2. Description of the Related Art Conventionally, in a sash provided at a window opening of a building, a composite sash having a metal frame such as aluminum or an indoor exposed portion of a metal casing covered with wood or a resin member is widely used.
When making such a sash a fireproof structure, the frame of aluminum or wood that is widely used for normal sashes cannot be used because it cannot withstand high temperatures for a predetermined time, such as iron or stainless steel. Only metal frames that can withstand high temperatures could be used.
Since iron and stainless steel give a cold impression of metal, cover the exposed part of the metal frame on the indoor side with wood or resin material to eliminate the cold impression of the metal received when looking at the sash from the indoor side. Although there are things that give a feeling, it is difficult to use designs of various colors and designs, it is difficult to unify the design of the sash and its surroundings, and it is not possible to improve the design It was.
Moreover, since the window glass used for the sash of the conventional fire prevention structure can also endure high temperature for a predetermined time, it is necessary to use the glass with a net wire for the glass exceeding a certain size, and there is a feeling of opening. It was difficult to realize the sash.
Since wood can be used in various colors and designs, it is possible to unify the design of the sash and its surroundings and improve the design, but the sash using a wooden frame is durable It is not in widespread use due to problems with fire and fire.

The fireproof sash using the wood frame of the present invention, when exposed to a high temperature at a high temperature of 750 ° C. or higher for a certain period of time, the waterproof cover of the aluminum melts, and the outer surface of the wood frame and the fence once Although it burns and the surface is carbonized, it has been confirmed by experiments that it will continue to hold the window glass 30 and 40 securely within 20 minutes without burning to the inside of the wood frame and the cage.
In addition, in the case of a double glazing structure as shown in FIG. 6, when a fire occurs on the side of the laminated glass (outside the window), the surface of the laminated glass is exposed to a high temperature at a high temperature of 750 ° C. Although the glass plates 31 and 32 are cracked by this high temperature, the transparent inorganic composite material 33 bonded to the glass plates 31 and 32 is softened and melted by the high temperature and turns white, but at least 20 minutes. In the meantime, it has an ability to securely hold the adhesion of the glass plates 31 and 32. For this reason, even when the surface of the laminated glass is exposed to a high temperature of 750 ° C. for 20 minutes, the plate glasses 31 and 32 in which cracks have occurred do not fall off for 20 minutes.

Due to the heat insulation effect of the argon gas sealed in the space between the laminated glass and the thick glass 41, the high temperature of the surface of the laminated glass is blocked by the thick glass 41. Experiments have confirmed that no cracks occur and no ignition occurs on the thick glass 41 side for 20 minutes.
In addition, when a fire occurs on the side of the thick glass 41 (indoor) and the surface of the thick glass 41 is exposed to a high temperature at a high temperature of 750 ° C. or higher for a certain period of time, the thick glass 41 is cracked due to this high temperature. However, it falls off after a certain dropout time.
Until the thick glass 41 falls off, the laminated glass blocks the high temperature of the surface of the thick glass 41 due to the heat insulating effect of the argon gas sealed in the space between the laminated glass and the thick glass 41. When the thick plate glass 41 is dropped, the surface of the laminated glass is exposed to a high temperature of 750 ° C. or higher, and the plate glass 31 and 32 is cracked by this high temperature, and is a transparent inorganic composite material bonded to the plate glass 31 and 32. Is softened and melted at a high temperature and turns white, but has the ability to reliably maintain the adhesion of the glass sheets 31 and 32 for at least 20 minutes. For this reason, even when the surface of the thick glass 41 is exposed to a high temperature of 750 ° C. or higher for 20 minutes, it has been confirmed by experiments that it does not ignite on the side of the laminated glass for 20 minutes.
