前記スチールドアは、各金属製面材と金属製四周枠との間に、熱膨張耐火部材を設けることで、断熱性能と防火性能とを両立させていたが、金属製四周枠が各金属製面材に近接配置されていたため、断熱性能を高めることが難しいという課題があった。 The steel door was made to have both thermal insulation performance and fire protection performance by providing a thermal expansion fireproof member between each metal face material and the metal four-sided frame, but the metal four-sided frame was made of each metal. Since it was placed close to the face material, there was a problem that it was difficult to improve the heat insulation performance.

本発明の目的は、断熱性能を向上でき、防火性能も確保できる戸体および建具を提供することにある。 An object of the present invention is to provide a door and a fitting that can improve heat insulation performance and can also secure fire protection performance.

本発明の戸体は、上骨、下骨および左右の縦骨を枠組みして構成された枠体と、前記枠体の屋外面に配置された金属製の屋外面材と、前記枠体の屋内面に配置された金属製の屋内面材と、前記屋外面材および前記屋内面材間に配置された断熱芯材と、を備えた戸体であって、前記上骨、下骨および左右の縦骨は、樹脂製の樹脂骨材と、前記樹脂骨材の内周側に配置された金属製の金属骨材とを備え、前記樹脂骨材は、前記屋外面材に沿って配置された屋外片部と、前記屋内面材に沿って配置された屋内片部と、前記屋外片部および前記屋内片部間を連結する連結片部とを備え、前記金属骨材は、前記屋内片部から屋外側に離れた位置に配置され、前記金属骨材および前記屋内片部間には、前記樹脂骨材の長手方向に沿って間隔を空けて複数個配置されて前記金属骨材に連結された金属製のブラケットと、少なくとも前記各ブラケット間に跨がって配置された断熱材とが設けられ、前記屋外面材は、前記樹脂骨材を介して前記金属骨材に固定され、前記屋内面材は、前記樹脂骨材を介して前記ブラケットに固定されていることを特徴とする。 The door body of the present invention is a frame body configured by framing the upper bone, the lower bone and the left and right vertical bones, a metal outdoor surface material arranged on the outdoor surface of the frame body, and the frame body of the frame body. A door body including a metal indoor surface material arranged on an indoor surface, and an insulating core material arranged between the outdoor surface material and the indoor surface material, wherein the upper bone, the lower bone, and the left and right bones Of the longitudinal bone comprises a resin aggregate made of resin and a metal aggregate made of metal arranged on the inner peripheral side of the resin aggregate, and the resin aggregate is arranged along the outdoor surface material. An outdoor piece, an indoor piece arranged along the indoor surface material, and a connecting piece connecting the outdoor piece and the indoor piece, the metal aggregate being the indoor piece. Located at a position away from the metal aggregate to the outdoor side, and a plurality of metal aggregates and the indoor piece are arranged at intervals along the longitudinal direction of the resin aggregate and connected to the metal aggregate. And a heat insulating material that is disposed across at least the respective brackets are provided, the outdoor surface material is fixed to the metal aggregate through the resin aggregate, and The indoor surface material is fixed to the bracket through the resin aggregate.

本発明によれば、戸体における枠体を構成する上骨、下骨、縦骨を、樹脂骨材および金属骨材で構成し、戸体の屋外面材および屋内面材は、樹脂骨材の屋外片部および屋内片部に沿って配置し、金属骨材は、屋内片部から屋外側に離れた位置に配置している。金属骨材は、屋内面材から離れて配置されるため、屋内面材および金属骨材間での熱流出を低減でき、金属製四周枠が表面材に近接配置された前記特許文献のスチールドアに比べて断熱性能を向上できる。
また、金属骨材と屋内片部との間には、金属製のブラケットが配置されているが、このブラケットは、金属骨材のように樹脂骨材の長手方向に沿って連続する長尺材ではなく、間隔を空けて配置されるピース部材であるため、ブラケットを介した熱流出も最小限に抑制できる。その上、金属骨材と屋内片部との間には、断熱材を設けたので、屋内面材および金属骨材間での熱流出をさらに低減できる。
金属骨材と金属製のブラケットとは連結されており、屋外面材は樹脂骨材を介して金属骨材に固定され、屋内面材は樹脂骨材を介してブラケットに固定されているため、火災時に樹脂骨材が焼失しても、屋外面材、金属骨材、ブラケット、屋内面材は互いに連結された状態を維持できる。したがって、樹脂骨材が焼失しても、戸体としての形状や構造を維持でき、戸体による遮炎性能も維持できるため、戸体に求められる防火性能を確保できる。 According to the present invention, the upper bone, the lower bone, and the vertical bone that form the frame body in the door body are made of resin aggregate and metal aggregate, and the outdoor surface material and indoor surface material of the door body are made of resin aggregate material. Are arranged along the outdoor piece and the indoor piece, and the metal aggregate is arranged at a position away from the indoor piece to the outdoor side. Since the metal aggregate is arranged away from the indoor surface material, it is possible to reduce heat outflow between the indoor surface material and the metal aggregate material, and the steel door of the patent document in which the metal four-sided frame is arranged close to the surface material. Insulation performance can be improved compared to.
In addition, a metal bracket is arranged between the metal aggregate and the indoor piece, but this bracket is a long member that is continuous along the longitudinal direction of the resin aggregate like the metal aggregate. Rather, it is a piece member arranged with a space, so that heat outflow through the bracket can be suppressed to a minimum. In addition, since the heat insulating material is provided between the metal aggregate and the indoor piece, the heat outflow between the indoor face material and the metal aggregate can be further reduced.
Since the metal aggregate and the metal bracket are connected, the outdoor face material is fixed to the metal aggregate via the resin aggregate, and the indoor face material is fixed to the bracket via the resin aggregate, Even if the resin aggregate burns down in the event of a fire, the outdoor surface material, the metal aggregate, the bracket, and the indoor surface material can remain connected to each other. Therefore, even if the resin aggregate burns down, the shape and structure of the door body can be maintained, and the flame shielding performance of the door body can be maintained, so that the fireproof performance required for the door body can be secured.

本発明の戸体において、前記樹脂骨材は、前記屋外片部および前記屋内片部間において前記連結片部から戸体の面内方向に突出して設けられた区画片部を備え、前記区画片部には、前記樹脂骨材の長手方向の複数箇所に切欠部が形成され、前記金属骨材は、前記樹脂骨材の前記屋外片部および前記区画片部間に配置され、前記ブラケットは、前記切欠部に配置されて前記金属骨材に連結されていることが好ましい。 In the door body of the present invention, the resin aggregate includes a partition piece portion projecting in the in-plane direction of the door body from the connecting piece portion between the outdoor piece portion and the indoor piece portion, and the partition piece. In the part, notches are formed at a plurality of positions in the longitudinal direction of the resin aggregate, the metal aggregate is arranged between the outdoor piece portion and the partition piece portion of the resin aggregate, and the bracket is It is preferable that the metal aggregate is arranged in the cutout portion and is connected to the metal aggregate.

