d, the joining piece 7c approaches the inner peripheral end or the outer peripheral end of the vertical member inner peripheral piece 37, and the contact piece 7a is circumscribed on the outside of the vertical frame material chamber outer wall 3b. Then, the inner step piece 7b cuts into the indoor side on the outer periphery of the vertical member 3 to enable the fixed piece 34 of the vertical member 3 to abut.

Since the sash exterior frame of the present invention has the above-described structure, the frame body 10 is assembled in advance with the upper member 1 and the lower member 2 and the vertical members 3 and 4, while the inner step piece 6b of the upper fixing member 6 is assembled. The abutting piece 6a is circumscribed to the outdoor wall 1b of the upper frame member F1 of the existing sash frame F with the joining piece 6c facing the outside and the joining piece 6c is directed to the outside, and is screwed to the inner wall of the vertical fixing member 7. The piece 7b is also directed indoors, and the joining piece 7c is directed outdoors, so that the contact piece 7a is circumscribed to the outdoor wall 3b of the vertical frame member F3, and is screwed. At this time, the joining pieces 6c and 7c are
The inner peripheral pieces 17 and 37 are attached so as to approach the inner peripheral tip or the outer peripheral tip.

When attaching the sash exterior frame of the present invention to the opening H, first, a sash frame F having the fixing members 6, 7, 8 attached thereto is inserted into the opening H, and the fixing bracket is adjusted while adjusting the sash frame F in and out. 9 and is fixed to the lip groove material D. For example, the inward projecting pieces f1 and f of the upper frame material F1 and the vertical frame materials F3 and F4.
3 and f4, two fittings 9 are fitted respectively, and two fittings 9 are fitted into the inwardly projecting piece f2 of the lower frame member F2. Each of the fittings 9 is a lip groove member D forming an opening H. And welded to each.

Next, when the frame body 10 is pulled from the outside of the opening H toward the sash frame F attached earlier, the inner peripheral pieces 17, 37 of the upper member 1 and the vertical member 3 are cantilevered. In state,
Moreover, fixing members 6, 7 attached to the upper frame member F1 and the vertical frame member F3.
Since the joining pieces 6c and 7c protrude so as to approach the outer peripheral end portions of the inner peripheral pieces 17 and 37, the engaging pieces 18 and 38 of the inner peripheral pieces 17 and 37 are pulled by the frame body 10 being pulled. Are engaged with each other over the locked pieces 6d, 7d of the joining pieces 6c, 7c. At this time, the fixing piece 14 of the upper member 1 circumscribes the inner step 6b of the upper fixing member 6, the fixing piece 34 of the vertical member 3 circumscribes the inner step 7b of the vertical fixing member 7, and the lower member 2 Indoor piece 22
Circumscribes the mounting wall 2d of the lower frame member F2. After the frame body 10 is locked to the fixing member 6, the fixing piece 14 and the inner step piece 6 to be joined are joined.
b, the fixing piece 34 and the inner step piece 7b are screwed together, and the indoor piece 22 and the mounting wall 2d are screwed together.
Is strongly fixed.

As a means for locking the upper member 1 and the upper fixing member 6, for example, a locking piece 18 of the inner member 17 of the upper member may be used.
7, an outward-facing hook that is folded outward to the outside on the outer peripheral side, and the locked piece 6 d of the upper fixing member 6 is a room-facing hook that is folded toward the interior on the inner peripheral side, opposite to the locking piece 18. So that they can be locked together. As means for locking the vertical member 3 and the vertical fixing member 7,
Similarly to the above-mentioned locking means, the locking piece 38 of the vertical member inner peripheral piece 37
Is formed into an outdoor-facing hook shape that is folded outward on the outer peripheral side of the inner peripheral piece 37, and the locked piece 7 d of the vertical fixing member 7 is folded toward the indoor side on the inner peripheral side opposite to the locking piece 38. The hook should be indoor-facing.

The procedure for mounting the exterior frame of the present invention is not limited to the above example. For example, after the sash frame F is mounted on the indoor side of the frame opening H, the upper fixing material 6 is mounted on the outside of the upper frame material F1. It is also possible to attach the vertical fixing member 7 to the outdoor side of the vertical frame member F3 and lock the frame body 10 to this. The upper and lower members 1 and 2 and the vertical member 3 that constitute the frame body 10
4, and the fixing members 6, 7, and 8 attached to the sash frame F are formed by extruding from light metal similarly to the upper and lower frame members F1, F2 and the vertical frame members F3, F4 of the sash frame F. It can be changed as appropriate without departing from the gist of the present invention.

[0018]

[Effects of the Invention] Since the exterior frame for a sash of the present invention is configured as described above, the following effects can be obtained. The frame body is provided with a connection portion corresponding to the thin upper portion of the exterior material upper portion on the upper member, the indoor piece circumscribing the mounting wall of the lower frame material on the inclined piece of the lower member, and Equivalent water slices,
Since the legs corresponding to the ridges at the lower part of the exterior material are provided, the exterior materials mounted on the upper and lower sides of the frame body can be easily and easily attached by the same means as the exterior material connected to the skeleton.

Since the exterior frame of the present invention is constructed by dividing the frame body and the fixing member attached to the outdoor side of the sash frame, the structure is simple, the frame body can be easily assembled, and the frame body can be easily mounted. Also, in the above, the locking piece is provided on the inner peripheral piece of the upper member and the vertical member of the frame body, and the locked piece is provided on the fixing member, so that the frame body is moved from the outdoor side to the sash frame. , The frame body can be locked to the fixing member. Moreover, with the frame body in the locked state, the indoor piece of the lower member is attached to the mounting wall of the lower frame material,
Since the fixing piece of the upper member and the vertical member can be fixed with screws to the inner step of the fixing material, the fixing with screws can be performed in a stable state. In addition, the exterior frame of the present invention can be attached to the existing opening when the exterior of the building is renewed or changed, and the appearance of the window mounting part can be improved by attaching the exterior frame of the present invention to the opening. Also, the waterproof effect of the window mounting part is improved.
