Regarding each configuration of the lower frame 12, a corresponding symbol is attached to a configuration symmetrical to the upper frame 11 shown in FIG. 5, and the description thereof is omitted.

Next, the installation method of the above fire prevention panel 1 and the operation and function of the fire prevention panel 1 in the event of a fire will be described.
When installing the fire protection panel 1, as shown in FIG. 3, the back plate 5B is arranged from the inside of the back portion 7 of the vertical frame 5 to the space between the back portions 7 and fixed. Similarly, as shown in FIGS. 5 and 7, back plates 11B and 12B are also arranged between the back portions 7 and 7 of the frame body 11A of the upper frame 11 and the frame body 12A of the lower frame 12 and fixed from inside. I do.

Next, the vertical frame 5 to which the back plate 5B is fixed is installed and fixed to a side wall surface or an opening formed in the side wall in the room where the fire protection panel 1 is installed.
The frame main body 11A of the upper frame 11 to which the back plate 11B is fixed is fixed to the upper part of the vertical frame 5 above the opening formed in the ceiling surface or the side wall.

The frame main body 12A of the lower frame 12 to which the back plate 12B is fixed is arranged and fixed to a lower portion of an opening formed on a floor surface or a side wall between lower portions of the vertical frame 5, respectively.
At this time, the frame main body 11A of the upper frame 11 and the frame main body 12A of the lower frame 12 are fixed in the room such that the auxiliary ridges 14 are arranged near the side where the glass panel 2 is fitted.

A setting block (not shown) formed in a rectangular parallelepiped shape is arranged on the groove bottom surface 6b of the fitting groove 6 of the frame main body 12A of the lower frame 12.
The lower end of the glass panel 2 is placed on a setting block (not shown) of the frame main body 12A of the lower frame 12, and the upper end of the glass panel 2 is disposed in the fitting groove 6 of the frame main body 11A of the upper frame 11. One side end of the glass panel 2 is fitted into the fitting groove 6 of the vertical frame 5 as much as possible.

  Thereby, the glass panel 2 is housed in the opening surrounded by both the vertical frames 5 and 5, the frame body 11A of the upper frame 11, and the frame body 12A of the lower frame 12, and the other side end of the glass panel 2 is The opposite vertical frame 5 can be fitted into the fitting groove 6 of the other vertical frame 5. In this state, the position is adjusted in the horizontal direction so that the left and right side ends of the glass panel 2 fit into both of the fitting grooves 6 of the opposed vertical frame 5.

An auxiliary ridge 14 is installed on each of the upper frame 11 and the lower frame 12, and a fixing tool (not shown) is inserted from the opening 20 to attach the auxiliary ridge 14 to each of the upper frame 11 and the lower frame 12. It is fixed to the side of the fitting groove 6. A caulking material or the like is appropriately disposed between the glass panel 2 and the inner surface 6a of the fitting groove 6.
In this state, in the fitting grooves 6 of the vertical frames 5, 5 and the upper frame 11, a gap is formed in which the distance from the end surface of the glass panel 2 to the groove bottom surface 6b is about 2 mm to 20 mm or about 5 mm to 16 mm. Have been.

When the vertical frame 5, the upper frame 11, and the lower frame 12 are installed as described above, the space between the fitting groove 6 of the vertical frame 5 and the fitting groove 6 of the upper frame 11 and the position of the fitting groove 6 of the vertical frame 5 are lower. No member such as a blocking member is provided between the frame 12 and the fitting groove 6. Therefore, all spaces formed by the fitting groove 6 and the end of the glass panel 2 communicate with each other.
As described above, the installation of the fire prevention panel 1 in the room or the opening formed in the wall of the room is completed.

  When a fire occurs in the room where the fire prevention panel 1 is installed, the temperature of the glass panel 2 rises, the resin sheet 4 of the intermediate layer is melted, and gas may be generated from the resin sheet 4. When gas is generated from the resin sheet 4, the gas accumulates in the fitting grooves 6 of the vertical frame 5, the upper frame 11, and / or the lower frame 12 from the end surface of the glass panel 2.

  When the glass panel 2 is fitted into the fitting groove 6, the conventional fire-resistant glass with a frame in which the inside of the fitting groove 6 is substantially sealed is filled with gas in the fitting groove 6. There is a possibility that the gas leaks out from a slight gap formed between the groove 6 and the glass panel 2 and emits an unusual odor or causes a fire.

