Description

本発明は、建物の玄関、勝手口などに用いられる断熱ドアに関する。 TECHNICAL FIELD The present invention relates to an insulated door used for an entrance of a building, a self-contained door, and the like.

従来より、断熱ドアにおける断熱性能は、面積が大きな扉の断熱性能の影響が大きかった。このため、扉内部に断熱性を有する芯材を配置し、扉の熱流量を低減させて断熱ドアの断熱性能を向上させていた（例えば、特許文献１参照）。 Conventionally, the heat insulation performance of the heat insulation door is largely affected by the heat insulation performance of the door having a large area. For this reason, the core material which has heat insulation was arrange | positioned inside a door, the heat flow rate of the door was reduced, and the heat insulation performance of the heat insulation door was improved (for example, refer patent document 1).

特許第３３８６７５５号公報Patent No. 3386755

しかしながら、前記特許文献１のドアにおいては、アルミ押出形材からなる上枠、下枠、左右の縦枠を枠組みしてドア枠を構成していた。このため、ドア枠部分を介して熱が流出し、断熱性能を低下させていた。特に、ドアにおいては、縦枠の長さ寸法が大きいため、縦枠を介した熱流出が大きかった。
このため、ドアの縦枠における熱流量を低減させて、断熱ドアの断熱性能をさらに向上させることが求められている。 However, in the door of Patent Document 1, the door frame is configured by framing an upper frame, a lower frame, and left and right vertical frames made of an aluminum extruded material. For this reason, heat flowed out through the door frame portion to lower the heat insulation performance. In particular, in the door, since the length dimension of the vertical frame is large, the heat outflow through the vertical frame is large.
Therefore, it is required to further improve the heat insulation performance of the heat insulation door by reducing the heat flow rate in the vertical frame of the door.

本発明の目的は、ドアの縦枠の熱流量を低減できて断熱性能を向上できる断熱ドアを提供することにある。 An object of the present invention is to provide an insulated door which can reduce the heat flow rate of the vertical frame of the door and can improve the thermal insulation performance.

本発明の断熱ドアは、上枠および左右の縦枠を備えるドア枠と、前記ドア枠に対して開閉可能に取り付けられる扉とを備え、前記ドア枠の縦枠は、金属製の室外側部材と、中空部を備えて構成されて前記室外側部材に連結される樹脂製の室内側部材と、前記室内側部材に設けられた樹脂製の戸当り部材とを備え、前記扉は、４本の骨材からなる枠体と、前記枠体の室外面に配置された室外面材と、前記枠体の室内面に配置された室内面材と、前記室外面材および前記室内面材間に配置された断熱芯材と、前記枠体の外周側に配置されたエッジ材とを備え、室内外の熱流通を低減する断熱層が設けられた断熱扉であり、前記各骨材は、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補強材とを備え、前記補強材および前記エッジ材の金属部品は、前記室内面材から見込み方向に離れて配置され、前記断熱層は、前記室内面材の裏面に沿って形成されていることを特徴とする。 Insulation door of the present invention, the upper frame and the door frame with the left and right vertical frame, and a door attached to be openable and closable with respect to the door frame, the vertical frame of the front SL door frame is made of metal outdoor A door, a resin-made indoor side member having a hollow portion and connected to the outdoor side member, and a resin-made door contact member provided on the indoor side member ; Between a frame consisting of a book aggregate, a room outer surface material arranged on the room outer surface of the frame body, a room surface material arranged on the room surface of the frame, the room outer surface material and the room surface material It is a heat insulation door provided with the heat insulation core material arrange | positioned in, and the edge material arrange | positioned at the outer peripheral side of the said frame, and the heat insulation layer which reduces heat distribution indoors and outdoors was provided, Each said aggregate is A resin aggregate made of resin and a metal reinforcement disposed on the inner peripheral side of the resin aggregate; Metal parts of di-member is arranged apart expected direction from said chamber surface material, the heat insulation layer, characterized that you have been formed along the rear surface of the indoor surface material.

