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
