In the present invention, a reinforcing wedge anchor is prepared by comprising a wedge bolt, a first wedge part inserted into the end part of the wedge bolt, and a gap maintaining part inserted into the wedge bolt. The objective of the present invention is to maintain firm fixing force by making the outer circumference of the first wedge part receiving pressurizing force by the forward movement of the wedge bolt swell to be attached to the inner circumference of a through hole of a bearing wall. Accordingly, a wedge anchor for reinforcing a masonry wall of the present invention reinforces a masonry wall in order to prevent the escaping of an existing masonry wall in the process of repairing the masonry wall. The wedge anchor for reinforcing a masonry wall comprises a wedge bolt (10) which comprises a head part (12) with a machine tool groove (18) of a predetermined depth, a fixing shaft (14) expanding with a smaller outer diameter than that of the head part (12), and a spiral part (16) formed at the end part of the fixing shaft (14); a first wedge part (20) which has a containing space (22) inside for allowing the end part of the wedge bolt (10) to be inserted, a fastening part fastened with the spiral part (16) on one side, and an expansion inducing hole (26) for facilitating expansion by pressurizing force on the outer circumference; and a gap maintaining part (30) with a predetermined length which is inserted into the fixing shaft (14) of the wedge bolt (10), pressurizes the first wedge part (20) by forward pressurizing force based on rotation of the wedge bolt (10) to apply firm fixing force to the inner circumference of the through hole (P) of the bearing wall (I). |
