POST-INSTALLED ANCHOR AND DETERIORATION INSPECTION METHOD OF CONCRETE CONSTRUCTION
To provide a post-installed anchor and a concrete construction deterioration inspection method allowing a deterioration check of the anchor to be easily performed in low cost.SOLUTION: An insertion hole 2 having a diameter expansion section 5 the larger in diameter than an opening 3 in a depth side is secured in a formed concrete construction 1. The insertion hole has an elongated anchor bars 11 and an engaging part 12. The anchor bar 11 is inserted in the insertion hole 2, of which a tip projects from the insertion hole 2, comprising markers 7, 8 positioned at a position corresponding with the opening 3 or at a predetermined position on a rear end side further than that of the opening 3 to confirm deterioration of the concrete construction. The engaging part 12 is arranged on a rear part of the anchor bar 11 and is positioned at the diameter expanding section 5. The anchor bar 11 and the engaging part 12 are secured in the insertion hole 2 with adhesive 6.SELECTED DRAWING: Figure 1
【課題】アンカーの劣化を低コストで容易に確認することができるあと施工アンカーおよびコンクリート構造劣化検査方法を提供する。【解決手段】開口３より大径の拡径部５を奥側に有する挿入穴２が形成されたコンクリート構造物１に固定される。細長いアンカー筋１１と係合部１２とを有する。アンカー筋１１は挿入穴２に挿入され、先端が挿入穴２から突出し、開口３と一致する位置または開口３より後端側の所定の位置にコンクリート構造の劣化を確認するための目印７，８を有する。係合部１２はアンカー筋１１の後部に設けられて拡径部５に配置される。アンカー筋１１および係合部１２は接着剤６で挿入穴２に固定される。【選択図】図１
