Please refer to Figure 1 - Figure 5 The insertion rod 8 is replaced with a metal pin with elastic teeth. The surface of the metal pin is treated with rust prevention. When the pin is inserted into the first insertion hole 7 and the second insertion hole 10, the elastic teeth open in the insertion hole and lock the hole wall to prevent the pin from loosening and falling out. At the same time, the material of the inlay block 11 of the buried frame 2 is replaced with hard rubber. The surface of the rubber inlay block 11 is provided with anti-slip texture. When inserted into the groove of the side panel 5, the rubber elasticity is used to fill tightly, which enhances the lateral constraint between the panels and can buffer the slight vibration caused by stepping. The glued connection between the middle layer board 3 and the sandwich convex plate 9 is replaced by a tenon and mortise joint with a small amount of structural adhesive for fixation. Corresponding tenons and mortises are machined on the contact surfaces of the middle layer board 3 and the sandwich convex plate 9. The tenon and mortise joint first achieves preliminary positioning and mechanical engagement, and the structural adhesive fills the tiny gaps and strengthens the connection. In this way, the connection strength between the middle layer board 3 and the sandwich convex plate 9 is significantly improved. When bearing the pressure of the upper layer board 6, the force transmission is more direct and stable, reducing the risk of structural deformation due to glue failure. This embodiment improves the connecting components, from the locking of the pins and the buffer of the insert 11 to the connection of the middle layer, and strengthens the splicing and interlayer connection of the wood flooring in multiple dimensions, thereby improving the overall structure's resistance to loosening and deformation. It is suitable for commercial places with high traffic and high requirements for floor stability, such as shopping mall corridors and showrooms.

[0021] Example 2: Please refer to Figure 1 - Figure 5 The anti-slip part 1 of the upper plate 6 is optimized into a composite wear-resistant structure. On the basis of the original anti-slip texture, a thin ceramic wear-resistant layer is hot-pressed onto the surface. The ceramic layer is combined with the upper plate 6 through a special process, which not only retains the anti-slip function, but also greatly improves the wear resistance and resists scratches from sharp objects and high-frequency stepping. The protruding part at the bottom of the bottom pressure plate 4 is replaced with an elastic rubber protrusion. A micro spring is embedded in the rubber protrusion. When the upper plate 6 is under pressure, the pressure is transmitted to the bottom pressure plate 4 through the middle plate 3 and the interlayer protrusion 9. The elastic rubber protrusion and the micro spring work together to absorb and buffer the impact force, reduce the vibration transmitted to the base layer, and improve the comfort underfoot. At the same time, the material of the middle plate 3 is replaced with bamboo fiber reinforced board. The high strength and high toughness of bamboo fiber enhance the load-bearing performance of the middle layer, reducing the overall weight of the floor while ensuring structural strength. The connection between the side panel 5 and the middle layer board 3 and the sandwich convex plate 9 is reinforced with metal reinforcing strips. Thin metal reinforcing strips are embedded at intervals on the adhesive surfaces of the side panel 5, the middle layer board 3, and the sandwich convex plate 9. The two ends of the reinforcing strips extend into the middle layer board 3 and the side panel 5, respectively. Through the combined action of mechanical interlocking and adhesive bonding, the tear resistance of the side connection is improved. This embodiment, from surface wear resistance and bottom shock absorption to middle layer load-bearing reinforcement, is suitable for scenarios with special needs for wear resistance and shock absorption, improving the user experience and functional versatility of wood flooring.

[0022] When in use, the upper board 6 is the surface layer that comes into direct contact with the user. Its anti-slip part 1 increases the coefficient of friction to provide stable grip for walking and avoid the risk of slipping. The buried frame 2 surrounds the top of the upper board 6. During installation, its two side inserts 11 can be inserted into the corresponding grooves of the adjacent wood flooring side panel 5 to fill the gaps between the boards, enhance the overall sealing and aesthetics of the installation, and limit the lateral displacement between the boards. The middle layer board 3 is located on both sides of the bottom of the upper layer board 6, and together with the middle sandwich convex plate 9, it forms a load-bearing structure. The sandwich convex plate 9 is convex in shape, which increases the contact area with the upper and lower layers and improves the structural stability. When the upper layer board 6 is under pressure, the pressure is transmitted to the sides and down through the upper layer board 6. The middle layer board 3 bears the pressure on both sides, and the sandwich convex plate 9 bears the pressure in the middle, dispersing the load. The side panel 5 is attached to the sides of the middle layer board 3 and the sandwich convex plate 9, and the side structure is strengthened by gluing. The first insertion hole 7 on its surface is matched with the second insertion hole 10 of the sandwich convex plate 9. After inserting the insertion rod 8, the splicing and locking of multiple wood flooring pieces is realized, making the connection between the boards more stable, transmitting longitudinal and lateral forces, and avoiding loosening and misalignment after installation. The bottom pressure plate 4 covers the bottom of the middle layer plate 3 and the sandwich convex plate 9. Its area is adapted to the upper layer plate 6. The protruding part at the bottom increases the friction and support points in contact with the base layer, further dispersing the pressure transmitted from the upper layer to the base layer, reducing the force per unit area of ​​the upper layer plate 6, improving the overall load-bearing capacity and deformation resistance of the wood flooring, and extending its service life. The structure of each layer is connected by mechanical means or glued to form a complete force system from surface anti-slip and gap sealing to the load-bearing distribution of the middle layer and the stable support at the bottom, ensuring that the wood flooring is wear-resistant, stable and not easily deformed during use.

[0023] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
