【発明の属する技術分野】
本発明は、住宅などの建物の壁内部に設ける断熱材の施工を簡略化するための金属製断熱内壁枠を、窓枠部の上部及び下部において好適に取り付けることができる取付構造に関する。
【０００２】
【従来の技術】
従来、窓枠部の上部及び下部における壁の内部に断熱材を設けるための施工方法として、図７に示すように、木製の断熱内壁枠１４を窓部軸組み６に固定された窓木台１１又は窓まぐさ１２に固定する方法が知られている。この木製の断熱内壁枠１４は、竪桟１４ａと上弦材（図外）及び下弦材（図外）とを組み合わせて外形が矩形となるように形成された木製の枠体１４ｂと該木製の枠体１４ｂの内部において前記竪桟１４ａ同士をつないだ横桟１４ｃとにより骨組みが構成され、窓の上部及び下部に対応する箇所に断熱材１５が取付けられたものである。また、前記竪桟１４ａは建て込み前又は建て込み後に、図７の２点鎖線で示された窓と干渉する部分が切除される。前記断熱材１５は、グラスウール、ロックウール等の断熱材料で構成されたものであり、その外形は、前記木製の枠体１４ｂと前記横桟１４ｃに囲まれた内側に沿って略矩形となるように形成されている。
【０００３】
前記木製の断熱内壁枠１４を前記窓木台１１又は前記窓まぐさ１２に取付けるに際しては、前記窓木台１１又は前記窓まぐさ１２の屋内側の側部に壁ふかし材１６を釘１７で固定し、該壁ふかし材１６に前記木製の断熱内壁枠１４の前記横桟１４ｃを釘１７で固定し、その後、前記竪桟１４ａ同士も釘１７を用いて固定する。尚、前記木製の断熱内壁枠１４を前記窓木台１１などに固定する施工と共に、前記下弦材（図外）及び前記上弦材（図外）も所定の箇所に釘にて固定する施工も同時に行われる。
【０００４】
図８は上記の施工後の窓枠部の上部及び下部の断面を示したものであり、窓部軸組み６の内側に沿って前記窓木台１１又は前記窓まぐさ１２が設けられており、この窓木台１１又は窓まぐさ１２にサッシ１３が固定され、該サッシ１３の屋内側端部は額縁１８にビス等によって取付られ、前記窓部軸組み６の屋外側には外壁板１９が取付けられており、前記窓木台１１又は前記窓まぐさ１２の室内側の側面に釘１７にて固定された前記壁ふかし材１６に前記木製の断熱内壁枠１４の横桟１４ｃが室内側から釘１７を打込まれて固定されている。
【０００５】
ところで、前記木製の断熱内壁枠１４は、木製であるために、木の反りや前記木製の枠体１４ｂの断面寸法の誤差によって前記木製の枠体１４ｂにおいて段差が生じて、その後の施工に悪い影響を与えたり、見栄えが悪くなる等の問題を有する。
【０００６】
これらの問題を解消するために、本件出願人は、後の「発明の実施の形態」の欄で詳述するように、外形が矩形となるように形成された金属製の枠体と、該枠体で囲まれた内部に設けられた内部断熱材と、前記枠体と略同一の外形を有し、前記枠体の裏側面に設けられた裏面断熱材とを有する金属製断熱内壁枠を用いて壁の内部に断熱材を設ける施工方法を新たに開発した。該金属製断熱内壁枠は、前記窓部軸組みの配置間隔に合致するように形成されており、該金属製断熱内壁枠を前記窓部軸組みに嵌め込んで固定するだけで、断熱材を前記窓部軸組みに取り付けることができるので、容易に壁の内部に設ける断熱材の施工を行うことができる。また、前記枠体が金属製であるために、取付け後の仕上がり精度が向上する。
【０００７】
ところが、上記のような金属製断熱内壁枠を窓の上部及び下部に設ける断熱材の施工を行う場合には、上記従来例のような前記木製の断熱内壁枠１４を前記窓木台１１又は窓まぐさ１２に釘１７で打ち付ける取付方法を採れば、以下に説明する新たな問題が発生する。
【０００８】
