Description

本発明はエレベーター装置に用いられる乗場ドア装置、特に乗場ドアの耐火性能の向上に関する。   The present invention relates to a landing door device used in an elevator apparatus, and more particularly to improvement of fire resistance performance of a landing door.

一般にエレベーター出入口構造は、乗場側に設置された乗場ドアと乗場ドアを吊るすハンガーとハンガーに取り付けられたハンガーローラとハンガーローラが走行するためのレールと建屋に固定された三方枠を形成する上方に向かって立ち上がった立設板を含んだ上枠からなっている。このエレベーター出入口構造に耐火性能を持たせて火災時に炎が昇降路内に進入するのを防止するために例えば、特開平４−２７２０８６号公報は乗場ドアと隙間を隔てて立設され出入口の上枠との間に乗場側からの遮へい板が形成され相じゃくり構造としていた。   Generally, the elevator entrance / exit structure has a landing door installed on the landing side, a hanger that hangs the landing door, a hanger roller attached to the hanger, a rail for the hanger roller to travel, and a three-way frame fixed to the building. It consists of an upper frame that includes a standing plate that stands up. For example, Japanese Laid-Open Patent Application No. 4-27286 is provided with a clearance between the landing door and the entrance to prevent the flame from entering the hoistway in the event of a fire. A shielding board from the landing side was formed between the frame and the structure was a ladle structure.

特開平４−２７２０８６号公報Japanese Patent Laid-Open No. 4-272086

エレベーターの耐火性能を判定する基準の一つに乗場ドアに対して乗場側から火にさらして、昇降路側から確認をおこない１０秒以上発火しないことというものがある。上記のような従来のエレベーター出入口構造では乗場側に面した建物内部で火災が発生するとハンガーローラを形成する樹脂が熱風あるいは伝熱により融解して落下し、落下先の乗場ドア構成物が樹脂の発火点温度を超えていると発火してしまい判定基準を満足出来ないことがあるといった課題があった。   One of the criteria for judging the fire resistance performance of an elevator is that the landing door is exposed to fire from the landing side, checked from the hoistway side and not ignited for more than 10 seconds. In the conventional elevator entrance / exit structure as described above, if a fire occurs inside the building facing the landing side, the resin that forms the hanger roller melts and drops due to hot air or heat transfer, and the landing door structure at the destination is the resin When the ignition point temperature is exceeded, there is a problem in that it may ignite and the determination criteria may not be satisfied.

以下本発明の一実施例を図１，図２，図３，図４に沿って説明する。   An embodiment of the present invention will be described below with reference to FIGS.

図１は一般的なエレベーター昇降路の全容を示した概要図である。昇降路１の中に乗りかご２と釣合いおもり３を設け、この乗りかご２と釣合いおもり３を主ロープ４によって接続し主ロープ４を巻上機５によって巻き上げることにより、乗りかご２と釣合いおもり３が逆方向に昇降するものである。建屋には各フロアに乗りかごに乗るための出入口が設けられている。この出入口構造は各フロアに備え付けられた乗場側出入口機構６とかごに備え付けられたかご側出入口機構７からなっている。   FIG. 1 is a schematic view showing the entire elevator hoistway. A car 2 and a counterweight 3 are provided in the hoistway 1, and the car 2 and the counterweight 3 are connected by a main rope 4 and the main rope 4 is wound up by a hoisting machine 5, so that the counterweight 2 and the counterweight are balanced. 3 moves up and down in the reverse direction. In the building, there are doorways for getting into the car on each floor. This entrance / exit structure includes a landing side entrance / exit mechanism 6 provided on each floor and a car side entrance / exit mechanism 7 provided on the car.

図２は一般的な乗場ドア構造を昇降路側から見た正面図となっている。この乗場側出入口機構６は乗場ドア８と乗場ドア８を吊るすハンガー９とハンガー９に取り付けられたハンガーローラ１０とハンガーローラ１０が走行するためのレール１１を設け、複数個の乗場ドア８の動きを連動させるためのドアベルト１２からなっている。なお以降の説明では乗場ドア８の乗場側面を表面、昇降路側の面を裏面とする。   FIG. 2 is a front view of a general landing door structure as seen from the hoistway side. The landing-side entrance / exit mechanism 6 includes a landing door 8, a hanger 9 for hanging the landing door 8, a hanger roller 10 attached to the hanger 9, and a rail 11 for the hanger roller 10 to travel, and the movement of the plurality of landing doors 8. It consists of a door belt 12 for interlocking. In the following description, the landing side surface of the landing door 8 is the front surface, and the hoistway side surface is the back surface.

