The panel frontage 34a holds the panel body 35 via a glazing channel 349 made of resin material or the like.

The overall configuration of the double sliding sash of the present embodiment has been described above. Further, the configuration of the lower frame of the shoji 30 will be described using the lower frame 32 of the outer shoji 30 .

The lower frame 32 is formed of an extruded aluminum profile or the like, and as shown in FIGS. It is an elongated member having a substantially H-shaped cross section and a bottom wall 32e.
The lower frame 32 has a panel opening 32a for holding the panel body 35 on the inner peripheral (upper) side of the bottom wall 32e, and an opening groove 32b for accommodating the door roller 9 on the outer peripheral (lower) side.

The lower frame 32 is formed with a plurality of discharge holes 32f, 32f for discharging water that has entered the panel frontage 32a near both ends in the longitudinal direction of a bottom wall 32e that forms the bottom of the panel frontage 32a. A tapping hole 32g is formed in the upper surface of the wall 32e. In addition, the lower frame 32 has a thermally expandable fire-resistant material f3 that is foamed by heat disposed on the exterior side of the interior side wall 32c.

At the panel frontage 32a of the lower rail 32, a glass floor plate 50 for supporting the panel body 35 and a detachment prevention member 60 for preventing the panel body 35 from falling off the lower rail 32 in case of fire are arranged. .

The glass floor plate 50 is a piece member made of a synthetic resin material or the like, and as shown in FIG. It has parts 50b, 50b.

Then, as shown in FIGS. 4B and 5A, the glass floor plate 50 has two leg portions 50b, 50b so as to straddle the tapping hole 32g formed in the bottom wall 32e of the panel frontage 32a. is arranged at an appropriate position of the panel frontage 32a.

As shown in FIG. 5(c), the retaining member 60 is a short member formed by cutting and bending a metal material such as steel. Detachment prevention portion 60b formed by bending both ends of the central portion in the longitudinal direction upward, leg portions 60c formed by bending both ends of both ends in the length direction of the panel mounting surface 60a downward, and the panel mounting surface. The center portion of 6a has a mounting portion 60d formed by cutting and bending so as to protrude downward, and a screw hole 60e is formed in the center of the mounting portion 60d.
It should be noted that the retaining member 60 may be provided with a cushioning member such as a heated foam material on the surface of the retaining portion 60b facing the panel body 30. As shown in FIG.

4(a) and 5(a), the retaining member 60 taps the mounting portion 60d in the central portion of the panel mounting surface 60a to the bottom wall 32e of the panel frontage 32a. It is fixed to the lower frame 32 by fixing means such as screws while being placed on the upper surface of the hole 32g.
In the fittings of this embodiment, the detent members 60 are attached to positions near both longitudinal ends of the lower frame 32 , and the glass floor plate 50 is arranged inside the detent members 60 .

As shown in FIG. 4(a), the detent member 60 fixed to the lower frame 32 is configured such that the legs 60c, 60c do not contact the upper surface of the bottom wall 32e of the panel frontage 32a, and thus the upper surface of the bottom wall 32e is removed. is maintained at a distance from
Further, as shown in FIG. 4C, the upper surface height of the panel mounting surface 60a of the detent member 60 arranged on the lower frame 32 is set lower than the upper surface height of the support surface 50a of the glass floor plate 50. ing.

As described above, in the fireproof sash of the above embodiment, short detachment prevention members having a panel mounting surface with a predetermined height are arranged in the panel openings at both ends in the longitudinal direction of the lower frame. When the resin member of the stile material melts in the event of a fire and the panel body of the shoji falls, the lower surfaces of both ends of the panel body are placed on a panel mounting surface having a predetermined height to prevent further falling. Therefore, it is possible to prevent the upper part of the panel body from coming off from the upper frame or the like.

Since the retaining member has a retaining portion that restricts the movement of the panel body in the prospective direction, it is possible to prevent the panel body from falling and also to prevent the panel body from coming off in the indoor and outdoor directions.
That is, the retaining member of the present embodiment has two functions: one function is to prevent the panel body from falling downward in the event of a fire, and the other is the function to prevent the panel body from detaching due to displacement in the projected direction. .

In the retainer member of the present embodiment, since the panel mounting surface is separated from the bottom wall of the panel frontage by the legs, the drain hole for draining water in the panel frontage is not blocked.
In addition, in the fireproof sash of the present embodiment, the glass floor plate is arranged together with the retaining member, and the height position of the glass supporting surface of the glass floor plate is set higher than the height position of the panel mounting surface of the retaining member. Therefore, normally, the panel body is supported by the glass floor plate, and the squeak noise generated by the contact between the retaining member and the lower frame due to the load of the panel body being applied to the retaining member can be suppressed. can be done.

In addition, since the legs 60c, 60c of the detent member are not in contact with the top surface of the bottom wall 32e of the panel frontage 32a and are separated from the top surface of the bottom wall 32e, they are usually removed by tapping holes. The one-point support makes it easy to absorb manufacturing errors, etc., and if the panel body falls and is placed on the panel mounting surface in the event of a fire, the leg will contact the bottom wall of the panel frontage due to the load. Since the load of the panel body is supported by two or three points, the panel body can be stably supported.

In addition, since the retaining members are formed of short members arranged at both ends of the lower rail in the longitudinal direction, workability is improved and it is economically preferable.

As described above, the present embodiment has been described using a sliding window, but the configuration of the sash is not limited at all, such as a double-hung window or a FIX window.

In addition, in this embodiment, the two detent members 60, 60 are arranged near both ends of the lower frame 32, and the two glass floor plates 50, 50 are closer to the center than the detent members 60, 60. However, the arrangement position of the glass floor plate 50 is not limited to this example.
For example, one glass floor plate 50 may be arranged at the central position in the viewing direction of the panel frontage 32a of the lower frame 32, and the number and position to be arranged may be appropriately set according to the length of the lower frame 32 and the like.

Moreover, the retaining member 60 is not limited to a member formed by cutting and bending a metal material such as steel. For example, it may be formed by extruding an aluminum alloy, and its manufacturing method is not limited at all.

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