Description

本発明は、建物の玄関、勝手口等に用いられる戸体および建具に関する。 The present invention relates to a door body and fittings used for a building entrance, a kitchen door, and the like.

玄関ドア等の建具に用いられる扉などの戸体は、芯材の外周にスチール製の力骨を組み付け、芯材と力骨の室内面に内鋼板を接着し、屋外面に外鋼板を接着したパネル体が一般的である。このパネル体は、スチール製の力骨が芯材の四周に配置されるために重量が増加し、部品点数も増えるという課題がある。
そこで、力骨を省略し、外鋼板および内鋼板の一方の見込面に凹条を形成し、他方の見込面に凸条を形成し、各見込面を重ね合わせて凹条および凸条を嵌合させ、さらにリベットで各見込面同士を固定したパネル体が開発されている（特許文献１）。 For doors and other doors used for fittings such as entrance doors, steel braids are attached to the outer circumference of the core material, inner steel plates are glued to the inner surface of the core material and ribs, and outer steel plates are glued to the outdoor surface. The panel body is generally used. This panel body has a problem that the weight is increased and the number of parts is also increased because the steel braces are arranged around the four circumferences of the core material.
Therefore, omitting the rivet, forming a recess on one prospective surface of the outer steel plate and the inner steel plate, forming a ridge on the other prospective surface, and fitting each prospective surface on top of each other. A panel body has been developed in which the prospective surfaces are fixed to each other with rivets (Patent Document 1).

Further, since the heat insulating member is arranged between the outdoor finding surface portion of the outdoor surface material and the indoor finding surface portion of the indoor surface material , it is possible to prevent the outdoor surface material and the indoor surface material from coming into direct contact with each other. Therefore, the contact portion between the outdoor surface material and the indoor surface material and the portion that becomes a thermal bridge such as an aggregate can be eliminated from the door body, and the heat insulating performance of the door body can be improved.
Further, since the outdoor finding surface portion and the indoor finding surface portion arranged so as to sandwich the heat insulating member are fastened by the fastening member, the distance between the outdoor finding surface portion and the indoor finding surface portion in the prospective direction can be set by the fastening member. Therefore, the heat insulating member can be fastened in a state of being appropriately compressed at the outdoor finding surface portion and the indoor finding surface portion, and the outdoor finding surface portion and the indoor finding surface portion can be fastened without rattling.

本発明の戸体において、前記締結部材は、前記断熱部材が配置された位置で前記屋外見付け面部および前記屋内見付け面部を締結することが好ましい。
本発明によれば、締結部材は断熱部材が配置された位置で屋外見付け面部および屋内見付け面部を締結する。このため、ネジなどの締結部材によって、屋外見付け面部および屋内見付け面部が近接した場合でも断熱部材が介在されているので、屋外見付け面部および屋内見付け面部が接触することを確実に防止できる。 In the door body of the present invention, it is preferable that the fastening member fastens the outdoor finding surface portion and the indoor finding surface portion at a position where the heat insulating member is arranged.
According to the present invention, the fastening member fastens the outdoor finding surface portion and the indoor finding surface portion at the position where the heat insulating member is arranged.

なお、屋内見付け面部５２３Ａ、５２３Ｂの延出寸法（Ｙ軸方向の寸法）は、延長部５１２Ａ、５１２Ｂの延出寸法よりも短くされている。また、屋内見付け面部５２３Ａ、５２３Ｂは、鋼板を折り返して形成されており、鋼板２枚の厚さ寸法とされている。 The indoor surface material 52 includes an indoor surface portion 521 bonded to the indoor surface of the heat insulating core material 53, and peripheral portions 520A to 520D provided around the indoor surface portion 521.
As shown in FIG. 2, the upper and lower peripheral edges 520A and 520B of the indoor surface member 52 are formed continuously from the upper and lower edge edges of the indoor surface member 521 and are formed on the outdoor side along the upper and lower surfaces of the heat insulating core member 53. From the outer peripheral surface portions 522A and 522B, the indoor finding surface portions 523A and 523B extending upward and downward from the outer peripheral surface portions 522A and 522B, and the indoor finding surface portions 523A and 523B to the upper and lower surfaces of the heat insulating core material 53. It is provided with an indoor prospective surface portion 524A and 524B extending along the outdoor side.
The extension dimensions (dimensions in the Y-axis direction) of the indoor finding surface portions 523A and 523B are shorter than the extension dimensions of the extension portions 512A and 512B. Further, the indoor finding surface portions 523A and 523B are formed by folding back steel plates, and have a thickness dimension of two steel plates.

図３に示すように、屋内面部５２１の吊元側の周縁部５２０Ｃは、屋内面部５２１の吊元側の端縁から断熱芯材５３の側面に沿って屋外側に折曲された外周面部５２２Ｃと、外周面部５２２Ｃから縦枠３０側に延長された屋内見付け面部５２３Ｃと、屋内見付け面部５２３Ｃから断熱芯材５３の側面に沿って屋外側に延長された屋内見込み面部５２４Ｃとを備えている。屋内見付け面部５２３Ｃは、屋内見付け面部５２３Ａ、５２３Ｂと同じく、鋼板を折り返して形成されており、鋼板２枚の厚さ寸法とされている。したがって、周縁部５２０Ｃは、周縁部５２０Ａ、５２０Ｂと同様に構成されている。 As shown in FIG. 3, the peripheral edge portion 520C on the hanging side of the indoor surface portion 521 is the outer peripheral surface portion 522C bent from the edge of the indoor surface portion 521 on the hanging side to the outdoor side along the side surface of the heat insulating core material 53. An indoor finding surface portion 523C extending from the outer peripheral surface portion 522C to the vertical frame 30 side, and an indoor prospective surface portion 524C extending from the indoor finding surface portion 523C to the outdoor side along the side surface of the heat insulating core material 53 are provided. Like the indoor finding surface portions 523A and 523B, the indoor finding surface portion 523C is formed by folding back a steel plate, and has a thickness dimension of two steel plates. Therefore, the peripheral edge portion 520C is configured in the same manner as the peripheral edge portions 520A and 520B.

