しかしながら、このような戸においては、火災時に枠体及びガラスパネルが脱落して室内外が連通し、火炎や煙が通過して延焼に繋がるおそれがあった。 However, in such a door, there was a risk that the frame and the glass panel dropped off during a fire, the interior and the exterior communicated, and flames and smoke passed, leading to fire spread.

本発明は、上記事情を鑑みたものであり、窓を有し、炎熱にさらされても窓のガラスパネルが脱落しない戸を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a door that has a window and does not drop off the glass panel of the window even when exposed to flame heat.

本発明は、戸本体と、ガラスパネルと、一方枠体と、他方枠体を備え、戸本体は、一方側面と他方側面の両面に耐火性パネルを取り付けてあって、一方側と他方側を連通する開口部を設けてあり、一方側面の耐火性パネルが、開口部の内周側に延出する延出部を有しており、開口部にガラスパネルを嵌め込んであって、一方枠体と他方枠体でガラスパネルを挟み込んで保持しており、他方枠体が、一方側に向けて延びるネジ止め部を有していて、一方枠体と、他方枠体のネジ止め部によって、一方側面の耐火性パネルの延出部を挟み込んでネジ止めしてあることを特徴とする。 The present invention includes a door main body, a glass panel, one frame, and the other frame, and the door main body has fireproof panels attached to both the one side surface and the other side surface, and the one side and the other side are arranged. A communicating opening is provided, the fireproof panel on one side has an extending part extending to the inner peripheral side of the opening, and a glass panel is fitted into the opening, The glass panel is sandwiched and held between the body and the other frame body, the other frame body has a screwing portion extending toward one side, and the one frame body and the screwing portion of the other frame body, On the other hand, the extension part of the fireproof panel on the side is sandwiched and screwed.

本発明によれば、戸の一方側で火災が発生した場合、一方枠体が溶解・脱落しても、一方側面の耐火性パネルの延出部にネジ止めした他方枠体は脱落しない。また、戸の他方側で火災が発生した場合、他方枠体の他方側の露出部分が溶解しても、他方枠体のネジ止め部の少なくとも一部は溶解せずに残存し、ネジ止め部とともに一方側面の耐火性パネルの延出部を挟み込んでネジ止めした一方枠体は脱落しない。よって、何れの場合においても、火災が発生した側の反対側の枠体は、脱落せず維持される。そして、一般に火災が発生した側は正圧となり、ガラスパネルは残った枠体に押圧されて脱落しないので、一方側と他方側とが連通しない。これにより、火炎や煙が遮断され、延焼が防がれる。 According to the present invention, when a fire occurs on one side of the door, even if one frame is melted / dropped, the other frame that is screwed to the extending portion of the fireproof panel on one side does not drop. Also, when a fire occurs on the other side of the door, even if the exposed part of the other side of the other frame is dissolved, at least a part of the screwed part of the other frame remains undissolved, and the screwed part At the same time, the one frame body that is screwed by sandwiching the extending portion of the fireproof panel on one side does not fall off. Therefore, in any case, the frame on the side opposite to the side where the fire has occurred is maintained without dropping. In general, the side where the fire has occurred becomes positive pressure, and the glass panel is pressed by the remaining frame and does not fall off, so that one side does not communicate with the other side. Thereby, a flame and smoke are interrupted | blocked and a fire spread is prevented.

More specifically, the opening 11 is formed of a square hole formed in the door main body 1 and the fireproof panels 5a and 5b on both sides thereof, and communicates the indoor side (one side) and the outdoor side (the other side). . However, as shown in FIG. 1, the hole of the fireproof panel 5a on the indoor side (one side) is smaller than the hole of the fireproof panel 5b on the door body 1 and the outdoor side (the other side), that is, the indoor side ( The fireproof panel 5 a on the one side has an extension 51 that extends to the inner peripheral side of the opening 11. In addition, as shown in FIGS. 1-3, the refractory material 6 is provided between the door main body 1 and the refractory panels 5a and 5b over the perimeter of the periphery of the opening part 11. As shown in FIG. The refractory material 6 expands by foaming due to heat during a fire, and is normally crushed between the door body 1 and the refractory panels 5a and 5b. The glass panel 2 is a multi-layer glass in which a spacer 22 is sandwiched between two heat-resistant glass plates 21a and 21b. In particular, the indoor glass plate 21a is made of netted glass.

