[0023] Furthermore, the column 3 is a rectangular parallelepiped as a whole, and the jacket 4 is fixed to the opposite side of the column 3 by welding. It should be noted that the jacket 4 is a semicircular plate as a whole, and a fixing hole is opened in the middle of the fixing block 401 which is symmetrically arranged horizontally and longitudinally. The position of the jacket 4 is fixed by the cooperation of bolts and nuts that pass through the symmetrically arranged jacket 4.
