A sash A according to an embodiment of the present invention will be described below with reference to the drawings. In the following description, the same reference numerals in different figures denote portions having the same function, and duplication of description in each figure will be omitted as appropriate.

[Configuration of sash]
As shown in FIGS. 1 to 3, the sash A shown in this embodiment is arranged such that the inner shoji C1 and the outer shoji C2 open and close in the viewing direction with respect to the frame B provided in the opening 101 of the frame 100. It is a supported double sliding window.

[Frame configuration]
As shown in FIGS. 1 to 3, the frame B is composed of a lower frame 1, an upper frame 2, and left and right vertical frames 3 and 4. As shown in FIG.
As shown in FIGS. 2 and 5, the lower frame 1 includes a lower substrate 10 on which an outer rail 1a is erected, an upper substrate 11 on which an inner rail 1b is erected, and a lower substrate below the upper substrate 11. An opening 12a has a concave portion 12 formed between 10 and an upper substrate 11 so as to face the outer rail 1a in the viewing direction, and the upper end of the outer rail 1a is positioned lower than the upper substrate 11 in a stepped shape. is formed in

As shown in FIGS. 2 to 5, the lower frame 1 is provided with a heating foam material D. As shown in FIGS.
Here, the heating foam material D is foamed and expanded by the heat acting on the sash A in the event of a fire. It can block the path through which poisonous gas or the like enters the house.

As shown in FIGS. 2 and 3, the lower frame 1, the upper frame 2, and the vertical frames 3 and 4 are provided with an airtight material A1 so as to cover the entire periphery of the exterior surface B1 of the frame B. .
Further, as shown in FIG. 3, an airtight material A2 is provided so as to extend over the entire length in the vertical direction of the viewing surface B2 on the outdoor side of the meeting frame C10 of the inner shoji C1.

The airtight material A1 is attached to the indoor side of the stiles (upper and lower horizontal stiles and vertical stiles) C11 of the inner shoji C1, which is pulled indoors so as to approach the frame B by the locking operation of the crescent A3 (see FIG. 1). Airtightness around the sash A is ensured by closely contacting the surface B3 with the indoor facing surface B4 of the stiles (upper and lower horizontal stiles and vertical stiles) C21 of the outer shoji C2.
In addition, the airtight material A2 closely contacts the meeting frame C10 of the sash A and the meeting frame C10 of the sash A by bringing the meeting face B5 on the indoor side of the meeting frame C20 of the outside shoji C2 drawn to the inside shoji C1 into close contact with the locking operation of the crescent A3. It ensures airtightness with the meeting frame C20.
That is, by securing the airtightness of the sash A with the airtight material A1 and the airtight material A2, soundproofing, watertightness, and heat insulation can be enhanced.

[Arrangement configuration of heating foam]
As shown in FIGS. 2 to 5, the heating foam material D is formed in a tape shape, and extends longitudinally along the inner peripheral side of the upper substrate 11 of the lower frame 1 on the inner peripheral side projection surface 11a located on the outdoor side of the inner rail 1b. It is attached by gluing along the direction.
As shown in FIGS. 2 to 5, in the closed state of the inner shoji C1 and the outer shoji C2, the heated foam material D is positioned directly below the inner shoji C1 and interferes with the opening and closing of the inner shoji C1. It is considered to be thick enough not to become

As for the arrangement configuration of the heated foam material D, in the closed state of the inner shoji C1 and the outer shoji C2, the heated foam material D may be arranged only on the facing surface 11a on the inner shoji C1 side, or on the outer shoji C2 side. (not shown).

Here, the effect of the configuration in which the heating foam material D is arranged at the above-described portion will be described with reference to FIGS. 6(a) and 6(b).
When the heat from the fire acts on the sash A from the outside or the inside, the heated foam material D foams and expands due to this heat, and as shown in FIGS. , and expands in a range from directly below the inner rail 1b to the lower substrate 10. As shown in FIG.

