Abstract: Disclosed is a board core of an artificial board, the board core comprising a plurality of groups of core strip units (5), wherein each of the core strip units has a multi-layer structure in the lengthwise direction of a board core; each of the core strip units comprises multiple substrates; each of the substrates comprises a vertical pressure-bearing body (2) extending in the thickness direction of the board core, a horizontal pressure-bearing body (1) extending in the lengthwise direction of the board core, an oblique pulling structure (3) obliquely arranged with respect to the horizontal pressure-hearing body and the vertical pressure-hearing body, and a dual-horizontal pressure-bearing body (12) extending, in the lengthwise direction of the board core; and each of the core strip units is formed by means of sequentially arranging the multiple substrates, and different substrates form different core strip unit structures.
