[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] In the description of the utility model, it is understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is the orientation or positional relationship shown based on the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0029] Please refer to Figures 1-4 , a kind of high-strength foam plastic board, including two upper and lower symmetrical core layer one 1 and core layer two 2, it is equipped with an anti-distortion frame 3 between core layer one 1 and core layer two 2, core layer one 1 is arranged in the upper portion of core layer two 2, and an outer cover sheet 4 is also provided on the upper end surface of core layer one 1, a lower cover sheet 5 is provided on the lower end surface of core layer two 2, a bearing layer 6 is provided on the lower end surface of lower cover sheet 5;

[0030] Multiple hexagonal structure penetrating honeycomb holes 7 are provided on core layer one 1 and core layer two 2, mounting grooves 8 for mounting anti-distortion frame 3 are provided on the lower end surface of core layer one 1, and a mounting groove 8 is also provided on the upper end surface of core layer two 2, the depth of mounting groove 8 is half of the thickness of anti-distortion frame 3, and a wear-resistant layer 9 is also provided on the upper end surface of outer cover sheet 4 by spraying process.

[0031] Specifically, the core layer one 1 and the core layer two 2 are both made of polystyrene foam, and the thickness of each is 5mm. Polystyrene foam has the advantages of light weight, heat insulation, sound insulation, etc., and is the main supporting structure of foam plastic board. A plurality of hexagonal structure penetrating honeycomb holes 7 are arranged on the core layer, and the coverage rate is not less than 70%. This honeycomb structure not only further reduces the weight of the core layer, but also effectively disperses external force and improves the compression resistance of the core layer. When the foam plastic board is subjected to vertical pressure, the structure of the honeycomb hole 7 can make the pressure evenly distributed on the entire core layer, avoiding damage caused by local stress concentration.

[0032] The core layer one 1 and the core layer two 2 are arranged symmetrically, providing a stable internal support structure for the entire foam plastic board. They cooperate with the anti-twist frame 3 to jointly bear external pressure and twisting force. At the same time, the core layer provides an attachment base for the outer cover sheet 4 and the lower cover sheet 5, ensuring that the cover sheets can be firmly fixed on the core layer.

[0033] Specifically, the outer cover sheet 4 and the lower cover sheet 5 are both made of glass fiber reinforced plastic. Glass fiber reinforced plastic has the characteristics of high strength and high modulus, which can provide good protection for the foam plastic board, prevent the core layer from being directly damaged by external friction, impact, etc., and enhance the overall durability.

[0034] Specifically, the anti-twist frame 3 is connected with the mounting slot 8 on the core layer one 1 and the core layer two 2. This connection method makes the anti-twist frame tightly embedded in the core layer, effectively enhancing the anti-twist performance of the foam plastic board. When subjected to external twisting force, the anti-twist frame can bear most of the twisting force, protecting the integrity of the core layer structure.

[0035] Specifically, the thickness of the lower cover sheet 5 is less than that of the outer cover sheet 4. According to the actual use scenario, the outer cover sheet 4 on the top faces more direct friction and collision risks, and a thicker design can provide better protection. The lower cover sheet 5 mainly serves as an auxiliary protection and connection to the bearing layer, and a slightly thinner design does not affect the overall performance and can save costs.

[0036] Specifically, the bearing layer 6 is made of rubber material, and its thickness is 3-5mm and the hardness is between Shore A 70-80. The rubber material bearing layer 6 has good elastic buffering performance, which can absorb part of the impact force when the foam plastic board is carrying heavy objects, protecting the internal structure. The appropriate thickness and hardness can not only ensure the buffering effect, but also maintain certain bearing stability.

[0037] Specifically, the anti-twist frame 3 is made of aluminum alloy 6061-T6. Aluminum alloy 6061-T6 has high strength, good toughness and corrosion resistance, providing reliable anti-twist support for the foam plastic board, ensuring that the structure does not deform severely in complex stress environment.

[0038] Specifically, the wear-resistant layer 9 is arranged on the upper end surface of the outer cover sheet 4 by using a two-component polyurethane coating through a spraying process. After curing, the two-component polyurethane coating forms a tough wear-resistant coating, greatly improving the wear resistance of the outer cover sheet 4 and even the entire foam plastic plate, prolonging the service life, and adapting to high-friction use scenarios.

[0039] Specifically, the lower end surface of the outer cover sheet 4 is also provided with a plurality of anti-expansion grooves 10. When the ambient temperature and humidity change, the foam plastic plate is prone to expansion and deformation. The anti-expansion grooves 10 can effectively release internal stress, prevent structural cracking and damage caused by excessive expansion, and ensure the stability of the overall structure.

[0040] The details of the embodiments, and in the spirit or basic characteristics of the present application without departing from the scope of the present application, can be realized in other specific forms. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0041] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity. The skilled person should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by the skilled person.
