JP-A-9-41831

As in Patent Document 1, conventional fireproof panels and the like have a structure in which the caulking groove is closed when the glass panel is fitted into the caulking groove. There was no escape route for the gases from the burning resin in the fire. Therefore, when the caulking groove is filled with gas from burning resin, there is a concern that the gas may seep out from the gap between the upper frame or the vertical frame and leak into the room.
Therefore, the present invention can prevent the gas from seeping into the room when gas is generated from the resin sheet of the fireproof panel installed by fitting the glass panel with the resin sheet interposed in the intermediate layer. Provide fire protection panels.

The fireproof panel of the present invention comprises a glass panel sandwiching a resin sheet, and a frame member having a fitting groove for fitting the end of the glass panel. A gap is formed between the matching groove and the bottom surface of the groove.
According to this configuration, when the resin sheet is heated by a fire and gas is generated, the gas can be stored in the fitting groove as much as possible to prevent the gas from leaking out to the glass panel side.

The frame member of the fireproof panel of the present invention includes a vertical frame formed with fitting grooves for fitting both side ends of the glass panel, and an upper frame formed with fitting grooves for fitting the upper end of the glass panel. and a lower frame formed with a fitting groove for fitting the lower end of the glass panel, wherein the gap between the end surface of the glass panel and the bottom surface of the groove of the vertical frame is the glass panel. It may be formed to be larger than the gap between the end surface and the bottom surface of the groove of the upper frame or the lower frame.
According to this configuration, the gas that is generated by heating the resin sheet by fire and tends to flow upward or downward is guided to the fitting groove of the vertical frame as much as possible, and the back side of the vertical frame (that is, the glass panel) is guided from the fitting groove of the vertical frame. The discharge can be led to the wall side of the building where the frame member is fitted, which is the side opposite to the surface where the frame member is fitted.

The width of the groove bottom surface side may be wider than the opening side of the fitting groove.
According to this configuration, it is possible to expand the space for accumulating the gas generated by the resin sheet being heated by the fire.

Either or both of the fitting groove of the vertical frame and the fitting groove of the upper frame and the fitting groove of the vertical frame and the fitting groove of the lower frame of the fire protection panel of the present invention communicate with each other.
According to this configuration, the space for storing the gas can be increased by connecting the fitting grooves. As a result, for example, when one end portion of the glass panel is heated intensively and gas is generated from the one end portion, it is possible to provide a margin for receiving the gas.

The fitting groove of the frame member of the fire protection panel of the present invention may be formed with an exhaust hole for passing gas generated when the resin sheet is heated.
According to this configuration, even if the resin sheet is heated and gas is generated in the event of a fire, the rear surface side of the frame member (that is, the opposite surface to which the glass panel is fitted) is passed from the fitting groove through the exhaust hole. It is possible to prevent the gas from leaking out to the glass panel side by discharging the gas to the side of the wall of the building where the frame member is fitted).

A plurality of the exhaust holes of the fire protection panel of the present invention are formed at regular intervals.
According to this configuration, gas can be easily discharged from the fitting groove.

The fire panel of the present invention has the effect of preventing gas generated from the resin sheet sandwiched between the glass panels from seeping into the room during a fire.

Next, a method for installing the fireproof panel 1 and the action and function of the fireproof panel 1 in the event of a fire will be described.
When installing the fireproof panel 1, as shown in FIG. 3, the back plate 5B is arranged from the inner side of the back surface portion 7 of the vertical frame 5 over between the back surface portions 7, 7 and fixed. Similarly, as shown in FIGS. 5 and 7, back plates 11B and 12B are arranged and fixed from the inside between the back surfaces 7 and 7 of the frame body 11A of the upper frame 11 and the frame body 12A of the lower frame 12, respectively. do.

Next, the vertical frame 5 to which the back plate 5B is fixed is installed and fixed on the side wall surface of the room where the fireproof panel 1 is installed or on the opening formed in the side wall.
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 opening formed in the ceiling surface or the side wall between the upper parts of the vertical frames 5 .

The frame main body 12A of the lower frame 12 to which the back plate 12B is fixed is arranged and fixed to the lower part of the opening formed in the floor surface or side wall between the lower parts of the vertical frames 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 indoors so that the auxiliary protruding portion 14 is arranged near the side where the glass panel 2 is inserted.

On the groove bottom surface 6b of the fitting groove 6 of the frame main body 12A of the lower frame 12, a setting block (not shown) formed in a rectangular parallelepiped shape is arranged.
The lower end of the glass panel 2 is placed on a setting block (not shown) of the frame body 12A of the lower frame 12, and the upper end of the glass panel 2 is placed in the fitting groove 6 of the frame 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.

