Description

Technical Field

[0001] This utility model relates to the field of sheet metal technology, and more specifically, to a core board resistant to deformation. Background Technology

[0002] The most traditional and common core board is blockboard, which is a special type of plywood made by splicing wood boards or hollow boards as the core, covering both sides with plywood, and then pressing them together with glue. Compared with ordinary plywood, it is lighter, uses less glue, and has better environmental performance. At the same time, it can also present the texture of solid wood, satisfying consumers' psychological needs for solid wood furniture. As a new type of ecological board material, blockboard has been widely used in furniture manufacturing and interior decoration.

[0003] A search revealed that Chinese patent CN214027570U discloses an "anti-deformation core board," which is an integral board structure formed by stacking two veneers and a core board with corresponding length, width, and thickness directions along the thickness direction. The core board is located between the two veneers. The core board includes multiple core strips and multiple bamboo strips. The core strips and bamboo strips are connected between the upper and lower surfaces of the core board. All bamboo strips are spaced apart, and all core strips are distributed on the left and right sides of the bamboo strips. Adjacent core strips and adjacent core strips and bamboo strips are tightly stacked and joined without gaps along the left and right directions. The anti-deformation core board of this utility model has a simple structure. By replacing the original multi-layered horizontal wood with multiple vertically arranged core strips, it perfectly utilizes the principle of "a single piece of wood can support a thousand pounds," effectively improving the compressive strength and load-bearing capacity of the anti-deformation core board and solving the problem of poor compressive strength of existing plywood. This utility model is suitable for making cabinets, doors, and other cabinet doors, but it still has the following defects: The core strips and bamboo strips are seamlessly and tightly layered together. During long-term use, the adhesive may become unstable due to aging, which weakens the resistance to deformation. At the same time, under the influence of humidity and temperature changes, the difference in radial and tangential shrinkage rates of different wood strips will generate significant internal stress, which can easily lead to overall warping or cracking of the board, thereby reducing its dimensional stability in complex environments.

[0004] Therefore, a deformation-resistant core board is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a deformation-resistant core board to address the problem that existing adhesives may become unstable due to aging, thereby weakening their resistance to deformation.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a deformation-resistant core board, comprising a single board and a core board, wherein two sets of single boards are respectively stacked and joined to the top and bottom surfaces of the core board, and a reinforcing component for preventing deformation of the core board is inserted into one side of the core board. The reinforcing component includes a bamboo reinforcing sheet bonded to the top of the single board. A groove is provided on one side of the bamboo reinforcing sheet. A reinforcing rib is provided on one side of the core board. There are three sets of reinforcing ribs, and the reinforcing ribs are long strips extending along the length of the core board. The outer contour of the reinforcing rib matches the inner contour of the groove.

[0007] As a preferred technical solution of this utility model, a wooden core strip is bonded between the two sets of single boards and the wooden core strip is located on the other side of the core board. A stress relief groove for stress relief is formed between the wooden core strip and the core board.

[0008] As a preferred technical solution of this utility model, an elastic adhesive layer is provided in the stress relief groove formed by the wooden core strip and the core board, and the elastic adhesive layer is made of an elastic adhesive material.

[0009] As a preferred technical solution of this utility model, the core board has four sets of hollow cavities arranged in an array inside, and five sets of wooden core strips are evenly distributed between the two sets of veneers, and the wooden core strips are tightly attached to each other.

[0010] As a preferred technical solution of this utility model, the wooden core strip and the core board are arranged along both sides of the bamboo reinforcing sheet and are joined by an adhesive to form an integrated core layer structure, and the adhesive is MDI formaldehyde-free adhesive.

[0011] As a preferred technical solution of this utility model, the top and bottom of the core board are respectively stacked with a transverse constraint layer, the transverse constraint layer is oriented strand board, and the single board is joined to the core board through the transverse constraint layer.

[0012] As a preferred technical solution of this utility model, a flame-retardant layer is bonded to the other side of the single board, and an edge banding strip is embedded on the outer side of the core board, with the edge banding strip located on the inner side of the flame-retardant layer. The edge banding strip is made of a polymer composite material.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By incorporating reinforcing components, the core board's resistance to deformation is enhanced. While ensuring its resistance to deformation, production costs are not significantly increased. The combined design of reinforcing ribs and grooves further strengthens the overall structural stability of the core board, significantly improving its resistance to deformation and extending its service life. This allows the core board to maintain good shape and performance in various complex environments, effectively improving product quality and reliability.

[0014] 2. The wooden core strips significantly improve the core board's resistance to deformation and extend its service life. Even in complex and changing environments, the core board maintains good structural stability, reducing quality problems caused by deformation, lowering maintenance and replacement costs, and improving the overall performance and reliability of the product.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0018] Example: Figures 1-5 As shown, this embodiment proposes a deformation-resistant core board, including a single board 1 and a core board 2. The single board 1 consists of two sets, which are respectively stacked and joined to the top and bottom surfaces of the core board 2. A reinforcing component 3 for preventing deformation of the core board 2 is inserted into one side of the core board 2. The reinforcing component 3 includes a bamboo reinforcing sheet 301 bonded to the top of the veneer 1. A groove 302 is formed on one side of the bamboo reinforcing sheet 301, and reinforcing ribs 303 are provided on one side of the core board 2. There are three sets of reinforcing ribs 303, which are elongated strips extending along the length of the core board 2. The outer contour of the reinforcing ribs 303 matches the inner contour of the groove 302. In practical applications, when the core board 2 is subjected to external forces and may deform, the bamboo reinforcing sheet 301, with its high strength and firm bond to the top of the veneer 1, provides effective support. Simultaneously, the three sets of reinforcing ribs 303 on one side of the core board 2 are embedded in the groove 302, working in conjunction with the bamboo reinforcing sheet 301 to form a stable structural system. This ensures that when external forces act on the core board 2, they are evenly distributed to the bamboo reinforcing sheet 301 and the reinforcing ribs 303, rather than concentrated on the core board 2 itself, thus effectively resisting deformation caused by external forces.

