Abstract: PURPOSE:To remove a cornice being produced in the doorway of a building by installing a cornice shearing body ranging from a roof in an eaved manner free of tilting motion, and tilting this cornice shearing body upward by means of a cylinder. CONSTITUTION:A cornice shearing body 3 ranging from a roof 2b in an eaved manner is installed in the upper part of a doorway 2a of a snowshed 2 free of tilting motion, and an interval between this cornice shearing body 3 and the doorway 2a is pivotally connected by an expansion cylinder 7. Then, this cylinder 7 is expandedly operated, tilting the cornice shearing body 3 upward, and a cornice layer 9 on top of the cornice shearing body 3 is pushed up, thereby shearing a non-cornice layer 8 for separation. In addition, when a tilting value of the cornice shearing body 3 grows larger than same degree, the cornice layer 9 separated from the non-cornice layer 8 slides down and drops to the side of the doorway 2a from the cornice shearing body 3. Therefore, even in the case where the cornice is solidified by freezing, it is surely removable.
