POST-PROCESS ANCHOR CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a post-process anchor construction method which can prevent an opening end portion of a perforation formed in the existing structure and its vicinity from being damaged by the pressure from an anchor bar.SOLUTION: An anchor material has a plate-shaped flange portion 1b extending in a direction intersecting a bar-shaped anchor bar 1a. The anchor bar 1a has an in-perforation arrangement portion 1e and a projecting portion. The flange portion 1b is formed in an annular shape. When assuming a straight line S1 connecting an outer peripheral end portion of the flange portion 1b located at a position where a linear distance between an axis L of the anchor bar 1a and the outer peripheral end portion of the flange portion 1b becomes the shortest and the axis L of the anchor bar 1a, the linear distance between the outer peripheral end portion of the flange portion 1b and the axis L is 2.5 times or more as large as the linear distance between an outer peripheral end portion of the anchor bar 1a and the axis L, and the thickness of the flange portion 1b is 3 mm or more and 15 mm or less. A post-process anchor construction method comprises an anchor material arrangement step and an inorganic filler filling step, so that the entire flange portion 1b is buried in an inorganic filler within a perforation.SELECTED DRAWING: Figure 5
【課題】既存の構造物に形成された穿孔の開孔端部やその近傍がアンカー筋からの圧力によって破損してしまうのを抑制できるあと施工アンカー工法を提供する。【解決手段】アンカー材は、棒状のアンカー筋１ａと交差する方向に延びる板状のフランジ部１ｂとを備え、アンカー筋１ａは、穿孔内配置部１ｅと突出部とを備え、フランジ部１ｂは、環状に形成され、アンカー筋１ａの軸線Ｌとフランジ部１ｂの外周端部との間の直線距離が最短になる場所に位置するフランジ部１ｂの外周端部とアンカー筋１ａの軸線Ｌとを結ぶ直線Ｓ１を仮定した際に、フランジ部１ｂの外周端部と軸線Ｌとの間の直線距離は、アンカー筋１ａの外周端部と軸線Ｌとの間の直線距離に対して２．５倍以上であり、フランジ部１ｂの厚みは、３ｍｍ以上１５ｍｍ以下で、アンカー材配置工程と、無機系充填材充填工程とを備え、フランジ部１ｂの全体が穿孔内で無機系充填材に埋没するようにする。【選択図】図５
