しかしながら、上記特許文献１に示されたような制御盤を機械室壁に固定する方法の場合、機械室壁が石膏パネル等の強度が低いものであった場合は、地震等の倒れ防止性能が確保できず、制御盤の取付固定構造には使えない。
また、上記特許文献２に示されたような既設の制御盤を用いて固定する方法の場合、そもそも既設の制御盤に転倒防止策が施されていない場合には用いることができず、また、既設と新設の双方の制御盤を機械室に配置しなければならず、機械室のレイアウト上の制約が大きい。However, in the case of the method of fixing the control panel to the machine room wall as shown in Patent Document 1, if the machine room wall has a low strength such as a gypsum panel, the fall prevention performance such as an earthquake is not possible. It cannot be secured and cannot be used for the control panel mounting and fixing structure.
Moreover, in the case of the method of fixing using the existing control panel as shown in the above-mentioned Patent Document 2, it cannot be used if the existing control panel is not provided with a tipping prevention measure. Both the existing and new control panels must be placed in the machine room, and there are significant restrictions on the layout of the machine room.

実施の形態１．
図４はこの発明による制御盤の取付固定構造および取付固定方法が適用されるエレベーターの全体構造の概略図である。昇降路１００では、かご１０１と釣合錘１０２が主索１０６の両端にそれぞれ取り付けられ吊るされている。主索１０６は巻上機１０３とそらせ車１０５に掛けられている。そして巻上機１０３が回転することで、主索１０６が動き、かご１０１と釣合錘１０２が昇りと降りの互いに反対の方向に移動させられる。巻上機１０３と、この巻上機１０３の駆動制御を含む行うエレベーターの制御を行う制御盤１０４は、昇降路１００最上部の機械室１１０の機械室床面１１０ａ上に設けられている。Embodiment 1 FIG.
FIG. 4 is a schematic view of the overall structure of an elevator to which the control panel mounting and fixing structure and the mounting and fixing method according to the present invention are applied. In the hoistway 100, a car 101 and a counterweight 102 are attached to and suspended from both ends of the main rope 106, respectively. The main rope 106 is hung on the hoisting machine 103 and the deflecting wheel 105. When the hoisting machine 103 rotates, the main rope 106 moves, and the car 101 and the counterweight 102 are moved in the opposite directions of ascending and descending. The hoisting machine 103 and the control panel 104 for controlling the elevator including the driving control of the hoisting machine 103 are provided on the machine room floor surface 110 a of the machine room 110 at the uppermost part of the hoistway 100.

図１は、この発明による制御盤の取付固定構造および取付固定方法により制御盤１０４が取付固定される前の、機械室１１０の巻上機１０３付近の状態を示す部分拡大図である。機械室床面１１０ａには、主索１０６を機械室１１０から昇降路１００に導く開口部１１０ｂが設けられている。開口部１１０ｂの両側には例えばＨ形鋼からなる機械台１が互いに平行になるようにそれぞれ設けられている。巻上機１０３はこれらの機械台１上に、これらを跨ぐようにして固定されている。機械台１上の巻上機１０３が搭載されている部分以外は、上部に何も配置されていない状態である。また各機械台１は、エレベーターの昇降路１００の枠構造を構成する強固な構造梁(図示省略)上に、例えば溶接等で固定されている。   FIG. 1 is a partially enlarged view showing a state in the vicinity of the hoisting machine 103 in the machine room 110 before the control panel 104 is mounted and fixed by the control panel mounting and fixing structure and the mounting and fixing method according to the present invention. The machine room floor 110a is provided with an opening 110b for guiding the main rope 106 from the machine room 110 to the hoistway 100. Machine tables 1 made of, for example, H-shaped steel are provided on both sides of the opening 110b so as to be parallel to each other. The hoisting machine 103 is fixed on these machine tables 1 so as to straddle them. Except for the part on which the hoisting machine 103 is mounted on the machine base 1, nothing is arranged at the top. Each machine base 1 is fixed by, for example, welding or the like on a rigid structural beam (not shown) constituting the frame structure of the elevator hoistway 100.

図２は、この発明による制御盤の取付固定構造および取付固定方法により制御盤１０４が取付固定された後の、機械室１１０の巻上機１０３付近の状態を示す部分拡大図である。制御盤取付梁２が各機械台１に直交または略直交するように配置される。そして制御盤取付梁２は、２本の機械台１の両方または片方の上に第１の固定部３ａを構成するボルトとナット(後述する図３参照)でボルト締結されて固定される。この場合、例えば、移動可能な制御盤取付梁２にはボルトを貫通させる貫通穴を予め形成しておく。そして現場すなわち機械室１１０において、最初に移動不可の機械台１に穴あけ加工を施してボルトを貫通させる貫通穴を形成し、その後、機械台１に対して制御盤取付梁２をボルト締結する。
なおこの第１の固定部３ａとして、図５に一例を示すように、ボルトとナットでクリップ部材３ｃを締め付けることにより、制御盤取付梁２をクリップ部材３ｃと機械台１の間に挟み込んで押え付けて固定するレールクリップを使用してもよい。FIG. 2 is a partial enlarged view showing a state in the vicinity of the hoisting machine 103 in the machine room 110 after the control panel 104 is mounted and fixed by the control panel mounting and fixing structure and the mounting and fixing method according to the present invention. The control panel mounting beam 2 is arranged so as to be orthogonal or substantially orthogonal to each machine base 1. The control panel mounting beam 2 is fixed by being bolted to both or one of the two machine bases 1 with bolts and nuts (see FIG. 3 described later) constituting the first fixing portion 3a. In this case, for example, a through hole through which the bolt is passed is formed in advance in the movable control panel mounting beam 2. Then, at the site, that is, in the machine room 110, the machine base 1 that is not movable is first drilled to form a through-hole through which the bolt passes, and then the control panel mounting beam 2 is bolted to the machine base 1.
As an example of this first fixing portion 3a, as shown in FIG. 5, the clip member 3c is tightened with a bolt and a nut so that the control panel mounting beam 2 is sandwiched between the clip member 3c and the machine base 1 and pressed. Rail clips that are attached and fixed may be used.

