RC MEMBER USING MAIN REINFORCEMENT SURROUNDING REINFORCEMENT BAR
To provide an RC member using a main reinforcement surrounding reinforcement bar enhancing binding force of the main reinforcement and concrete and restricting an adhesion splitting failure of the concrete surrounding the main reinforcement.SOLUTION: In an RC member 1 which is a beam member 10 or a column member having a plurality of main reinforcements 13 extending in a long direction and concrete 15 having the main reinforcement inside, the plurality of main reinforcements are aligned and arranged in respective vicinities of two sides facing each other in a rectangular cross section of the RC member at least vertical to the main reinforcement, and comprises a first side 13a provided in the vicinity of one row of the main reinforcement so as to be along the one row of the main reinforcement at least aligned in the most vicinity of one side and a second side 13b present in the concrete facing the first side and apart from the main reinforcement for a prescribed distance, and a main reinforcement surrounding reinforcement bar arranged so as to enclose at least one row of the main reinforcement and the concrete adjacent to one row of the main reinforcement is provided in a prescribed range of an axial direction of the main reinforcement from the vicinity of a material end of the RC member.SELECTED DRAWING: Figure 1
【課題】主筋とコンクリートとの拘束力を高めて主筋周辺のコンクリートの付着割裂破壊を抑制する主筋周囲補強筋を用いたＲＣ部材を提供する。【解決手段】長手方向に延在する複数の主筋１３と主筋を内在させるコンクリート１５とを有する梁部材１０または柱部材であるＲＣ部材１において、複数の主筋は少なくとも主筋に垂直なＲＣ部材の矩形断面内で対向する２辺のそれぞれの近傍に整列して配置され、少なくとも一方の辺の最近傍に整列された１列の主筋に沿うように１列の主筋の近傍に設けられる第１辺１３ａと、第１辺に対向し主筋から所定の距離離隔したコンクリート中に位置する第２辺１３ｂとを含み、少なくとも１列の主筋と１列の主筋に隣接するコンクリートとを囲むように配置される主筋周囲補強筋がＲＣ部材の材端部近傍から主筋の軸方向の所定の範囲に設けられる。【選択図】図１
