The door pocket side vertical frame 4 is provided with a vertical frame recess (groove) 4a into which the tip of the second shielding plate 13 is inserted when all the doors are closed along the vertical direction.

戸当側縦枠３及び戸袋側縦枠４は、それぞれ筒状である。戸当側縦枠３内の乗場側端部には、第１の耐火材１４ａが部分的に入れられている。戸袋側縦枠４内の乗場側端部には、第２の耐火材１４ｂが部分的に入れられている。第１及び第２の耐火材１４ａ，１４ｂとしては、例えばロックウールが用いられている。また、戸当側縦枠３には、全戸閉時に第１の乗場ドア６の反戸袋側端部が当接する戸当たりゴム１５が固定されている。   Each of the door side vertical frame 3 and the door pocket side vertical frame 4 is cylindrical. A first refractory material 14 a is partially placed at the landing side end in the door-holding side vertical frame 3. A second refractory material 14 b is partially placed at the landing side end in the door pocket side vertical frame 4. As the first and second refractory materials 14a and 14b, for example, rock wool is used. Also, the door stop side vertical frame 3 is fixed with a door stop rubber 15 with which the end portion on the opposite side of the first landing door 6 contacts when all the doors are closed.

戸当側縦枠３は、縦枠本体１６と、ねじ又はリベットにより縦枠本体１６に固定された塞ぎ板１７とを有している。縦枠本体１６の乗場出入口１とは反対側の部分には、上下方向に沿って連続した開口１６ａが設けられている。塞ぎ板１７は、開口１６ａを塞ぐように縦枠本体１６に固定されている。   The door-holding side vertical frame 3 includes a vertical frame main body 16 and a closing plate 17 fixed to the vertical frame main body 16 with screws or rivets. A portion of the vertical frame main body 16 on the side opposite to the hall entrance 1 is provided with an opening 16a continuous along the vertical direction. The closing plate 17 is fixed to the vertical frame body 16 so as to close the opening 16a.

縦枠本体１６は、乗場出入口１に臨む乗場出入口対向部１６ｂと、昇降路内に臨む昇降路対向部の一部である縦枠本体昇降路対向部１６ｃとを有している。縦枠本体昇降路対向部１６ｃの乗場出入口対向部１６ｂとは反対側の端部には、乗場側へ向けて直角に折り曲げられた折曲部１６ｄが設けられている。   The vertical frame main body 16 has a landing entrance facing portion 16b facing the landing entrance 1 and a vertical frame main body hoistway facing portion 16c which is a part of the hoistway facing portion facing the hoistway. A bent portion 16d bent at a right angle toward the landing side is provided at the end of the vertical frame main body hoistway facing portion 16c opposite to the landing entrance facing portion 16b.

縦枠本体昇降路対向部１６ｃには、縦枠断熱材１８が接合されている。縦枠断熱材１８は、戸当側縦枠３の上下方向の全体に渡って連続して設けられている。また、縦枠断熱材１８は、取付金具１９により縦枠本体昇降路対向部１６ｃとの間に挟持されている。   A vertical frame heat insulating material 18 is joined to the vertical frame main body hoistway facing portion 16c. The vertical frame heat insulating material 18 is continuously provided over the entire vertical direction of the door side vertical frame 3. Further, the vertical frame heat insulating material 18 is sandwiched between the vertical frame main body hoistway facing portion 16 c by the mounting bracket 19.

縦枠断熱材１８としては、例えばシリカ系断熱材、石膏ボード、珪酸カルシウムボード、又はロックウールボード等が使用されている。また、縦枠本体昇降路対向部１６ｃは、ドアパネル８，１１よりも熱源から離れているため、縦枠断熱材１８の断熱性は、ドア断熱材９，１２の断熱性よりも低くすることができる。   As the vertical frame heat insulating material 18, for example, a silica heat insulating material, a gypsum board, a calcium silicate board, or a rock wool board is used. Moreover, since the vertical frame main body hoistway facing part 16c is farther from the heat source than the door panels 8 and 11, the heat insulating property of the vertical frame heat insulating material 18 may be lower than the heat insulating properties of the door heat insulating materials 9 and 12. it can.