そしてさらに、制御盤取付梁２の一方の端面に制御盤１０４の側面が、第２の固定部３ｂを構成するボルトとナット(後述する図３参照)でボルト締結されて固定される。この場合、例えば、移動可能な制御盤取付梁２および制御盤１０４にはボルトを貫通させる貫通穴を予め形成しておく。そして現場すなわち機械室１１０において、制御盤取付梁２に対して制御盤１０４をボルト締結する。制御盤１０４は機械室床面１１０ａには固定されていない。
なお、移動可能な制御盤取付梁２および制御盤１０４の貫通穴の形成も、現場すなわち機械室１１０において行ってもよい。
また、制御盤１０４がいずれかの側面に開閉扉等を有する場合、開閉扉のある面を前面とした場合、反対側の背面で固定するようにしてもよい。Further, the side surface of the control panel 104 is fixed to one end face of the control panel mounting beam 2 by bolting and fastening with bolts and nuts (see FIG. 3 described later) constituting the second fixing portion 3b. In this case, for example, the movable control panel mounting beam 2 and the control panel 104 are previously formed with through holes through which the bolts pass. Then, the control panel 104 is bolted to the control panel mounting beam 2 at the site, that is, the machine room 110. The control panel 104 is not fixed to the machine room floor 110a.
The movable control panel mounting beam 2 and the through hole of the control panel 104 may be formed in the field, that is, the machine room 110.
Further, when the control panel 104 has an opening / closing door or the like on any side surface, when the surface with the opening / closing door is a front surface, the control panel 104 may be fixed on the back surface on the opposite side.

また機械台１は、Ｈ形鋼に限らず、溝形鋼やその他の形状であっても同様の方法で対応可能である。また機械台１は、３本以上が平行に設けられた構造のものであってもよい。この場合、制御盤取付梁２は、１本または複数本の機械台１に、機械台１に直交または略直交するように固定される。
なお、機械台１同士は必ず並行または略並行である必要はなく、また制御盤取付梁２も機械台１に対して直交または略直交するように配置される必要もない。Further, the machine base 1 is not limited to the H-section steel, and can be handled in the same manner even if it is a groove-shaped steel or other shapes. Further, the machine base 1 may have a structure in which three or more are provided in parallel. In this case, the control panel mounting beam 2 is fixed to one or a plurality of machine tables 1 so as to be orthogonal or substantially orthogonal to the machine table 1.
Note that the machine bases 1 do not necessarily have to be parallel or substantially parallel to each other, and the control panel mounting beam 2 does not have to be arranged to be orthogonal or substantially orthogonal to the machine base 1.

また、図３のごとく、新規の制御盤１０４を、制御盤１０４の重心位置Ｇの高さで制御盤取付梁２と固定することで、地震時に制御盤１０４に曲げモーメントを発生させることなく固定が可能となる。
なお、制御盤取付梁２と制御盤１０４との締結位置が、制御盤１０４の重心位置Ｇの高さであることが重要である。例えば、機械台１の高さに比べ、制御盤１０４の重心位置Ｇが高い位置にあるのであれば、制御盤取付梁２の制御盤１０４と締結する面の高さＨが、重心位置Ｇの高さと同じまたはそれ以上の高さになる構造となる。制御盤取付梁２の剛性を上げることで、地震時のモーメントは制御盤取付梁２で支えることができるため、制御盤１０４自体には影響がでない。Further, as shown in FIG. 3, the new control panel 104 is fixed to the control panel mounting beam 2 at the height of the center of gravity G of the control panel 104, so that the control panel 104 can be fixed without generating a bending moment in the event of an earthquake. Is possible.
It is important that the fastening position between the control panel mounting beam 2 and the control panel 104 is the height of the gravity center position G of the control panel 104. For example, if the center of gravity G of the control panel 104 is higher than the height of the machine base 1, the height H of the surface to be fastened with the control panel 104 of the control panel mounting beam 2 is equal to the center of gravity G. The structure becomes the height equal to or higher than the height. By increasing the rigidity of the control panel mounting beam 2, the moment at the time of an earthquake can be supported by the control panel mounting beam 2, so that the control panel 104 itself is not affected.
