Claims (5)
- コンクリート等に作為的にひび割れを発生させて、ひびわれに対する補修実験に供するひび割れ供試体であって、
コンクリート等からなる上面略矩形の板体の裏面に、炭素繊維集成板からなる帯状の拘束体を、板体の対角線状に交差させて貼着してなるひび割れ供試体。 - 板体の裏側から拘束体の交差部分を打撃して、板体の表側にひび割れを発生させたことを特徴とする請求項1に記載のひび割れ供試体。
- 請求項2に記載のひび割れ供試体におけるひび割れの内部に注入材を注入した後、該注入部分を切断して注入材の状態を確認することを特徴とするひび割れ補修実験方法。
- 請求項2に記載のひび割れ供試体におけるひび割れの内部に注入材を注入した後、注入材の硬化後に再度、板体の裏側から拘束体の交差部分を打撃して、板体の表側にひび割れを発生させることを特徴とするひび割れ補修実験方法。
- 請求項1に記載のひび割れ供試体における表面中央部分の適宜範囲に弾性塗料を塗布した後、該ひび割れ供試体の裏側から拘束体の交差部分を打撃して、板体の表側の上記塗布範囲周辺にひび割れを発生させることを特徴とするひび割れ補修実験方法。