取付金具１９は、乗場出入口対向部１６ｂから遠い側の第１の端部１９ａと、乗場出入口対向部１６ｂに近い側の第２の端部１９ｂとを有している。第１の端部１９ａは、折曲部１６ｄに接合され固定されている。また、第１の端部１９ａは、ねじ又はリベットにより折曲部１６ｄに固定されている。第２の端部１９ｂと縦枠本体昇降路対向部１６ｃとの間には、例えば５ｍｍ程度の隙間が確保されている。   The mounting bracket 19 has a first end 19a far from the landing entrance facing portion 16b and a second end 19b near the landing entrance facing portion 16b. The first end 19a is joined and fixed to the bent portion 16d. The first end portion 19a is fixed to the bent portion 16d with a screw or a rivet. For example, a gap of about 5 mm is secured between the second end 19b and the vertical frame main body hoistway facing portion 16c.

このような乗場出入口装置では、乗場側で発生した火災により乗場出入口対向部１６ｂが加熱されると、その熱が縦枠本体昇降路対向部１６ｃに伝導する。しかし、縦枠本体昇降路対向部１６ｃには縦枠断熱材１８が取り付けられているので、縦枠本体昇降路対向部１６ｃの熱により昇降路内の機器が加熱され発火するのを防止することができる。即ち、乗場の熱が昇降路内に伝わるのを、より確実に防止することができる。   In such a landing / entrance device, when the landing / entrance facing portion 16b is heated by a fire generated on the landing side, the heat is conducted to the vertical frame main body hoistway facing portion 16c. However, since the vertical frame heat insulating material 18 is attached to the vertical frame main body hoistway facing portion 16c, it prevents the equipment in the hoistway from being heated and ignited by the heat of the vertical frame main body hoistway facing portion 16c. Can do. That is, it is possible to more reliably prevent the heat of the landing from being transmitted into the hoistway.

また、縦枠本体１６内の温度分布は、熱源に近い乗場出入口対向部１６ｂが最も高くなり、乗場出入口対向部１６ｂから離れるに従って低くなる。そして、取付金具１９は、乗場出入口対向部１６ｂから遠い第１の端部１９ａで折曲部１６ｄに固定され、第２の端部１９ｂと縦枠本体昇降路対向部１６ｃとの間に隙間が設けられているので、取付金具１９が高温になるのも防止することができる。   Further, the temperature distribution in the vertical frame body 16 is highest at the landing entrance facing portion 16b close to the heat source, and decreases as the distance from the landing entrance facing portion 16b increases. The mounting bracket 19 is fixed to the bent portion 16d at the first end 19a far from the landing entrance facing portion 16b, and there is a gap between the second end 19b and the vertical frame main body hoistway facing portion 16c. Since it is provided, it is possible to prevent the mounting bracket 19 from becoming high temperature.

実施の形態２．
次に、図４はこの発明の実施の形態２によるエレベータの乗場出入口装置の断面図、図５は図４の要部を拡大して示す断面図、図６は図５の戸当側縦枠を昇降路側から見た背面図である。また、図４は図１のＩＩ−ＩＩ線に沿う断面に相当する。図において、乗場三方枠２は、戸当側縦枠２１、戸袋側縦枠４及び上枠５を有している。Embodiment 2. FIG.
Next, FIG. 4 is a sectional view of an elevator landing doorway apparatus according to Embodiment 2 of the present invention, FIG. 5 is a sectional view showing an enlarged main part of FIG. 4, and FIG. It is the rear view which looked at from the hoistway side. 4 corresponds to a cross section taken along line II-II in FIG. In the figure, the landing three-way frame 2 has a door side vertical frame 21, a door pocket side vertical frame 4 and an upper frame 5.

戸当側縦枠２１は、筒状であり、縦枠本体２２と、ねじ又はリベットにより縦枠本体２２に固定された塞ぎ板２３とを有している。縦枠本体２２の乗場出入口１とは反対側の部分には、上下方向に沿って連続した開口２２ａが設けられている。塞ぎ板２３は、開口２２ａを塞ぐように縦枠本体２２に固定されている。   The door side vertical frame 21 has a cylindrical shape and includes a vertical frame main body 22 and a closing plate 23 fixed to the vertical frame main body 22 with screws or rivets. A portion of the vertical frame main body 22 on the side opposite to the landing entrance 1 is provided with an opening 22a that is continuous in the vertical direction. The closing plate 23 is fixed to the vertical frame body 22 so as to close the opening 22a.

