Description

本発明は、サッシ窓の気密／断熱構造に関する。 The present invention relates to an airtight / insulated structure for a sash window.

従来、住宅などの建物には、引違い窓、上げ下げ窓、ＦＩＸ窓（はめ殺し窓）、外開き窓、内倒し窓、折りたたみ窓、回転窓などのそれぞれ開閉方式や機能が異なる各種サッシ窓が用いられている。 Conventionally, buildings such as houses have various sash windows with different opening and closing methods and functions, such as sliding windows, sash windows, FIX windows (fitting windows), outward-opening windows, inward-turning windows, folding windows, and rotating windows. It is used.

このうち、引違い窓のサッシ窓は、建物の開口部の外周縁に枠体が固設され、開口部を開閉するように、枠体内に２枚の障子をそれぞれ左右方向にスライド移動可能に納めて構成されている。各障子は、アルミ形材や樹脂形材を用いて形成された上框と下框と左右の縦框（一方の縦框は召し合せ框）からなる方形枠状の框と、框の内部に納められたガラスパネルとを備えて形成されている。 Of these, the sash window of the sliding window has a frame body fixed to the outer peripheral edge of the opening of the building, and two shoji screens can be slid left and right inside the frame so as to open and close the opening. It is organized by putting it in. Each shoji is a square frame-shaped stile consisting of an upper stile, a lower stile, and left and right vertical stiles (one vertical stile is a combined stile) formed using aluminum or resin profiles, and inside the stile. It is formed with a housed glass panel.

また、各障子は、障子の上框に断面凹部形状の案内溝が形成され、枠体の上枠に形成された上部レールに案内溝を係合させて配設されている。さらに、下框に戸車が収納され、枠体の下枠に設けられた断面凸状の下部レール上に下框及び戸車を係合させて配設されている。これにより、障子は、枠体の上部レール及び下部レースに案内されて左右方向にスライド移動可能に設けられている。 Further, each shoji is arranged by forming a guide groove having a concave cross section in the upper frame of the shoji and engaging the guide groove with the upper rail formed in the upper frame of the frame body. Further, the door roller is housed in the lower frame, and the lower frame and the door roller are arranged so as to be engaged with each other on the lower rail having a convex cross section provided in the lower frame of the frame body. As a result, the shoji is provided so as to be slidable in the left-right direction by being guided by the upper rail and the lower race of the frame body.

一方、アルミ形材で中空構造の枠体３の下枠３ｂには、図８や図９に示すように、室内側の中空部に樹脂ブリッジ材１０を充填し、断熱性等を確保するようにしている（例えば、特許文献１参照）。また、室内側にフローリングなどの床材との取合部を被覆するアングル材１１が一体に取り付けられる。そして、このアングル材１１には、アルミアングルや樹脂アングルが用いられ、このうち、樹脂アングルを用いると断熱性を高めることができる。 On the other hand, as shown in FIGS. 8 and 9, the lower frame 3b of the frame 3 having a hollow structure made of an aluminum profile is filled with the resin bridge material 10 in the hollow portion on the indoor side to ensure heat insulation and the like. (See, for example, Patent Document 1). Further, the angle member 11 that covers the connecting portion with the floor material such as flooring is integrally attached to the indoor side. An aluminum angle or a resin angle is used for the angle material 11, and among them, the resin angle can improve the heat insulating property.

しかしながら、上記従来のサッシ窓においては、樹脂ブリッジ材１０を下枠３ｂの中空部に充填するため、生産性が悪いという不都合があった。また、外気温、直射日光等の影響によって樹脂ブリッジ材１０に熱収縮が生じるおそれもあり、樹脂ブリッジ材１０に収縮が生じてしまうと、断熱性の低下を招き、アルミ形材の下枠３ｂに樹脂アングル１１を取り付けた周辺部分や、障子２の下框２ｂ周辺に結露が発生しやすくなる。 However, in the above-mentioned conventional sash window, since the resin bridge material 10 is filled in the hollow portion of the lower frame 3b, there is a disadvantage that the productivity is poor. Further, the resin bridge material 10 may be thermally shrunk due to the influence of the outside air temperature, direct sunlight, etc., and if the resin bridge material 10 is shrunk, the heat insulating property is deteriorated, and the lower frame 3b of the aluminum profile is used. Condensation is likely to occur in the peripheral portion where the resin angle 11 is attached to the sash and around the lower stile 2b of the shoji 2.

H is provided, and the inner surface of the side wall portion 4 of the lower frame 3b arranged side by side with the space H interposed therebetween and the surface 11a on the tip end side of the angle member 11 have a flat shape of the airtight / heat insulating main body 7b. The surfaces may be brought into close contact with each other to provide the airtight / heat insulating material 7.

