Abstract: PROBLEM TO BE SOLVED: To provide a new method for repairing a fitting frame, which uses an existing frame as it is, inserts a new frame into the existing frame to engage the former with the latter from the front while suppressing reduction in inner dimension of the existing frame to a possible minimum extent, directly anchors the new frame to a structural wall of a building without depending on the existing frame, and eliminates a problem caused by exposure of a small screw head and screw loosening due to screwing by means of small screws, to thereby achieve short-time work without a construction nuisance and reduction in construction cost. SOLUTION: According to the method, the new frame for enclosing a new door is engaged with the inside of the existing entrance fitting frame for renovation, and the new frame is fitted only into a fitting slot of a door stop tight member. After erecting and temporarily fastening the new frame, a crank anchor piece and a flat plate anchor piece which are obtained by working a hinge-screwing rear plate, are employed depending on application, and then an inner screw-type hole-in anchor is driven by using a hollow hole of the anchor piece, followed by space-screwing a taper washer into the hollow hole. Thus, the new frame can be accurately, effectively, and directly fixed to the structural wall without depending on the existing frame. Further, if the indoor-side frame is of a three-way casing type and the existing frame is covered with an arbitrary material, the renovation depending on an indoor environment can be implemented.
