Description

本発明は、断熱性を向上するために改修した窓に関する。 The present invention relates to a window modified to improve heat insulation.

断熱性を向上するため、既存の窓の室内側に内窓を設置することが従来より行われている。内窓は、既存の額縁の内周側に取付けられるが、既存の額縁の見込み寸法が足りない場合に、既存の額縁の室内側にふかし枠を取付け、額縁を室内側に延長することも知られている（例えば、非特許文献１参照。）。
従来のものは、窓自体の断熱性を向上するだけで、床も含めた断熱改修に対応できるものは無かった。 In order to improve heat insulation, it has been conventionally performed to install an inner window on the indoor side of an existing window. The inner window is attached to the inner periphery of the existing frame, but if the expected size of the existing frame is not enough, a cover frame is attached to the indoor side of the existing frame and the frame is extended to the indoor side. (See, for example, Non-Patent Document 1).
The conventional one only improved the heat insulation of the window itself, and there was no one that could cope with the insulation modification including the floor.

図１，２に示すように、三方の既存額縁６ａ，６ｂ及びふかし枠８ａ，８ｂの内周側面には、樹脂プレート１９が跨って設けてある。樹脂プレート１９の室外側の端部１９ａは、既存の外窓１０の枠のアングル２０に突き当てられ、アングル２０と樹脂プレート１９とが略面一状となっている。樹脂プレート１９の室内側の端部１９ｂは、見切材７ａ，７ｂ（ふかし枠８ａ，８ｂ又はカバー材９ａ，９ｂ）に当接して隠れている。樹脂プレート１９は、裏面にスジ状の折り取り溝２１が見込方向に間隔をおいて複数設けてあり、折り取り溝２１で適宜折り取ることで、既存額縁６ａ，６ｂとふかし枠８ａ，８ｂの見込寸法に合わせて、見込寸法を調節できるようになっている。また樹脂プレート１９は、既存額縁６ａ，６ｂ及びふかし枠８ａ，８ｂの内周側面に両面テープや接着剤で取付けてあり、容易に交換できるようにしてある。 As shown in FIGS. 1 and 2, a resin plate 19 is provided across the inner peripheral side surfaces of the three existing frames 6 a and 6 b and the cover frames 8 a and 8 b. An end 19a on the outdoor side of the resin plate 19 is abutted against an angle 20 of the frame of the existing outer window 10, and the angle 20 and the resin plate 19 are substantially flush with each other. The end 19b on the indoor side of the resin plate 19 is in contact with the parting materials 7a and 7b (the cover frames 8a and 8b or the cover materials 9a and 9b) and is hidden. The resin plate 19 is provided with a plurality of streak-shaped break grooves 21 on the back surface at intervals in the expected direction. By appropriately folding the resin plates 19 with the break grooves 21, the existing frame 6a, 6b and the upper frames 8a, 8b The expected dimension can be adjusted according to the expected dimension. The resin plate 19 is attached to the inner peripheral side surfaces of the existing frames 6a and 6b and the cover frames 8a and 8b with a double-sided tape or an adhesive so that they can be easily replaced.

既設床材２２の上に重ねて設けられる断熱パネル２３は、既存壁２の室内側に設けられる断熱パネル３と同様に真空断熱材を使用したものを用いている。内窓１の下枠４ｂと既設床材２２の間には、図１に示すように、高さ調整材２５が設けてあり、これにより内窓１の下枠４ｂの上端２６を新設床材２４の上面と略同じ高さにしている。高さ調整材２５の厚みは、断熱パネル２３の厚みと略同じになっている。既設の外窓１０の枠のアングル２０と高さ調整材２５の間の既設床材２２の上面には、樹脂プレート１９が設けてある。壁の断熱パネル３の下端部と新設床材２４の室外側端部との間のコーナー部には、図２，３に示すように、巾木３６を取付けている。 The heat insulation panel 23 provided on the existing flooring 22 is used by using a vacuum heat insulating material in the same manner as the heat insulation panel 3 provided on the indoor side of the existing wall 2. As shown in FIG. 1, a height adjusting material 25 is provided between the lower frame 4 b of the inner window 1 and the existing flooring 22, whereby the upper end 26 of the lower frame 4 b of the inner window 1 is newly installed flooring. The height is approximately the same as the upper surface of 24. The thickness of the height adjusting member 25 is substantially the same as the thickness of the heat insulating panel 23. A resin plate 19 is provided on the upper surface of the existing flooring 22 between the angle 20 of the frame of the existing outer window 10 and the height adjusting member 25. As shown in FIGS. 2 and 3, a baseboard 36 is attached to a corner portion between the lower end portion of the heat insulating panel 3 on the wall and the outdoor end portion of the new flooring 24.

