Below, the fastening structure of an elevator cab is first described, and then the wall panel fastening tool is described.

（壁パネル）
図１は、実施の形態１における壁パネルの締結作業の様子を示す概略図である。壁パネルは、すでに昇降路に設置されたかご枠に対して据え付ける。図１は、壁パネル（側板）同士を仮り組みした状態において、作業者がかご室の天井に上がり、パネル同士を壁パネル締結工具１３を用いて締結している様子を示している。なお、壁パネルとは、かご室の側板のことであり、壁パネルあるいは正面壁、側面壁と呼ぶ場合がある。この場合、直方体形状のかご室であれば、「正面壁」とは、エレベータの扉１６に向かい合う側板をいい、「側面壁」とは、エレベータの扉１６と略直交して配置される側板をいう。 (Wall panel)
FIG. 1 is a schematic diagram showing a state of a wall panel fastening operation in the first embodiment. Wall panels are installed against the car frame already installed in the hoistway. FIG. 1 shows a state in which an operator goes up to the ceiling of a cab and fastens the panels using a wall panel fastening tool 13 in a state where the wall panels (side plates) are temporarily assembled. In addition, a wall panel is a side plate of a cab, and may be called a wall panel, a front wall, or a side wall. In this case, in the case of a rectangular parallelepiped cab, the “front wall” refers to a side plate facing the elevator door 16, and the “side wall” refers to a side plate disposed substantially orthogonal to the elevator door 16. Say.

（昇降路）
図２は、エレベータの昇降路の断面を示す図である。図２は、壁パネルを設置する際のかご位置における昇降路の断面である。すなわち、図２は、壁パネルの据付作業を行うかご枠の位置（高さ方向位置）の周辺を示している。図２において、昇降路１は、昇降路壁２に囲まれている。また、かご室６の周りには、巻上機、制御盤、カウンターウェイト等の昇降路機器３〜５が配置されている。図２では、エレベータの昇降路１が狭く、また周辺に巻上機や制御盤等の昇降路機器３〜５が配置されているため、かご室６の壁パネル（側板）を据え付ける際に、かご室６の壁パネルの裏面（昇降路側）に据え付け作業者が入り込むことが出来ない（作業スペースが無い）。 (Hoistway)
FIG. 2 is a cross-sectional view of the elevator hoistway. FIG. 2 is a cross section of the hoistway at the car position when installing the wall panel. That is, FIG. 2 shows the vicinity of the position (height direction position) of the car frame where the wall panel is installed. In FIG. 2, the hoistway 1 is surrounded by the hoistway wall 2. In addition, hoistway devices 3 to 5 such as a hoisting machine, a control panel, and a counterweight are disposed around the car room 6. In FIG. 2, the elevator hoistway 1 is narrow, and hoistway devices 3 to 5 such as a hoisting machine and a control panel are arranged around the elevator hoistway 1. When installing the wall panel (side plate) of the cab 6, The installation worker cannot enter the back surface (the hoistway side) of the wall panel of the cab 6 (there is no work space).

（かご室）
かご室６は、かご室６の側面側を覆う側面壁７−１（側板）〜７−３と、かご室６の正面側を覆う正面壁８−１、８−２等を備える。図２に示すように、正面壁８−１，８−２は、かご室６の扉１６に対向して設置されている。側面壁７−１は正面壁８−１に対し、昇降路１の上部からみて、略直交して締結される。実施の形態１では、正面壁８−１に対して側面壁７−１を締結する場合を説明する。すなわち、図２において、Ａ部における締結方式を説明する。正面壁８−１（第１の側板）が雄ネジ部を備えており、側面壁７−１（第２の側板）が皿バネ付きナット１２によって正面壁８−１に締結される場合を想定する。 (Cag room)
The cab 6 includes side walls 7-1 (side plates) to 7-3 that cover the side of the cab 6, and front walls 8-1 and 8-2 that cover the front of the cab 6. As shown in FIG. 2, the front walls 8-1 and 8-2 are installed to face the door 16 of the cab 6. The side wall 7-1 is fastened substantially orthogonal to the front wall 8-1 when viewed from the top of the hoistway 1. In the first embodiment, a case where the side wall 7-1 is fastened to the front wall 8-1 will be described. That is, in FIG. 2, the fastening method in part A will be described. It is assumed that the front wall 8-1 (first side plate) has a male screw part and the side wall 7-1 (second side plate) is fastened to the front wall 8-1 by a nut 12 with a disc spring. To do.