一方枠体３は、アルミ鋳物からなるものであって、図４に示すように、正方形の枠体形状のものであり、（ａ）に示す正面が室内側（一方側）を向き、（ｃ）に示す背面が室外側（他方側）、すなわちガラスパネル２側を向く。大きさは、戸本体１の開口部１１よりも一回り大きい。そして、上下左右の各辺において、室内側面の内周部及び外周部は、意匠性を考慮して、それぞれ内周側及び外周側へ向けて室外側に傾斜した形状となっている。また、各辺の中央部には、室内外方向に貫通するネジ孔３１を設けてある。さらに、各辺の室外側面の内周部には、室外側に向けて開口する溝部３２を形成してある。 On the other hand, the frame 3 is made of an aluminum casting and has a square frame shape as shown in FIG. 4, and the front side shown in (a) faces the indoor side (one side), (c ) Is directed to the outdoor side (the other side), that is, the glass panel 2 side. The size is slightly larger than the opening 11 of the door body 1. Then, in each of the upper, lower, left and right sides, the inner peripheral portion and the outer peripheral portion of the indoor side surface are inclined toward the inner peripheral side and the outer peripheral side, respectively, in consideration of design. Moreover, the screw hole 31 penetrated in the indoor / outdoor direction is provided in the central part of each side. Furthermore, the groove part 32 opened toward the outdoor side is formed in the inner peripheral part of the outdoor side surface of each side.

他方枠体４は、アルミ鋳物からなるものであって、図５に示すように、正方形の枠体形状のものであり、（ａ）に示す正面が室外側（他方側）を向き、（ｃ）に示す背面が室内側（一方側）、すなわちガラスパネル２側を向く。大きさは、戸本体１の開口部１１よりも一回り大きく、一方枠体３と略同じである。上下左右の各辺において、室外側面は、意匠性を考慮して、外周側から内周側へ向けて室内側に傾斜した形状となっている。また、各辺の室内側面の中央部には、室内側（一方側）に向けて延びるネジ止め部４１を形成してある。ネジ止め部４１は、室内側に向けて先細となる四角錐台形状であって、他方枠体４の各辺の略１／５の幅であり、延出長さは戸本体１の厚さと略同じである。そして、ネジ止め部４１の先端面（室内側面）には雌ネジ部４２が形成してあり、この雌ネジ部４２の位置は、一方枠体３と組み合わせた際に、ネジ孔３１の位置と重なる。さらに、各辺の室内側面の内周部には、室内側に向けて開口する溝部４３を形成してある。また、室外側面には、上下及び左右に延びる格子材４４を二本ずつ設けて井桁状に形成してある。 The other frame 4 is made of an aluminum casting and has a square frame shape as shown in FIG. 5, and the front surface shown in (a) faces the outdoor side (the other side), (c ) Is directed to the indoor side (one side), that is, the glass panel 2 side. The size is slightly larger than the opening 11 of the door body 1 and is substantially the same as the frame 3. In each of the upper, lower, left, and right sides, the outdoor side surface has a shape inclined toward the indoor side from the outer peripheral side toward the inner peripheral side in consideration of design. Moreover, the screwing part 41 extended toward the indoor side (one side) is formed in the center part of the indoor side surface of each side. The screwing portion 41 has a quadrangular frustum shape that tapers toward the indoor side, has a width that is approximately 1/5 of each side of the other frame body 4, and the extension length is equal to the thickness of the door body 1. It is almost the same. A female screw portion 42 is formed on the tip surface (inner side surface) of the screwing portion 41, and the position of the female screw portion 42 is the same as the position of the screw hole 31 when combined with the one frame 3. Overlap. Furthermore, the groove part 43 opened toward the indoor side is formed in the inner peripheral part of the indoor side surface of each side. Further, two grid members 44 extending in the vertical and horizontal directions are provided on the outdoor side surface to form a cross beam.