本発明によれば、金属製の室外側部材に樹脂製の室内側部材を連結して縦枠を構成したので、金属製の室外側部材が室内空間に露出することがない。特に、室内側部材は、中空部を備えているため、断熱性を向上でき、縦枠における室内空間から室外空間への熱流出量を低減でき、断熱性能を向上できる。
また、戸当り部材が金属製の室外側部材に取り付けられていると、戸当り部材を保持する金属部分から熱流出して断熱性能が低下するが、本発明では、戸当り部材を樹脂製の室内側部材に設けているので、戸当り部材を保持する部分からの熱流出を低減できて断熱性能を向上できる。
従って、扉を閉めて戸当り部材が扉内面に当接した状態では、扉の断熱層と、前記戸当り部材および室内側部材とによって、断熱ドアの室内面において連続する断熱ラインを形成できるため、熱流出を効果的に抑制でき、断熱性能を向上できる。
また、金属製の補強材やエッジ材を室内面材から見込み方向に離して配置することで、室内面材に沿って金属部品が存在しない領域を設けることができ、この領域に断熱層を形成できる。このため、扉の辺縁部に配置される補強材やエッジ材に熱伝導率の高い金属材を使用していても、これらの金属製の補強材やエッジ材は室内面材から離れて配置されるため、これらの部品が熱橋となることを防止でき、扉の断熱性能も向上できる。 According to the present invention, since the indoor side member made of resin is connected to the indoor side member made of metal to constitute the vertical frame, the metal outdoor side member is not exposed to the indoor space. In particular, since the indoor side member includes the hollow portion, the heat insulation can be improved, the amount of heat flowing out from the indoor space to the outdoor space in the vertical frame can be reduced, and the heat insulation performance can be improved.
In addition, when the door contact member is attached to the metal outdoor side member, heat flows out from the metal portion that holds the door contact member and the heat insulation performance decreases. However, in the present invention, the door contact member is a resin chamber Since it is provided in the inner member, the heat outflow from the portion holding the door contact member can be reduced, and the heat insulation performance can be improved.
Therefore, when the door is closed and the door contact member contacts the inner surface of the door, the heat insulating layer of the door and the door contact member and the indoor side member can form a continuous heat insulating line on the indoor surface of the heat insulating door. The heat outflow can be effectively suppressed, and the heat insulation performance can be improved.
Further, by arranging the metal reinforcing material and the edge material away from the indoor surface material in the prospective direction, it is possible to provide a region where no metal parts exist along the indoor surface material, and a heat insulating layer is formed in this region it can. For this reason, even if a metal material with high thermal conductivity is used as a reinforcing material or edge material disposed at the edge of the door, these metal reinforcing materials or edge materials are disposed away from the indoor facing material Therefore, these parts can be prevented from becoming a thermal bridge, and the heat insulation performance of the door can also be improved.

本発明の断熱ドアにおいて、前記室内側部材の中空部内には、断熱材が配置されていることが好ましい。
室内側部材の中空部に断熱材を配置すれば、中空部が空気層の場合に比べて、室内側部材の断熱性能をさらに向上でき、縦枠の熱流量をより低減できてドアの断熱性能も向上できる。
さらに、室内側部材に中空部を形成しているので、この中空部への断熱材の配置の有無や、配置する断熱材の種類によって、縦枠の断熱性能を容易に調整できる。 In the heat insulating door of the present invention, it is preferable that a heat insulating material be disposed in the hollow portion of the indoor side member.
If the heat insulating material is disposed in the hollow portion of the indoor side member, the heat insulating performance of the indoor side member can be further improved as compared with the case where the hollow portion is an air layer, and the heat flow of the vertical frame can be further reduced. Can also be improved.
Furthermore, since the hollow portion is formed in the indoor side member, the heat insulation performance of the vertical frame can be easily adjusted by the presence or absence of the arrangement of the heat insulator in the hollow portion and the type of the heat insulator to be arranged.

