本発明の実施の形態の窓枠の施工方法は、建物の枠状の窓枠下地４の内側に窓枠１を取り付けるための施工方法である。
まず、図５に示すように、窓枠下地４の正面４ａに、枠に沿って枠内にわずかに（例えば、５ｍｍ程度）はみ出すよう室内板５を固定する。室内板５は、例えば、石膏ボード５ａの表面に壁紙５ｂを貼り付けた板から成る。室内板５は、窓枠下地４に石膏ボード５ａを固定した後、その表面に壁紙５ｂを貼り付けて成っても、予め石膏ボード５ａの表面に壁紙５ｂを貼り付けた板から成ってもよい。室内板５は、石膏ボード５ａの表面に塗装した板または表面仕上げ済みパネルから成ってもよい。 The construction method of the window frame according to the embodiment of the present invention is a construction method for attaching the window frame 1 to the inside of the frame-shaped window frame base 4 of the building.
First, as shown in FIG. 5, the interior plate 5 is fixed to the front surface 4a of the window frame base 4 so as to slightly protrude into the frame (for example, about 5 mm) along the frame. The interior board 5 is made of, for example, a board in which wallpaper 5b is attached to the surface of gypsum board 5a. The interior board 5 may be formed by fixing the gypsum board 5a to the window frame base 4 and then attaching the wallpaper 5b to the surface thereof, or may be formed by attaching the wallpaper 5b to the surface of the gypsum board 5a in advance. .. The interior plate 5 may consist of a plate painted on the surface of the gypsum board 5a or a surface-finished panel.

次に、窓枠下地４の枠内面４ｂおよび室内板５の正面側縁部５ｃを窓枠１で覆い、窓枠１を入隅部３に隙間２をあけるよう窓枠下地４に固定する。窓枠１は、窓枠下地４に固定されたとき室内板５の正面側縁部５ｃに対向する位置に、窓枠下地４の正面４ａから枠内にはみ出した室内板５の正面側縁部５ｃを収容する溝部１ｃを有する。入隅部３の隙間２は、一定の幅である必要はない。 Next, the frame inner surface 4b of the window frame base 4 and the front side edge portion 5c of the interior plate 5 are covered with the window frame 1, and the window frame 1 is fixed to the window frame base 4 so as to open a gap 2 in the inside corner portion 3. The window frame 1 is located at a position facing the front side edge portion 5c of the interior plate 5 when fixed to the window frame base 4, and the front side edge portion of the interior plate 5 protruding from the front surface 4a of the window frame base 4 into the frame. It has a groove 1c that accommodates 5c. The gap 2 in the inside corner 3 does not have to have a constant width.

図６に示すように、窓枠用コーナー材１０の挿入部１３を隙間２に挿入する。そして、縁部カバー部１２で窓枠１の正面側縁部１ａを覆って保持し、凸部１４を窓枠１の段差１ｂと係合させる。入隅カバー部１１の両縁部１１ａを、入隅部３を挟む両側面３ａ，３ａに沿って配置する。入隅カバー部１１は、両縁部１１ａが入隅部３を挟む両側面３ａ，３ａに沿って配置されたとき、挿入部１３と反対側の面に入隅部３に沿って谷状に伸びる湾曲部１１ｃを有する。
こうして、本発明の実施の形態の窓枠構造を施工することができる。 As shown in FIG. 6, the insertion portion 13 of the window frame corner material 10 is inserted into the gap 2. Then, the edge cover portion 12 covers and holds the front edge portion 1a of the window frame 1, and the convex portion 14 is engaged with the step 1b of the window frame 1. Both edge portions 11a of the inside corner cover portion 11 are arranged along both side surfaces 3a and 3a sandwiching the inside corner portion 3. When both edge portions 11a are arranged along both side surfaces 3a and 3a sandwiching the inside corner portion 3, the inside corner cover portion 11 is formed in a valley shape along the inside corner portion 3 on the surface opposite to the insertion portion 13. It has an extending curved portion 11c.
In this way, the window frame structure of the embodiment of the present invention can be constructed.

本発明の実施の形態の窓枠の施工方法では、窓枠１を、入隅部３に隙間２をあけて窓枠下地４に固定する。隙間２の幅は、窓枠用コーナー材１０により隙間２が覆われる範囲で調整することができる。このため、窓枠１の寸法精度は厳密でなくともよく、熟練工でなくても容易に施工することができる。また、窓枠下地４に室内板５を固定した後、窓枠下地４に窓枠１を固定するので、室内板５を石膏ボードの表面に壁紙を貼り付けた板、石膏ボードの表面に塗装した板または表面仕上げ済みパネルで構成しておき、窓枠下地４に窓枠１を固定した後、窓枠用コーナー材１０の挿入部１３を入隅部３の隙間２に挿入することにより、工程数を減らして施工を容易にすることができる。
さらに、窓枠用コーナー材１０の縁部カバー部１２が窓枠１の正面側縁部１ａを保持するとともに、凸部１４が窓枠１の段差１ｂと係合しているので、窓枠用コーナー材１０が確実かつ着脱可能に窓枠１の入隅部３に取り付けられる。 In the window frame construction method according to the embodiment of the present invention, the window frame 1 is fixed to the window frame base 4 with a gap 2 in the inside corner portion 3. The width of the gap 2 can be adjusted within a range in which the gap 2 is covered by the window frame corner material 10. Therefore, the dimensional accuracy of the window frame 1 does not have to be strict, and it can be easily constructed even by a non-skilled worker. Further, since the window frame 1 is fixed to the window frame base 4 after the interior plate 5 is fixed to the window frame base 4, the interior plate 5 is painted on the surface of the gypsum board and the surface of the gypsum board. After fixing the window frame 1 to the window frame base 4, the insertion portion 13 of the corner material 10 for the window frame is inserted into the gap 2 of the inside corner portion 3. Construction can be facilitated by reducing the number of steps.
Further, since the edge cover portion 12 of the corner member 10 for the window frame holds the front side edge portion 1a of the window frame 1 and the convex portion 14 is engaged with the step 1b of the window frame 1, it is used for the window frame. The corner member 10 is securely and detachably attached to the inside corner portion 3 of the window frame 1.

窓枠用コーナー材１０は可撓性材料から成るため、入隅部３の隙間２が狭くても挿入部１３を挿入させやすく、また、入隅カバー部１１の両縁部１１ａを、入隅部３を挟む両側面３ａ，３ａに沿わせやすく、縁部カバー部１２で窓枠１の正面側縁部１ａを覆いやすい。入隅カバー部１１の挿入部１３付近に貫通孔を形成すれば、入隅部３の隙間２を利用して隙間２から貫通孔を通して空気を窓側に吹き付け、結露を防止することもできる。 Since the corner material 10 for the window frame is made of a flexible material, it is easy to insert the insertion portion 13 even if the gap 2 of the inside corner portion 3 is narrow, and both edge portions 11a of the inside corner cover portion 11 are inserted into the inside corner. It is easy to follow the side surfaces 3a and 3a sandwiching the portion 3, and it is easy to cover the front side edge portion 1a of the window frame 1 with the edge cover portion 12. If a through hole is formed in the vicinity of the insertion portion 13 of the inside corner cover portion 11, air can be blown from the gap 2 through the through hole to the window side by using the gap 2 of the inside corner portion 3 to prevent dew condensation.