そして、このように形成した一方枠体３及び他方枠体４によって、ガラスパネル２を挟み込む。それには、図１に示すように、まず一方枠体３の溝部３２と他方枠体４の溝部４３に、それぞれタイト材３３，４５を嵌め込んで取り付ける。そして、他方枠体４を戸本体１の開口部１１に室外側（他方側）から取り付け、ガラスパネル２を室内側（一方側）から開口部１１に嵌め込む。この際、図２に示すように、他方枠体４の下辺のネジ止め部４１の上面にセッティングブロック２３を取り付け、セッティングブロック２３にガラスパネル２を載置する（このため、他方枠体４の下辺のネジ止め部４１の上面は水平向きになっている）。そして一方枠体３を開口部１１に室内側（一方側）から取り付けることで、一方枠体３のタイト材３３と他方枠体４のタイト材４５により、ガラスパネル２が挟み込まれる。ここで、一方枠体３と他方枠体４は、何れも開口部１１より一回り大きいので、一方枠体３と他方枠体４の外周部が、開口部１１の周縁部に係合するものであり、すなわち、一方枠体３の外周部の室外側面が、室内側の耐火性パネル５ａ及び内周側に延出する延出部５１に当接し、他方枠体４の外周部の室内側面が、室外側の耐火性パネル５ｂに当接する。そして、他方枠体４のネジ止め部４１は、ガラスパネル２の外周側（戸本体１とガラスパネル２の間）に位置し、先端面（室内側面）が、室内側（一方側）の耐火性パネル５ａの延出部５１に当接する。よって、室内側（一方側）の耐火性パネル５ａの延出部５１は、一方枠体３と、他方枠体４のネジ止め部４１によって挟み込まれる。延出部５１には、一方枠体３のネジ孔３１及び他方枠体４の雌ネジ部４２と重なる位置に貫通孔を形成してあり、貫通孔を通して、一方枠体３のネジ孔３１と他方枠体４の雌ネジ部４２が連通する。そして、一方枠体３の四つのネジ孔３１からそれぞれネジ７を挿入し、雌ネジ部４２に螺合させることで、一方枠体３と他方枠体４がネジ止めされる。ネジ孔３１には、室内側からキャップ３４を被せて、ネジ７を覆い隠してある。また、一方枠体３の室外側面のネジ孔３１と溝部３２の間及び他方枠体４の室内側面のネジ止め部４１と溝部４３の間には、それぞれ四周にわたって延びる耐火材８を取り付けてあり、一方枠体３の耐火材８と他方枠体４の耐火材８が対向している。この耐火材８は、火災時において、熱により発泡して膨張するものである。また、図２に示すように、開口部１１の下辺において、戸本体１の内周側面を防水シート１５で覆ってある。防水シート１５は、室内側端において、耐火性パネル５ａの延出部５１との隙間をシール材１６により埋めてあり、室外側端において、戸の室外側面に折り返してあって、他方枠体４と耐火性パネル５ｂの間に挟み込まれている。この防水シート１５により、戸本体１と耐火性パネル５ａ，５ｂの間に水が浸入することを防いでいる。 And the glass panel 2 is inserted | pinched by the one frame 3 and the other frame 4 which were formed in this way. For this purpose, as shown in FIG. 1, first, tight materials 33 and 45 are fitted and attached to the groove 32 of the one frame 3 and the groove 43 of the other frame 4, respectively. Then, the other frame body 4 is attached to the opening 11 of the door body 1 from the outdoor side (the other side), and the glass panel 2 is fitted into the opening 11 from the indoor side (the one side). At this time, as shown in FIG. 2, the setting block 23 is attached to the upper surface of the screwing portion 41 on the lower side of the other frame 4, and the glass panel 2 is placed on the setting block 23 (for this reason, the other frame 4 The upper surface of the screwing portion 41 on the lower side is horizontally oriented). And the glass panel 2 is inserted | pinched by the tight material 33 of the one frame 3, and the tight material 45 of the other frame 4 by attaching the one frame 3 to the opening part 11 from the indoor side (one side). Here, since the one frame body 3 and the other frame body 4 are both slightly larger than the opening portion 11, the outer peripheral portions of the one frame body 3 and the other frame body 4 are engaged with