図３は本発明の詳細を説明するために表した図２のＡ−Ａ断面図である。   3 is a cross-sectional view taken along the line AA of FIG. 2 for explaining the details of the present invention.

図４は本発明の詳細を説明するために表した図３のＣ−Ｃ断面図である。   4 is a cross-sectional view taken along the line CC of FIG. 3 for illustrating the details of the present invention.

乗場ドア８の上部とハンガー９の間にはＬ型の遮へい板１３が設けられておりＬ型の遮へい板１３の下向きの立設部は図３に示すように上枠の昇降路側面と乗場ドア８乗場側面の隙間に設けられている。このＬ型の遮へい板１３の立設部の乗場側面とこの乗場側面に対面する上枠１４の昇降路面の隙間は近接している。またこのＬ型の遮へい板１３と乗場ドア８の間にはワッシャー１５を設けボルト１６による締結部近傍以外では隙間を設けている。以降の説明ではＬ型遮へい板１３の立設部，コの字型の遮へい板１７の立設部及び上枠１４立設部それぞれの立設部について、図３の矢印と共に示すＳ,Ｂのように乗場側の面をＳ面、昇降路側面をＢ面と呼ぶこととする。   An L-shaped shielding plate 13 is provided between the upper part of the landing door 8 and the hanger 9, and the downward standing portion of the L-shaped shielding plate 13 is formed on the side of the hoistway of the upper frame and the landing as shown in FIG. It is provided in the clearance of the side surface of the door 8 landing. The clearance between the landing side surface of the standing portion of the L-shaped shielding plate 13 and the hoistway surface of the upper frame 14 facing the landing side surface is close to each other. Further, a washer 15 is provided between the L-shaped shielding plate 13 and the landing door 8, and a gap is provided except in the vicinity of the fastening portion by the bolt 16. In the following description, the standing part of the L-shaped shielding plate 13, the standing part of the U-shaped shielding plate 17, and the standing part of the upper frame 14 standing part are shown in S and B together with the arrows in FIG. Thus, the surface on the landing side is referred to as the S surface, and the hoistway side surface is referred to as the B surface.

コの字型の遮へい板１７はＬ型遮へい板１３とハンガー９の間に設けられている。このコの字型の遮へい板１７は下向きの立設部の内側面が乗場ドア８裏面と上枠１４立設部のＳ面にそれぞれ対面するように設けられ、コの字型の遮へい板１７の乗場側立設部Ｂ面とこのＢ面に対面する上枠１４立設部のＳ面の隙間は近接している。コの字型の遮へい板１７とＬ型遮へい板１３の間ワッシャー１５を設けボルト１６による締結部近傍以外では隙間を設けている。各遮へい板と上枠の立設部の隙間は３ｍｍ以下であるのがよい。また互いに接触しない範囲で隙間を設けることがよい。接触してしまうとドアの開閉を阻害してしまうためである。   The U-shaped shielding plate 17 is provided between the L-shaped shielding plate 13 and the hanger 9. The U-shaped shielding plate 17 is provided so that the inner side surface of the downward standing portion faces the back surface of the landing door 8 and the S surface of the upper frame 14 erected portion, and the U-shaped shielding plate 17. The clearance between the B-side standing portion B surface and the S surface of the upper frame 14 standing portion facing this B surface is close to each other. A washer 15 is provided between the U-shaped shielding plate 17 and the L-shaped shielding plate 13, and a gap is provided except in the vicinity of the fastening portion by the bolt 16. The gap between each shielding plate and the upright portion of the upper frame is preferably 3 mm or less. Moreover, it is good to provide a clearance gap in the range which does not contact mutually. This is because if it comes in contact with the door, opening and closing of the door is hindered.