図３に示すように、屋内面部５２１の戸先側の周縁部５２０Ｄは、屋内面部５２１の戸先側の端縁から断熱芯材５３の側面に沿って屋外側に折曲された外周面部５２２Ｄと、外周面部５２２Ｄから縦枠４０側に延長された屋内見付け面部５２３Ｄとを備えている。
このため、周縁部５２０Ｄは、屋内見付け面部５２３Ｄの端縁が屋内面材５２の端縁とされており、屋内見付け面部５２３Ｃのように鋼板が折り返されて構成されていない点と、このために周縁部５２０Ａ〜５２０Ｃの屋内見込み面部５２４Ａ〜５２４Ｃに対応する部分を備えていない点で、周縁部５２０Ａ〜５２０Ｃと相違する。なお、屋外面材５１、屋内面材５２は、縦長に形成されているため、左右の周縁部５１０Ｃ、５１０Ｄ、５２０Ｃ、５２０Ｄは、屋外面材５１、屋内面材５２の長手方向（上下方向）に沿った周縁部である。 As shown in FIG. 3, the peripheral edge portion 520D on the door end side of the indoor surface portion 521 is the outer peripheral surface portion 522D bent from the edge of the indoor surface portion 521 on the door end side to the outdoor side along the side surface of the heat insulating core material 53. And an indoor finding surface portion 523D extending from the outer peripheral surface portion 522D to the vertical frame 40 side.
For this reason, the peripheral edge portion 520D has an edge of the indoor finding surface portion 523D as the edge of the indoor facing member 52, and is not configured by folding the steel plate like the indoor finding surface portion 523C. It differs from the peripheral portions 520A to 520C in that the peripheral portions 520A to 520C do not have a portion corresponding to the indoor prospective surface portions 524A to 524C. Since the outdoor surface material 51 and the indoor surface material 52 are formed vertically, the left and right peripheral edges 510C, 510D, 520C, and 520D are in the longitudinal direction (vertical direction) of the outdoor surface material 51 and the indoor surface material 52. It is a peripheral part along the line.

図２〜４に示すように、扉５の外周面の屋内側端部、つまり扉５においてドア枠２の見込み面に対向する見込み面と、屋内面材５２に沿った屋内面とが交差する角部には、前記屋内面材５２の外周面部５２２Ａ〜５２２Ｄと、屋内見付け面部５２３Ａ〜５２３Ｄとで区画される凹部（段部）５７が形成されている。 As shown in FIGS. 2 to 4, the indoor end of the outer peripheral surface of the door 5, that is, the prospective surface of the door 5 facing the prospective surface of the door frame 2 intersects with the indoor surface along the indoor surface material 52. At the corners, recesses (steps) 57 are formed which are partitioned by the outer peripheral surface portions 522A to 522D of the indoor surface material 52 and the indoor finding surface portions 523A to 523D.

屋外面材５１と、屋内面材５２とは、屋外見付け面部５１４Ａ〜５１４Ｄと、屋内見付け面部５２３Ａ〜５２３Ｄとを、締結部材であるリベット６５で直接締結している。このため、本実施形態では、屋外見付け面部５１４Ａ〜５１４Ｄが屋外面材５１の締結面部であり、屋内見付け面部５２３Ａ〜５２３Ｄが屋内面材５２の締結面部である。なお、屋外見付け面部５１４Ａ〜５１４Ｄに裏板を設けて、屋外面材５１および屋内面材５２をネジを用いて締結してもよい。 The outdoor surface material 51 and the indoor surface material 52 directly fasten the outdoor finding surface portions 514A to 514D and the indoor finding surface portions 523A to 523D with rivets 65, which are fastening members. Therefore, in the present embodiment, the outdoor finding surface portions 514A to 514D are the fastening surface portions of the outdoor surface material 51, and the indoor finding surface portions 523A to 523D are the fastening surface portions of the indoor surface material 52. A back plate may be provided on the outdoor finding surface portions 514A to 514D, and the outdoor surface material 51 and the indoor surface material 52 may be fastened with screws.

屋外見付け面部５１４Ａ〜５１４Ｄと、屋内見付け面部５２３Ａ〜５２３Ｄとの間には、断熱部材６０が配置されている。
断熱部材６０は、屋外面材５１および屋内面材５２間での熱伝導を抑制して断熱性を向上できる材質であればよく、ウレタン樹脂等の一般的な断熱材でもよいし、不燃性ポリウレタン等の不燃性を有する断熱材でもよい。
断熱部材６０は、屋外見付け面部５１４Ａ〜５１４Ｄおよび屋内見付け面部５２３Ａ〜５２３Ｄをリベット６５で締結した際に、屋外面材５１および屋内面材５２が直接接触することを防止できるように構成されている。このため、断熱部材６０は、少なくともリベット６５の締結箇所に配置されていればよく、ピース状の断熱部材を、間隔を空けて複数個配置してもよいが、本実施形態では、長尺の断熱部材６０として形成されている。そのため、断熱部材６０は、屋外見付け面部５１４Ａ〜５１４Ｄおよび屋内見付け面部５２３Ａ〜５２３Ｄ間の全長に渡って配置されている。
また、断熱部材６０は、図４にも示すように、屋外見付け面部５１４Ａ〜５１４Ｄの端縁が当接される突起部６１を備えている。突起部６１は、屋外見付け面部５１４Ａ〜５１４Ｄの端縁と、屋内見込み面部５２４Ａ〜５２４Ｃとの間に配置され、屋外見付け面部５１４Ａ〜５１４Ｄが屋内見込み面部５２４Ａ〜５２４Ｃと直接接触しないように構成している。 A heat insulating member 60 is arranged between the outdoor finding surface portions 514A to 514D and the indoor finding surface portions 523A to 523D.
The heat insulating member 60 may be any material that can suppress heat conduction between the outdoor surface material 51 and the indoor surface material 52 to improve heat insulating properties, and may be a general heat insulating material such as urethane resin or nonflammable polyurethane. It may be a heat insulating material having nonflammability such as.
The heat insulating member 60 is configured to prevent the outdoor surface material 51 and the indoor surface material 52 from coming into direct contact with each other when the outdoor finding surface portions 514A to 514D and the indoor finding surface portions 523A to 523D are fastened with rivets 65. .. Therefore, the heat insulating member 60 may be arranged at least at the fastening portion of the rivet 65, and a plurality of piece-shaped heat insulating members may be arranged at intervals. However, in the present embodiment, the heat insulating member 60 is long. It is formed as a heat insulating member 60. Therefore, the heat insulating member 60 is arranged over the entire length between the outdoor finding surface portions 514A to 514D and the indoor finding surface portions 523A to 523D.
Further, as shown in FIG. 4, the heat insulating member 60 includes a protrusion 61 to which the end edges of the outdoor finding surface portions 514A to 514D are brought into contact with each other. The protrusion 61 is arranged between the edge of the outdoor finding surface portions 514A to 514D and the indoor prospective surface portions 524A to 524C, and is configured so that the outdoor finding surface portions 514A to 514D do not come into direct contact with the indoor prospective surface portions 524A to 524C. ing.