前記金属製断熱内壁枠４を構成する部材は金属製の形鋼、或いは、薄板が折曲等されて形成されたものである。図９に示すように、前記金属製断熱内壁枠４の上部及び下部も薄板から形成された部材であって、前記内部断熱材２を保持するために、該内部断熱材２の側に開口部を有するようにコの字断面部材２０が設けられている。ところが、取付のため屋内側より該コの字断面部材２０に釘１７を打ち付けようとすれば、該コの字断面部材２０は前記釘１７の打ち付け方向についてあまり剛性を有しないため、或いは、該コの字断面部材２０が金属の薄板で形成されているがためにこれに釘１７を打込み難く、図９の上に示す前記コの字断面部材２０のように変形させてしてしまうことがある。また、前記金属製断熱内壁枠４は裏側面に柔らかい前記裏面断熱材３を前記窓木台１１又は前記窓まぐさ１２との間に有するため、決められた適切な厚さ方向の位置Ｌを守ることが容易ではなく、該位置Ｌを目視確認しながら前記釘１７を打つ必要があり、煩わしかった。更に、前記金属製断熱内壁枠４を高さ方向について決められた適切な位置に取付けることも必要であり、そのために前記釘１７を打込んで前記金属製断熱内壁枠４を固定する際に前記金属製断熱内壁枠４を手で下から支えて前記決められた適切な位置にくるまで移動させなければならず、作業者に負担がかかるという問題があった。そこで、前記金属製断熱内壁枠４を前記窓部軸組み６に取り付けるための新たな取付構造が必要とされていた。
【０００９】
【発明が解決しようとする課題】
本発明は、上記の課題に鑑みてなされたものであり、本発明の目的は、金属製断熱内壁枠を用いて壁の内部に断熱材を設ける施工方法を実施する場合に、金属製断熱内壁枠を窓の上部及び下部において決められた位置に好適且つ容易に固定することができる取付構造を提供することである。
【００１０】
【課題を解決するための手段】
請求項１記載の発明による窓枠部の金属製断熱内壁枠の取付構造は、外形が矩形となるように形成された金属製の枠体と、該枠体で囲まれた内部に設けられた内部断熱材と、前記枠体と略同一の外形を有し、前記枠体の裏側面に設けられた裏面断熱材とを有する金属製断熱内壁枠の窓枠部の上部及び下部への取付構造であって、垂直部板と、該垂直部板と断面Ｌ字形を形成して設けられた水平部板と、前記垂直部板における前記水平部板と反対側の面の先端部に一端を有しながら前記垂直部板の根元側に延設されると共に前記垂直部板との境界部が水平に設けられた舌状の掛止片と、前記水平部板に穿設された取付用穴とを有する支持金具が、前記垂直部板が窓に対して反対側に向けられ、前記水平部板が屋内側に向けられ、且つ前記掛止片が断面コの字形の窓部軸組みの屋内側のフランジ部に掛合されて前記窓部軸組みの屋内側の側面に固定され、前記金属製断熱内壁枠が前記水平部板の窓に対して反対側の面に固定具を用いて固定された構造である。
【００１１】
【発明の実施の形態】
以下、本発明の実施形態に係る窓枠部の金属製断熱内壁枠の取付構造について図面に基づいて説明する。本発明の実施形態に係る窓枠部の金属製断熱内壁枠の取付構造は、図１、図１のＡ−Ａ断面図である図２及び図３に示すように、外形が矩形となるように形成された金属製の枠体１と、該枠体１で囲まれた内部に設けられた内部断熱材２と、前記枠体１と略同一の外形を有し、前記枠体１の裏側面に設けられた裏面断熱材３とを有する金属製断熱内壁枠４の窓枠部の上部及び下部への取付構造であって、垂直部板５ａと、該垂直部板５ａと断面Ｌ字形を形成して設けられた水平部板５ｂと、前記垂直部板５ａにおける前記水平部板５ｂと反対側の面の先端部に一端を有しながら前記垂直部板５ａの根元側に延設されると共に前記垂直部板５ａとの境界部５ｃが水平に設けられた舌状の掛止片５ｄと、前記水平部板５ｂに穿設された取付用穴５ｅとを有する支持金具５が、前記垂直部板５ａが窓に対して反対側に向けられ、且つ前記水平部板５ｂが屋内側に向けられると共に前記掛止片５ｄが断面コの字形の窓部軸組み６の屋内側のフランジ部６ａに掛合されて前記窓部軸組み６の屋内側の側面に固定され、前記金属製断熱内壁枠４が前記水平部板５ｂの窓に対して反対側の面に固定具７を用いて固定されたことを特徴とするものである。以下、更に詳細に説明する。
【００１２】
前記金属製断熱内壁枠４は、図４及び図４のＢ−Ｂ断面図である図５に示すように、縦枠１ａと横枠１ｂとを組み合わせて外形が矩形となるように形成された金属製の枠体１と、該枠体１で囲まれた内部において前記縦枠１ａ同士又は横枠１ｂ同士をつないで前記枠体１を補強する金属製の桟１ｃとにより骨組みが構成されている。前記枠体１の外形寸法は、前記金属製断熱内壁枠４が取り付けられる窓部軸組み６の配置間隔に合致するように形成される。
【００１３】
