(Structure of window)
The window portion 2 of the fire protection fitting of the present embodiment has fire resistance, and as shown in FIG. 2, the vertical frame 23 on the connecting material side is fixed to the frame mounting material 12, and the anti-connecting material side (frame opening). The vertical frame 24 (on the side A) is attached to the skeleton opening A by being fixed to the anchor member 5 fixed to the skeleton opening A.
As shown in FIG. 4A, the vertical frame 23 (24) of the window portion 2 fixed to the connecting member 1 (and the anchor member 5) has at least the prospective wall 23a and the outer periphery from the indoor end of the prospective wall 23a. The indoor side mounting piece 23b extending toward the side and having the tip bent in the outdoor direction, the hollow portion 23c provided on the outdoor outer peripheral surface of the prospective wall 23a, and the indoor side end on the inner peripheral side of the hollow portion 23c. It has an outdoor mounting piece 23d extending from the window toward the room and further bent toward the outer peripheral side.

Then, the vertical frame 23 is fixed by the fixing means b8 such as a screw or the like so that the indoor side mounting piece 23b abuts on the indoor side mounting portion 12b of the frame mounting material 12 so as to overlap in the prospective direction from the outdoor side. The found wall of the outdoor mounting piece 23d is in contact with the outdoor mounting portion 12e of the frame mounting material 12 so as to overlap in the prospective direction from the indoor side, and is fixed by fixing means b9 such as a screw.

It is the outdoor side of the outdoor mounting pieces 23d and 23d of the vertical frame 23 fixed to the outdoor mounting portion 12e of the frame mounting material 12, and the sealing material is between the hollow portions 23c and 23c of the vertical frames 23 and 23. s is provided, and the space between the vertical frames 23 and 23 is airtight.
The outdoor side of the connecting member 1 of the fire protection fitting is formed flush with each other without arranging a member protruding from the outdoor surface of the vertical frames 23, 23 to the outdoor side.

As described above, in the fire protection fitting of the present embodiment, the connecting material main body 11 of the connecting material 1 that supports the window portion 2 is set to have a small dimension in the finding direction in order to secure the area of the opening. The dimensions in the prospective direction are set small so that the work can be performed flush with each other without providing a protrusion on the outdoor surface.
Therefore, it is difficult to secure a sufficient cross-sectional area of the connecting material main body 11 supported by the anchor member 5 in the skeleton opening A, and it is difficult to maintain the strength. In particular, the strength of fittings with a large opening height was often insufficient.

On the other hand, in the fire protection fitting of the present embodiment, the connecting material 1 is provided by arranging the reinforcing member 134 for reinforcing the connecting material 1 further on the indoor side of the fire resistant member 132 arranged on the indoor side of the connecting material main body 11. It is an improved strength of.

Specifically, a hollow portion 133b in which the reinforcing member 134 can be arranged is formed in the indoor side cover member 133 that covers the fireproof member 132, the reinforcing member 134 is arranged in the hollow portion 133b, and the reinforcing member 134 is provided. The strength of the indoor side cover member 133 is increased by fixing it in the hollow portion 133b of the indoor side cover member 133 by a fixing means b7 such as a screw.
Then, the indoor side cover member 133 having improved strength is fixed to the locking piece 131b of the connecting member 131 fixed to the connecting material main body 11 by a fixing means b6 such as a screw, whereby the connecting material main body 11 and the chamber are fixed. The connecting material 1 having high strength is configured by integrating the inner cover member 133.

In the fireproof fitting of the above embodiment, the fireproof member 132 is arranged on the indoor side of the connecting material main body 11 constituting the connecting material 1, and the reinforcing member 134 is arranged on the indoor side of the fireproof member 132. The strength of the connecting material 1 as a whole can be improved.
Therefore, the found size of the connecting material 1 can be reduced, and the opening portion can be kept wide. Further, it is possible to form the expected dimension of the connecting member 1 smaller than the expected dimension of the window portion, and the outdoor side of the window can be formed flush with each other.

Then, the reinforcing member 134 for increasing the strength of the entire connecting material 1 is fixed to the indoor side cover member 133 constituting the connecting material 1, and the indoor side cover member 133 is fixed to the connecting material main body 11. Since it is reinforced by fixing it to 131, if the height dimension of the opening is small, the indoor cover member 133 may be changed to an indoor cover member that does not have a hollow portion, or the reinforcing member 134 may be inside the hollow portion. It is possible to easily set the reinforcement according to the fitting without changing the configuration of the connecting material main body 11 by not arranging the connecting member main body 11.

In the present embodiment, the reinforcing member 134 arranged on the indoor side of the refractory member is fixed to the outdoor wall in the hollow portion of the indoor side cover member 133, but the fixing of the reinforcing member 134 is limited to the above configuration. It may be fixed to any member as long as the connecting member 1 can be reinforced.

Needless to say, the above embodiments do not limit the invention described in the claims, and are treated as examples.
