After these basic members are formed and assembled into a core, the first frame layer is formed by laying a plurality of first frame battens 1, grooves 5 of each first frame batten 1 forming the first frame layer are all parallel (namely, the length direction or the wood fiber direction of all the grooves 5 of the first frame layer is the same), the second frame layer is formed by laying a plurality of second frame battens 2, the grooves 5 of the second frame layer are all parallel (namely, the length direction or the wood fiber direction of all the grooves 5 of the second frame layer is the same), the shear layer is formed by laying a plurality of shear battens 3, the grooves 5 of each shear batten 3 forming the shear layer are all parallel (namely, the length direction or the wood fiber direction of all the grooves 5 of the shear layer is the same), and then the first frame layer is assembled, The second frame layer and at least two shear layers are stacked and connected to form a multilayer structure 4, in the multilayer structure, the wood fiber directions of the first frame layer 1 and the second frame layer 2 are different (namely, the length directions of the grooves 5 on the two frame layers are different, and preferably, the length directions are mutually perpendicular), and the wood fiber directions of any two adjacent shear layers are opposite (namely, the length directions of the grooves 5 are opposite, and the opposite means that the length directions of the grooves 5 of the two shear layers are the same as the included angle of the long side or the wide side of the cuboid, but the included angles are different in orientation), and finally, the multilayer structures 4 are stacked and connected along the length direction of the plate core to form the plate core.