本発明によれば、金属骨材の屋内側には、樹脂骨材の区画片部が設けられるため、金属骨材および屋内面材間の熱流出をさらに低減できる。また、区画片部に切欠部を形成し、この切欠部にブラケットを配置しているので、金属骨材およびブラケットを直接当接させることができ、リベット等で容易に連結できる。 According to the present invention, since the partition part of the resin aggregate is provided on the indoor side of the metal aggregate, the heat outflow between the metal aggregate and the indoor face material can be further reduced. Further, since the cutout portion is formed in the partition piece portion and the bracket is arranged in this cutout portion, the metal aggregate and the bracket can be directly brought into contact with each other and can be easily connected by a rivet or the like.

本発明の戸体は、前記屋外面材と前記金属骨材との間には、前記樹脂骨材と屋外側加熱発泡材とが配置され、前記屋内面材と前記ブラケットおよび前記断熱材との間には、前記樹脂骨材と屋内側加熱発泡材とが配置されていることが好ましい。 In the door body of the present invention, between the outdoor surface material and the metal aggregate, the resin aggregate and the outdoor-side heating foam material are arranged, and the indoor surface material, the bracket, and the heat insulating material. It is preferable that the resin aggregate and the indoor-side heat-foamed material are disposed between the two.

ここで、屋外側加熱発泡材や屋内側加熱発泡材は、樹脂骨材と一体に成形されたものでもよいし、樹脂骨材に接着剤などで貼られたものでもよい。
本発明によれば、屋外面材および金属骨材間に、樹脂骨材および屋外側加熱発泡材を配置したので、樹脂骨材が焼失した際に、屋外面材および金属骨材間を、膨張した屋外側加熱発泡材で塞ぐことができる。
また、屋内面材とブラケットとの間や、屋内面材と断熱材との間に、樹脂骨材および屋内側加熱発泡材を配置したので、樹脂骨材が焼失した際に、屋内面材と、ブラケットおよび断熱材間を、膨張した屋内側加熱発泡材で塞ぐことができる。
したがって、戸体の断熱芯材が加熱されてガスが発生した場合に、そのガスが各面材の内面に沿って戸体外部に流出することを防止できる。 Here, the outdoor side heated foam material and the indoor side heated foam material may be integrally molded with the resin aggregate or may be adhered to the resin aggregate with an adhesive or the like.
According to the present invention, since the resin aggregate and the outdoor-side heat-foamed material are arranged between the outdoor surface material and the metal aggregate, when the resin aggregate burns down, the space between the outdoor surface material and the metal aggregate expands. It can be closed with the outdoor foam material.
Further, since the resin aggregate and the indoor-side heat-foaming material are arranged between the indoor face material and the bracket, or between the indoor face material and the heat insulating material, when the resin aggregate burns down, The space between the bracket and the heat insulating material can be closed with the expanded indoor heating foam material.
Therefore, when the heat insulating core material of the door body is heated and gas is generated, the gas can be prevented from flowing out of the door body along the inner surface of each face material.

本発明の戸体において、少なくとも一方の前記縦骨における前記樹脂骨材の前記連結片部および前記金属骨材には、扉の付属部品を取り付けるための貫通孔が形成され、前記貫通孔が形成された前記連結片部には加熱発泡材が上下方向に連続して形成され、前記貫通孔は、前記連結片部の見込み方向における前記加熱発泡材の形成位置を含んで形成され、前記加熱発泡材は前記貫通孔で分断されていることが好ましい。 In the door body of the present invention, a through hole for attaching an accessory part of the door is formed in at least one of the connecting piece portion of the resin aggregate and the metal aggregate in the vertical bone, and the through hole is formed. A heat-foaming material is continuously formed in the vertical direction on the formed connecting piece, and the through-hole is formed to include a formation position of the heat-foaming material in the prospective direction of the connection piece. The material is preferably divided by the through holes .

本発明によれば、錠ケースや、扉内部の電気錠などに扉外部から給電するための通電金具等の扉の付属部品を取り付ける貫通孔に対応する位置に加熱発泡材を設けているので、火災時に樹脂骨材が焼失しても、金属骨材の貫通孔と錠ケースなどの付属部品間の隙間を、膨張した加熱発泡材で塞ぐことができる。
したがって、戸体の断熱芯材が加熱されてガスが発生した場合に、そのガスが付属部品を取り付ける貫通孔を通して戸体外部に流出することを防止できる。 According to the present invention, the heating foam is provided at the position corresponding to the through hole for attaching the accessory part of the door such as the current-carrying metal fitting for supplying power from the outside of the door to the lock case and the electric lock inside the door. Even if the resin aggregate is burnt out in the event of a fire, the gap between the through hole of the metal aggregate and the accessory such as the lock case can be closed with the expanded expanded foam material.
Therefore, when the heat insulating core material of the door body is heated and gas is generated, the gas can be prevented from flowing out of the door body through the through hole for attaching the accessory.

本発明の戸体において、前記樹脂骨材の前記連結片部において、前記ブラケットおよび前記断熱材に対向する位置には加熱発泡材が設けられていることが好ましい。 In the door body of the present invention, it is preferable that a heating foam material is provided at a position of the connecting piece portion of the resin aggregate facing the bracket and the heat insulating material.

本発明によれば、火災時に樹脂骨材が焼失しても、前記ブラケットと断熱材との隙間や、前記金属骨材と断熱材との隙間を、膨張した加熱発泡材で塞ぐことができる。
したがって、戸体の断熱芯材が加熱されてガスが発生した場合に、そのガスがブラケットや金属骨材と断熱材との隙間を通して戸体外部に流出することを防止できる。 According to the present invention, even if the resin aggregate is burned out in the event of a fire, the gap between the bracket and the heat insulating material and the gap between the metal aggregate and the heat insulating material can be closed with the expanded heated foam material.
Therefore, when the heat insulating core material of the door body is heated and gas is generated, the gas can be prevented from flowing out of the door body through the gap between the bracket or the metal aggregate and the heat insulating material.

本発明の戸体において、前記樹脂骨材は、合成樹脂材と加熱発泡材との一体成形品であることが好ましい。 In the door body of the present invention, it is preferable that the resin aggregate is an integrally molded product of a synthetic resin material and a heat-foamable material.

本発明によれば、合成樹脂材と加熱発泡材との一体成形品で樹脂骨材を構成しているので、樹脂骨材に加熱発泡材を後から貼り付ける場合に比べて経年劣化における剥がれがおきにくい。また、加熱発泡材の配置位置や形状の自由度が高いため、剛性が低い加熱発泡材の量（体積）を必要最小限に抑えることができ、樹脂骨材の強度を確保できる。 According to the present invention, since the resin aggregate is composed of an integrally molded product of the synthetic resin material and the heat-foamed material, peeling due to deterioration over time is more likely to occur than when the heat-foamed material is later attached to the resin aggregate. It's hard to get up. Further, since the arrangement position and shape of the heating foam material have a high degree of freedom, the amount (volume) of the heating foam material having low rigidity can be suppressed to a necessary minimum, and the strength of the resin aggregate can be secured.