Specifically, as shown in FIG. 6A, the heated foam material D directly under the inner shoji C1 is in close contact with the entire surface of the inner rail 1b on the outdoor side 10b, and the inner shoji C1 While foaming and expanding so as to close the gap C12 below, it extends from the projected surface 11a of the upper substrate 11 to the projected surface 10a of the lower substrate 10 to block the opening 12a of the recess 12 and the roof of the outer rail 1a of the lower substrate 10. It foams and expands so as to adhere to the inner viewing surface 13a.

That is, the heated foam material D foamed and expanded under the inner shoji C1 closes the gap C12 under the inner shoji C1, so that the flames, smoke, and toxic gases generated on the outdoor side flow from the inner shoji C1 side to the indoor side. intrusion can be prevented.
Furthermore, the heating foam material D adheres to the entire exterior surface 10b of the inner rail 1b, so that the inner rail 1b can be protected from fire and heat.
Furthermore, the heating foam material D extending from the prospective surface 11a of the upper substrate 11 to the lower substrate 10 closes the opening 12a of the recess 12, thereby blocking flame and heat from entering the recess 12. The upper substrate 11 and the lower side of the upper substrate 11 can be protected from flames and heat.

On the other hand, as shown in FIG. 6(b), the heated foam material D on the outer shoji C2 side is located between the outer facing surface 10b of the inner rail 1b and the inner facing surface B4 of the outer shoji C2. It foams and expands so as to fill it.

That is, the heated foam material D foamed and expanded on the side of the outer shoji C2 fills the space between the outer surface 10b of the inner rail 1b on the outdoor side and the inner surface B4 of the outer shoji C2 on the indoor side. Rail 1b and upper substrate 11 can be protected from flames and heat.
Furthermore, even if the airtight material A1 of the lower frame 1 is melted by flames and heat from the outdoor side of the outer shoji C2 and a gap is created, the gap can be closed with the heated foam material D, so the gap can be formed on the outdoor side. It is possible to prevent fire, smoke, and toxic gas from entering the room from the outside shoji C2 side.

The foaming/expansion of the heating foaming material D due to heat is the same as in the case of a fire breaking out indoors even when a fire breaks out indoors. The lower side of the upper substrate 11 can be protected from flames and heat.
In addition, since the above-mentioned gap C12 and the gap due to melting of the airtight material A1 of the lower frame 1 are closed by the foaming and expansion due to the heat of the heating foam material D, the flame, smoke, and toxic gas generated indoors C1 It is possible to prevent the outflow of oxygen from the side and the outer shoji C2 side to the outdoor side, and prevent the inflow of oxygen from the outdoor side to the indoor side.
In other words, by preventing the outflow of flames, smoke, and toxic gases to the outside, it is possible to prevent the spread of fire to the neighborhood and the damage caused by smoke and toxic gases. Fire growth can be suppressed.

Therefore, fire prevention measures are taken by a simple structure in which the heating foam material D is arranged along the longitudinal direction on the inner peripheral side projection surface 11a located on the outdoor side of the inner rail 1b of the upper substrate 11 of the lower frame 1. As a result, it is possible to improve the fireproof performance of the sash A and secure evacuation time in the event of a fire.

As shown in FIGS. 2 to 5, the heating foam material D according to the arrangement configuration in this embodiment is a member (stopper 200, water stop plate 201) and holes (drainage holes 202).
In this case, as for the stopper 200 portion, the foamed and expanded heated foam material D can reach around the stopper 200, so even if there is the stopper 200, the inner rail 1b and the upper substrate 11 on the side of the outer shoji C2 can be prevented. Can be protected from fire and heat.
It should be noted that the heating foam material D may be arranged on the stopper 200 as long as it does not hinder the opening and closing movement of the inner shoji C1.

As for the drain holes 202, as shown in FIG. 4, the heat-foaming material D is removed and the drain holes 202 are exposed. Since the drain hole 202 is closed when the water is turned on, it is possible to prevent flames, smoke, and toxic gas from entering from the drain hole 202.例文帳に追加
In addition, in the case of the lower frame 1 which does not have the drainage hole 202, it is not necessary to process the heating foaming material D to remove the drainage hole 202 from the heating foaming material D. FIG.

