Description

本考案は、防火性サッシ枠及び断熱・防火窓に関する。   The present invention relates to a fireproof sash frame and a heat insulating / fireproof window.

従来より、アルミニウム合金製のサッシ枠に複層ガラスを嵌めた断熱性を有する窓構造が知られている。アルミニウム系のサッシ枠は、押し出し成形により種々の形状を容易に製造できる利点を有するが、スチールや合成樹脂に比べて熱伝導率が高いため、室外の温度が低い冬場では室内側に結露が生じ易い。
結露を防止するために、アルミニウム合金製のサッシ枠を室内側と室外側とに分割し、分割されたサッシ枠材をウレタン等の合成樹脂による断熱部材で連結して室内外の熱移動を抑制する構成が採られている（特許文献１、２参照）。 2. Description of the Related Art Conventionally, a window structure having heat insulation in which a multi-layer glass is fitted in an aluminum alloy sash frame is known. Aluminum-based sash frames have the advantage that various shapes can be easily manufactured by extrusion molding. However, because they have higher thermal conductivity than steel and synthetic resin, condensation occurs on the indoor side in winter when the outdoor temperature is low. easy.
In order to prevent condensation, the aluminum sash frame is divided into the indoor side and the outdoor side, and the divided sash frame material is connected with a heat insulating member made of synthetic resin such as urethane to suppress heat transfer inside and outside the room. The structure which does is taken (refer patent document 1, 2).

上記のような断熱性を有する窓構造は冷暖房の負荷軽減に寄与しているが、都市部の防火対応の地区（防災地域又は準防災地域）の延焼の恐れのある部位での外壁開口部の窓部には、建築基準法上、防火戸が必要である。
防火戸の認定は、公的機関による防火設備（防火戸）の試験により個別認定されるようになっている。 Although the window structure with heat insulation as described above contributes to reducing the burden of cooling and heating, the opening of the outer wall in the area where there is a risk of fire spread in a fire-resistant district (disaster prevention area or semi-disaster prevention area) in urban areas A fire door is required at the window in accordance with the Building Standard Law.
Fire doors are certified individually by testing fire prevention equipment (fire doors) by public institutions.

上記のようにサッシ枠の室内側と室外側とを合成樹脂の断熱部材で連結した場合、ガラスやサッシ枠に比べてかなり低い温度（例えば２２０℃前後）で合成樹脂が溶けるため、防火戸（防火窓）としては不十分であった。
建築基準法施行令の第１０９条の２には、通常の火災による火熱が加えられた場合に、加熱開始後２０分間加熱面以外の面に火炎を出さないものであることとする「遮炎性能に関する技術的基準」が規定されている。合成樹脂が溶けてサッシ枠の室内外間の連結機能が消失し、サッシ枠の剛性が低下して早期にガラス（網入り複層ガラス等）が脱落するような事態が生じると上記規定を満たし得ない。 As described above, when the indoor side and the outdoor side of the sash frame are connected by a heat insulating member made of synthetic resin, the synthetic resin melts at a considerably lower temperature (for example, around 220 ° C.) compared to glass or the sash frame. It was inadequate as a fireproof window.
Article 109-2 of the Building Standards Law Enforcement Ordinance states that when a heat from a normal fire is applied, no flame will be emitted on surfaces other than the heated surface for 20 minutes after the start of heating. "Technical standards for performance" are defined. If the synthetic resin melts and the connection function between the interior and exterior of the sash frame disappears, the rigidity of the sash frame decreases and the glass (multi-layered glass, etc.) falls off at an early stage, the above regulations can be satisfied. Absent.

サッシ枠を室内側部材と室外側部材とに分割した場合、これらは建物躯体の開口部に個別に固定されるため、地震等の外的要因による加重作用が異なる場合がある。単にセラミックのみで連結する構成とした場合、多孔質で脆性を有するセラミックは振動や曲げ力等でひび割れて長期的には脱落する可能性も否定できない。
そこで、本考案は、グラスウール等の繊維を混入してセラミックの脆性をカバーしつつ、繊維による靭性を付与してセラミックの耐熱性（合成樹脂に対する優位性）を十分に活かすようにした。 In order to achieve the above object, the present invention provides a fireproof sash frame having an indoor member and an outdoor member made of aluminum or an aluminum alloy, and a heat insulating member that connects the indoor member and the outdoor member. The heat insulating member is formed of a ceramic material mixed with fibers.
When the sash frame is divided into the indoor side member and the outdoor side member, these are individually fixed to the opening of the building frame, so that the weighting action due to an external factor such as an earthquake may be different. In the case of a configuration in which the ceramics are simply connected, it is impossible to deny the possibility that the porous and brittle ceramic will crack due to vibration, bending force, etc. and drop out in the long term.
Therefore, in the present invention, fibers such as glass wool are mixed to cover the brittleness of the ceramic, and the toughness by the fibers is imparted to fully utilize the heat resistance of the ceramic (advantage over the synthetic resin).

