The column is connected and fixed by connecting bolts passing through the connecting hole a and the connecting hole A.

[0022] A gap is left between the outer side of the connecting plate a41 and the corresponding edge of the top plate 43. Each connecting plate a41 has three equally spaced stiffening plates a42 on its outer side. The two connecting holes a on each connecting plate a41 are located in the two gaps formed by the three stiffening plates a42. The function of the stiffening plates a42 is to reinforce and stabilize the connecting plate a41 and prevent it from deforming under stress.
