PROBLEM TO BE SOLVED: To efficiently dismantle a structure.SOLUTION: Two cuts are formed in a slab 32 on an H-steel 30A as part of a beam 30, and impact is given to a removal part 29 between the two cuts by a hammer or the like to remove the removal part 29 so that the H-steel 30A is exposed. Then, the H-steel 30A exposed from an exposure site 27 is cut. Thus, as compared with the case that a breaker or the like is used for breaking off and removing the removal part 29, the removal part 29 is easily removed so that the H-steel 30A can be exposed, and dust and noises are suppressed. This results in more efficient dismantling work for a building 10 to be dismantled. |
