DISMANTLING METHOD FOR SMOKESTACKS
There is provided an aggregate stack demolishing scaffold apparatus capable of easily demolishing even an aggregate stack with safety at low cost, and a demolishing method using the apparatus. An aggregate stack demolishing scaffold apparatus 10 to be mounted to an upper part of an aggregate stack 130 including four smoke funnels 132 arranged adjacent to each other includes: an uneven scaffold including a one plate-shaped upper scaffold portion 14 that can be placed on an upper end of each smoke funnel 132, and lower scaffold portions 18 coupled to the upper scaffold portion 14 and located in lower positions in the smoke funnels 132 with the upper scaffold portion 14 being placed on the upper ends of the smoke funnels 132; and a chain block 28 capable of suspending and supporting the uneven scaffold from and on an inner wall of each smoke funnel 132, and adjusting a suspending height. With this configuration, the one plate-shaped upper scaffold portion 14 is located on the upper ends of the smoke funnels 132, and thus there is no possibility that a contact between scaffolds vertically moves the lower scaffold portions in the smoke funnels causing a worker to lose his balance, thereby improving safety.