本発明の断熱ドアにおいて、前記樹脂骨材は、前記室外面材に密着する室外片部と、前記室内面材に密着する室内片部と、前記室外片部および室内片部間を連結する見込み片部とを備え、前記補強材は前記室内片部から室外側に離れた位置に配置され、前記補強材および前記室内片部間には断熱材が配置されていることが好ましい。 In the heat insulation door according to the present invention, the resin aggregate is expected to connect the outdoor piece to be in close contact with the outdoor surface material, the indoor piece to be in close contact with the indoor surface material, and the outdoor piece and the indoor piece to be connected. Preferably, the reinforcing member is disposed at a position away from the indoor piece portion to the outer side, and a heat insulating material is disposed between the reinforcing member and the indoor piece portion.

本発明によれば、樹脂骨材の室内片部と、金属製の補強材との間に断熱材を配置しているので、樹脂骨材の室内片部と、補強材との間を空気層とした場合に比べて、扉の断熱性能をさらに向上できる。 According to the present invention, since the heat insulating material is disposed between the indoor piece portion of the resin aggregate and the metal reinforcing member, the air layer is formed between the indoor piece portion of the resin aggregate and the reinforcing member. The heat insulation performance of the door can be further improved as compared with the case of.

本発明の断熱ドアにおいて、前記縦枠は、前記扉の見込み面に当接する樹脂製の気密材を備え、前記扉を閉めた状態では、前記戸当り部材および前記気密材で区画される空気層が形成されることが好ましい。 In the heat insulation door according to the present invention, the vertical frame includes a resin airtight material in contact with a prospective surface of the door, and in a state where the door is closed, an air layer divided by the door contact member and the air tight material. Is preferably formed.

本発明によれば、縦枠と扉との隙間において、戸当り部材の室外側に気密材が配置され、これら戸当り部材および気密材の間に密閉空気層が形成されるため、戸当り部材が外気に直接晒されることを防止できる。このため、戸当り部材の熱損失を抑制でき、断熱性能を向上できる。 According to the present invention, in the gap between the vertical frame and the door, the airtight material is disposed on the outside of the door contact member, and a closed air layer is formed between the door contact member and the airtight member. Can be prevented from being exposed directly to the open air. For this reason, the heat loss of a door-contacting member can be suppressed, and heat insulation performance can be improved.

本発明の断熱ドアにおいて、前記ドア枠の上枠は、金属製の室外側部材と、中空部を備えて構成されて前記室外側部材に連結される樹脂製の室内側部材と、前記室内側部材に設けられた樹脂製の戸当り部材とを備え、前記室内側部材の中空部には断熱材が配置されていることが好ましい。 In the heat insulating door according to the present invention, the upper frame of the door frame includes a metallic outdoor side member, a hollow portion and a resin indoor side member configured to be connected to the outdoor side member, and the indoor side. It is preferable that a door contact member made of resin is provided on the member, and a heat insulating material is disposed in the hollow portion of the indoor side member.

本発明によれば、縦枠と同様に、中空部を備える室内側部材を金属製の室外側部材に連結しているので、熱伝導率の高い金属製の室外側部材が室内空間に露出せず、室内側部材の断熱性能も向上でき、室内空間から室外空間への熱流出量を低減でき、断熱性能を向上できる。
また、室内側部材の中空部に断熱材を配置しているので、中空部が空気層の場合に比べて、室内側部材の断熱性能をさらに向上できる。
さらに、戸当り部材を樹脂製の室内側部材に設けているので、戸当り部材を保持する部分からの熱流出を低減できて断熱性能を向上できる。
従って、扉を閉めて戸当り部材が扉内面に当接した状態では、扉の断熱層と、前記戸当り部材および室内側部材とによって、断熱ドアの上枠部分から扉に跨がって連続する断熱ラインを形成できるため、熱流出を効果的に抑制でき、断熱性能を向上できる。 According to the present invention, as in the case of the vertical frame, since the indoor side member having the hollow portion is connected to the metal outdoor side member, the metal outdoor side member having high thermal conductivity is exposed to the indoor space. In addition, the heat insulation performance of the indoor side member can be improved, the amount of heat flow from the indoor space to the outdoor space can be reduced, and the heat insulation performance can be improved.
Moreover, since the heat insulating material is disposed in the hollow portion of the indoor side member, the heat insulating performance of the indoor side member can be further improved as compared with the case where the hollow portion is an air layer.
Furthermore, since the door contact member is provided on the indoor side member made of resin, the heat outflow from the portion holding the door contact member can be reduced, and the heat insulation performance can be improved.
Therefore, when the door is closed and the door contact member is in contact with the inner surface of the door, the heat insulating layer of the door and the door contact member and the indoor side member continuously straddle the door from the upper frame portion of the heat insulating door. Since the heat insulation line can be formed, heat outflow can be effectively suppressed and the heat insulation performance can be improved.