図３は、正面壁８−１と側面壁７−１とを締結する概要を示す図である。正面壁８−１には、ボルト１０が固定された「Ｌ字型の固定金具９」（以下、固定金具９という）が、上下方向（昇降路方向）の端部に接着等により固定されている。図３に示すように、正面壁８−１には固定金具９が既に取り付けられた状態で、側面壁７−１が正面壁８−１に締結される。正面壁８−１の上下方向の端部からは、ボルト１０の雄ネジ部１０ａ（雄ネジロッド）が意匠面から略垂直に突き出ている。ボルト１０は、正面壁８−１と側面壁７−１との締結用として、溶接等により固定金具９に固定されている。正面壁８−１には、複数（例えば５箇所程度）の固定金具９が取り付けられている。 FIG. 3 is a diagram showing an outline of fastening the front wall 8-1 and the side wall 7-1. On the front wall 8-1, an “L-shaped fixing bracket 9” (hereinafter referred to as a fixing bracket 9) to which the bolt 10 is fixed is fixed to an end portion in the vertical direction (the hoistway direction) by bonding or the like. Yes. As shown in FIG. 3, the side wall 7-1 is fastened to the front wall 8-1 with the fixing metal 9 already attached to the front wall 8-1. From the end in the vertical direction of the front wall 8-1, a male screw portion 10 a (male screw rod) of the bolt 10 protrudes substantially perpendicularly from the design surface. The bolt 10 is fixed to the fixture 9 by welding or the like for fastening the front wall 8-1 and the side wall 7-1. A plurality of (for example, about five) fixing brackets 9 are attached to the front wall 8-1.

一方、側面壁７−１には、雄ネジ部１０ａに対応する貫通穴７ｈが開けられており、雄ネジ部１０ａをこの貫通穴７ｈを通して、後述の壁パネル締結工具１３を用いることにより皿バネ付きナット１２を雄ネジ部１０ａにねじ込むことにより、正面壁８−１と側面壁７−１とが締結される。すなわち、側面壁７−１は、上下方向の端部が折り曲げられているとともに折り曲げられた端部側の平面に雄ネジ部１０ａが貫通する貫通穴７ｈを有する。そして、皿バネ付きナット１２が、側面壁７−１の貫通穴７ｈを貫通した雄ネジ部１０ａに対して、かごの天井にいる作業者の操作する後述の壁パネル締結工具１３によってねじ込まれることで、正面壁８−１と側面壁７−１とが締結される。 On the other hand, the side wall 7-1 has a through hole 7h corresponding to the male screw portion 10a, and the male screw portion 10a is passed through the through hole 7h to use a wall panel fastening tool 13, which will be described later. The front wall 8-1 and the side wall 7-1 are fastened by screwing the nut 12 into the male screw portion 10a. That is, the side wall 7-1 has a through hole 7h through which the male screw portion 10a penetrates in the plane of the bent end portion side while the end portion in the vertical direction is bent. And the nut 12 with a disc spring is screwed with respect to the external thread part 10a which penetrated the through-hole 7h of the side wall 7-1 with the below-mentioned wall panel fastening tool 13 which the operator who exists in the ceiling of a cage | basket | operator operates. Thus, the front wall 8-1 and the side wall 7-1 are fastened.

図４（ａ）は、図３の矢視Ｂを示す図である。図４（ｂ）は、雄ネジ部１０ａの拡大図である。図４（ａ）に示すように、正面壁８−１には、端部の上下方向に、複数（例えば５箇所程度）の固定金具９（ボルト１０が固着）が取り付けられている。なお、後述する図８（ａ）は、図４（ｂ）のＢ−Ｂ断面である。 FIG. 4A is a diagram showing an arrow B in FIG. FIG. 4B is an enlarged view of the male screw portion 10a. As shown in FIG. 4A, a plurality of (for example, about five) fixing brackets 9 (bolts 10 are fixed) are attached to the front wall 8-1 in the vertical direction of the end portion. Note that FIG. 8A, which will be described later, is a BB cross section of FIG. 4B.

