PRECAST FLOOR SLAB JOINT STRUCTURE
To provide a precast floor slab joint structure which can reduce man-hours at a construction site and prevents a floor slab thickness from being unnecessarily increased.SOLUTION: A precast floor slab joint structure comprises: an upper joint reinforcement 22 and a lower joint reinforcement 23 which are arranged with a distance from each other in a vertical direction and extended from an edge face of a floor slab body 21 in a bridge axial direction; and a joint member 24 with an upper side and a lower side thereof fixed to the upper joint reinforcement 22 and the lower joint reinforcement 23 respectively. Because the joint member 24 enables bearing force of a filling material 20a to be utilized and can be made of a material different from the upper and lower joint reinforcement 22 and 23, a vertical distance between the upper and lower joint reinforcement 22 and 23 is not subject to the joint member 24 and thereby preventing a floor slab thickness from being unnecessarily increased unlike in a case of a conventional loop joint where a loop section causes the floor slab thickness to be increased.SELECTED DRAWING: Figure 3
【課題】施工現場での作業工数を低減することができるとともに、床版厚を無用に増大させることのないプレキャスト床版の接合構造を提供する。【解決手段】互いに上下方向に間隔をおいて配置された上側継手鉄筋２２及び下側継手鉄筋２３をそれぞれ床版本体２１の橋軸方向端面から延出するように設けるとともに、各継手鉄筋２２，２３には上端側及び下端側をそれぞれ上側継手鉄筋２２及び下側継手鉄筋２３に固定された継手部材２４を設けたので、継手部材２４によって間詰め材２０ａからの支圧力を得ることができるとともに、継手部材２４を各継手鉄筋２２，２３とは別部品から形成することができるので、上側継手鉄筋２２及び下側継手鉄筋２３の上下方向の間隔が継手部材２４によって制約を受けることがない。これにより、従来のループ継手を用いる場合のように床版厚がループ部分によって必要以上に大きくなることがない。【選択図】図３