本発明の断熱ドアにおいて、前記上枠の室内側部材には、前記扉の上面側に突出するヒレ部が設けられ、前記扉を閉めた状態では、前記ヒレ部と、前記上枠の戸当り部材との間に空気層が形成されることが好ましい。 In the heat insulating door according to the present invention, the indoor side member of the upper frame is provided with a fin portion projecting to the upper surface side of the door, and in the state where the door is closed, the fin portion and the door contact of the upper frame Preferably, an air layer is formed between the members.

本発明によれば、上枠と扉上面との隙間において、戸当り部材の室外側にヒレ部が配置されて空気層が形成されるため、戸当り部材が外気に直接晒されることを抑制できる。このため、上枠における戸当り部材の熱損失を抑制でき、断熱性能を向上できる。
なお、下枠と扉下面との隙間にもヒレ部を配置して、戸当り部材の室外側に空気層を形成してもよい。この場合、下枠における戸当り部材の熱損失も抑制でき、断熱性能を向上できる。 According to the present invention, in the gap between the upper frame and the upper surface of the door, the fin portion is disposed on the outer side of the door contact member to form an air layer, so direct exposure of the door contact member to the outside air can be suppressed. . For this reason, the heat loss of the door contact member in an upper frame can be suppressed, and heat insulation performance can be improved.
In addition, a fin may be arrange | positioned also in the clearance gap between a lower frame and a door lower surface, and an air layer may be formed in the outdoor side of a door stop member. In this case, the heat loss of the door contact member in the lower frame can also be suppressed, and the heat insulation performance can be improved.

本発明によれば、断熱ドアにおいて縦枠の熱流量を低減できて断熱性能を向上できる。 According to the present invention, the heat flow rate of the vertical frame can be reduced in the heat insulation door, and the heat insulation performance can be improved.

以下、本発明の実施形態を図面に基づいて説明する。
図１，２に、本発明の断熱ドアの第１実施形態である玄関ドア（以下、ドア１と略称）を示す。ドア１は、いわゆる片開きドアであり、建物の外壁開口部に固定されるドア枠２と、このドア枠２に開閉自在に支持される扉５とを備えて構成されている。 Hereinafter, embodiments of the present invention will be described based on the drawings.
1 and 2 show an entrance door (hereinafter referred to as door 1) which is a first embodiment of the heat insulation door of the present invention. The door 1 is a so-called single-opening door, and includes a door frame 2 fixed to an opening of an outer wall of a building and a door 5 supported by the door frame 2 so as to be openable and closable.

［ドア枠の構成］
ドア枠２は、図３，４にも示すように、上枠１０、下枠２０および左右の縦枠３０，４０を有する。なお、図１の右側に配置される縦枠３０が吊元側とされて丁番４が取り付けられ、図１の左側に配置される縦枠４０が戸先側とされている。 [Structure of door frame]
The door frame 2 has an upper frame 10, a lower frame 20, and left and right vertical frames 30, 40, as also shown in FIGS. The vertical frame 30 disposed on the right side of FIG. 1 is the hanging side, the hinge 4 is attached, and the vertical frame 40 disposed on the left side of FIG. 1 is the door tip side.

