JOINT STRUCTURE OF PRECAST CONCRETE MEMBERS
To be able to reduce: the labor and time required for construction, the distance between the joint end faces, and the cost; and to also prevent the precast concrete members from twisting even when the number of joint reinforcement bars is small.SOLUTION: A joint structure of precast concrete members comprises: a joint reinforcement bar 10 having a widened part 10a at the tip, a mechanical anchorage 10A projecting the widened part 10a side from a joint end face 1a of a composite floor slab 1A, 1B; filling concrete 4 filled in a filling area 20 between the joint end faces 1a of the composite floor slab 1A, 1B; and a joint reinforcement 3, having a widened part 3a at both ends, arranged in the filling area 20 in the axial direction in parallel with the axial direction of the joint reinforcement bar 10. The mechanical anchorages 10A are arranged on a coaxial line with each other. The joint reinforcements 3 are provided between the mechanical anchorages 10A in the width direction to provide a joint structure of precast concrete members.SELECTED DRAWING: Figure 1
【課題】施工にかかる手間や時間を低減でき、接合端面同士の間の間隔を小さくすることが可能となり、コストの低減を図ることができるうえ、継手鉄筋の本数が少ない場合でもプレキャストコンクリート部材同士のねじれを防ぐことができる。【解決手段】先端部に拡幅部１０ａを備え、合成床版１Ａ、１Ｂの接合端面１ａから拡幅部１０ａ側を突出した機械式定着部１０Ａを有する継手鉄筋１０と、合成床版１Ａ、１Ｂの接合端面１ａ同士の間の間詰め領域２０に充填された間詰めコンクリート４と、両端に拡幅部３ａを有し、間詰め領域２０において軸方向を継手鉄筋１０の軸方向と平行に配置された接合鉄筋３と、を備え、機械式定着部１０Ａ同士は同軸線上に配置され、接合鉄筋３は幅方向で機械式定着部１０Ａ同士の間に配置された構成のプレキャストコンクリート部材の継手構造を提供する。【選択図】図１