したがって、屋外見付け面部５１４Ａ〜５１４Ｄ、断熱部材６０、屋内見付け面部５２３Ａ〜５２３Ｄには、見込み方向に貫通する貫通穴が所定間隔で形成され、貫通穴に挿通されるリベット６５により屋外面材５１および屋内面材５２は、断熱部材６０を介在して締結されている。また、リベット６５によって規制される屋外見付け面部５１４Ａ〜５１４Ｄと、屋内見付け面部５２３Ａ〜５２３Ｄとの間隔寸法（見込み方向つまりＺ軸方向の寸法）に応じて断熱部材６０の厚さ寸法（Ｚ軸方向の寸法）が設定されている。このため、リベット６５で締結した際に、屋外見付け面部５１４Ａ〜５１４Ｄと、屋内見付け面部５２３Ａ〜５２３Ｄとは、断熱部材６０に隙間無く密着し、屋外見付け面部５１４Ａ〜５１４Ｄ、屋内見付け面部５２３Ａ〜５２３Ｄ間でガタツキが生じないように構成されている。
エッジ材７は、アルミニウムなどの金属製の押出形材で形成され、屋外見込み面部５１３Ｄに図示略のリベットや接着剤などを用いて固定されている。 Therefore, through holes penetrating in the prospective direction are formed at predetermined intervals in the outdoor finding surface portions 514A to 514D, the heat insulating member 60, and the indoor finding surface portions 523A to 523D, and the outdoor surface material 51 and the outdoor surface material 51 and the rivets 65 inserted through the through holes are formed. The indoor surface material 52 is fastened with the heat insulating member 60 interposed therebetween. Further, the thickness dimension (Z-axis direction) of the heat insulating member 60 is determined according to the distance dimension (the dimension in the expected direction, that is, the Z-axis direction) between the outdoor finding surface portions 514A to 514D regulated by the rivet 65 and the indoor finding surface portions 523A to 523D. Dimensions) are set. Therefore, when fastened with the rivet 65, the outdoor finding surface portions 514A to 514D and the indoor finding surface portions 523A to 523D are in close contact with the heat insulating member 60 without a gap, and the outdoor finding surface portions 514A to 514D and the indoor finding surface portions 523A to 523D. It is configured so that there is no rattling between them.
The edge material 7 is formed of an extruded metal material such as aluminum, and is fixed to the outdoor prospective surface portion 513D by using a rivet or an adhesive (not shown).

扉５の周縁部の凹部５７には、樹脂部材８が装着されている。樹脂部材８の形状について、図４を参照して説明する。なお、図４では、錠６は省略している。
樹脂部材８は、屋外面部８１と、屋外面部８１の外周側端部から屋内側に延出されてドア枠２の見込み面（下面部１１３、上面部２１３、側面部３１３、４１３）に対向する見込み面部８２と、保持片部１２２、２２２、３２２、４２２に対向する見付け面部８３と、断面円弧状に形成されて見込み面部８２および見付け面部８３を連結する連結部８４とを備えている。 A resin member 8 is attached to the recess 57 at the peripheral edge of the door 5. The shape of the resin member 8 will be described with reference to FIG. In FIG. 4, the lock 6 is omitted.
The resin member 8 extends from the outer peripheral side end portion of the outdoor surface portion 81 to the indoor side and faces the prospective surfaces (lower surface portion 113, upper surface portion 213, side surface portions 313, 413) of the door frame 2. It includes a prospective surface portion 82, a finding surface portion 83 facing the holding piece portions 122, 222, 222, and 422, and a connecting portion 84 formed in an arc shape in cross section to connect the prospective surface portion 82 and the finding surface portion 83.

屋外面部８１において、断熱部材６０に当接する端部の厚さ寸法（見込み方向の寸法）は、屋外面部８１の他の部分に比べて大きくされている。このため、扉５の上面、下面および吊元側の側面に配置される樹脂部材８の屋外面部８１は、屋外見付け面部５１４Ａ〜５１４Ｃと屋内見付け面部５２３Ａ〜５２３Ｃとの隙間に圧入されている。また、戸先側の側面に配置される樹脂部材８の屋外面部８１は、エッジ材７の屋内側端部と屋内見付け面部５２３Ｄとの間に圧入されている。 The thickness dimension (dimension in the prospective direction) of the end portion of the outdoor surface portion 81 that abuts on the heat insulating member 60 is larger than that of the other portion of the outdoor surface portion 81. Therefore, the outdoor surface portion 81 of the resin member 8 arranged on the upper surface, the lower surface, and the side surface on the hanging side of the door 5 is press-fitted into the gap between the outdoor finding surface portions 514A to 514C and the indoor finding surface portions 523A to 523C. Further, the outdoor surface portion 81 of the resin member 8 arranged on the side surface on the door end side is press-fitted between the indoor side end portion of the edge material 7 and the indoor finding surface portion 523D.

見付け面部８３の屋外面（屋内見付け面部５２３Ａ〜５２３Ｄに対向する面）には、溝８３１が形成されている。この溝８３１に図示略の小口キャップの係止片を差し込むことで、各樹脂部材８は扉５に取り付けられる。 A groove 831 is formed on the outdoor surface of the finding surface portion 83 (the surface facing the indoor finding surface portions 523A to 523D). Each resin member 8 is attached to the door 5 by inserting a locking piece of an edge cap (not shown) into the groove 831.

このような樹脂部材８は、屋外面部８１から見付け面部８３までの見込み方向（Ｚ軸方向）の寸法を、外周面部５２２Ａ〜５２２Ｄの見込み寸法を基準に設定することで、見付け面部８３が屋内面部５２１とほぼ同一面となるように設定されている。このため、屋内面部５２１と見付け面部８３との間には、段差が生じないようにされている。
また、周縁部５２０Ａ〜５２０Ｃに設けられる樹脂部材８は、見込み面部８２から見付け面部８３の先端部までの見付け方向（扉５の上下に設けられる樹脂部材８ではＹ軸方向、吊元側に設けられる樹脂部材８ではＸ軸方向）の寸法を、屋内面材５２の外周面部５２２Ａ〜５２２Ｃから屋外面材５１の屋外見込み面部５１３Ａ〜５１３Ｃまでの寸法を基準に設定することで、見込み面部８２が屋外見込み面部５１３Ａ〜５１３Ｃとほぼ同一面となるように設定されている。このため、屋外見込み面部５１３Ａ〜５１３Ｃと見込み面部８２との間には段差が生じないようにされている。 In such a resin member 8, the finding surface portion 83 is an indoor surface portion by setting the dimension in the expected direction (Z-axis direction) from the outdoor surface portion 81 to the finding surface portion 83 based on the estimated dimensions of the outer peripheral surface portions 522A to 522D. It is set to be substantially on the same surface as 521. Therefore, a step is not generated between the indoor surface portion 521 and the finding surface portion 83.
Further, the resin members 8 provided on the peripheral edges 520A to 520C are provided in the finding direction from the prospective surface portion 82 to the tip end portion of the finding surface portion 83 (the resin members 8 provided above and below the door 5 are provided in the Y-axis direction on the hanging side. By setting the dimensions of the resin member 8 (in the X-axis direction) from the outer peripheral surface portions 522A to 522C of the indoor surface material 52 to the outdoor prospective surface portions 513A to 513C of the outdoor surface material 51, the prospective surface portion 82 can be formed. It is set so as to be substantially the same surface as the outdoor prospective surface portions 513A to 513C. Therefore, a step is not generated between the outdoor prospective surface portions 513A to 513C and the prospective surface portion 82.

