SHEAR REINFORCING BAR, REINFORCEMENT CONCRETE STRUCTURE AND CONSTRUCTING METHOD THEREFOR
PROBLEM TO BE SOLVED: To greatly improve workability by providing a shear reinforcing bar united with a reinforcing bar for buckling prevention representative of an intermediate belt reinforcing bar, and enabling the shear reinforcing bar to be inserted laterally.SOLUTION: There is provided a shear reinforcing bar 1 formed in a three-dimensional shape by bending a center part of a reinforcing bar by approximately 180 degrees into a substantially a U-shape 1a having one half part and the other half part substantially in parallel, and then bending an open end part 1c toward the side of a continuous end part 1b of the substantially U-shape 1a. Specifically, the side of a continuous end part 2b of the substantially U-shape and the side of the open end part 1c are bent in the same direction. Further, the shear reinforcing bar comprises a fixture 1d at the open end part 1c. Then an RC structure is constructed by arranging the shear reinforcing bar 1 laterally adjacently outside a main reinforcing bar 3 and also inserting the open end part 1c of the adjacently arranged shear reinforcing bar 1 inside the continuous end part 1b thereof into a connection state, and then casting concrete.SELECTED DRAWING: Figure 1
【課題】中間帯鉄筋を代替する座屈防止用鉄筋と一体化したせん断補強筋を提供して、せん断補強筋の横からの挿入を可能とし、施工性を大幅に向上する。【解決手段】鉄筋を中央部で略１８０度曲げ加工して一半部と他半部が略平行する略Ｕ字状１ａに形成し、その略Ｕ字状１ａの連続端部１ｂ側に対し開放端部１ｃを曲げ加工して三次元形状に形成したせん断補強筋１。具体的には、略Ｕ字状の連続端部２ｂ側と開放端部１ｃ側を同一方向に曲げ加工する。さらに、開放端部１ｃに定着具１ｄを備える。そして、せん断補強筋１を主鉄筋３の外側で横方向に隣接させて配置するとともに、その連続端部１ｂの内方に、隣接配置されるせん断補強筋１の開放端部１ｃを挿入して接続状態にして、コンクリートを打設してＲＣ構造物を構築する。【選択図】図１
