DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a fire protection device for a wooden sash according to the present invention will be described with reference to FIGS.

As shown in FIG. 1, the present invention is directed to a wooden sash consisting of a wooden outer frame 4 and an opening / closing glass door 2 made of a plate glass 5 inside a wooden frame 1 bound to a wall opening of a building. In the illustrated example, the glass door 2 is hinged on one side with respect to the surrounding frame 1 by the hinge 11 so that the glass door 2 can be pivoted to open and close to the left and right. However, the opening and closing method is arbitrary. When the glass door 2 is opened and closed as described above, it is necessary to provide the gap 3 between the wooden surrounding frame 1 and the glass door 2 so as not to hinder the rotation of the glass door 2.

Generally, a gap portion 6 is usually formed between the wooden outer frame 4 and the plate glass 5 which constitute the opening / closing glass door 2.

As described above, the present invention is a wooden sash formed between the wooden frame 1 and the glass door 2 of the wooden sash with the opening / closing glass door, and between the wooden outer frame 4 and the plate glass 5 of the glass door 2. In order to prevent flame, smoke, and hot air from blowing through the gaps 3 and 6 communicating with the inside and outside of the gaps 3, 6
In addition, the heat-sensitive foam material 7 is interposed along its length, and the heat-sensitive foam material 7 is foamed and expanded by the heat at the time of a fire to fill and close the gaps 3 and 6 with the foam material 7. The heat flow was blocked.

The heat-sensitive foam 7 interposed in the gaps 3 and 6 is either the inner surface of the wooden frame 1 or the outer surface of the wooden outer frame 4 of the glass door 2 facing each other in the gap 3 as shown in the figure. Either embedding or sticking along the length direction of one of the surfaces is arbitrary, and the gap portion 6 in the opening / closing glass door 2 is arbitrary.
Then, either one of the inner surface of the wooden outer frame 4 and the edge of the glass sheet 5 facing each other in the gap 6 is attached to the edge side of the glass sheet 5 as shown in the illustrated example, or the inner surface of the wooden outer frame 4 is covered with the above-mentioned material. It is optional to embed or adhere as described above, or simply insert and interpose in the gap portion 6 without particularly binding.

Further, the heat-sensitive foam material 7 has an appropriate thickness corresponding to the width of the gaps 3 and 6, and the heat-sensitive foam material 7 is in the depth direction of the gap portions as shown in the drawing. When the inner and outer ends of the sash are divided into two parts and are spaced apart from each other, the heat-sensitive foam material 7 on the side where the fire occurred inside or outside the sash is foamed and blocked by the heat of the sash first. There is an advantage that the spread of fire can be prevented and the use of the expensive heat-sensitive foam material 7 can be saved.

As the heat-sensitive foam material 7, a generally known commercially available material is used.

Further, the plate glass 5 of the glass door 2 is a wooden outer frame 4
After the assembly, the peripheral edge is conventionally pressed down with a wood material 8 or the like to prevent it from coming off due to wind pressure. The window opening of is open to the inside and outside,
It is necessary to eliminate the inconvenience of free passage of flame and smoke.

In order to cope with this, the present invention uses a wooden outer frame 4
The outer surface of the whole or part of the edge of the sheet glass 5 assembled on the outer surface is held by the metal fitting 9 having an L-shaped cross section, and the L-shaped metal fitting 9 prevents the glass sheet 5 from falling off as long as the wood part remains as a heat insulating layer even in a fire did.

In the illustrated example, the opening / closing glass door 2 has a rectangular shape, and the L-shaped metal fitting 9 is attached along the upper and lower edges thereof, but the shape of the glass door 2 is arbitrary.

The metal fitting 9 having the L-shaped cross section is a relatively long nail 1.
By 0, it is fixed to the inner edge of the wooden outer frame 4 and is kept attached to the wooden outer frame 5 which is weakened by heat.

In the figure, 12 is a water barrier attached along the lower edge of the rectangular glass door 2, and 13 is a packing material.

Thus, in the wooden window sash with the opening / closing glass door, the gap 3 between the wooden enclosure 1 and the opening / closing glass door 2 and the gap 6 between the wooden outer frame 4 of the glass door 2 and the plate glass 5 are heat-sensitive when a fire occurs. A wooden sash capable of preventing fire in the event of fire was obtained by automatically closing it with the foam material 7 and preventing the communication between the window opening and the outside due to the falling of the plate glass 5 with the L-shaped metal fitting 9.

[0019]

[Effects of the Invention] According to the present invention, in a wooden sash with an opening / closing glass door, a heat-sensitive foam material is provided in the gap provided between the wooden surrounding frame and the opening / closing glass door in the longitudinal direction of the gap. By interposing, the gap is automatically filled and closed by foam expansion of the heat-sensitive foam material due to the temperature of hot air when a fire occurs, and the gap between the wooden outer frame and the sheet glass in the opening / closing glass door is also heat-sensitive foamed. I tried to close it by foaming the material, so flames from these gaps,
It prevents smoke from blowing through, and the glass plate of the glass door keeps its original shape as long as it does not burn down even if the wood part is burned and carbonized due to a fire. The fireproof wood with an open / close glass door that prevents flames, smoke, etc. from entering and blowing from the opening due to the falling of the sheet glass, and, in combination with the fireproof structure of the gap, accurately prevents the adverse effects of fire burning and fire spreading. It has a sash effect.