このような構成の樹脂部材８は、ポリウレタン樹脂やエポキシ樹脂等に、熱膨張性黒鉛等の熱膨張性材料を混入した熱膨張性樹脂材を押出成形することで製造されたものであり、発泡温度まで加熱されると樹脂部材８の全体が発泡、膨張する。
この際、見込み面部８２は、ドア枠２の見込み面（下面部１１３、上面部２１３、側面部３１３、４１３）に対向して設けられており、ドア枠２の見込み面に向かって発泡する。このため、見込み面部８２によって、第１加熱発泡部が構成されている。
見付け面部８３は、ドア枠２の屋内側見付け面、つまりタイト材１５、２５、３５、４５が取り付けられた保持片部１２２、２２２、３２２、４２２に対向して設けられており、ドア枠２の屋内側見付け面に向かって発泡する。このため、見付け面部８３によって、第２加熱発泡部が構成されている。
連結部８４は、円弧状に湾曲されているため、見込み方向および見付け方向に対して交差する斜め方向に発泡する。このため、連結部８４は、例えば、断熱材１３、３３、４３に向かって発泡する。 The resin member 8 having such a structure is manufactured by extrusion-molding a heat-expandable resin material in which a heat-expandable material such as heat-expandable graphite is mixed with a polyurethane resin, an epoxy resin, or the like, and is foamed. When heated to a temperature, the entire resin member 8 foams and expands.
At this time, the prospective surface portion 82 is provided so as to face the prospective surface (lower surface portion 113, upper surface portion 213, side surface portion 313, 413) of the door frame 2, and foams toward the prospective surface of the door frame 2. Therefore, the prospective surface portion 82 constitutes the first heated foaming portion.
The finding surface portion 83 is provided so as to face the indoor finding surface of the door frame 2, that is, the holding piece portions 122, 222, 222, 422 to which the tight materials 15, 25, 35, 45 are attached, and the door frame 2 Foams toward the indoor side finding surface. Therefore, the second heated foaming portion is formed by the finding surface portion 83.
Since the connecting portion 84 is curved in an arc shape, it foams in an oblique direction intersecting the prospective direction and the finding direction. Therefore, the connecting portion 84 foams toward, for example, the heat insulating materials 13, 33, and 43.

扉５と、ドア枠２との間の防火構造について、扉５の戸先側と縦枠４０との間で樹脂部材８が発泡した状態を示す図５、６を参照して説明する。なお、図５は、扉５の屋外側を加熱して試験を行った屋外側加熱状態であり、図６は、扉５の屋内側を加熱して試験を行った屋内側加熱状態を示す。 The fireproof structure between the door 5 and the door frame 2 will be described with reference to FIGS. 5 and 6 showing a state in which the resin member 8 is foamed between the door end side of the door 5 and the vertical frame 40. Note that FIG. 5 shows an outdoor side heating state in which the outdoor side of the door 5 was heated and tested, and FIG. 6 shows an indoor side heating state in which the indoor side of the door 5 was heated and tested.

図５に示すように、屋外側加熱状態では、屋外面材５１等が熱伸びするため、扉５の上端部や下端部は屋内側に移動するように反る。なお、扉５の上下方向の中間部は、ラッチボルト６Ａやデッドボルトで、ドア枠２に係止されるため、扉５が熱反りした際には、扉５の上下方向中間部は移動せず、上端部や下端部が移動する。
このため、扉５の上端部や下端部は屋内側に移動し、タイト材１５、２５、３５、４５との隙間は熱反りしていない場合に比べて狭くなる。
樹脂部材８が発泡して膨張すると、扉５とドア枠２の見込み面との隙間や、扉５とタイト材１５、２５、３５、４５や保持片部１２２、２２２、３２２、４２２との隙間を、発泡した樹脂部材８が塞ぐ。樹脂部材８は、タイト材１５、２５、３５、４５、断熱材１３、３３、４３、断熱部材６０等も覆うため、タイト材１５、２５、３５、４５や断熱材１３、３３、４３、断熱部材６０が焼失することも防止できる。 As shown in FIG. 5, in the outdoor side heating state, the outdoor surface material 51 and the like heat-extend, so that the upper end portion and the lower end portion of the door 5 warp so as to move to the indoor side. Since the vertical intermediate portion of the door 5 is locked to the door frame 2 by a latch bolt 6A or a dead bolt, the vertical intermediate portion of the door 5 can be moved when the door 5 is thermally warped. Instead, the upper and lower ends move.
Therefore, the upper end portion and the lower end portion of the door 5 move to the indoor side, and the gaps with the tight materials 15, 25, 35, and 45 are narrower than in the case where the door 5 is not warped by heat.
When the resin member 8 foams and expands, the gap between the door 5 and the prospective surface of the door frame 2 and the gap between the door 5 and the tight materials 15, 25, 35, 45 and the holding pieces 122, 222, 222, 422. Is closed by the foamed resin member 8. Since the resin member 8 also covers the tight materials 15, 25, 35, 45, the heat insulating materials 13, 33, 43, the heat insulating member 60, etc., the tight materials 15, 25, 35, 45, the heat insulating materials 13, 33, 43, and the heat insulating material 8 are also covered. It is also possible to prevent the member 60 from burning out.

図６に示すように、屋内側加熱状態では、屋内面材５２等が熱伸びするため、扉５の上下方向の中間部に対して、扉５の上端部や下端部は屋外側に移動するように反る。このため、扉５の上端部や下端部と、タイト材１５、２５、３５、４５との隙間は、熱反りしていない場合に比べて広くなる。
樹脂部材８が発泡して膨張すると、扉５とドア枠２の見込み面との隙間や、扉５とタイト材１５、２５、３５、４５や保持片部１２２、２２２、３２２、４２２との隙間を、発泡した樹脂部材８が塞ぐ。また、屋内側を加熱するため、タイト材１５、２５、３５、４５が溶融することもあるが、樹脂部材８が発泡して扉５とドア枠２との隙間を塞ぐため、防火性能を確保することができる。
また、樹脂部材８は、断熱材１３、３３、４３、断熱部材６０等も覆うため、断熱材１３、３３、４３、断熱部材６０が焼失することも防止できる。
さらに、鋼板からなる屋外面材５１、屋内面材５２を、リベット６５で直接締結しているため、火災時も屋外面材５１、屋内面材５２の締結状態を維持でき、扉５部分での防火性も確保できる。 As shown in FIG. 6, in the indoor heating state, the indoor surface material 52 and the like heat-extend, so that the upper end and the lower end of the door 5 move to the outdoor side with respect to the intermediate portion in the vertical direction of the door 5. Warp like. Therefore, the gap between the upper end and the lower end of the door 5 and the tight materials 15, 25, 35, and 45 is wider than in the case where the door 5 is not warped by heat.
When the resin member 8 foams and expands, the gap between the door 5 and the prospective surface of the door frame 2 and the gap between the door 5 and the tight materials 15, 25, 35, 45 and the holding pieces 122, 222, 222, 422. Is closed by the foamed resin member 8. Further, since the indoor side is heated, the tight materials 15, 25, 35, and 45 may melt, but the resin member 8 foams to close the gap between the door 5 and the door frame 2, thus ensuring fire prevention performance. can do.
Further, since the resin member 8 also covers the heat insulating materials 13, 33, 43, the heat insulating member 60, and the like, it is possible to prevent the heat insulating materials 13, 33, 43 and the heat insulating member 60 from being burnt down.
Further, since the outdoor surface material 51 and the indoor surface material 52 made of steel plates are directly fastened with the rivet 65, the fastened state of the outdoor face material 51 and the indoor surface material 52 can be maintained even in the event of a fire, and the door 5 portion can be used. Fire resistance can also be ensured.

