  Further, when the joinery 1 is heated by being exposed to a flame, for example, when heated by a flame outside the room, the portion of the central wall portions 11e and 12e on the right frame 14 side located outside the room is melted. Even if it is done, it is possible to prevent the portion of the central wall portions 11e, 12e on the left frame 13 side located on the indoor side from being melted by the relay member 22. Further, when heated by the indoor flame, even if the portion of the central wall portions 11e and 12e on the left frame 13 side located on the indoor side is melted, the relay member 22 causes the central wall portions 11e and 12e to melt. It is possible to prevent the portion on the right frame 14 side located on the outdoor side from melting. For this reason, even if it is exposed to a flame from either the indoor side or the outdoor side, it is possible to prevent the indoor and outdoor from penetrating in the upper part and the lower part of the summing part 10b.

  At this time, even if it is exposed to the flame from either the indoor side or the outdoor side, the upper arm 31, 41, the lower arm 32, 42, and the door-end arm 33, 43 The frame-side reinforcing member 20, the relay member 22, the hanging fitting 23, and the engaging member 25 are foamed together with the thermally expandable graphite 38 so that the space between the frame body 10 and the inner and outer obstacles 3 and 4 is expanded. Since it is filled with the expanded graphite, it is possible to prevent the interior and the exterior from penetrating between the frame body 10 and the inner and outer children 3 and 4.

  For this reason, even if it has the central wall parts 11e and 12e which guide the inner and outer children 3 and 4 so as to be able to be drawn and are connected in the direction of finding and connected to the inside and outside of the room, a frame made of a synthetic resin that does not easily penetrate the flame. It is possible to provide the joinery 1 including the body 10.

  Further, when exposed to a flame, the inner frame 3 and the outer frame are arranged on the hook-shaped portion 23c of the hanging metal fitting 23 fixed to the metal frame side reinforcing member 20 fixed to the frame 2 together with the relay member 22. Since the hook part 36a of the hook metal fitting 36 included in 4 is engaged, even if the frame 10 is melted, it is possible to hold the inner and outer limbs 3 and 4. Here, the hanging metal fitting 23 is not necessarily fixed to the frame-side reinforcing member 20 together with the relay member 22, but may be fixed to the frame-side reinforcing member 20 via the relay member 22.

  Further, when the joinery 1 is heated by being exposed to a flame or the like, the space between the relay member 22 and the hanging metal fitting 23 is filled with the expanded graphite 38, so that the summing unit 10b It is possible to more reliably prevent the flame from penetrating.

  Further, when the joinery 1 is heated by being exposed to a flame or the like, the hook fitting 36 provided in the summing portion 10b of the inner shoji 3 and outer shoji 4 and the door side of each shoji 3, 4 are provided. Since the hook fittings 36 thus engaged respectively engage with the hanging fittings 23, both the inner and outer children 3 and 4 are held at two positions on both ends in the direction of finding. For this reason, it is possible to hold the inner shoji 3 and the outer shoji 4 more reliably.

  Further, the engagement piece 25a of the metal engagement member 25 and the hanging metal fitting 23 are brought into contact with each other at the corner of the frame body 10 which is a joint portion between the upper frame 11, the left frame 13, and the right frame 14. Since it is connected and connected, it is possible to prevent the flame from penetrating even at the corner where it is difficult to place the reinforcing member in the frame 10 made of synthetic resin in which the ends of 45 degrees are joined.

  Further, since the relay member 22 arranged in the summoning section 10b is provided with the windshield member 24 at the tip, not only the relay member 22 is prevented from penetrating flames in the event of a fire, but also the inner and outer children 3 and 4. The windshield member 24 can be easily provided between the two.

  In the above embodiment, the hanging metal fitting 23 and the hook metal fitting 36 that engages with the hanging metal fitting 23 are provided at the summing portion 10b and the door end portion that are both ends in the direction in which the inner shoji 3 and the outer shoji 4 are found. Although demonstrated, it is not restricted to this, What is necessary is just to be provided in the summit part 10b and the position of the door-end side from the summon part 10b.

  In the above embodiment, the frame-side reinforcing member 20 and the heel-side reinforcing member 27 are made of non-flammable metal. However, non-flammable metals such as iron and stainless steel, of course, have their surfaces first caused by a fire. The reinforcing member may be made of a flame retardant material such as MDF, wood, or the like, which is carbonized and delays the internal combustion due to the heat insulating effect of the carbonized surface.

  Moreover, although the relay member 22, the hanging metal fitting 23, the hook metal fitting 36, and the engaging member 25 are made of non-combustible metal, it takes time to burn as well as non-combustible metal such as iron and stainless steel. You may comprise with a flame-retardant member.

  Moreover, in the said embodiment, the upper end part of the inner shoji 3 is accommodated in the indoor side groove part 11i which the upper frame 11 and the lower frame 12 which comprise the frame 10 have, and it moves to the direction where the inner shoji 3 is found, and outdoor Although the description has been given of the joinery 1 in which the upper end portion of the external obstacle 4 is accommodated in the side groove portion 11j and moves in the direction in which the external obstacle 4 is found, the present invention is not limited thereto. For example, as shown in FIG. 13, the upper frame 110 and the lower frame 120 are integrated with the upper side grooves 35 g and 45 g provided in the upper collars 31 and 41 and the lower collars 32 and 42 of the inner and outer children 3 and 4. It may be a fitting 100 into which the provided rail 150 is inserted.
