SPACER FOR REINFORCEMENT, REINFORCED CONCRETE STRUCTURE, AND METHOD FOR CONSTRUCTING THE SAME
To provide a spacer for a reinforcement capable of easily moving and correcting a mounting position and efficiently performing the work for assembling the reinforcement in a lattice shape and the work for mounting the spacer for the reinforcement.SOLUTION: A spacer for a reinforcement comprises: a body including a first vertical reinforcement clamping piece part 111 abutting on a vertical reinforcement, a lateral reinforcement placing part 113 arranged outside the first vertical reinforcement clamping piece part to support a lateral reinforcement, a right wing piece part 114 and a left wing piece part erected on the outer side and the upper side of the lateral reinforcement placing part, an extended part 118 extending outward from the lateral reinforcement placing part, a rotation connection part 119 arranged inside the first vertical reinforcement clamping piece part, and a first rotating direction regulation piece part 112 having a cylindrical curved surface shape; and a rotary body including a second vertical reinforcement clamping piece part 121 rotatable at the rotation connection part and a second rotating direction regulation piece part 122 having a cylindrical curved surface shape. The spacer for the reinforcement constitutes a vertical reinforcement clamping mechanism in which the first vertical reinforcement clamping piece part and the second vertical reinforcement clamping piece part face each other and clamp the vertical reinforcement at the time of closing rotary motion of the rotary body, and has a mechanism for regulating release rotation by the first and second rotating direction regulation piece parts.SELECTED DRAWING: Figure 1
【課題】装着位置の移動・修正が容易であり、鉄筋を格子状に組む作業と鉄筋用スペーサの装着作業とを効率よく行える鉄筋用スペーサーを提供する。【解決手段】縦筋に当接する第一縦筋挟持片部１１１と、第一縦筋挟持片部より外側に配置され横筋を支承する横筋載置部１１３と、横筋載置部の外側かつ上側に立設する右翼片部１１４、左翼片部と、横筋載置部から外側に延在する延出部１１８と、第一縦筋挟持片部より内側に配置される回動連結部１１９と、円筒曲面状の第一回動方向規制片部１１２とを備え、回転連結部で回動自在な第二縦筋挟持片部１２１と、円筒曲面状の第二回動方向規制片部１２２とを備えた回動体からなり、回動体が閉鎖回動したときに、第一縦筋挟持片部と第二縦筋挟持片部とが、対向して縦筋を挟持する縦筋挟持機構を構成し、かつ第一・第二回動方向規制片部により解放回動を規制する機構を有することを特徴とする鉄筋用スペーサ。【選択図】図１
