As shown in Fig. 6, the outer wall 4 of the upper flange plate of the work column 1 is provided with an outer wall 4, and the inner wall 3 is provided on both left and right sides of the upper flange plate. In this particular example, two single-ended connectors 5 and two double-ended connectors 6 are used.

The upper side of the work column 1 in Fig. 6 needs to be installed with an outer wall 4, and an inner wall is required at both the upper right corner and the upper left corner, and the single-ended connecting members 5 disposed at two places have a symmetrical structure.
