And a window frame that is formed in a frame shape having a width dimension in the indoor / outdoor direction smaller than the indoor / outdoor direction dimension of the opening frame so as to be accommodated in the opening frame. An opening frame base disposed on the indoor side from the outdoor side end portion of the opening frame in accordance with the amount of indoor side drawing , forming an exterior material space outside the outdoor frame, and attached to the opening frame; and the window frame interior side position than the surface of the outer wall according to the indoor side pull-in amount Is disposed, said the opening frame inner periphery attached window frame to the base, the mounted on the peripheral edge of the opening in succession exterior material covering the outer wall is disposed in the space for the exterior materials, the opening And an opening exterior material having an opening frame side piece that covers the outdoor portion of the frame rather than the window frame of the frame.

また、請求項２に記載の発明は、請求項１に記載の建物の開口部構造において、前記開口枠の室内側端部には、開口中央側に突出した室内側段部が形成され、この室内側段部に前記開口枠下地の室内側端面が突き当てられていることを特徴とする建物の開口部構造である。 According to a second aspect of the present invention, in the opening structure of the building according to the first aspect, an indoor side stepped portion protruding toward the center of the opening is formed at the indoor side end of the opening frame. The opening structure of a building is characterized in that an indoor side end surface of the opening frame base is abutted against an indoor side step.

また、請求項３に記載の発明は、請求項１または請求項２に記載の建物の開口部構造において、前記外壁は、建物ユニットの外壁であることを特徴とする建物の開口部構造である。 The invention described in claim 3 is the building opening structure according to claim 1 or 2, wherein the outer wall is an outer wall of a building unit. .

また、請求項４に記載の発明は、請求項３に記載された建物の開口部構造を有した建物の開口部の製造方法であって、工場において、外壁の開口枠に対し、仕様により異なる外壁厚さや施主の要望などに応じてあらかじめ設定された窓枠室内側引き込み量に応じた位置に開口枠下地を取り付け、次に、この開口枠下地に窓枠を取り付け、その後、建物の建築現場において、必要な最長の長さに形成されている開口用外装材の開口枠側片を、前記窓枠室内側引き込み量に応じた長さに設定し、次に、この開口用外装材を、前記外装材用空間に配置して開口枠の周縁に取り付けることを特徴とする建物の開口部の製造方法である。 The invention according to claim 4 is a method for manufacturing an opening of a building having the opening structure of the building according to claim 3, and differs depending on the specifications with respect to the opening frame of the outer wall in the factory. Attach the base of the opening frame to a position corresponding to the amount of pull-in on the indoor side of the window frame that is set in advance according to the thickness of the outer wall or the client's request , then attach the window frame to this base of the opening frame, and then the building construction site In, the opening frame side piece of the opening exterior material that is formed in the required longest length is set to a length according to the window frame indoor side pull-in amount , then, this opening exterior material, It is the manufacturing method of the opening part of the building characterized by arrange | positioning in the said space for exterior materials, and attaching to the periphery of an opening frame.

請求項１に記載の建物の開口部構造では、外壁の開口部周縁の開口枠に、開口枠下地を取り付け、この開口枠下地に窓枠を取り付ける構造となっている。   In the opening structure of a building according to claim 1, an opening frame base is attached to the opening frame at the periphery of the opening of the outer wall, and a window frame is attached to the opening frame base.

開口枠下地は、開口枠に対して室内外方向に移動可能な外周寸法、かつ、開口枠内に収容可能な幅寸法となっており、外壁の仕様に応じて、開口枠に対する開口枠下地を取り付ける位置を室内外方向に変更でき、あるいは、開口枠下地の室内外方向の幅寸法を変更することでも、開口枠に対する相対位置を変更できる。これにより、開口枠下地に取り付けられる窓枠の位置も、開口枠に対して室内外方向に変更可能となり、外壁表面からの窓の引込寸法を任意に設定できる。   The opening frame base has an outer periphery dimension that can move indoors and outdoors with respect to the opening frame, and a width dimension that can be accommodated in the opening frame. The attachment position can be changed in the indoor / outdoor direction, or the relative position with respect to the opening frame can be changed by changing the width dimension in the indoor / outdoor direction of the opening frame base. As a result, the position of the window frame attached to the base of the opening frame can also be changed in the indoor / outdoor direction with respect to the opening frame, and the drawing size of the window from the outer wall surface can be arbitrarily set.