以上のように、火災時には熱膨張性黒鉛を含有する樹脂部材８が発泡、膨張するため、扉５とドア枠２との隙間を塞ぐことができ、屋外面材５１および屋内面材５２もリベット６５で締結されているので、玄関ドア１において必要な防火性能が確保される。 As described above, since the resin member 8 containing the heat-expandable graphite foams and expands in the event of a fire, the gap between the door 5 and the door frame 2 can be closed, and the outdoor surface material 51 and the indoor surface material 52 are also rivets. Since it is fastened at 65, the necessary fire protection performance is ensured in the entrance door 1.

［第１実施形態による効果］
本実施形態によれば、本発明で得られる効果を奏することができる上、以下の効果も奏することができる。
骨材を不要にできるため、扉５を構成する部品点数も少なくでき、扉５の生産効率を向上できる。その上、扉５を軽量化できるので、扉５を開閉する際に必要な開閉力を低減できる。このため、ユーザーは扉５を容易に開閉でき、ドアクローザーを設けた場合も扉５を確実に閉めることができる。
また、扉５は断熱芯材５３で剛性を確保でき、さらに、屋外面材５１や屋内面材５２の周縁部５１０Ａ〜５１０Ｄ、５２０Ａ〜５２０Ｄでは、屋外面材５１、屋内面材５２を折り曲げているため、周縁部５１０Ａ〜５１０Ｄ、５２０Ａ〜５２０Ｄでの剛性も確保できる。したがって、骨材を設けなくても、扉５として必要な剛性を確保できる。特に、屋外面材５１および屋内面材５２の上下および左右の周縁部５１０Ａ〜５１０Ｄ、５２０Ａ〜５２０Ｄに設けた締結面部である屋外見付け面部５１４Ａ〜５１４Ｄ、屋内見付け面部５２３Ａ〜５２３Ｄをリベット６５で締結しているため、例えば、断熱芯材５３の左右の周縁部５１０Ｃ、５１０Ｄ、５２０Ｃ、５２０Ｄの締結面部のみをリベット６５で締結した場合に比べて扉５の剛性を向上できる。 [Effect of the first embodiment]
According to the present embodiment, the effects obtained by the present invention can be obtained, and the following effects can also be obtained.
Since the aggregate can be eliminated, the number of parts constituting the door 5 can be reduced, and the production efficiency of the door 5 can be improved. Moreover, since the weight of the door 5 can be reduced, the opening / closing force required for opening / closing the door 5 can be reduced. Therefore, the user can easily open and close the door 5, and even when a door closer is provided, the door 5 can be reliably closed.
Further, the door 5 can secure rigidity with the heat insulating core material 53, and further, at the peripheral portions 510A to 510D and 520A to 520D of the outdoor surface material 51 and the indoor surface material 52, the outdoor surface material 51 and the indoor surface material 52 are bent. Therefore, the rigidity at the peripheral portions 510A to 510D and 520A to 520D can be secured. Therefore, the rigidity required for the door 5 can be secured without providing the aggregate. In particular, the outdoor finding surface portions 514A to 514D and the indoor finding surface portions 523A to 523D, which are fastening surface portions provided on the upper and lower peripheral portions 510A to 510D and 520A to 520D of the outdoor surface material 51 and the indoor surface material 52, are fastened with rivets 65. Therefore, for example, the rigidity of the door 5 can be improved as compared with the case where only the fastening surface portions of the left and right peripheral edges 510C, 510D, 520C, and 520D of the heat insulating core material 53 are fastened with the rivets 65.

扉５では、屋外面材５１および屋内面材５２を、リベット６５で直接締結しているので、火災時にも屋外面材５１および屋内面材５２の締結状態を維持できる。このため、扉５およびドア枠２間を樹脂部材８を発泡させて塞ぐことで、遮炎ラインを形成でき、玄関ドア１の防火性能を向上できる。
また、屋内見付け面部５２３Ａ〜５２３Ｃは、屋内面材５２を折り曲げて鋼板が２重に重なっているので、リベット６５の締結時の強度をより向上できる。 At the door 5, since the outdoor surface material 51 and the indoor surface material 52 are directly fastened with the rivet 65, the fastened state of the outdoor face material 51 and the indoor face material 52 can be maintained even in the event of a fire. Therefore, by foaming and closing the resin member 8 between the door 5 and the door frame 2, a flame shielding line can be formed and the fire prevention performance of the entrance door 1 can be improved.
Further, in the indoor finding surface portions 523A to 523C, since the indoor surface material 52 is bent and the steel plates are doubly overlapped, the strength at the time of fastening the rivet 65 can be further improved.

扉５の外周面の屋内側端部に樹脂部材８を設けたので、扉５が熱反りしても、樹脂部材８を建具枠であるドア枠２の見込み面に対向して位置させることができる。したがって、扉５が屋内側だけでなく屋外側に熱反りしても、樹脂部材８の見込み面部８２を、ドア枠２の見込み面に向かって確実に発泡させることができる。このため、ドア枠２と扉５との隙間を、発泡、膨張した見込み面部８２で塞ぐことができ、玄関ドア１の防火性能を向上できる。
また、樹脂部材８は見付け面部８３を備えているので、屋内側見付け面部である保持片部１２２、２２２、３２２、４２２と、扉５との間も、発泡、膨張した見付け面部８３で塞ぐことができる。したがって、玄関ドア１の防火性能をさらに向上できる。 Since the resin member 8 is provided at the indoor end of the outer peripheral surface of the door 5, even if the door 5 is thermally warped, the resin member 8 can be positioned so as to face the prospective surface of the door frame 2 which is a fitting frame. it can. Therefore, even if the door 5 is thermally warped not only on the indoor side but also on the outdoor side, the prospective surface portion 82 of the resin member 8 can be reliably foamed toward the prospective surface of the door frame 2. Therefore, the gap between the door frame 2 and the door 5 can be closed by the foamed and expanded prospective surface portion 82, and the fire prevention performance of the entrance door 1 can be improved.
Further, since the resin member 8 includes the finding surface portion 83, the space between the holding piece portions 122, 222, 222, 422 and the door 5 which are the indoor side finding surface portions is also closed by the foamed and expanded finding surface portion 83. Can be done. Therefore, the fire prevention performance of the entrance door 1 can be further improved.

