[Problems to be solved by the device]

 As described above, it is necessary to accurately attach the sash frame 24 to the opening portion 21 of the wall surface 20 when attaching the sash frame. Therefore, as shown in FIG. 8, the mounting position is accurately adjusted using the wedge 25. The adjustment work using the wedge 25 is very difficult and requires skill, and special construction technology such as a sash construction technician is required.

Various devices have been developed to smoothly perform the time-consuming position adjustment work. For example, in Japanese Patent Laid-Open No. 58-584, as shown in FIG. 9 (1), a sash frame 31 is fixed by using a fixing member 30 in the form of a simple jack. However, this fixing bracket requires a wide mounting space due to its structure, and therefore cannot be mounted unless the gap between the sash frame 31 and the wall surface 32 is wide to some extent. Also, in the case of aluminum sash, there is a problem with the strength of the frame, so it is necessary to pay sufficient attention to deformation when pressing it from the outside to fix it.

Further, in Japanese Utility Model Laid-Open No. 56-124174, as shown in FIG. 9 (2), a nut 34 is welded and fixed to the center of a sash anchor 33 to be locked to a sash frame, and a bolt 35 is attached. The fixing position of the sash frame is adjusted by adjusting the protruding length of the bolt 35. The adjustment can be easily done by turning the bolt 35, but the adjustment range is only the gap between the sash anchor 33 and the sash frame, and there is only about 20 mm, so when the gap between the wall surface and the sash frame is large. Cannot be used for. Further, since the mounting is performed at a pitch of about 400 mm, the number of adjustment points is increased, and furthermore, since the sash frame is pressed and fixed, there is a problem of frame deformation.

The present invention has been made in view of the above-mentioned conventional problems, and is capable of easily and accurately fixing the sash frame, and is highly reliable without fear of deformation of the sash frame. This was done to realize a jig for fixing the frame.
