CRACKING PREVENTION STRUCTURE FOR CONCRETE STRUCTURE BODY
To provide a cracking prevention structure for concrete structure body that suppress temperature cracking due to external restriction to prevent a structure body surface from cracking.SOLUTION: A cracking prevention structure for concrete structure body has a reinforcing bar structure 10 for temperature cracking suppression embedded in a temperature stress predominant region 9 where temperature stress due to heat of hydration becomes larger inside main reinforcing bars 6, 6 arranged at the surface part of the concrete structure body 3 than at the surface part so as to prevent cracking occurring to the surface of the concrete structure 3, wherein the reinforcing bar structure for temperature cracking suppression is formed by arranging a plurality of reinforcing bars 12, 12, ..., for temperature cracking suppression, directed crossing a longitudinal section of the concrete structure body, at intervals in a longitudinal direction.SELECTED DRAWING: Figure 1
【課題】外部拘束による温度ひび割れを抑制し、構造物表面のひび割れを防止するコンクリート構造物のひび割れ防止構造の提供。【解決手段】コンクリート構造物のひび割れ防止構造は、コンクリート構造物３の表面部に配置された主筋６，６より内側の水和熱に起因する温度応力が表面部より大きくなる温度応力卓越領域９内にコンクリート構造物の縦断面と交差する方向に向けた複数の温度ひび割れ抑制用鉄筋１２，１２…が縦方向に間隔をおいて配置されてなる温度ひび割れ抑制用鉄筋構造１０が埋設されていることにより、コンクリート構造物３の表面に生じるひび割れを防止することができる。【選択図】図１