As a result, the glass panel 2 is housed in the opening surrounded by the vertical frames 5, 5, the frame main body 11A of the upper frame 11, and the frame main body 12A of the lower frame 12, and the other side end of the glass panel 2 is It can be fitted into the fitting groove 6 of the vertical frame 5 on the opposite side. In this state, the position of the glass panel 2 is adjusted in the horizontal direction so that the left and right side edges of the glass panel 2 are fitted into the fitting grooves 6 of the vertical frames 5 facing each other.

Each of the upper frame 11 and the lower frame 12 is provided with an auxiliary protruding portion 14, and a fixture (not shown) is inserted through the opening 20 to attach the auxiliary protruding portion 14 to each of the upper frame 11 and the lower frame 12. It is fixed to the side of the fitting groove 6 . Between the glass panel 2 and the inner side surface 6a of the fitting groove 6, a caulking material or the like is appropriately arranged.
In this state, in the fitting groove 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 or more and 20 mm or less, or about 5 mm or more and 16 mm or less. It is

When installing the vertical frame 5 , the upper frame 11 and the lower frame 12 in this way, the gap between the fitting groove 6 of the vertical frame 5 and the fitting groove 6 of the upper frame 11 and between the fitting groove 6 of the vertical frame 5 and the bottom A member such as a closing member is not installed anywhere between the frame 12 and the fitting groove 6. - 特許庁Therefore, all the spaces formed by the fitting grooves 6 and the ends of the glass panel 2 communicate with each other.
As described above, the installation of the fire panel 1 to the room or the opening formed in the wall of the room is completed.

When a fire breaks out in a room in which the fireproof panel 1 is installed, the temperature of the glass panel 2 rises, the resin sheet 4 of the intermediate layer melts, and the resin sheet 4 may generate gas. 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 face of the glass panel 2 .

When the glass panel 2 is fitted into the fitting groove 6, the fitting groove 6 is substantially sealed. There is a possibility that the liquid may leak through a slight gap between the matching groove 6 and the glass panel 2, giving off an offensive odor or causing a fire.

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

Therefore, when a fire breaks out around the fireproof panel 1, it is possible to effectively prevent the gas generated from the resin sheet 4 from emitting an offensive odor and igniting the gas. That is, since the glass panel 2 has the resin sheet 4, the fireproof panel 1 has an effect that the impact resistance is enhanced and the fireproof performance can be improved.

Also, 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 the two are communicated with each other, there is room in the space for accumulating the gas. That is, even if the fire panel 1 is locally heated and, for example, a large amount of gas is generated from one side of the vertical frame 5 of the glass panel 2, the gas spreads in the fitting groove 6 of the vertical frame 5. It flows into the fitting groove 6 of the adjacent upper frame 11 or lower frame 12 . Therefore, it is possible to increase the capacity of each portion of the frame member 3 to store gas, thereby effectively preventing the gas from being filled.

In addition, since the fire panel 1 has a gap between the bottom surface 6b of the groove and the end surface of the glass panel 2, if the glass panel 2 is tilted with respect to the frame member 3 due to the occurrence of an earthquake or the like, the glass panel 2 contact with the frame member 3 can be absorbed to some extent. Therefore, the fireproof panel 1 can effectively prevent damage to the glass panel 2 due to contact between the bottom surface 6b of the groove and the glass panel 2 or the like.

In the above-described embodiment, an example of the shape of the vertical frame 5, the upper frame 11 and the lower frame 12 is shown, but the present invention is not limited to the frame member 3 having the shape of the above-described embodiment. No. That is, the present invention can be 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 the fitting groove 6 for fitting the glass panel 2 is formed. or the lower frame shown in FIG. 8(b), it can be applied to any framed fireproof glass.

Also, an example in which the exhaust holes 10 are formed in the fitting grooves 6, 6 of the vertical frames 5, 5, the fitting groove 6 of the upper frame 11, and the fitting groove 6 of the lower frame 12 is shown. is formed in the fitting groove 6 of any one of the vertical frame 5, the upper frame 11 and the lower frame 12, the effect of the present invention can be obtained even to a small extent. In addition, since the fire panel 1 has a gap between the end surface of the glass panel 2 and the bottom surface 6b of the groove, even if the discharge hole 10 is not formed, a certain amount of gas is accumulated in the event of a fire and the gas is discharged into the glass. There is an effect that it is possible to suppress seepage to the panel 2 side.

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

Also, the frame member may not be integrally formed. For example, the auxiliary protruding portion 14 shown in FIG. 5 is formed by combining L-shaped steels as shown in FIGS. Alternatively, the vertical frame 5 shown in FIG. 3 may be formed by combining two members as shown in FIG.

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