In addition, in the landing door device having the above landing door as a main part, fire resistance and heat insulation are prevented in order to prevent a fire generated on a predetermined floor from spreading along the hoistway to other floors. An improvement is proposed.
[0003] 図 12は従来のエレベータの乗場ドア装置を示す平面図、図 13は従来のエレべ一 タの乗場ドア装置を示す側面図であり、所定の耐火性と断熱性とを備えた従来の乗 場ドア装置を示している。図 12及び図 13において、 1はエレベータの乗場に立設さ れた乗場三方枠の縦枠、 2は両縦枠 1の上端部間に跨って設けられた乗場三方枠の 上枠であり、この乗場三方枠と乗場の床面 3とによって乗場出入口が形成されている 。そして、上記乗場出入口を開閉する乗場ドア 4は、通常、横断面略四角筒状を呈す るドアパネルによって外形が形成され、その中空内部に、乗場ドア 4の断熱性を向上 させるための断熱材 6が設けられている。また、乗場ドア 4の側縁部及び上縁部には 、乗場三方枠の縦枠 1及び上枠 2に対向する熱遮蔽板 29及び 30が設けられ、乗場 ドア 4の耐火性の向上が図られている。  FIG. 12 is a plan view showing a conventional elevator landing door device, and FIG. 13 is a side view showing the conventional elevator landing door device, which has a predetermined fire resistance and heat insulation. The landing door device is shown. In FIGS. 12 and 13, 1 is a vertical frame of the landing three-way frame standing on the elevator landing, 2 is an upper frame of the landing three-way frame provided between the upper ends of both vertical frames 1, A landing entrance is formed by the three-way frame of the landing and the floor 3 of the landing. The landing door 4 that opens and closes the landing doorway is generally formed by a door panel having a substantially square cylindrical cross section, and a heat insulating material 6 for improving the heat insulating property of the landing door 4 in the hollow interior. Is provided. In addition, heat shielding plates 29 and 30 facing the vertical frame 1 and the upper frame 2 of the landing three-way frame are provided at the side edge and the upper edge of the landing door 4, thereby improving the fire resistance of the landing door 4. It has been.
[0004] なお、エレベータの乗場ドア装置の他の従来技術として、上記と同様の構成を有す る熱遮蔽板を備えて乗場ドアの耐火性を向上させるとともに、乗場ドアの乗場側に面 する表板と乗場ドアの昇降路側に面する裏板との間に断熱材を介在させて、乗場ド ァの断熱性を向上させたものが提案されている (例えば、特許文献 1参照)。  [0004] As another prior art of the elevator landing door device, a heat shield plate having the same configuration as described above is provided to improve the fire resistance of the landing door and face the landing side of the landing door. There has been proposed a heat insulating material interposed between a front plate and a back plate facing the hoistway side of the landing door to improve the heat insulating property of the landing door (see, for example, Patent Document 1).

発明の開示  Disclosure of the invention
発明が解決しょうとする課題 [0006] 乗場ドアの裏側の表面温度は、乗場ドアの表面 (加熱面)から直線的に伝わる、即 ち、図 12及び図 13に示す従来の乗場ドア装置においては、乗場ドア 4の表面から断 熱材 6を介して裏側の裏板 31に伝わる熱伝達と、ドアパネルや図示しない補強板等 を介して裏板 31に伝わる熱伝達 (ヒートブリッジ)とによって決まってしまう。したがって 、図 12及び図 13に示す従来の乗場ドア装置では、乗場ドア 4の外形を形成するドア パネルが横断面略四角筒状を呈しているため、ヒートブリッジによる熱伝達を抑制す ることができず、乗場ドア 4の裏側の表面温度が高くなるといった問題があった。 Problems to be solved by the invention [0006] The surface temperature on the back side of the landing door is transmitted linearly from the surface (heating surface) of the landing door. That is, in the conventional landing door apparatus shown in FIGS. It is determined by heat transfer transmitted to the back plate 31 via the heat insulating material 6 and heat transfer (heat bridge) transferred to the back plate 31 via a door panel, a reinforcing plate (not shown) or the like. Therefore, in the conventional landing door device shown in FIG. 12 and FIG. 13, the door panel forming the outer shape of the landing door 4 has a substantially rectangular tube shape in cross section, so that heat transfer by the heat bridge can be suppressed. There was a problem that the surface temperature on the back side of the landing door 4 became high.
[0007] また、特許文献 1記載のものでは、乗場ドアの表板と裏板との間に断熱材が介在さ れているため、乗場ドアの裏側の表面温度を抑制することが可能となるが、断熱材を 中間部に介在させる構造が複雑となるといつた問題があった。  [0007] In addition, in the one described in Patent Document 1, since the heat insulating material is interposed between the front plate and the back plate of the landing door, the surface temperature on the back side of the landing door can be suppressed. However, there was a problem when the structure of interposing the heat insulating material in the middle became complicated.
[0008] この発明は、上述のような課題を解決するためになされたもので、その目的は、簡 単な構成により、乗場ドアの裏側の温度上昇を抑制することができるエレベータの乗 場ドア装置を提供することである。  [0008] The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a landing door for an elevator that can suppress a temperature rise on the back side of the landing door with a simple configuration. Is to provide a device.

