[Working process] The work of mounting the metal window frame 1 in the wall opening K of the present invention will be described in the order of the following steps (1) to (4). (1) First, as shown in FIG. 5, the strut fixing bracket A and the pressure receiving fixing bracket B are respectively opposed to the vertical and horizontal frames of the metal window frame 1, and the locking pieces 1 of the respective anchor main plates 2, 7 are engaged. 6, the both edges 1a of the metal window frame 1 are sandwiched and fixed.

(2) Then, as shown in FIG. 6, the metal window frame 1 is put in the wall opening K, and the metal window frame 1 is pressed by the spring 11 of the pressure receiving rod 10 of the pressure receiving fixture B.
The whole is temporarily fixed in the wall opening K. At this time, in the case where the pressure receiving fixing bracket B has a configuration in which the engagement / disengagement lever 13 is provided on the pressure receiving rod 10 (shown in FIGS. 7 and 8), the pressure receiving rod 10 is in a submerged state (see FIG. 8). (Shown), the entire metal window frame 1 can be inserted into the wall opening K without resistance. After that, the engaging lever 13 is pushed to make the pressure receiving rod 10 protrude (shown in FIG. 7), and the tip thereof is temporarily fixed to the inner wall surface of the wall opening K (FIG. 7).

(3) Next, as shown in FIG. 6, an adjusting nut 6 screwed to the male thread portion 4 of the projecting bar 5 of the projecting fixture A by applying a level S to the metal window frame 1 is provided. By rotating, the distance between the inner wall surface of the wall opening K and the both edges 1a of the metal window frame 1 is finely adjusted to expand and contract to accurately position and fix the metal window frame 1. At this time, on the side of the pressure receiving fixing bracket B, the pressure receiving rod 10 elastically interlocks with the fine adjustment movement of the metal window frame 1 by the adjustment nut 6 by the force of the spring 11, and automatically responds to the movement.

(4) Then, the strut fixing bracket A and the pressure receiving fixing bracket B fixed to the metal window frame 1 are welded directly or via an intermediate reinforcing bar to the buried reinforcing bar on the inner wall surface of the wall opening K. Then, the gap between the wall opening K and the metal window frame 1 is filled with mortar while the metal window frame 1 is fixed, and the metal window frame is finally fixed. Installation work is completed.
