既設乗客コンベアの既設本体枠を利用して新設乗客コンベアを設置する乗客コンベア設備は、例えば特許文献１に開示されているように、既に提案されている。 A passenger conveyor facility that installs a new passenger conveyor using an existing main body frame of an existing passenger conveyor has already been proposed as disclosed in, for example, Patent Document 1.

特公平３−４８１１５号公報Japanese Patent Publication No. 3-48115

前記従来の技術は、既設乗客コンベアの構成部品を撤去した既設本体枠を利用して新設乗客コンベアの新設本体枠を支持し、この新設本体枠内に新設乗客コンベアの構成部品を実装させるものであるが、既設本体枠の支持部に新設本体枠を係合させた場合、既設本体枠の支持部表面が酸化されている等、新設本体枠の支持部表面と表面状態が異なる場合、そこに局部電池が形成されて電位差腐食が発生する可能性がある。 The conventional technology supports the new main body frame of the new passenger conveyor by using the existing main body frame from which the existing passenger conveyor components are removed, and mounts the new passenger conveyor components in the new main body frame. However, if the new main body frame is engaged with the support part of the existing main body frame, the surface of the support part of the existing main body frame is oxidized, etc. A local battery may be formed and potentiometric corrosion may occur.

特に、建築構造物の梁に支持される既設本体枠の受梁と、この受梁に支持される新設本体枠の受梁間に電位差腐食が生じた場合、新設乗客コンベアを含めた全重量を支持する既設本体枠の受梁の腐食を早めて強度を低下させることになり、最悪の場合、乗客コンベア設備が沈み込む事態が生じる虞がある。 In particular, when potential difference corrosion occurs between the receiving beam of the existing main frame supported by the beam of the building structure and the receiving beam of the new main frame supported by the receiving beam, the entire weight including the new passenger conveyor is supported. As a result, corrosion of the receiving beam of the existing main body frame is accelerated and the strength is lowered. In the worst case, there is a possibility that the passenger conveyor facility sinks.

本発明の目的は、既設乗客コンベアの既設本体枠を利用して新設乗客コンベアを設置しても安定した新設乗客コンベアの支持が行える乗客コンベア設備を提供することにある。 An object of the present invention is to provide a passenger conveyor facility that can stably support a new passenger conveyor even if a new passenger conveyor is installed using an existing main body frame of an existing passenger conveyor.

本発明は上記目的を達成するために、建築構造物に支持された既設本体枠と、この既設本体枠に新設の乗客コンベアの新設本体枠を支持する際、既設本体枠の支持部と新設本体枠の支持部間に電位差腐食防止手段を設けたのである。 In order to achieve the above object, the present invention provides an existing main body frame supported by a building structure, and a new main body frame supporting portion and a new main body when the new main body frame of a new passenger conveyor is supported on the existing main body frame. Potential difference corrosion prevention means is provided between the support portions of the frame.

このように、既設本体枠の支持部と新設本体枠の支持部間に電位差腐食防止手段を設けることで、既設本体枠の支持部と新設本体枠の支持部間に発生する電位差腐食を低減することができ、安定した新設乗客コンベアの支持を行うことができる。 Thus, by providing a potential difference corrosion prevention means between the support portion of the existing main body frame and the support portion of the new main body frame, the potential difference corrosion generated between the support portion of the existing main body frame and the support portion of the new main body frame is reduced. It is possible to support a stable new passenger conveyor.

以上説明したように本発明によれば、既設乗客コンベアの既設本体枠を利用して新設乗客コンベアを設置しても安定した新設乗客コンベアの支持が行える乗客コンベア設備を得ることができる。 As described above, according to the present invention, it is possible to obtain passenger conveyor equipment that can stably support a new passenger conveyor even if the new passenger conveyor is installed using the existing main body frame of the existing passenger conveyor.

以下本発明による乗客コンベア設備の一実施の形態を図１〜図４に示すエスカレーター設備に基づいて説明する。 An embodiment of passenger conveyor equipment according to the present invention will be described below based on the escalator equipment shown in FIGS.

エスカレーター設備１は、既設のエスカレーターの構成部品が撤去された既設本体枠２と、この既設本体枠２に支持された新設エスカレーター３とから構成されている。 The escalator facility 1 includes an existing body frame 2 from which components of an existing escalator have been removed, and a new escalator 3 supported by the existing body frame 2.

既設本体枠２は、左右に間隔をあけて配置された側枠４Ａ，４Ｂと、これら左右の側枠４Ａ，４Ｂを底部において機械的に連結する底板５と、左右の側枠４Ａ，４Ｂの長手方向端部に設けた端枠６Ａ，６Ｂとを備えており、端枠６Ａ，６Ｂには夫々受梁７Ａ，７Ｂが水平に枠外に突出して設けられている。そして、既設本体枠２の受梁７Ａ，７Ｂを、建築構造物８の離れた建築梁９，９間に跨るように係合させている。 The existing main body frame 2 includes side frames 4A and 4B that are arranged at intervals on the left and right sides, a bottom plate 5 that mechanically connects the left and right side frames 4A and 4B at the bottom, and left and right side frames 4A and 4B. End frames 6A and 6B provided at the ends in the longitudinal direction are provided, and receiving beams 7A and 7B are horizontally provided on the end frames 6A and 6B so as to protrude from the frame. And the receiving beams 7A and 7B of the existing main body frame 2 are engaged so as to straddle between the building beams 9 and 9 apart from the building structure 8.

