REPAIR METHOD OF DIRT-FLOOR CONCRETE OF EXISTING STRUCTURE
PROBLEM TO BE SOLVED: To connect a part between dirt-floor concrete and a dispersion beam in high strength by simple work.SOLUTION: A connection bolt 21 for connecting a part between deformed dirt-floor concrete 10 and a dispersion beam 20 and an open leg anchor 60 having a plurality of anchor legs 61 and a convergence nut 62 are used, and after opening a connection hole 17 opened in the dirt-floor concrete 10, a diameter expanded space 43 is formed under the dirt-floor concrete 10, and a diameter expanded pressure receiving board 52 is formed by filing a consolidation material in the diameter expanded space 43 for installing the open leg anchor 60, and a part between the dirt-floor concrete 10 and a lower part of the connection bolt 21 is connected in high strength via the diameter expanded pressure receiving board 52.SELECTED DRAWING: Figure 8
【課題】簡単な作業で以って土間コンクリ−トと分散梁間を高強度に連結すること。【解決手段】変形した土間コンクリート１０と分散梁２０の間を連結する連結ボルト２１と、複数のアンカー脚６１と収束ナット６２を具備した開脚アンカー６０とを使用し、土間コンクリ−ト１０に開設した連結孔１７を開設した後に、土間コンクリート１０の下方に拡径空間４３を形成し、開脚アンカー６０を設置した拡径空間４３内に固結材を充填して拡径受圧版５２を形成し、拡径受圧版５２を介して土間コンクリート１０と連結ボルト２１の下部との間を高強度に連結する。【選択図】図８
