Technical Field
[0001] This utility model relates to the field of board technology, specifically, to an eco-friendly board based on single mortise and tenon splicing. Background Technology
[0002] Ecological board, or melamine board, is a new type of interior decoration material that has become a major material in interior decoration. Ecological board is made by soaking paper with different colors or textures in resin, then drying it to a certain degree of curing, and then laying it on the surface of plywood, blockboard, etc., and hot pressing it to form a decorative board.
[0003] The existing eco-friendly boards have the following defects and shortcomings:
[0004] Firstly, regarding structural performance, existing eco-boards use a splicing method and rely on glue for bonding and fixing. This method cannot form a mechanical interlock at the joints, resulting in uneven stress distribution. Consequently, existing eco-boards cannot bear large loads at the glued joints and are prone to cracking at the flat joints.
[0005] Secondly, regarding stability, existing eco-boards are spliced together and fixed with glue, which lacks shear resistance. Since eco-boards are used in furniture, they are subject to dynamic load scenarios involving frequent disassembly and reassembly, and poor shear resistance leads to insufficient stability.
[0006] In addition, regarding the ability to resist deformation, the existing ecological boards use a splicing method and rely on glue for bonding and fixing, which cannot restrict the freedom between the boards. Ecological boards are prone to warping and deformation when affected by humidity.
[0007] Furthermore, the applicant has already designed a double tenon and mortise splicing scheme, but for different application scenarios of the board, such as the use of ecological board for cabinets, non-load-bearing partitions and block projects, it is necessary to consider the thickness of the material, lightweight design and flexibility factors, etc., and the double tenon and mortise splicing scheme cannot meet the above problems.
[0008] In summary, there is an urgent need for a single-mortise and tenon joint eco-board designed for various application scenarios, which offers good structural performance, stability, deformation resistance, and flexibility. However, no reports have yet been published regarding such an eco-board. Summary of the Invention
[0009] The purpose of this invention is to provide an eco-board with good structural performance, sufficient stability, good deformation resistance, and good flexibility, designed for the application scenarios of eco-boards.
[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0011] An eco-friendly board based on single mortise and tenon joints is disclosed. The eco-friendly board comprises sub-board strips and mother-board strips, with the transverse sides joined using mortise and tenon joints and the longitudinal sides joined using toothed joints. The upper transverse sides of both the sub-board strips and mother-board strips are provided with mortise and tenon protrusions; the lower transverse side of the sub-board strips is provided with mortise and tenon grooves. In the transversely joined state, the mortise and tenon protrusions of the sub-board strips engage with the fitting grooves of the mother-board strips; the mortise and tenon grooves of the sub-board strips engage with the fitting protrusions of the mother-board strips; both ends of both the sub-board strips and mother-board strips are provided with toothed mechanisms; the toothed mechanisms include alternating finger-shaped tenons and finger-shaped grooves; the two sides of the finger-shaped tenons are inclined; the finger-shaped tenons of the sub-board strips engage with the finger-shaped grooves of the mother-board strips; the finger-shaped grooves of the sub-board strips engage with the finger-shaped tenons of the mother-board strips.
[0012] As a preferred technical solution, both the sub-wooden strips and the mother-wooden strips are solid wood structures and are made of birch wood.
[0013] As a preferred technical solution, the ecological board further includes horizontal engineered wood veneer and vertical engineered wood veneer; and both the horizontal engineered wood veneer and the vertical engineered wood veneer are single-layer wood veneers.
[0014] As a preferred technical solution, both the sub-wooden strip and the mother-wooden strip have a clearance platform on one end of their toothed joint mechanism; and both the sub-wooden strip and the mother-wooden strip have thickened teeth on the other end of their toothed joint mechanism.
[0015] As a preferred technical solution, when the sub-wooden strip and the mother-wooden strip are longitudinally spliced, the thickened teeth of the mother-wooden strip abut against the clearance platform of the sub-wooden strip, and the tenon and mortise grooves on the sub-wooden strip are aligned with the tenon and mortise grooves on the mother-wooden strip.