前記枠体１で囲まれた内部には、前記桟１ｃと干渉しないように内部断熱材２が設けられている。該内部断熱材２は、袋体内にグラスウール、ロックウール等の断熱材料が収容されて構成されたものであり、その外形は、前記枠体１で囲まれた内部において前記枠体１及び桟１ｃにより囲まれた空間と略同一形状の細長い略矩形となるように形成されている。前記内部断熱材２の取付けは、前記枠体１及び桟１ｃにより囲まれた空間に嵌め込まれるとともに、後述する裏面断熱材３及び防湿シート８により両側から挟まれることにより行われる。
【００１４】
前記枠体１の裏側面、すなわち屋外側面には、裏面断熱材３が設けられる。該裏面断熱材３は、袋体内にグラスウール、ロックウール等の断熱材料が収容されて構成されたものであり、その外形は、前記枠体１の外形と略同一形状の略矩形となるように形成されている。取付けの際は、図６に示すように、前記裏面断熱材３を前記枠体１の裏側面に重ね合わせるように配置し、前記裏面断熱材３の屋内側面にプラスチック板等の当て板９を配置して、その上からステープル１０を打ち込んで前記枠体１又は桟１ｃに固定することにより行われる。なお、前記ステープル１０に代えて釘などを用いることもできる。また、図４又は図５に示すように、前記枠体１の表側面１ｄには、全面に薄い防湿シート８が貼り付けられている。
【００１５】
前記支持金具５は、図３に示すように、垂直部板５ａと該垂直部板５ａと直交する水平部板５ｂとを有するように長方形板材が断面Ｌ字形に折曲されたものである。さらに、前記垂直部板５ａにおける前記水平部板５ｂと反対側の面の先端部に、前記垂直部板５ａとの境界部５ｃとしての一端を残してコの字形に切り込まれ且つ折曲されて前記垂直部板５ａの根元側に延出された舌状の掛止片５ｄが設けられている。該掛止片５ｄの前記境界部５ｃは左右に水平に設けられている。このため、この掛止片５ｄを窓部軸組み６のフランジ部６ａに掛合されれば、前記水平部板５ｂも自ずと水平に設置されることになる。また、該垂直部板５ａと前記掛止片５ｄとの隙間は前記窓部軸組み６の前記フランジ部６ａの厚さと略同じ厚さ或いはそれ以下の隙間を有する。従って、取付け後のがたつき等も少ない。なお、前記水平部板５ｂには前記金属製断熱内壁枠４の下面を固定具７を用いて固定するための取付用穴５ｅが穿設されている。
【００１６】
前記窓部軸組み６は、図１又は図２に示すように、この場合、断面コの字形の溝形鋼であって、窓の両側に縦方向に設けられた軸組み（図外）同士をつないで窓枠部の上部及び下部に水平に設けられたものある。なお、通常、前記窓部軸組み６の窓側には窓木台１１又は窓まぐさ１２が固定され、この窓木台１１等にはサッシ１３が釘等で取付けられる。
【００１７】
前記金属製断熱内壁枠４を窓部軸組み６に取付けるに際しては、図１又は図２に示すように、まず、前記支持金具５を、前記水平部板５ｂを屋内側に向けて、前記垂直部板５ａを窓に対して反対側に向けて、前記垂直部板５ａに設けられた掛止片５ｄを前記窓部軸組み６の窓側のフランジ部６ａへ掛合させて前記窓部軸組み６へ取付ける。このとき、前記支持金具５は、前記掛止片５ｄと前記垂直部板５ａとの間に屋内側の前記フランジ部６ａを挟み込んで掛合する。このため、取付けた後は、がたつき等がなく、しっかりと固定される。また、前記掛止片５ｄの境界部５ｃは前記水平部板５ｂと平行に設けられているため、前記水平部板５ｂは前記窓部軸組み６の窓側の面と平行になる。つまり前記水平部板５ｂは自ずと水平に配置される。
【００１８】
次に、前記金属製断熱内壁枠４を、前記水平部板５ｂの窓に対して反対側の面に設置し、前記水平部板５ｂの縁端と前記断熱内壁枠４の室内側の側面を、図２のＣ部に示すように、揃えて前記金属製断熱内壁枠４を前記水平部板５ｂにビス（固定具）７で固定する。このとき、前記水平部板５ｂは水平に設けられているので前記金属製断熱内壁枠４も水平に設置される。
【００１９】
【発明の効果】