内窓１の枠４は、壁の断熱パネル３よりも室内側に出っ張っているため、新設床材２４は図２に示すように、内窓１の下枠４ｂ、竪枠４ｃ及び見切材７ｂを逃がすように、室外側に切り欠き２７を設けている。新設床材２４の室外側端部、内窓１の下枠４ｂと対向する部分には、樹脂製のアングル２８を取付けている。 Since the frame 4 of the inner window 1 protrudes more indoors than the heat insulating panel 3 on the wall, as shown in FIG. 2, the newly installed flooring 24 has a lower frame 4b, a frame 4c, and a parting material 7b as shown in FIG. A notch 27 is provided on the outdoor side so as to escape the air. A resin-made angle 28 is attached to a portion facing the lower end 4b of the inner window 1 on the outdoor end of the new flooring 24.

縦カバー材９ｂの下端部に取付けられる小口キャップ２９は、図４に示すように、縦カバー材９ｂの小口に当接する小口当接部３０と、小口当接部３０より上方に突出し縦カバー材９ｂの中空部に挿入される挿入部３１を有すると共に、縦カバー材９ｂより張り出す板状の隙間塞ぎ部３２を室内側に有している。隙間塞ぎ部３２は、縦カバー材９ｂの見付面カバー部１４より室内側に１５ｍｍ張り出し、見込面カバー部１３より外周側に５ｍｍ張り出している。小口当接部３０は、隙間塞ぎ部３２の上面よりも若干低い位置に設けてある。
小口キャップ２９は、挿入部３１を縦カバー材９ｂの中空部に挿入して縦カバー材９ｂの下端部に取付けられ、縦カバー材９ｂは予め小口キャップ２９を取付けた上でふかし枠８ｂに嵌合取付けされ、取付けると小口キャップ２９が新設床材２４上に載置される。小口キャップ２９は、縦カバー材９ｂの室内側と外周側に張り出す板状の隙間塞ぎ部３２を有しているので、図２に示すように、隙間塞ぎ部３２により新設床材２４の切り欠き２７と縦カバー材９ｂとの隙間が覆われる。また、アングル２８の長手方向の端部が隙間塞ぎ部３２に呑み込まれており、アングル２８の小口が露出しない。小口キャップ２９は、縦カバー材９ｂにネジ止めされていないので、縦カバー材９ｂの加工が不要であり、縦カバー材９ｂが熱で収縮しても不具合が生じない。 As shown in FIG. 4, the fore edge cap 29 attached to the lower end of the vertical cover member 9 b protrudes upward from the fore edge contact portion 30 that contacts the fore edge of the vertical cover member 9 b and the fore edge contact portion 30. While having the insertion part 31 inserted in the hollow part of 9b, it has the plate-shaped clearance gap closing part 32 which protrudes from the vertical cover material 9b on the indoor side. The gap closing portion 32 protrudes 15 mm toward the indoor side from the finding surface cover portion 14 of the vertical cover member 9 b and extends 5 mm toward the outer peripheral side from the expected surface cover portion 13. The fore edge contact portion 30 is provided at a position slightly lower than the upper surface of the gap closing portion 32.
The forehead cap 29 is attached to the lower end portion of the vertical cover material 9b by inserting the insertion portion 31 into the hollow portion of the vertical cover material 9b, and the vertical cover material 9b is fitted into the upper frame 8b with the forehead cap 29 attached in advance. When attached, the small cap 29 is placed on the new flooring 24. Since the fore edge cap 29 has a plate-like gap closing portion 32 that protrudes to the indoor side and the outer peripheral side of the vertical cover material 9b, the new flooring 24 is cut by the gap closing portion 32 as shown in FIG. A gap between the notch 27 and the vertical cover member 9b is covered. Further, the end portion of the angle 28 in the longitudinal direction is squeezed into the gap closing portion 32, and the fore edge of the angle 28 is not exposed. Since the small edge cap 29 is not screwed to the vertical cover material 9b, there is no need to process the vertical cover material 9b, and no trouble occurs even if the vertical cover material 9b contracts due to heat.