本考案の防火性サッシ枠において、前記繊維が、グラスウール、炭素繊維、麻、グラスファイバーのうちの少なくとも１つを含む構成としてもよい。
また、本考案の防火性サッシ枠において、前記繊維の長さが０．５ｍｍ〜２．０ｍｍである構成としてもよい。
また、本考案の防火性サッシ枠において、前記繊維が、セルロースナノファイバー又はセルロースナノクリスタルである構成としてもよい。
また、本考案の防火性サッシ枠において、前記セラミック材が、水と化合しスラリー状態を経て硬化するセラミックパウダーを前記繊維と混ぜて固めたものである構成としてもよい。 In the fireproof sash frame of the present invention, the fiber may include at least one of glass wool, carbon fiber, hemp, and glass fiber.
In the fireproof sash frame of the present invention, the length of the fiber may be 0.5 mm to 2.0 mm.
In the fire-resistant sash frame of the present invention, the fiber may be a cellulose nanofiber or a cellulose nanocrystal.
In the fireproof sash frame of the present invention, the ceramic material may be formed by mixing and solidifying ceramic powder that combines with water and hardens through a slurry state.

また、本考案の防火性サッシ枠において、前記室内側部材と前記室外側部材とを予め連結し、前記セラミック材の硬化後に除去されて前記室内側部材と前記室外側部材との間の熱移動を遮断する分離片を一体に有している構成としてもよい。
また、本考案は、防火性サッシ枠と該防火性サッシ枠及び框内に配置され複層防火ガラスを有する障子とを有する断熱・防火窓であって、前記防火性サッシ枠が上記の各特徴を有する防火性サッシ枠であることを特徴とする断熱・防火窓である。
また、本考案の防火窓において、障子が防火性障子框枠を介して防火性サッシ枠内に配置され、前記防火性障子框枠がアルミニウム又はアルミニウム合金製の室内側部材及び室外側部材と、前記室内側部材と前記室外側部材とを連結する断熱部材とを有し、且つ、上記の各特徴を有する防火性サッシ枠と同様の構成を有している構成としてもよい。 Further, in the fire-resistant sash frame of the present invention, the indoor side member and the outdoor side member are connected in advance, and are removed after the ceramic material is hardened to transfer heat between the indoor side member and the outdoor side member. It is good also as a structure which has integrally the separation piece which interrupts | blocks.

本実施形態における断熱部材１０は、繊維を混入したセラミック材で形成されている。セラミック材は、水と化合しスラリー状態を経て硬化するセラミックパウダーを繊維と混ぜて固めたものである。
セラミックパウダーとしては、例えば米国で開発されたＥＡＧＬＥ８（株式会社イーグル・ヴィジョン製）を採用することができる。ＥＡＧＬＥ８は水と化合して短時間で硬化し、硬化収縮が無く、高強度であるため好適である。但し、本考案のセラミックパウダーはこれに限定されない。
繊維としては、グラスウール、炭素繊維、麻、グラスファイバーのうちの少なくとも１つを採用することができる。繊維もこれらに限定されない。 The heat insulating member 10 in the present embodiment is formed of a ceramic material mixed with fibers. The ceramic material is obtained by mixing and solidifying ceramic powder that combines with water and hardens through a slurry state.
As the ceramic powder, for example, EAGLE8 (manufactured by Eagle Vision Co., Ltd.) developed in the United States can be employed. EAGLE8 is suitable because it combines with water and hardens in a short time, has no cure shrinkage, and has high strength. However, the ceramic powder of the present invention is not limited to this.
As the fiber, at least one of glass wool, carbon fiber, hemp, and glass fiber can be employed. The fiber is not limited to these.

バケツ等の不図示の容器内でＥＡＧＬＥ８と水と繊維とを混ぜて混錬し、図４に示すように、スラリー状態のセラミック材３０を開口部２２ａから空間部２２へ充填する。この場合、空間部２２の長手方向の開口端を塞いだ状態で充填する。
セラミック材３０が硬化したら、先が尖った工具３１等でスリット２３に沿って分離片２１を切り離す。
すなわち、分離片２１はセラミック材３０を充填する容器状の空間部２２を形成するために暫定的に設けられるもので、スリット２３の深さはセラミック材３０の充填が可能で且つ硬化後に分離片２１を容易に除去できる程度に設定されている。
上枠４Ａの室内側部材８と室外側部材９には、硬化後のセラミック材３０との一体化を強固にするために、空間部２２内で対向する突縁８ｃ、９ａが形成されている。
スラリー状のセラミック材の符号を３０としているが、上記セラミック材１０、１３、１７と同じものである。 In a container (not shown) such as a bucket, EAGLE 8, water and fibers are mixed and kneaded, and the ceramic material 30 in a slurry state is filled into the space 22 from the opening 22a as shown in FIG. In this case, the filling is performed in a state where the opening end in the longitudinal direction of the space 22 is closed.
When the ceramic material 30 is cured, the separation piece 21 is cut along the slit 23 with a sharp-pointed tool 31 or the like.
That is, the separation piece 21 is provisionally provided to form a container-like space 22 filled with the ceramic material 30, and the depth of the slit 23 can be filled with the ceramic material 30 and is separated after curing. It is set to such an extent that 21 can be easily removed.
The indoor side member 8 and the outdoor side member 9 of the upper frame 4A are provided with protruding edges 8c and 9a that are opposed to each other in the space 22 in order to strengthen the integration with the cured ceramic material 30. .
Although the code | symbol of a slurry-like ceramic material is set to 30, it is the same as the said ceramic materials 10,13,17.

