[0005] A composite board includes an upper composite panel, a middle board and a lower composite panel. The upper composite panel and the lower composite panel are fixed to the upper and lower surfaces of the middle board by a hot pressing and adhesive bonding process, respectively. A plurality of reinforcing pegs are arranged between the upper composite panel and the middle board and between the middle board and the lower composite panel. An adhesive composite buffer layer is formed between the upper composite panel and the middle board and between the middle board and the lower composite panel.

[0006] Preferably, the reinforcing peg includes a rubber block and a limiting plate fixed to both ends of the rubber block. A steel nail is fixed to the limiting plate, which is used to be nailed into the upper composite panel, the middle board or the lower composite panel. The limiting plate is used to limit the depth of the steel nail.

[0007] Preferably, the limiting plate is a hollow cylindrical rubber block.

[0008] Preferably, the length of the steel nail is not greater than one fourth of the thickness of the upper composite panel.

[0009] Preferably, the thickness of the upper composite panel and the lower composite panel is consistent.

[0010] Preferably, the thickness of the adhesive composite buffer layer is not less than two millimeters.

[0011] The utility model discloses a advantage and positive effect is: through adopting composite technology in the hot pressing process will reinforce peg and press into the board between, make the board between form a cavity for glue and latex filling and solidify here form a adhesive composite buffer layer, on one hand, the reinforcing peg effectively strengthens the connection between two layers of board, and the nail hole of steel nail also has the glue seepage and then strengthens the strength of adhesive, in addition to this under the cooperation of reinforcing peg and adhesive composite buffer layer form a good buffer layer, can form an effective buffer to human body in the use process, make the tread feeling more comfortable, in addition more mute, be applicable to horizontal and study room environment etc. BRIEF DESCRIPTION OF DRAWINGS