このとき、上記空間Ｈに気密／断熱本体部７ｂの一部を嵌合させたり、空間Ｈを空気層としたり、空間Ｈにアングル材１１と一体または別体の樹脂部を設ける。これにより、この空間Ｈ部分を断熱層として機能させることができる。 At this time, a part of the airtight / heat insulating main body 7b is fitted in the space H, the space H is used as an air layer, and the space H is provided with a resin portion integrated with or separate from the angle member 11. As a result, this space H portion can function as a heat insulating layer.

すなわち、下枠３ｂの側壁部４の上端とアングル材１１の先端部側の下面との間の空間Ｈが、下枠３ｂの側壁部４とアングル材１１とともに気密／断熱材７によって密閉されるため、断熱層として機能する。また、空間Ｈを設け、気密／断熱本体部７ｂが側壁部４の上端部よりも上方に突出することで、図３の気密／断熱構造Ｂよりも、図７の気密／断熱構造Ｂは、気密ラインＲを上方に押し上げることができる。これにより、優れた気密性、断熱性、止水性を発揮させることが可能になる。 That is, the space H between the upper end of the side wall portion 4 of the lower frame 3b and the lower surface on the tip end side of the angle member 11 is sealed by the airtight / heat insulating material 7 together with the side wall portion 4 of the lower frame 3b and the angle member 11. Therefore, it functions as a heat insulating layer. Further, by providing the space H and the airtight / heat insulating main body portion 7b projecting upward from the upper end portion of the side wall portion 4, the airtight / heat insulating structure B of FIG. 7 is more than the airtight / heat insulating structure B of FIG. The airtight line R can be pushed upward. This makes it possible to exhibit excellent airtightness, heat insulation, and water stopping property.

ここで、本実施形態では、サッシ窓Ａがアルミ樹脂複合サッシであり、気密／断熱材７が、下框１ｂと下枠３ｂのアルミ部（金属部材）に接触するようにして、下框１ｂの室内側を向く面と下枠３ｂの側壁部４の室外側を向く面の間に介設（室内側に配設）されている。そして、気密／断熱材７（気密／断熱本体部７ｂ）を上方に突出させつつ下框１ｂと下枠３ｂのアルミ部を繋ぐように設けることにより、見付方向を小さくしつつ断熱層を大きく確保できることが可能になる。 Here, in the present embodiment, the sash window A is an aluminum resin composite sash, and the airtight / heat insulating material 7 is brought into contact with the aluminum portion (metal member) of the lower stile 1b and the lower frame 3b so that the lower sash 1b It is provided (arranged on the indoor side) between the surface of the lower frame 3b facing the indoor side and the surface of the side wall portion 4 of the lower frame 3b facing the outdoor side. Then, by providing the airtight / heat insulating material 7 (airtight / heat insulating main body 7b) so as to connect the aluminum portion of the lower stile 1b and the lower frame 3b while projecting upward, the heat insulating layer is enlarged while reducing the finding direction. It becomes possible to secure.

すなわち、一般に、アルミ樹脂複合サッシは下枠３ｂの側壁部４がアルミでできているため、その上の樹脂アングル材１１の部分を冷気が伝わり、アングル室内側上面に結露が生じやすくなる。これを防止する手法として断熱層を極力大きくすることが考えられるが、断熱層を単に大きくすると見付方向の寸法が大きくなってしまうという不都合を招く。
これに対し、本実施形態の気密／断熱構造Ｂでは、係合基端部７ａを下方に取り付け、気密／断熱本体部７ｂを側壁部４の上端部よりも上方に突出させることで、見付方向を小さくしつつ断熱層を大きく確保できることが可能になる。 That is, in general, since the side wall portion 4 of the lower frame 3b of the aluminum resin composite sash is made of aluminum, cold air is transmitted to the portion of the resin angle material 11 on the side wall portion 4, and dew condensation is likely to occur on the upper surface of the angle chamber side. As a method for preventing this, it is conceivable to make the heat insulating layer as large as possible, but simply making the heat insulating layer large causes the inconvenience that the dimension in the finding direction becomes large.
On the other hand, in the airtight / heat insulating structure B of the present embodiment, the engagement base end portion 7a is attached downward, and the airtight / heat insulating main body portion 7b is projected upward from the upper end portion of the side wall portion 4. It is possible to secure a large heat insulating layer while reducing the direction.

以上、本発明に係るサッシ窓の気密／断熱構造の一実施形態について説明したが、本発明は上記の一実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。 Although one embodiment of the airtight / heat insulating structure of the sash window according to the present invention has been described above, the present invention is not limited to the above one embodiment and can be appropriately modified without departing from the spirit of the present invention. ..
