PROBLEM TO BE SOLVED: To provide a cylindrical structure simple for a field work and having a coupling structure easy to modify an error in construction accuracy and a towering structure using this.;SOLUTION: There are provided: a first coupling plate which is fixed to a first and a second cylindrical members by a flange connection when the first and the second cylindrical members having an inner flange on each of the end surfaces are coupled in a serial direction, which is fixed to a third and a fourth cylindrical members by a flange connection when the third and the fourth cylindrical members having an inner flange on each of the end surfaces are coupled in a serial direction, and which is joined between a first and a second cylindrical structures when the first cylindrical structure consisting of the first and the second cylindrical members is connected in parallel with the second cylindrical structure consisting of the third and the fourth cylindrical members; and a shim ring having a predetermined thickness, arranged between an inner flange of any of the first to the fourth cylindrical members and the first coupling plate, and capable of modifying an error of the first and the second cylindrical structures in a serial direction.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