（パネル据え付けの前提）
図３に示すように、パネルの据え付け作業においては、側面壁７−１〜側面壁７−３は互いに、既に締結されている。この状態で、正面壁８−１と側面壁７−１とが締結されることを想定している。これは、側面壁７−１〜側面壁７−３は、例えば、エレベータ乗場で締結することが可能であり、また、正面壁８−１、８−２等の据え付けは、かご床上で行なうことができるからである。結局、壁パネルの据え付け工程上、ネックとなるのが正面壁８−１と側面壁７−１との締結である。このため、正面壁８−１と側面壁７−１との締結を想定する。正面壁８−１と側面壁７−１との締結において、ボルト１０と皿バネ付きナット１２とはかご室６の室外側（昇降路側）にあるので、かご床上での締結はできない。また、昇降路側で作業しようとしても前述のように昇降路機器の存在により作業者の作業するスペースがない。また、昇降路機器の存在しない高さに「かご枠」を上昇させることも考えられるが、かご枠を上昇させると、昇降路機器の問題は解消しても、作業者の足場がない。結局、作業者は、図１に示した例のようにかごの天井、あるいはピット側から据え付け作業をせざるを得ない。 (Prerequisite for panel installation)
As shown in FIG. 3, in the panel installation operation, the side wall 7-1 to the side wall 7-3 are already fastened to each other. In this state, it is assumed that the front wall 8-1 and the side wall 7-1 are fastened. For example, the side wall 7-1 to the side wall 7-3 can be fastened at the elevator hall, and the front walls 8-1 and 8-2 are installed on the car floor. Because you can. After all, the fastening of the front wall 8-1 and the side wall 7-1 becomes a neck in the process of installing the wall panel. For this reason, fastening with the front wall 8-1 and the side wall 7-1 is assumed. When the front wall 8-1 and the side wall 7-1 are fastened, the bolt 10 and the nut 12 with a disc spring are on the outside (the hoistway side) of the car room 6, so that the fastening on the car floor is not possible. Moreover, even if it is going to work on the hoistway side, there is no space for the operator to work due to the presence of hoistway equipment as described above. Although it is conceivable to raise the “car frame” to a height at which no hoistway device exists, if the car frame is raised, the problem of the hoistway device is solved, but there is no scaffolding for the operator. Eventually, the worker is forced to perform the installation work from the ceiling of the car or the pit side as in the example shown in FIG.

なお、図５に示すように、側面壁７−１〜側面壁７−３の締結方式は、正面壁８−１と側面壁７−１との締結方式と同じ方式をとっても構わない。また、正面壁８−１と正面壁８−２との締結方式も、正面壁８−１と側面壁７−１との締結方式と同じ方式をとっても構わない。 As shown in FIG. 5, the fastening method of the side wall 7-1 to the side wall 7-3 may be the same as the fastening method of the front wall 8-1 and the side wall 7-1. The fastening method between the front wall 8-1 and the front wall 8-2 may be the same as the fastening method between the front wall 8-1 and the side wall 7-1.

