[中桟の作用]
次に、第1実施形態の構成で取り付けられた中桟1の作用について図7を参照して説明する。
火災時に発生する熱で建具Aが加熱されたときには、図7(a)~(c)に示すように、中桟1に長手方向への熱伸びや熱伸びによる熱変形が生じる。
このとき、図7(a)(b)に示すように、火災時に発生する熱で樹脂ピース3が焼失し、樹脂ピース3が配置されていた補強材呑み込み溝d10に空間が生じ、この空間が中桟1の熱伸び吸収代Lとして確保される。
[Effect of middle crosspiece]
Next, the function of the middle crosspiece 1 attached in the configuration of the first embodiment will be explained with reference to FIG. 7.
When the fittings A are heated by the heat generated during a fire, as shown in FIGS. 7(a) to (c), the middle crosspiece 1 undergoes thermal elongation in the longitudinal direction and thermal deformation due to thermal elongation.
At this time, as shown in FIGS. 7(a) and 7(b), the resin piece 3 is burnt down by the heat generated during the fire, and a space is created in the reinforcing material swallowing groove d10 where the resin piece 3 was placed. This is secured as the thermal elongation absorption allowance L of the middle crosspiece 1.

すなわち、中桟1の熱伸びを、補強材呑み込み溝d10に確保された熱伸び吸収代Lの範囲で吸収することができ、この熱伸びによる中桟1の変形量を抑制することができる。
また、中桟1の熱伸びが熱伸び吸収代Lで吸収されるため、熱伸びした中桟1が召し合わせ框d1及び縦框d2に対する押圧力を弱め、召し合わせ框d1及び縦框d2の変形を抑制することができる。
本実施形態の樹脂ピース3は、補強材呑み込み溝d10への中桟1の呑み込み量をわずかなものとしているため、焼失した際には、補強材呑み込み溝d10の深さの略全域に熱伸び吸収代Lを確保できる。
That is, the thermal elongation of the inner crosspiece 1 can be absorbed within the range of the thermal elongation absorption allowance L secured in the reinforcing material swallowing groove d10, and the amount of deformation of the inner crosspiece 1 due to this thermal elongation can be suppressed.
In addition, since the thermal elongation of the middle frame 1 is absorbed by the thermal expansion absorption allowance L, the thermally stretched middle frame 1 weakens the pressing force against the connecting frame d1 and vertical frame d2, and Deformation can be suppressed.
Since the resin piece 3 of this embodiment has a small amount of the inner crosspiece 1 swallowed into the reinforcing material swallowing groove d10, when it is burnt out, thermal expansion spreads over almost the entire depth of the reinforcing material swallowing groove d10. Absorption allowance L can be secured.

中桟1の熱伸びによる変形は、図7(b)(c)に示すように、補強材2でも抑制されている。
すなわち、熱変形の少ない金属でなる補強材2が中桟1を内側から支えることで中桟1の変形を抑制することができる。
The deformation of the inner crosspiece 1 due to thermal elongation is also suppressed by the reinforcing material 2, as shown in FIGS. 7(b) and 7(c).
That is, the reinforcing material 2 made of a metal that is less thermally deformed supports the inner crosspiece 1 from the inside, thereby suppressing the deformation of the inner crosspiece 1.

以上のように、第1実施形態の取付け構成による中桟1は、熱伸びが熱伸び吸収代Lで吸収されることで変形を抑制できると共に、補強材2により中桟1の変形を抑制できる構成で建具Aに取付けられている。
すなわち、第1実施形態の取付け構成による中桟1が取付けられた建具Aは、火災時において中桟1の熱伸びによる召し合わせ框d1及び縦框d2の変形を抑制できると共に、これらの部材の変形によって生じる隙間を小さなものとすることができ、しかも、火災の熱により変形するガラスパネルd5の支持状態を確保することができる。
したがって、火災時の熱による隙間の発生が抑制できると共に、ガラスパネルd5の落下を防止できるため、高い防火性能を有し、火災時における延焼防止機能を高めることができる建具Aとなる。
As described above, in the middle crosspiece 1 according to the mounting configuration of the first embodiment, deformation can be suppressed by absorbing thermal elongation by the thermal elongation absorption allowance L, and deformation of the middle crosspiece 1 can be suppressed by the reinforcing material 2. It is attached to fitting A in the configuration.
That is, the fitting A to which the middle crosspiece 1 according to the installation configuration of the first embodiment is attached can suppress the deformation of the meeting frame d1 and the longitudinal stile d2 due to thermal expansion of the middle crosspiece 1 in the event of a fire, and also prevent the deformation of these members. The gap caused by the deformation can be made small, and the support state of the glass panel d5, which is deformed by the heat of the fire, can be ensured.
Therefore, the generation of gaps due to heat in the event of a fire can be suppressed, and the glass panel d5 can be prevented from falling, resulting in a fitting A that has high fire prevention performance and can enhance the function of preventing the spread of fire in the event of a fire.

