SPACER FOR REINFORCING BAR ARRANGEMENT
To provide a spacer for reinforcing bar arrangement which stably supports a reinforcement grid without being deformed at the time of reinforcing bar arrangement, secures a uniform cover thickness of concrete at the time of placing concrete, exhibits an excellent construction strength and durability of concrete, and eliminates an extra time and labor for manually positioning the reinforcement or a reinforcement placing part after the reinforcing bar arrangement and finely adjusting the mutual arrangement state.SOLUTION: A spacer 100 for reinforcing bar arrangement includes: a strip-like reinforcement placing part 110 bent and formed along a construction flat surface G on which a reinforcement grid BM is laid; and a plurality of reinforcement support leg parts 120 vertically provided from the reinforcement placing part 110 toward the construction flat surface G. The spacer 100 for reinforcing bar arrangement is used for placing concrete containing coarse aggregate on the construction flat surface G, in which a conical projecting part 130 projecting from the reinforcement placing part 110 toward the reinforcement grid BM is integrally formed with the reinforcement placing part 110.SELECTED DRAWING: Figure 3
【課題】配筋時に鉄筋格子を変形させることなく安定して支持し、コンクリート打設時にコンクリートの均一なかぶり厚さ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し、配筋後の鉄筋または鉄筋載置部を人手で位置合わせしたり、相互の配置状態を微調整したりする余計な手間を省く配筋用スペーサを提供すること。【解決手段】鉄筋格子ＢＭを敷設する施工平坦面Ｇに沿って屈曲形成した帯板状の鉄筋載置部１１０とこの鉄筋載置部１１０から施工平坦面Ｇ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から鉄筋格子ＢＭに向けて突出する錐状突起部１３０が、鉄筋載置部１１０と一体に形成され、施工平坦面Ｇ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３