また、開口枠下地は、開口枠の内周に装着されているため、開口枠の室外側には、開口用外装材の開口枠側片を設置するための空間が確保される。したがって、上記のように窓の引込寸法を任意に設定しても、これに対応して、開口用外装材の開口枠側片の長さを設定することで、窓枠よりも室外側の開口枠を開口枠側片で覆い、高級な邸宅感を演出することができる。   Further, since the opening frame base is mounted on the inner periphery of the opening frame, a space for installing the opening frame side piece of the opening exterior material is secured outside the opening frame. Therefore, even if the window lead-in dimension is arbitrarily set as described above, by setting the length of the opening frame side piece of the opening exterior material correspondingly, the opening outside the window frame is set accordingly. The frame can be covered with an opening frame side piece to produce a high-class mansion feeling.

以上のように、本発明の建物の開口部構造では、設計自由度が向上する。   As described above, in the building opening structure of the present invention, the degree of freedom in design is improved.

請求項２に記載の建物の開口部構造では、開口枠下地を開口枠に取り付ける際には、開口枠下地を室内側段部に突き当てることで位置決めしてから取り付ける。   In the opening structure of a building according to claim 2, when the opening frame base is attached to the opening frame, the opening frame base is attached after being positioned by abutting against the indoor step.

したがって、組み付け時の開口枠下地の位置決めが容易で、作業性に優れる。   Therefore, the positioning of the opening frame base during assembly is easy and the workability is excellent.

請求項４に記載の開口部の製造方法では、建物の建設現場において、外壁の表面からの窓の引込寸法に応じ、開口用外装材の開口枠側片を切断するなどして最適寸法に設定してから、この開口用外装材を開口枠周縁に取り付ける。   In the manufacturing method of the opening part of Claim 4, according to the drawing-in dimension of the window from the surface of an outer wall in the construction site of a building, it sets to the optimal dimension by cutting the opening frame side piece of the exterior material for opening, etc. Then, this exterior packaging material is attached to the periphery of the aperture frame.

したがって、建物の仕様により、外壁表面からの窓の室内側への引込寸法が異なっていても、これに対応して、外装材と窓との間に、開口用外装材を配置させることができる。   Therefore, even if the drawing-in dimension of the window from the outer wall surface to the indoor side differs according to the building specifications, the exterior material for opening can be arranged between the exterior material and the window correspondingly. .

次に、この状態の建物ユニットを、建設現場に運び、結合させて、建物Ｈを建設する。   Next, the building unit in this state is transported to the construction site and coupled to construct the building H.

この際、建設現場では、外壁１の室外ＯＳ側に外装材１３を取り付け、その後、開口部３の室外ＯＳ側に開口用外装材６を取り付ける。この開口用外装材６は、室外片６ａと開口枠側片６ｂとを備えた断面略Ｌ字形状を成すが、各片６ａ，６ｂの長さは、建設現場において、必要に応じて最適の長さに調節する。   At this time, at the construction site, the exterior material 13 is attached to the outdoor OS side of the outer wall 1, and then the opening exterior material 6 is attached to the outdoor OS side of the opening 3. The opening exterior material 6 has a substantially L-shaped cross section including an outdoor piece 6a and an opening frame side piece 6b. The length of each piece 6a, 6b is optimal at the construction site as required. Adjust to length.

そこで、現場において、開口部３の開口枠１８の上枠部分１８ｈおよび縦枠部分１８ｊにおいて、サッシ窓２の室外ＯＳ側に形成されている外装材用空間Ｓの奥行き、ならびに外装材１３からサッシ窓２の外周までの寸法を採寸し、開口用外装材６の各片６ａ，６ｂを、必要な長さに設定した後、開口枠側片６ｂの先端部をシール材８２によりサッシ窓２の窓枠２１に接着し、かつ、室外片６ａの先端部をシール材８１により、外装材１３の端面に接着する。   Therefore, in the field, in the upper frame portion 18h and the vertical frame portion 18j of the opening frame 18 of the opening 3, the depth of the exterior material space S formed on the outdoor OS side of the sash window 2 and the sash from the exterior material 13 are obtained. After measuring the dimension to the outer periphery of the window 2 and setting each piece 6a, 6b of the opening exterior material 6 to a required length, the tip of the opening frame side piece 6b is sealed by the sealing material 82 of the sash window 2. It adheres to the window frame 21, and the tip of the outdoor piece 6 a is adhered to the end surface of the exterior material 13 by the sealing material 81.

