FLOOR SLAB REMOVAL METHOD AND FLOOR SLAB REMOVAL DEVICE
To provide a floor slab removal method and a floor slab removal device which make it possible to easily install a device for removing a floor slab and to easily perform a removal operation of the floor slab.SOLUTION: A floor slab removal method for removing a floor slab 10A put on a stringer from the stringer, comprises the steps of: drilling a hole 30 extending in a vertical direction D2 on an upper surface 10b of the floor slab 10A; inserting a rod-shaped anchor 20 into the hole 30 from above in the vertical direction D2; hooking the anchor 20 in the hole 30 by expanding the diameter of the anchor 20 inserted inside the hole 30 with respect to the hole 30; and pulling the anchor 20 upward in the vertical direction D2 and peeling the floor slab 10A from the stringer.SELECTED DRAWING: Figure 5
【課題】床版を撤去する装置の設置を容易に行うことができると共に床版の撤去作業を容易に行うことができる床版撤去方法及び床版撤去装置を提供する。【解決手段】一実施形態に係る床版撤去方法は、桁材に載せられた床版１０Ａを桁材から撤去する床版撤去方法であって、床版１０Ａの上面１０ｂに、鉛直方向Ｄ２に延びる穴３０を削孔する工程と、穴３０に鉛直方向Ｄ２上側から棒状のアンカー２０を挿入する工程と、穴３０の内部に挿入されたアンカー２０を穴３０に対して拡径することにより、穴３０にアンカー２０を引っ掛ける工程と、アンカー２０を鉛直方向Ｄ２上側に引っ張り上げて桁材から床版１０Ａを引き剥がす工程と、を備える。【選択図】図５