the peripheral edge portion of the opening portion 11. That is, the outdoor side surface of the outer peripheral portion of the one frame body 3 is in contact with the fireproof panel 5a on the indoor side and the extending portion 51 extending to the inner peripheral side, and the indoor side surface of the outer peripheral portion of the other frame body 4 is However, it contacts the fireproof panel 5b on the outdoor side. And the screwing part 41 of the other frame 4 is located in the outer peripheral side (between the door main body 1 and the glass panel 2) of the glass panel 2, and a front end surface (interior side) is fireproof of the indoor side (one side). The abutting portion 51 of the conductive panel 5a. Therefore, the extension part 51 of the fireproof panel 5 a on the indoor side (one side) is sandwiched between the one frame body 3 and the screwing part 41 of the other frame body 4. A through hole is formed in the extending portion 51 at a position overlapping the screw hole 31 of the one frame body 3 and the female screw portion 42 of the other frame body 4, and the screw hole 31 of the one frame body 3 passes through the through hole. The female screw portion 42 of the other frame body 4 communicates. Then, by inserting the screws 7 from the four screw holes 31 of the one frame body 3 and screwing them into the female screw portion 42, the one frame body 3 and the other frame body 4 are screwed. The screw hole 31 is covered with a cap 34 from the indoor side to cover the screw 7. In addition, a refractory material 8 extending over four circumferences is attached between the screw hole 31 and the groove 32 on the outdoor side surface of the one frame 3 and between the screwing portion 41 and the groove 43 on the indoor side surface of the other frame 4. The refractory material 8 of the one frame 3 and the refractory material 8 of the other frame 4 face each other. The refractory material 8 expands by foaming due to heat during a fire. As shown in FIG. 2, the inner peripheral side surface of the door body 1 is covered with a waterproof sheet 15 at the lower side of the opening 11. The waterproof sheet 15 is filled with a seal material 16 at the indoor side end with the extending portion 51 of the fireproof panel 5a, and is folded back to the outdoor side surface of the door at the outdoor side end. And the fireproof panel 5b. The waterproof sheet 15 prevents water from entering between the door body 1 and the fireproof panels 5a and 5b.

