CONSTRUCTION METHOD OF POST-CONSTRUCTION ANCHOR
To provide a construction method of a post-construction anchor capable of filling grout deep into a hole and capable of installing an anchor bar at a predetermined position in a hole.SOLUTION: A holding device 10 attached to a tip portion of a rod-like anchor bar 20 slidably along the anchor bar 20 and holding the anchor bar 20 is pressed into a hole bottom 4 of an anchor hole 3 that is formed in advance on a construction face 2 together with the anchor bar 20 (S2). Grout g is injected between the hole bottom 4 and the holding device 10 from an injection hole 13 provided in the holding device 10 (S3). When, by injecting the grout g, the holding device 10 slides in the anchor hole 3 to reach the construction face 2, injection of the grout g is stopped (S5). After the grout g is hardened, the holding device 10 is removed from the construction face 2 (S6).SELECTED DRAWING: Figure 5
【課題】孔の奥までグラウトを充填でき、かつ、アンカー筋を、孔内の所定位置に設置できるようにするあと施工アンカー施工方法を提供する。【解決手段】棒状のアンカー筋２０に沿ってスライド可能にアンカー筋２０の先端部に取り付けられた、アンカー筋２０を保持する保持装置１０を、施工面２に予め形成されたアンカー孔３の孔底４までアンカー筋３０と共に押し込み（Ｓ２）、保持装置１０に設けられた注入孔１３から、孔底４と保持装置１０との間にグラウトｇを注入し（Ｓ３）、グラウトｇの注入により保持装置１０がアンカー孔３をスライドして施工面２まで達したところで、グラウトｇの注入を止め（Ｓ５）、グラウトｇが硬化した後、施工面２から保持装置１０を取り外す（Ｓ６）。【選択図】図５
