JOINT STRUCTURE OF PRECAST CONCRETE FLOOR SLAB
To provide a joint structure of a precast concrete floor slab in which the length of a joint part can be reduced than that of a lap joint structure, a floor slab thickness can be thinner than that of a loop reinforcement joint structure, and also the burden of bar arrangement work in the field can be reduced.SOLUTION: An upper stage slip preventing member 16 is configured to have an upper stage locking part 16B having an upper stage inner surface 16B1 on the opposite side from the direction in which the upper stage joint reinforcing bar 12 projects. A lower stage slip preventing member 18 is configured to have a lower stage locking part 18B having a lower stage inner surface 18B1 on the opposite side from the direction in which the lower stage joint reinforcing bar 14 projects. An upper stage orthogonal reinforcing bar 20 is arranged between the upper stage locking parts 16B at a space from the upper stage locking part 16B, and a lower stage orthogonal reinforcing bar is arranged between the lower stage locking parts 18B at a space from the lower stage locking part 18B.SELECTED DRAWING: Figure 3
【課題】重ね継ぎ手構造よりも接合部の長さを短くでき、かつ、ループ鉄筋継ぎ手構造よりも床版厚を薄くでき、さらに、現場での配筋作業の負担も少なくすることができるプレキャストコンクリート床版の継ぎ手構造を提供する。【解決手段】上段ずれ止め部材１６は、上段内面１６Ｂ１を上段継ぎ手鉄筋１２の突出する方向とは逆の側に有する上段係止部１６Ｂを有してなり、下段ずれ止め部材１８は、下段内面１８Ｂ１を下段継ぎ手鉄筋１４の突出する方向とは逆の側に有する下段係止部１８Ｂを有してなり、上段直交鉄筋２０が上段係止部１６Ｂ同士の間に上段係止部１６Ｂから間隔を空けて配置されており、下段直交鉄筋が下段係止部１８Ｂ同士の間に下段係止部１８Ｂから間隔を空けて配置されている。【選択図】図３