本発明の建具は、上枠、下枠および左右の縦枠を備える建具枠と、前記建具枠に対して開閉可能に取り付けられた前記戸体と、を備えることを特徴とする。 The fitting of the present invention is characterized by including a fitting frame including an upper frame, a lower frame, and left and right vertical frames, and the door body attached to the fitting frame so as to be openable and closable.

In the vertical bones 80 and 90, the heat-foamable materials 565 and 566 provided on the indoor side of the lock case 6 in the prospective direction of the door 5 are second heat-foaming materials.

樹脂エッジ材５６は、扉５を閉めた際に、前記サブタイト材３６，４６が当接する位置に配置されている。すなわち、樹脂エッジ材５６は、サブタイト材３６，４６の当接位置の屋外側および屋内側に跨がって配置されている。このため、扉５を閉めた場合に、屋内部材３２，４２、メインタイト材３５，４５、サブタイト材３６，４６、樹脂エッジ材５６で囲まれた密閉空気層が形成される。この密閉空気層は、周囲が熱伝導率の低い合成樹脂材で囲まれるため、断熱性能が向上する。
また、本体部５６２が傾斜配置されているため、扉５を閉めた際に、樹脂エッジ材５６は、サブタイト材３６，４６に徐々に当接し、サブタイト材３６，４６のリップ部を徐々に湾曲させるため、扉５をスムーズに開閉でき、扉５を閉めた際のサブタイト材３６，４６と樹脂エッジ材５６の密着性も向上できる。 The resin edge material 56 is arranged at a position where the subtight materials 36 and 46 come into contact with each other when the door 5 is closed. That is, the resin edge material 56 is arranged so as to straddle the outdoor side and the indoor side of the contact position of the subtight materials 36 and 46. Therefore, when the door 5 is closed, a closed air layer surrounded by the indoor members 32 and 42, the maintight materials 35 and 45, the subtight materials 36 and 46, and the resin edge material 56 is formed. Since this closed air layer is surrounded by a synthetic resin material having a low thermal conductivity, the heat insulation performance is improved.
Further, since the main body portion 562 is arranged so as to be inclined, when the door 5 is closed, the resin edge material 56 gradually abuts on the subtight materials 36 and 46, and the lip portions of the subtight materials 36 and 46 are gradually curved. Therefore, the door 5 can be smoothly opened and closed, and the adhesion between the subtight materials 36 and 46 and the resin edge material 56 when the door 5 is closed can be improved.

Further, the metal edge material 55B is provided with through holes corresponding to the through holes 95 and 97 formed in the resin aggregate 810 and the metal aggregate 820 of the vertical bone 90, and the through holes 95 and 97 have lock cases. 6 are arranged.
On the other hand, the latch member 47 and the lock receiver are screwed to the outdoor member 41 of the vertical frame 40 according to the position of the lock case 6.

吊元側の縦骨８０および縦枠３０には、図３に示すように、ピボットヒンジ４がネジ止めされている。すなわち、ピボットヒンジ４のプレート４Ａは、縦枠３０の屋外部材３１に補強板材３７、３８を介してネジ止めされている。また、ピボットヒンジ４のプレート４Ｂは、金属エッジ材５５に当接配置され、プレート４Ｂから金属エッジ材５５、樹脂骨材８１０、金属骨材８２０を介して裏板８２５にネジ止めされており、十分な取付強度を確保できる。
さらに、扉５に電気錠が設けられている場合のように、扉５の内部と躯体１００側との間で通電が必要な場合、縦骨８０の金属エッジ材５５Ａ、樹脂骨材８１０、金属骨材８２０に貫通孔を形成し、通電金具などを配置している。 As shown in FIG. 3, the pivot hinge 4 is screwed to the vertical bone 80 and the vertical frame 30 on the hanging side. That is, the plate 4A of the pivot hinge 4 is screwed to the outdoor member 31 of the vertical frame 30 via the reinforcing plate members 37 and 38. Further, the plate 4B of the pivot hinge 4 is disposed in contact with the metal edge material 55, and is screwed from the plate 4B to the back plate 825 via the metal edge material 55, the resin aggregate 810, and the metal aggregate 820, Sufficient mounting strength can be secured.
Furthermore, when electricity needs to be supplied between the inside of the door 5 and the side of the body 100, as in the case where the door 5 is provided with an electric lock, the metal edge material 55A of the longitudinal bone 80, the resin aggregate 810, the metal A through hole is formed in the aggregate 820, and a current-carrying metal fitting and the like are arranged.

図９に示すように、上骨６０や下骨７０の樹脂骨材６１０の加熱発泡材６１８は、樹脂骨材６１０が焼失した際に、不燃断熱材５４やブラケット６３０と、上枠１０の下面部１１３や、下枠２０の屋外部材２１１との隙間を塞ぐ。
図１０に示すように、縦骨８０、９０の樹脂エッジ材５６に設けられた加熱発泡材５６５、５６６は、金属エッジ材５５や屋内面材５２と、側面部３１３、４１３や屋内部材３２、４２の加熱発泡材３４，４４との隙間を塞ぐ。
図７に示す加熱発泡材６１８と、図１０に示す加熱発泡材５６５，５６６とは、ドア１の見込み方向の位置が一致しているので、扉５の見込み面に四周連続する第二加熱発泡材ラインを形成し、ドア枠２と扉５間の隙間を塞ぐ。
また、図１０に示すように、サブタイト材３６、４６は、見込み方向の位置が、樹脂エッジ材５６の加熱発泡材５６５と加熱発泡材５６６との間に配置されているので、発泡した加熱発泡材５６５、５６６間に配置される。
さらに、水密材５７に設けられた加熱発泡材５７１は、膨張すると金属エッジ材５５と、屋外部材３１、４１との隙間部分を塞ぐ。 As shown in FIG. 9, the heat-foamable material 618 of the resin aggregate 610 of the upper bone 60 and the lower bone 70 has the non-combustible heat insulating material 54 and the bracket 630 and the lower surface of the upper frame 10 when the resin aggregate 610 burns down. The gap between the portion 113 and the outdoor member 211 of the lower frame 20 is closed.
As shown in FIG. 10, the heat-foamable materials 565 and 566 provided on the resin edge material 56 of the vertical bones 80 and 90 include the metal edge material 55 and the indoor surface material 52, and the side surface portions 313 and 413 and the indoor member 32, The gap between the heated foam material 34 and 44 of 42 is closed.
Since the positions of the heating foam material 618 shown in FIG. 7 and the heating foam materials 565 and 566 shown in FIG. 10 coincide with each other in the prospective direction of the door 1, the second heat foaming material which continues four rounds on the prospective surface of the door 5. A material line is formed to close the gap between the door frame 2 and the door 5.
Further, as shown in FIG. 10, since the sub-tight materials 36 and 46 are arranged at the position in the prospective direction between the heat foam material 565 and the heat foam material 566 of the resin edge material 56, the foamed heat foam material is formed. It is arranged between the materials 565 and 566.
Further, the heat-foamable material 571 provided on the watertight material 57 closes the gap between the metal edge material 55 and the outdoor members 31, 41 when expanded.

