The external sash 1 to which the support fittings 6 and 7 are attached is firmly attached to the wall structure member 9 attached to the inner peripheral surface of the window opening W via the anchor members 6 and 7 by welding means or the like. The locking pieces 2N, 3F of the upper and lower frames 2, 3 and the indoor side parts of the doorstop webs 4A, 5A of the left and right vertical frames 4, 5 are installed so as to be located inward from the inner peripheral edge of the window opening W. It is being

In the figure, 10 is a glass shoji installed on the external sash 1, 11 is a screen door, and 12 is a window opening W.
13 is the interior material, 14 is the interior shoji installed on the frame frame, 15 is the window opening W and the frame frame 1
Sealing material filled on the outdoor side of the gap between 2 and 16
17 is a caulking member filled in the groove 1A on the peripheral edge of the external sash 1, and 17 is a drainage member attached to the groove 1A on the upper frame 2 side in a shielding manner.

Next, the operation and effects of this embodiment configured as described above will be explained.

Now, this external sash 1 is an external sash 1 that is attached to the outdoor side of a window opening W, and includes an upper frame 2, a lower frame 3, and a vertical frame 4 on the left and right sides of the external sash 1.
Contact pieces 6A, 7 of support fittings 6, 7 are attached to the indoor side of 5.
In addition to providing support surfaces 2V, 3T, 4M, and 5M that contact A, the support surfaces 2V, 3T, 4M, and 5M are provided.
The locking pieces 2N, 3F and the doorstop webs 4A, 5A that become part of the window opening W are formed inwardly from the inner peripheral edge of the window opening W, and the mounting pieces 6C, 7C of the support fittings 6, 7 are attached to the window opening W. The contact piece 6A of the support fitting 6 on the lower frame 3 side is welded to the wall structure material 9 disposed on the inner periphery.
A support piece 6B is provided at the lower part of the frame 3 so as to protrude toward the outdoors and support the lower frame 3 side. Therefore, the external sash 1 has a support surface 2 provided on the indoor side of its upper frame 2, lower frame 3, and left and right vertical frames 4, 5.
Contact pieces 6A, 7 that contact V, 3T, 4M, 5M
Since the support fittings 6 and 7, which are made up of A and mounting pieces 6C and 7C extending into the window opening W, are screwed together with screws 8B, the structural strength and support strength of the sash 1 itself can be increased. In addition, the welding of the support fittings 6, 7 to the wall structure material 9 can be performed extremely labor-savingly without the need for the support fittings 6, 7 and the sash 1 to come loose. On the lower edge side of part W, the support metal fitting 6
It is stably supported in a mounted manner by the engagement support piece 6B, and can be firmly attached to the window opening W. In addition, the locking pieces 2N, 3F that become part of the support surfaces 2V, 3T, 4M, 5M and the doorstop webs 4A, 5A
is positioned inward from the inner peripheral edge of the window opening W, making it easy to install the frame frame 12 and the interior material 12 using the locking pieces 2N, 3F and the doorstop webs 4A, 5A as installation standards. There are many features such as what you can do.

Although the illustrated angle material 9 is used as the wall structural material 9, it may be a structural material that is embedded in the wall, for example, as shown by the two-dot chain line in the drawing.

Now, the present invention is an external sash that is attached to the outdoor side of a window opening, and a support surface is provided on the indoor side surface of each frame of the external sash to which the contact piece of the support fitting comes into contact, and the support surface The mounting piece of the support fitting is welded to the wall structure material disposed on the inner periphery of the window opening by forming at least a part of it inward from the inner periphery of the window opening, and furthermore, A support piece is provided below the abutment piece of the support fitting to project outdoors and support the lower frame side. Therefore, the external sash has a support consisting of contact pieces that come into contact with the support surfaces provided on the indoor side of the upper frame, lower frame, and left and right vertical frames, and mounting pieces that extend into the window opening W. Since the metal fittings are attached, the structural strength and support strength of the sash itself can be increased, and the welding of the supporting metal fittings to the wall structure material is extremely labor-saving as there is no disconnection between the supporting metal fittings and the sash. In addition, the sash can be stably supported in a resting manner by the engaging support piece of the support fitting, particularly on the lower edge side of the window opening, and can be firmly attached to the window opening. In addition, since a part of the support surface is positioned inward from the inner peripheral edge of the window opening, it is possible to easily install the frame frame and interior materials using the same part as the installation reference. This is an extremely practical idea for a satsushi.