[0019] like Figures 1-5 As shown, a wooden core strip 4 is bonded between two sets of veneers 1, and the wooden core strip 4 is located on the other side of the core board 2. A stress relief groove 5 is formed between the wooden core strip 4 and the core board 2 for stress release. The design of the stress relief groove 5 allows a certain buffer space to be formed between the wooden core strip 4 and the core board 2 when the core board 2 is subjected to external stress, thereby avoiding structural damage caused by stress concentration. In addition, the wooden core strip 4 itself has good flexibility and strength, and its bonding with the two sets of veneers 1 further enhances the overall structural stability of the core board 2. When the core board 2 is subjected to external forces of different directions and magnitudes, the wooden core strip 4 can work together with the bamboo reinforcing sheet 301 and the reinforcing rib 303 to reasonably disperse the external force with the help of the stress relief groove 5, effectively improving the deformation resistance of the core board 2 and thus extending its service life.

[0020] like Figures 2-5 As shown, an elastic adhesive layer 6 is provided within the stress relief groove 5 formed by the wooden core strip 4 and the core board. The elastic adhesive layer 6 is made of an elastic adhesive material. During operation, when the core board 2 is subjected to external force and generates stress, the wooden core strip 4 and the core board will tend to shift relative to each other due to the stress. At this time, the elastic adhesive layer 6, with its own elastic properties, can deform to a certain extent, absorbing and buffering this stress, preventing the stress from acting directly on the core board 2 and the wooden core strip 4, and preventing them from deforming or being damaged due to stress concentration.

[0021] like Figures 1-5As shown, the core board 2 has four sets of hollow cavities 7 arranged in an array inside, and five sets of wooden core strips 4 are evenly distributed between the two sets of veneers 1, with each set of wooden core strips 4 tightly fitted together. Each set of hollow cavities 7 is spaced apart from the adjacent wooden core strips 4. This layout not only reduces the overall weight of the core board 2, but also provides it with good heat insulation and sound insulation performance. The wooden core strips 4 ensure that when the core board 2 is subjected to external forces, the stress can be evenly distributed to each wooden core strip 4, further enhancing the core board 2's resistance to deformation.

[0022] like Figures 2-5 As shown, the wooden core strips 4 and the vertical core board 2 are arranged along both sides of the bamboo reinforcing sheet 301 and are joined together by an adhesive to form an integrated core structure. The adhesive is MDI formaldehyde-free adhesive. This integrated core structure design makes the connection between the vertical core board 2 and the wooden core strips 4 more stable, effectively improving the overall structural stability. The use of MDI formaldehyde-free adhesive not only ensures the strength and durability of the joint but also avoids harmful substances such as formaldehyde that may be contained in traditional adhesives, making the vertical core board 2 more environmentally friendly and healthy, meeting the needs of modern green building and furniture manufacturing.

[0023] like Figures 1-5 As shown, the top and bottom of the core board 2 are respectively stacked with transverse constraint layers 8, which are oriented strand board (OSB). The veneer 1 is joined to the core board 2 through the transverse constraint layers 8. The transverse constraint layers 8 can effectively limit the deformation of the core board 2 in the transverse direction, ensuring that it can provide strong support when subjected to transverse external forces, preventing the core board 2 from bending or twisting excessively, thereby significantly improving its deformation resistance.

[0024] like Figures 1-3 and Figure 5 As shown, a flame-retardant layer 9 is bonded to the other side of the single-layer board 1, and an edge banding strip 10 is embedded on the outer side of the core board 2, with the edge banding strip 10 located inside the flame-retardant layer 9. The edge banding strip 10 is made of a high-polymer composite material. The edge banding strip 10, made of high-polymer composite material, has excellent wear resistance and corrosion resistance, effectively protecting the edges of the core board 2 and preventing damage from collisions or friction during use. The flame-retardant layer 9 further enhances the fire resistance of the core board 2, enabling it to quickly stop the spread of fire when exposed to a fire source, providing strong protection for the safety of buildings and furniture.

[0025] Working Principle: This utility model provides a deformation-resistant core board. The specific usage steps are as follows: Step 1: When the core board 2 is subjected to external force and may deform, the bamboo reinforcing sheet 301, with its high strength and firm adhesion to the top of the veneer 1, can provide effective support. At the same time, the three sets of reinforcing ribs 303 on one side of the core board 2 are embedded in the groove 302, working together with the bamboo reinforcing sheet 301 to form a stable structural system. This allows the external force acting on the core board 2 to be evenly distributed to the bamboo reinforcing sheet 301 and the reinforcing ribs 303, rather than concentrated on the core board 2 itself, thereby effectively resisting deformation caused by external force. Step 2: The design of the stress relief groove 5 allows the core board 2 to form a certain buffer space between the wooden core strip 4 and the core board 2 when it is subjected to external stress, thereby avoiding structural damage caused by stress concentration. In addition, the wooden core strip 4 itself has good flexibility and strength, and its bonding with the two sets of veneers 1 further enhances the overall structural stability of the core board 2. When the core board 2 is subjected to external forces of different directions and magnitudes, the wooden core strip 4 can work together with the bamboo reinforcing sheet 301 and the reinforcing rib 303 to reasonably disperse the external force with the help of the stress relief groove 5, effectively improving the deformation resistance of the core board 2 and thus extending its service life.

[0026] All technical features in this embodiment can be freely combined according to actual needs.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
