SYSTEM FOR CUTTING AND SEPARATING FLOOR SLAB AND METHOD FOR CUTTING AND SEPARATING CONCRETE FLOOR SLAB AND MAIN GIRDER
To efficiently cut and separate a concrete floor slab and a main girder by effectively utilizing a narrow working space under the existing floor block by utilizing an auxiliary device.SOLUTION: A floor slab cutting and separating system for cutting and separating a joint part between a concrete floor slab and a main girder of a bridge, comprises: a cutting device including a wire saw, a driven pulley around which the wire saw is wound, and a moving device which is provided with the driven pulley, forms a pair with the main girder interposed therebetween, and moves along the main girder below the concrete floor slab; an auxiliary device provided to assist the cutting and separating work of the joint part by the cutting device; and a rotational motion transmission mechanism to transmit the rotational motion of the driven pulley to the auxiliary device.SELECTED DRAWING: Figure 2
【課題】補助装置を利用して既設床版下の狭隘な作業空間を有効に活用し、効率よくコンクリート床版と主桁とを切断分離することである。【解決手段】橋梁のコンクリート床版と主桁との接合部を切断分離する床版切断分離システムであって、ワイヤーソー、該ワイヤーソーが掛回される従動プーリー、及び該従動プーリーが設けられるとともに前記主桁を挟んで対をなし、コンクリート床版の下方で前記主桁に沿って移動する移動装置を含む切断装置と、該切断装置による前記接合部の切断分離作業を補助する補助装置と、前記従動プーリーの回転運動を前記補助装置に伝達する回転運動伝達機構と、を備える。【選択図】図２