[0022] そして、第 1の固定部材 7は、第 2の板状部 18が、第 1の板状部 17の一側部が裏面 部 14に接触するまで、昇降路側、即ち、乗場ドア 4の裏側力も裏面部 14と断熱材 6 の一端面 6bとの間に挿入され、その後、第 1の板状部 17の一側部が裏面部 14に溶 接等により固定される。なお、第 1の固定部材 7は、上記位置に固定されることにより、 第 2の板状部 18が断熱材 6の一端面 6bに対向し、第 1の板状部 17の他側部が断熱 材 6の裏面 6aの一側部に昇降路側から対向するように配置される。一方、第 2の固定 部材 8も第 1の固定部材 7と同様に固定される。即ち、第 2の固定部材 8は、第 2の板 状部 18が、第 1の板状部 17の一側部が裏面部 15に接触するまで、昇降路側から裏 面部 15と断熱材 6の他端面との間に挿入され、その後、第 1の板状部 17の一側部が 裏面部 15に溶接等により固定される。なお、第 2の固定部材 8は、上記位置に固定さ れることにより、第 2の板状部 18が断熱材 6の他端面に対向し、第 1の板状部 17の他 側部が断熱材 6の裏面 6aの他側部に昇降路側力 対向するように配置される。  [0022] Then, the first fixing member 7 has the second plate-like portion 18 until the side of the hoistway, that is, the landing door 4 until one side of the first plate-like portion 17 contacts the back surface portion 14. The back side force is also inserted between the back surface portion 14 and the one end surface 6b of the heat insulating material 6, and thereafter, one side portion of the first plate-like portion 17 is fixed to the back surface portion 14 by welding or the like. The first fixing member 7 is fixed at the above position so that the second plate-like portion 18 faces the one end surface 6b of the heat insulating material 6 and the other side portion of the first plate-like portion 17 is fixed. It arrange | positions so that the one side part of the back surface 6a of the heat insulating material 6 may oppose from the hoistway side. On the other hand, the second fixing member 8 is also fixed in the same manner as the first fixing member 7. In other words, the second fixing member 8 has the second plate-like portion 18 between the back surface portion 15 and the heat insulating material 6 from the hoistway side until one side portion of the first plate-like portion 17 contacts the back surface portion 15. Inserted between the other end surface, and then one side portion of the first plate-like portion 17 is fixed to the back surface portion 15 by welding or the like. The second fixing member 8 is fixed at the above position so that the second plate-like portion 18 faces the other end surface of the heat insulating material 6 and the other side portion of the first plate-like portion 17 is thermally insulated.

As long as at least one of the end portions is fixed by the first fixing member 7 or the second fixing member 8, the same effect as described above can be obtained. For example, when the heat insulating material 6 is fixed using only the second fixing member 8, the heat insulating material 6 having a width slightly larger than the width of the opening 16 is disposed inside the door panel 5. The second fixing member 8 may be fixed to the back surface portion 15 of the door panel 5 by the same fixing method as described above. In such a case, the one end surface 6b of the heat insulating material 6 is disposed in a U-shaped portion composed of the front surface portion 11, the end surface portion 12, and the back surface portion 14 of the door panel 5, and faces the other side surface of the end surface portion 12.
