Scaffolding equipment for aggregate smokestack dismantling and dismantling method for aggregate smokestack using same equipment

Abstract

The purpose of the present invention is to provide scaffolding equipment for smokestack dismantling and a dismantling method using the equipment capable of easily dismantling even aggregate smokestacks at a low cost while maintaining safety. Scaffolding equipment for smokestack dismantling (10), that is mounted to the top of an aggregate smokestack (13) for which four chimneys (132) are disposed mutually adjacent, comprises: an uneven scaffold having an upper scaffold portion (14) that is a single plate capable of being mounted on the upper end of the chimneys (132) and lower scaffold portions (18) each coupled to the upper scaffold portion (14) and, with the upper scaffold portion (14) mounted as described above, located at a lower position in the chimneys (132); and chain blocks (28) that suspend and support the uneven scaffold inside of the wall of the chimneys (132) and for which the suspension height is adjustable. With this configuration, because the scaffold at the top end of the chimneys (132) is the single-plate upper scaffold portion (14), there is no danger of the lower scaffold portion in each chimney moving vertically due to contact between scaffolds nor of workers losing their balance, and work safety is improved.

Description

technical field [0001] The present invention relates to a scaffolding device for dismantling a collective chimney for dismantling a collective chimney formed by arranging a plurality of chimneys in one place from the top thereof, and a method for removing a collective chimney using the same. Background technique [0002] In the past, when dismantling a very high-rise chimney, a temporary scaffold was built from the ground to the top of the chimney by using a crane or a tower crane standing on the ground, using steel pipes / plates, etc. break up) or remove the chimney from its upper end by gas fusing the metal chimney. However, construction and removal of temporary scaffolds for such high-rise chimneys require a lot of labor. In addition, since it is necessary to construct the entire temporary scaffold firmly, the construction period of the entire chimney dismantling work becomes longer, and thus the construction cost increases. In addition, a crane is also required to remov...

Problems solved by technology

However, in this case, the upper floor parts 102 placed on the upper ends of the adjacent chimneys contact each other, and the mutual scaffolding frames 108 move up and down due to the contact, which may cause the operator who works at a high altitude to lose his balance, which is very dangerous.

[0009] In addition, if the area of ​​the upper floor portion 102 is reduced in order to avoid contact between the upper floor portions 102, it becomes difficult to ensure sufficient scaffolding for the operator who works at a high altitude to remove the outer column 134 of the iron tower. still dangerous
