REMOVAL MECHANISM OF WEDGE MEMBER FOR MAINTENANCE OF FATIGUE CRACK, LOADING METHOD OF WEDGE MEMBER FOR MAINTENANCE OF FATIGUE CRACK, AND REMOVAL METHOD OF WEDGE MEMBER FOR MAINTENANCE OF FATIGUE CRACK
To provide a removal mechanism of a wedge member for maintenance of a fatigue crack, a loading method of the wedge member for maintenance of the fatigue crack, and a removal method of the wedge member for maintenance of the fatigue crack.SOLUTION: A removal mechanism used for removing a wedge member 10 for maintenance includes a first slope component 11 that is fitted into a stop hole 3 provided with respect to a fatigue crack 2 to suppress a stress variation width of a structure 1, a second slope component 12, and mounting load application means which applies a load in a direction in which the second slope component 12 slides on the first slope component 11 and rises gradually. The removal mechanism includes removal load application means (bolt 14) which applies a load in a direction in which the second slope component 12 slides on the first slope component 11 and goes down gradually. When the wedge member 10 for maintenance is removed from the stop hole 3, a removal load is applied by the removal load application means (bolt 14).SELECTED DRAWING: Figure 1
【課題】疲労亀裂の補修用くさび部材の取り外し機構、疲労亀裂の補修用くさび部材の装着方法、及び疲労亀裂の補修用くさび部材の取り外し方法を提供する。【解決手段】疲労亀裂２に対して設けたストップホール３にはめ込んで構造物１の応力変動幅を抑制するための第１斜面部品１１と、第２斜面部品１２と、第２斜面部品１２が第１斜面部品１１上を摺動しせり上がる方向の荷重を付与する装着荷重付与手段を備えた補修用くさび部材１０の取り外しに用いる取り外し機構であって、第２斜面部品１２が第１斜面部品１１上を摺動しずり下がる方向の荷重を付与する取り外し荷重付与手段（ボルト１４）を備え、補修用くさび部材１０のストップホール３からの取り外し時に、取り外し荷重付与手段（ボルト１４）により取り外し荷重を付与する。【選択図】図１