上枠１０は、図５にも示すように、室外側部材１１と、室内側部材１３と、ＡＴ材（エアータイト材、気密材）としても機能する戸当り部材１５と、水密材１８とを備える。
室外側部材１１は、アルミ押出形材からなる室外部材１１１および室内部材１１２を、ウレタン樹脂等の断熱部材１１３で連結して構成されたアルミ断熱形材で構成されている。 The upper frame 10, as also shown in FIG. 5, includes an outdoor side member 11, an indoor side member 13, a door contact member 15 which also functions as an AT material (air tight material, airtight material), and a water tight material 18. Prepare.
The outdoor side member 11 is made of an aluminum thermal insulation material formed by connecting an outdoor member 111 and an indoor member 112 made of an extruded aluminum material by a heat insulating member 113 such as urethane resin.

室内側部材１３は、ＥＰＤＭ（エチレンプロピレンゴム）やＰＶＣ（ポリ塩化ビニル）などの樹脂製であり、室外側部材１１に連結されている。本実施形態では、室内側部材１３は、室外側部材１１を介して躯体にねじ込まれるネジによって、室外側部材１１に連結されている。これにより、室内側部材１３は、扉５を閉めた際に室外側部材１１において室内側に露出する面を被覆し、室外側部材１１が室内空間に露出しないようにしている。
室内側部材１３は、中空部（ホロー部）１３１と、戸当り部材１５が装着される装着溝１３２と、ヒレ部１３３とを備える。中空部１３１は、室内側部材１３において略矩形枠状に形成された部分で構成されている。この中空部１３１内には、フェノール樹脂やＥＰＳ（発泡ビーズ法ポリスチレン）等で構成される断熱材１４１が配置されている。
室内側部材１３は、室内部材１１２および断熱部材１１３の下面全体を覆い、さらに室外部材１１１において断熱部材１１３に隣接する下面部分を覆っている。室内側部材１３の室外側の端部には、斜め下方つまり扉５上面側に向かって、前記ヒレ部１３３が突出されている。 The indoor side member 13 is made of a resin such as EPDM (ethylene propylene rubber) or PVC (polyvinyl chloride), and is connected to the outdoor side member 11. In the present embodiment, the indoor side member 13 is connected to the outdoor side member 11 by a screw that is screwed into the housing via the outdoor side member 11. Thereby, when the door 5 is closed, the indoor side member 13 covers the surface exposed to the indoor side in the outdoor side member 11 so that the outdoor side member 11 is not exposed to the indoor space.
The indoor side member 13 includes a hollow portion (hollow portion) 131, a mounting groove 132 in which the door contact member 15 is mounted, and a fin portion 133. The hollow portion 131 is formed of a portion of the indoor side member 13 formed in a substantially rectangular frame shape. In the hollow portion 131, a heat insulating material 141 composed of a phenol resin, an EPS (foamed bead polystyrene) or the like is disposed.
The indoor side member 13 covers the entire lower surface of the indoor member 112 and the heat insulating member 113, and further covers the lower surface portion adjacent to the heat insulating member 113 in the outdoor member 111. At the end of the outdoor side of the indoor side member 13, the fin portion 133 protrudes obliquely downward, that is, toward the upper surface side of the door 5.

戸当り部材１５は、ＥＰＤＭ（エチレンプロピレンゴム）やＰＶＣ（ポリ塩化ビニル）などの樹脂製であり、扉５を閉めた際に扉５の室内面に当接する。この際、扉５の上面と上枠１０間の隙間部分には、前記ヒレ部１３３および戸当り部材１５で空間が区画され、空気層１６が形成される。この空気層１６は、前記ヒレ部１３３が扉５上面から離れているため、完全に密閉された空間ではないが、ヒレ部１３３が設けられていることで、外気の流入が抑制された空気層とされている。
水密材１８は、室外側部材１１の室外側端部に設けられ、室外側部材１１および扉５間の隙間への雨水の吹き込みを低減する。 The door stop member 15 is made of resin such as EPDM (ethylene propylene rubber) or PVC (polyvinyl chloride), and abuts on the indoor surface of the door 5 when the door 5 is closed. At this time, in the clearance between the upper surface of the door 5 and the upper frame 10, a space is divided by the fin portion 133 and the door contact member 15, and an air layer 16 is formed. The air layer 16 is not a completely sealed space because the fins 133 are separated from the upper surface of the door 5, but the air layer 16 is provided so that the inflow of outside air is suppressed. It is assumed.
The watertight material 18 is provided at the outdoor end of the outdoor member 11 to reduce the injection of rainwater into the gap between the outdoor member 11 and the door 5.

