<P>PROBLEM TO BE SOLVED: To provide an assembling device stably supportable even if the device is set up high in the device for assembling a columnar structure such as wind power generation equipment without using a large crane. <P>SOLUTION: A portal frame 3 is successively forced up by a forcing-up device 2, and unit columns 8a and 8b are added downward, and are extended upward according to progress. A rope 5 extended to a pulley 4 of the portal frame 3 is wound up by a winch 6, and since tower units T1 and T2 are successively set upward by this winch, a tower can be efficiently constructed without using the large crane. A tower guide 19 is stably supported by the tower units T1 and T2 of already uplifting an extension midway part of a column body 8. Since the tower guide 19 is freely engageable/separable to the column body 8 by an engaging member 25, the guide is forced up together with the column body 8 or is stationed on the spot, and only the column body 8 can be forced up. <P>COPYRIGHT: (C)2004,JPO |