（壁パネル締結工具１３の構成）
図６は、壁パネル締結工具１３の構成を示す図である。図６（ａ）は、正面図、（ｂ）は左側面図、（ｃ）は底面図である。図６を参照して、壁パネル締結工具１３を説明する。壁パネル締結工具１３は、ブロック１３ｅ（ベース）と、自己の軸線回りに回転可能にブロック１３ｅに取り付けられた軸１３ｃ（第１軸）と、自己の軸線回りに回転可能、かつ、軸１３ｃと略直交する方向にブロック１３ｅに取り付けられた軸１３ｇ（第２軸）と、軸１３ｃの回転を軸１３ｇに伝動する伝動機構を形成する歯車１３ｆ及び歯車１３ｈと、皿バネ付きナット１２を着脱可能に半固定的に保持するとともに軸１３ｇの一方の先端に取り付けられ、歯車１３ｆ及び歯車１３ｈとで形成される伝動機構により伝動された軸１３ｃの回転に基づき回転する軸１３ｇの回転により皿バネ付きナット１２を正面壁８−１に取り付けられた雄ネジ部１０ａにねじ込むソケット１３ｉ（ナット受け部）と、ブロック１３ｅに固着されるとともに、軸１３ｃが貫通するパイプ形状であり、パイプ形状の長手方向の途中に取っ手を取り付ける回転防止部材１３ｊ（取っ手取付部）を有するパイプカバー１３ｄ（パイプ部）とを備える。 (Configuration of wall panel fastening tool 13)
FIG. 6 is a view showing a configuration of the wall panel fastening tool 13. 6A is a front view, FIG. 6B is a left side view, and FIG. 6C is a bottom view. The wall panel fastening tool 13 will be described with reference to FIG. The wall panel fastening tool 13 includes a block 13e (base), a shaft 13c (first shaft) attached to the block 13e so as to be rotatable about its own axis, a shaft 13c that is rotatable about its own axis, and the shaft 13c. A shaft 13g (second shaft) attached to the block 13e in a substantially orthogonal direction, a gear 13f and a gear 13h forming a transmission mechanism for transmitting the rotation of the shaft 13c to the shaft 13g, and a nut 12 with a disc spring can be attached and detached. And is attached to one end of the shaft 13g, and is provided with a disc spring by the rotation of the shaft 13g that rotates based on the rotation of the shaft 13c transmitted by the transmission mechanism formed by the gear 13f and the gear 13h. A socket 13i (nut receiving portion) for screwing the nut 12 into a male screw portion 10a attached to the front wall 8-1 and a block 13e are fixed. A pipe-shaped shaft 13c penetrates, and a pipe cover 13d (pipe portion) having a rotation preventing member 13j for mounting a handle in the middle of the longitudinal direction of the pipe-shaped (handle mounting portion).

（１）図６に示すように、取っ手１３ａは、中心部上側に六角棒１３ｂが溶接等により固定されている。軸１３ｃは、取っ手１３ａに溶接等により固定され、ブロック１３ｅにあけられた穴を貫通し、貫通した先端には、歯車１３ｆ（マイタ歯車）が固定されている。軸１３ｃは、パイプ形状の軸である。中実材でも構わないが、重量の点で中空材（パイプ形状）が好ましい。パイプカバー１３ｄは、一端がブロック１３ｅに溶接等により固定されており、軸１３ｃと微小な隙間を保ち軸１３ｃを支える。ブロック１３ｅは、直角に交差する軸用穴を有しており、一方の軸用穴には軸１３ｃが挿入され、他方の軸用穴には、軸１３ｇが挿入されている。軸１３ｇは、ブロック１３ｅの軸用穴に挿入されることにより軸１３ｃと直角に配置される。歯車１３ｆの側には軸１３ｃの回転方向を９０度方向を変えることが出来るように配置された歯車１３ｈ（マイタ歯車）が歯車１３ｆとかみ合うように固定されている。また、歯車１３ｈが取り付けられている端部と反対側の先端には、皿バネ付きナット１２を挿入・固定することが可能なソケット１３ｉを有する。
（２）ソケット１３ｉは、磁力あるいはバネ力などにとって、皿バネ付きナット１２を半固定的に保持する。「半固定的に保持する」とは、ソケット１３ｉが皿バネ付きナット１２を保持した場合には、ソケット１３ｉから重力により皿バネ付きナット１２が落下するのを防止しつつ、皿バネ付きナット１２が雄ネジ部１０ａにねじ込まれた場合には、ソケット１３ｉから皿バネ付きナット１２を取り出し可能な状態で保持することを意味する。
（３）また、正面壁８−１と側面壁７−１との締結時に、六角棒１３ｂをラチェット・レンチ等で回転させる場合に、本体の回転防止として回転防止部材１３ｊ（取っ手取付部）には、スパナ等の取っ手を差し込むことにより、壁パネル締結工具１３自体がラチェット・レンチから加えられるトルク方向に回転してしまうことを防止する。 (1) As shown in FIG. 6, the handle 13a has a hexagonal bar 13b fixed to the upper side of the center portion by welding or the like. The shaft 13c is fixed to the handle 13a by welding or the like, passes through a hole formed in the block 13e, and a gear 13f (miter gear) is fixed to the leading end. The shaft 13c is a pipe-shaped shaft. A solid material may be used, but a hollow material (pipe shape) is preferable in terms of weight. One end of the pipe cover 13d is fixed to the block 13e by welding or the like, and supports the shaft 13c while maintaining a minute gap with the shaft 13c. The block 13e has shaft holes that intersect at right angles. The shaft 13c is inserted into one shaft hole, and the shaft 13g is inserted into the other shaft hole. The shaft 13g is disposed at a right angle to the shaft 13c by being inserted into the shaft hole of the block 13e. On the side of the gear 13f, a gear 13h (miter gear) arranged so that the direction of rotation of the shaft 13c can be changed by 90 degrees is fixed so as to mesh with the gear 13f. In addition, a socket 13i into which a nut 12 with a disc spring can be inserted and fixed is provided at the tip opposite to the end to which the gear 13h is attached.
(2) The socket 13i holds the nut 12 with a disc spring semi-fixed to the magnetic force or the spring force. “Semi-fixedly hold” means that when the socket 13i holds the nut 12 with a disc spring, the nut 12 with a disc spring is prevented from dropping from the socket 13i due to gravity. Means that the nut 12 with a disc spring is held from the socket 13i in a state where it can be taken out.
(3) Further, when the hexagonal bar 13b is rotated with a ratchet wrench or the like when the front wall 8-1 and the side wall 7-1 are fastened, the anti-rotation member 13j (handle mounting portion) is used as an anti-rotation of the main body. Prevents the wall panel fastening tool 13 itself from rotating in the torque direction applied from the ratchet wrench by inserting a handle such as a spanner.

