  However, in the continuous window according to Patent Document 1 described above, when a fire occurs on the outdoor side, the one or two-layer resin hollow portion forming the frame is melted by high heat in the event of a fire or the like, and the resin hollow portion is Since it collapses as a whole, a gap communicating with the indoor side is generated, and there is a possibility that a flame or heat flows into the indoor side.

  This invention is made in view of such a subject, Comprising: Even if it has a resin-made hollow part in the frame or the frame of a shoji, the joinery which was able to ensure high fire prevention property is provided. For the purpose.

A joinery according to the present invention is a fire prevention mechanism of a joinery including a frame and a shoji housed in the frame, and a hollow resin hollow portion provided on a resin frame portion of the frame body or a resin collar portion of the shoji And a non-metallic noncombustible material that is provided in the resin hollow portion and closes the resin hollow portion in the event of a fire.
According to the present invention, when a fire or the like occurs, the resin hollow part formed on the resin frame part of the frame or the resin collar part of the shoji is easily melted by heat, but the resin hollow part is made of a nonmetallic noncombustible material. Since it is blocked, the shape of the resin hollow portion can be maintained regardless of high heat to prevent the resin hollow portion from being deformed, and flame and heat can be prevented from circulating indoors and outdoors.

Moreover, the resin hollow part may be provided over the full length of the longitudinal direction of a frame and a shoji, and the nonmetallic nonflammable material may be provided over the full length of the resin hollow part.
The resin hollow part extends over the entire length in the longitudinal direction of the frame and shoji, and the non-metallic nonflammable material in the resin hollow part extends over the entire length of the resin hollow part. This non-combustible material blocks the inside of the resin hollow portion over the entire length of the frame body and the shoji to prevent the deformation of the shape, and it is possible to prevent the flame and heat from circulating indoors and outdoors.

In addition, the frame of the joinery and the shoji are each composed of a composite sash of metal and resin, and there is no metal core in the resin hollow portion.
In the joinery according to the present invention, a metal core is not housed in a resin hollow portion provided on one of a frame and a shoji made of a composite sash of metal and resin, and a non-metallic noncombustible material such as a heating foam material. Since it is possible to prevent the resin hollow portion from collapsing and causing flames and heat to circulate indoors and outdoors when a fire occurs, the cost is lower than that using a metal core.

Also, a plurality of resin hollow parts are arranged between the frame and the panel holder provided on the shoji, and a non-metallic noncombustible material is provided in at least one resin hollow part of the plurality of resin hollow parts. May be.
Even when a plurality of resin hollow parts are arranged between the frame and the panel holder provided on the shoji, it is not necessary to install non-combustible material in all the resin hollow parts, and at least one resin hollow part is non-metallic. If a non-combustible material is provided, the resin hollow part containing the non-metallic non-combustible material can be closed in the event of a fire to maintain the shape of the resin hollow part, and other resin hollow parts that do not have a non-combustible material installed Even if it collapses due to heat, the resin hollow portion can be prevented from forming a gap through which flames and heat flow by being associated with each other by staying in that position.

  According to the joinery according to the present invention, when a fire or the like occurs, a non-metallic noncombustible material is disposed in the resin hollow portion provided between the frame and the shoji panel holder. Since the non-combustible material is closed, the shape of the resin hollow portion can be maintained regardless of the high heat, and deformation due to melting of the resin hollow portion can be prevented. Therefore, there is no gap between the frame and the shoji panel holder, so that flame and heat can be prevented from circulating indoors and outdoors, and high fireproof performance can be exhibited.

2 is a horizontal sectional view of a FIX window according to an embodiment of the present invention. FIG. It is a longitudinal cross-sectional view of the FIX window shown in FIG. It is an expanded sectional view of the resin hollow part formed in the resin vertical frame shown in FIG. 1, and a heating foam material.

Hereinafter, a FIX window (fitting window) will be described with reference to FIGS. 1 to 3 as an example of a fitting according to an embodiment of the present invention.
The FIX window 1 as a fitting according to the embodiment shown in FIGS. 1 and 2 is composed of, for example, a composite sash made of aluminum and resin. FIG. 1 shows a horizontal longitudinal section of the FIX window 1 and FIG. 2 shows a vertical sectional view. . In the FIX window 1 according to this embodiment, a frame body 6 in which an upper frame 3 and a lower frame 4 and left and right vertical frames 5 are formed in a rectangular frame shape is attached to an opening 2 of a housing.
The shoji 8 is housed in the frame 6, and the shoji 8 is mounted in the frame 6 with, for example, left and right edges of a multi-layer glass made of a pair glass 9 held by the panel holding metal fitting 10.

