Can be fixed to each of the reference fixed sides 12, 41, 51 of the remodeling cubicle 10, the existing vertical frame 4, and the upper frame 2 by screwing from the indoor side, so that the mounting structure of the vertical frame 30 to the cubic 10 and the existing The mounting structure of the upper frame 50 and the vertical frame 40 with respect to the frames 2 and 4 can be made the same, so that the workability can be improved, and each of the vertical frames 30 and 40 can be composed of the same or similar frames, and the parts can be shared. And productivity can be improved. Also, the new lower frame 60 can be fixed only by screwing the base material 62 to the existing lower frame 3 and, like the other new vertical frames 30, 40 and the upper frame 50, can be attached by work from the indoor side. Therefore, workability can be further improved.

The present invention is not limited to the above embodiments. For example, in the above embodiment, the new vertical frame 40 connected to the existing vertical frame 4 is a vertical frame having an external attachment 45, but the same external attachment as the vertical frame 30 connected to the cubic 10 is connected. Instead, a vertical frame in which the part is integrated may be used. Further, the upper frame 50 may be of a type having no external attachment like the vertical frame 30.

Further, in the above-described embodiment, a case has been described in which the new aluminum window frame 20 is installed on the existing steel window frame 1. However, the new aluminum window is installed on the existing aluminum window frame. The present invention can be applied to the case where the frame 20 is installed.

Further, the vertical frame 40 and the upper frame 5 of the new window frame 20
Although 0 is fixed to the base materials 42 and 52 via the anchor 70, it may be directly screwed to the base materials 42 and 52 without using the anchor 70. In addition, the shapes, materials, and the like of the vertical frames 30, 40, the upper frame 50, the lower frame 60, the external attachments 45, 55, the frames 46, 56, 66, the drainers 65, the anchors 70, etc. of the new window frame 20 are remodeled. What is necessary is just to set suitably according to the shape of the window to be performed.