縦枠本体２２は、乗場出入口１に臨む乗場出入口対向部２２ｂと、昇降路内に臨む昇降路対向部の一部である縦枠本体昇降路対向部２２ｃとを有している。縦枠本体昇降路対向部２２ｃは、その下端部を乗場敷居（図示せず）に強固に固定するとともに縦枠本体２２自体の剛性を確保するために、実施の形態１の縦枠本体昇降路対向部１６ｃと同様の断面を有している。縦枠本体昇降路対向部２２ｃの乗場出入口対向部２２ｂとは反対側の端部には、乗場側へ向けて直角に折り曲げられた折曲部２２ｄが設けられている。縦枠本体昇降路対向部２２ｃには、開口（切欠）２２ｅが設けられている。開口２２ｅは、上下方向に沿って連続して設けられている。   The vertical frame main body 22 has a landing entrance facing portion 22b facing the landing doorway 1 and a vertical frame main body hoistway facing portion 22c which is a part of the hoistway facing portion facing the hoistway. The vertical frame main body hoistway facing portion 22c is firmly fixed to a landing sill (not shown), and the vertical frame main body hoistway of Embodiment 1 is secured in order to secure the rigidity of the vertical frame main body 22 itself. It has the same cross section as the facing portion 16c. A bent portion 22d bent at a right angle toward the landing side is provided at the end of the vertical frame main body hoistway facing portion 22c opposite to the landing entrance facing portion 22b. The vertical frame main body hoistway facing portion 22c is provided with an opening (notch) 22e. The opening 22e is provided continuously along the vertical direction.

縦枠本体昇降路対向部２２ｃの裏面には、縦枠断熱材２４が設けられている。縦枠断熱材２４は、開口２２ｅを通して昇降路内に露出されている。また、縦枠断熱材２４は、断面コ字形の取付金具２５により開口２２ｅの縁部との間に挟持されている。取付金具２５は、折曲部２２ｄと塞ぎ板２３とに接合され固定されている。他の構成は、実施の形態１と同様である。   A vertical frame heat insulating material 24 is provided on the back surface of the vertical frame main body hoistway facing portion 22c. The vertical frame heat insulating material 24 is exposed in the hoistway through the opening 22e. In addition, the vertical frame heat insulating material 24 is sandwiched between the edge of the opening 22e by a mounting bracket 25 having a U-shaped cross section. The mounting bracket 25 is joined and fixed to the bent portion 22d and the closing plate 23. Other configurations are the same as those in the first embodiment.

このような乗場出入口装置では、乗場側で発生した火災により乗場出入口対向部２２ｂが加熱されると、その熱が縦枠本体昇降路対向部２２ｃに伝導する。しかし、縦枠本体昇降路対向部２２ｃには大きな開口２２ｅが設けられているため、熱伝導する部分が少ない。また、開口２２ｅは縦枠断熱材２４により遮蔽されている。従って、縦枠本体昇降路対向部２２ｃの熱により昇降路内の機器が加熱され発火するのを防止することができる。即ち、乗場の熱が昇降路内に伝わるのを、より確実に防止することができる。   In such a landing / entrance device, when the landing / entrance facing portion 22b is heated by a fire generated on the landing side, the heat is conducted to the vertical frame main body hoistway facing portion 22c. However, since the large opening 22e is provided in the vertical frame main body hoistway facing portion 22c, there are few portions that conduct heat. The opening 22e is shielded by the vertical frame heat insulating material 24. Therefore, it is possible to prevent the equipment in the hoistway from being heated and ignited by the heat of the vertical frame main body hoistway facing portion 22c. That is, it is possible to more reliably prevent the heat of the landing from being transmitted into the hoistway.

また、縦枠本体２２内の温度分布は、熱源に近い乗場出入口対向部２２ｂが最も高くなり、乗場出入口対向部２２ｂから離れるに従って低くなる。そして、取付金具２５は、乗場出入口対向部２２ｂから遠い折曲部２２ｄ及び塞ぎ板２３とに固定されているので、取付金具２５が高温になるのも防止することができる。しかも、取付金具２５に伝導した熱は、取付金具２５の昇降路側に配置された縦枠断熱材２４により遮断することができる。
なお、開口２２ｅは、上下方向に複数に分割されていてもよい。Further, the temperature distribution in the vertical frame body 22 is highest at the landing entrance facing portion 22b close to the heat source, and becomes lower as the distance from the landing entrance facing portion 22b increases. And since the mounting bracket 25 is being fixed to the bending part 22d and the closing board 23 which are distant from the landing entrance opposing part 22b, it can also prevent that the mounting bracket 25 becomes high temperature. Moreover, the heat conducted to the mounting bracket 25 can be blocked by the vertical frame heat insulating material 24 disposed on the hoistway side of the mounting bracket 25.
The opening 22e may be divided into a plurality of parts in the vertical direction.

