[0004] The purpose and effect of this utility model of a foam board with high compressive strength are achieved by the following specific technical means:

[0005] A high-compression-resistant foam board includes a foam board body with a three-layer structure. The three layers, from the inside out, are a support layer, a compression-resistant layer, and a rodent-proof layer. The support layer and the compression-resistant layer are connected by a serrated interlocking interface, with the serrations evenly distributed along the length direction. The compression-resistant layer and the rodent-proof layer are bonded together by an adhesive layer, which has evenly distributed through holes. A protective layer covers the foam board body.

[0011] According to a preferred embodiment, the protective layer is a thin sheet of iron, and the protective layer has multiple sets of vent holes. The multiple sets of vent holes are evenly distributed along the length of the sidewall of the pressure-resistant layer.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the honeycomb support frame embedded in the foam matrix within the support layer, and the arrangement of multiple sets of support rods and trapezoidal reinforcing ribs along the width direction within the compression-resistant layer, enables users to obtain a foam board with high-strength support, thus improving the device's compressive strength.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0022] Example:

[0023] like Figures 1 to 4 As shown, this utility model provides a foam board with high compressive strength, including a foam board body with a three-layer structure. From the inside out, the three layers are a support layer 11, a compressive strength layer 12, and a rodent-proof layer 13. This three-layer structure ensures the performance of the foam board from multiple aspects, including internal support, external compressive strength, and rodent prevention, thus improving the overall performance of the device. The support layer 11 and the compressive strength layer 12 are connected by a serrated interlocking interface, with the serrations evenly distributed along the length. This serrated interlocking interface enhances the connection stability between the support layer 11 and the compressive strength layer 12, preventing misalignment under stress and improving the structural stability of the device. The pressure-resistant layer 12 and the rodent-proof layer 13 are bonded together by an adhesive layer 16, which contains evenly distributed through-holes 17. The adhesive layer 16 and its through-holes 17 enable the bonding of the pressure-resistant layer 12 and the rodent-proof layer 13. The through-holes 17 can be filled with elastic particles 18 to enhance cushioning capacity, thus improving the interlayer bonding strength and cushioning performance of the device. A protective layer 19 covers the foam board body. This protective layer 19 protects the internal support layer 11, pressure-resistant layer 12, and rodent-proof layer 13 from external physical damage and chemical corrosion, improving the device's durability.

[0024] The support layer 11 includes a foam matrix 22 and a support frame 23. The support frame 23 is honeycomb-shaped, and the foam matrix 22 is embedded within the support frame 23. Through the arrangement of the honeycomb-shaped support frame 23 and the foam matrix 22 embedded within it, the device can utilize the mechanical properties of the honeycomb structure to provide good internal support for the foam board, disperse pressure, and improve the compressive strength of the device.

[0025] The compression-resistant layer 12 is provided with multiple sets of support rods 24, and multiple sets of trapezoidal reinforcing ribs 25 are provided on the compression-resistant layer 12, with the trapezoidal reinforcing ribs 25 arranged along the width direction. Through the arrangement of multiple sets of support rods 24 and trapezoidal reinforcing ribs 25 arranged along the width direction, the device can form a support structure inside the compression-resistant layer 12, further enhancing the compression-resistant layer 12's ability to resist external pressure and improving the device's compressive strength.

[0026] like Figure 3 , 4 As shown, the bottom of the serrated engagement interface has a hemispherical groove 15, and the top of the serrated engagement interface has a hemispherical protrusion 14, which is engaged within the hemispherical groove 15. The engagement of the hemispherical protrusion 14 at the top of the tooth and the hemispherical groove 15 at the bottom of the tooth further increases the friction and engagement force at the connection between the support layer 11 and the pressure-resistant layer 12, preventing relative sliding of the two layers under stress and improving the reliability of the structural connection of the device.

[0027] The adhesive layer 16 is an epoxy resin adhesive. By using the epoxy resin adhesive, the device can bond the pressure-resistant layer 12 and the rodent-proof layer 13 together with its good bonding performance, thereby improving the reliability of the interlayer bonding of the device.

[0028] The through-holes 17 of the adhesive layer 16 are filled with elastic particles 18, which are made of silicone rubber. By setting the silicone rubber elastic particles 18, the device can absorb energy by the elastic deformation of the elastic particles 18 when subjected to external impact, thereby playing a role in buffering and shock absorption and improving the impact resistance of the device.

