尚、戸先側竪枠１３ａと上枠９の突き合せ部８との間の空間は、第５熱膨張耐火材３２ｅが塞ぎ、吊り元側竪枠１３ｂと上枠９の突き合せ部８との間の空間は第６熱膨張耐火材３２ｆが塞ぐ。
図２、図３及び図１０に示すように、各竪枠１３ａ、１３ｂの上端部と下端部とに設けた中空部取付金具４４は、下枠１９との対向面及び上枠９との対向面に第７熱膨張耐火材３２ｇを設けているので、火災時に各竪枠１３ａ、１３ｂとコーナーを形成する下枠１１及び上枠９との間を塞ぎ、各竪枠１３ａ、１３ｂと下枠１１及び上枠９とのコーナー部から火炎が噴出するのを防止できる。
図１０（ｄ）に示すように、中空部取付金具４４の室内側見付面に設けた第８熱膨張耐火材３２ｈは、火災時に膨張して、竪枠１３ａ、１３ｂの各上端部と下端部に各々設けた横不燃タイト材３５の呑み込み用切除部６９を塞ぐ。 Next, the effect of the fitting 1 concerning 1st Embodiment is demonstrated.
As shown in FIG. 3, in the lower door tip side mounting bracket 41, as described above, at the portion where the third thermal expansion refractory material 32c provided on the side surface of the shoji is expanded in the event of a fire and there is no fifth thermal expansion refractory material 32e. In addition to closing the space between the side wall frame 13a and the door end side wall 21a, as shown in FIGS. 9 and 11, the fourth thermal expansion refractory material 32d provided on the side surface of the frame expands, and the upper frame 11 The butt portion 8 of the fore edge where the wall portion 11c is cut off and the fore edge of the port side frame 13a of the port side frame 13a are closed to prevent the flame from blowing out from the butt portion 8 and the port side frame 13a. The gap between the small opening from which the indoor side finding wall 10 is cut off and the recess 11b of the lower frame 11 is closed. Moreover, since the lower door end side mounting bracket 41 is arranged with the finding surface portion 41 overlapped with the butt portion 8, the butt portion 8 can be reinforced.
In addition, the space between the door-end side frame 13a and the abutting portion 8 of the upper frame 9 is closed by the fifth thermal expansion refractory material 32e, and the suspension-side side frame 13b and the abutting portion 8 of the upper frame 9 The space between the sixth thermal expansion refractory material 32f is closed.
As shown in FIGS. 2, 3, and 10, the hollow portion mounting brackets 44 provided at the upper and lower ends of the flange frames 13 a and 13 b are opposed to the lower frame 19 and the upper frame 9. Since the surface is provided with the seventh thermal expansion refractory material 32g, in the event of a fire, the space between each frame 13a, 13b and the lower frame 11 and the upper frame 9 forming the corner is closed, and each frame 13a, 13b and the lower frame It is possible to prevent the flame from being ejected from the corner portions 11 and the upper frame 9.

図１及び図２に示すように、下枠１１の上面に設けた障子受け６は、通常時には障子５は障子受け６との間に隙間をあけているので、障子５を開閉するときに邪魔にならない。
火災時に、火災の熱により、例えば障子支持具７の樹脂製部分が溶融することにより、障子５が下がると下枠１１の上面から上方に突設している障子載置部６ａに障子５を載置することにより、障子５が大きく下がって脱落するのを防止する。また、障子５を障子載置部６ａに載置して支持することにより、障子５が大きく下がって枠３との間に大きな隙間が生じるのを防止できる。
障子受け６は下枠１１の上面から突設して、障子下框１９との間の間隔を狭めているので、火災時に障子下端からの通気を抑制できる。
また、火災時の熱を受けると障子受け６に設けた第１熱膨張耐火材３２ａが膨張することで、障子５の下端との隙間を塞ぎ、障子下側から室外側へ火炎が噴出するのを防止できる。 As shown in FIGS. 1 and 2, the shoji receiver 6 provided on the upper surface of the lower frame 11 normally has a gap between the shoji 5 and the shoji receiver 6. do not become.