このように構成した戸の第一実施形態によれば、戸の室内側（一方側）で火災が発生した場合、一方枠体３が溶解・脱落しても、他方枠体４は溶解せず、ネジ止め部４１にネジが掛かった状態が維持され、室内側（一方側）の耐火性パネル５ａの延出部５１にネジ止めした他方枠体４は脱落しない。また、戸の室外側（他方側）で火災が発生した場合、他方枠体４の室外側（他方側）の露出部分が溶解しても、他方枠体４のネジ止め部４１は、開口部１１内に奥まっており、また一方枠体３に取り付けた耐火材８が熱により発泡してネジ止め部４１の内周側面を覆うため、少なくとも一部は溶解せずに残存する。これにより、残存したネジ止め部４１にネジが掛かった状態が維持され、ネジ止め部４１とともに室内側（一方側）の耐火性パネル５ａの延出部５１を挟み込んでネジ止めした一方枠体３は脱落しない。よって、何れの場合においても、火災が発生した側の反対側の枠体は、脱落せず維持される。そして、一般に火災が発生した側は正圧となり、ガラスパネル２は残った枠体に押圧され、さらにガラスパネル２はセッティングブロック２３を介して他方枠体４の下辺のネジ止め部４１に載置されているので、ガラスパネル２が脱落することはなく、開口部１１において室内側と室外側とが連通しない。このようにして、本発明の戸により火炎や煙が遮断され、延焼が防がれる。さらに、火災時には、少なくとも残った枠体の耐火材８が熱により発泡して膨張し、ガラスパネル２の周縁部と他方枠体４のネジ止め部４１の間の空間に充満するので、気密が維持され、より確実に火炎や煙が遮断される。また、火災時には、耐火性パネル５ａ，５ｂを接着している接着剤が溶解して、戸本体１から耐火性パネル５ａ，５ｂが浮き上がる場合があるが、その際には、戸本体１と耐火性パネル５ａ，５ｂの間に設けた耐火材６が発泡して、戸本体１と耐火性パネル５ａ，５ｂの間に炎熱が進入することを防ぐ。 According to the first embodiment of the door configured as described above, when a fire occurs on the indoor side (one side) of the door, even if one frame body 3 is dissolved and dropped, the other frame body 4 is not dissolved. The state where the screwing portion 41 is screwed is maintained, and the other frame body 4 screwed to the extending portion 51 of the fireproof panel 5a on the indoor side (one side) does not fall off. In addition, when a fire occurs on the outdoor side (the other side) of the door, even if the exposed part on the outdoor side (the other side) of the other frame 4 is dissolved, 11, and the refractory material 8 attached to the frame 3 foams by heat and covers the inner peripheral side surface of the screwing portion 41, so that at least a part remains without being dissolved. As a result, the remaining screwed portion 41 is maintained in a screwed state, and the one frame 3 that is screwed by sandwiching the extended portion 51 of the fireproof panel 5a on the indoor side (one side) together with the screwed portion 41. Will not fall off. Therefore, in any case, the frame on the side opposite to the side where the fire has occurred is maintained without dropping. In general, the side where the fire has occurred becomes positive pressure, the glass panel 2 is pressed by the remaining frame, and the glass panel 2 is placed on the screwing portion 41 on the lower side of the other frame 4 through the setting block 23. Therefore, the glass panel 2 does not fall off, and the indoor side and the outdoor side do not communicate with each other in the opening 11. In this way, flames and smoke are blocked by the door of the present invention, and fire spread is prevented. Further, at the time of a fire, at least the remaining refractory material 8 of the frame body is foamed and expanded by heat, and fills the space between the peripheral edge portion of the glass panel 2 and the screwing portion 41 of the other frame body 4. Maintained and more reliably cut off flames and smoke. In addition, in the event of a fire, the adhesive that bonds the fireproof panels 5a and 5b may dissolve and the fireproof panels 5a and 5b may float from the door body 1. The refractory material 6 provided between the refractory panels 5a and 5b foams and prevents flame heat from entering between the door body 1 and the refractory panels 5a and 5b.

また、図７に示すのは、本発明の戸の第二実施形態の開口部１１の縁部の拡大図である。第二実施形態も、第一実施形態と同様に玄関戸として用いられるものであって、戸本体１に窓１０を設けてあり、窓１０は、戸本体１に形成した開口部１１に、ガラスパネル２を嵌め込み、室内側（一方側）と室外側（他方側）から、それぞれ一方枠体１０３と他方枠体１０４を取り付けて、両枠体１０３，１０４でガラスパネル２を挟み込んで保持したものである。ただし、第一実施形態と異なり、一方枠体１０３と他方枠体１０４が、アルミ形材により形成されている。 Moreover, what is shown in FIG. 7 is an enlarged view of the edge part of the opening part 11 of 2nd embodiment of the door of this invention. Similarly to the first embodiment, the second embodiment is also used as an entrance door, and is provided with a window 10 in the door body 1, and the window 10 is made of glass in an opening 11 formed in the door body 1. The panel 2 is fitted, and the one frame body 103 and the other frame body 104 are respectively attached from the indoor side (one side) and the outdoor side (the other side), and the glass panel 2 is sandwiched and held between the two frame bodies 103 and 104. It is. However, unlike the first embodiment, the one frame 103 and the other frame 104 are formed of an aluminum profile.