このように構成されたエレベーターの出入口構造において、火災時に熱風はＬ型遮へい板１３により乗場ドア８とＬ型遮へい板１３の間あるいは上枠１４とＬ型遮へい板１３の間を通過する。しかしＬ型の遮へい板１３の立設部のＳ面とこの乗場側面に対面する上枠１４立設部のＢ面の隙間は近接しているため、熱風の大部分は乗場ドア８とＬ型遮へい板１３の隙間を通り昇降路内へ流れていく。上枠１４とＬ型遮へい板１３の間を通過した熱風はコの字型の遮へい板１７にあたり昇降路側あるいは上枠側に分かれる。しかしコの字型の遮へい板１７の乗場側立設部のＢ面と、この昇降路側面に対面する上枠１４立設部のＳ面の隙間は近接している。そのため熱風の大部分はコの字型の遮へい板１７とＬ型遮へい板１３の隙間をとおり昇降路内へ流れていく。   In the elevator entrance / exit structure configured as described above, hot air passes between the landing door 8 and the L-shaped shielding plate 13 or between the upper frame 14 and the L-shaped shielding plate 13 by the L-shaped shielding plate 13 in the event of a fire. However, since the gap between the S surface of the standing portion of the L-shaped shielding plate 13 and the B surface of the standing portion of the upper frame 14 facing the landing side surface is close, most of the hot air is in contact with the landing door 8 and the L shape. It flows into the hoistway through the gap of the shielding plate 13. The hot air that has passed between the upper frame 14 and the L-shaped shielding plate 13 hits the U-shaped shielding plate 17 and is divided into the hoistway side or the upper frame side. However, the gap between the B surface of the landing side standing portion of the U-shaped shielding plate 17 and the S surface of the upper frame 14 standing portion facing the side surface of the hoistway are close to each other. Therefore, most of the hot air flows into the hoistway through the gap between the U-shaped shielding plate 17 and the L-shaped shielding plate 13.

これら構造によって熱風の大部分はＬ型遮へい板１３が受け昇降路内へ流れる。それによりコの字型の遮へい板１７は当たる熱風量が減少する。さらに乗場ドア８-Ｌ型遮へい板１３-コの字型遮へい板１７それぞれの間には隙間が設けられているため伝熱量も減少する。そのためハンガーローラ１０を形成しているハンガーローラ樹脂１８が融解し落下した場合でも落下先にある、コの字型遮へい板１７はＬ型の遮へい板１３がハンガーローラ樹脂１８の発火点温度に達しにくくなる。   With these structures, most of the hot air is received by the L-shaped shielding plate 13 and flows into the hoistway. Thereby, the amount of hot air hitting the U-shaped shielding plate 17 is reduced. Further, since a clearance is provided between the landing door 8-L type shielding plate 13 and the U-shaped shielding plate 17, the amount of heat transfer is also reduced. Therefore, even when the hanger roller resin 18 forming the hanger roller 10 is melted and dropped, the U-shaped shielding plate 17 at the dropping destination reaches the ignition point temperature of the hanger roller resin 18 at the L-shaped shielding plate 13. It becomes difficult.

さらにハンガーローラ樹脂１８へ当たる熱風の量、伝熱量も同様に減少するためハンガーローラ樹脂１８の融解による落下を抑制する効果もある。   Further, since the amount of hot air hitting the hanger roller resin 18 and the amount of heat transfer are similarly reduced, the hanger roller resin 18 can be prevented from dropping due to melting.

さらにコの字型遮へい板１７の昇降路側立設部のＳ面と乗場ドア８裏面が対面しているため乗場ドア８-Ｌ型遮へい板１３-コの字型遮へい板１７それぞれの間には隙間から炎が噴出しても昇降路側から炎が確認されない。   Further, since the S surface of the hoistway side standing part of the U-shaped shielding plate 17 and the rear surface of the landing door 8 face each other, there is a landing door 8-L type shielding plate 13-between each U-shaped shielding plate 17. Even if a flame is ejected from the gap, no flame is confirmed from the hoistway side.

