Since it is latched by the folding | returning recessed part 115d of the upper frame 11 which is not received directly, or the smoke returning recessed part 143d of the left vertical frame 14, it can prevent that the one-way sliding door 3 falls to the outdoor side.

さらに、片引戸3の垂下片331cや屈曲片334cを補強するステンレス補強材は片引戸3を構成する鋼板32a,32b及びスチール補強材34a、34dに固定されているので、開口部全体がスチール部材と熱膨張耐火材により覆われるので、開口部からの延焼や煙の侵入を防止することができる。   Further, since the stainless steel reinforcing material that reinforces the hanging piece 331c and the bent piece 334c of the sliding door 3 is fixed to the steel plates 32a and 32b and the steel reinforcing materials 34a and 34d constituting the sliding door 3, the entire opening is a steel member. Since it is covered with the thermally expanded refractory material, it is possible to prevent the spread of fire and the intrusion of smoke from the opening.

なお、ステンレス補強材により補強する片は、片引戸3の垂下片331cや屈曲片334cに限るものではなく、防火引戸を設置する場所の状況によって、上枠11の外立上片115aや左縦枠14の屈曲片143bを補強してもよく、また、両者ともに補強しても良い。
また、上枠11の折返し凹部115dや左縦枠14の煙返し凹部143dは、引戸の外方(上方、戸尻方向)に向かって開口されているものではあるが、たとえば戸先側に設ける場合などには、枠体に設ける凹部は引戸の内方に向かって開口されるものでも可能である。
The piece to be reinforced with the stainless steel reinforcing material is not limited to the hanging piece 331c or the bent piece 334c of the single sliding door 3, but depending on the situation of the place where the fireproof sliding door is installed, the vertical upper piece 115a of the upper frame 11 or the left vertical The bent piece 143b of the frame 14 may be reinforced, or both may be reinforced.
Further, the folding recess 115d of the upper frame 11 and the smoke returning recess 143d of the left vertical frame 14 are open toward the outside of the sliding door (upward, door-end direction), but are provided on the door tip side, for example. In some cases, the recess provided in the frame may be opened toward the inside of the sliding door.