例えば、図１，図２に示す状態が、建物Ｈの仕様においてサッシ窓２を最も室内ＲＭ側に引き込んだ状態であれば、これらの図に示す開口枠側片６ｂの長さが最大であり、これらの図に示す状態よりもサッシ窓２の引込寸法が小さくなれば、開口枠側片６ｂを必要に応じて切断する。いずれにしても、開口枠側片６ｂは、建物Ｈの仕様に応じ、必要な最長の長さに形成されていて、必要に応じて切断して使用する。   For example, if the state shown in FIG. 1 and FIG. 2 is a state where the sash window 2 is drawn most into the room RM in the specification of the building H, the length of the opening frame side piece 6b shown in these drawings is the maximum. If the retracted dimension of the sash window 2 is smaller than the state shown in these drawings, the opening frame side piece 6b is cut as necessary. In any case, the opening frame side piece 6b is formed in the longest required length according to the specifications of the building H, and is cut and used as necessary.

また、開口枠１８の下枠部分１８ｋでは、同様に、水切り材７を必要な長さに調節した後、シール材８３により窓枠２１の下端部に接着するとともに、シール材８４により外装材１３の端面に接着する。   Similarly, in the lower frame portion 18 k of the opening frame 18, after the draining material 7 is adjusted to a necessary length, the sealing material 83 is adhered to the lower end portion of the window frame 21, and the exterior material 13 is sealed by the sealing material 84. Adhere to the end face of

このようにして、図３に示す外観を有した外壁１が形成される。この外壁１は、開口部３の周縁に設けられた開口用外装材６がサッシ窓２に向かって延在されるため、外装材１３の板厚が実際よりも厚みを有して見え、高級な邸宅感が得られる。特に、開口用外装材６が、開口枠１８の上枠部分１８ｈと両側の縦枠部分１８ｊ，１８ｊとの３方に設けられているため、縦枠部分１８ｊ，１８ｊのみに設ける場合よりも、より高く邸宅感が得られる。   In this way, the outer wall 1 having the appearance shown in FIG. 3 is formed. In the outer wall 1, since the exterior packaging material 6 provided at the periphery of the opening 3 extends toward the sash window 2, the thickness of the exterior material 13 appears to be thicker than the actual thickness, A mansion feeling is obtained. In particular, since the exterior packaging material 6 is provided in three directions, that is, the upper frame portion 18h of the opening frame 18 and the vertical frame portions 18j and 18j on both sides, than the case of providing only in the vertical frame portions 18j and 18j, Higher house feeling can be obtained.

また、この実施の形態１の開口部構造では、建物Ｈの仕様が異なり、外壁１の厚さ寸法が異なったり、あるいは、施主の好みに対応したりして、外壁１の表面に対するサッシ窓２の位置（室内側への引き込み量）を異ならせる場合、開口枠下地５を固定する位置、あるいは開口枠下地５の室内外方向の幅寸法（図４のＬ）を変えることにより、サッシ窓２の位置を任意に変更させることができる。   In the opening structure of the first embodiment, the specification of the building H is different, the thickness dimension of the outer wall 1 is different, or the sash window 2 with respect to the surface of the outer wall 1 according to the preference of the owner. Sash window 2 is changed by changing the position of fixing the opening frame base 5 or the width dimension (L in FIG. 4) of the opening frame base 5 in the indoor / outdoor direction. The position of can be arbitrarily changed.

すなわち、実施の形態１で示した開口枠下地５を、そのまま実施の形態１で示した外壁１よりも厚みの薄い外壁に適用し、この開口枠下地５にサッシ窓２を取り付けた場合、サッシ窓２の室内ＲＭ側への引き込み量は小さくなる。あるいは、実施の形態１で示した外壁１において、開口枠下地５を、室内側段部１８ａから離して配置してサッシ窓２を取り付けた場合も、サッシ窓２の室内ＲＭ側への引き込み量は小さくなる。   That is, when the opening frame base 5 shown in the first embodiment is applied as it is to the outer wall thinner than the outer wall 1 shown in the first embodiment, and the sash window 2 is attached to the opening frame base 5, the sash The pull-in amount of the window 2 to the room RM side becomes small. Alternatively, in the outer wall 1 shown in the first embodiment, when the sash window 2 is attached by disposing the opening frame base 5 away from the indoor side stepped portion 18a, the amount of the sash window 2 drawn into the indoor RM side Becomes smaller.

