An airtight material s is provided on the outdoor side surface of the indoor side hollow wall 12b, and is airtight between the lower frame 12 and the lower stile 22 of the shoji 2. Further, an expansion material holding groove 12c for holding the heat expansion material or the like is formed on the outdoor side surface of the indoor side hollow wall 12b, and the heat expansion material can be arranged as needed.

Since the left and right vertical frames 13 and 14 have the same configuration, the configuration of the vertical frame will be described below using the right vertical frame 14.
As shown in FIG. 3, the right vertical frame 14 includes a prospect wall 14a fixed to the skeleton opening A and an indoor side finding wall extending in the inner peripheral direction from the inner peripheral surface of the prospect wall 14a near the indoor side. One end 81 of a damper 8 having 14b and urging the shoji 2 of the window to be tilted outward on the inner peripheral surface of the prospect wall 14a in the opening direction is fixed.

An airtight material s is provided on the outdoor side surface of the indoor side finding wall 14b, and is airtight between the right vertical frame 14 and the right stile 24 of the shoji 2.
Further, expansion material holding grooves 14c and 14d for holding the heat expansion material and the like are formed on the inner peripheral surface of the prospect wall 14a near the outdoor side and the outdoor side surface of the indoor side finding wall 14b.

As shown in FIG. 2, the upper stile 21 of the shoji 2 extends upward from the upper stile main body 21a having a hollow portion and a glass frontage 21d on the inner circumference and the outdoor side end of the upper stile main body 21a. The outdoor wall portion 21b is provided, and the shoji side member 63 of the operator 6 is fixed to the indoor side surface of the upper frame main body portion 21a.
The upper end edge of the panel 25 is fitted into the glass frontage 21d via a backup material and a sealing material.

As shown in FIG. 2, the lower stile 22 of the shoji 2 extends downward from the lower stile main body 22a having a hollow portion and a glass frontage 22d on the inner circumference and the outdoor side end of the lower stile main body 22a. The outdoor wall portion 22b is provided, and the shoji side wing 72 of the hinge member 7 is fixed to the lower surface of the lower frame main body portion 22a.

A reinforcing member 92 made of steel, for example, is provided in the hollow portion of the lower frame main body portion 22a. A plurality of setting blocks 221 made of short aluminum members are arranged at appropriate positions of the glass frontage 22d, and the lower end edge of the panel 25 is supported by a cushioning material, and is fitted via a backup material and a sealing material. ing.
Therefore, the load of the panel 25 can be supported by the setting block 221 and the reinforcing member 92.

The right stile 24 is formed from a stile main body 24a having a hollow portion, an outdoor wall portion 24b extending in the outer peripheral direction from the outdoor side end of the stile main body 24a, and an outdoor side end of the stile main body 24a. It has a glass frontage wall portion 24c extending in the inner peripheral direction and a ridge 241 attached to the inner peripheral surface of the vertical frame main body 24a on the indoor side. Is formed.

The other end 82 of the damper 8 is fixed to the outer peripheral surface of the vertical frame main body 24a, and the airtight material s that comes into contact with the vertical frame 14 is arranged at the outer peripheral end of the outdoor wall 24b, and the right vertical frame. The space between 14 and the right stile 24 of the shoji 2 is airtight.

In the above-mentioned outside window of the present embodiment, the operator 6 including the wire 6a that connects the upper frame 11 and the upper stile 21 of the shoji 2 is operated to open and close, so that the vertical stile 24 of the shoji 2 can be found. It is not necessary to provide a handle or the like on the wall, and the found size of the vertical frame 24 of the shoji 2 can be reduced to secure a large lighting area.

Here, in recent years, high fire protection performance is required even for an external window that can be opened and closed by the operator 6. However, as shown in FIG. 4B, the vertical stile 24a of the outside window having a small found size is easily deformed by heat in the event of a fire, and as a result, the panel 25 such as glass is held. There is a possibility that the fire will fall off and spread without being able to do so.

Further, the outside window that can be opened and closed by the operator 6 is loosened due to the operator's wire being stretched or the pulley being melted due to heat, and the closed state of the shoji 2 cannot be maintained, so that the frame 1 and the shoji 2 cannot be maintained. There may be a gap between the and. Therefore, it is preferable to arrange the heat expansion material between each frame material of the frame body 1 and each frame material of the shoji 2.
However, since the outside window opens and closes around the hinge member 7 (rotating shaft) between the lower frame 12 and the lower stile 22, the vertical frames 13 and 14 of the frame 1 and the stile 23 of the shoji 2 The size of the gap formed between the 24 and the upper portion differs between the lower portion and the upper portion, and it is complicated to effectively arrange the heat expansion material.

The external window of the present embodiment can eliminate the disadvantage in fire protection performance while maintaining the advantage of the external window that can be opened and closed by the operator.
Hereinafter, a characteristic configuration for improving the fire protection performance of the outside window of the present embodiment will be described with reference to the right vertical frame 14 and the right vertical stile 24.

Since the right stile 24 of the shoji 2 of the outside window of the present embodiment has a small found size of the stile main body 24a, it is particularly affected by heat between the upper stile 21 and the portion where the lower stile 22 is fixed. Deformation is likely to occur. Therefore, as shown in FIGS. 4A and 5A, the external window of the present embodiment is made of steel or the like in the hollow portion between the upper stile 21 and the lower stile 22 of the vertical stile main body 24a. A long flat plate-shaped reinforcing member 9 made of a metal material is arranged.