In the FIX window 1 shown in FIG. 2, the upper frame 3 includes a metal upper frame 12 in which an outdoor-side metal upper frame 12 a attached to the outdoor side and an indoor-side metal upper frame 12 b are connected via a heat insulating material 14, A resin upper frame 13 provided on the indoor side is connected and configured. The upper end portion of the pair glass 9 abuts the packing 16 provided on the lower extension portion 12c of the metal upper frame 12 on the outdoor side, and the pressing edge 15 fitted and connected to the resin upper frame 13 on the indoor side. It is held in contact with the packing 16 provided on the surface.
Similarly, the lower frame 4 includes a metal lower frame 19 in which an outdoor-side metal lower frame 19a attached to the outdoor side and an indoor-side metal lower frame 19b are connected via a heat insulating material 18, and a resin provided on the indoor side. The lower frame 20 is connected. The lower end portion of the pair glass 9 is held in contact with the packing 16 provided on the metal lower frame 19 on the outdoor side and the packing 16 provided on the resin lower frame 20 on the indoor side.

Further, in the frame body 6 shown in FIG. 1, the left and right vertical frames 5 are formed in line symmetry, and therefore will be described by using the left vertical frame 5 shown in the enlarged view of FIG. In other words, the vertical frame 5 connects the metal vertical frame 22 attached to the outdoor side of the housing and the resin vertical frame 23 formed with a plurality of hollow portions (hollow portions) provided on the inner side on the inside. It is prepared.
In addition, the pair glass 9 of the shoji 8 is hold | maintained by the panel holding | maintenance metal fitting 10 by which the edge part of right and left was formed in the cross-sectional substantially U shape. The pair glass 9 held by the left and right panel holding metal fittings 10 has a netted outer glass 26 and an inner glass 27 attached via spacers. For example, a heating foam material 28 is fixed as a non-combustible material at a position on the inner surface of the panel holding metal 10 that faces the end of the netted outer glass 26. The space between the ends of the glass 9 can be sealed.
Further, the left and right end portions of the pair glass 9 are held with the packing 16 provided on the branch receiving portion 22a extending in the direction of finding the metal vertical frame 22 at the outdoor side end portion, and the indoor side end portion is a resin vertical frame. The packing 16 provided on the pressing edge 24 fitted to the contact 23 is held in contact therewith.

Next, as shown in FIGS. 1 and 3, the left and right resin vertical frames 23 are mounted between the metal vertical frame 22 and the panel holding metal 10. Two resin hollow parts 23a and 23b are formed in parallel. On the outdoor side of these resin hollow portions 23a and 23b, an outdoor-side extending portion 23c is formed that extends to the branch receiving portion 22a along the metal vertical frame 22 and holds and holds the end portion.
And the fitting hole 23d for fitting the pressing edge 24 in order to hold | maintain the pair glass 9 is formed inside the indoor side edge part of the resin hollow parts 23a and 23b.

In addition, the heating foam material 30 is installed on one of the two resin hollow portions 23a and 23b, for example, the wall portion 23e that forms a boundary with the other resin hollow portion 23b in the resin hollow portion 23a on the panel holding metal fitting 10 side. Has been. The heating foam material 30 is not installed in the other resin hollow portion 23b. The heating foam material 30 is fixed to the wall portion 23e by bolts 31. In this case, the tip of the bolt 31 may protrude into the other resin hollow portion 23b. Alternatively, the heating foam material 30 may be fixed to the wall portion 23e with an adhesive or the like instead of the bolt 31.
In order to attach the heating foam material 30 to one resin hollow portion 23a, when assembling the resin vertical frame 23, the heating foam material 30 is fixed to the outside of the wall portion 23e of the other resin hollow portion 23b with a bolt 31, Thereafter, one resin hollow portion 23a may be assembled to form the resin vertical frame 23.

In order to prevent the pair glass 9 fixed to the panel holding metal fitting 10 from being removed from the holding position in the event of a fire, a heated foam material is formed on one resin hollow portion 23a adjacent to the panel holding metal fitting 10 where heat is likely to rise first in the event of a fire. 30 is preferably installed.
However, the heating foam material 30 may be fixed in the other resin hollow portion 23b instead of the one resin hollow portion 23a. Even in this case, the thermal foaming material 30 is thermally expanded, so that the shape of the other resin hollow portion 23b can be maintained and the deformation of the mold can be prevented. One resin hollow portion 23a remains at that position even when melted by heat, and is supported by being connected to the panel holding metal fitting 10 of the pair glass 9, thereby preventing the formation of a gap.

