<p>A building demolishing method that does not require a large-sized machine to construct a shield and always secures a scaffolding necessary for demolishing a building, comprising the steps of erecting guide columns (2) disposed at predetermined intervals around the side of a building (a) to be demolished, assembling a shield (1) vertically slidable as guided by the guide columns (2) to surround the lateral periphery of the building (a) at the level of the ground or the lowermost story of the building (a), and storing demolishing machines (8-10) in the shield (1). And, guide column members (2a) are upwardly extended and the shield (1) is raised as guided by the guide column members (2) to surround the lateral periphery of the uppermost story of the building (a). And, demolishing machines (8-10) demolish the building (a), and each time the demolishment of one story is completed, the shield (1) storing the demolishing machines (8-10) is lowered as guided along the guide column members (2) while shortening the guide column members (2), such operation being repeated to demolish the building (a).</p> |
