持型煙突を架設する。The low-rise tower part (2) is erected to a height before the range H in which it can be erected by the truck crane (1). (See FIG. 1) Next, a hoisting wire (3) is charged at the top of the steel tower portion (2), and a cylindrical block (4) is hoisted. (Second
Then, as shown in FIG. 3, a new cylinder block (4) is inserted from the lower end of the steel tower part (2), and is welded to the upper cylinder block to make the cylinder block (4). The tube body (5) to which the joint is connected is lifted, and thus the connection of the cylinder block and the lifting of the cylinder body are repeated to completely erect the cylinder body (5).
(Refer to FIG. 4) Next, using the erection ring (6) attached to the top of the tubular body (5), the frame (7) for erection of the steel tower member is assembled to this, and from the same frame (7) Lifting wire (8)
, The upper layer steel tower member (9) is lifted and spliced on the steel tower part (2) (see FIG. 5), and thereafter, the same operation as above is repeated, as shown in FIGS. 6 and 7. A steel tower-supporting chimney will be erected on.

果を有する。(Effects of the Invention) According to the method of the present invention, the low-rise steel tower section is erected by truck crane, and then the tubular body is hung from the top of the steel tower section to complete the hoisting of the entire tubular body. ,
Since the member for the upper layer tower is hoisted and erected using the hoisting ring attached to the top of the same cylinder, only the hoisting wire and winch that are commonly used in the erection work are used in addition to the truck crane. Therefore, it is possible to construct a high-rise tower-supporting chimney with a small truck crane without the use of special erection equipment such as an erector.In addition, when a mist-catcher is hung on the top of the barrel, the steel tower Since it can pass through a wide area on the lower side, it has the effect of facilitating installation.