[0016] As a preferred technical solution, both the sub-wooden strip and the mother-wooden strip have a limiting boss at one end of their tenon and mortise protrusions, and an inclined surface at the other end.
[0017] As a preferred technical solution, when the sub-wooden strip and the mother wooden strip are longitudinally spliced, the inclined surface of a tenon and mortise protrusion on the mother wooden strip abuts against the limiting protrusion of the tenon and mortise protrusion on the sub-wooden strip.
[0018] As a preferred technical solution, when the sub-wooden strip and the mother-wooden strip are horizontally spliced, the thickened teeth on the sub-wooden strip and the mother-wooden strip are located on the same side.
[0019] The advantages of this utility model are:
[0020] 1. The eco-board of this utility model adopts a single tenon and mortise splicing method, which has the advantages of higher process efficiency and better economy compared with the double tenon and mortise splicing scheme. The processing time of single tenon and mortise splicing can be shortened by 30%-50%, which is especially suitable for mass production and has lower requirements for equipment precision. Secondly, the reduction of grooving process can reduce labor and tooling costs. In addition, the single tenon and mortise splicing scheme reduces material removal, which is suitable for scenarios that need to reduce weight (such as hanging cabinets, movable furniture, etc.). Furthermore, the single tenon and mortise splicing scheme is particularly suitable for thin boards, which do not require greater board thickness for support and can be used stably in eco-boards with a thickness of less than 18mm, thus having a wider range of applications.
[0021] 2. The ecological boards are spliced longitudinally using a toothed joint method. The effect of this design is that the sub-board strips and the main board strips are fixed longitudinally by the toothed joint method. The toothed joint method greatly increases the splicing contact surface (compared to flat joint), resulting in stronger bonding force and better bending resistance after gluing. At the same time, the multiple teeth intersperse the internal stress of the board and prevent cracking.
[0022] 3. The eco-board also includes horizontal and vertical engineered wood veneers; both horizontal and vertical engineered wood veneers are single-layer veneers. The effect of this design is: by pasting horizontal and vertical engineered wood veneers, the main function is to increase the overall shear strength and longitudinal shear strength of the eco-board, resulting in good flatness and less susceptibility to deformation. Furthermore, the engineered wood veneer is a single layer, primarily because the core of the eco-board uses solid wood strips with horizontal mortise and tenon joints, eliminating any voids.
[0023] 4. Regarding the structural performance of the eco-board, the entire eco-board is constructed by interlocking multiple sub-board strips and mother-board strips using mortise and tenon joints, forming a mechanical interlock that distributes stress more evenly. The mortise and tenon joints can withstand greater loads and avoid the risk of cracking at the glued joints. Regarding stability, the eco-board uses a single mortise and tenon embedded design, which provides shear resistance and is particularly suitable for dynamic load scenarios, resulting in good stability. Regarding deformation resistance, the single mortise and tenon joints limit the freedom of movement between the boards, reducing warping and deformation.
[0024] 5. When the sub-wooden strip and the mother-wooden strip are joined, the thickened teeth of the sub-wooden strip abut against the clearance platform of the mother-wooden strip, and the mortise and tenon grooves on the sub-wooden strip are aligned with the mortise and tenon grooves on the mother-wooden strip. The effect of this design is that by setting a clearance platform and thickened teeth on the toothed joint mechanism, it ensures that the sub-wooden strip and the mother-wooden strip are aligned neatly during longitudinal splicing, so that the two strips form a straight line after splicing, avoiding misalignment in the longitudinal direction after splicing.
[0025] 6. One end of the tenon and mortise strip is provided with a limiting boss, and the other end is provided with an inclined surface. The effect of this design is that, through the design of the limiting boss, thickened teeth and inclined surface, the connection between the sub-wooden strips and the wood strips is more compact when splicing them longitudinally, reducing splicing gaps. At the same time, it has a guiding function, which can quickly match the toothed end of the sub-wooden strip with the appropriate toothed end of the mother wood strip, thereby improving the efficiency of installation.
