とである。“Prior Art” Generally, it is required that a building does not easily cause a fire and that even if a fire occurs, it is difficult to spread the fire. When a fire occurs here, considering the safety against flames, the properties of the fire are ignitability of building materials, fire spreadability, amount of combustibles, thermal conductivity, opening ratio of windows, doors, etc. Although it is affected by various conditions such as the combustion conditions of the fire source, it is especially important to prevent the spread of fire and the possibility of evacuation in the event of a fire. That is, it is possible to sufficiently prevent the propagation of smoke.

を形成することがなされている。"Problems to be solved by the invention" By the way, doors installed in buildings have various structures due to decorative considerations, among them are vertical frames, upper frames and lower frames. There is known a door having a configuration in which the periphery is hardened, a mirror plate is fitted inside the periphery, and the mirror plate is fixed by nailing or adhesion. In a door of this type, as shown in FIG. 3, usually, a groove portion 1a is formed on the inner peripheral side of the frame 1 and a thin fitting piece 2a is formed on the outer peripheral portion of the end plate 2, and the groove portion 1a is formed. The end plate 2 is joined to the frame 1 by fitting the fitting piece 2a, and further, a stepped portion or a concavo-convex portion is formed on the inner peripheral portion of the frame 1 and the outer peripheral portion of the fitting piece 2a for the purpose of adjusting the appearance of the joined portion. Has been done.

In some cases, there is a problem that the end plate 2 falls off the frame 1 and falls, and the space created by the end plate 2 becomes a fire spread passage, and there is a drawback that the fire prevention performance is deteriorated. Further, in the door having the structure shown in FIG. 3, even when the end plate 2 does not fall off, since the thickness of the boundary portion between the frame 1 and the end plate 2 is small, this portion is spread when the fire spreads. There was a problem of passing flames and smoke through.

8 is attached. The frame member 17 has a groove portion 17a formed on the inner peripheral side thereof and a groove portion 17b formed on the outer peripheral side thereof to form a sectional shape as shown in FIG. Further, each frame member 17 is provided by fitting the inner peripheral end of each frame into the outer peripheral recess 17b and the outer peripheral end of the end plate 18 into the inner peripheral recess 17a. There is. In addition,
The thickness of the end plate 18 is the same as the thickness of each frame. A thermal foam member 20 is interposed between the bottom of the groove 17a of the frame member 17 and the end plate 18, and
Thermal foam materials 21 and 22 are also interposed between the groove portion 17b of the frame member 17 and the inner peripheral portion of the frame.

All of 8 are made of flame-retarded wood. This flame-retarded wood is obtained by impregnating wood such as Nanyo cedar with dicyandiamide, phosphoric acid, boric acid and a partial reaction product of water in a solid content of 100 kg or more per 1 m 3 of wood. It is possible to impregnate 100 kg or more (5 times as much as usual) with the combination of the wood and the chemicals, and by such an impregnation action, wood having sufficient performance as a semi-incombustible material can be obtained.

Since 8 and 8 are made of flame-retardant wood, they exhibit sufficient fireproof performance. Moreover, since the end plate 18 is formed to have the same thickness as the frame, only the end plate 18 will not be burned earlier than the frame when it is heated during a fire. Further, since the frame member 17 made of flame-retardant wood and having a sufficient thickness is provided at the boundary portion between the frame and the end plate 18, the frame member is thinner than the conventional door which is formed around the frame member. Fire resistance at the part does not deteriorate. Further, the frame and the frame member 17
Since the thermal foam materials 21, 22 are provided between the frame member 17 and the end plate 18, the thermal foam materials 20, 21, 22 expand when a fire occurs. Since the gaps are filled, the end plate 18 does not fall off even if the fixing force of the nail or the adhesive agent that fixes the end plate 18 decreases due to heat. In addition, since the thermal foam materials 20, 21, 22 close the gaps between the respective frames, the frame member 17 and the end plate 18, the flame and smoke are not leaked. That is, since the door D of this example has a higher combustion resistance than that of the conventional door, it is less likely to be burned in the event of a fire, and has a feature of excellent fire prevention performance. Further, even if the frame member 17 is carbonized in the event of a fire, the expanded thermal foam materials 20, 21, 22 support the end plate 18, so that the end plate 18 is prevented from falling and a sufficient fire prevention performance is exhibited.

Although the vertical bars 15, 16 and the end plate 18 are formed to have the same thickness, the thicknesses may be different. Further, the frame members or cross members to be provided when constructing the door may be vertical bars and horizontal bars, or may be the required number of vertical frames and horizontal frames. Further, it goes without saying that the outer surface shape of the frame member 17 can be formed in an appropriate shape in consideration of the decorative surface of the door D.

Since the gap between the mirror plate and the mirror plate is filled, the mirror plate should be removed even if the fixing force of the nails or adhesives that fix the mirror plate decreases due to the heat of the fire. It is possible to prevent the spread of fire and to prevent flame and smoke from leaking from the boundary portion between the vertical material, the horizontal material and the end plate. Further, since the frame member is provided at the boundary portion between the vertical member and the horizontal member and the end plate, the fireproof property in the frame portion is improved as compared with the conventional door in which this portion is formed thin.
即ち、この考案のドアは従来のドアよりも燃焼抵抗が大

た熱発泡材が鏡板を係止するので鏡板の落下を阻止する
ことができて充分な防火性能を発揮する。Further, even if the frame member is carbonized in the event of a fire, the expanded thermal foam material locks the end plate, so that the end plate can be prevented from falling and a sufficient fire prevention performance is exhibited.