請求項１記載の窓枠部の金属製断熱内壁枠の取付構造は、垂直部板と、該垂直部板と断面Ｌ字形を形成して設けられた水平部板と、前記垂直部板における前記水平部板と反対側の面の先端部に一端を有しながら前記垂直部板の根元側に延設されると共に前記垂直部板との境界部が水平に設けられた舌状の掛止片と、前記水平部板に穿設された取付用穴とを有する支持金具が、前記垂直部板が窓に対して反対側に向けられ、前記水平部板が屋内側に向けられ、且つ前記掛止片が断面コの字形の窓部軸組みの屋内側のフランジ部に掛合されて前記窓部軸組みの屋内側の側面に固定され、前記金属製断熱内壁枠が前記水平部板の窓に対して反対側の面に固定具を用いて固定された構造であるので、前記支持金具は掛止片を窓部軸組みのフランジ部に差込むだけで取付けることができる。また、前記金属製断熱内壁枠の厚さ方向の位置は、前記水平部板の縁端と前記金属製断熱内壁枠の室内側の側面を揃えることによって決まり、上下方向の位置は前記水平部板の位置によって決められているため、位置決めに余計な注意を払う必要がなく、好適に且つ容易に前記金属製断熱内壁枠を取付けることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure capable of suitably mounting a metal heat insulating inner wall frame for simplifying the construction of a heat insulating material provided inside a wall of a building such as a house at an upper part and a lower part of a window frame part.
[0002]
[Prior art]
Conventionally, as a construction method for providing a heat insulating material inside a wall at an upper part and a lower part of a window frame part, as shown in FIG. 7, a window wooden base in which a wooden heat insulating inner wall frame 14 is fixed to a window part frame assembly 6. 11 or a method of fixing to the window lintel 12 is known. This wooden heat insulating inner wall frame 14 is composed of a wooden frame 14b formed by combining an eaves frame 14a with an upper chord material (not shown) and a lower chord material (not shown) so as to have a rectangular outer shape, and the wooden frame. A frame is constituted by the horizontal beam 14c connecting the eaves beam 14a inside the body 14b, and a heat insulating material 15 is attached to portions corresponding to the upper and lower portions of the window. Further, before or after the pier 14a is built, a portion that interferes with the window indicated by a two-dot chain line in FIG. 7 is cut off. The heat insulating material 15 is made of a heat insulating material such as glass wool or rock wool, and the outer shape thereof is substantially rectangular along the inner side surrounded by the wooden frame 14b and the horizontal rail 14c. Is formed.
