FLOOR SLAB CUTTING DEVICE IN FLOOR SLAB CUTTING WORK AND ARRANGEMENT STRUCTURE OF TEMPORARY ENCLOSURE
To prevent infiltration of rainwater to the lower surface side of a concrete floor slab and to facilitate horizontal cutting of a joint boundary surface between a bridge girder and the concrete floor slab.SOLUTION: A device body of a floor slab cutting device CD for cutting a joint boundary surface J between a concrete floor slab 3 laid on a bridge girder 2 and constituting a road surface of a bridge 1 and the bridge girder 2 by a waterless wire saw 5 is arranged below the concrete floor slab 3; an all-weather type temporary enclosure 20 which covers the concrete floor slab 3 of a part where the floor slab cutting device CD is arranged below from above is arranged on the upper surface of the concrete floor slab 3; a through-hole penetrating the concrete floor slab 3 for passing the wire saw 5 in the thickness direction is formed in the concrete floor slab 3 at the part where the floor slab cutting device CD is arranged below.SELECTED DRAWING: Figure 11
【課題】コンクリート床版の下面側への雨水の浸入を防ぎ、橋桁とコンクリート床版との接合境界面を水平切断しやすくする。【解決手段】橋桁２上に敷設されて橋梁１の路面を構成するコンクリート床版３と橋桁２との接合境界面Jを無水式のワイヤーソー５によって切断する床版切断装置ＣＤの装置本体が、コンクリート床版３の下方に配置されており、床版切断装置ＣＤが下方に配置された部分のコンクリート床版３を上方から覆う全天候型の仮囲い２０が、コンクリート床版３の上面に配置されており、床版切断装置ＣＤが下方に配置された部分のコンクリート床版３には、ワイヤーソー５を通すためのコンクリート床版３を厚み方向に貫通する貫通孔が形成されている。【選択図】図１１
