In this case, the bay window 1 is lifted up to a position where the roof portion 1a exceeds the winch hanger 131. Here, the bay window 1 is pulled toward the existing window frame S together with the electric winch 132, and the bay window 1 is slightly lowered so as to be in the vertical posture so that the roof portion 1a of the bay window 1 does not collide with the eaves A. Then, the bay window 1 is placed on the winch hanger 131, and then guided by the winch hanger 131, and the bay window 1 is drawn to the existing window frame S again. Here, the window 1 is finely aligned, and the fixing bolts 84, 107, 124 are inserted through the outer brackets 81, 101, 121.
[0054]
Next, the nuts 84b, 107b, and 124b of the fixing bolts 84, 107, and 124 are screwed from the indoor side, and the bay window 1 is fastened to the holding members 61, 62, and 63. Then, the rider 135 and the sling chain 134 are removed, and the electric winch 132 is removed from the winch hanger 131. Further, the winch hanger 131 is removed from the existing window frame S, and the lifting jig 133 is removed from the bay window 1. Finally, the window air conditioner 5 and the outdoor unit are mounted, and the two-piece shoji 23 and the base plate 7 are incorporated in the bay window 1.
[0055]
As described above, according to the present embodiment, since the bay window 1 is sandwiched and fixed to the existing window frame S, the existing opening B side simply removes the shoji and does not require any special repair work. And the newly installed bay window 1 can be easily and quickly attached. At this time, the clamping members 61, 62, 63 are fixed to the existing window frame S in advance, and the actual fastening operation is performed between the fixing bolts 84, 107, 124 and the outer brackets 81, 101, 121. Therefore, the bay window 1 can be more easily and quickly attached. In addition, by providing the window frame seal member 77 at the sandwiching portion of the existing window frame S, the window frame seal member 77 can be strongly pressed against the existing window frame S by using the sandwiching force. Further, by providing seal pieces 76 in close contact with the opening B on the four circumferences of the inner window frame 21, by attaching the bay window 1 to the existing window frame S, the seal pieces 76 can be appropriately interposed. And the water blocking between the opening B can be improved.
[0056]
On the other hand, since the bay window 1 is lifted by the electric winch 132 installed in the opening (existing window frame S) B to which the bay window 1 is attached, there is no need to build a scaffold for repair work, and the downstairs or adjacent floor Dwelling units will not be affected by the renovation work.
[0057]
In this embodiment, each holding member is fixed to the existing window frame in advance, and the actual fastening operation (attachment operation) is performed between the fixing bolt and the outer bracket. The outer bracket may be fastened in advance, and the actual fastening operation may be performed at each of the holding members. In such a case, positioning of the bay window can be easily performed.
[0058]
【The invention's effect】
As described above, according to the bay window mounting structure of the present invention, the new bay window is attached to the existing window frame only by fastening the outer and inner clamping members that sandwich the existing window frame from the expected direction, The existing window frame can be utilized, and the bay window can be easily and quickly attached.