図４に示すように、ドア１の見込み方向において、加熱発泡材１４が配置された範囲の一部は、扉５の見込み面（上面）と重なり（ラップし）、扉５の見込み面に対向する。このため、図９に示すように、屋内部材１２の一部が焼失し、加熱発泡材１４が発泡すると、加熱発泡材１４は中空部１２１の内部空間を充填し、さらに扉５の屋内面材５２の上面やメインタイト材１５に当接し、上枠１０と扉５との間の隙間を塞ぐ。
同様に、図５に示すように、縦枠３０、４０の屋内部材３２、４２に設けられた加熱発泡材３４、４４も、ドア１の見込み方向において、少なくとも一部が扉５の見込み面（側面）と重なり（ラップし）、扉５の側面（見込み面）に対向する。このため、図１０に示すように、屋内部材３２，４２の一部が焼失し、加熱発泡材３４，４４が発泡すると、加熱発泡材３４，４４は中空部３２３、４２３間を充填し、さらに扉５の樹脂エッジ材５６に設けられた加熱発泡材５６６等に当接し、縦枠３０，４０と扉５との間の隙間を塞ぐ。 As shown in FIG. 4, in the prospective direction of the door 1, a part of the range in which the heated foam material 14 is arranged overlaps (wraps) the prospective surface (upper surface) of the door 5 and faces the prospective surface of the door 5. To do. For this reason, as shown in FIG. 9, when a part of the indoor member 12 is burned down and the heated foam material 14 is foamed, the heated foam material 14 fills the internal space of the hollow portion 121 and further the indoor surface material of the door 5. It contacts the upper surface of 52 and the maintight material 15, and closes the gap between the upper frame 10 and the door 5.
Similarly, as shown in FIG. 5, the heating foam members 34 and 44 provided on the indoor members 32 and 42 of the vertical frames 30 and 40 have at least a part of the prospective surface of the door 5 in the prospective direction of the door 1 ( It overlaps (wraps) the side surface and faces the side surface (expected surface) of the door 5.

以上のように、火災時には各加熱発泡材が発泡し、扉５内部を密閉したり、ドア枠２および扉５間の隙間を塞ぐため、ドア１において必要な防火性能が確保される。 As described above, when a fire occurs, each heating foam material foams to seal the inside of the door 5 or close the gap between the door frame 2 and the door 5, so that the fire prevention performance required in the door 1 is secured.

［実施形態による効果］
（１）扉５の枠体５０として樹脂骨材６１０、８１０を用い、樹脂骨材６１０、８１０に屋外面材５１および屋内面材５２を取り付けているので、金属骨材に各面材を取り付ける場合に比べて、断熱性能を向上できる。
樹脂骨材６１０、８１０の補強材である金属骨材６２０、８２０は、扉５の屋内面材５２の位置までは設けられておらず、金属骨材６２０、８２０と屋内面材５２とは扉５の見込み寸法の１／３程度の寸法分、離れているので、金属骨材６２０、８２０および屋内面材５２間での熱流出を低減でき、断熱性能を向上できる。
また、金属骨材６２０、８２０に連結されたブラケット６３０、８３０は、短尺のピース状に形成され、２〜５個程度しか設けられていないので、ブラケット６３０、８３０を介して屋内面材５２に熱が伝わることも抑制できる。特に、ブラケット６３０、８３０は、アングル材で構成され、屋内面材５２に最も近い部分は、受け片部６３１，８３１の端縁であって面積も小さいため、ブラケット６３０、８３０および屋内面材５２間の熱流出を低減できる。
金属骨材６２０、８２０と、屋内面材５２との間の空間には、不燃断熱材５４が配置されているので、さらに断熱性能を向上できる。したがって、高断熱の扉５とすることができる。 [Effects of the embodiment]
(1) Since the resin aggregates 610 and 810 are used as the frame body 50 of the door 5 and the outdoor face material 51 and the indoor face material 52 are attached to the resin aggregates 610 and 810, each face material is attached to the metal aggregate. Insulation performance can be improved compared with the case.
The metal aggregates 620 and 820, which are reinforcing materials for the resin aggregates 610 and 810, are not provided up to the position of the indoor surface material 52 of the door 5, and the metal aggregates 620 and 820 and the indoor surface material 52 are doors. Since the distance is about 1/3 of the expected size of 5, the heat outflow between the metal aggregates 620 and 820 and the indoor face material 52 can be reduced, and the heat insulation performance can be improved.
Further, since the brackets 630 and 830 connected to the metal aggregates 620 and 820 are formed in a short piece shape and only about 2 to 5 pieces are provided, the brackets 630 and 830 are provided on the indoor surface material 52 via the brackets 630 and 830. It is possible to suppress heat transfer. In particular, the brackets 630 and 830 are made of angle material, and the portion closest to the indoor surface material 52 is the edge of the receiving piece portions 631 and 831 and has a small area. Therefore, the brackets 630 and 830 and the indoor surface material 52 are The heat outflow during the period can be reduced.
Since the noncombustible heat insulating material 54 is disposed in the space between the metal aggregates 620 and 820 and the indoor surface material 52, the heat insulating performance can be further improved. Therefore, the door 5 with high heat insulation can be obtained.

（２）金属骨材６２０、８２０およびブラケット６３０、８３０を連結具６３３、８３３で連結し、さらに、屋外面材５１および屋内面材５２を、樹脂骨材６１０、８１０を介して、金属骨材６２０、８２０およびブラケット６３０、８３０にリベット６５で固定しているので、火災時に樹脂骨材６１０、８１０が焼失したとしても、屋外面材５１、金属骨材６２０、８２０、ブラケット６３０、８３０、屋内面材５２が連結された状態を維持できる。したがって、火災時に扉５の形態を維持でき、遮炎性能も確保できる。 (2) The metal aggregates 620 and 820 and the brackets 630 and 830 are connected by the connecting tools 633 and 833, and the outdoor surface material 51 and the indoor surface material 52 are further connected via the resin aggregates 610 and 810. Since the rivets 65 are fixed to the 620, 820 and the brackets 630, 830, even if the resin aggregates 610, 810 are burnt out in the event of a fire, the outdoor face material 51, the metal aggregates 620, 820, the brackets 630, 830, the indoors The face material 52 can be maintained in a connected state. Therefore, the form of the door 5 can be maintained at the time of a fire, and the flame shielding performance can also be secured.