一方枠体１０３は、アルミ形材を四周枠組みして、正方形の枠体形状としたものであり、戸本体１の開口部１１よりも一回り大きい。そして、上下左右の各辺において、室内側（一方側）に向けて開口する略Ｃ字状の取付溝１３５を設けてあり、各辺の中央部の取付溝１３５の底面（見付面）には、室内外方向に貫通するネジ孔１３１を設けてある。また、各辺の内周部には、室外側に向けて突出する略Ｔ字状の係合部１３２を形成してある。 On the other hand, the frame body 103 is a square frame shape formed by four-frames of an aluminum shape, and is slightly larger than the opening 11 of the door body 1.

Is provided with a screw hole 131 penetrating in the indoor / outdoor direction. Further, a substantially T-shaped engaging portion 132 protruding toward the outdoor side is formed on the inner peripheral portion of each side.

他方枠体１０４は、アルミ形材を四周枠組みして、正方形の枠体形状としたものであり、戸本体１の開口部１１よりも一回り大きい。そして、上下左右の各辺が、断面略矩形の中空形材からなる。また、各辺の室内側面には、室内側（一方側）に向けて延びるネジ止め部１４１を形成してある。ネジ止め部１４１は、室内側に向けて延びる見込面部１４６と、見込面部１４６の室内側端から外周側に向けて延びる見付面部１４７からなる。そして、ネジ止め部１４１の見付面部１４７には雌ネジ部１４２が形成してあり、この雌ネジ部１４２の位置は、一方枠体１０３と組み合わせた際に、ネジ孔１３１の位置と重なる。さらに、各辺の室内側面の内周部には、室内側に向けて開口する略Ｃ字状の溝部１４３を形成してある。 On the other hand, the frame body 104 is a square frame shape obtained by making a four-frame frame of an aluminum profile, and is slightly larger than the opening 11 of the door body 1. Each of the upper, lower, left and right sides is made of a hollow material having a substantially rectangular cross section. Moreover, the screwing part 141 extended toward the indoor side (one side) is formed in the indoor side surface of each edge | side. The screwing portion 141 includes an expected surface portion 146 extending toward the indoor side, and a finding surface portion 147 extending from the indoor side end of the expected surface portion 146 toward the outer peripheral side. And the female thread part 142 is formed in the finding surface part 147 of the screwing part 141, The position of this female thread part 142 overlaps with the position of the screw hole 131 when it combines with the one frame 103. Furthermore, a substantially C-shaped groove portion 143 that opens toward the indoor side is formed on the inner peripheral portion of the indoor side surface of each side.