図７は、壁パネル締結工具１３によって皿バネ付きナット１２を雄ネジ部１０ａにねじ込む場合を説明する図である。図７（ａ）は、ソケット１３ｉが皿バネ付きナット１２を受ける様子を示している。図７（ｂ）は、ソケット１３ｉによって半固定的に保持される皿バネ付きナット１２を雄ネジ部１０ａにねじ込む場合を説明する図である。皿バネ付きナット１２を雄ネジ部１０ａにねじ込む場合、皿バネ付きナット１２は、六角ナット部の最大幅ｂ２よりも皿バネ部の外径Ｂ１のほうが大きい。このため、皿バネ付きナット１２は、皿バネのない通常のナットに比べて、雄ネジ部１０ａの先端を探りやすい。このため、図１に示したように、天井に上がって締結作業する作業者にとっての負担が軽減する。実施の形態１ではナットとして皿バネ付きナット１２を示したが、六角ナット部の最大幅ｂ２よりも外径Ｂ１のほうが大きいフランジ、ワッシャなどを有するフランジ付きナット、ワッシャ付きナットなどを用いても構わない。 FIG. 7 is a view for explaining a case where the disc spring-loaded nut 12 is screwed into the male screw portion 10a by the wall panel fastening tool 13. As shown in FIG. FIG. 7A shows how the socket 13i receives the nut 12 with a disc spring. FIG. 7B is a diagram for explaining a case where the nut 12 with a disc spring held semi-fixed by the socket 13i is screwed into the male screw portion 10a. When the nut 12 with a disc spring is screwed into the male screw portion 10a, the nut 12 with a disc spring has a larger outer diameter B1 of the disc spring portion than the maximum width b2 of the hexagon nut portion. For this reason, the nut 12 with a disc spring is easier to find the tip of the male screw portion 10a than a normal nut without a disc spring. For this reason, as shown in FIG. 1, the burden on the worker who goes up to the ceiling and performs the fastening work is reduced. In Embodiment 1, the nut 12 with a disc spring is shown as a nut. However, a flange with a larger outer diameter B1 than the maximum width b2 of the hexagonal nut portion, a nut with a flange having a washer, a nut with a washer, or the like may be used. I do not care.

