(Construction method when connecting windows 2 and 3 with vertical material 1)
The construction method for connecting the left and right windows 2 and 3 of the fitting of the present embodiment will be described with reference to FIG.
1. 1. A connecting member 61 on one side (right side) of the vertical member 1 is fixed in advance by welding or the like. Further, the left and right windows 2 and 3 are formed by arranging the panel bodies 25 and 35 on the inner circumference of the window frame assembled on the four circumferences.
Then, the vertical member 1 is fixed to the vertical frame 23 of the window 2 via the connecting member 61 and the frame mounting member 62.

The window 2 to which the vertical member 1 is fixed is arranged at a predetermined position in the skeleton opening A, and the upper and lower portions of the vertical member 1 are screwed and fixed to the vertical member mounting members 5 and 5 fixed to the skeleton opening A. By doing so, the window 2 to which the vertical member 1 is fixed is fixed to the skeleton opening.
Instead of fixing the vertical member 1 to the window 2 in advance, the vertical member 1 may be fixed to the skeleton opening A, and then the window 2 may be fixed to the vertical member 1.

2. Next, the vertical frame 34 of the left window 3 to which the connecting member 61 on the other side is fixed is attached to the vertical member 1 fixed to the skeleton opening A.
Specifically, the connecting member 61 on the other side fixed to the vertical frame 34 of the window 3 is placed in contact with the vertical member 1 from the screw insertion hole 12a formed in the indoor side finding wall of the vertical member 1. The vertical frame 34 of the window 3 is fixed to the vertical material 1 by fixing the finding wall 61b of the connecting member 61 to the outdoor side finding wall of the vertical material 1 by a fixing means b1 such as a screw.

When the windows 2 and 3 are fixed on both the left and right sides of the vertical member 1, the upper frames 21, 31 and lower frames 22, 32 of the windows 2 and 3 and the panels of the left and right vertical frames 23, 24, 33, 34 are used. The frontage portion is arranged on the outdoor side of the vertical member 1. Then, the indoor side prospective walls 234 and 334 of both vertical frames 23 and 34 cover the prospective surface of the vertical member 1, and the refractory board mounting portions 234a and 344a of the indoor side prospective walls 234 and 334 are more open than the vertical member 1. It will be located inside.

3. 3. The refractory board mounting plate material 72 is fixed to the refractory board mounting portions 234a and 344a located on the indoor side of the vertical material 1 by a fixing means b2 such as a screw. The refractory board mounting plate material 72 is a rectangular plate-shaped member, and is fixed to the refractory board mounting portions 234a and 344a of the vertical frames 23 and 34 so that the refractory board is placed in contact with the indoor side of the vertical material 1. Can form a flat portion for.

4. Next, the refractory board 71 is arranged on the indoor side of the refractory board mounting plate member 72, and the refractory board 71 is fixed to the vertical member 1 by a fixing means b3 such as a long screw. The refractory board 71 has a long block shape with a rectangular cross section, and has a length dimension such that the upper and lower end surfaces of the refractory board 71 fixed to the indoor side of the vertical member 1 abut on the inner peripheral surface of the skeleton opening A. Have.

In the fitting of the present embodiment, the vertical member attachment members 5 and 5 for fixing the vertical member 1 to the skeleton opening A are provided with holding arm portions 5a and 5a for holding the refractory board 71. By holding the upper and lower portions of the refractory board 71 with the holding arm portions 5a and 5a, it is possible to prevent the refractory board 71 from warping or coming off.

5. After that, on the indoor side of the vertical member 1 and the vertical frames 23 and 34, a cover member 8 is arranged so as to cover the indoor side prospective walls 234 and 344 of the left and right vertical frames 23 and 34, the refractory board 71 and the like, and the cover member 8 is arranged. The outdoor side ends of the left and right prospective walls 8b and 8b of 8 are fixed to the cover member mounting portions 235 and 345 provided on the vertical frames 23 and 34 by fixing means b4 such as screws.
Further, the space between the outer peripheral wall portions 231 and 341 of the left and right vertical frames 23 and 34 is appropriately sealed with a backup material, a sealing material, or the like.
The above is an example of the construction procedure.

(Effect of embodiment)
As described above, in the fitting of the present embodiment, the vertical frames 23 and 34 of the left and right windows 2 and 3 are fixed to the prospective surface of the connecting member 61 fixed to the vertical member 1 at the outdoor side position of the vertical member 1. There is. That is, since the vertical member 1 and the vertical frames 23 and 34 of the windows 2 and 3 are connected on the outdoor side of the vertical member 1 having a hollow shape, it is necessary to connect the windows 2 and 3 on both sides in the prospective direction of the vertical member 1. It is possible to suppress an increase in the expected width of the connecting portion of the windows 2 and 3 in the left-right direction.

By covering the prospective surface of the vertical material 1 made of steel with the indoor side prospective walls of the vertical frames 23 and 34, the vertical material 1 can be prevented from being exposed, the vertical material 1 made of steel can be protected, and the design can be improved. It is good.
Further, by forming the vertical material 1 from a steel material and arranging a fireproof board on the indoor side of the vertical material 1, it is possible to form a connecting portion having excellent fire resistance.
Further, by forming the indoor side prospective walls 234 and 344 of the vertical frames 23 and 34 separately from the outer peripheral wall portions 231 and the like of the vertical frames 23 and 34, the window frame does not need to be the indoor side prospective walls 234 and 344. It can also be used for windows other than continuous windows, improving versatility and simplifying member management. Further, the difficulty level of extrusion molding can be lowered, and the molding accuracy can be improved.

(Other embodiments)
The configuration of the vertical material and the vertical frame of the present invention is not limited to the vertical material and the vertical frame of the above-described embodiment.
For example, as shown in FIG. 4B, the indoor side prospective wall 234 of the vertical frame 23 is integrally formed with the outer peripheral wall portion 231 and the cover member mounting member G is fixed with screws or the like to form the cover member mounting portion 235. You may do so.
By integrally forming the indoor side prospective wall 234, the mounting process of the indoor side prospective wall 234 and 344 can be eliminated, and the manufacturing process can be reduced.

It goes without saying that the above embodiments do not limit the invention described in the claims and are treated as examples.