図５は、硬化したセラミック材３０を示している。室内側部材８と室外側部材９の突縁８ｃ、９ａがセラミック材３０内に食い込んだ状態で固まるので、室内側部材８と室外側部材９は硬化したセラミック材３０で一体化される。
セラミックパウダーとしてＥＡＧＬＥ８を使用した場合、硬化収縮が無いので、硬化後のガタツキや反りを抑制することができる。
図５に拡大して示すように、繊維３２がランダムに混ざるので硬化後のセラミック材３０に靭性を付与することができ、多孔質のセラミックの短所である脆性を抑制することができる。 FIG. 5 shows the cured ceramic material 30. Since the protruding edges 8 c and 9 a of the indoor side member 8 and the outdoor side member 9 are hardened in a state where they bite into the ceramic material 30, the indoor side member 8 and the outdoor side member 9 are integrated with the cured ceramic material 30.
When EAGLE8 is used as the ceramic powder, since there is no curing shrinkage, it is possible to suppress rattling and warping after curing.
As shown in FIG. 5 in an enlarged manner, the fibers 32 are randomly mixed, so that toughness can be imparted to the cured ceramic material 30 and brittleness, which is a disadvantage of porous ceramics, can be suppressed.

図６に示すように、地震等の外的要因によって生じ得る防火性サッシ枠４の歪みや捩れによりセラミック材３０に偏加重が作用した場合、セラミックだけの場合にはひびが入って割れが進行し、経時的には脱落する虞もある。割れが大きくなったり脱落すると防火機能が得られない事態も生じ得る。
しかしながら、上記のように繊維３２を混入したセラミック材３０では、ひびが入ってもその進行を食い止めることができ、合成樹脂に対するセラミックの長所である耐熱性を長期に亘って維持することができる。 As shown in FIG. 6, when a partial load is applied to the ceramic material 30 due to distortion or twisting of the fireproof sash frame 4 that may be caused by an external factor such as an earthquake, cracking occurs and cracks occur only in the case of ceramic. However, there is a risk of dropping over time. If the crack grows large or falls off, it may happen that the fire protection function cannot be obtained.
However, in the ceramic material 30 in which the fibers 32 are mixed as described above, the progress can be stopped even if cracks occur, and the heat resistance, which is an advantage of the ceramic with respect to the synthetic resin, can be maintained for a long time.

繊維３２は長すぎると混錬時に絡み合って分散性が悪くなり、硬化後に凝集し易い。
このため、繊維３２の長さは均一な分散性が得られる２．０ｍｍ以下が望ましい。繊維３２の最適な長さは混ぜ合わせて硬化した後のセラミック材の強度試験により材質毎に適宜決定することができる。
セラミックに混入する繊維は実質的に粉状であってもよい。粉状であってもこれらが分散して網目状組織を形成し、靭性が得られる。
この観点から、繊維として、セルロースナノファイバーやセルロースナノクリスタルを採用することもできる。セルロースナノファイバー（ＣＮＦ）は長さが５０００ｎｍ以上で、セルロースナノクリスタル（ＣＮＣ）は長さが１００〜５００ｎｍであるが、実質的に粉状と見做せる。 If the fibers 32 are too long, they will be entangled during kneading, resulting in poor dispersibility and tend to aggregate after curing.
For this reason, the length of the fiber 32 is desirably 2.0 mm or less at which uniform dispersibility can be obtained. The optimum length of the fiber 32 can be appropriately determined for each material by a strength test of the ceramic material after mixing and curing.
The fiber mixed in the ceramic may be substantially powdery. Even if it is powdery, these are dispersed to form a network structure, and toughness can be obtained.
From this viewpoint, cellulose nanofibers or cellulose nanocrystals can also be employed as the fibers. The cellulose nanofiber (CNF) has a length of 5000 nm or more, and the cellulose nanocrystal (CNC) has a length of 100 to 500 nm.