図８は、図４の締結部の詳細を示す図である。図８（ａ）〜（ｃ）は、図４（ｂ）の断面Ｂ−Ｂ位置を示している。図８（ｂ）は、図８（ａ）に対して、側面壁７−１の貫通穴７ｈを雄ネジ部１０ａに差し込んだ状態を示す。図８（ｃ）は、図８（ａ）に対して、貫通穴７ｈから出ている雄ネジ部１０ａに皿バネ付きナット１２をねじ込み締結した状態を示している。 FIG. 8 is a diagram showing details of the fastening portion of FIG. 8A to 8C show the position of the cross section BB in FIG. 4B. FIG. 8B shows a state in which the through hole 7h of the side wall 7-1 is inserted into the male screw portion 10a with respect to FIG. 8A. FIG. 8 (c) shows a state in which a nut 12 with a disc spring is screwed and fastened to the male screw portion 10a protruding from the through hole 7h as compared with FIG. 8 (a).

実施の形態２．
図９を参照して実施の形態２を説明する。図９は、実施の形態１の図８に対する。実施の形態１では、雄ネジ部として、ボルト１０が溶接された固定金具９を正面壁８−１に接着材などを用いて固着していた。すなわち、雄ネジ部は、ボルト１０を固定金具に溶接することで実現していた。これに対して実施の形態２では、固定金具に溶接等により固着された袋ナットに対して、棒ネジ１１をねじ込むことにより雄ネジロッド部を実現する実施形態である。すなわち、
「ボルト１０＝袋ナット１５＋棒ネジ１１」
と置換されたものである。したがって、ボルト１０以外の固定金具の形状やその他の部品は実施の形態１と同じである。 Embodiment 2. FIG.
The second embodiment will be described with reference to FIG. FIG. 9 corresponds to FIG. 8 of the first embodiment. In the first embodiment, as the male screw portion, the fixing bracket 9 to which the bolt 10 is welded is fixed to the front wall 8-1 using an adhesive or the like. That is, the male screw portion has been realized by welding the bolt 10 to the fixing bracket. On the other hand, Embodiment 2 is an embodiment in which a male screw rod portion is realized by screwing a rod screw 11 into a cap nut fixed to a fixing bracket by welding or the like. That is,
"Bolt 10 = cap nut 15 + bar screw 11"
Is replaced. Therefore, the shape of the fixture other than the bolt 10 and other parts are the same as those in the first embodiment.

図９は、棒ネジ１１を用いる場合の壁パネルの締結方法を示す図である。図９を参照して実施の形態２における壁パネルの締結方法を説明する。 FIG. 9 is a diagram illustrating a method of fastening the wall panel when the bar screw 11 is used. With reference to FIG. 9, the fastening method of the wall panel in Embodiment 2 is demonstrated.

固定金具１４は、締結用の袋ナット１５が溶接等により固定されているＬ字型の固定金具である。実施の形態１の固定金具９と同じく、固定金具１４は接着材等により、正面壁８に固定される。図４の場合と同じく、固定金具１４は、正面壁８−１に複数（５箇所程度）取り付けられている。 The fixing bracket 14 is an L-shaped fixing bracket in which a fastening cap nut 15 is fixed by welding or the like. As with the fixing bracket 9 of the first embodiment, the fixing bracket 14 is fixed to the front wall 8 with an adhesive or the like. As in the case of FIG. 4, a plurality (about five places) of the fixtures 14 are attached to the front wall 8-1.

棒ネジ１１は、固定金具１４に固定されている袋ナット１５に挿入するものであり、ほぼ全長にネジ溝が施工されている。 The bar screw 11 is inserted into the cap nut 15 fixed to the fixing bracket 14, and a screw groove is provided in almost the entire length.