  However, according to the fire prevention panel 1 of the present invention, since the exhaust holes 10 are formed in the groove bottom surfaces 6 b of the fitting grooves 6 of the vertical frame 5, the upper frame 11, and the lower frame 12, the fire holes are generated from the resin sheet 4. The gas can be kept inside the fitting groove 6 and on the back side of the vertical frame 5, the upper frame 11 and the lower frame 12 without leaking the gas to the interior or the exterior where the fire is present.

  Therefore, when a fire occurs around the fire prevention panel 1, it is possible to effectively prevent the gas generated from the resin sheet 4 from emitting an odor or igniting the gas. That is, since the glass panel 2 has the resin sheet 4, the fire prevention panel 1 has an effect of improving impact resistance and improving fire prevention performance.

  The space between the fitting groove 6 of the vertical frame 5 and the glass panel 2, the space between the fitting groove 6 of the upper frame 11 and the glass panel 2, and the fitting groove 6 of the lower frame 12 and the glass panel 2. Since the spaces between them are connected to each other, there is room in the space for storing gas. That is, even when the fire panel 1 is locally heated and a large amount of gas is generated from one side of the vertical frame 5 of the glass panel 2, for example, the gas spread in the fitting groove 6 of the vertical frame 5 is not removed. It flows into the fitting groove 6 of the adjacent upper frame 11 or lower frame 12. Therefore, there is an effect that the capacity for storing gas in each part of the frame member 3 is increased, so that the gas can be more effectively prevented from being filled.

  Further, since the fire prevention panel 1 has a gap between the groove bottom surface 6b and the end face of the glass panel 2, when the glass panel 2 is inclined with respect to the frame member 3 due to the occurrence of an earthquake or the like, the glass panel 2 Of the frame member 3 can be absorbed to some extent to avoid contact. Therefore, the fire prevention panel 1 has an effect that breakage of the glass panel 2 due to contact between the groove bottom surface 6b and the glass panel 2 or the like can be effectively prevented.

  In the above-described embodiment, an example of the shapes of the vertical frame 5, the upper frame 11, and the lower frame 12 has been described. However, the present invention is not limited to the frame member 3 having the shape of the above-described embodiment. Absent. That is, the present invention is applied to a frame member in which each of the vertical frame 5, the upper frame 11, and the lower frame 12 is hollow and in which the fitting groove 6 for fitting the glass panel 2 is formed, for example, as shown in FIG. As shown in the vertical frame shown in FIG. 8 or the lower frame shown in FIG.

  Further, the example in which the exhaust holes 10 are formed in the fitting grooves 6 and 6 of the vertical frames 5 and 5, the fitting grooves 6 of the upper frame 11, and the fitting grooves 6 of the lower frame 12 has been shown. Is formed in any one of the fitting grooves 6 of the vertical frame 5, the upper frame 11, and the lower frame 12, the effect of the present invention can be attained at all. Further, since the fire prevention panel 1 has a gap between the end face of the glass panel 2 and the groove bottom surface 6b, even if the discharge hole 10 is not formed, a certain amount of gas is stored in the event of a fire and the gas becomes glass. This has the effect of preventing seepage on the panel 2 side.

Further, the exhaust hole 10 may be formed on the inner side surface 6a side of the fitting groove 6 as long as it is not covered by the glass panel 2.
Further, a part of the fitting groove 6 of the vertical frame 5, the upper frame 11, or the lower frame 12 may be communicated.

  Further, the frame member may not be integrally formed. For example, as shown in FIGS. 9 (a) and 9 (b), the auxiliary ridge 14 shown in FIG. The vertical frame 5 shown in FIG. 3 may be formed by combining two members, as shown in FIG.

Further, as shown in FIGS. 11 and 12, the width of the fitting groove 6 of the vertical frame 5, the upper frame 11 and / or the lower frame 12 is set to be smaller than the groove bottom in the depth direction of the opening 6t. The 6b side may be widened.
According to this configuration, there is an effect that a larger space for storing gas can be obtained than in a case where the groove width of the fitting groove 6 is formed straight in the depth direction.