そして、このように形成した一方枠体１０３及び他方枠体１０４によって、ガラスパネル２を挟み込む。それには、図７に示すように、まず一方枠体１０３の係合部１３２と他方枠体１０４の溝部１４３に、それぞれタイト材１３３，１４５を取り付ける。そして、他方枠体１０４を戸本体１の開口部１１に室外側（他方側）から取り付け、ガラスパネル２を室内側（一方側）から開口部１１に嵌め込み、さらに一方枠体１０３を開口部１１に室内側（一方側）から取り付けることで、一方枠体１０３のタイト材１３３と他方枠体１０４のタイト材１４５により、ガラスパネル２が挟み込まれる。ここで、一方枠体１０３と他方枠体１０４は、何れも開口部１１より一回り大きいので、一方枠体１０３と他方枠体１０４の外周部が、開口部１１の周縁部に係合するものであり、すなわち、一方枠体１０３の外周部が、室内側の耐火性パネル５ａ及び内周側に延出する延出部５１に当接し、他方枠体１０４の外周部が、室外側の耐火性パネル５ｂに当接する。そして、他方枠体１０４のネジ止め部１４１は、ガラスパネル２の外周側（戸本体１とガラスパネル２の間）に位置し、見付面部１４７が、室内側（一方側）の耐火性パネル５ａの延出部５１に当接する。よって、室内側（一方側）の耐火性パネル５ａの延出部５１は、一方枠体１０３と、他方枠体１０４のネジ止め部１４１によって挟み込まれる。延出部５１には、一方枠体１０３のネジ孔１３１及び他方枠体１０４の雌ネジ部１４２と重なる位置に貫通孔を形成してあり、貫通孔を通して、一方枠体１０３のネジ孔１３１と他方枠体１０４の雌ネジ部１４２が連通する。そして、一方枠体１０３の四つのネジ孔１３１からそれぞれネジ７を挿入し、雌ネジ部１４２に螺合させることで、一方枠体１０３と他方枠体１０４がネジ止めされる。さらに、一方枠体１０３には、室内側からカバー材１３４を被せてある。カバー材１３４は、一方枠体１０３の取付溝１３５に係合させて取り付けるものであり、内周部及び外周部は、意匠性を考慮して、それぞれ内周側及び外周側へ向けて室外側に傾斜した形状となっていて、一方枠体１０３の全体を覆い隠してある。また、一方枠体１０３の室外側面のネジ孔１３１と係合部１３２の間、他方枠体１０４の室内側面の見込面部１４６の内周側部分と外周側部分及び見付面部１４７の室外側面には、それぞれ四周にわたって延びる耐火材８を取り付けてあり、室内側と室外側の耐火材８が対向している。この耐火材８は、火災時において、熱により発泡して膨張するものである。 And the glass panel 2 is inserted | pinched by the one frame 103 and the other frame 104 which were formed in this way. For this purpose, as shown in FIG. 7, first, tight materials 133 and 145 are respectively attached to the engaging portion 132 of the one frame 103 and the groove 143 of the other frame 104. Then, the other frame 104 is attached to the opening 11 of the door body 1 from the outdoor side (the other side), the glass panel 2 is fitted into the opening 11 from the indoor side (one side), and the one frame 103 is further opened to the opening 11. The glass panel 2 is sandwiched between the tight material 133 of the one frame body 103 and the tight material 145 of the other frame body 104 by being attached from the indoor side (one side). Here, since the one frame body 103 and the other frame body 104 are both slightly larger than the opening portion 11, the outer peripheral portions of the one frame body 103 and the other frame body 104 are engaged with the peripheral edge portion of the opening portion 11. That is, the outer peripheral portion of one frame 103 is in contact with the fireproof panel 5a on the indoor side and the extending portion 51 extending to the inner peripheral side, and the outer peripheral portion of the other frame 104 is fireproof on the outdoor side. The abutting panel 5b. And the screwing part 141 of the other frame 104 is located in the outer peripheral side (between the door main body 1 and the glass panel 2) of the glass panel 2, and the finding surface part 147 is a fireproof panel of the indoor side (one side). It contacts the extending portion 51 of 5a. Therefore, the extension part 51 of the fireproof panel 5a on the indoor side (one side) is sandwiched between the one frame body 103 and the screwing part 141 of the other frame body 104. A through hole is formed in the extending portion 51 at a position overlapping the screw hole 131 of the one frame body 103 and the female screw portion 142 of the other frame body 104, and the screw hole 131 of the one frame body 103 passes through the through hole. The female screw part 142 of the other frame body 104 communicates. Then, the screws 7 are inserted through the four screw holes 131 of the one frame 103 and screwed into the female screw portion 142, whereby the one frame 103 and the other frame 104 are screwed. Further, the one frame 103 is covered with a cover material 134 from the indoor side. The cover member 134 is attached by being engaged with the attachment groove 135 of the one frame 103, and the inner peripheral portion and the outer peripheral portion are arranged on the outdoor side toward the inner peripheral side and the outer peripheral side, respectively, in consideration of design. The whole frame 103 is covered and concealed. Further, between the screw hole 131 and the engaging portion 132 on the outdoor side surface of the one frame 103, the inner peripheral side portion and the outer peripheral side portion of the expected surface portion 146 on the indoor side surface of the other frame 104, and the outdoor side surface of the finding surface portion 147. Is attached with a refractory material 8 extending over each of the four sides, and the refractory material 8 on the indoor side and the outdoor side face each other. The refractory material 8 expands by foaming due to heat during a fire.

