To prevent generation of a cavity in a communication hole that extends from a grout type filling type joint in a concrete member and is filled with a grout material.SOLUTION: A plug 40 is fit into an opening 22 of a communication hole 21. The communication hole 21 has one end connected to a grout discharge port 14 of a reinforcement joint 10 in a precast concrete column 1 and the other end opened to an outer surface of the concrete column 1. The plug 40 has a plug body 41 and a tube 50. One end of the plug body 41 is fit into the opening 22. The plug body 41 has a through hole 45 formed so as to be connected to a side face of a body part 43 from a small diameter side end face 42a of a base part 42. The tube 50 is transparent, and has one end inserted to the through hole 45 of the plug body 41. The other end of the tube 50 is arranged so as to be higher than the opening 22.SELECTED DRAWING: Figure 3
【課題】コンクリート部材内でグラウト充填式継手から延びてグラウト材が充填された連通孔に、空洞が発生することを防止する。【解決手段】止栓４０は、連通孔２１の開口２２に嵌め込まれる。連通孔２１は、プレキャストコンクリート柱１内の鉄筋継手１０のグラウト排出口１４に一端がつながり他端がコンクリート柱１の外面に開口している。止栓４０は、栓本体４１とチューブ５０を有する。栓本体４１の一端部は、開口２２に嵌め込まれる。栓本体４１は、基部４２の小径側端面４２ａから胴部４３の側面に連なるように形成された貫通孔４５を有する。チューブ５０は透明であって、その一端部が栓本体４１の貫通孔４５に挿入されている。チューブ５０の他端は開口２２より高く配置されている。【選択図】図３
