Since the position where the member 25 is fixed is the outer peripheral side from the inner peripheral surface 5a of the frame 5, the portion where the engaging member 25 is fixed by the frame 5 is difficult to be heated. For this reason, even if the right frame 14 in which the frame side reinforcing member 20 is not provided in the central hollow portion 14k is exposed to the flame from the indoor side, it is possible to prevent melting and burning in a short time.

  The upper frame 11, the lower frame 12, and the left frame 13 in which the frame-side reinforcing member 20 is provided in the central hollow portions 11k, 12k, and 13k are each made of a non-combustible material. Since it is connected by the iron connection fitting 21, the upper frame 11, the lower frame 12, and the left frame 13 provided with the frame-side reinforcing member 20 are held by the housing 2 even when exposed to a flame. It is possible to prevent the frame 10 from coming off in a short time.

  Also, the door rods 33 and 43 of the inner and outer children 3 and 4 have flange-side groove portions 35g and 45g into which the engaging members 25 are inserted, and the outdoor groove portion 13j of the left frame 13 and the door of the outer door child 4. In the region surrounded by the heel side groove portion 45g of the leading edge 43, and in the region surrounded by the heel side groove portion 35g of the indoor side groove portion 11i of the right frame 14 and the door edge rod 33 of the shoji 3 Is provided with thermally expandable graphite 38 which is heated and foamed. For this reason, when the joinery 1 is exposed to a flame or the like and heated, the interior side groove of the right frame 14 and the region surrounded by the outdoor side groove 13j of the left frame 13 and the heel side groove 45g of the shoji 4 Since the thermally expandable graphite 38 is foamed in the region surrounded by the portion 11i and the heel side groove portion 35g of the inner impeller 3, even if the frame body 10 and the housing 45 are melted, the heat foamed inside Since the expandable graphite 38 is filled, it is possible to prevent a gap penetrating the room from occurring.

  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.

  In the said embodiment, although the example which was made into the laminated glass 7 which formed two sheet glass facing each other with the space | interval spaced apart from each other was demonstrated, the face material is one glass plate, Alternatively, it may be a multi-layer glass in which three or more sheet glasses face each other at an interval and are integrally formed. Further, the face material is not limited to glass, and may be a plate-like interior material or exterior material. Further, the frame body may not be provided with a face material, for example, a frame body constituting a panel material.

  In addition, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention.
