And inner casing materials 21b and 22b made of resin-made extruded members.

  Both the outer flange portions 21a and 22a have flange hollow portions 21c and 22c penetrating in the longitudinal direction. Each of the flange hollow portions 21c and 22c is made of iron over the entire length and has a cross-sectional shape along the longitudinal direction. A U-shaped reinforcing member 31 is provided.

  In the reinforcing member 31, opposing wall portions 31a facing the U-shaped reinforcing member 31 are located on the outer peripheral side and the inner peripheral side of the casing 23 in each of the flange hollow parts 21c and 22c, respectively. , 22c is provided with a connecting wall portion 31b connecting the opposing wall portion 31a to the outdoor side. Further, on the connecting wall portion 31 b of each reinforcing member 31, a thermally expandable graphite 38 is provided on the indoor side surface over the entire length of the reinforcing member 31.

  Among the reinforcing members 31 provided in the pair of vertical hollows 21 and the vertical hollow pair 21 of the vertical hollows 21c and 22c, the reinforcing members 31 provided in the vertical hollows 21c of the pair of vertical rods 21 are illustrated in FIG. As shown in FIGS. 3 to 5, one opposing wall portion 31 a of the pair of opposing wall portions 31 a facing each other protrudes from the connecting wall portion 31 b toward the upper frame 11 or the lower frame 12 and is connected to the connecting wall portion.

That is, the surface 31d of the bent portion 31a provided on the reinforcing member 31 facing the outside of each vertical rod 21 faces the frame body 10 in a state where the door 20 closes the opening formed by the frame body 10. The heat-expandable graphite 38 provided on the surface 31d facing the outside of each vertical gutter 21 is on the upper end side and the lower end side of the vertical gutter hollow portion 21c of each vertical gutter 21 and on each small edge 21h side. It is provided so that it can bulge out. That is, the heat-expandable graphite 38 is provided so as to be able to swell toward the frame facing the upper end side and the lower end side of each vertical gutter 21.

  The pair of vertical gutters 21 and the upper and lower horizontal gutters 22 project from the outdoor side of each outer gutter part 21a, 22a and the inner side of each inner gutter material 21b, 22b to the inner circumference side, respectively, and the outer circumference part of the multilayer glass 3 The outer casing inner peripheral protrusions 21e and 22e and the inner casing inner peripheral protrusions 21f and 22f are formed.

  The outer peripheral surface 21g of the door 20 that faces the inner peripheral surfaces 11d, 12d, and 13d of the frame 20 in the housing portions 21d and 22d of the pair of vertical and lower horizontal rods 21 and 22 and the door 20 closed. , 22 g are provided with a thermal expansion graphite 38 that is heated and foamed over the entire length.

  Caps 25 made of synthetic resin are fitted on the upper and lower ends of the pair of vertical rods 21 to cover the small openings 21h of the pair of vertical rods 21, respectively. The cap 25 is close to the thermally expandable graphite 38 provided in the bent portion 31c of the reinforcing member 31 provided in each vertical gutter 21 in a state where the cap 25 is fitted to each vertical gutter 21, and the adjacent heat is applied. A communication hole 25 a that communicates the inside and outside of the hollow portion 21 c is provided in a portion facing the expandable graphite 38. For this reason, when exposed to a flame or the like, the thermally expandable graphite 38 is heated by the flame or hot air entering from the communication hole 25a, and swells out of the communication hole 25a.

  According to the door 20 of the present embodiment, the upper end portion side in the hollow portion 21c of the pair of vertical rods 21 that form the door rod and the hanging rod that the small opening 21h is opened in the frame 23 that is assembled. The thermally expandable graphite 38 provided on each of the lower end sides can bulge toward the upper frame 11 or the lower frame 12 facing each other. For this reason, when the vicinity of the small mouth 21h of the pair of vertical gutters 21 is heated by a flame or the like, the thermally expandable graphite 38 swells toward the small gutter 21h. It is possible to prevent the occurrence of a gap between the frame 20 and the frame body 10 that communicates indoors and outdoors and serves as an entrance for flames and hot air. Further, since the thermally expandable graphite 38 is provided in the hollow portion 21c of the pair of vertical rods 21 and on the upper end side and the lower end side, the thermally expandable graphite 38 is not exposed to the outside. It is possible to prevent a flame or the like from entering in the vicinity of the small mouth 21h. Therefore, it is possible to prevent melting of the downside 21 from the small edge 21h side without impairing the design.

  Moreover, since it has the cap 25 which covers the small edge 21h of the vertical gutter 21, the designability improves by covering the edge of the vertical gutter 21. Further, since the cap 25 is provided with a communication hole 25a communicating with the inside and outside of the hollow portion 21c in a portion facing the thermally expandable graphite 38, a flame or the like directly heats the thermally expandable graphite 38. Therefore, it is possible to swell the thermally expandable graphite 38 faster and more reliably.