（３）不燃断熱材５４は、少なくとも複数のブラケット６３０間や、ブラケット８３０間に跨がって配置されているので、ブラケット６３０、８３０間の空間を不燃断熱材５４で塞ぐことができる。
このため、不燃断熱材５４の周囲に設けられた加熱発泡材６１６、８１６、６１８、８１９が発泡時に塞ぐ必要がある空間の体積が、不燃断熱材５４を設けない場合に比べて小さくなり、加熱発泡材６１６、８１６、６１８、８１９の量を大幅に少なくでき、コストも低減でき、樹脂骨材６１０、８１０の剛性も確保できる。
また、加熱発泡材６１８は、不燃断熱材５４があるため、上枠１０側や下枠２０側に確実に発泡させることができ、上枠１０と上骨６０間の隙間や、下枠２０と下骨７０間の隙間を確実に塞ぐことができる。 (3) Since the noncombustible heat insulating material 54 is arranged at least between the plurality of brackets 630 and across the brackets 830, the space between the brackets 630 and 830 can be closed with the noncombustible heat insulating material 54.
For this reason, the volume of the space that the heating foam materials 616, 816, 618, and 819 provided around the noncombustible heat insulating material 54 need to be closed at the time of foaming becomes smaller than that in the case where the noncombustible heat insulating material 54 is not provided. The amount of the foam materials 616, 816, 618, 819 can be significantly reduced, the cost can be reduced, and the rigidity of the resin aggregates 610, 810 can be secured.
Further, since the heat-foamable material 618 has the non-combustible heat insulating material 54, it can be surely foamed to the upper frame 10 side or the lower frame 20 side, and the gap between the upper frame 10 and the upper frame 60 or the lower frame 20 side. It is possible to reliably close the gap between the lower bones 70.

（４）加熱発泡材６１５、６１６、６１８、８１５、８１６、８１７、８１８、８１９によって、扉５内部を密封することができるため、樹脂骨材６１０、８１０が焼失しても、断熱芯材５３が設けられた扉５の内部空間と扉５の外部との連通箇所を塞ぐことができる。したがって、加熱された断熱芯材５３からガスが発生しても、そのガスが扉５の外部に流出することを防止できる。 (4) Since the inside of the door 5 can be sealed by the heat-foaming materials 615, 616, 618, 815, 816, 817, 818, and 819, even if the resin aggregates 610 and 810 burn out, the heat-insulating core material 53 It is possible to close the communication place between the inner space of the door 5 provided with and the outside of the door 5. Therefore, even if gas is generated from the heated insulating core material 53, the gas can be prevented from flowing out of the door 5.

（５）樹脂骨材６１０、８１０に設けられる加熱発泡材６１５〜６１８、８１５〜８１９を、樹脂骨材６１０、８１０の製造時に同時押出成型で製造しているので、樹脂骨材６１０、８１０に、別途製造された加熱発泡材を後から貼り付ける場合に比べて、製造時の組立性や生産性も向上できる。また、加熱発泡材を後から貼り付けた場合、経年劣化により加熱発泡材が剥がれてくる可能性があり、定期的にメンテナンスが必要となるが、同時押出成型で製造した場合には経年劣化による加熱発泡材の剥がれがおきにくく、品質低下も防止できる。
また、加熱発泡材を後から貼り付ける場合は、構造上、樹脂骨材に対して取り付ける位置の制約を受けるため、防火性能を担保するための設計が困難となるが、本実施形態のように、同時押出成型によれば、加熱発泡材の配置位置や形状の自由度が高いため、防火性能も容易に担保できる。その上、剛性が低い加熱発泡材の量（体積）を必要最小限に抑えることができ、樹脂骨材６１０、８１０に必要な強度を容易に確保できる。 (5) Since the heat-foamable materials 615 to 618 and 815 to 819 provided on the resin aggregates 610 and 810 are manufactured by coextrusion molding when the resin aggregates 610 and 810 are manufactured, the resin aggregates 610 and 810 are manufactured. As compared with the case where a separately produced heat-foamable material is attached later, the assembling property and the productivity at the time of manufacturing can be improved. In addition, if the heated foam material is attached afterwards, the heated foam material may come off due to aging deterioration, and regular maintenance is required, but if it is manufactured by coextrusion molding, it may deteriorate due to aging. Peeling of the heated foam material does not occur easily, and deterioration of quality can be prevented.
Further, when the heat-foamable material is attached later, it is difficult to design for ensuring the fireproof performance because the structure restricts the position of attachment to the resin aggregate, but as in the present embodiment. According to the coextrusion molding, since the degree of freedom in the arrangement position and shape of the heated foam material is high, the fireproof performance can be easily ensured. Moreover, the amount (volume) of the heat-foamable material having low rigidity can be suppressed to a necessary minimum, and the strength required for the resin aggregates 610 and 810 can be easily ensured.

（６）加熱発泡材６１７と加熱発泡材５８とで扉５の見込み面において四周連続する第一加熱発泡材ラインを形成し、加熱発泡材６１８と、加熱発泡材５６５，５６６とで、扉５の見込み面において四周連続する第二加熱発泡材ラインを形成しているので、ドア枠２と扉５との間には、見込み方向に二重の遮炎ラインを構成でき、遮炎性能を向上できる。
さらに、二重の加熱発泡材ラインは、錠ケース６等の付属部品を挟んで屋外側および屋内側に形成されるため、加熱された断熱芯材５３から発生したガスが付属部品自体から流出しても、前記二重の加熱発泡材ライン間に密封することができる。
また、金属エッジ材５５、樹脂エッジ材５６は、扉５の構造体ではないため、構造や形状の自由度が高く、加熱発泡材の配置位置の制約も少ない。このため、金属エッジ材５５、樹脂エッジ材５６における加熱発泡材５８、５６５，５６６の配置位置は、上骨６０や下骨７０に設けられた加熱発泡材６１７，６１８の見込み方向の位置に容易に合わせることができ、扉５の見込み面に四周連続する第一加熱発泡材ライン、第二加熱発泡材ラインを容易に構成できる。 (6) The heat-foaming material 617 and the heat-foaming material 58 form a first heat-foaming material line that continues for four rounds on the prospective surface of the door 5, and the heat-foaming material 618 and the heat-foaming materials 565 and 566 form the door 5 Since the second heated foam material line that is continuous for four rounds is formed on the prospective plane of the above, a double flame shielding line can be formed between the door frame 2 and the door 5 in the prospective direction, and flame shielding performance is improved. it can.
Further, since the double heating foam material line is formed on the outdoor side and the indoor side with the accessory parts such as the lock case 6 sandwiched therebetween, the gas generated from the heated insulating core material 53 flows out from the accessory parts themselves. Also, it is possible to seal between the double heated foam lines.
Further, since the metal edge material 55 and the resin edge material 56 are not the structure of the door 5, there is a high degree of freedom in structure and shape, and there are few restrictions on the arrangement position of the heating foam material. Therefore, the positions of the heat-foaming materials 58, 565, 566 on the metal edge material 55 and the resin edge material 56 are easily located at the positions in the prospective direction of the heat-foaming materials 617, 618 provided on the upper bone 60 and the lower bone 70. Therefore, the first heated foam material line and the second heated foam material line which are continuous four times on the prospective surface of the door 5 can be easily configured.