一方、新設エスカレーター３は、新設本体枠１０をベースに構成されており、この新設本体枠１０も、既設本体枠２と同じように、左右に間隔をあけて配置された側枠１１Ａ，１１Ｂと、これら側枠１１Ａ，１１Ｂの長手方向端部に設けた端枠１２Ａ，１２Ｂとを備えており、端枠１２Ａ，１２Ｂには夫々受梁１３Ａ，１３Ｂが水平に枠外に突出して設けられている。このように構成された新設本体枠１０には、無端状に連結された複数の踏段１６，欄干１７，欄干１７の周縁を循環移動する移動手摺１８，乗降床１９，踏段１６や移動手摺１８を駆動する駆動機構，運転を制御する制御装置，安全装置等の新設エスカレーター３として必要な構成部品が実装される。これら構成部品の実装時期は、新設本体枠１０の既設本体枠２への組み込みタイミングで決められるので、既設本体枠２への組み込み時に新設本体枠１０に実装されているものや、既設本体枠２への新設本体枠１０の組み込み後に実装されるものもある。 On the other hand, the new escalator 3 is configured based on the new main body frame 10, and the new main body frame 10 also has side frames 11 </ b> A and 11 </ b> B arranged at intervals on the left and right, like the existing main body frame 2. The end frames 12A and 12B are provided at the longitudinal ends of the side frames 11A and 11B. The end frames 12A and 12B are respectively provided with receiving beams 13A and 13B that protrude horizontally outside the frame. . The new main body frame 10 configured in this way includes a plurality of steps 16 connected endlessly, a balustrade 17, a moving handrail 18 that circulates and moves around the periphery of the balustrade 17, a landing floor 19, a step 16, and a moving handrail 18. Components necessary for the newly installed escalator 3, such as a drive mechanism for driving, a control device for controlling operation, and a safety device, are mounted. The mounting timing of these components is determined by the timing of incorporation of the new main body frame 10 into the existing main body frame 2, so that the component body is mounted on the new main body frame 10 when installed in the existing main body frame 2 or the existing main body frame 2. Some are installed after the installation of the newly installed main body frame 10.

上記新設本体枠１０を既設本体枠２に支持させる場合、新設本体枠１０の支持部である受梁１３Ａ，１３Ｂを既設本体枠２の支持部である受梁７Ａ，７Ｂ上に係合させて新設エスカレーター３の全荷重を支持させる。尚、建築構造物８の建築梁９，９間が長い場合には、既設本体枠２及び新設本体枠１０の長手方向中間部の側枠４Ａ，４Ｂ，１１Ａ，１１Ｂから互いに接近するように支持部である支持ブラケット１４Ａ，１４Ｂ，１５Ａ，１５Ｂを突出させて係合する。 When the existing main body frame 10 is supported by the existing main body frame 2, the receiving beams 13A and 13B that are the support portions of the new main body frame 10 are engaged with the receiving beams 7A and 7B that are the support portions of the existing main body frame 2. Support the full load of the newly established escalator 3. In addition, when the space between the building beams 9 and 9 of the building structure 8 is long, it supports so that it may mutually approach from the side frames 4A, 4B, 11A, and 11B of the longitudinal direction intermediate part of the existing main body frame 2 and the new main body frame 10 The support brackets 14A, 14B, 15A, and 15B, which are parts, are projected and engaged.

これら受梁７Ａ，７Ｂ上への受梁１３Ａ，１３Ｂの係合又は／及び支持ブラケット１４Ａ，１４Ｂ上への支持ブラケット１５Ａ，１５Ｂの係合に際し、両者間に電位差腐食防止手段を形成するために、夫々電気絶縁体である例えば合成ゴムのような電気絶縁ゴム材２０，２１を介在させている。 When engaging the receiving beams 13A and 13B on the receiving beams 7A and 7B and / or engaging the supporting brackets 15A and 15B on the supporting brackets 14A and 14B, in order to form a potential difference corrosion preventing means between them. Further, electric insulating rubber materials 20 and 21 such as synthetic rubber, which are electric insulators, are interposed.

このように、電気絶縁ゴム材２０，２１を受梁７Ａ，７Ｂと受梁１３Ａ，１３Ｂ間又は／及び支持ブラケット１４Ａ，１４Ｂと支持ブラケット１５Ａ，１５Ｂ間に介在させることで、これらの間に電位差が生じたとしても電気的に絶縁されているので、電位差腐食は発生しない。その結果、既設本体枠２の受梁７Ａ，７Ｂの腐食の進行をなくし、長期に亘って新設本体枠１０を安定して支持することができる。 Thus, by interposing the electrical insulating rubber materials 20 and 21 between the receiving beams 7A and 7B and the receiving beams 13A and 13B and / or between the support brackets 14A and 14B and the support brackets 15A and 15B, a potential difference therebetween. Even if this occurs, since it is electrically insulated, potentiometric corrosion does not occur. As a result, the progress of corrosion of the receiving beams 7A and 7B of the existing main body frame 2 can be eliminated, and the new main body frame 10 can be stably supported over a long period of time.