次に、本窓の施工手順の一例を述べる。まず、既存額縁６ａ，６ｂの室内側にふかし枠８ａ，８ｂを取付ける。次に、既存額縁６ａ，６ｂ及びふかし枠８ａ，８ｂの内周に樹脂プレート１９を取付け、既設床材２２上に樹脂プレート１９と高さ調整材２５を取付ける。次に、樹脂プレート１９及び高さ調整在２５の上から内窓１の枠４を取付ける。次に、既設床材２２上に断熱パネル２３及び新設床材２４を重ねて設ける。次に、予め小口キャップ１７，２９を上下端部に取付けたカバー材９ａ，９ｂをふかし枠８ａ，８ｂに室内側から嵌合取付けする。その後、既存壁２の室内側に断熱パネル３を取付け、断熱パネル３の小口３ａをカバー材９ａ，９ｂの見込面カバー部１３に当接又は近接させる。 Next, an example of the construction procedure of this window will be described. First, the cover frames 8a and 8b are attached to the indoor side of the existing frames 6a and 6b. Next, the resin plate 19 is attached to the inner peripheries of the existing picture frames 6a and 6b and the cover frames 8a and 8b, and the resin plate 19 and the height adjusting material 25 are attached on the existing flooring 22. Next, the frame 4 of the inner window 1 is attached from above the resin plate 19 and the height adjustment element 25. Next, the heat insulation panel 23 and the new flooring 24 are provided on the existing flooring 22 in an overlapping manner. Next, the cover materials 9a and 9b having the small caps 17 and 29 attached in advance to the upper and lower ends are fitted and attached to the cover frames 8a and 8b from the indoor side. Then, the heat insulation panel 3 is attached to the indoor side of the existing wall 2, and the small edge 3a of the heat insulation panel 3 is brought into contact with or close to the expected surface cover portion 13 of the cover materials 9a and 9b.

