PROBLEM TO BE SOLVED: To provide a method for assembling divided annular tubes with which the annular tube setting work to a blast furnace can be simplified, and to provide a supporting structure of the assembled annular tube with this assembling method. SOLUTION: This assembling method is performed as the followings, that is, the plurality of divided annular tubes 21 are united and fastened and combined at a workshop before carrying into a fitting site, and a temporary assembled annular tube 20 under supporting state for using positions of the hang-up parts 26 at the setting site, as the supporting points, is formed, and after measuring the strain 24 appeared in the temporary assembled annular tube, this one is again disassembled, and when assembled as the annular tube at the fitting site and hung up, the hang-up parts are hung up to the right above and this assembled tube is fixed as it is. The supporting structure for annular tube set to the fitting position with the assembling method, is the one, with which the above supporting points 26 for annular tube are hung up to a blast furnace scaffold and two points of both sides of each supporting point, are connected with a blast furnace scaffold supporting strut 16.