ところで、上記実施の形態においては、電位差腐食防止手段として電気絶縁材である電気絶縁ゴム材２０，２１を介在させたが、これら電気絶縁ゴム材２０，２１を介在させる構成に限定されるものではなく、既設本体枠２や新設本体枠１０の大きさや形状さらには周囲環境等により、他の手段を講じることができる。 By the way, in the said embodiment, although the electrical insulation rubber materials 20 and 21 which are electrical insulation materials were interposed as a potential difference corrosion prevention means, it is not limited to the structure which these electrical insulation rubber materials 20 and 21 are interposed. In addition, other means can be taken depending on the size and shape of the existing main body frame 2 and the new main body frame 10 and the surrounding environment.

即ち、既設本体枠２に対し新設本体枠１０を強固に固定する場合には、受梁７Ａ，７Ｂと受梁１３Ａ，１３Ｂ間又は／及び支持ブラケット１４Ａ，１４Ｂと支持ブラケット１５Ａ，１５Ｂ間を絶縁ボルトや絶縁ナット等の絶縁締結具で締結することで、両者間の電位差腐食を防止することができる。また、新設エスイカレーター３が小型軽量な場合には、受梁７Ａ，７Ｂと受梁１３Ａ，１３Ｂ又は／及び支持ブラケット１４Ａ，１４Ｂと支持ブラケット１５Ａ，１５Ｂの対向面に絶縁性塗料を塗布して絶縁性塗膜を形成することで電位差腐食を防止することができ、加えて電気絶縁ゴム材を介在させることで、電位差腐食をより確実に防止することができる。さらに、受梁７Ａ，７Ｂと受梁１３Ａ，１３Ｂ間又は／及び支持ブラケット１４Ａ，１４Ｂと支持ブラケット１５Ａ，１５Ｂ間に電位差が発生しても両者の接触面を電流が流れないように、両者間を溶接して固定したり、電気的に接続して積極的に電流通路を形成したりすることで電位差腐食を防止することができる。この外、受梁７Ａ，７Ｂと受梁１３Ａ，１３Ｂ間又は／及び支持ブラケット１４Ａ，１４Ｂと支持ブラケット１５Ａ，１５Ｂ間の電位差を段階的に小さくして電位差腐食の発生を抑制するために、例えば、受梁７Ａ，７Ｂと受梁１３Ａ，１３Ｂ間に、両者の電位差の中間となる導電材を介在させるようにしてもよい。さらにまた、上記各手段を適宜組合せることで、電位差腐食防止効果を高めることができる。 That is, when the new main body frame 10 is firmly fixed to the existing main body frame 2, the receiving beams 7A and 7B and the receiving beams 13A and 13B or / and the support brackets 14A and 14B and the support brackets 15A and 15B are insulated. By fastening with an insulation fastener such as a bolt or an insulation nut, potential difference corrosion between them can be prevented. When the newly established escalator 3 is small and light, an insulating paint is applied to the opposing surfaces of the receiving beams 7A and 7B and the receiving beams 13A and 13B or / and the support brackets 14A and 14B and the support brackets 15A and 15B. By forming an insulating coating film, it is possible to prevent potential difference corrosion. In addition, by interposing an electrically insulating rubber material, potential difference corrosion can be more reliably prevented. Further, even if a potential difference occurs between the receiving beams 7A and 7B and the receiving beams 13A and 13B or / and between the support brackets 14A and 14B and the support brackets 15A and 15B, the current flows between the two. Is welded and fixed, or is electrically connected to actively form a current path, thereby preventing potential difference corrosion. In addition to this, in order to reduce the potential difference between the receiving beams 7A and 7B and the receiving beams 13A and 13B or / and between the support brackets 14A and 14B and the support brackets 15A and 15B in a stepwise manner, Alternatively, a conductive material that is in the middle of the potential difference between the receiving beams 7A and 7B and the receiving beams 13A and 13B may be interposed. Furthermore, the potential difference corrosion prevention effect can be enhanced by appropriately combining the above means.

以上説明したように、本実施の形態によれば、既設本体枠の支持部と新設本体枠の支持部間に電位差腐食防止手段を設けることで、これら支持部の腐食を防止することができる。 As described above, according to the present embodiment, the potential difference corrosion preventing means is provided between the support portion of the existing main body frame and the support portion of the new main body frame, whereby corrosion of these support portions can be prevented.

尚、上記実施の形態は、乗客コンベアとしてエスカレーターを一例に説明したが、隣接踏板間に段差を有しない電動道路にも適用することができる。 In addition, although the said embodiment demonstrated the escalator as an example as a passenger conveyor, it can be applied also to the electric road which does not have a level | step difference between adjacent treads.
