METHOD FOR REMOVING FLOOR SLAB OF COMPOSITE GIRDER BRIDGE AND REINFORCEMENT MEMBER USED FOR THE SAME
To provide a method for removing a composite girder bridge floor slab and a reinforcing member used for the method by which a concrete of a floor slab haunch part is removed in advance with a water jet while a road is being served and reinforcing is carried out successively, whereby by a working period after closure is drastically reduced.SOLUTION: A method for removing a floor slab of a composite girder bridge according to the present invention includes a step of removing a predetermined section of concrete of a floor slab haunch part from the side of the floor slab haunch part with a water jet while maintaining the upper surface of the floor slab; a step of installing a reinforcing member in a section from which concrete has been removed; a step of removing a floor slab by removing a reinforcing member after stopping passage on the floor slab, and a step of removing a predetermined section of the concrete and a step of installing a reinforcing member are repeated while changing sections, and the concrete of the floor slab haunch part in the section where the floor slab is removed is removed.SELECTED DRAWING: Figure 5
【課題】道路を供用しながら予め床版ハンチ部のコンクリートをウォータージェットで除去し、順次補強することで、通行止め後の作業期間を大幅に短縮する合成桁橋床版の撤去方法及びこれに使用される補強部材を提供する。【解決手段】本発明による合成桁橋の床版の撤去方法は、床版の上面を維持したまま床版ハンチ部の側方から床版ハンチ部のコンクリートをウォータージェットで所定の区間除去する段階と、コンクリートを除去した区間に補強部材を設置する段階と、床版上の通行を止めた後、補強部材を撤去して床版を撤去する段階とを含み、前記コンクリートを所定の区間除去する段階と補強部材を設置する段階とを区間を変えながら繰り返し、床版を撤去する区間の床版ハンチ部のコンクリートを除去することを特徴とする。【選択図】図５