（７）樹脂骨材６１０、８１０に設けられる加熱発泡材６１５〜６１８、８１５〜８１９のうち、樹脂骨材６１０、８１０の表面側に露出する加熱発泡材６１５，６１６，８１５，８１６は、屋外面材５１、屋内面材５２で覆われており、他の加熱発泡材６１７，６１８，８１７〜８１９は、樹脂骨材６１０、８１０の内面側（裏面側）に露出し、表面側には露出しない。このため、加熱発泡材６１５〜６１８、８１５〜８１９は、扉５の表面側に露出しないので、意匠性を向上できる。 (7) Among the heat-foamable materials 615 to 618 and 815 to 819 provided on the resin aggregates 610 and 810, the heat-foamable materials 615, 616, 815 and 816 exposed on the surface side of the resin aggregates 610 and 810 are outdoors. The surface material 51 and the indoor surface material 52 are covered, and the other heating foam materials 617, 618, 817 to 819 are exposed on the inner surface side (rear surface side) of the resin aggregates 610, 810 and exposed on the front surface side. do not do. Therefore, the heat-foamable materials 615 to 618 and 815 to 819 are not exposed on the front surface side of the door 5, so that the designability can be improved.

（８）樹脂エッジ材５６に設けられる加熱発泡材５６５、５６６も樹脂エッジ材５６の裏面側に設けられ、表面側には露出しないため、意匠性を向上できる。
また、金属エッジ材５５に設けられる加熱発泡材５８は、金属エッジ材５５の溝５５２内部、つまりポケット部に配置され、一部分のみが扉５の側面に露出するため、加熱発泡材５８も目立ちにくくでき、意匠性を向上できる。
さらに、これらの加熱発泡材５６５，５６６，５８は、扉５の金属エッジ材５５や樹脂エッジ材５６の表面に露出しないので、扉５の開閉時に、サブタイト材３６やサブタイト材４６に接触することがない。このため、加熱発泡材５６５，５６６，５８が摩耗することがなく、品質を維持できる。
また、扉５の縦骨８０，９０に金属エッジ材５５、樹脂エッジ材５６を取り付けているので、縦骨８０，９０の樹脂骨材８１０をエッジ材５５，５６で被覆でき、扉５の意匠性を向上できる。 (8) Since the heat-foamable materials 565 and 566 provided on the resin edge material 56 are also provided on the back surface side of the resin edge material 56 and are not exposed on the front surface side, the designability can be improved.
Further, the heat-foamable material 58 provided on the metal edge material 55 is arranged inside the groove 552 of the metal edge material 55, that is, in the pocket portion, and only a part of the heat-foamable material 58 is exposed on the side surface of the door 5, so that the heat-foamable material 58 is also inconspicuous. It is possible to improve the design.
Further, since these heat-foamable materials 565, 566, 58 are not exposed on the surface of the metal edge material 55 or the resin edge material 56 of the door 5, contact the subtight material 36 or the subtight material 46 when the door 5 is opened or closed. There is no. Therefore, the heated foam materials 565, 566, 58 are not worn and the quality can be maintained.
Further, since the metal edge material 55 and the resin edge material 56 are attached to the vertical bones 80 and 90 of the door 5, the resin aggregate 810 of the vertical bones 80 and 90 can be covered with the edge materials 55 and 56, and the door 5 design It is possible to improve the property.

（９）ドア１の見込み方向において、樹脂エッジ材５６の配置位置を、サブタイト材３６、４６の屋外側および屋内側に跨がるように配置し、加熱発泡材５６５がサブタイト材３６、４６の屋外側に膨張し、加熱発泡材５６６がサブタイト材３６、４６の屋内側に膨張するように構成したので、サブタイト材３６、４６は各加熱発泡材５６５、５６６に挟まれるため、扉５の見込み面への当接状態を維持できる。特に、加熱発泡材５６５および加熱発泡材５６６、３４、４４でサブタイト材３６、４６を覆って保護することができるため、耐燃性でないサブタイト材３６、４６の焼失を低減する、もしくは、焼失する時間を遅延させることができ、サブタイト材３６、４６および各加熱発泡材５６５、５６６、３４、４４でドア枠２および扉５間を塞いで遮縁性能を担保することができる。このため、サブタイト材３６，４６と加熱発泡材とでドア枠２および扉５間を塞ぐことができ、加熱発泡材のみで塞ぐ場合に比べて、遮炎性能を向上できる。
また、サブタイト材３６、４６のみでドア枠２および扉５間を塞いだ場合には、サブタイト材３６、４６の屋内外で圧力差が生じた際に、サブタイト材３６、４６がめくれて扉５から離れる可能性があるが、特にサブタイト材３６、４６の屋内側に加熱発泡材５６６、３４、４４を充填しているので、サブタイト材３６、４６の屋内外で圧力差が生じても扉５への当接状態を維持でき、遮炎性能を維持できる。
さらに、扉５の側面に、サブタイト材３６、４６および各加熱発泡材５６５、５６６を当接させているので、扉５が熱反りしても、扉５の側面への当接状態を維持でき、遮炎性能も維持できる。 (9) In the prospective direction of the door 1, the resin edge material 56 is arranged so as to straddle the outdoor side and the indoor side of the subtight materials 36 and 46, and the heated foam material 565 is disposed on the subtight materials 36 and 46. Since it expands to the outdoor side and the heated foam material 566 expands to the indoor side of the subtight materials 36 and 46, the subtight materials 36 and 46 are sandwiched between the respective heated foam materials 565 and 566, so that the door 5 is expected. The state of contact with the surface can be maintained. In particular, since it is possible to cover and protect the subtight materials 36 and 46 with the heat-foamable material 565 and the heat-foamable materials 566, 34, and 44, it is possible to reduce the burnout of the non-combustible subtight materials 36 and 46, or the time to burn out. Can be delayed, and the subtight materials 36 and 46 and the respective heat-foamable materials 565, 566, 34, and 44 can close the space between the door frame 2 and the door 5 to ensure the edge shielding performance. Therefore, the space between the door frame 2 and the door 5 can be closed by the sub-tight materials 36, 46 and the heat-foaming material, and the flame shielding performance can be improved as compared with the case where only the heat-foaming material is closed.
When the door frame 2 and the door 5 are closed only by the subtight materials 36 and 46, when the pressure difference between the subtight materials 36 and 46 is generated indoors and outdoors, the subtight materials 36 and 46 are turned up and the door 5 is closed. However, since the foaming materials 566, 34, and 44 are filled on the indoor side of the subtight materials 36 and 46 in particular, even if a pressure difference occurs inside and outside the subtight materials 36 and 46, the door 5 It is possible to maintain the contact state with and to maintain the flame shielding performance.
Further, since the sub-tight materials 36, 46 and the respective heat-foamable materials 565, 566 are in contact with the side surface of the door 5, even if the door 5 is warped, the contact state with the side surface of the door 5 can be maintained. Also, the flame shielding performance can be maintained.

（１０）水密材５７には加熱発泡材５７１が設けられているので、火災時には金属エッジ材５５と、屋外部材３１、４１との隙間部分を、加熱発泡材５７１で塞ぐことができる。 (10) Since the watertight material 57 is provided with the heated foam material 571, the gap portion between the metal edge material 55 and the outdoor members 31, 41 can be closed with the heated foam material 571 in the event of a fire.

