PROBLEM TO BE SOLVED: To provide a crack-inducing joint sealant that reliably prevents water immersion into a concrete structure and water leakage from the structure.SOLUTION: A crack-inducing joint sealant includes: a holder 2 having a straight cutout formed at the center of a deep inside part 21 and an extension flap formed on each side of the outside of the deep inside part 21 in the direction of extension, as well as a bolt hole formed on the joint side part 22 on the opposite side; a crack-inducing plate 3 having a flange formed on both side edges of a plate-like body and protrusions formed on both sides of the plate-like body; a fixing bolt 4 comprising a thread part and a base 4b; a fixing nut 5; and a water cutoff packing 9 having a circular hole formed at the center. The total of the outer dimensions of a holder insertion part of the crack-inducing plate 3, the thickness dimension of the base of the fixing bolt 4, and the thickness dimension of the water cutoff packing 9 is set to be larger than the dimension from the inner surface of the deep inside part 21 of the holder 2 to the inner surface of the joint side part 22.
【課題】コンクリート構造物内部への浸水及び構造物内部からの漏水を確実に防止することができるひび割れ誘発目地材を提供する。【解決手段】奥側部２１の中央に直状の切欠が形成され、奥側部２１の延長方向外側に延長フラップがそれぞれ形成され、反対側の目地側部２２にボルト孔が形成されたホルダー２と、板状本体の両側縁にフランジが形成され、板状本体から両側方へ突出する突条が形成されたひび割れ誘発プレート３と、ねじ部及びベース４ｂからなる固定ボルト４と、固定ナット５と、円形の孔が中央に形成された止水パッキン９とによって構成され、ひび割れ誘発プレート３におけるホルダー挿入部分の外寸と、固定ボルト４のベースの厚さ寸法と、止水パッキン９の厚さ寸法の合計寸法が、ホルダー２における奥側部２１の内側面から目地側部２２の内側面までの寸法よりも大きく設定されていることを特徴とする。【選択図】図１