  In the above embodiment, the thermally expandable graphite 38 is provided on the upper end side and the lower end side in the hollow portion 21c of the pair of vertical rods 21 so as to be able to bulge toward the opposed upper frame 11 or lower frame 12. However, it may be provided only on the lower end side that is more easily exposed to the flame. And since the door-end fence is more likely to warp due to heat compared to the suspension fence supported by the frame, when heated, the upper end moves to a position where it does not face the upper frame, and the lower end is the lower frame 12. It is easy to move to a position that does not oppose. For this reason, among the four ends of the pair of vertical gutters 21, the thermally expandable graphite 38 that can bulge toward the small edge 21 h side is provided on the upper end side and the lower end side of the door-end fence that is more easily melted by the flame. It may be provided or only on the lower end side where the gap is most likely to occur.

  Further, since the heat-expandable graphite 38 is provided in the iron reinforcing member 31 provided in the hollow portion 21c of the vertical wall 21, even if it is exposed to a flame or the like, the heat-expandable graphite 38 is The thermally expandable graphite 38 can stay together with the reinforcing member 31 without dropping off.

  According to the joinery 1 of the present embodiment having the frame body 10 that rotatably supports the door 20, the fire resistance is excellent in design and can prevent melting from the small edge 21 h side of the vertical gutter 21. It is possible to provide the joinery 1 having the door 20 provided.

  In the said embodiment, although the example in which the thermally expansible graphite 38 was provided in the bending part 31c of the reinforcement member 31 provided in the collar hollow part 21c of a pair of vertical collar 21 was demonstrated, it does not restrict to this. For example, as shown in FIG. 6, the reinforcing member 32 includes an iron main body member 33 having a U-shaped cross section, and an iron mounting member 35 screwed to the main body member 33 and having an L shape. In addition, a thermally expandable graphite 38 may be provided on a surface (opposing portion) 35a of the mounting member 35 that is screwed and faces the vertical rod 21. In this case, since the heat-expandable graphite 38 is provided on the reinforcing member 32 composed of the iron main body member 33 and the iron attachment member 35, the heat-expandable graphite 38 is exposed even if exposed to a flame or the like. The thermally expandable graphite 38 can remain on the mounting member 35 of the reinforcing member 32 without falling off. In addition, since the heat-expandable graphite 38 is provided on the mounting member 35 that is screwed to the main body member 33, the main body member 33 and the mounting member 35 can be formed in a simpler shape, thereby improving productivity.

  In the above embodiment, the reinforcing members 30, 31 and the main body member 33 of the reinforcing member 32 are made of non-flammable iron. However, non-flammable metals such as stainless steel, of course, are first caused by fire. The reinforcing member may be made of a flame retardant material such as MDF, wood, etc., which is carbonized and delays the internal combustion due to the heat insulating effect of the carbonized surface.

  Although the mounting member 35 is made of non-flammable iron, it may be composed of a non-flammable metal such as stainless steel or a flame-retardant block-like member that takes a long time to burn. .

  In the above-described embodiment, a pair of upper and lower horizontal bars 22 are interposed between the pair of vertical bars 21 at the upper and lower ends of the pair of vertical bars 21, and the pair of vertical bars 21 serves as a pair of horizontal planes. Although the case 23 has been described by taking the case 23 with its forehead closed as an example, a pair of left and right vertical folds are interposed between the pair of horizontal ridges at the left and right ends of the pair of horizontal ridges. It may be a frame in which the fore ends of a pair of vertical gutters are closed by a horizontal gutter. In this case, the reinforcing member provided in the hollow portion of the pair of reeds is provided with a facing portion facing the frame body in a state where the door closes the opening, and the thermally expanding graphite is provided in the facing portion. Is provided.

  In the above embodiment, the heat-expandable refractory material is the heat-expandable graphite 38. However, the heat-expandable graphite 38 is not limited to the heat-expandable graphite 38 as long as it is heated and expands.

  In the above-described embodiment, the example using the multilayer glass 3 has been described. However, it may be a single glass plate, and three or more glass plates are opposed to each other with a space therebetween, and are integrally formed. It may be a glass material. Moreover, the member fitted in the housing 23 is not limited to glass, and may be a plate-shaped interior material or exterior material. Not only the configuration in which the glass plate is incorporated in the housing part, but also a ventilation unit that incorporates a raising and lowering window unit in which two shojis are slidably arranged in the vertical direction in the housing part of the housing part that is assembled from four sides. It may be a door, or a configuration in which an opening shoji is incorporated in the unit housing.

  In the above-described embodiment, the vertical rod 21 and the upper and lower horizontal rods 22 are both arranged on the outdoor side and are made of an aluminum extrusion molding member 21a, 22a, and the indoor side of the outer flange portions 21a, 22a. However, the present invention is not limited to this configuration, and the outdoor side may be made of synthetic resin and the indoor side may be made of aluminum, or may have a large hollow portion. Even if the vertical gutter 21 and the upper and lower horizontal gutters are not configured by combining the outer side outer gutter part and the indoor side inner gutter part, the vertical gutter 21 and the upper and lower horizontal gutters are formed only by the outer gutter part having a large hollow part. A bag may be formed, and at that time, it may be formed of aluminum or synthetic resin.
