Description

Technical Field

[0001] This utility model relates to the field of composite board technology, specifically a composite integrated environmentally friendly multilayer board. Background Technology

[0002] In modern architectural decoration, furniture manufacturing and other fields, plywood is widely used due to its good mechanical properties and processing performance. However, traditional plywood still has many problems in production and use. The structure of each layer of traditional plywood relies solely on adhesives for bonding and fixing. This single connection method has poor stability. When subjected to temperature changes, humidity fluctuations or external impacts, the layers are very prone to loosening, which can lead to delamination, warping and other phenomena, seriously affecting the structural integrity and service life of the plywood.

[0003] Meanwhile, traditional plywood lacks effective protective structures at its edges and corners, making it highly susceptible to damage from collisions during transportation, installation, and daily use, which affects the product's lifespan and aesthetics. In addition, the surface layer of some plywood is made of synthetic materials, whose texture and feel differ significantly from natural wood, making it difficult to meet consumers' demand for natural and high-quality decorative effects.

[0004] Therefore, developing a composite multilayer board with excellent environmental performance, strong structural stability, adequate edge and corner protection, and good surface finish has become an urgent problem to be solved in the industry. Utility Model Content

[0005] The purpose of this utility model is to provide a composite integrated environmentally friendly multilayer board to solve the problems mentioned in the background art, such as poor structural stability, easy delamination and warping, lack of effective protection of the edges and corners, and difficulty in meeting consumers' demand for natural and high-quality decorative effects due to the use of artificial synthetic materials for the decorative layer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite integrated environmentally friendly multilayer board, including a base layer, a connecting base layer and a top base layer are arranged sequentially above the base layer, and a decorative layer is provided on the upper surface of the top base layer. The connecting base layer is connected to the base layer and the top base layer by an adhesive layer, and the top base layer is connected to the decorative layer by an adhesive layer. The decorative layer is a thin board formed by pressing natural wood veneer.

[0007] A positioning groove is provided on the upper surface of the base layer, and positioning grooves are provided on both the upper and lower surfaces of the connecting base layer, and a positioning groove is provided on the lower surface of the top base layer.

[0008] Positioning blocks are installed in the positioning grooves connecting the upper and lower surfaces of the base layer, and the base layer is installed by the positioning blocks engaging with the positioning grooves on the surfaces of the bottom and top base layers.

[0009] Positioning holes are provided on the outer surfaces of the four corners of the base layer, connecting base layer and top base layer, and the positioning holes penetrate the upper and lower surfaces of the four corners of the base layer, connecting base layer and top base layer.

[0010] Protective corner plates are installed at the four corners of the base layer, connecting base layer and top base layer, and connecting plates are fixedly installed on the inner surface of the protective corner plates, and positioning pins are installed on the outer surface of the connecting plates.

[0011] Preferably, the protective corner plate is L-shaped, and the outer surface of the protective corner plate is flush with the outer surfaces of the base layer, the connecting base layer and the top base layer.

[0012] Using the above technical solution, the L-shaped protective corner plate can perfectly fit the four corners of the multilayer board, wrapping the edges and corners in all directions to provide effective anti-collision protection, preventing damage to the edges and corners of the multilayer board due to collisions during transportation, installation and use. At the same time, the outer surface of the protective corner plate is flush with the outer surface of each base layer, without protruding or denting outward, ensuring the flatness and aesthetics of the overall appearance of the multilayer board, and not affecting the splicing installation and visual effect of the multilayer board in actual applications.

[0013] Preferably, the positioning pin is engaged with the positioning hole, and the lower end face of the positioning pin is flush with the lower surface of the bottom base layer, and the upper end face of the positioning pin is flush with the upper surface of the top base layer.

[0014] By adopting the above technical solution, the engagement of the positioning pin and the positioning hole can form a longitudinal through-positioning of the bottom base layer, the connecting base layer and the top base layer, further restricting the relative displacement of each layer in the vertical direction, enhancing the stability of the connection between each base layer, and the upper and lower end faces of the positioning pin are flush with the lower surface of the bottom base layer and the upper surface of the top base layer respectively, so they will not protrude outwards and affect the flatness of the multilayer board surface, and also avoid bumps or obstructions caused by the protrusion of the positioning pin during use, thus ensuring the coordination and practicality of the overall structure of the multilayer board.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This composite integrated environmentally friendly multilayer board:

[0016] 1. By setting positioning grooves on the surfaces of the base layer, connecting base layer and top base layer, and using positioning blocks on the upper and lower surfaces of the connecting base layer for snap-fit ​​installation, mechanical positioning connection is added to the adhesive bonding of each layer structure. This effectively solves the problem of delamination and warping that easily occurs when traditional multilayer boards are connected by adhesive alone, greatly enhances the overall structural stability and impact resistance of multilayer boards, and extends their service life.

[0017] 2. The veneer layer is made of thin boards formed by pressing natural wood veneer. Compared with synthetic materials, it can not only present natural and realistic wood texture and feel, meeting consumers' demand for high-quality decorative effects, but also natural materials are more environmentally friendly, reducing the release of harmful substances that may be caused by synthetic materials.

[0018] 3. Protective corner plates are installed at the four corners of the base layer, connecting base layer, and top base layer. The protective corner plates are L-shaped and their outer surfaces are flush with the outer surfaces of each base layer. This effectively protects the edges and corners of the plywood from collision damage during transportation, installation, and use, without affecting the overall aesthetics of the plywood. At the same time, the protective corner plates are installed by engaging with the positioning holes of each base layer through connecting plates and positioning pins, further enhancing the stability of the protective structure.