次に図５を用いて本発明による実施例２を説明する。尚、図５において、図３と同一の部品については同一符号を付して説明を省略する。実施例１では、下から上に向かって乗場ドア８-Ｌ型遮へい板１３-コの字遮へい板１７の順で構成されていたが、実施例２では、乗場ドア８-コの字型遮へい板１７-Ｌ型遮へい板１３の順で構成されており、乗場ドア８-コの字型遮へい板１７-Ｌ型遮へい板１３のそれぞれの間にはワッシャー１５を設けボルト１６による締結部近傍以外では隙間を設けている。コの字型遮へい板１７は乗場側立設部のＢ面と上枠１４立設部のＳ面が対面し近接するように設けられている。コの字型遮へい板１７と上枠の立設部１４の隙間は３ｍｍ以下であるのがよい。また互いに接触しない範囲で隙間を設けることがよい。接触してしまうとドアの開閉を阻害してしまうためである。   Next, Embodiment 2 according to the present invention will be described with reference to FIG. In FIG. 5, the same parts as those in FIG. In the first embodiment, the landing door 8-L type shielding plate 13-U-shaped shielding plate 17 is arranged in order from the bottom to the top. In Example 2, the landing door 8-L shape shielding plate 17 is configured in this order. The plate 17-L type shielding plate 13 is configured in this order, and a washer 15 is provided between each of the landing doors 8-U-shaped shielding plate 17-L type shielding plate 13 except for the vicinity of the fastening portion by the bolt 16 Then there is a gap. The U-shaped shielding plate 17 is provided so that the B surface of the landing side standing portion and the S surface of the upper frame 14 standing portion face each other and are close to each other. The gap between the U-shaped shielding plate 17 and the upright portion 14 of the upper frame is preferably 3 mm or less. Moreover, it is good to provide a clearance gap in the range which does not contact mutually. This is because if it comes in contact with the door, opening and closing of the door is hindered.

この構造により火災時に熱風の大部分はコの字型の遮へい板１７の乗場側立設部のＢ面とこのＢ面に対面する上枠１４立設部のＳ面の隙間は近接しているため、乗場ドア８とコの字型遮へい板１７の隙間を通り昇降路内へ流れるため、ハンガーローラー樹脂１８が融解した際に落下する上方のＬ型の遮へい板１３は当たる熱風量が減少する。   Due to this structure, most of the hot air during a fire is close to the gap between the B surface of the landing side standing portion of the U-shaped shielding plate 17 and the S surface of the standing portion of the upper frame 14 facing this B surface. Therefore, since it flows into the hoistway through the gap between the landing door 8 and the U-shaped shielding plate 17, the amount of hot air hitting the upper L-shaped shielding plate 13 that falls when the hanger roller resin 18 melts decreases. .

前記実施例1では乗場ドア８とＬ型遮へい板１３の隙間を通った熱風がそのまま昇降路側からＬ型遮へい板１３とコの字型遮へい板１８の隙間へ侵入することが考えられたが、本実施例ではＬ型遮へい板１３がコの字型遮へい板１８よりも上部に設けられることにより、Ｌ型遮へい板１３とコの字型遮へい板１８の隙間へ侵入しづらいといった利点がある。   In Example 1, it was considered that the hot air that passed through the gap between the landing door 8 and the L-shaped shielding plate 13 entered the gap between the L-shaped shielding plate 13 and the U-shaped shielding plate 18 as it was from the hoistway side. In this embodiment, since the L-shaped shielding plate 13 is provided above the U-shaped shielding plate 18, there is an advantage that it is difficult to enter the gap between the L-shaped shielding plate 13 and the U-shaped shielding plate 18.

次に図６を用いて本発明による実施例３を説明する。尚、図６において、図３と同一の部品については同一符号を付して説明を省略する。本実施例では乗場ドア８とハンガー９の間に、Ｌ型遮蔽板１３を２枚設ける。この乗場ドア８及びＬ型遮へい板１３の間にはワッシャー１５を設けボルト１６による締結部近傍以外では隙間を設けている。２枚のＬ型遮へい板１３は下側のＬ型遮へい板１３ａの立設部Ｓ面と上側のＬ型遮へい板１３ｂ立設部のＢ面とで上枠１４立設部を挟むように近接して設けている。各遮へい板と上枠の立設部の隙間は３ｍｍ以下であるのがよい。また互いに接触しない範囲で隙間を設けることがよい。接触してしまうとドアの開閉を阻害してしまうためである。   Next, Embodiment 3 according to the present invention will be described with reference to FIG. In FIG. 6, the same components as those in FIG. In this embodiment, two L-shaped shielding plates 13 are provided between the landing door 8 and the hanger 9. A washer 15 is provided between the landing door 8 and the L-shaped shielding plate 13, and a gap is provided except in the vicinity of the fastening portion by the bolt 16. The two L-shaped shielding plates 13 are close to each other so that the upper frame 14 standing portion is sandwiched between the standing surface S of the lower L-shaped shielding plate 13a and the B surface of the upper L-shaped shielding plate 13b. Provided. The gap between each shielding plate and the upright portion of the upper frame is preferably 3 mm or less. Moreover, it is good to provide a clearance gap in the range which does not contact mutually. This is because if it comes in contact with the door, opening and closing of the door is hindered.

