To provide a spacer for reinforcement allowing changing of covering depth of reinforcement with a single spacer, without preparing multiple spacers for reinforcement for every protrusion amount of each positioning protrusion.MEANS FOR SOLVING THE PROBLEM: As a spacer for reinforcement for holding a space between a fitted horizontal reinforcement and a form, a reinforcement engaging part 11 engaging a horizontal reinforcement Y in an inserted state inside from an insertion hole 12 opened in the circumferential direction, and a first and a second positioning protrusions 2, 3 fan-likely protruded outward in the radial direction from a position with a space in the circumferential direction at an outer periphery of the reinforcement engaging part 11, and making every protrusion end abut on the surface of a form K are provided. The first and the second positioning protrusions 2, 3 have different protrusion lengths from the reinforcement engaging part 11 of every positioning protrusions 2, 3 to the protrusion ends.SELECTED DRAWING: Figure 1
【課題】各位置決め突起部の突出量毎に鉄筋用スペーサーを複数用意しなくても、単一で鉄筋のかぶり厚をそれぞれ変更することが可能な鉄筋用スペーサーを提供する。【課題手段】装着される横筋と型枠との間隔を保持する鉄筋用スペーサーとして、横筋Ｙを周方向に開口する挿通孔１２から内部に挿通した状態で嵌合する鉄筋嵌合部１１と、鉄筋嵌合部１１の外周において周方向へ間隔を隔てた位置より半径方向外方向きにそれぞれ扇状に突出し、それぞれの突出端を型枠Ｋの表面に対し選択的に当接させる第１及び第２位置決め突起部２，３と、を備える。第１及び第２位置決め突起部２，３は、当該各位置決め突起部２,３毎の鉄筋嵌合部１１から突出端までの突出長さをそれぞれ異ならせている。【選択図】図１
