The second wear-resistant layer 5 and the first wear-resistant layer 7 are used to make the interior and surface of the entire multilayer board have wear-resistant properties, thereby increasing the wear-resistant effect of the entire multilayer board. The wear-resistant filler layer 12 is applied to the joints of the multilayer board. On the one hand, the joint gaps of the multilayer board are sealed, and on the other hand, the joint gaps can be wear-resistantly treated, thereby fully improving the wear resistance of the entire multilayer board.

[0024] Specifically, the core board layer 1 is composed of multiple core blocks 101, and the core blocks 101 are fixed by hot pressing and gluing. A first card slot 102 is opened at one end of the bottom of the core block 101, and a second card slot 103 is opened at the other end of the top of the core block 101. The second card slot 103 is snap-fitted with the first card slot 102, so that the first card slot 102 and the second card slot 103 are snap-fitted, thereby ensuring the fastening performance between two adjacent multilayer boards.

[0025] Specifically, multiple rows of equally spaced vertical holes 8 are provided on the core board layer 1 and the solid wood veneer layer 4, and equally spaced transverse holes 9 are provided between the two ends of the core board layer 1, and the transverse holes 9 are connected to the vertical holes 8.
