As described above in detail with reference to the embodiments, according to the method for constructing a tower-like structure of the present invention, an existing outer cylinder having a roof temporarily installed at the top is installed, and the existing outer cylinder is installed. After extending the outer cylinder structure to a predetermined height by jacking up a predetermined amount and connecting the outer cylinder below it, install the existing inner cylinder inside the existing outer cylinder. Since the inner cylinder structure is extended to a predetermined height by jacking up a fixed amount and connecting the inner cylinder below it, it is not necessary to use a crane, etc. The erection work can be performed without being affected, and the work efficiency can be improved.

Further, according to the method for constructing a tower-like structure of the present invention, an existing outer cylinder is installed, the existing outer cylinder is jacked up by a predetermined amount, and the outer cylinder is connected below the outer cylinder to construct the outer cylinder structure. Since the objects are extended to a predetermined height and the horizontal beams stacked in the existing outer cylinder are sequentially mounted on the inner wall of the existing outer cylinder when jacking up, the horizontal beam mounting work can be performed at a low place. As a result, it is possible to improve safety.
