PROBLEM TO BE SOLVED: To provide a temporary construction bridge and a floor slab replacement method to reduce the amount of time a road needs to be closed to traffic in order to perform floor slab replacement work.SOLUTION: A temporary construction bridge 1 comprises a first unit 100, a second unit 200 and a third unit 300, which form a temporary road TR above a road R undergoing floor slab FS replacement. When a temporary construction bridge is installed, there is no necessity to close the road to traffic even when performing floor slab replacement work. The first unit and the like comprise a first temporary road part 110A and the like which form the temporary road TR, and first connection parts 120A, 130A and the like which can be mutually detached and connected. Through changing the order in which the first unit and the like are connected by the first connection parts and the like, each of the first temporary road and the like forms the temporary road and a sloping road SR for connecting the temporary road and the road. The temporary construction bridge is moved by changing the order in which the first unit and the like are connected in accordance with the change in a floor slab replacement position. The amount of time the road needs to be closed to traffic can be reduced by moving the temporary construction bridge in accordance with the change in the floor slab replacement position.SELECTED DRAWING: Figure 6 【課題】床版の交換作業に伴う道路の通行止めの時間を短縮する仮設組立橋と床版交換方法を提供する。【解決手段】仮設組立橋１は、床版ＦＳが交換される道路Ｒの上方に仮設道路ＴＲを形成する第１ユニット１００、第２ユニット２００及び第３ユニット３００を備え、仮設組立橋の設置時は、床版の交換作業時も通行止めの必要が無い。第１ユニット等は、仮設道路ＴＲを形成する第１仮設道路部１１０Ａ等と、互いに着脱自在に連結可能な第１連結部１２０Ａ，１３０Ａ等とをそれぞれ有する。第１連結部等により第１ユニット等が連結される順序を変えて、第１仮設道路部等のそれぞれは仮設道路及び道路と仮設道路とを連結する坂路ＳＲを形成する。床版の交換位置の変更に伴って、第１ユニット等が連結される順序を変えつつ仮設組立橋を移動させ、床版の交換位置の変更に伴う仮設組立橋の移動のための通行止めの時間を短縮できる。【選択図】図６