この構造は熱風の大部分を下側のＬ型遮へい板１３ａが受け、２枚のＬ型遮へい板１３が上枠立設部を挟むように設けられているためハンガーローラ樹脂１８が融解し落下する上側Ｌ型遮へい板１３ｂに熱風が当たりにくくなっている。上記の実施例１及び実施例２と異なり乗場ドアの昇降路側に立設部がないため熱風が昇降路側に流れやすいといった利点がある。   In this structure, most of the hot air is received by the lower L-shaped shielding plate 13a, and the two L-shaped shielding plates 13 are provided so as to sandwich the upper frame standing portion, so that the hanger roller resin 18 melts and falls. It is difficult for hot air to hit the upper L-shaped shielding plate 13b. Unlike Example 1 and Example 2 above, there is no standing part on the hoistway side of the landing door, so there is an advantage that hot air easily flows to the hoistway side.

次に図７を用いて本発明による実施例４を説明する。尚、図７において、図３と同一の部品については同一符号を付して説明を省略する。本実施例では下から上に向かって乗場ドア８-Ｌ型遮蔽板１３-平板遮へい板１９-ハンガー９の順で構成されている。なお乗場ドア８-Ｌ型遮蔽板１３-平板遮へい板１９の間にはワッシャー１５を設けボルト１６による締結部近傍以外では隙間を設けている。Ｌ型遮へい板１３はこの立設部Ｂ面と上枠１４の立設部Ｓ面と対面し近接するように設けている。Ｌ型遮へい板と上枠の立設部の隙間は３ｍｍ以下であるのがよい。また互いに接触しない範囲で隙間を設けることがよい。接触してしまうとドアの開閉を阻害してしまうためである。   Next, Embodiment 4 according to the present invention will be described with reference to FIG. In FIG. 7, the same components as those in FIG. In this embodiment, the landing door 8-L type shielding plate 13-the flat plate shielding plate 19-the hanger 9 are arranged in this order from bottom to top. A washer 15 is provided between the landing door 8-L type shielding plate 13 and the flat plate shielding plate 19, and a gap is provided except in the vicinity of the fastening portion by the bolt 16. The L-shaped shielding plate 13 is provided so as to face and be close to the surface B of the standing portion and the surface S of the upper frame 14. The gap between the L-shaped shielding plate and the standing portion of the upper frame is preferably 3 mm or less. Moreover, it is good to provide a clearance gap in the range which does not contact mutually. This is because if it comes in contact with the door, opening and closing of the door is hindered.

この構造は熱風をＬ型遮へい板１３が受けＬ型遮へい板１３立設部Ｂ面と上枠１４の立設部Ｓ面と対面し近接するように設けているため、ハンガーローラ樹脂１８が融解し落下する平板遮へい板１９に熱風が当たりにくくなっている。平板遮へい板１９は上記実施例１〜３にあげた遮へい板と異なり曲げ構造ではないため、生産面で利点がある。   In this structure, the hot air is received by the L-shaped shielding plate 13 so as to face the L-shaped shielding plate 13 standing portion B surface and the standing portion S surface of the upper frame 14 so that the hanger roller resin 18 is melted. Then, the hot air does not easily hit the falling flat plate shielding plate 19. Unlike the shielding plates described in the first to third embodiments, the flat shielding plate 19 is not a bent structure, and thus has an advantage in production.

上記実施例１から実施例４ではＬ型遮へい板とコの字型遮へい板のパターン、Ｌ型遮へい板２枚のパターン、Ｌ型遮へい板と平板のパターンを説明したが、本発明は実施例に限定されるものではなく、様々なパターンが含まれる。   In the first to fourth embodiments, the L-shaped shielding plate and the U-shaped shielding plate pattern, the two L-shaped shielding plate patterns, and the L-shaped shielding plate and flat plate pattern have been described. It is not limited to, and various patterns are included.