The reinforcing member 9 is arranged in contact with the glass frontage side prospective surface in the hollow portion of the vertical stile main body portion 24a, and is fixed from the bottom wall of the glass frontage 24d of the right stile 24 by a fixing means b1 such as a screw. There is.

The reinforcing member 9 has an estimated width dimension that is almost the same as the expected width dimension of the hollow portion of the vertical frame main body portion 24a, and the vertical frame main body portion 24a formed with a small found dimension is deformed by heat. It is possible to prevent the panel 25 such as glass from falling off.

As shown in FIG. 5, a drain hole 24f is formed on the bottom surface of the glass frontage 24d of the vertical stile 24 to guide the water collected in the glass frontage 22d of the lower stile 22 into the hollow portion of the vertical stile main body 24a. By providing the reinforcing member 9 between the portion where the upper stile 21 and the lower stile 22 are fixed, the drain hole 24f is not blocked.

Further, as shown in FIG. 4A, in the vertical frame 14 of the outside window of the present embodiment, the expansion material holding groove 14c is formed on the outdoor side of the prospect wall 14a, that is, the inner peripheral surface on the open side in the prospective direction. The heat expansion material f41 is arranged over at least an upper portion (for example, a range of half from the upper end) of the expansion material holding groove 14c.
Therefore, as shown in FIG. 6A, the wire 6a of the operator 6 loosens in the event of a fire, and the airtight material s of the indoor side finding wall 14b of the vertical frame 14 and the finding surface of the vertical stile 24 are separated from each other. As shown in FIG. 6B, the vertical frame 14 and the vertical stile are expanded by the heat expanding material f41 while maintaining the state of the vertical stile 24 by the reinforcing member 9, even when a gap is formed. It is possible to suppress indoor / outdoor communication with the 24.

As the heat-expanding material that closes between the vertical frame 14 and the vertical frame 24, in addition to the heat-expanding material f41 arranged on the inner peripheral surface of the prospective wall 14a of the vertical frame 14, the indoor side view of the vertical frame 14 The heat expansion material f42 facing the indoor side finding surface of the right stile 24 may be arranged in the expansion material holding groove 14d formed on the outdoor side surface of the attachment wall 14b.

For example, between the vertical frame 14 and the vertical stile 24, as shown in FIG. 7A, the lower portion of the vertical frame 14 having a relatively small gap is located on the outdoor side of the indoor side finding wall 14b. The gap between the vertical frame 14 and the vertical stile 24 is closed by a relatively small amount of the heat-expanding material f42 arranged, and the upper portion of the vertical frame 14 having a relatively large gap (as shown in FIG. 7B) (as shown in FIG. For (a range of half from the upper end), the gap between the vertical frame 14 and the vertical stile 24 may be closed by the heat expansion material f41 arranged on the inner peripheral surface of the prospective wall 14a of the vertical frame 14.

As described above, in the fitting of the present embodiment, by reinforcing the prospective wall of the vertical stile having a small expected size with a reinforcing member, it is possible to prevent the prospective wall from being deformed by heat and maintain the holding of the panel by the stile. can.
Then, by forming the reinforcing member from a plate-shaped member and fixing it to the surface on the glass frontage side in the hollow part of the vertical stile, it can be smoothly inserted into the hollow part of the vertical stile and a screw for fixing. Etc. are hidden in the frontage of the glass, and do not interfere with the installation of devices such as dampers on the outer peripheral side of the stile.

Furthermore, even if the reinforcing member is placed in the hollow part of the vertical stile, the heat expansion material that expands toward the outer peripheral surface of the vertical stile reinforced by the reinforcing member against the looseness of the wire that may still occur in the event of a fire. Is provided on the inner peripheral surface of the vertical frame on the outdoor side, so that the gap between the frame and the shoji can be reliably closed.

At this time, for the lower part where the vertical frame and the vertical stile are relatively small apart, a heat expansion material is provided on the outdoor side of the indoor side finding wall of the vertical frame, and the vertical frame and the vertical stile are compared. By providing a heat-expanding material on the inner peripheral surface of the vertical frame on the outdoor side, the amount of heat-expanding material used can be relatively small, and the gap between the frame and the shoji can be made efficient. Can be closed to.

The structure of the fitting of the present invention is not limited to the outside window of the above embodiment.
For example, the operator who opens and closes the window may be a type of operator installed between the upper frame and the upper stile.

Further, it goes without saying that the heat-expanding material may be arranged as necessary in the expansion material holding groove formed in the upper frame 11 or the lower frame 12 of the outside window of the present embodiment.
Further, each heat-expanding material may be attached to the frame material or the frame material by a double-sided adhesive tape or the like instead of being held by the expansion material holding groove.

Further, the reinforcing member arranged in the hollow portion of the vertical stile of the shoji is preferably provided over the entire width of the prospective surface of the stile, but the hollow portion and the reinforcing member require a play portion for manufacturing. Therefore, the expected width dimension of the reinforcing member may have a width dimension of at least 80% or more (almost the entire width) of the expected surface of the vertical stile.
Further, if the reinforcing member is arranged in the hollow portion of the vertical stile and has a portion that abuts over almost the entire width of the prospective surface of the vertical stile, it is viewed from one side or both sides of the flat plate in the longitudinal direction. It may have a substantially U-shaped or L-shaped cross section having an attached wall.

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