樹脂部材８は扉５側に設けているので、扉５を開いた場合にドア枠２が露出しても意匠性を低下させることがない。また、扉５を閉めた状態では、樹脂部材８は、保持片部１２２、２２２、３２２、４２２や、タイト材１５、２５、３５、４５で隠されて、樹脂部材８全体が屋内側に露出することはないため、扉５を閉めた状態でも意匠性を維持できる。したがって、意匠性に優れ、防火性能を向上できる玄関ドア１を提供できる。 Since the resin member 8 is provided on the door 5 side, the design is not deteriorated even if the door frame 2 is exposed when the door 5 is opened. Further, when the door 5 is closed, the resin member 8 is hidden by the holding piece portions 122, 222, 222, 422 and the tight materials 15, 25, 35, 45, and the entire resin member 8 is exposed to the indoor side. Since there is no need to do so, the design can be maintained even when the door 5 is closed. Therefore, it is possible to provide the entrance door 1 which is excellent in design and can improve the fire prevention performance.

樹脂部材８は見付け面部８３を備えているので、タイト材１５、２５、３５、４５を、発泡、膨張した見付け面部８３で覆うことができる。このため、不燃性タイト材を用いる必要が無く、扉５を閉めた際に、色合いに制約がある不燃性タイト材が屋内側に露出して意匠性が低下することも防止できる。
さらに、不燃性タイト材に比べて柔らかい一般的なタイト材を用いることができるので、扉５を閉じた場合の反発力も小さくできる。このため、不燃性タイト材を用いたためにドアクローザーで扉５を完全に閉じることもできないといった不具合も防止できる。 Since the resin member 8 includes the finding surface portion 83, the tight materials 15, 25, 35, and 45 can be covered with the foamed and expanded finding surface portion 83. Therefore, it is not necessary to use a nonflammable tight material, and when the door 5 is closed, it is possible to prevent the nonflammable tight material having a limited color from being exposed to the indoor side and deteriorating the design.
Further, since a general tight material that is softer than the nonflammable tight material can be used, the repulsive force when the door 5 is closed can be reduced. Therefore, it is possible to prevent a problem that the door 5 cannot be completely closed by the door closer because the nonflammable tight material is used.

樹脂部材８は、見込み面部８２と、見付け面部８３に加えて、これらの間に配置された連結部８４を設け、連結部８４を断面円弧状に湾曲させて斜め方向に向かって発泡可能に構成したので、見込み面部８２で塞がれる空間と、見付け面部８３で塞がれる空間との間の空間も塞ぐことができる。したがって、発泡、膨張した連結部８４で断熱材１３、３３、４３を覆うこともでき、ドア枠２と扉５との間をより確実に塞ぐことができ、防火性能を向上できる。 In addition to the prospective surface portion 82 and the finding surface portion 83, the resin member 8 is provided with a connecting portion 84 arranged between them, and the connecting portion 84 is curved in a circular arc shape so as to be foamable in an oblique direction. Therefore, the space between the space blocked by the prospective surface portion 82 and the space blocked by the finding surface portion 83 can also be closed. Therefore, the heat insulating materials 13, 33, and 43 can be covered with the foamed and expanded connecting portion 84, and the space between the door frame 2 and the door 5 can be more reliably closed, and the fire prevention performance can be improved.

樹脂部材８は、扉５の屋内面材５２を折曲して形成した凹部５７に配置しているので、樹脂部材８の寸法に合わせて凹部５７を形成することも容易であり、樹脂部材８を屋内面部５２１や屋外見込み面部５１３Ａ〜５１３Ｃ等に対して段差無く配置できる。 Since the resin member 8 is arranged in the recess 57 formed by bending the indoor surface material 52 of the door 5, it is easy to form the recess 57 according to the dimensions of the resin member 8, and the resin member 8 can be easily formed. Can be arranged without a step with respect to the indoor surface portion 521, the outdoor prospective surface portion 513A to 513C, and the like.

［第２実施形態］
次に、本発明の第２実施形態について、図７を参照して説明する。なお、第２実施形態において、第１実施形態と同一または同様の構成については同一符号を付して説明を省略、簡略する。
第２実施形態は、屋外面材５１および屋内面材５２の締結構造と、樹脂部材８の構成が第１実施形態と相違する。
すなわち、図７に示すように、第２実施形態の扉５Ａでは、屋外面材５１は、屋外面部５１１から屋内側に折曲された屋外見込み面部５１３Ｄを備えている。また、屋内面材５２は、屋内面部５２１から屋外側に折曲された外周面部５２２Ｄと、外周面部５２２Ｄの屋外側端部から外周側（ドア枠２側）に折曲された屋内見付け面部５２３Ｄと、屋内見付け面部５２３Ｄから屋外側に延出された屋内見込み面部５２４Ｄとを備えている。
そして、屋外面材５１の屋外見込み面部５１３Ｄの外周側（ドア枠２側）に屋内見込み面部５２４Ｄが配置され、屋外見込み面部５１３Ｄおよび屋内見込み面部５２４Ｄは、これらを見付け方向に貫通するリベット６５Ａによって締結されている。したがって、屋外見込み面部５１３Ｄが屋外面材５１の締結面部であり、屋内見込み面部５２４Ｄが屋内面材５２の締結面部である。なお、リベット６５Ａは、見付け方向に向かって配置されているため、屋外面材５１（屋外見込み面部５１３Ｄ）および屋内面材５２（屋内見込み面部５２４Ｄ）の見込み方向の位置は、それぞれリベット６５Ａを基準に設定される。このため、屋外見込み面部５１３Ｄおよび屋内見込み面部５２４Ｄ間の間隔寸法（スペーサー部８６の厚さ寸法）は、屋外見込み面部５１３Ｄおよび屋内見込み面部５２４Ｄの位置決めに影響しない。 [Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the same or similar configurations as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted or simplified.
In the second embodiment, the fastening structure of the outdoor surface material 51 and the indoor surface material 52 and the configuration of the resin member 8 are different from those of the first embodiment.
That is, as shown in FIG. 7, in the door 5A of the second embodiment, the outdoor surface material 51 includes an outdoor prospective surface portion 513D bent from the outdoor surface portion 511 to the indoor side. Further, the indoor surface material 52 includes an outer peripheral surface portion 522D bent from the indoor surface portion 521 to the outdoor side and an indoor finding surface portion 523D bent from the outdoor side end portion of the outer peripheral surface portion 522D to the outer peripheral side (door frame 2 side). And an indoor prospective surface portion 524D extending from the indoor finding surface portion 523D to the outdoor side.
Then, the indoor prospective surface portion 524D is arranged on the outer peripheral side (door frame 2 side) of the outdoor prospective surface portion 513D of the outdoor surface material 51, and the outdoor prospective surface portion 513D and the indoor prospective surface portion 524D are formed by the rivet 65A penetrating in the finding direction. It has been concluded. Therefore, the outdoor prospective surface portion 513D is the fastening surface portion of the outdoor surface material 51, and the indoor prospective surface portion 524D is the fastening surface portion of the indoor surface material 52. Since the rivet 65A is arranged in the finding direction, the positions of the outdoor surface material 51 (outdoor prospective surface portion 513D) and the indoor surface material 52 (indoor prospective surface portion 524D) in the prospective direction are based on the rivet 65A, respectively. Is set to. Therefore, the spacing dimension (thickness dimension of the spacer portion 86) between the outdoor prospective surface portion 513D and the indoor prospective surface portion 524D does not affect the positioning of the outdoor prospective surface portion 513D and the indoor prospective surface portion 524D.

