To prevent a holding metal fitting and a diameter expansion anchor for attaching a peeling prevention sheet from falling off a concrete structure.SOLUTION: A peeling prevention sheet 2 is laid so as to substantially follow a mounting surface 101 of a concrete structure 100. A holding metal fitting 1 having a front plate 11 and a back plate 12 is provided so as to sandwich the vicinity of both edges in the width direction of the peeling prevention sheet 2 with the back plate 12 facing the mounting surface 101. Each of vertical shape retaining members 221 at the edges in the width direction of the peeling prevention sheet 2 is accommodated in a protruding stepped portion 14 of the front plate 11. A diameter expansion anchor 3 is cast into the concrete structure 100 through a front through hole 16 and a back through hole 17. The holding metal fitting 1 is pressed toward the mounting surface 101 by a nut 4 screwed onto the diameter expansion anchor 3. The vertical shape retaining member 221 is pressed toward the mounting surface 101 by the holding metal fitting 1, and the peeling prevention sheet 2 is attached.SELECTED DRAWING: Figure 2
【課題】剥落防止シートを取り付ける押さえ金具と拡径アンカーがコンクリート構造物から脱落することを防止できる。【解決手段】剥落防止シート2がコンクリート構造物100の取付面101に略沿うように敷設され、正面板11と背面板12を有する押さえ金具1が、背面板12を取付面101側にして剥落防止シート2の幅方向の両端縁付近を挟み込むように設けられ、且つ剥落防止シート2の幅方向の端縁の縦保形材221のそれぞれが正面板11の張出段差部14に収容され、正面貫通穴16と背面貫通穴17を通して拡径アンカー3がコンクリート構造物100に打設され、拡径アンカー3に螺合されたナット4で押さえ金具1が取付面101側に押圧され、この押さえ金具1で縦保形材221が取付面101側に押圧されて剥落防止シート2が取り付けられている剥落防止構造。【選択図】図2
