REINFORCING-BAR ARRANGEMENT STRUCTURE FOR REINFORCEMENT CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a reinforcing-bar arrangement structure capable of constructing a reinforcing concrete structure having excellent seismic performance.SOLUTION: A reinforcing-bar arrangement structure for a reinforcement concrete structure comprises: a main reinforcement body arranged so that M (M≥3) first main bars extending in the axial direction form M angular shapes in an imaginary plane orthogonal to the axial direction; a plurality of shear reinforcement-bar disposed between adjacent first main reinforcement-bars and connected to each other; and a plurality of second main reinforcing-bars extending in the axial direction within the M prismatic space surrounded by the M first main reinforcing-bars and the plurality of shear reinforcement-bar and attached to the plurality of shear reinforcing-bar. Each of the shear reinforcing-bar includes a pair of engagement members fixed to each of the adjacent first main reinforcement-bar, a hollow tube disposed between the pair of engagement members, and a tightening member which penetrates the inside of the hollow pipe and both ends of which are locked to the engagement members, respectively, to provide a tensile force. The hollow pipe is sandwiched between the adjacent first main reinforcement-bars to integrate them by tensile force of the engagement members.SELECTED DRAWING: Figure 1
【課題】優れた耐震性能を有する鉄筋コンクリート構造物を構築することを可能とする配筋構造を提供する。【解決手段】軸方向に延設された第１主筋がＭ本（Ｍ≧３）、軸方向と直交する仮想面内でＭ角形を形成するように、配置された主筋体と、互いに隣り合う第１主筋の間に配置されて相互に連結する複数のせん断補強筋と、Ｍ本の第１主筋と複数のせん断補強筋により取り囲まれて形成されたＭ角柱状の空間内で軸方向に延設されるとともに複数のせん断補強筋に取り付けられる複数の第２主筋と、を備え、各せん断補強筋は、隣り合う第１主筋の各々に固定される一対の係止部材と、一対の係止部材の間に配置される中空管と、中空管の内部を貫通しながら両端部がそれぞれ係止部材に係止されて緊張力を与える緊締部材とを有し、緊締部材の緊張力によって隣り合う第１主筋で中空管を挟んで一体化させる。【選択図】図１
