In the present embodiment, the beams in the "beam cross-sectional direction" and the "beam length direction (beam axis direction)" all refer to the module beam. Wherein, because module roof beam in two directions of each multidirectional connecting piece 9 all welds down. Therefore, the definitions of the directions of the same outer table top surface 9-3, the same inner table top surface 9-2 and the same outer side surface 9-1 are all based on the module beam in one direction connected with the lower multidirectional connecting piece 9. Taking fig. 5 as an example, the reference beam direction of each outer mesa surface 9-3, each inner mesa surface 9-2, and each outer lateral surface 9-1 in the lower multi-directional connecting member 9 is the module beam in one direction corresponding thereto.
