[0021] See Figure 1 and Figure 2 This utility model provides a lightweight, high-strength panel, including a substrate 1. Inwardly U-shaped rolled edges 11 are provided on both sides along the length of the substrate 1. A top panel 2 is provided along the upper surface of the substrate 1, covering the upper surface of the substrate 1. The substrate 1 is made of modified EPS material. Multiple connecting grooves 12 are provided on the surface of the substrate 1. A first connecting protrusion 21 matching the connecting grooves 12 is provided on the top panel 2. The substrate 1 and the top panel 2 are connected by an adhesive layer. The top panel 2 is made of calcium silicate board, tempered glass, or metal plate; the adhesive layer is adhesive mortar; the modified EPS material consists of an EPS material surface sequentially coated with a modified silicone resin layer and a cement slurry layer.

[0022] The connecting groove 12 can be provided through the length of the base 1. To prevent the upper panel 2 from loosening laterally, it can also be provided as a non-through structure. In order to improve the support performance of the bottom of the base 1, a lower panel (not shown in the figure) can be provided at the bottom of the base 1 and adapted to the bottom of the base 1. In order to improve the connection stability between the lower panel and the base, a connecting layer can be provided between the lower panel and the base 1. The connecting layer can be made of adhesive mortar, and the lower panel can be made of calcium silicate board, tempered glass or metal plate.

[0023] When preparing modified EPS materials, the EPS material needs to be foamed and filled into the corresponding mold in advance. By utilizing the air permeability of the material, the air inside can be removed by vacuuming and pressurizing, thereby improving the strength after molding and forming a preform with the same structure as the matrix 1. Then, a modified silicone resin layer and a cement slurry layer are wrapped in sequence to obtain the matrix 1, thereby further improving the strength of the matrix 1.

[0024] With the above structure, the overall weight of the panel can be reduced by the base 1 being made of modified EPS material. With the cooperation of the upper panel 2 and the U-shaped rolled edge 11, the upper panel 2 can be stably fixed on the base 1, and the support strength of the base 1 can be improved so as to support the items for a long time. With the cooperation of the first connecting protrusion 21 and the connecting groove 12, the contact surface between the base 1 and the upper panel 2 can be increased. At the same time, the stability of the upper panel 2 connected to the base 1 can be further improved by the connection of the connecting layer.

[0025] In one embodiment, see Figure 2 Multiple connecting grooves 12 are spaced apart along the width direction of the substrate 1, and the depth of the connecting grooves 12 is less than half the thickness of the substrate 1. In practical applications, the integrity of the substrate 1's own structure can be ensured by setting the connecting grooves 12.

[0026] The upper surface of the upper panel 2 is provided with a wear-resistant layer. In practical applications, the wear-resistant layer can improve the wear resistance, scratch resistance and stain resistance of the panel. The wear-resistant layer can be made of materials such as UV coating or PET film.

[0027] In one embodiment, see Figure 2 and Figure 4 The base 1 has frame 3 at both ends along its length. The frame 3 has grooves 31 for covering the end surfaces of the base 1 and the top panel 2. A second connecting protrusion 32 matching the connecting groove 12 is provided in the groove 31 of the frame 3. A clearance groove 13 adapted to the inner edge of the frame 3 is provided on the inner side of the U-shaped rolled edge 11. In practical applications, the frame 3 structure provides a covering effect for the base 1 and the top panel 2, further preventing the top panel 2 from sliding laterally relative to the base 1 and improving the overall aesthetics.

[0028] In one embodiment, see Figure 3 The base 1 has a first reinforcing rib 14 and a second reinforcing rib 15 arranged along its two diagonal sides. A third reinforcing rib 16 and a fourth reinforcing rib 17 are intersecting between the first and second reinforcing ribs 14 and 15. A fifth reinforcing rib 18 is arranged along the width of the base 1, passing through the intersection of the first and second reinforcing ribs 14 and 15. In practical applications, the cooperation of the first reinforcing ribs 14, 15, 16, 17, and 18 forms multiple triangular stable structures, thereby improving the overall strength of the base 1.

[0029] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
