DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1 and 2 , the present utility model provides a double-sided anti-deformation plywood, including a plywood substrate 1, a second anti-deformation frame plate 5, a plywood upper panel 12, a protective frame 18 and a double-sided anti-deformation component. On the upper and lower sides of the plywood substrate 1 are a second anti-deformation frame plate 5 and a first anti-deformation frame plate 4. Inside the second anti-deformation frame plate 5 is connected a reinforcement bracket 8. On both sides of the reinforcement bracket 8 are arranged double-sided anti-deformation components for preventing the plywood from deforming. The outer side of the plywood substrate 1 is movably clamped inside the inner wall of the protective frame 18. On the upper and lower sides of the protective frame 18 are respectively clamped a plywood upper panel 12 and a plywood lower back panel 13. The plywood upper panel 12 and the plywood lower back panel 13 are installed on both sides of the plywood substrate 1 through rubber columns 15.

[0027] In this embodiment, through the cooperative setting of structures such as the plywood substrate 1, the second anti-deformation frame plate 5, the plywood upper panel 12, the protective frame 18 and the anti-deformation component, the anti-deformation ability of the plywood can be effectively improved, the effect of the plywood on the double-sided anti-deformation ability can be improved, and at the same time, the high-strength performance of the plywood can be ensured.

[0028] In a further preferred embodiment, as Figure 3 and 4 shown, the double-sided anti-deformation component includes: a mounting frame 9 connected to the inner wall of the second anti-deformation frame plate 5, and an anti-deformation frame 10 installed inside the mounting frame 9. Among them, a connecting frame 11 is connected to the inner wall of the mounting frame 9, and one end of the connecting frame 11 is fixedly connected to the surface of the anti-deformation frame 10.

[0029] Among them, the second anti-deformation frame plate 5 is a structure for assembling and protecting the edges of the double-sided anti-deformation structure of the plywood. The mounting frame 9 is a structure for restricting the anti-deformation frame 10 and the connecting frame 11, and cooperating with the anti-deformation frame 10 and the connecting frame 11 to improve the structural stability of the plywood. The connecting frame 11 is a structure for stably connecting the anti-deformation frame 10 and the mounting frame 9, ensuring the compressive and anti-deformation ability of the structure.

[0030] Fixing frames 6 are provided at the four inner corners of the first anti-deformation frame plate 4 and the second anti-deformation frame plate 5. Positioning holes 2 are formed on the surface of the plywood substrate 1, and through holes matching the positioning holes 2 are formed on the surface of the fixing frames 6. Circular grooves 14 are formed on the surfaces of the upper plywood panel 12 and the lower plywood back panel 13. Rubber columns 15 are installed inside the circular grooves 14, and the rubber columns 15 are inserted into the inner walls of the fixing frames 6 and the positioning holes 2 through the circular grooves 14. Limiting discs 16 are connected to both ends of the rubber columns 15. The limiting discs 16 are arranged on the inner wall of the circular groove 14, and the end surfaces of the limiting discs 16 are flush with the outer surface of the upper plywood panel 12.

[0031] Furthermore, the first anti-deformation frame plate 4 has the same structure as the second anti-deformation frame plate 5. The first anti-deformation frame plate 4 and the second anti-deformation frame plate 5 are respectively installed on the upper and lower surfaces of the plywood substrate 1. The fixing frame 6 is structured to cooperate with the positioning hole 2, which can facilitate the assembly and fixation of the upper plywood panel 12 and the lower plywood back panel 13 together through the rubber columns 15, and the limiting disc 16 has an anti-loosening effect.

[0032] In addition, as Figure 4 shown, limiting grooves 3 are formed on the outer side of the plywood substrate 1. Positioning blocks 19 are distributed on the inner wall of the protective frame 18, and the surface of the positioning blocks 19 is clamped on the inner wall of the limiting grooves 3. Card slots 7 are formed on the outer surfaces of the first anti-deformation frame plate 4 and the second anti-deformation frame plate 5, and the inner walls of the card slots 7 are clamped at both ends of the positioning blocks 19. Annular clamping frames 20 are provided on the upper and lower surfaces of the protective frame 18. Sealing grooves 17 are respectively formed on the end faces of the upper plywood panel 12 and the lower plywood back panel 13, and the surface of the annular clamping frame 20 is hermetically clamped on the inner wall of the sealing groove 17.

[0033] In addition, the plywood substrate 1 is a limiting structure that is clamped with the positioning block 19 by the limiting groove 3. The card slot 7 is a structure in which the second anti-deformation frame plate 5 cooperates with the positioning block 19. The protective frame 18 can perform edge wrapping and protection on the plywood substrate 1, the first anti-deformation frame plate 4 and the second anti-deformation frame plate 5. The annular clamping frame 20 is a clamping structure that cooperates with the upper plywood panel 12 and the lower plywood back panel 13.

[0034] It should be noted that, as Figure 5 and 6 shown, reinforcing compressive layers 23 are provided on the inner walls of the upper plywood panel 12 and the lower plywood back panel 13. A flame retardant layer 24 is adhesively bonded to the bottom of the reinforcing compressive layer 23, and a protective plate layer 21 is provided on the top of the reinforcing compressive layer 23. A waterproof layer 22 is provided between the protective plate layer 21 and the reinforcing compressive layer 23, and the waterproof layer 22 is adhesively bonded to the protective plate layer 21 and the reinforcing compressive layer 23.

[0035] Furthermore, the compression-resistant layer 23 is used to improve the compression resistance of the upper plywood panel 12 and the lower plywood back panel 13 of the plywood. A high-strength steel fiber mesh can be used to improve the overall anti-deformation ability of the plywood. The waterproof layer 22 functions to prevent water and moisture, reduce the influence of water stain corrosion and moisture on the structural stability, and improve the service life of the structure. The flame-retardant layer 24 reduces the occurrence of plywood combustion and is a material that can inhibit or delay combustion and is not easily combustible itself.

[0036] By placing the plywood substrate 1 on the top of the first anti-deformation frame plate 4, clamping the protective frame 18 around the plywood substrate 1 and the first anti-deformation frame plate 4 through the positioning blocks 19, assembling the second anti-deformation frame plate 5 on the top of the plywood substrate 1 and clamping it with the positioning blocks 19, finally clamping the upper plywood panel 12 and the lower plywood back panel 13 on the upper and lower surfaces of the assembled plywood substrate 1 respectively, bonding and pressing the connection parts, and finally fixing and restricting the plywood by the rubber columns 15 and the limit discs 16, the strength and the two-way anti-deformation ability of the plywood structure are improved. The waterproof and flame-retardant effects of the plywood can be further improved through the waterproof layer 22 and the flame-retardant layer 24, ensuring the service life of the plywood.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
