The double sash S formed in this manner is fixed to the anchor member 19 disposed inside the wall of the window opening W by welding means or the like, and is also attached to the frame material 1.
1, 12, 13 mounting pieces 11C, 12C, 13C
The end portion thereof is brought close to the periphery of the wall of the window opening W and is fixed to the anchor member 19 to form a groove portion 20 as shown in the figure.The groove portion 20 is filled with caulking material 21 and the sash S The outdoor gap between the wall and the inner periphery of the wall is shielded.

In addition, in the figure, 22 is an outer glass shoji erected in a sliding manner on the outer frame 1, 23 is an inner glass shoji erected in a sliding manner on the inner frame 6, 24 is an interior frame material, and 25 is an interior wall. , 26 is a caulking member filled in the groove between the outer frame 1 and the frame material.

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

Now, the double sash S of this example is made by connecting the outer frame 1 and the inner frame 6 with joint materials 14, 15, 16.
6 is a convex portion 14B that is attached to the back side of both the frames 1 and 6, and is sandwiched between the inner and outer frames 1 and 6;
Attachment pieces 2J, 3G, 4 having 15C and 16B and protruding toward the outer circumference from the outdoor end of the outer frame 1
Contact pieces 14C, 15E, 16 that contact H, 5H
C is provided, and at least the joint material 14,1
5, 16 indoor side connecting pieces 14A, 15A, 16
A, the convex parts 14B, 15C, 16B and the contact pieces 14C, 15E, 16C on the outdoor side are connected to both the frames 1, 6 by fastenings 18A, 18B, 18C. Therefore, the convex portions 14B, 15C, 1 of the joint materials 14, 15, 16
6B is fastened to the outer periphery between the outer frame body 1 and the inner frame body 6 in a clamping manner, so that the strength of the connecting portion between both the frame bodies 1 and 6 can be improved, and the outer frame body 1 Mounting pieces 2J, 3G, 4H, and 5H formed protruding in the outer circumferential direction on the outdoor side of the contact piece 14C,
Can be fixedly supported by 15E and 16C,
Moreover, this makes it possible to strengthen the connection with the frame materials 11, 12, and 13, and to ensure watertightness of the connection portions. In addition, joint material 14,1
Since the convex portions 14B, 15C, and 16B of 5 and 16 also serve as spacers at the connection portion of the frames 1 and 6, both the frames 1 and 6 can be connected accurately, and the connection work is extremely easy. There are many features such as what you can do.

Now, the present invention is a double sash formed by connecting an outer frame body and an inner frame body with a joint material, and the joint material is attached to the back side of both the frame bodies, and between the inner and outer frame bodies. A contact piece is provided that has a convex part to be held and that comes into contact with a mounting piece that protrudes from the outdoor end of the outer frame toward the outer circumference, and at least the contact piece on the indoor side of the joint material, the convex part, and the outdoor side. The structure is such that it is fixedly attached to and connected to both the frames. Therefore, since the convex portion of each joint material is fixed to the outer periphery between the outer frame body and the inner frame body in a clamping manner, it is possible to improve the strength of the connection portion between both frame bodies. , it is possible to fixedly support a mounting piece formed on the outdoor side of the outer frame body so as to protrude toward the outer circumference. In addition, since the convex part of each joint material also serves as a spacer at the connection part between the outer frame and the inner frame, the frames can be connected accurately and the connection work can be performed extremely easily. This is an extremely practical idea as a double satsushi.