以上に述べたように本実施形態の窓は、内窓１を設けることで窓自体の断熱性が向上することに加え、既存壁２の室内側に断熱パネル３を設け、さらに既設床材２２の上に断熱パネル２３を重ねて設けたことで、壁と床の断熱性もあわせて向上させられ、部屋全体の断熱性を向上させることができる。内窓１の下枠４ｂの上端２６が新設床材２４の上面と略同じ高さであるため、内窓１の下枠４ｂが床面より低く、段差ができることがないので、内窓１の下枠４ｂが通行の妨げとなりにくく、バリアフリーに配慮したリフォームが可能である。また、内窓１の下枠４ｂが床面から飛び出さないことで、カバー材９ａ，９ｂによりふかし枠８ａ，８ｂと内窓１の枠４を覆ったこととあわせて、内観意匠がすっきりする。新設床材２４の室外側端部にアングル２８を設けることで、新設床材２４の小口がアングル２８で覆われているので、意匠性が良く、新設床材２４の端部を損傷しない。さらに縦カバー材９ｂの下端部に小口キャップ２９が取付けてあり、小口キャップ２９が新設床材２４上に載置してあることで、縦カバー材９ｂと新設床材２４との間に隙間があかないので、意匠性が良い。また、縦カバー材９ｂの小口が新設床材２４を傷付けることも防止できる。
小口キャップ２９は、縦カバー材９ｂの室内側及び外周側に張り出す隙間塞ぎ部３２を有しているので、新設床材２４に切り欠き２７を荒く大きめに設けたとしても、切り欠き２７と縦カバー材９ｂの隙間を隙間塞ぎ部３２で隠すことができるので、新設床材２２の窓枠近傍の加工を単純化できる。
本窓は、既存壁２、既存額縁６ａ，６ｂ及び既設床材２２をそのまま利用するため、施工が容易である。 As described above, the window of the present embodiment is provided with the inner window 1 to improve the heat insulating property of the window itself. In addition, the heat insulating panel 3 is provided on the indoor side of the existing wall 2 and the existing flooring 22 is provided. By providing the heat insulation panel 23 on top of each other, the heat insulation of the wall and the floor can be improved together, and the heat insulation of the entire room can be improved. Since the upper end 26 of the lower frame 4b of the inner window 1 is substantially the same height as the upper surface of the newly installed flooring 24, the lower frame 4b of the inner window 1 is lower than the floor surface and no step is formed. The lower frame 4b is unlikely to obstruct traffic and can be reformed in consideration of barrier-free. Further, since the lower frame 4b of the inner window 1 does not protrude from the floor surface, the interior design is refreshed together with the cover frames 9a and 9b covering the cover frames 8a and 8b and the frame 4 of the inner window 1. . By providing the angle 28 at the outdoor side end of the new flooring 24, the edge of the new flooring 24 is covered with the angle 28, so that the design is good and the end of the new flooring 24 is not damaged. Further, a small cap 29 is attached to the lower end portion of the vertical cover material 9b, and the small cap 29 is placed on the new floor material 24, so that there is a gap between the vertical cover material 9b and the new floor material 24. There is no design, so the design is good. Further, it is possible to prevent the fore edge of the vertical cover material 9b from damaging the newly installed flooring 24.
Since the fore edge cap 29 has a gap closing portion 32 that protrudes to the indoor side and the outer peripheral side of the vertical cover material 9b, even if the notch 27 is provided on the newly installed flooring 24 to be rough and large, Since the gap of the vertical cover material 9b can be hidden by the gap closing portion 32, the processing in the vicinity of the window frame of the new flooring 22 can be simplified.
Since this window uses the existing wall 2, existing frame 6a, 6b, and existing flooring 22 as they are, construction is easy.

図５は、本発明の窓の第２実施形態を示しており、第１実施形態において既設床材２２と新設床材２４の間の断熱パネル２３を省略したものに相当する。このように断熱パネル２３を省略した場合でも、新設床材２４を既設床材２２の上に重ねて設けることで、床の断熱性を向上することができる。また、新設床材２４として断熱材を一体に備えるものを用いることで、床の断熱性を一層向上することができる。縦カバー材９ｂの下端部には、第１実施形態と同様の小口キャップ２９が取付けられ、小口キャップ２９を新設床材２４の上に載置している。
既設床材２２上には、樹脂プレート１９が既存の外窓１０の枠のアングル２０の室内側の縁から新設床材２４の室外側端部のアングル２８に当接する位置まで設けてあり、内窓１の下枠４ｂを高さ調整材２５を介することなく、樹脂プレート１９を挟んで既設床材２２上に取付けている。内窓１の下枠４ｂの上端２６は、新設床材２４の上面と略同じ高さとなっている。 FIG. 5 shows a second embodiment of the window of the present invention, which corresponds to the first embodiment in which the heat insulating panel 23 between the existing flooring 22 and the new flooring 24 is omitted. Even when the heat insulation panel 23 is omitted in this manner, the heat insulation of the floor can be improved by providing the new floor material 24 so as to overlap the existing floor material 22. Moreover, the heat insulation of a floor can be further improved by using what is equipped with a heat insulating material integrally as the newly installed flooring 24. FIG. A small cap 29 similar to that of the first embodiment is attached to the lower end portion of the vertical cover member 9 b, and the small cap 29 is placed on the new flooring 24.
On the existing flooring 22, the resin plate 19 is provided from the indoor side edge of the angle 20 of the frame of the existing outer window 10 to a position where it abuts on the angle 28 of the outdoor side end of the new flooring 24. The lower frame 4b of the window 1 is attached on the existing flooring 22 with the resin plate 19 interposed therebetween without the height adjusting member 25 being interposed. The upper end 26 of the lower frame 4 b of the inner window 1 is substantially the same height as the upper surface of the new flooring 24.

