SHEAR REINFORCING BAR
To provide a shear reinforcing bar that greatly improves the connection strength between the main rebars or distributing bars by increasing adhesion of shear reinforcing bars and concrete.SOLUTION: It includes a steel bar 1 and a divided steel bar 2 obtained by dividing the steel bar with the plane parallel to the longer direction. The divided steel bar is fixed to at least one end of the steel bar via the division surface so as to be engaged with the main bar or the distribution bar, the width of the dividing plane is larger than the diameter of the steel bar, the divided steel bar is in the shape of a halved steel bar, and the steel bar and the divided steel bar are fixed by friction pressure welding.SELECTED DRAWING: Figure 1
【課題】せん断補強鉄筋とコンクリートの付着性が高まることで主筋又は配力筋間の連結強度が飛躍的に向上するせん断補強鉄筋を提供する。【解決手段】鋼棒１と、鋼棒を長手方向に並行な平面で分割した分割鋼棒２を備え、分割鋼棒は、分割面を介して鋼棒の少なくとも一端に主筋又は配力筋に掛止するために固定されていて、分割面の幅は、鋼棒の直径よりも大きく、分割鋼棒は鋼棒を半割りにした形状とされていて、鋼棒と分割鋼棒は摩擦圧接により固定されている。【選択図】図１
