Another function of the limiting hook portion 36 is to support the main beam 1, making the assembly more compact.

[0054] Furthermore, the first side edge 21 and the second side edge 22 are respectively protruded in the shape of vertical bars on the adjacent corners of the column 2. More preferably, two groups of the first side edges 21 and the second side edges 22 are respectively protruded on the four corners of the column 2. The opposite surfaces of the column 2 of the present application are relatively provided with the first side edge 21 and the second side edge 22, wherein the positioning hanger 3 is clamped with the first side edge 21, the locking fastener 4 is engaged with the second side edge 22, and the positioning hanger 3 is locked on the column by the locking fastener 4.
