FLOOR SLAB CUTTER AND FLOOR SLAB CUTTING METHOD
To provide a floor slab cutter using a wire saw which extends continuously in a direction along a joint boundary surface between a bridge girder and a concrete slab and in width and thickness directions of the concrete slab, which is capable of prohibiting a cutting operation in the direction along the joint interface between the bridge girder and the concrete slab if necessary.SOLUTION: A floor slab cutter 20 includes: a wire saw 23 that extends continuously in the direction along the joint boundary surface between a bridge girder 2 and a concrete slab 3 and in the width and thickness directions of the concrete slab 3; and multiple pulleys for guiding and driving the wire saw 23 in a traveling direction along its extension route. In the vicinity of a cutting start part in the direction along a joint boundary C1 between the bridge girder 2 and the concrete slab 3, a fixed pulley 61 is arranged which prohibits the cutting operation in the direction along the joint boundary surface C1 between the bridge girder 2 and the concrete slab 3 by the drive of the wire saw 23 while guiding the wire saw 23 in the traveling direction.SELECTED DRAWING: Figure 1
【課題】橋桁とコンクリート床版の接合境界面に沿う方向とコンクリート床版の幅方向及び厚み方向に連続して延設されるワイヤーソーを用いた床版切断装置において、必要に応じて、橋桁とコンクリート床版の接合境界面に沿う方向の切断動作を禁止することを可能とする。【解決手段】橋桁２とコンクリート床版３との接合境界面に沿う方向とコンクリート床版３の幅方向及び厚み方向に連続して延設されるワイヤーソー２３と、そのワイヤーソー２３をその延設経路に沿った走行方向に案内するとともに走行駆動させるための複数のプーリと、を備えた床版切断装置２０において、橋桁２とコンクリート床版３の接合境界面Ｃ１に沿う方向の切断開始部分の近傍に、ワイヤーソー２３を走行方向に案内しながら、ワイヤーソー２３の駆動による橋桁２とコンクリート床版３の接合境界面Ｃ１に沿う方向の切断動作を禁止する固定プーリ６１を配置した。【選択図】図１
