Next, a bracket 10 is respectively fastened inside the four lower main column materials 5b in the separation part J by bolts. An upper side segment 2 is supported by its bracket 10, and the joint bolt of the separation part is wholly extracted, and afterwards, two sets of upper main column materials 5a of a diagonal position are drawn in the mutually approaching direction by a pulling tool 13 up to releasing taper fitting with the lower main column materials 5b. In this state, a suspension wire 6 installed in advance on an upper side segment 2 of a tower body is hooked on a hook 16 suspended from the helicopter 15, and the upper side segment 2 is lifted.;COPYRIGHT: (C)2007,JPO&INPIT