図９を参照して壁パネルの組立順序（ａ）〜（ｆ）を説明する。
（１）図９（ａ）〜（ｃ）に示すように、
まず袋ナット１５を有する固定金具１４が取り付けられている正面壁８−１の袋ナット１５に、棒ネジ１１を挿入して締め付ける。棒ネジ１１は挿入部先端が袋ナット１５の袋部に接する為、後にナット側を締め付けても共回りはしない。なお、棒ネジの取り付けは、壁パネルの据え付けにおいてネックとなる工程ではなく、エレベータ乗場などで取り付けてもよい。
（２）次に、図９（ｄ）、（ｅ）に示すように、側面壁７−１（実施の形態１と同じく、側面壁７には棒ネジ１１の挿入するネジ用穴が施工されている）を正面壁８−１の棒ネジ１１に沿って（図４の場合と同様に棒ネジ１１は上下方向に５本並んでいる）正面壁８−１の意匠面８ａと側面壁７−１の端部面７ａ（平面部）を当てるように配置する。
（３）次に、壁パネル締結工具１３の先端ソケット１３ｉに皿バネ付きナット１２を挿入する。
（４）次に、壁パネル締結工具１３の先端ソケット１３ｉを棒ネジ１１の端部前方にもっていき、壁パネル締結工具１３の取っ手１３ａの六角棒１３ｂをラチェット・レンチ等の工具で回転させ、皿バネ付きナット１２を締め付ける（図９（ｆ））。 The wall panel assembly sequence (a) to (f) will be described with reference to FIG.
(1) As shown in FIGS. 9A to 9C,
First, the bar screw 11 is inserted and tightened into the cap nut 15 of the front wall 8-1 to which the fixing metal fitting 14 having the cap nut 15 is attached. Since the end of the insertion portion of the bar screw 11 is in contact with the bag portion of the cap nut 15, it does not rotate together even if the nut side is tightened later. In addition, you may attach a bar screw not in the process used as a neck in the installation of a wall panel but in an elevator hall.
(2) Next, as shown in FIGS. 9D and 9E, the side wall 7-1 (similar to the first embodiment, the side wall 7 is provided with a screw hole into which the bar screw 11 is inserted. The design surface 8a and the side wall 7 of the front wall 8-1 are aligned along the bar screws 11 of the front wall 8-1 (same as in the case of FIG. 4, five bar screws 11 are arranged in the vertical direction). -1 end surface 7a (plane portion) is disposed.
(3) Next, the nut 12 with a disc spring is inserted into the tip socket 13 i of the wall panel fastening tool 13.
(4) Next, the tip socket 13i of the wall panel fastening tool 13 is moved forward of the end of the bar screw 11, and the hexagonal bar 13b of the handle 13a of the wall panel fastening tool 13 is rotated with a tool such as a ratchet wrench. The nut 12 with a disc spring is tightened (FIG. 9F).

以上の様に構成することで、かご室壁パネルを据え付ける際に、かご室と昇降路（昇降路機器）との間に作業スペースが無くても、かご室天井上からやかご床下側（ピット）から壁パネル締結作業が可能となる。 By constructing as described above, when installing the car room wall panel, even if there is no work space between the car room and the hoistway (hoistway equipment), the upper side of the car room under the car floor (pit) ) Enables wall panel fastening work.

なお、実施の形態１では固定金具にボルト１０を溶接等により固定し、実施の形態２では、固定金具に袋ナット１５を溶接等により固定して棒ネジ１１をねじ込む構成とした。これらは一例であり、例えば、図１０に示すように、正面壁８−１における雄ネジ部が突出する位置にボルトを溶接等により固着しても構わない。但し、正面壁８−１にボルト１０を直接溶接等で固着する方式は、固定金具にボルト１０を溶接する場合に比べ作業性が劣ること、また、壁パネルの据え付け時に、突き出たボルト１０の雄ネジ部で作業者が怪我をすることも考えられることから、固定金具を用いる方が好ましい。 In the first embodiment, the bolt 10 is fixed to the fixing bracket by welding or the like, and in the second embodiment, the cap nut 15 is fixed to the fixing bracket by welding or the like and the bar screw 11 is screwed. These are examples, and for example, as shown in FIG. 10, bolts may be fixed by welding or the like at positions where the male screw portions of the front wall 8-1 protrude. However, the method of fixing the bolt 10 directly to the front wall 8-1 by welding or the like is inferior in workability compared to the case where the bolt 10 is welded to the fixing bracket, and the protruding bolt 10 is not installed when the wall panel is installed. Since it is conceivable that the worker may be injured at the male screw portion, it is preferable to use a fixing bracket.