[0019] 4. The layers are connected by a combination of adhesive bonding and positioning grooves and positioning blocks. Positioning pins pass through positioning holes to further position and fix each layer. The combination of multiple connection methods makes the overall connection of the multilayer board tighter and stronger, effectively resisting the adverse effects of temperature changes and humidity fluctuations.

[0027] 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.

[0028] Please see Figures 1-6 This utility model provides a technical solution: a composite integrated environmentally friendly multilayer board.

[0029] Example 1: This example discloses: a base layer 1, a connecting base layer 2 and a top base layer 3 are arranged sequentially above the base layer 1, and a decorative layer 4 is arranged on the upper surface of the top base layer 3. The connecting base layer 2 is connected to the base layer 1 and the top base layer 3 by an adhesive layer 5. The top base layer 3 is connected to the decorative layer 4 by an adhesive layer 5. The decorative layer 4 is a thin board formed by pressing natural wood veneer.

[0030] The multi-layer board is composed of a base layer 1, a connecting base layer 2, and a top base layer 3 stacked in sequence. A decorative layer 4 is set on top of the top base layer 3. Each layer is bonded together by an adhesive layer 5 to form a basic layered structure, ensuring the initial stability of the overall structure.

[0031] The fourth veneer layer uses a thin board pressed from natural wood veneer to replace traditional synthetic veneers. It utilizes the environmentally friendly properties of natural wood veneer to reduce the release of harmful substances, while enhancing the decorative effect through the natural wood grain, thus solving the problems of traditional veneers being environmentally unfriendly and having low texture realism.

[0032] The multi-layer substrate design, combined with the bonding effect of adhesive layer 5, improves the overall mechanical properties of the multi-layer board, laying the foundation for subsequent enhancement of structural stability.

[0033] Example 2: This example is based on Example 1: The upper surface of the base layer 1 is provided with a positioning groove 6, the upper and lower surfaces of the connecting base layer 2 are both provided with positioning grooves 6, and the lower surface of the top base layer 3 is provided with a positioning groove 6.

[0034] Positioning blocks 7 are engaged in the positioning grooves 6 on the upper and lower surfaces of the base layer 2, and the base layer 2 is engaged in the positioning grooves 6 on the surfaces of the bottom base layer 1 and the top base layer 3 through the positioning blocks 7.

[0035] Positioning grooves 6 are made on the upper surface of the base layer 1, the upper and lower surfaces of the connecting base layer 2, and the lower surface of the top base layer 3. Positioning blocks 7 are installed in the positioning grooves 6 of the connecting base layer 2. When the base layers are stacked, the connecting base layer 2 is precisely engaged with the positioning grooves 6 of the base layer 1 and the top base layer 3 through the positioning blocks 7, forming a dual connection structure of "adhesive bonding + mechanical engagement". This dual fixing method greatly improves the interlayer connection strength. The adhesive layer 5 ensures tight adhesion between layers, and the engagement of the positioning grooves 6 and the positioning blocks 7 restricts the relative displacement between layers, jointly resisting the stress caused by temperature changes and humidity fluctuations. This solves the problem of easy delamination and warping of traditional single adhesive bonding, and enhances the structural stability of multilayer boards.

[0036] Example 3: This example is based on Example 1 and Example 2: Positioning holes 8 are provided on the outer surfaces of the four corners of the base layer 1, the connecting base layer 2 and the top base layer 3, and the positioning holes 8 penetrate the upper and lower surfaces of the four corners of the base layer 1, the connecting base layer 2 and the top base layer 3.

[0037] Protective corner plates 9 are installed at the four corners of the base layer 1, the connecting base layer 2 and the top base layer 3, and a connecting plate 10 is fixedly installed on the inner surface of the protective corner plate 9, and a positioning pin 11 is installed on the outer surface of the connecting plate 10.

[0038] The protective corner plate 9 is designed in an L-shape, and the outer surface of the protective corner plate 9 is flush with the outer surface of the bottom base layer 1, the connecting base layer 2 and the top base layer 3;

[0039] The positioning pin 11 is engaged with the positioning hole 8, and the lower end face of the positioning pin 11 is flush with the lower surface of the bottom base layer 1, and the upper end face of the positioning pin 11 is flush with the upper surface of the top base layer 3.

[0040] Positioning holes 8 are made at the four corners of the base layer 1, connecting base layer 2, and top base layer 3, penetrating the upper and lower surfaces. L-shaped protective corner plates 9 are installed at the four corners. The protective corner plates 9 are fixed to the positioning holes 8 by the connecting plate 10 and positioning pin 11 on the inner side.

[0041] The protective corner plate 9 uses an L-shaped structure to wrap around the four corners of the multilayer board, absorbing the impact force during transportation, installation and use, and avoiding damage to the edges and corners. At the same time, its outer side is flush with the base layer, so as not to affect the overall aesthetics. The positioning pin 11 passes through the positioning holes 8 of each layer, forming a longitudinal through-positioning of the bottom base layer 1, connecting base layer 2 and top base layer 3. It is bonded to the previous adhesive layer 5 and the positioning groove 6 and positioning block 7 are engaged to form a "triple fixation", which further improves the tightness and deformation resistance of the overall structure, effectively resists the influence of temperature and humidity changes, and solves the problems of easy damage to the edges and corners and insufficient overall stability of traditional multilayer boards.

[0042] 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.