扉５Ａに設けられる樹脂部材８Ａは、屋外面部８１、見込み面部８２、見付け面部８３、連結部８４を備え、さらに、屋外面部８１から屋外側に延出されたカバー部８５と、屋外見込み面部５１３Ｄおよび屋内見込み面部５２４Ｄ間に配置されるスペーサー部８６とを備えている。
カバー部８５は、ドア枠２の見込み面に対向して設けられて、扉５の屋外面材５１や屋内面材５２の端部を覆うものである。スペーサー部８６は、屋外見込み面部５１３Ｄおよび屋内見込み面部５２４Ｄ間に配置されて、これらが直接接触することを防止している。したがって、スペーサー部８６は、第１実施形態の断熱部材６０と同様に、屋外面材５１および屋内面材５２間に配置された断熱部材を兼ねている。 The resin member 8A provided on the door 5A includes an outdoor surface portion 81, a prospective surface portion 82, a finding surface portion 83, and a connecting portion 84, and further includes a cover portion 85 extending from the outdoor surface portion 81 to the outdoor side and an outdoor prospective surface portion 513D. It also includes a spacer portion 86 arranged between the indoor prospective surface portion 524D.
The cover portion 85 is provided so as to face the prospective surface of the door frame 2 and covers the end portions of the outdoor surface material 51 and the indoor surface material 52 of the door 5. The spacer portion 86 is arranged between the outdoor prospective surface portion 513D and the indoor prospective surface portion 524D to prevent them from coming into direct contact with each other. Therefore, the spacer portion 86 also serves as a heat insulating member arranged between the outdoor surface material 51 and the indoor surface material 52, similarly to the heat insulating member 60 of the first embodiment.

樹脂部材８Ａにおいて、屋外面部８１、見込み面部８２、見付け面部８３、連結部８４は、樹脂部材８と同様に、熱膨張性黒鉛を含有した樹脂で成形されている。また、カバー部８５およびスペーサー部８６は、熱膨張性黒鉛を含有した樹脂で成形してもよいし、熱膨張性黒鉛を含有しない樹脂で成形してもよい。
熱膨張性黒鉛を含有した樹脂でカバー部８５を成形すれば、扉５の外周面とドア枠２の見込み面（側面部４１３）との隙間を塞ぐ領域を増やすことができ、扉５およびドア枠２間で火炎や煙をより確実に遮ることができる。
熱膨張性黒鉛を含有した樹脂でスペーサー部８６を成形すれば、屋外面材５１および屋内面材５２間を確実に塞ぐことができ、断熱芯材５３からガスが発生してもそのガスが屋外面材５１および屋内面材５２間から流出することを防ぐことができる。 In the resin member 8A, the outdoor surface portion 81, the prospective surface portion 82, the finding surface portion 83, and the connecting portion 84 are formed of a resin containing heat-expandable graphite, similarly to the resin member 8. Further, the cover portion 85 and the spacer portion 86 may be molded with a resin containing heat-expandable graphite, or may be molded with a resin containing no heat-expandable graphite.
By molding the cover portion 85 with a resin containing heat-expandable graphite, it is possible to increase the area that closes the gap between the outer peripheral surface of the door 5 and the prospective surface (side surface portion 413) of the door frame 2, and the door 5 and the door. Flames and smoke can be blocked more reliably between the frames 2.
If the spacer portion 86 is formed of a resin containing heat-expandable graphite, the space between the outdoor surface material 51 and the indoor surface material 52 can be reliably closed, and even if gas is generated from the heat insulating core material 53, the gas is outdoors. It is possible to prevent the outflow from between the face material 51 and the indoor face material 52.

扉５Ａの戸先側には、樹脂部材８Ａの屋外側にエッジ材７が取り付けられている。このため、エッジ材７の見込み寸法は、第１実施形態のエッジ材７に比べて短い寸法である。 On the door end side of the door 5A, an edge material 7 is attached to the outdoor side of the resin member 8A. Therefore, the estimated size of the edge material 7 is shorter than that of the edge material 7 of the first embodiment.

［第２実施形態による効果］
第２実施形態によれば、前記第１実施形態と同様の作用効果を奏することができる。
さらに、屋外見込み面部５１３Ｄおよび屋内見込み面部５２４Ｄの見込み方向の位置決めは、リベット６５Ａの軸を基準に設定できるため、屋外見込み面部５１３Ｄおよび屋内見込み面部５２４Ｄの見付け方向の間隔寸法を、スペーサー部８６の厚さ寸法に合わせる必要が無い。このため、スペーサー部８６を圧縮状態で配置する必要が無く、スペーサー部８６の経年劣化も抑制できる。
また、リベット６５Ａは、屋外見込み面部５１３Ｄ、屋内見込み面部５２４Ｄを締結するだけでなく、樹脂部材８Ａの固定にも兼用でき、扉５Ａの生産効率を向上できる。 [Effect of the second embodiment]
According to the second embodiment, the same effects as those of the first embodiment can be obtained.
Further, since the positioning of the outdoor prospective surface portion 513D and the indoor prospective surface portion 524D in the prospective direction can be set with reference to the axis of the rivet 65A, the distance dimension between the outdoor prospective surface portion 513D and the indoor prospective surface portion 524D in the finding direction is set by the spacer portion 86. There is no need to match the thickness dimension. Therefore, it is not necessary to arrange the spacer portion 86 in a compressed state, and the aged deterioration of the spacer portion 86 can be suppressed.
Further, the rivet 65A can be used not only for fastening the outdoor prospective surface portion 513D and the indoor prospective surface portion 524D, but also for fixing the resin member 8A, and can improve the production efficiency of the door 5A.

さらに、樹脂部材８Ａにカバー部８５、スペーサー部８６を設けたので、扉５Ａの外周面を覆うエッジ材や、屋外面材５１および屋内面材５２間に配置される断熱部材を樹脂部材８Ａで兼用することができる。このため、扉５Ａの部品数を少なくできて組立性を向上できる。
さらに、断熱芯材５３と屋外見込み面部５１３Ｄ、屋内見込み面部５２４Ｄとの隙間を小さくできるため、扉５Ａの断熱性能や剛性を向上できる。 Further, since the cover portion 85 and the spacer portion 86 are provided on the resin member 8A, the resin member 8A is used to provide an edge material covering the outer peripheral surface of the door 5A and a heat insulating member arranged between the outdoor surface material 51 and the indoor surface material 52. Can also be used. Therefore, the number of parts of the door 5A can be reduced and the assembling property can be improved.
Further, since the gap between the heat insulating core material 53 and the outdoor prospective surface portion 513D and the indoor prospective surface portion 524D can be reduced, the heat insulating performance and rigidity of the door 5A can be improved.

