するものである。 Therefore, the present invention proposes a method for constructing a tower-supported chimney that solves these problems, and its features include assembling the legs of the steel tower at predetermined locations, and installing the leading cylinder inside the legs. A push-up device is installed in accordance with the position, and the first to a predetermined number of stages of the preceding barrel are arranged on the push-up device in this leg, and the adjacent barrels are stacked and arranged from the lowest step to a predetermined number of steps in the leg. A jib crane is placed in the first stage of the leading barrel, and this jib crane lifts and supports the post to which the boom is attached within the first stage, fixes it to the first stage with a fixing device, and lifts the post with the boom into the first stage. Push up the barrel to a specified height, insert the next lower tier under it, use the jib crane to lift the next upper tier of the adjacent barrel and stack it on top of the stacked tier, and then use the jib crane to lift the second tier from the steel tower. Assemble on the legs, repeat the above steps, stack both barrels as specified except for the bottom of the leading barrel, assemble the steel tower, lift the nozzle part with a jib crane,
Each nozzle part is arranged at the top of both barrels, and the jib crane is lowered through the leading barrel, taken out of the leading barrel through the space at the bottom, and the lowermost stage is inserted into that space. In particular, according to this configuration, the stability of the crane is increased by installing the crane on the leading barrel, the above-mentioned problems are solved, and the construction is excellent in safety and workability, and at low cost. This provides a method by which this can be done.