[0003]
When attaching the wooden heat insulating inner wall frame 14 to the window sill 11 or the window lintel 12, a wall covering material 16 is attached to the indoor side portion of the window sill 11 or the window lintel 12 with a nail 17. Then, the horizontal beam 14 c of the wooden heat insulating inner wall frame 14 is fixed to the wall covering material 16 with a nail 17, and then the ridges 14 a are also fixed to each other using the nail 17. In addition to fixing the wooden heat-insulating inner wall frame 14 to the window base 11 and the like, the lower chord material (not shown) and the upper chord material (not shown) are also fixed to predetermined places with nails. Done.
[0004]
FIG. 8 shows the upper and lower cross-sections of the window frame after the construction, and the window base 11 or the window lintel 12 is provided along the inner side of the window shaft assembly 6. The sash 13 is fixed to the window base 11 or the window lintel 12, and the indoor side end of the sash 13 is attached to the frame 18 with a screw or the like. A horizontal rail 14c of the wooden heat insulating inner wall frame 14 is attached to the indoor side wall 16 of the window wooden base 11 or the window lintel 12 with a nail 17 fixed to the side of the indoor side. A nail 17 is driven in and fixed.
[0005]
By the way, since the said wooden heat insulation inner wall frame 14 is wooden, a level | step difference will arise in the said wooden frame 14b by the curvature of a tree, or the cross-sectional dimension error of the said wooden frame 14b, and it is bad for subsequent construction. It has problems such as impact and poor appearance.
[0006]
In order to solve these problems, the applicant of the present invention, as will be described in detail later in the section of `` Embodiment of the invention '', a metal frame formed to have a rectangular outer shape, A metal heat insulating inner wall frame having an inner heat insulating material provided inside surrounded by a frame body, and a back heat insulating material having substantially the same outer shape as the frame body and provided on a back side surface of the frame body. A new construction method that uses a heat insulating material inside the wall was developed. The metal heat insulating inner wall frame is formed so as to coincide with the arrangement interval of the window portion shaft assembly, and the metal heat insulating inner wall frame is simply fitted and fixed to the window portion shaft assembly. Since it can attach to the said window part shaft assembly, construction of the heat insulating material provided in the inside of a wall can be performed easily. Moreover, since the said frame is metal, the finishing precision after attachment improves.
[0007]
However, when a heat insulating material is provided in which the metal heat insulating inner wall frame as described above is provided at the upper and lower portions of the window, the wooden heat insulating inner wall frame 14 as in the conventional example is replaced with the window base 11 or window. If the mounting method of driving the lintel 12 with the nail 17 is adopted, a new problem described below occurs.
[0008]
The member which comprises the said metal heat insulation inner wall frame 4 is formed by bending a metal shape steel or a thin plate. As shown in FIG. 9, the upper and lower parts of the metal heat insulating inner wall frame 4 are members formed of thin plates, and an opening is formed on the side of the inner heat insulating material 2 in order to hold the inner heat insulating material 2. A U-shaped cross-section member 20 is provided so as to have However, if an attempt is made to drive the nail 17 against the U-shaped cross-section member 20 from the indoor side for mounting, the U-shaped cross-section member 20 is not very rigid in the direction in which the nail 17 is applied. Since the U-shaped cross-section member 20 is formed of a thin metal plate, it is difficult to drive the nail 17 into the U-shaped cross-section member 20 and may be deformed like the U-shaped cross-section member 20 shown in FIG. is there. Moreover, since the said metal heat insulation inner wall frame 4 has the said back surface heat insulating material 3 on the back side surface between the said window wooden stand 11 or the said window lintels 12, the position L of the determined appropriate thickness direction is provided. It was not easy to protect, and it was necessary to hit the nail 17 while visually confirming the position L, which was troublesome. Furthermore, it is also necessary to attach the metal heat insulating inner wall frame 4 to an appropriate position determined in the height direction. Therefore, when the nail 17 is driven and the metal heat insulating inner wall frame 4 is fixed, the metal heat insulating inner wall frame 4 is fixed. There is a problem in that the metal heat insulating inner wall frame 4 must be supported by hand from below and moved until it reaches the determined appropriate position, which places a burden on the operator. Therefore, a new mounting structure for mounting the metal heat insulating inner wall frame 4 to the window frame 6 has been required.
[0009]
