PROBLEM TO BE SOLVED: To provide a comparatively compact and lightweight construction apparatus and a construction method used in the construction of a floor slab as well as a bridge girder. SOLUTION: This construction apparatus for bridge has a plurality of hinges 16 having one horizontal shaft crossing the direction of bridge axis orthogonally as a turning shaft in common, a suspension frame 12 being turnable in the direction of bridge axis around the turning shaft of the hinges 16, a supporting frame 14 for supporting the suspension frame 12 turnably, a fixing device 22 for transmitting the force applied on the supporting frame 14 to an existing bridge girder 2 or an existing floor slab 5 constructed on the constructed bridge girder, a driving device 18 for turning the suspension frame 12 in the direction of bridge axis around the turning shaft while controlling its turning speed, an elevating apparatus 20 for elevating and lowering a bridge girder block 1 or the floor slab 4, and a swivel device 21 for swiveling the floor slab 4 lifted by the elevating device 20 in the predetermined direction.
