METHOD FOR CUTTING EXISTING CONCRETE FLOOR SLAB
PROBLEM TO BE SOLVED: To provide a method for cutting an existing concrete floor slab, which enables a part of the existing concrete floor slab near a top surface of an upper flange of an existing main girder to be concurrently cut almost in parallel with the top surface of the upper flange of the existing main girder by a wire saw, in a plurality of locations positionally different from one another in a longitudinal direction of the existing main girder.SOLUTION: In a method for cutting an existing concrete floor slab, a part of an existing concrete floor slab 102 near a top surface of an upper flange 104A of an existing main girder 104 is cut by an endless wire saw 30 in a direction almost parallel to the top surface of the upper flange 104A of the existing main girder 104. Cutting performed by using the wire saw 30 wholly progresses in a direction almost orthogonal to a longitudinal direction of the existing main girder 104.SELECTED DRAWING: Figure 1
【課題】既設主桁の上フランジの上面近傍の既設コンクリート床版の部位を該既設主桁の上フランジの上面と略平行にワイヤーソーで切断するにあたり、前記切断を、既設主桁の長手方向に位置の異なる複数の箇所で同時に行うことができる既設コンクリート床版の切断方法を提供する。【解決手段】既設主桁１０４の上フランジ１０４Ａの上面近傍の既設コンクリート床版１０２の部位を、前記既設主桁１０４の前記上フランジ１０４Ａの上面と略平行な方向に無端状のワイヤーソー３０で切断する既設コンクリート床版の切断方法であって、前記ワイヤーソー３０による切断が、前記既設主桁１０４の長手方向と略直交する方向に全体として進行する。【選択図】図１