［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、樹脂部材８としては、図８の扉５Ｂに用いられる樹脂部材８Ｂでもよいし、図９の扉５Ｃに用いられる樹脂部材８Ｃでもよい。扉５Ｂ、５Ｃは、屋外見込み面部５１３Ｄや屋内見込み面部５２４Ｄの寸法が相違し、リベット６５Ａで締結される箇所が異なるものである。すなわち、扉５Ｂでは、締結面部である屋外見込み面部５１３Ｄ、屋内見込み面部５２４Ｄは、扉５Ｂの外周面において、屋外側に近い位置でリベット６５Ａにより締結されている。扉５Ｃでは、締結面部である屋外見込み面部５１３Ｄ、屋内見込み面部５２４Ｄは、扉５Ｃの外周面においてほぼ中間位置でリベット６５Ａにより締結されている。なお、リベット６５Ａは、カバー部８５を貫通して設けられているが、スペーサー部８６はリベット６５Ａに当接する位置までしか延長されていないため、スペーサー部８６を貫通させる必要は無く、その分、樹脂部材８Ｂ、８Ｃの加工も容易にできる。
樹脂部材８Ｂ、８Ｃは、樹脂部材８Ａと同様の構成とされ、屋内見込み面部５２４Ｄの長さ寸法の相違などに応じた形状とされている。
これらの変形例においても、前記第１，２実施形態と同様の作用効果を奏することができる。 [Modification example]
The present invention is not limited to the configuration described in the above embodiments, and modifications within the range in which the object of the present invention can be achieved are included in the present invention.
For example, the resin member 8 may be the resin member 8B used for the door 5B of FIG. 8 or the resin member 8C used for the door 5C of FIG. The doors 5B and 5C have different dimensions of the outdoor prospective surface portion 513D and the indoor prospective surface portion 524D, and are fastened with rivets 65A at different locations. That is, in the door 5B, the outdoor prospective surface portion 513D and the indoor prospective surface portion 524D, which are the fastening surface portions, are fastened by the rivet 65A at a position close to the outdoor side on the outer peripheral surface of the door 5B. In the door 5C, the outdoor prospective surface portion 513D and the indoor prospective surface portion 524D, which are fastening surfaces, are fastened by rivets 65A at substantially intermediate positions on the outer peripheral surface of the door 5C. The rivet 65A is provided so as to penetrate the cover portion 85, but since the spacer portion 86 is extended only to a position where it abuts on the rivet 65A, it is not necessary to penetrate the spacer portion 86, and the spacer portion 86 does not need to penetrate the rivet portion 86. The resin members 8B and 8C can be easily processed.
The resin members 8B and 8C have the same configuration as the resin member 8A, and are shaped according to the difference in length and dimension of the indoor prospective surface portion 524D.
Also in these modified examples, the same action and effect as those of the first and second embodiments can be obtained.

前記各実施形態では、屋内面材５２の端部を折り曲げて凹部５７を形成していたが、凹部５７を設けずに、断熱芯材５３の外周面に沿って折り曲げた外周面部５２２Ａをそのまま屋外側に延長してもよい。この場合も、樹脂部材８、８Ａ〜８Ｃの見付け面部８３が屋内面部５２１と同一面に配置されるように、樹脂部材８、８Ａ〜８Ｃの形状や寸法を設定すればよい。 In each of the above embodiments, the end portion of the indoor surface material 52 is bent to form the recess 57, but the outer peripheral surface portion 522A bent along the outer peripheral surface of the heat insulating core material 53 is used as it is without providing the recess 57. It may be extended to the outside. In this case as well, the shapes and dimensions of the resin members 8, 8A to 8C may be set so that the finding surface portions 83 of the resin members 8, 8A to 8C are arranged on the same surface as the indoor surface portion 521.

前記各実施形態では、屋外面材５１および屋内面材５２の上下および左右の各周縁部５１０Ａ〜５１０Ｄ、５２０Ａ〜５２０Ｄに設けた締結面部をリベット６５、６５Ａで締結していたが、周縁部５１０Ｃ、５１０Ｄ、５２０Ｃ、５２０Ｄに設けた締結面部のみをリベット６５、６５Ａで締結してもよい。すなわち、屋外面材５１および屋内面材５２の少なくとも長手方向に沿った周縁部に設けた締結面部を締結部材で締結すればよい。例えば、前記実施形態のように、縦長の扉５の場合は、屋外面材５１、屋内面材５２の長手方向（上下方向）に沿って設けられる周縁部５１０Ｃ、５１０Ｄ、５２０Ｃ、５２０Ｄに設けた締結面部である屋外見付け面部５１４Ｃ、５１４Ｄと屋内見付け面部５２３Ｃ、５２３Ｄとをリベット６５で締結し、屋外面材５１、屋内面材５２の上下に配置される屋外見付け面部５１４Ａ、５１４Ｂと、屋内見付け面部５２３Ａ、５２３Ｂとは締結しない構成としてもよい。 In each of the above embodiments, the fastening surface portions provided on the upper and lower and left and right peripheral edges 510A to 510D and 520A to 520D of the outdoor surface material 51 and the indoor surface material 52 are fastened with rivets 65 and 65A, but the peripheral edges 510C Only the fastening surface portions provided on the 510D, 520C, and 520D may be fastened with the rivets 65 and 65A. That is, the fastening surface portions provided on the peripheral edges of the outdoor surface material 51 and the indoor surface material 52 at least along the longitudinal direction may be fastened with the fastening member. For example, in the case of the vertically long door 5, as in the above embodiment, the vertically long door 5 is provided on the peripheral edges 510C, 510D, 520C, and 520D provided along the longitudinal direction (vertical direction) of the outdoor surface material 51 and the indoor surface material 52. The outdoor finding surface portions 514C and 514D, which are the fastening surface portions, and the indoor finding surface portions 523C and 523D are fastened with rivets 65, and the outdoor finding surface portions 514A and 514B arranged above and below the outdoor surface material 51 and the indoor surface material 52 and the indoor finding surface portion 514A and 514B. It may be configured not to be fastened to the face portions 523A and 523B.

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。
また、ドア枠としては、アルミ製の屋外部材と、樹脂製の屋内部材とで構成したドア枠でもよい。要するに、建具の断熱性能は、建具を設置する地域等によって設定すればよい。さらに、防火性能が不要な建具の場合には、樹脂部材８を熱膨張性材料が含有されていない一般的な樹脂材料で構成してもよい。 The fitting of the present invention can be used not only as an entrance door but also as various doors such as a self-propelled door. At this time, the present invention can be applied to a fitting provided with two doors, a main door and a child door, and further can be applied to a sliding door type fitting.
Further, the door frame may be a door frame composed of an outdoor member made of aluminum and an indoor member made of resin.