[0029] The rodent-proof layer 13 is made of polyethylene substrate mixed with organophosphorus rodent repellent, and a protective mesh 26 is provided on the rodent-proof layer 13. By combining the polyethylene substrate with organophosphorus rodent repellent and the protective mesh 26, the device can prevent rats from corroding the foam board, extend the service life of the foam board, and improve the rodent-proof capability of the device.

[0030] like Figure 1 As shown, the protective layer 19 is a thin sheet of iron, and multiple sets of ventilation holes 21 are formed in the protective layer 19. These ventilation holes 21 are evenly distributed along the length of the sidewall of the compression-resistant layer 12. Through the thin sheet of iron protective layer 19 and its evenly distributed ventilation holes 21, the device can protect the internal structure of the foam board while ensuring air circulation, preventing mold and deterioration caused by moisture accumulation, thus improving the applicability of the device in different environments.

[0031] The specific usage and function of this embodiment are as follows:

[0032] When installing or using the foam board, the support layer 11 and the pressure-resistant layer 12 are connected by a serrated interlocking interface. The serrations are evenly distributed along the length direction, and the hemispherical protrusions 14 at the top of the serrations engage with the hemispherical grooves 15 at the bottom of the serrations. This connection method enhances the stability of the connection between the two layers. Under external force, the serrated interlocking interface can resist shear forces parallel to the layer, while the cooperation between the hemispherical protrusions 14 and the hemispherical grooves 15 further prevents the two layers from separating or sliding in the vertical direction, ensuring the structural stability of the foam board under pressure and improving the stability and reliability of the device structure. The pressure-resistant layer 12 and the rodent-proof layer 13 are composited by an epoxy resin adhesive layer 16 containing uniformly perforated holes 17, and the perforated holes 17 are filled with silicone rubber elastic particles 18. The epoxy resin adhesive has high-strength bonding performance, bonding the pressure-resistant layer 12 and the rodent-proof layer 13 together. The silicone rubber elastic particles 18 in the perforated holes 17 undergo elastic deformation when subjected to external impact, absorbing and dispersing the impact force, thus playing a buffering role. This not only enhances the connection stability between the two layers but also improves the overall impact resistance of the foam board, enabling it to better protect the internal structure when subjected to external impacts and improving the impact resistance and interlayer bonding strength of the device. The foam matrix 22 within the support layer 11 is embedded within the honeycomb support frame 23, providing support to the foam board as a whole. The honeycomb support frame 23 has excellent mechanical properties, capable of uniformly distributing pressure in all directions. The foam matrix 22 fills within it, ensuring a certain level of cushioning performance while enhancing the overall support capacity through the honeycomb structure. This structure allows the foam board to effectively disperse pressure when subjected to stress, avoiding deformation or damage caused by localized stress concentration, and improving the device's compressive strength. Multiple sets of support rods 24 within the compressive layer 12 are arranged in a specific pattern, working in conjunction with multiple sets of trapezoidal reinforcing ribs 25 arranged along the width direction. The multiple sets of support rods 24 provide vertical support to the compressive layer 12, enhancing its ability to resist vertical pressure.

[0033] The trapezoidal reinforcing ribs 25 arranged along the width direction enhance the bending resistance of the compression layer 12 in the horizontal direction. Together, they enhance the overall compressive strength of the compression layer 12 from different directions, enabling the foam board to withstand pressure from all directions and significantly improving the compressive strength of the device. The rodent-proof layer 13 is made of polyethylene substrate mixed with organophosphorus rodent repellent and has a protective mesh 26 on its surface. This rodent-proof layer 13 functions when the foam board is used in environments where it may be susceptible to rodent gnawing. The polyethylene substrate provides a stable carrier for the organophosphorus rodent repellent, which repels and inhibits rodent gnawing. The protective mesh 26 further prevents rodents from directly contacting the foam board, providing double protection against rodent damage, extending the lifespan of the foam board, and improving the device's rodent-proof capability. The thin sheet metal protective layer 19 covering the foam board body has multiple sets of ventilation holes 21 evenly distributed along the length of the sidewall of the compression layer 12. This protective layer 19 functions in various operating environments, especially in environments where moisture accumulation may occur. The thin iron sheet protective layer 19 has a certain strength and hardness, which can resist external physical damage such as scratches and collisions. The evenly distributed vents 21 ensure the circulation of air inside the foam board, allowing internal moisture to be discharged in time, avoiding problems such as mold and deterioration caused by moisture accumulation, improving the applicability of the device in different environments, and extending the service life of the foam board.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
