REINFORCEMENT CONNECTION STRUCTURE BETWEEN PRECAST MEMBERS, HALF PRECAST CONCRETE SLAB COMPRISING THE REINFORCEMENT CONNECTION STRUCTURE, AND HALF PRECAST CONCRETE WALL COMPRISING THE REINFORCEMENT CONNECTION STRUCTURE
To achieve both strengths at a joining place and improvement in constructibility and workability in a connecting structure for joining a plurality of adjacent precast members to each other by using reinforcements.SOLUTION: In a connecting structure for joining a plurality of adjacent precast members, a first precast member and a second precast member adjacent to each other are respectively embedded with a reinforcement group for joining; an end part of the reinforcement group for joining protrudes into a cast-in-place concrete part above an upper surface of the precast member in the vicinity of a joining end part of the first precast member and the second precast member; inside the cast-in-place concrete part, a connecting reinforcement group is provided so as to straddle the joining end part between the first precast member and the second precast member, and the end part of the reinforcement group for joining projected into the cast-in-place concrete part and both end parts of the connecting reinforcement group has a shape folded back in a hook shape so as to face each other.SELECTED DRAWING: Figure 1
【課題】複数の隣接するプレキャスト部材同士を鉄筋を用いて接合させる連結構造において、接合箇所での強度と、施工性や作業性の向上を両立させる。【解決手段】互いに隣接する第１のプレキャスト部材と第２のプレキャスト部材とには、それぞれ接合用鉄筋群が埋設され、接合用鉄筋群の端部は、第１のプレキャスト部材と第２のプレキャスト部材との接合端部近傍においてプレキャスト部材の上面より上方の現場打ちコンクリート部中に突出し、現場打ちコンクリート部の内部には、第１のプレキャスト部材と第２のプレキャスト部材との接合端部を跨ぐように連結鉄筋群が設けられ、現場打ちコンクリート部中に突出した接合用鉄筋群の端部と、連結鉄筋群の両端部は互いに向き合うようにフック状に折り返された形状を有する。【選択図】図１