Moreover, the resin hollow portions 23a and 23b extend in the vertical direction so as to have the same length as the vertical length of the vertical frame 5 and the shoji 8, and the heating foam material 30 fixed in the resin hollow portion 23a is also the same. It is assumed that the resin hollow portions 23a and 23b extend over the entire length.
Therefore, for example, when a fire occurs on the outdoor side, the heated foam material 30 provided in one resin hollow portion 23a foams and thermally expands, so that one resin hollow portion 23a is melted by heat and loses its shape. Can be prevented and its form can be maintained. The other resin hollow portion 23b is not provided with a heating foam material, but by maintaining the form of the one resin hollow portion 23a, the other resin hollow portion 23b also dissolves but remains in that position and is carbonized. However, since it is connected to one of the resin hollow portions 23a, the shape is prevented from being lost, and the heat transfer on the indoor side is hindered. The plurality of resin hollow portions 23 a and 23 b of the resin vertical frame 23 and the heating foam material 30 constitute a fire prevention mechanism 33.
In the FIX window 1 according to the present embodiment, if a metal core material is provided in the resin hollow portions 23a and 23b of the resin vertical frame 23, heat is easily transmitted to the indoor side through the metal core material, and the FIX window 1 as a whole. This is not preferable because the heat insulation performance of the resin is lowered.

The fire prevention mechanism 33 of the FIX window 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next.
For example, when a fire occurs on the outdoor side of the FIX window 1 and is exposed to a high temperature, the resin vertical frame provided between the panel holding metal fitting 10 that holds the pair glass 9 of the FIX window 1 and the metal vertical frames 22 on both sides thereof. Since No. 23 has a relatively low heat resistance, the melting starts earlier than the metal vertical frame 22 such as an aluminum alloy, the pair glass 9 or the like.

  Therefore, the two sets of resin hollow portions 23a and 23b arranged on the outdoor side of the resin vertical frame 23 start thermal melting. However, in the one resin hollow portion 23a, the heated foam material 30 provided therein is foamed by heat and thermally expanded, so that the form of the one resin hollow portion 23a is held by the thermally expanded heat foam material 30. The other resin hollow portion 23b does not contain a heated foam material and melts under high heat. However, since the shape of the adjacent one of the resin hollow portions 23a is maintained, the other resin hollow portion 23b connected thereto is retained. The shape loss of is suppressed and stays in that position, and the shape loss is delayed.

Therefore, the pair glass 9 and the panel holding metal fitting 10 are delayed from coming out of their positions, and the time until the flame and heat are communicated indoors and outdoors can be delayed by delaying the generation of the indoor and outdoor gaps.
Then, when the resin hollow portions 23a and 23b arranged in parallel with the resin vertical frame 23 are finally melted by heat and lose their shape, the pressing edges 24 that support the pair glass 9 drop off from the resin vertical frame 23.
The above description is for a case where a fire has occurred on the outdoor side, but since the heating foam material 30 is provided in the resin hollow portion 23a of the resin vertical frame 23 even when a fire has occurred on the indoor side, the resin Dissolution and loss of shape of the hollow portions 23a and 23b can be suppressed.

As described above, according to the fire prevention mechanism 33 of the FIX window 1 according to the present embodiment, the resin hollow portions 23 a and 23 b of the resin vertical frame 23 provided between the panel holding metal fitting 10 of the pair glass 9 and the metal vertical frame 22. By fixing the heating foam material 30 on one side, the heating foam material 30 is thermally expanded in the event of a fire or the like, and the shape of one resin hollow portion 23a is maintained to prevent the deformation of the other resin hollow portion 23b. Dissolution and loss of shape will also be delayed. Therefore, the resin vertical frame 23 can be prevented from collapsing due to shape loss, thereby inhibiting heat transfer, and delaying the communication of the flame and heat from the gap indoors and outdoors and the disengagement of the shoji 8 can be delayed.
Moreover, in the present embodiment, the flame is formed only by the heating foam material 30 provided in one resin hollow portion 23a of the resin vertical frame 23 without installing a metal core such as steel in the resin vertical frame 23. Further, since it is possible to delay the communication of heat and heat indoors and outdoors from the gap, the manufacturing cost of the fire prevention mechanism 33 of the FIX window 1 can be reduced. Moreover, this embodiment can prevent a flame and heat from circulating indoors and outdoors without providing a metal core or the like, is low in cost, and can suppress a decrease in heat insulation performance.
