ることができない。This type of chimney is composed of two self-standing cylinders having a height of 100 m or more, depending on the type and scale of a smoke source such as a boiler, and the location and environment in which the chimney is installed. It may be necessary to provide the body in a close arrangement. To cope with such a case, if a two-cylinder multi-leg structure is configured, the rigidity of the combined structure in a direction intersecting with a vertical plane passing through the axis of the two cylinder bodies is insufficient, and the height of the chimney exceeds 100 m. Therefore, it cannot withstand vibrations caused by external force such as wind.

There is a danger that the influence will be superimposed on the other one-cylinder free-standing chimney, causing unpredictable and complex vibration.
Conventionally, as shown in FIG.
There is a situation in which two single-cylinder chimneys of the size of 00 m must be installed at a safe distance from each other. SUMMARY OF THE INVENTION An object of the present invention is to provide a self-standing two-cylinder chimney capable of safely standing two high-rise cylinder bodies in close proximity to each other.