図14(a)に示す室外側からの火災発生直後においては、ガラスパネルc5及び外障子Cの召し合わせ框c1に火災の熱による変形が発生する。
このとき、図14(b)に示すように、加熱発泡材e1、e2がない場合には、加熱発泡材e3が発泡し、ガラスパネルc5及び外障子Cの召し合わせ框c1の変形によって室外側で生じる隙間sを塞ごうとする。
しかしながら、図14(c)に示すように、発泡後も火災の熱によるガラスパネルc5及び外障子Cの召し合わせ框c1が変形するため、発泡した加熱発泡材e3とガラスパネルc5及び外障子Cの召し合わせ框c1との間に隙間が生じ、ガラスパネルc5と外障子Cの召し合わせ框c1との間の室外側の隙間sが、ガラスパネルc5と外障子Cの召し合わせ框c1との間の室内側の隙間s1と連通してしまい、炎が隙間sと隙間s1を通過して室外側から室内側に侵入してしまうおそれがあった。

It will communicate with the gap s1.
After this heating foaming material e3 is foamed, the heating foaming materials e1 and e2 are foamed, as shown in FIG. By filling the space, communication between the gap s and the gap s1 can be prevented, thereby preventing flame from entering from the outdoor side to the indoor side.
Therefore, the fire prevention function of fittings A is improved, and the spread of fire can be suppressed.

このとき、図19(a)及び図20(a)に示すように、加熱発泡材e4がない場合には、加熱発泡材e5、e6が発泡し、外障子Cの召し合わせ框c1と内障子Dの召し合わせ框d1との間を塞ぐ。
しかしながら、ガラスパネルc5及び外障子Cの召し合わせ框c1の変形によって、補強材呑み込み溝c10とガラスパネルc5との間に、室外側と室内側とを連通する隙間s2が生じると共に、外障子Cの下框c4の室外側への転びによって、下框c4と召し合わせ框c1との間に隙間s3が生じ、隙間s2と隙間s3とが連通してしまい、炎が連通する隙間s2と隙間s3を通過して室外側から室内側に侵入するおそれがあった。
[Effects of heat foaming materials e4 to e6]
Next, the effects of the heat foaming materials e4 to e6 arranged in this manner will be explained with reference to FIGS. 18 to 20.
As shown in FIGS. 18(a) and (b), immediately after a fire breaks out from the outside, the glass panel c5 and the stile c1 of the outer shoji C may be deformed due to the heat of the fire, and the lower stile c4 of the outer shoji C may be damaged. An outward fall occurs.
At this time, as shown in FIGS. 19(a) and 20(a), if there is no heat-foaming material e4, heat-foaming materials e5 and e6 are foamed, and the combination stile c1 of the outer shoji C and the inner shoji Block the gap between D and the meeting frame d1.
However, due to the deformation of the joining frame c1 of the glass panel c5 and the outer shoji C, a gap s2 is created between the reinforcing material swallowing groove c10 and the glass panel c5, which communicates the outdoor side and the indoor side, and the outer shoji C As the lower stile c4 falls toward the outdoor side, a gap s3 is created between the lower stile c4 and the matching stile c1, and the gap s2 and the gap s3 communicate with each other, and the flame communicates with the gap s2 and the gap s3. There was a risk that it could pass through the room and enter the room from the outside.

これに対して、加熱発泡材e4がある場合には、図19(b)及び図20(b)に示すように、加熱発泡材e4~e6が発泡する。
加熱発泡材e4は、内障子Dの召し合わせ框d1に向かって発泡することで、外障子Cの下框c4の室外側への転びが発生したときに下框c4と召し合わせ框c1との間に生じる隙間s3を塞ぐ。
加熱発泡材e5、e6は、それぞれ外障子Cの召し合わせ框c1と内障子Dの召し合わせ框d1との間に発泡することで、外障子Cの召し合わせ框c1と内障子Dの召し合わせ框d1との間を塞ぐ。
すなわち、加熱発泡材e5、e6で塞ぐことができない隙間s3を加熱発泡材e4が埋めることで、隙間s2と隙間s3との連通を防ぐことができ、これによって、室外側から室内側への炎の侵入を防ぐことができる。
また、加熱発泡材e4は、内障子Dの召し合わせ框(竪部材)d1の室外側の見付面70と向かいあうように配設されているため、発泡した際に内障子Dの召し合わせ框(竪部材)d1が当てになり、下框c4と召し合わせ框c1との間の隙間s3を確実に塞ぐことができる。

The heated foaming material e4 is foamed toward the matching stile d1 of the inner shoji D, so that when the lower stile c4 of the outer shoji C falls toward the outdoor side, the lower stile c4 and the matching stile c1 are foamed. Close up the gap s3 that occurs between them.
The heating and foaming materials e5 and e6 are foamed between the matching stile c1 of the outer shoji C and the matching stile d1 of the inner shoji D, respectively, thereby forming the matching stile c1 of the outer shoji C and the matching stile of the inner shoji D. Close the space between it and the stile d1.
That is, by filling the gap s3 that cannot be filled with the heat foaming materials e5 and e6 with the heat foaming material e4, communication between the gap s2 and the gap s3 can be prevented, thereby preventing the flame from flowing from the outdoor side to the indoor side. can prevent intrusion.
In addition, since the heated foaming material e4 is disposed so as to face the facing surface 70 on the outdoor side of the matching frame (vertical member) d1 of the inner shoji D, when it foams, the heating foaming material e4 will cause the matching frame of the inner shoji D (Vertical member) d1 can be relied upon to reliably close the gap s3 between the lower stile c4 and the matching stile c1.
