PROBLEM TO BE SOLVED: To provide a bar-arrangement spacer for exhibiting excellent construction strength and durability of concrete, by securing a sufficient placing quantity and a predetermined uniform cover thickness C of the concrete when placing the concrete, by stably supporting a reinforcement in a state of holding a spacer form when placing the reinforcement.SOLUTION: A bar-arrangement spacer 100 comprises a reinforcement placing part 110 bent-formed along a construction flat surface CS for laying a reinforcement and a plurality of reinforcement support leg parts 120 suspended toward the construction flat surface CS from this reinforcement placing part 110, in which the reinforcement placing part 110 is formed in a band plate shape along the construction flat surface CS, and the reinforcement support leg part 120 is formed in a tapering-off shape toward the construction flat surface CS, and is used when concrete of including a coarse aggregate is placed the construction flat surface CS.SELECTED DRAWING: Figure 1
【課題】鉄筋載置時にスペーサ形態を保持した状態で鉄筋を安定して支持するとともに、コンクリート打設時にコンクリートの充分な打ち込み量と所定の均一なかぶり厚さＣを確保してコンクリートの優れた施工強度と耐久性を発揮する配筋用スペーサを提供すること。【解決手段】鉄筋を敷設する施工平坦面ＣＳに沿って屈曲形成した鉄筋載置部１１０とこの鉄筋載置部１１０から施工平坦面ＣＳに向けて垂設した複数の鉄筋支持脚部１２０とを備え、鉄筋載置部１１０が、施工平坦面ＣＳに沿った帯板状に形成され、鉄筋支持脚部１２０が、施工平坦面ＣＳに向けて先細状に形成され、施工平坦面ＣＳ上に粗骨材を含むコンクリートを打設する際に用いる配筋用スペーサ１００。【選択図】図１