[0026] 7. The cross-section of the mortise and tenon groove and the interlocking protrusion is an inverted trapezoidal structure. The effect of this design is that the inverted trapezoidal structure allows for a slight gap fit between the mortise and tenon protrusion that mates with the mortise and tenon groove, and the interlocking groove that mates with the interlocking protrusion. Furthermore, it provides space to compensate for the expansion and deformation of the eco-board when it is exposed to moisture, preventing cracking at the joints and overall warping.

[0061] It should be noted that the following is an explanation of this embodiment:
[0062] This utility model's eco-board uses a single mortise and tenon joint method, which, compared to the double mortise and tenon joint method, offers higher process efficiency and better economy. The single mortise and tenon joint reduces processing time by 30%-50%, making it particularly suitable for mass production and requiring lower equipment precision. Secondly, it reduces the grooving process, lowering labor and tooling costs. Furthermore, the single mortise and tenon joint method reduces material removal, making it suitable for applications requiring weight reduction (such as hanging cabinets and movable furniture). Moreover, the single mortise and tenon joint method is particularly suitable for thinner boards, eliminating the need for thicker boards and allowing for stable use in eco-boards less than 18mm thick, thus broadening its application range.
[0063] The aforementioned eco-board also includes horizontal and vertical engineered wood veneers 137; both horizontal and vertical engineered wood veneers 137 are single-layer veneers. The effect of this design is that by pasting the horizontal and vertical engineered wood veneers 137, the main function is to increase the overall shear strength and longitudinal shear strength of the eco-board, resulting in good flatness and reduced deformation. Furthermore, the engineered wood veneer 137 is a single layer, primarily because the core of the eco-board uses solid wood strips with horizontal mortise and tenon joints, eliminating voids. In contrast, existing eco-boards use glue for fixing, and in some areas, scrap materials are used for splicing, which easily leads to voids, necessitating the use of multiple layers of engineered wood veneer 137 to fill them, yet deformation still occurs.
[0064] Regarding the structural performance of the ecological board proposed in this application, the entire ecological board is constructed by interlocking multiple sub-wooden strips 1 and mother-wooden strips 4 in the transverse direction using mortise and tenon joints, forming a mechanical interlock that distributes stress more evenly. The mortise and tenon joints can withstand greater loads and avoid the risk of cracking at the flat joints.
[0065] Regarding stability, the ecological board in this application has shear resistance due to its single tenon-and-mortise embedded design, making it particularly suitable for dynamic load scenarios and exhibiting good stability.
[0066] Regarding the deformation resistance of the ecological board proposed in this application, the use of single tenon joints reduces warping and deformation by restricting the degree of freedom between the boards.
[0067] The ecological board is spliced longitudinally using a toothed joint method. The effect of this design is that the sub-board strip 1 and the mother door strip are fixed longitudinally by the toothed joint method. The toothed joint method greatly increases the splicing contact surface (compared to flat joint), resulting in stronger bonding force and better bending resistance after gluing. At the same time, the multiple teeth intersperse the internal stress of the board and prevent cracking.
[0068] The tenon and mortise protrusion 2 of the sub-wooden strip 1 mates with the fitting groove 6 of the mother-wooden strip 4; the tenon and mortise groove 3 of the sub-wooden strip 1 mates with the fitting protrusion 5 of the mother-wooden strip 4. The effect of this design is that the interlocking tenon and mortise structure transfers the stress point of the board from the glued surface in existing technologies to the physically interlocking surface, enhancing its resistance to bending, compression, and shearing. The structure is robust and not easily deformed. Furthermore, due to the tenon and mortise interlocking method, only a small amount of glue is needed for fixing, avoiding the problem of glue aging and failure, and resulting in good environmental performance.
