している。Inside the door frames 10 and 60 configured as described above, a door 90 is suspended by using a hinge (not shown). The door 90 has such a thickness that it can be accommodated in the door storage portions of the left and right door frames 10 and 60 when the door 90 is closed, as shown by the one-dot chain line in the figure. Close to 50. Further, the outdoor-side corner portion of the door 90 projects to the outer periphery along the door surface to form an eye plate portion 91, and the eye plate portion 91 is the door side decorative cover 4 on the door frame side.
It is located on the step portion 44 formed in the corner portion from the outdoor side of 0.
上記の様な構成を有する本実施例の防火戸においては、
次の様な作用効果が発揮される。In the fire door of the present embodiment having the above configuration,
The following effects are exhibited.
戸枠１０，６０は、耐火性に優れたスチール製であ
り、このスチール製の戸枠と同じくスチール製の扉９０
とが、扉９０の周囲で重なり合っているので、火災時に
仮に戸枠表面の各化粧カバーが損われても、外部から火
炎が侵入する恐れがない。The door frames 10 and 60 are made of steel with excellent fire resistance, and the steel door 90 is the same as the steel door frame.
Since they overlap each other around the door 90, even if each of the decorative covers on the surface of the door frame is damaged in the event of a fire, there is no possibility that flames will enter from the outside.
戸枠の表面は周囲のアルミサッシ等と同じアルミ製の
化粧カバーに覆われており、デザイン的な統一性をとる
ことができる。特に、アルミは、スチールに比べて多様
な加工が可能であることから、デザイン上の制限が少な
くなり、装飾性に優れた種々の形態をとることができ
る。The surface of the door frame is covered with an aluminum decorative cover that is the same as the surrounding aluminum sash, etc., so that the design can be made uniform. In particular, aluminum can be processed in various ways as compared with steel, so that there are less restrictions on design and can take various forms with excellent decorativeness.
スチール製の戸枠の表面が耐蝕性に優れたアルミ製化
粧カバーで被覆されるため、海岸地方の様に塩害による
戸枠の腐蝕が防止され、耐久性の高い防火戸を得ること
ができる。Since the surface of the steel door frame is covered with the aluminum decorative cover having excellent corrosion resistance, the door frame is prevented from being corroded due to salt damage as in the coastal area, and a fire door with high durability can be obtained.
扉の周囲に目板部が一体に形成され、これが化粧カバ
ーに設けた段部に位置しているので、扉と化粧カバーと
の隙間がクランク状に屈曲している。従って、外部から
隙間に工具等を挿入して、扉と枠との間の錠前を外すこ
とができないので、防犯性が向上する。Since the eye plate portion is integrally formed around the door and is located on the stepped portion provided on the decorative cover, the gap between the door and the decorative cover is bent like a crank. Therefore, since the lock between the door and the frame cannot be removed by inserting a tool or the like into the gap from the outside, the crime prevention performance is improved.
また、目板部によって扉と枠との隙間が塞がれるので、
この隙間を大きくしても閉鎖状態は支障がない。従っ
て、地震時に戸枠が多少変型しても、扉と戸枠が間で開
閉不能となることがなく、室内からの避難が容易に行な
え、安全性が高い。Also, since the eye plate part closes the gap between the door and the frame,
Even if this gap is enlarged, there is no problem in the closed state. Therefore, even if the door frame is deformed to some extent in the event of an earthquake, the door and the door frame will not be opened and closed, and the evacuation from the room will be easy and the safety is high.
戸枠の表面に装着する化粧カバーが、すべて室外側か
ら取付けられているので、損傷或いは老朽化した時の化
粧カバーの交換が容易である。Since all the decorative covers to be mounted on the surface of the door frame are attached from the outside of the room, it is easy to replace the decorative cover when it is damaged or aged.
なお、本発明は、上記の実施例に限定されるものではな

る。Note that the present invention is not limited to the above-described embodiment, and for example, the outdoor decorative cover and the door-side decorative cover can be integrated, and the outdoor decorative cover is hollow and the cover plate is It does not have to be provided. Further, the shape of the steel door frame can be appropriately changed depending on the surrounding wall body for fixing the steel door frame, and it should be in the shape of a hat in cross section or hollow like the vertical door frame of the above embodiment. You can Further, if the crime prevention and the case of an earthquake can be solved by other means, it is not necessary to provide the door with the eye plate portion or the decorative cover with the step portion. Of course, even when the door panel is provided on the door, not only the decorative cover but also the door frame itself can be provided with the stepped portion.
