CRACKING PREVENTING METHOD OF REMAINING FORMWORK PANEL, AND REMAINING FORMWORK PANEL
To provide a cracking preventing method of a remaining formwork panel and a remaining formwork panel used in the preventing method which prevents cracking generated in a remaining formwork panel by shrinkage force of concrete.SOLUTION: In a cracking preventing method of a remaining formwork panel, a connected metal fitting 3 covered with an elastic resin cover material 4 is provided in a panel body 2 at a range which is at least 10 mm from a back face of the panel body 2 in a remaining formwork panel 1. After constructing a remaining formwork 10, concrete 12 is installed and cured. A part covered with the elastic resin cover material 4 of the connected metal fitting 3 is not compacted by the concrete 12. A cracking displacement generated by shrinkage of the concrete 12 and a cracking displacement generated by external force in the concrete 12 are not hardly transferred to the panel body 2 by elastic displacement follow-up function and the like of the elastic resin cover material 4. Thus, generation of cracking in the remaining formwork panel 1 after construction is prevented.SELECTED DRAWING: Figure 1
【課題】本発明は、コンクリートの収縮力によって残存型枠パネルへ生じるひび割れを抑止する残存型枠パネルのひび割れ抑止方法、及びこの抑止方法に用いる残存型枠パネルを提供する。【解決手段】残存型枠パネルのひび割れ抑止方法は、残存型枠パネル１のパネル本体２の背面から少なくとも１０ｍｍの範囲を弾性樹脂製カバー材４で覆われた被連結金具３が、パネル本体２に設けられ、残存型枠１０の構築後に、コンクリート１２を打設し、硬化させ、被連結金具３の弾性樹脂製カバー材４で覆われた部分は、コンクリート１２によって固められず、コンクリート１２の収縮によって生じるひび割れ変位や外力によるコンクリート１２に生じるひび割れ変位が弾性樹脂製カバー材４の弾性変位追従機能等により、パネル本体２にほとんど伝わらない。これにより、施工した後に、残存型枠パネル１にひび割れが生じることが抑止される。【選択図】図１