On the other hand, as for the water stop plate 201, as shown in FIGS. 4 and 5, since it is located directly under the meeting frame C10 of the inner shoji C1, the heating foam material D is divided into two with the water stop plate 201 as a boundary. However, depending on the shape of the water stop plate 201 , it is conceivable that the foamed and expanded heated foam material D may not reach above the water stop plate 201 .
For this reason, as shown in FIGS. 3 and 7, the second heating foam material D' should be arranged below including at least the lower end of the indoor facing surface C21 of the meeting frame C20 of the outer shoji C2.
That is, the second heating foam material D′ arranged on the indoor-side viewing surface C21 of the meeting frame C20 expands and expands, so that the water stop plate is formed between the meeting frame C10 and the meeting frame C20. The upper side of 201 can be reached by a second heated foam D'.
As a result, the gap C12 below the inner shoji C1 located above the water stop plate 201 can be closed, and the second outer surface 10b of the inner rail 1b facing the water stop plate 201 is provided on the outside surface 10b. The heat foaming material D' can be adhered, and the second heat foaming material D' is caused to reach the lower substrate 10 from the projected surface 11a of the upper substrate 11 on which the water stop plate 201 is arranged, so that the opening 12a of the recess 12 is formed. can be blocked.
Therefore, even if the heated foam material D does not reach above the water stop plate 201, the second heated foam material D' reaches above the water stop plate 201, so that flames and smoke are generated around the water stop plate 201.・It is possible to prevent the occurrence of intrusion paths for toxic gases.
In addition, in the case of a sash that does not have the water stop plate 201, the second heating foam material D' is not required, and the heating foam material D need not be divided into two parts.

[Specific example of heat foaming material]
As for the heat foaming material D, as shown in FIG. 8, a base material layer D1, a refractory material layer D2 that is foamed by heating and laminated on the base material layer D1, and a fireproof material layer D2 laminated on the refractory material layer D2. A three-layer structure having a surface material layer D3 can be exemplified.
The base material layer 1, the refractory material layer D2 and the surface material layer D3 are flexible and can be rolled into a roll when stored, and can be stretched linearly when used.
An adhesive layer (not shown) and a release material layer (not shown) covering the adhesive layer are provided on the lower surface side of the base material layer 1, and the upper substrate 11 can be removed by peeling off the release material layer. It can be attached to the surface 11a.
The surface material layer D3 has water resistance and water repellency, and is made of a synthetic resin material with a smooth surface. It has the property of preventing dirt from sticking, and makes it easy to wipe off the dirt that has adhered.
Such a heating foam material D has the effect that it can be easily attached to the projected surface 11a of the upper substrate 11 by the adhesive layer provided on the base material layer D1, and the refractory material layer D2 is protected by the surface material layer D3. In addition, the lower frame 1 does not impair the drainage performance, is resistant to dirt, and has the effect of easily removing the dirt.

The above-described heat foaming material D is an example, and as another configuration, for example, the surface material layer D3 of the heat foaming material D can be colored, or a colored layer can be further laminated on the surface material layer D3 ( not shown).
Further, the thermally foamed material D may be one without the base material layer D1 or the surface material layer D3, or one without the base material layer D1 and the surface material layer D3 (not shown).
In addition, the heating foam material D without the surface material layer D3 may be directly colored on the refractory material layer D2, or may be laminated with a colored layer (not shown), or may be a refractory material laminated on the base material layer D1. A resin layer may be laminated on the upper surface of the material layer D2, and the upper surface of the resin layer may be directly colored or may be laminated with a colored layer.
The color to be colored or the color of the colored layer is arbitrary. For example, by using the same color as the color of the lower frame 1, the existence of the heated foam material D can be made inconspicuous.

The sashes according to the embodiments of the present invention have been described in detail above with reference to the drawings. Even if there is a change in design, etc., it is included in the present invention.
In addition, each of the above-described embodiments can be combined by diverting each other's techniques unless there is a particular contradiction or problem in the purpose, configuration, or the like.
