<P>PROBLEM TO BE SOLVED: To provide a precast floor slab and its erection method capable of lowering a construction cost. <P>SOLUTION: In the precast floor slab including an upper joint reinforcing bar and a lower joint reinforcing bar, an upper floor slab end face 11 at a bridge axial direction end part of a floor slab body at the proximal end part on an overhung side in the upper joint reinforcing bar 5a is provided so as to be displaced toward the center part in the bridge axial direction more than a lower floor slab end face 12 at the bridge axial direction end part of the floor slab body at the proximal end part on the overhung side in the lower joint reinforcing bar 5b. A step part continued in a bridge axis perpendicular direction is provided between the upper floor slab end face 11 and the lower floor slab end face 12, and by the proximal end parts of many upper joint reinforcing bars 5a and the step part in the bridge axial direction on the precast floor slab 2, a temporary placing storage groove 15 for reinforcing bars continued in the bridge axis perpendicular direction is formed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