このように、既設・新設床材２２，２４間に断熱パネル２３を設ける場合は高さ調整材２５を用い、断熱パネル２３を設けない場合には高さ調整材２５を省くことで、何れの場合も内窓１の下枠４ｂの上端２６を新設床材２４の上面と略同じ高さとすることができる。 As described above, when the heat insulation panel 23 is provided between the existing and new flooring materials 22 and 24, the height adjustment material 25 is used, and when the heat insulation panel 23 is not provided, the height adjustment material 25 is omitted. Also in this case, the upper end 26 of the lower frame 4b of the inner window 1 can be made substantially the same height as the upper surface of the new flooring 24.

以上に述べたように、本発明は様々な窓に対して、壁、床、額縁も含めてリフォームが行え、これにより断熱性と意匠性を向上できるものである。本発明の窓は、既設床材２２上に断熱パネル２３及び新設床材２４を設ける場合と、新設床材２４のみを設ける場合の何れにも対応でき、施工主の求めに応じて断熱性のグレードを適宜選択することができる。 As described above, the present invention can reform various windows including walls, floors, and picture frames, thereby improving heat insulation and design. The window of the present invention can cope with both the case where the heat insulation panel 23 and the new floor material 24 are provided on the existing floor material 22 and the case where only the new floor material 24 is provided. A grade can be appropriately selected.

本発明は以上に述べた実施形態に限定されない。外窓１０及び内窓１の窓種は任意であり、引き違い窓に限らず、開き窓やすべり出し窓等であってもよい。内窓１は、樹脂サッシが好ましいが、アルミサッシや木製サッシであってもよい。見切材７ａ，７ｂ（ふかし枠８ａ，８ｂ及びカバー材９ａ，９ｂ）の断面形状や材質は、適宜変更することができる。額縁には、柱や敷居、鴨居など、窓開口部の内周部に設けられる全ての部材が含まれる。既存額縁の内周側を被覆する被覆材は、樹脂プレートの他、木質シートや断熱性を有するフィルム材等でもよい。カバー材９ｂの下端部に取付けられる小口キャップ２９は、カバー材９ｂより張り出す隙間塞ぎ部３２を室内側に有さず、単にカバー材９ｂの小口を覆うだけのものであってもよい。 The present invention is not limited to the embodiments described above. The window type of the outer window 10 and the inner window 1 is arbitrary, and is not limited to the sliding window, and may be an opening window or a sliding window. The inner window 1 is preferably a resin sash, but may be an aluminum sash or a wooden sash. The cross-sectional shape and the material of the parting materials 7a and 7b (the cover frames 8a and 8b and the cover materials 9a and 9b) can be appropriately changed. The frame includes all members provided on the inner periphery of the window opening, such as a pillar, a sill, and a duck. The covering material for covering the inner peripheral side of the existing frame may be a resin sheet, a wood sheet, a heat insulating film material, or the like. The small cap 29 attached to the lower end of the cover material 9b may not cover the gap closing portion 32 protruding from the cover material 9b on the indoor side, but merely cover the small opening of the cover material 9b.
