Title:
FLOOR SLAB STRUCTURE AND BONDING METHOD
Document Type and Number:
Japanese Patent JP2023097877
Kind Code:
A
Abstract:
To provide a floor slab structure and a bonding method that are capable of obtaining necessary compressive force in a bridge axis direction.SOLUTION: A floor slab structure 1 according to one embodiment comprises: a support member 3 that extends in a bridge axial right-angled direction D2 orthogonal to a bridge axis direction D1; a plurality of precast concrete floor slabs 5 that are aligned along the bridge axis direction D1; a filling material 30 that is filled between the pair of precast concrete floor slabs 5; and a tension member 20 that is inserted, along the bridge axis direction D1, through the plurality of precast concrete floor slabs 5. Prestress by a post tension scheme is introduced, by the tension member 20, to the plurality of precast concrete floor slabs 5 continuing in the bridge axis direction D1. The floor slab structure 1 further comprises a fixing unit that is positioned outside the plurality of precast concrete floor slabs 5, in the bridge axial direction D1, to which the prestress is introduced, and fixes the tension member 20 to the precast concrete floor slab 5.SELECTED DRAWING: Figure 3
