PROBLEM TO BE SOLVED: To provide an earthquake-resisting reinforcement method for concrete column-beam structures, which: can make it adept, simple and unerring to join a column-beam structure consisting of columns and beams and a RC earthquake-resisting wall which is built in the inner region of the structure; and can make earthquake-resisting construction efficient.SOLUTION: An earthquake-resisting reinforcement method for concrete column-beam structures in this invention comprises: a drilling process which drills anchor holes 15, 17 in the upper surface 5a of a lower beam 5 to which an earthquake-resisting wall is joined; a dummy reinforcement bar placement process in which dummy reinforcement bars 19 are inserted into the anchor holes and are made to protrude into the inner space X of the structure; a belt-like plate bonding process which sticks a belt-like plate 11 with through holes 11b formed on it to the upper surface of the lower beam; a dummy reinforcement bar removal process which removes the dummy reinforcement bars before they are adhered to the belt-like plate; a post-process anchor-fixing process, in which post-process anchors are fixed on the lower beam to protrude into the inner space of the structure by filling the anchor holes with a filler and inserting the post-process anchors into the anchor holes via the through holes; and an earthquake-resisting wall building process in which wall reinforcement bars are arranged in the inner space of the structure and wall concrete is cast.SELECTED DRAWING: Figure 5 |
