Method for toppling tower building in which base is used

Abstract

To provide a method of toppling a tower structure more safely, simply and quickly than in the conventional manner. In a method of toppling a tower structure that is fixedly supported on a baseto demolish the tower structure, the method includes a base dividing step of dividing the baseinto an upper baseand a lower base, by cutting the basein a substantially horizontal direction, an upper base dividing step of dividing the upper baseinto a support base portionand a separated base portionby cutting the upper base, in a longitudinal direction, from above to a substantially horizontal surface, a removing step of removing the separated base portion, and a toppling step of toppling the tower structuretogether with the support base portionusing, as a tumble axis, a lower edge of a longitudinally cut surfaceof the support base portion, in which the tumble axisis located on a toppling direction side of the tower structure with respect to a center of gravity C. Thus, since the tumble axisof the robust base serves as a tumble fulcrum by itself, there is no possibility that breakage of the base is caused even by the concentration of a buckling load, and the tower structure can be toppled in an intended direction.
