It is set to be smaller than the dimension between the portion 18 and the portion 18.

Next, a method of installing the fitting frame X and the glass panel G, their actions and functions will be described.
First, the trocover 1A is attached to the frame body 11A of the lower frame 11. The trocover 1A is arranged on the back surface side of the front surface portion 16 of the frame main body 11A so as to surround the insertion hole 16h by the flange 3A.
At this time, since the magnet plate 4 is laminated on the flange 3A of the trocover 1A, it is made of a steel plate if there is a space for the trocover 1A even in a place where it was conventionally difficult to attach the trocover 1A by welding. It can be easily fixed to the frame body 11A.

Further, in the conventional mounting by welding, it is difficult to weld depending on the part, or the strength is partially varied by welding. In addition, welding installation takes time for welding work and finishing. However, since the magnet plate 4 is provided on the entire upper surface of the flange 3A, the trocover 1A can be fixed to the lower frame 11 with substantially equal strength, and can be fixed to the lower frame 11 in an extremely short time. It plays the effect.
The toro cover 1A is attached to the frame body of the upper frame 12 in the same manner as the frame body of the lower frame 11.

Then, the frame main bodies 11A and the like of the lower frame 11, the upper frame 12, and the vertical frame 13 are fixed to the openings and the like of the wall on which the glass panel G is installed. After arranging the glass panel G at a position to be the fitting groove 21 of the frame main body 11A, 12A, 13A, the auxiliary ridge portion 14 is attached in parallel to the ridge portion 15 to sandwich the glass panel G, and the fixture 20 is attached. The auxiliary ridge portion 14 is inserted and fixed to the frame main body 11A.

When the fixture 20 is inserted through the auxiliary ridge portion 14 and the frame body 11A, the tip of the fixture 20 penetrates the front surface portion 16 of the frame body 11A and projects toward the back surface portion 18. The portion where the fixture 20 protrudes and the space around the fixture 20 are covered with the trocover 1A. Further, in the Trocover 1A, the flange is in close contact with the back surface side of the front surface portion 16.

After the fitting frame X to which the trocover 1A is attached to the lower frame 11 and the upper frame 12 is applied to the building of the RC skeleton, as shown in FIG. 5, the gap between the fitting frame X and the RC skeleton is filled with the mortar 50. And finish it. At this time, the mortar 50 is also filled in the fitting frame X, but since the fixture 20 is covered with the trocover 1A, the mortar 50 is prevented from entering the space covered by the trocover 1A, and screws and the like are prevented. It is possible to prevent the fixture 20 from being buried in the mortar 50.
As a result, when the glass panel G is to be removed after the fitting frame X is installed in the building, the fixing tool 20 such as the screw of the auxiliary ridge portion 14 can be easily removed, and the auxiliary ridge portion 14 can be easily removed from the frame body. It has the effect of being able to be removed.

In this case, as shown in FIG. 6, it is preferable that the flange 3A is provided with two protrusions 5 in the longitudinal direction 3b of the sides facing each other, for a total of four protrusions 5 at intervals. The protrusion 5 is formed so as to have a thickness equivalent to that of the adhesive to be provided and a protrusion of several mm or less. The adhesive is applied to a portion of the flange 3A other than the protrusion 5.

In the toro cover 1A of such a modification, the toro cover 1A can be fixed to the frame body 11A only by pressing the flange 3A against the back surface side of the front surface portion 16 of the frame body 11A, so that the toro cover 1A can be attached very easily. The effect of becoming is obtained. The protrusion 5 of the flange 3A comes into contact with the back surface of the frame member 10, and a gap is formed between the back surface of the frame member 10 and the flange 3A. Since the adhesive layer can be made thicker by the amount of this gap, the adhesive strength between the trocover 1A and the frame member 10 can be increased.

The number and arrangement of the protrusions 5 are not particularly limited, but it is preferable that two or more protrusions 5 are provided symmetrically. When the protrusions 5 are provided symmetrically, the installation of the trocover 1A is stable and it becomes easy to form the adhesive layer evenly.
The adhesive may be a liquid, an adhesive tape such as a double-sided tape, an adhesive, or a combination thereof. Further, the sticking means may be a combination of the adhesive and a magnet.