一方、実施の形態１で示した開口枠下地５よりも、幅寸法Ｌを小さい開口枠下地（図資料尺）を室内側段部１８ａに突き当てて配置し、これにサッシ窓２を取り付けた場合は、サッシ窓２の室内ＲＭ側への引き込み量はさらに大きなものとなる。あるいは、上述のように、実施の形態１よりも厚みの薄い外壁に適用した場合には、壁厚が薄いにもかかわらず、実施の形態１と同様のサッシ窓２の引き込み量を得ることができる。   On the other hand, an opening frame substrate (drawing material scale) having a width dimension L smaller than that of the opening frame substrate 5 shown in the first embodiment is placed against the indoor side stepped portion 18a, and the sash window 2 is attached thereto. In this case, the pull-in amount of the sash window 2 to the room RM side is further increased. Alternatively, as described above, when applied to an outer wall having a smaller thickness than that of the first embodiment, it is possible to obtain the same amount of pull-in of the sash window 2 as in the first embodiment even though the wall thickness is thin. it can.

なお、このようなサッシ窓２の室内ＲＭ側への引込寸法に応じて、上述のように開口用外装材６の開口枠側片６ｂの長さを調節するが、工場では、サッシ窓２の位置に応じて、額縁１８ｅおよび膳板１８ｇの寸法を調節するものである。   The length of the opening frame side piece 6b of the opening exterior material 6 is adjusted as described above according to the retracted dimension of the sash window 2 to the room RM side. The dimensions of the frame 18e and the saddle plate 18g are adjusted according to the position.

以上説明したように、実施の形態１の建物の開口部構造では、開口枠１８に対して位置を調整可能な開口枠下地５を設け、かつ、この開口枠下地５にサッシ窓２を取り付け、開口枠下地５の室外ＯＳ側に外装材用空間Ｓを有した構造とし、さらに、開口用外装材６の開口枠側片６ｂが、この外装材用空間Ｓを覆ってサッシ窓２まで延在される構造としたため、外壁１の表面からのサッシ窓２の引き込み量を任意に設定できるとともに、この引き込み量に応じて開口枠側片６ｂの長さを調節することができる。   As described above, in the opening structure of the building of the first embodiment, the opening frame base 5 whose position can be adjusted with respect to the opening frame 18 is provided, and the sash window 2 is attached to the opening frame base 5. The exterior frame space 5 has an exterior material space S on the outdoor OS side, and the exterior frame side piece 6b of the exterior exterior material 6 extends to the sash window 2 covering the exterior material space S. Since the structure is such that the amount of the sash window 2 drawn from the surface of the outer wall 1 can be set arbitrarily, the length of the opening frame side piece 6b can be adjusted according to the amount of drawing.

したがって、設計自由度が向上し、高級な邸宅感の演出バリエーションが向上する。   Accordingly, the degree of freedom in design is improved, and the production variation of a luxury mansion feeling is improved.

さらに、実施の形態１では、開口枠下地５を開口枠１８に取り付ける際には、開口枠下地５を室内側段部１８ａに突き当てて位置決めできるようにした。   Further, in the first embodiment, when the opening frame base 5 is attached to the opening frame 18, the opening frame base 5 can be positioned by abutting against the indoor side step portion 18a.

したがって、組み付け時の開口枠下地５の位置決めが容易で、作業性に優れる。   Therefore, the positioning of the opening frame base 5 during assembly is easy and the workability is excellent.

加えて、実施の形態１では、窓枠２１を開口枠下地５に取り付ける際には、窓枠２１の室外側取付フランジ２１ｂを、開口枠下地５の室外側の端面５ｃに当接して位置決めを行った状態で開口枠下地５に固定するようにした。   In addition, in the first embodiment, when the window frame 21 is attached to the opening frame base 5, the outdoor mounting flange 21b of the window frame 21 is brought into contact with the end face 5c on the outdoor side of the opening frame base 5 for positioning. It was made to fix to the opening frame base | substrate 5 in the state performed.

したがって、窓枠２１の位置決め作業が容易となり、作業性に優れる。   Therefore, the positioning operation of the window frame 21 becomes easy and the workability is excellent.

加えて、実施の形態１では、開口用外装材６の開口枠側片６ｂと窓枠２１との間が、シール材８２でシールされている。   In addition, in the first embodiment, the space between the opening frame side piece 6 b of the opening exterior material 6 and the window frame 21 is sealed with the sealing material 82.

したがって、開口用外装材６から窓枠２１に連続するシール構造が得られ、開口用外装材６と窓枠２１との間に、水切りなどの他の部材を介在させるのに比べて、シール性に優れるとともに、組付作業性に優れる。   Therefore, a sealing structure that is continuous from the opening exterior material 6 to the window frame 21 is obtained, and the sealing performance is higher than when other members such as draining are interposed between the opening exterior material 6 and the window frame 21. In addition to being excellent in assembly workability.
