Zusammenfassung:	To provide a floor slab removal method that efficiently removes a floor slab from a girder.SOLUTION: A floor slab removal method of the present invention bridges a beam material 20 between an adjacent block 2n and a girder 4 from which a block 2a has already been removed so that a block 2r to be removed straddles the longitudinal direction of a bridge 1. A drive unit 10 supported by the beam material 20 is connected to the block 2r to be removed. The drive unit 10 is then driven to separate the block 2r to be removed from the girder 4.SELECTED DRAWING: Figure 2 【課題】床版を桁から効率よく撤去する床版撤去方法を提供する。【解決手段】床版撤去方法は、撤去対象ブロック２ｒを橋梁１の長手方向に跨ぐように、隣接ブロック２ｎと、ブロック２ａが既に撤去された桁４と、の間に梁材２０を架け渡し、梁材２０に支持された駆動部１０を撤去対象ブロック２ｒに連結し、駆動部１０を駆動して撤去対象ブロック２ｒを桁４から剥離する。【選択図】図２
