CONNECTION STRUCTURE AND CONNECTION METHOD OF PRECAST CONCRETE MEMBER
To eliminate a need for scaffolding for inserting PC steel and introducing prestress, and to prevent the lengthening of PC steel.SOLUTION: A connection structure 104 of a precast concrete member has an anchor plate 3a, being attached to one end of a PC steel bar 2, embedded in a precast concrete member 103a, and an anchor plate 3b, being attached to the other end, embedded in a tensile force transmission part 113, which is continuously and integrally provided in a precast concrete member 103b. The precast concrete members 103a, 103b are attracted to each other and connected by the tensile force of the PC steel bar 2 via a bearing pressure generated on the anchor plates 3a, 3b. The tensile force transmission part 113 is constructed of post-cast concrete in a notch 114 formed in the precast concrete member 103b so as to be adjacent to the precast concrete member 103a.SELECTED DRAWING: Figure 2
【課題】ＰＣ鋼材の挿入作業やプレストレス導入のための作業足場を不要にするとともに、ＰＣ鋼材の長尺化を防止する。【解決手段】本発明に係るプレキャストコンクリート部材の連結構造１０４は、ＰＣ鋼棒２の一方の端部に取り付けられた定着板３ａをプレキャストコンクリート部材１０３ａに、他方の端部に取り付けられた定着板３ｂを、プレキャストコンクリート部材１０３ｂと連続一体に設けられた引張力伝達部１１３にそれぞれ埋設してあり、定着板３ａ，３ｂにおける支圧を介したＰＣ鋼棒２の引張力でプレキャストコンクリート部材１０３ａ，１０３ｂを互いに引き寄せて連結してある。引張力伝達部１１３は、プレキャストコンクリート部材１０３ａに隣り合うようにプレキャストコンクリート部材１０３ｂに形成された切り欠き１１４に後打ちコンクリートで構築してある。【選択図】 図２