（１１）屋内部材１２、３２、４２に設けられた加熱発泡材１４、３４、４４は、少なくとも一部が、扉５の見込み面と重なり（ラップし）、扉５の見込み面に対向する。このため、屋内部材１２、３２、４２の一部が焼失した場合、加熱発泡材１４、３４、４４は扉５の見込み面側に発泡して扉５の見込み面との隙間を塞ぐことができる。
また、これらの加熱発泡材１４、３４、４４は、中空部１２１、３２１、４２１内に設けられ、屋内部材１２、３２、４２の表面に露出しないため、ドア枠２の意匠性を向上できる。 (11) At least a part of the heated foam materials 14, 34, 44 provided on the indoor members 12, 32, 42 overlaps (wraps) the prospective surface of the door 5 and faces the prospective surface of the door 5. For this reason, when a part of the indoor members 12, 32, 42 is burnt out, the heated foam materials 14, 34, 44 foam on the prospective surface side of the door 5 and can close the gap with the prospective surface of the door 5. ..
Moreover, since these heat-foamable materials 14, 34, 44 are provided in the hollow portions 121, 321, 421 and are not exposed on the surfaces of the indoor members 12, 32, 42, the design of the door frame 2 can be improved.

（１２）屋内部材３２、４２に設けられた加熱発泡材３４、４４は、少なくとも一部が、ドア枠２の見込み方向において、サブタイト材３６、４６の取付位置と、メインタイト材３５、４５が取り付けられた保持片部３２２、４２２との間に配置されているので、各メインタイト材３５、４５およびサブタイト材３６、４６で囲まれる空間を加熱発泡材３４、４４で充填することができ、遮炎性能を向上できる。
また、加熱発泡材３４、４４が発泡した際には、サブタイト材３６、４６や、メインタイト材３５、４５を扉５に押し付ける方向に膨張できるので、火災時に縦枠３０、４０等や扉５が熱反りした場合でも、ドア枠２および扉５間を確実に塞ぐことができ、遮炎性能を向上できる。特に、扉５の見付け面に当接するタイト材は、扉５が熱反りした際に扉５に密着できない箇所が発生しやすいが、扉５の見込み面に当接するサブタイト材３６、４６を設けているので、扉５等が熱反りしても、扉５との密着状態を維持でき、遮炎性能も維持できる。 (12) At least a part of the heat-foamable materials 34, 44 provided on the indoor members 32, 42 is such that the installation positions of the subtight materials 36, 46 and the maintight materials 35, 45 are in the prospective direction of the door frame 2. Since it is arranged between the attached holding pieces 322, 422, the space surrounded by the main tight materials 35, 45 and the sub tight materials 36, 46 can be filled with the heated foam materials 34, 44. The flame shield performance can be improved.
Further, when the heat-foamable materials 34, 44 are foamed, they can be expanded in the direction in which the sub-tight materials 36, 46 and the main-tight materials 35, 45 are pressed against the door 5, so that the vertical frames 30, 40, etc. Even when the heat warps, the space between the door frame 2 and the door 5 can be reliably closed, and the flame shielding performance can be improved. In particular, the tight material that comes into contact with the found surface of the door 5 is likely to have a portion that cannot be brought into close contact with the door 5 when the door 5 is warped, but by providing the sub-tight materials 36 and 46 that come into contact with the prospective surface of the door 5, Therefore, even if the door 5 or the like warps, the close contact with the door 5 can be maintained and the flame shielding performance can be maintained.

［変形例］
なお、本発明は以上の実施形態で説明した構成のものに限定されず、本発明の目的を達成できる範囲での変形例は、本発明に含まれる。
例えば、ドア枠としては、図１１，１２に示すように、上枠１０Ａおよび縦枠３０Ａ，４０Ａをアルミ断熱形材で構成したドア枠２Ａを用いてもよい。なお、扉５や下枠２０は前記実施形態と同一の構成であるため、説明を省略する。
上枠１０Ａは、それぞれアルミ製の屋外部材１１Ａおよび屋内部材１２Ａを、ウレタン樹脂等の断熱部材１３Ａで連結して構成されている。縦枠３０Ａ、４０Ａは、アルミ製の屋外部材３１Ａ，４１Ａおよび屋内部材３２Ａ、４２Ａを、ウレタン樹脂等の断熱部材３３Ａ，４３Ａで連結して構成されている。
これらの上枠１０Ａ、縦枠３０Ａ，４０Ａでは、屋外部材１１Ａ，３１Ａ，４１Ａおよび屋内部材１２Ａ，３２Ａ，４２Ａが連結用ブラケット１７Ａを介して連結されている。これにより、断熱部材１３Ａ、３３Ａ，４３Ａが焼失した場合でも、屋外部材１１Ａ，３１Ａ，４１Ａおよび屋内部材１２Ａ，３２Ａ，４２Ａを連結した状態のまま維持できる。また、上枠１０Ａ、縦枠３０Ａ、４０Ａの断熱部材１３Ａ、３３Ａ，４３Ａの表面、つまり扉５側の面には、加熱発泡材１４Ａ、３４Ａ、４４Ａが貼られている。これにより、火災時には、加熱発泡材１４Ａ、３４Ａ、４４Ａが膨張して、断熱部材１３Ａ、３３Ａ，４３Ａを被覆するため、断熱部材１３Ａ、３３Ａ，４３Ａの焼失を防止できる。また、ドアは、上下の高さ寸法が大きいため、火災時には、縦枠３０Ａ，４０Ａ等が湾曲して扉５との隙間が生じやすいが、縦枠３０Ａ、４０Ａに加熱発泡材３４Ａ、４４Ａが貼られていれば、加熱発泡材３４Ａ、４４Ａの膨張によって扉５との隙間を塞いで遮炎性能を確保できる。
さらに、加熱発泡材３４Ａ、４４Ａは、メインタイト材３５、４５の取付位置と、サブタイト材３６、４６を保持する屋内部材３２Ａ，４２Ａの保持片部との間に配置されているので、各タイト材３５，４５，３６，４６で隠れて視認し難くでき、意匠性を向上できる。また、サブタイト材３６、４６の屋外側を加熱発泡材５６５で塞ぎ、屋内側を加熱発泡材５６６、３４Ａ、４４Ａで塞ぐことができるので、遮炎性能を向上できる。 [Modification]
It should be noted that the present invention is not limited to the configurations described in the above embodiments, and modifications within a range in which the object of the present invention can be achieved are included in the present invention.
For example, as the door frame, as shown in FIGS. 11 and 12, a door frame 2A in which the upper frame 10A and the vertical frames 30A and 40A are made of aluminum heat-insulating frame members may be used. Note that the door 5 and the lower frame 20 have the same configurations as those in the above-described embodiment, and therefore description thereof will be omitted.
The upper frame 10A is configured by connecting an aluminum outdoor member 11A and an indoor member 12A with a heat insulating member 13A such as urethane resin. The vertical frames 30A and 40A are configured by connecting aluminum outdoor members 31A and 41A and indoor members 32A and 42A with heat insulating members 33A and 43A such as urethane resin.
In the upper frame 10A and the vertical frames 30A, 40A, the outdoor members 11A, 31A, 41A and the indoor members 12A, 32A, 42A are connected via a connecting bracket 17A. As a result, even when the heat insulating members 13A, 33A, 43A are burnt out, the outdoor members 11A, 31A, 41A and the indoor members 12A, 32A, 42A can be maintained in a connected state. Further, on the surfaces of the heat insulating members 13A, 33A, 43A of the upper frame 10A and the vertical frames 30A, 40A, that is, the surface on the door 5 side, the heat foaming materials 14A, 34A, 44A are attached. As a result, at the time of fire, the heated foam materials 14A, 34A, 44A expand and cover the heat insulating members 13A, 33A, 43A, so that the heat insulating members 13A, 33A, 43A can be prevented from burning. In addition, since the door has a large vertical height, the vertical frames 30A, 40A and the like are bent during a fire to easily form a gap with the door 5, but the vertical frames 30A, 40A have the heated foam materials 34A, 44A. If it is attached, expansion of the heated foam materials 34A and 44A can close the gap with the door 5 and ensure flame shielding performance.
Furthermore, since the heat-foamable materials 34A and 44A are arranged between the mounting positions of the main tight materials 35 and 45 and the holding pieces of the indoor members 32A and 42A that hold the sub-tight materials 36 and 46, the tight foam materials 34A and 44A are not tight. The materials 35, 45, 36, and 46 can be hidden to make it difficult to visually recognize, and the designability can be improved. Further, since the outdoor side of the sub-tight materials 36 and 46 can be closed with the heated foam material 565 and the indoor side can be closed with the heated foam materials 566, 34A and 44A, the flame shielding performance can be improved.