下枠２０は、図５にも示すように、室外側部材２１と、カバー部材２３と、ＡＴ材としても機能する戸当り部材２５とを備える。下枠２０は、モルタルで納まるため、熱の出入りが少ない。このため、室外側部材２１は、室外側部材１１のようにアルミ断熱形材で構成する必要が無いため、アルミ押出形材で構成されている。
室外側部材２１には、前記カバー部材２３が装着される溝部と、戸当り部材２５が装着される溝部とが形成されている。
カバー部材２３は、ＥＰＤＭやＰＶＣなどの樹脂製であり、室外側部材２１において、戸当り部材２５よりも室内側の露出面を被覆している。
戸当り部材２５は、戸当り部材１５と同一の部品であり、扉５を閉めた際に扉５の室内面に当接する。
したがって、下枠２０の室外側部材２１の室内露出面は、カバー部材２３および戸当り部材２５で被覆されている。 The lower frame 20 is provided with the outdoor side member 21, the cover member 23, and the door contact member 25 which also functions as an AT material, as shown also in FIG. The lower frame 20 is filled with mortar, so there is little heat inflow. For this reason, since the outdoor side member 21 does not need to be comprised with an aluminum heat insulation profile like the outdoor side member 11, it is comprised by the aluminum extrusion shape.
The outdoor side member 21 is formed with a groove portion to which the cover member 23 is attached and a groove portion to which the door contact member 25 is attached.
The cover member 23 is made of resin such as EPDM or PVC, and covers the exposed surface on the indoor side of the door contact member 25 in the outdoor side member 21.
The door stop member 25 is the same component as the door stop member 15 and abuts on the indoor surface of the door 5 when the door 5 is closed.
Therefore, the indoor exposed surface of the outdoor side member 21 of the lower frame 20 is covered with the cover member 23 and the door contact member 25.

なお、本実施形態では、下枠２０および扉５の下面間の隙間部分において、戸当り部材２５の室外側には、ヒレ部１３３のようなヒレ部材は設けられていない。そこで、扉５の下面から下枠２０に向かって突出するヒレ部を形成し、ヒレ部および戸当り部材２５間に空気層を形成してもよい。 In the present embodiment, in the gap between the lower frame 20 and the lower surface of the door 5, no fin member such as the fin portion 133 is provided on the outdoor side of the door contact member 25. Therefore, a fin portion protruding toward the lower frame 20 from the lower surface of the door 5 may be formed, and an air layer may be formed between the fin portion and the door contact member 25.

