REPAIR MEMBER OF FATIGUE CRACK
To provide an adaptive slope-type wedge member which is used for repairing a fatigue crack formed in a structure, and in which the gradual rising movement of a second slope part can be made smooth even when a slope gradient is comparatively large.SOLUTION: A repair member is fitted into a stop hole 3 and/or a wedge hole provided for a fatigue crack 2 formed in a structure to suppress a stress fluctuation range in the structure. The repair member includes: a first slope part 10 which has a slope 10a and is fitted into the stop hole 3 and/or the wedge hole; a second slope part 20 having a slope 20a which slides on the first slope part 10; and parallel energization force applying means which automatically applies energization force parallel to the slopes 10a and 20a to the second slope part 20 to apply, to the stop hole 3 and/or the wedge hole, a wedge load caused by the sliding and gradual rising of the second slope part 20 on the first slope part 10 when the stop hole 3 and/or the wedge hole is elongated.SELECTED DRAWING: Figure 1
【課題】構造物に生じた疲労亀裂の補修に用いる適応型の斜面型くさび部材に関し、斜面勾配が比較的大きい場合であっても第２斜面部品のせり上がり動作を円滑なものとすること。【解決手段】構造物に生じた疲労亀裂２に対して設けたストップホール３及び／又はウェッジホールにはめ込んで構造物の応力変動幅を抑制するための補修用部材であって、ストップホール３及び／又はウェッジホールにはめ込む斜面１０ａを有した第１斜面部品１０と、第１斜面部品１０上を摺動する斜面２０ａを有した第２斜面部品２０と、ストップホール３及び／又はウェッジホールの伸長時に第２斜面部品２０が第１斜面部品１０上を摺動しせり上がることにより生じるくさび荷重をストップホール３及び／又はウェッジホールに付与するため、斜面１０ａ，２０ａと平行の付勢力を第２斜面部品２０に自動的に付与する平行付勢力付与手段とを備える。【選択図】図１