本発明において、加熱発泡材は前記実施形態の例に限定されない。例えば、ドア枠側に、扉５の見込み面に折り返された屋外面材５１、屋内面材５２と、ドア枠との間を遮蔽する加熱発泡材を設け、これらの加熱発泡材でガスが外部に流出することを防止してもよい。この場合、扉５側には、加熱発泡材を設ける必要が無い。
さらに、扉５側に設けた各加熱発泡材の一部の機能を、ドア枠側に設けた加熱発泡材で実現させた場合には、対応する扉５側の加熱発泡材を無くすことができる。したがって、加熱発泡材の配置位置等は、実施にあたって適宜設計すれば良い。
また、加熱発泡材は、樹脂部品の同時押出成型で製造されるものに限定されず、同時押出成型以外の製法で樹脂部品に一体化されたものでもよいし、別途製造した加熱発泡材を樹脂部品に接着してもよい。さらに、樹脂骨材６１０、８１０における加熱発泡材の形成位置も前記実施形態に限定されない。例えば、加熱発泡材６１５、６１６、８１５、８１６は、樹脂骨材６１０、８１０の表面側に露出する位置に形成されていたが、裏面側に露出する位置に形成してもよく、これらは樹脂骨材６１０、８１０として必要な強度、加熱発泡材の量、意匠性などを考慮して設計すればよい。 In the present invention, the heat-foamable material is not limited to the example of the above embodiment. For example, on the door frame side, a heating foam material for shielding between the door surface and the outdoor surface material 51 and the indoor surface material 52 folded back to the prospective surface of the door 5 is provided, and gas is externally generated by these heating foam materials. It may be prevented from flowing out to. In this case, it is not necessary to provide a heating foam on the door 5 side.
Furthermore, when a part of the functions of each heating foam provided on the door 5 side is realized by the heating foam provided on the door frame side, the corresponding heating foam on the door 5 side can be eliminated. .. Therefore, the arrangement position and the like of the heat-foamable material may be appropriately designed in practice.
Further, the heat-foamable material is not limited to that manufactured by coextrusion molding of resin parts, and may be integrated with the resin parts by a method other than coextrusion molding. It may be adhered to the component. Further, the formation position of the heat-foamable material on the resin aggregates 610 and 810 is not limited to the above embodiment. For example, although the heat-foamable materials 615, 616, 815, 816 were formed at the positions exposed on the front surface side of the resin aggregates 610, 810, they may be formed at the positions exposed on the rear surface side. It may be designed in consideration of the strength required for the aggregates 610 and 810, the amount of the heat-foamable material, the designability, and the like.

樹脂骨材６１０、８１０の形状は、前記実施形態に限定されない。例えば、区画片部６１４、８１４を備えずに、断面略コ字状の樹脂骨材を用いてもよい。区画片部６１４、８１４が無くても、不燃断熱材５４を配置することで断熱性能を確保できるためである。
同様に、金属骨材６２０、８２０やブラケット６３０、８３０の形状も前記実施形態に限定されない。 The shapes of the resin aggregates 610 and 810 are not limited to those in the above embodiment. For example, the resin aggregate having a substantially U-shaped cross section may be used without the partition pieces 614 and 814. This is because even if the partition pieces 614 and 814 are not provided, the heat insulating performance can be secured by disposing the noncombustible heat insulating material 54.
Similarly, the shapes of the metal aggregates 620 and 820 and the brackets 630 and 830 are not limited to those in the above embodiment.

前記実施形態では、サブタイト材３６、４６はＴＰＯ製とし、メインタイト材３５、４５はＥＰＤＭ製やＰＶＣ製としていたが、これらの材質に限定されない。例えば、サブタイト材３６、４６や、メインタイト材３５、４５を、耐燃性の材質で構成してもよい。耐燃性の材質とは、燃焼に耐え得る性質を有する材質、具体的には、不燃性、難燃性、自己消火性、遅燃性等の燃えにくい材質を意味する。このような耐燃性の合成樹脂材でサブタイト材３６、４６を形成すれば、加熱発泡材５６５、５６６、３４、４４等と協働して遮炎性能をより向上できる。 In the above embodiment, the subtight materials 36 and 46 are made of TPO and the maintight materials 35 and 45 are made of EPDM or PVC, but the materials are not limited to these. For example, the subtight materials 36 and 46 and the maintight materials 35 and 45 may be made of flame-resistant materials. The flame-retardant material means a material having a property capable of withstanding combustion, specifically, a non-combustible material such as non-combustible, flame-retardant, self-extinguishing, and retarded. By forming the subtight materials 36 and 46 with such a flame-resistant synthetic resin material, the flame-shielding performance can be further improved in cooperation with the heat-foamable materials 565, 566, 34, 44 and the like.

本発明の建具は、採光部を備えないドア１であったが、採光部を有する扉５を用いてもよい。また、本発明の建具は、玄関ドアに限らず、勝手口ドアなど出入り口の各種ドアとして利用できる。この際、本発明は、親扉、子扉の２枚の扉が設けられた建具にも適用でき、さらには、引戸タイプの建具にも適用できる。 The fitting of the present invention is the door 1 that does not include a daylighting section, but a door 5 that has a daylighting section may be used. Further, the fitting of the present invention is not limited to the entrance door, and can be used as various doors such as a door without permission.
