FLOOR SLAB REPLACING METHOD
To provide a floor slab replacement method capable of opening traffic without carrying out reinforcement work even in the middle of the floor slab replacement work of an existing composite girder and minimizing a traffic blocking period.SOLUTION: In a floor slab replacing method for removing an existing floor slab 3a of an existing composite girder and sequentially replacing it with a new floor slab 3b, a temporary floor slab 5 having strength capable of being regarded as a rigid body against a force acting in a bridge axis direction is installed at a removal place of the existing floor slab 3a at least on a main girder 2, and an axial force is transmitted to the existing floor slab 3a before removal and the new floor slab 3b via the temporary floor slab 5 on the main girder 2.SELECTED DRAWING: Figure 4
【課題】既設合成桁の床版取替え工事の途中であっても、補強工事を行うことなく交通を開放でき、交通遮断期間を最小限にすることができる床版取替工法を提供する。【解決手段】既設合成桁の既設床版３ａを撤去して新設床版３ｂに順次取替える床版取替工法であって、少なくとも主桁２上において、橋軸方向に作用する力に対して剛体とみなすことができる強度を備えた仮設床版５を既設床版３ａの撤去箇所に設置し、主桁２上において、撤去前の既設床版３ａと新設床版３ｂとに仮設床版５を介して軸力を伝達させる。【選択図】図４