[0069] Both the sub-wood strip 1 and the mother wood strip 4 have toothed joint mechanisms on their longitudinal left and right sides. These toothed joint mechanisms include finger-shaped tenons 81 and finger-shaped grooves 82. The finger-shaped tenons 81 of the sub-wood strip 1 engage with the finger-shaped grooves 82 of the mother wood strip 4; and the finger-shaped grooves 82 of the sub-wood strip 1 engage with the finger-shaped tenons 81 of the mother wood strip 4. The effect of this design is that by splicing in the longitudinal direction using a toothed joint, the bonding area is increased, resulting in stronger adhesion and better tensile and bending resistance after gluing. Furthermore, the multiple interlocking teeth between the finger-shaped tenons 81 and the finger-shaped grooves 82 disperse the internal stress of the wood, effectively resisting warping or cracking due to temperature changes.
[0070] The sub-wooden strip 1 has a clearance platform 10 on one end of its toothed joint mechanism; the other end of its toothed joint mechanism has a thickened tooth 9. Similarly, the mother wood strip 4 has a clearance platform 10 on one end of its toothed joint mechanism; the other end of its toothed joint mechanism has a thickened tooth 9. When the sub-wooden strip 1 and mother wood strip 4 are joined, the thickened tooth 9 of the mother wood strip 4 abuts against the clearance platform 10 of the sub-wooden strip 1, and the mortise and tenon groove 3 on the sub-wooden strip 1 is aligned with the mortise and tenon groove 3 on the mother wood strip 4. The effect of this design is that by setting the clearance platform 10 and the thickened tooth 9 on the toothed joint mechanism, it ensures that the sub-wooden strip 1 and mother wood strip 4 are aligned neatly when joined longitudinally, so that the two wood strips form a straight line after joining, avoiding misalignment of the two wood strips longitudinally after joining.
[0071] The tenon and mortise protrusion 2 of the sub-wooden strip 1 has a limiting boss 11 at one end and an inclined surface 12 at the other end; similarly, the tenon and mortise protrusion 2 of the mother-wooden strip 4 has a limiting boss 11 at one end and an inclined surface 12 at the other end. When the sub-wooden strip 1 and mother-wooden strip 4 are joined, the inclined surface 12 of one tenon and mortise protrusion 2 on the mother-wooden strip 4 abuts against the limiting boss 11 of the tenon and mortise protrusion 2 of the sub-wooden strip 1. The effect of this design is that, through the design of the limiting boss 11, the thickened teeth 9, and the inclined surface 12, the sub-wooden strip 1 and the wood strip are more tightly connected during longitudinal splicing, reducing splicing gaps. It also serves as a guide, enabling quick matching of the toothed end of the sub-wooden strip 1 with the appropriate toothed end of the mother-wooden strip 4, improving installation efficiency (because both the sub-wooden strip 1 and mother-wooden strip 4 have toothed mechanisms at both ends; without guidance on the splicing direction through processing details, incorrect splicing can easily occur, affecting the quality of the ecological board).
[0072] Both the sub-wood strip 1 and the mother wood strip 4 are solid wood structures, made of birch. The effect of this design is that the entire eco-friendly board is made of birch, has a solid wood structure, and is of high quality.
[0073] The cross-section of the mortise and tenon groove 3 and the fitting protrusion 5 is an inverted trapezoidal structure. The effect of this design is that the inverted trapezoidal structure allows for a slight gap between the mortise and tenon protrusion 2 (which mates with the mortise and tenon groove 3) and the fitting groove 5 (which mates with the fitting protrusion 5). Furthermore, it provides space to compensate for the expansion and deformation of the eco-board when it becomes damp, preventing cracking at the joints and overall warping.
[0074] When the sub-wooden strip 1 and the mother-wooden strip 4 are joined laterally, the thickened teeth 9 on the sub-wooden strip 1 and the mother-wooden strip 4 are located on the same side. The effect of this design is that the thickened teeth 9 guide the lateral joining direction, enabling rapid lateral joining while also taking into account longitudinal joining, ensuring the accuracy of the joining.
[0075] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several improvements and additions without departing from the principle of the present utility model, and these improvements and additions should also be considered within the protection scope of the present utility model.
