CONNECTION STRUCTURE OF PRECAST CONCRETE BEAM END AND PRECAST CONCRETE BEAM COLUMN FRAME
PROBLEM TO BE SOLVED: To provide a connection structure of a precast concrete beam end, which has good workability, and a precast concrete beam column frame.SOLUTION: A connection structure 20 connects ends of a pair of precast concrete beams 21, 22 that butt against each other. The pair of precast concrete beams 21, 22 have thin concrete parts 23b, 24b, which protrude at lower side of the ends in butting direction, and lower end main reinforcements 27, 28, which extend in lengthwise direction in the thin concrete parts 23b, 24b, respectively. End faces of the thin concrete parts 23b, 24b are disposed so as to face each other. The connection structure comprises: an auxiliary reinforcement 31, which is disposed so as to stride the lower end main reinforcements 27, 28 of the pair of precast concrete beams 21, 22 above the thin concrete parts 23b, 24b along lower end main reinforcements 27, 28; and a concrete part, which is installed so as to embed the auxiliary reinforcement 31 between the pair of precast concrete beams 21, 22.SELECTED DRAWING: Figure 2
【課題】作業性が良いプレキャストコンクリート梁端部の接合構造及びプレキャストコンクリート梁柱架構を提供する。【解決手段】突き合わされた一対のプレキャストコンクリート梁２１、２２端部の接合構造２０であって、一対のプレキャストコンクリート梁２１、２２の各々は、端部下側が突き合わせ方向に突出する薄肉コンクリート部２３ｂ、２４ｂと、薄肉コンクリート部２３ｂ、２４ｂ内に長さ方向に延在する下端主筋２７、２８とを有し、前記薄肉コンクリート部２３ｂ、２４ｂの端面を互いに対向させて配設されており、薄肉コンクリート部２３ｂ、２４ｂの上方で、一対のプレキャストコンクリート梁２１、２２の各々の前記下端主筋２７、２８間を跨り、かつ、下端主筋２７、２８に沿って配設されている添筋３１と、一対のプレキャストコンクリート梁２１、２２間に、添筋３１を埋設するように打設されたコンクリート部と、を備える。【選択図】図２