For example, a gap of about 5 mm is secured between the second end portion 35b and the vertical frame main body hoistway facing portion 32c.

昇降路対向部の一部である塞ぎ板２３の裏面には、第２の縦枠断熱材３６が接合されている。第２の縦枠断熱材３６は、戸当側縦枠３１の上下方向の全体に渡って連続して設けられている。また、第２の縦枠断熱材３６は、断面略Ｚ字形の複数のブラケット３７ａ，３７ｂにより塞ぎ板３３との間に挟持されている。ブラケット３７ａ，３７ｂは、ねじ又はリベットにより塞ぎ板３３に固定されている。   A second vertical frame heat insulating material 36 is joined to the back surface of the closing plate 23 which is a part of the hoistway facing portion. The 2nd vertical frame heat insulating material 36 is provided continuously over the whole up-down direction of the doorhold side vertical frame 31. As shown in FIG. Further, the second vertical frame heat insulating material 36 is sandwiched between the closing plate 33 by a plurality of brackets 37 a and 37 b having a substantially Z-shaped cross section. The brackets 37a and 37b are fixed to the closing plate 33 with screws or rivets.

このような乗場出入口装置では、乗場側で発生した火災により乗場出入口対向部３２ｂが加熱されると、その熱が縦枠本体昇降路対向部３２ｃに伝導する。しかし、縦枠本体昇降路対向部３２ｃには第１の縦枠断熱材３４が取り付けられているので、縦枠本体昇降路対向部３２ｃの熱により昇降路内の機器が加熱され発火するのを防止することができる。即ち、乗場の熱が昇降路内に伝わるのを、より確実に防止することができる。   In such a landing / entrance device, when the landing / entrance facing portion 32b is heated by a fire generated on the landing side, the heat is conducted to the vertical frame main body hoistway facing portion 32c. However, since the first vertical frame heat insulating material 34 is attached to the vertical frame main body hoistway facing portion 32c, the equipment in the hoistway is heated and ignited by the heat of the vertical frame main body hoistway facing portion 32c. Can be prevented. That is, it is possible to more reliably prevent the heat of the landing from being transmitted into the hoistway.

また、乗場出入口対向部３２ｂの熱は、戸当側縦枠３１の内側にも放射されるが、塞ぎ板３３に第２の縦枠断熱材３６が取り付けられているので、塞ぎ板３３が高温になるのが防止され、これにより乗場の熱が昇降路内に伝わるのをより確実に防止することができる。   Further, the heat at the landing entrance facing portion 32b is also radiated to the inside of the door-holding side vertical frame 31, but since the second vertical frame heat insulating material 36 is attached to the closing plate 33, the closing plate 33 has a high temperature. This prevents the heat of the landing from being transmitted to the hoistway more reliably.

なお、上記の例では、戸当側縦枠３，２１，３１のみに縦枠断熱材１８，２４，３４，３６を設けたが、戸袋側縦枠４の昇降路内に臨む部分、即ち昇降路対向部の面積が大きい場合には、縦枠断熱材に縦枠断熱材を設けてもよい。
また、上記の例では、片開き式の乗場出入口装置を示したが、この発明は中央開き式の乗場出入口装置にも適用できる。但し、通常、片開き式の乗場出入口装置の戸当側縦枠３，２１，３１は、昇降路対向部の面積が大きいので、縦枠断熱材の設置が特に有効である。In the above example, the vertical frame heat insulating materials 18, 24, 34, 36 are provided only on the door-holding side vertical frames 3, 21, 31. When the area of the road facing portion is large, the vertical frame heat insulating material may be provided with a vertical frame heat insulating material.
In the above example, a single-opening type hall entrance / exit device is shown, but the present invention can also be applied to a center-opening type hall entrance / exit device. However, since the area of the hoistway facing portion is usually large in the door-holding vertical frames 3, 21, and 31 of the single-opening type hall entrance / exit device, installation of the vertical frame heat insulating material is particularly effective.
