While making closing property favorable, the opening-and-closing body main body 11 is pulled below with the dead weight, and the bending, wrinkles, etc. which are going to be produced in the opening-and-closing body main body 11 are suppressed.

また、ガイドレール20は、開閉体10の開閉体幅方向の端部を囲む断面略コ字状の部材であり、開閉体開閉方向へわたって長尺状に設けられている。   Further, the guide rail 20 is a member having a substantially U-shaped cross section surrounding the end of the opening / closing body 10 in the opening / closing body width direction, and is provided in a long shape extending in the opening / closing body opening / closing direction.

また、収納部30は、収納ケース32内で巻取軸31を回動させるように構成される。この収納部30は、前記巻取軸31により開閉体10を巻き取ったり巻き戻したりすることで、収納ケース32内へ開閉体10を収納したり、収納ケース32外へ開閉体10を繰り出したりする。   The storage unit 30 is configured to rotate the take-up shaft 31 within the storage case 32.

Any mechanism may be used, such as a mechanism for rotating the winding shaft 31 by its own weight or the weight of the opening / closing body 10 or a combination of these mechanisms. It is preferable to provide a mechanism that is not electrically operated at least when the opening / closing body 10 is drawn out (for example, a mechanism that performs the closing operation using the biasing member, the weight body, or the weight of the opening / closing body 10). .
As another example of the storage unit 30, a configuration in which the winding shaft 31 is exposed without including the storage case 32 may be used.

次に、上述した実施の形態について、その特徴的な作用効果を説明する。
図4は、開閉体10に対する耐火試験の状況を示している。この耐火試験をおおまかに説明すれば、開閉体10を炉内に晒し、その炉内温度を、約1時間30分かけて常温から1000℃近く(より詳細には約978℃)まで上昇させる。そして、前記加熱の後に、開閉体10の表面に対し、水圧約207kPa、放水時間約16秒/m、流量約0.62m/minの放水による衝撃を与える。
そして、前記加熱および放水試験中に、開閉体10に酸化劣化や破損等による開口が生じないこと等が確認される。
Next, characteristic operational effects of the above-described embodiment will be described.
FIG. 4 shows the state of a fire resistance test for the opening / closing body 10. If this fireproof test is roughly explained, the opening / closing body 10 is exposed to a furnace, and the furnace temperature is raised from room temperature to nearly 1000 ° C. (more specifically, about 978 ° C.) over about 1 hour and 30 minutes. And after the said heating, the impact by the water discharge of the water pressure of about 207 kPa, the water discharge time of about 16 seconds / m 2 , and the flow rate of about 0.62 m 3 / min is given to the surface of the opening and closing body 10.
During the heating and water discharge test, it is confirmed that the opening / closing body 10 does not have an opening due to oxidative degradation or breakage.

The wire rope preferably has an outer diameter larger than 0.2 mm and smaller than 0.4 mm, and is configured by combining several (for example, 5 to 9) stainless steel wires. That is, if the outer diameter is 0.2 mm or less, sufficient durability and fire resistance cannot be obtained, and if the outer diameter is 0.4 mm or more, machine sewing becomes extremely difficult.

また、上記実施の形態において、薄肉金属板層11a1と非金属層11a2との間には可能な限り水分が入り込まないことが好ましい。すなわち、水分が浸入した場合には、その水分が加熱されて膨張した場合に、前記層間を隔離や破損等させてしまうおそれがある。
このため、薄肉金属板層11a1と非金属層11a2とを開閉体厚さ方向に接合する作業は、乾燥雰囲気中で行うのが好ましい。
Moreover, in the said embodiment, it is preferable that a water | moisture content does not penetrate as much as possible between the thin metal plate layer 11a1 and the nonmetallic layer 11a2. That is, when moisture enters, when the moisture is heated and expanded, the layers may be separated or damaged.
For this reason, it is preferable to perform the operation | work which joins the thin metal plate layer 11a1 and the nonmetal layer 11a2 in the opening-and-closing body thickness direction in a dry atmosphere.

また、上記実施の形態によれば薄肉金属板層11a1と非金属層11a2との接合や、開閉方向に隣り合う開閉体本体11,11の端部同士の接続のために、ステンレス製のステープラ用つづり針11bやステンレス製のワイヤロープワイヤロープを用いるようにしたが、更に、開閉体構成部材11a同士以外の縫製(例えば開閉体本体11と扉部材12との縫製等)にも、前記ステープラ用つづり針11bやワイヤロープを用いるようにしてもよい。   Further, according to the above embodiment, for joining the thin metal plate layer 11a1 and the non-metal layer 11a2 and connecting the ends of the opening / closing body bodies 11 and 11 adjacent to each other in the opening / closing direction, the stainless steel stapler is used. Although the spelling needle 11b and the stainless steel wire rope wire rope are used, the stapler is also used for sewing other than the opening / closing body constituent members 11a (for example, sewing of the opening / closing body body 11 and the door member 12). A spelling needle 11b or a wire rope may be used.

また、薄肉金属板層11a1と非金属層11a2とを前記ステープラ用つづり針11bやワイヤロープ等によって接合した場合(つまり接着剤による接合構造を用いない場合)には、薄肉金属板層11a1と非金属層11a2との間に浸入した空気により、薄肉金属板層11a1が常温で酸化劣化するのを防ぐために、薄肉金属板層11a1の表面に酸化劣化防止用の金属めっき(例えば亜鉛めっき等)を施すのが好ましい。
逆に、薄肉金属板層11a1と非金属層11a2とを接着剤のみによって接合する場合には、火炎による温度上昇により前記金属めっきが溶融して、薄肉金属板層11a1から非金属層11a2が剥がれ落ちるおそれがあるため、前記金属めっきを施さない態様とするのが好ましい。
When the thin metal plate layer 11a1 and the non-metal layer 11a2 are joined by the stapler spell needle 11b, a wire rope, or the like (that is, when a bonding structure using an adhesive is not used), the thin metal plate layer 11a1 and the non-metal layer 11a1 In order to prevent the thin metal plate layer 11a1 from being oxidatively deteriorated at room temperature by air that has entered between the metal layer 11a2 and the surface of the thin metal plate layer 11a1, metal plating (for example, zinc plating) for preventing oxidative deterioration is applied. It is preferable to apply.
On the contrary, when the thin metal plate layer 11a1 and the nonmetal layer 11a2 are joined only by the adhesive, the metal plating is melted by the temperature rise due to the flame, and the nonmetal layer 11a2 is peeled off from the thin metal plate layer 11a1. Since there is a possibility of falling, it is preferable that the metal plating is not applied.