このように構成した戸の第二実施形態においても、第一実施形態と同様に、戸の室内側（一方側）で火災が発生した場合、一方枠体１０３が溶解・脱落しても、他方枠体１０４は溶解せず、ネジ止め部１４１にネジが掛かった状態が維持され、室内側（一方側）の耐火性パネル５ａの延出部５１にネジ止めした他方枠体１０４は脱落しない。また、戸の室外側（他方側）で火災が発生した場合、他方枠体１０４の室外側（他方側）の露出部分が溶解しても、他方枠体１０４のネジ止め部１４１は、開口部１１内に奥まっており、また耐火材８が熱により発泡してネジ止め部１４１を覆うため、少なくとも見付面部１４７は溶解せずに残存する。これにより、残存したネジ止め部１４１の見付面部１４７にネジが掛かった状態が維持され、ネジ止め部１４１の見付面部１４７とともに室内側（一方側）の耐火性パネル５ａの延出部５１を挟み込んでネジ止めした一方枠体１０３は脱落しない。よって、何れの場合においても、火災が発生した側の反対側の枠体は、脱落せず維持される。そして、一般に火災が発生した側は正圧となり、ガラスパネル２は残った枠体に押圧されて脱落しないので、開口部１１において室内側と室外側とが連通しない。このようにして、本発明の戸により火炎や煙が遮断され、延焼が防がれる。さらに、火災時には、耐火材８が熱により発泡して膨張し、ガラスパネル２の周縁部と他方枠体１０４のネジ止め部１４１の間の空間及び戸本体１の開口縁部と他方枠体１０４のネジ止め部１４１の間の空間に充満するので、気密が維持され、より確実に火炎や煙が遮断される。 Even in the second embodiment of the door configured as described above, as in the first embodiment, when a fire occurs on the indoor side (one side) of the door, even if one frame 103 is dissolved and dropped, the other The frame body 104 is not melted, the state where the screwing portion 141 is screwed is maintained, and the other frame body 104 screwed to the extending portion 51 of the fireproof panel 5a on the indoor side (one side) does not fall off. In addition, when a fire occurs on the outdoor side (the other side) of the door, even if the exposed part on the outdoor side (the other side) of the other frame 104 is melted, the screwing portion 141 of the other frame 104 is an opening 11 and the refractory material 8 is foamed by heat and covers the screwing portion 141, so that at least the finding surface portion 147 remains without being dissolved. Thereby, the state where the screw is applied to the finding surface portion 147 of the remaining screwing portion 141 is maintained, and the extension portion 51 of the fireproof panel 5a on the indoor side (one side) together with the finding surface portion 147 of the screwing portion 141. On the other hand, the frame 103 that is screwed in is not dropped. Therefore, in any case, the frame on the side opposite to the side where the fire has occurred is maintained without dropping. In general, the side where the fire has occurred becomes positive pressure, and the glass panel 2 is pressed by the remaining frame and does not fall off, so the indoor side and the outdoor side do not communicate with each other at the opening 11. In this way, flames and smoke are blocked by the door of the present invention, and fire spread is prevented. Further, in the event of a fire, the refractory material 8 is expanded by foaming due to heat, and the space between the peripheral edge of the glass panel 2 and the screwing portion 141 of the other frame 104 and the opening edge of the door body 1 and the other frame 104. Since the space between the screwing portions 141 is filled, airtightness is maintained, and flame and smoke are more reliably blocked.
