CUTTING METHOD OF FLOOR SLAB, FLOOR SLAB EXCHANGE CONSTRUCTION METHOD AND SHEAR REINFORCEMENT STRUCTURE
To further reduce a construction traffic regulation time to be accompanied in floor slab renewal construction by detaching an existing floor slab and a main girder while opening traffic.SOLUTION: A cutting method of a floor slab for cutting and detaching a concrete floor slab and a main girder of a bridge at their junction comprises: a reinforcement step of providing a shear reinforcement structure adjacent to a cutting section located at the junction in a bridge axial direction; and a cutting surface formation step of forming a cutting surface approximately parallel to the main girder at the cutting section.SELECTED DRAWING: Figure 2
【課題】既設床版と主桁とを交通を開放しつつ分離し、床版更新工事時に伴う工事交通規制時間の更なる短縮化を図る。【解決手段】橋梁のコンクリート床版と主桁とを接合部で切断分離する、床版の切断方法であって、前記接合部に設定した切断区間と橋軸方向に隣接してせん断補強構造を設ける補強工程と、前記切断区間に前記主桁と略平行な切断面を形成する切断面形成工程と、を備えることを特徴とする。【選択図】図２
