To provide a top end pointer capable of being used conveniently for indicating a finishing level of a concrete layer to be installed.SOLUTION: A top end pointer main body 1 is composed of a rod-like main body 3 and a supporting threaded shaft 4. The rod-like main body 3 includes: a drawing operation portion 5 at an upper end; a projecting portion 6 for displaying the top end level provided on the rod-like main body 3 at a lower side of the drawing operation portion 5; and a connecting hole 7 opened at a lower end of the rod-like main body 3 and having a diameter smaller than an outer diameter of the supporting threaded shaft 4 and concentric with the rod-like main body 3. The rod-like main body 3, all of which is molded of elastic material as one body, is externally fitted and fixed elastically to an upper end portion of the supporting threaded shaft 4 so as to be possible to be pulled out through the connecting hole 7, a through screw hole 18 capable of screwing a lower end side of the supporting threaded shaft 4 of the top end pointer main body 1 in a freely advancing and retracting manner is provided in a mounting metal fitting 2 to the reinforcing bar.SELECTED DRAWING: Figure 1
【課題】打設するコンクリート層の仕上げレベルを表示するために便利に使用出来る天端ポインターを提供する。【解決手段】天端ポインター本体１は、棒状本体３と支持用螺軸４とから構成され、棒状本体３は、上端の引き抜き操作部５、引き抜き操作部５の下側で棒状本体３に設けられた天端レベル表示用張出し部６、及び棒状本体３の下端に開口し且つ支持用螺軸４の外径より小径で棒状本体３と同心状の連結孔７から成るもので、その全体が弾性材料から一体成型されたものであって、支持用螺軸４の上端部に棒状本体３が、連結孔７を介して引き抜き可能に弾性に抗して外嵌固定され、鉄筋への取付け金具２には、天端ポインター本体(1)１の支持用螺軸４の下端側を進退自在に螺嵌させることが出来る貫通ネジ孔１８が設けられた構成。【選択図】図１
