にコンクリートを打設し一体とする構造において
、前記ハーフＰＣ梁の梁筋のうち長手方向に移動
自在に配筋された上端筋を、直線状の杆状体かつ
柱と梁の接合部内に埋設するに充分なる長さに形
成し、前記上端筋の先端部に同先端部を周方向に
拡張させた拡張定着部を同軸的に設け、前記鉄筋
コンクリート柱に前記ハーフＰＣ梁の梁筋を配筋

を打設し、柱と梁の接合部を一体としたことを特
徴とする柱と梁の接合構造。 In a structure in which concrete is cast at the joint between a reinforced concrete column and a half-PC beam to form an integral structure, the upper end reinforcement, which is arranged so as to be freely movable in the longitudinal direction, of the beam reinforcement of the half-PC beam is formed into a linear rod-like structure. The reinforced concrete column is formed to have a length sufficient to be buried in the body and the joint between the column and the beam, and is coaxially provided at the tip of the upper end reinforcement with an expanded anchoring section that expands the tip in the circumferential direction, and is attached to the reinforced concrete column. A column-to-beam joint structure characterized in that the beam reinforcement of the half-PC beam is arranged, concrete is poured so as to enclose these reinforcements, and the joint portion of the column and beam is integrated.