In the event of a fire, for example, when the shoji 5 is lowered by melting the resin portion of the shoji support 7 due to the heat of the fire, the shoji 5 is placed on the shoji placement portion 6a protruding upward from the upper surface of the lower frame 11. By placing it, the shoji 5 is prevented from greatly falling and falling off. In addition, by placing the shoji 5 on the shoji placement portion 6a and supporting it, it is possible to prevent the shoji 5 from being greatly lowered and generating a large gap with the frame 3.
Since the shoji receiver 6 protrudes from the upper surface of the lower frame 11 and narrows the space between the shoji lower arm 19, the ventilation from the lower end of the shoji can be suppressed during a fire.
Moreover, when the heat at the time of a fire is received, the 1st thermal expansion refractory material 32a provided in the shoji receiver 6 will expand, and the gap with the lower end of the shoji 5 will be closed, and a flame will eject from the shoji underside to the outdoor side. Can be prevented.

特に、火災時には竪枠１３ａが熱伸びにして反りが生じることにより、竪枠１３ａと下枠１１の各突き合わせ部８ａ、８ｂ、８ｃに隙間が生じても、かかる隙間を塞ぐことができる。
図１２及び図１３に示すように、障子５には、上框１７、下框１９及び左右の框２１ａ、２１ｂに設けた各ガラス保持溝補強材５３に第１７熱膨張耐火材３２ｒが設けてあるから、火災時に各框１７、１９、２１ａ、２１ｂとガラス４との間を塞ぎ、ガラス４の四周で室内と室外が連通して火炎や煙が室内側に入り込んだり、室内側から噴出するのを防止できる。
また、下框１９にはガラス保持溝補強材５３の上にアルミニウム製のセッティングブロック７１を設けているので、火災時にグレイジングガスケット４９が溶融してもガラス４が下がるのを阻止してガラス４を安定に保持できる。 According to the second embodiment, as shown in FIG. 15 (b), the hollow portion mounting bracket 44 provided at the lower end portion of the collar frame 13 a is formed on the lateral frame side surface 44 a that faces the prospective surface 11 f of the lower frame 11. Since the seventh thermal expansion refractory material 32g is provided, when the seventh thermal expansion refractory material 32g expands in the event of a fire, between the lower side of the hollow portion mounting bracket 44 and the upper surface of the lower frame 11 in the hollow portion 12. Thereby, the abutting portions 8a, 8b, 8c of the lower frame 11 and the hollow portion 12 of the port side frame 13a, the outdoor small opening 12c of the inner peripheral wall 12b of the hollow portion 12, and the lateral chamber of the lower frame 11 Since the space P of the outer side finding wall 10b can be blocked, it is possible to prevent the flames and smoke from being ejected from the butted portions 8a, 8b, 8c and the space P. In addition, since the 14th thermal expansion refractory material 32m provided in the lower frame 11 has entered the inside of the hollow portion 12, the seventh thermal expansion refractory material 32g is in contact with each other by thermal expansion in the hollow portion 12 during a fire. It assists to block the portions 8a, 8b, 8c and the space P.
In particular, even when a gap occurs in the butted portions 8a, 8b, and 8c of the saddle frame 13a and the lower frame 11 due to the warp frame 13a being warped due to thermal expansion during a fire, the gap can be blocked.
As shown in FIGS. 12 and 13, the shoji 5 is provided with a seventeenth thermal expansion refractory material 32 r on each glass holding groove reinforcing material 53 provided on the upper heel 17, the lower heel 19, and the left and right ridges 21 a, 21 b. Therefore, in the event of a fire, the space between each fence 17, 19, 21a, 21b and the glass 4 is closed, and the interior and exterior of the glass 4 communicate with each other around the glass 4 so that flames and smoke enter the indoor side, or blow out from the indoor side. Can be prevented.
In addition, since the setting rod 71 made of aluminum is provided on the glass holding groove reinforcing material 53 in the lower rod 19, the glass 4 is prevented from lowering even if the glazing gasket 49 is melted in a fire. Can be kept stable.