吊元側の縦枠３０は、図６にも示すように、室外側部材３１と、室内側部材３３と、ＡＴ材としても機能する戸当り部材３５と、ＡＴ材３７と、水密材３８とを備える。

第１室内側部材３３１は、室内部材３１２の露出面を被覆するベース材であり、戸当り部材３５が装着される装着溝３３２も形成されている。この第１室内側部材３３１は、図４に示すように、室内部材３１２を介して躯体にねじ込まれるネジ３３３によって、室内部材３１２と共に躯体に固定されている。
第１室内側部材３３１に装着される戸当り部材３５は、ＥＰＤＭやＰＶＣなどの樹脂製であり、図６に示すように、扉５を閉めた際に扉５の室内面に当接する。 The indoor side member 33 is composed of two indoor side members, a first indoor side member 331 and a second indoor side member 335. Each indoor side member 331, 335 is comprised with resin members, such as EPDM and PVC, and when the door 5 is closed, it covers the surface exposed to the indoor side in the outdoor side member 31. As shown in FIG.
The first indoor side member 331 is a base material that covers the exposed surface of the indoor member 312, and a mounting groove 332 in which the door contact member 35 is mounted is also formed. As shown in FIG. 4, the first indoor side member 331 is fixed to the housing together with the indoor member 312 by a screw 333 screwed into the housing via the indoor member 312.
The door contact member 35 attached to the first indoor side member 331 is made of resin such as EPDM or PVC, and as shown in FIG. 6, contacts the indoor surface of the door 5 when the door 5 is closed.

第２室内側部材３３５は、前記ネジ３３３を被覆するものであり、第１室内側部材３３１に係合する２つの係合片３３６と、この係合片３３６に連結する略矩形枠状の中空部（ホロー部）３３７と、第１室内側部材３３１の装着溝３３２部分を被覆する被覆片３３８とを備えている。
第２室内側部材３３５において、前記２つの係合片３３６間と、中空部３３７とには、それぞれフェノール樹脂やＥＰＳ等を用いた断熱材３４１，３４２が配置されている。 The second indoor side member 335 covers the screw 333 and has two engagement pieces 336 engaged with the first indoor side member 331 and a substantially rectangular frame-like hollow connected with the engagement piece 336.

For this reason, since the door 5 is not a special structure for improving heat insulation performance, it can be easily manufactured by conventional manufacturing equipment and quality.
Furthermore, the heat insulation performance of the door 5 can be easily adjusted by replacing the heat insulation core material 68 with a heat insulation core material having a different heat insulation performance grade.
(6) Furthermore, since the heat insulating material 63 is disposed between the indoor piece portion 613 of the resin aggregate 61 and the metal reinforcing material 62 in the door 5, the air layer is not disposed. The heat insulation performance of the door 5 can be easily improved as compared with the case of.
Moreover, since the metal reinforcing member 62 is included in the frame 60, it is possible to easily equip with standard functional components provided on the door 1 such as the hinge 4 and the lock case.

（７）縦枠３０、４０に、戸当り部材３５，４５と、ＡＴ材３７，４７との２つのＡＴ材を配置し、２つのＡＴ材間に密閉空気層３９，４９を形成しているので、戸当り部材３５，４５が外気に直接晒されることを防止できる。このため、戸当り部材３５，４５の熱損失を抑制でき、断熱性能を向上できる。
また、上枠１０の室内側部材１３にヒレ部１３３を形成したので、ヒレ部１３３と戸当り部材１５の間にも空気層１６を形成でき、上枠１０においても戸当り部材１５の熱損失を抑制でき、断熱性能を向上できる。さらに、扉５の上面にヒレ部を設けた場合には、扉５の上面に浸入した雨水を室外側に排水し難くなるが、上枠１０側にヒレ部１３３を設けたので、浸入した水がヒレ部１３３で停滞することを防止できる。 (7) Two AT materials, door contact members 35 and 45 and AT materials 37 and 47, are disposed in the vertical frames 30 and 40, and a closed air layer 39 or 49 is formed between the two AT materials. Therefore, the door contacts 35 and 45 can be prevented from being exposed directly to the outside air. Therefore, the heat loss of the door contact members 35 and 45 can be suppressed, and the heat insulation performance can be improved.
Further, since the fin portion 133 is formed on the indoor side member 13 of the upper frame 10, the air layer 16 can be formed also between the fin portion 133 and the door stop member 15, and the heat loss of the door stop member 15 also in the upper frame 10. Can be suppressed and the heat insulation performance can be improved. Furthermore, when the fin portion is provided on the upper surface of the door 5, it is difficult to drain the rainwater invading the upper surface of the door 5 to the outside, but since the fin portion 133 is provided on the upper frame 10 side Can be prevented from stagnating in the fin portion 133.
