PRECAST FLOOR SLAB JOINT STRUCTURE
To provide a precast floor slab joint structure capable of securing a reinforcing bar covering even when an anchoring part is provided at the end of the reinforcing bar extending in a bridge axial direction in a precast floor slab using an end band joint.SOLUTION: Fixing plates 21, 22 arranged at the end of a reinforcing joint extending in a bridge axis direction (± X direction) from a precast floor slab 1 in a joint part for joining the precast floor slabs 1 to each other is arranged in a direction orthogonal to the bridge axis direction, and cover thicknesses d1 and d2 of reinforcing bars are secured by having bulges on the plane sides of other slab surfaces S2, S1 from contact surfaces S11, S12 of the fixing plates 21, 22 on the side of the close slab surfaces S1, S2, which are parallel to the plane of the close slab surfaces S1, S2 between the upper and lower slab surfaces S1, S2 of the precast floor slab 1.SELECTED DRAWING: Figure 3
【課題】エンドバンド継手を用いたプレキャスト床版における橋軸方向に延びる鉄筋の端部に定着部を設ける場合であっても鉄筋かぶりを確保することができるプレキャスト床版継手構造を提供する。【解決手段】プレキャスト床版１を互いに接合する接合部においてプレキャスト床版１から橋軸方向（±Ｘ方向）に延びる鉄筋継手の端部に配置される定着版２１，２２は、橋軸方向に直交する方向であって、プレキャスト床版１の上下の版面Ｓ１，Ｓ２のうちの近い版面Ｓ１，Ｓ２の平面に平行であり該近い版面Ｓ１，Ｓ２側における定着版２１，２２の接面Ｓ１１，Ｓ１２から、他の版面Ｓ２，Ｓ１の平面側に膨らみを持たせ、鉄筋のかぶり厚さｄ１，ｄ２を確保する。【選択図】図３
