Description
本発明は、乗客コンベアに関する。 The present invention relates to a passenger conveyor.
エスカレータや動く歩道などに代表される乗客コンベアにあって、老朽化した既設の乗客コンベアを撤去し、同じ場所に新設の乗客コンベアを設置することで乗客コンベアのリニューアルが行われることがある。このようなリニューアルを行う際、既設の乗客コンベアの本体枠、すなわち既設本体枠を撤去せずに残し、既設本体枠内に新設の乗客コンベアの新設本体枠を配置する工法として、例えば特開２０１３−６７４６１号公報（特許文献１）や、国際出願ＰＣＴ／ＪＰ２０１３／０７４４５９号（特許文献２）に記載されたものがある。 In passenger conveyors typified by escalators and moving walkways, the old passenger conveyors that have become aged are removed, and new passenger conveyors are installed at the same location to renew the passenger conveyors. When performing such a renewal, for example, as a method of placing a new main body frame of a new passenger conveyor in an existing main body frame while leaving the main body frame of an existing passenger conveyor, that is, leaving the existing main body frame without removing it, for example, -67461 (patent document 1) and international application PCT / JP2013 / 07459 (patent document 2).
しかしながら、前述した特許文献１に記載のものでは、この文献の図２に示すように、新設本体枠の長手方向端部に設けられる新設受梁は、建屋梁に乗せられた既設本体枠の既設受梁の上部にさらに乗せられた状態で固定されており、建屋梁に対する新設受梁の掛かり代は、建屋梁に対する既設受梁の掛かり代と同じに設定されている。 However, in the thing of the patent document 1 mentioned above, as shown in FIG. 2 of this literature, the new receiving beam provided in the longitudinal direction edge part of a new main body frame is the existing installation of the existing main body frame carried on the building beam. It is fixed in a state where it is further placed on the upper part of the receiving beam, and the hanging amount of the new receiving beam with respect to the building beam is set to be the same as that of the existing receiving beam with respect to the building beam.
ここで、近年、地震動や各種振動により建築構造体内において発生する層間変位に対応するための耐震性の要求が高くなっている。既設本体枠内に新設本体枠を単に設置した場合、新設本体枠の耐震性は既設本体枠の耐震性を反映するのみであることから、現在の要求を満たすことができないという課題がある。特に、層間変位等により建屋梁間の距離が広がった場合に、本体枠が建屋梁から脱落することを防ぐ点で高い基準が求められるようになっている。 Here, in recent years, there has been a growing demand for earthquake resistance to cope with interlayer displacements that occur in a building structure due to earthquake motion and various vibrations. When a new main body frame is simply installed in an existing main body frame, the earthquake resistance of the new main body frame only reflects the earthquake resistance of the existing main body frame. In particular, when the distance between building beams increases due to interlayer displacement or the like, a high standard is required in terms of preventing the main body frame from falling off the building beams.
したがって、特許文献１に記載のものでは、建屋梁間の距離が広がって既設本体枠が落下した場合、新設本体枠も一緒に落下してしまうという問題がある。 Therefore, in the thing of patent document 1, when the distance between building beams spreads and the existing main body frame falls, there exists a problem that a new main body frame will also fall together.
そこで、出願人は、特許文献２において、建屋梁に対する新設受梁の掛かり代を建屋梁に対する既設受梁の掛かり代よりも大きく設定するとともに、新設本体枠と既設本体枠とを連結し既設受梁が建屋梁から外れた場合に既設本体枠の落下を防止する連結部材を設ける技術を出願している。 Therefore, in Patent Document 2, the applicant sets the hanging allowance of the new receiving beam for the building beam to be larger than the hanging allowance of the existing receiving beam for the building beam, and connects the existing main frame to the existing main frame. A technology for providing a connecting member for preventing the existing main body frame from falling when the beam is detached from the building beam has been filed.
しかしながら、特許文献２の場合、既設本体枠、新設本体枠、連結部材の寸法精度や組み立て精度の問題から、新設本体枠または既設本体枠と連結部材との間に隙間ができてしまう可能性があり、この隙間をなくすことは困難である。また、この隙間がある場合には、既設受梁が建屋梁から外れた場合に、隙間分の落下による衝撃が発生するという問題がある。 However, in the case of Patent Document 2, there is a possibility that a gap may be formed between the new main body frame or the existing main body frame and the connecting member due to problems of dimensional accuracy and assembly accuracy of the existing main body frame, the new main body frame, and the connecting member. Yes, it is difficult to eliminate this gap. Further, in the case where there is a gap, there is a problem that when the existing receiving beam is detached from the building beam, an impact due to a drop corresponding to the gap occurs.
本発明は、前述した従来技術における実状からなされたもので、その目的は、リニューアルに際し、既設のものよりも落下しにくくして耐震性を増すことのできるとともに、新設本体枠と既設本体枠とを連結する連結部材との間の隙間をなくして隙間分の落下による衝撃を防止し、かつ、隙間をなくすための高さ調整が容易な乗客コンベアを提供することにある。 The present invention is made from the actual state in the above-described prior art, and the purpose of the present invention is to make it more difficult to drop than existing ones when renewing and to increase earthquake resistance, and to establish a new main body frame and an existing main body frame. It is an object of the present invention to provide a passenger conveyor that eliminates a gap between the connecting members connecting the two and prevents a shock due to a drop of the gap and that can be easily adjusted in height to eliminate the gap.
前記目的を達成するために、本発明は、例えば、既設の乗客コンベアの本体枠であって長手方向端部に建屋梁に掛けられる既設受梁が設けられた既設本体枠と、前記既設本体枠の内部に配置された新設の乗客コンベアの本体枠であって長手方向端部に前記建屋梁に掛けられる新設受梁が設けられた新設本体枠とを有する乗客コンベアにおいて、前記建屋梁に対する前記新設受梁の掛かり代は、前記建屋梁に対する前記既設受梁の掛かり代よりも大きく設定されており、前記新設本体枠と前記既設本体枠とを連結し、前記既設受梁が前記建屋梁から外れた場合に前記既設本体枠の落下を防止する連結部材を有し、前記既設受梁が前記建屋梁に掛けられた状態において、前記連結部材は、前記既設本体枠と前記新設本体枠とのうちの一方に固定されているとともに、他方には前記連結部材に設けられた高さ調整部品を介して隙間なく当接していることを特徴する。 In order to achieve the above object, the present invention provides, for example, an existing main body frame of an existing passenger conveyor provided with an existing receiving beam that is hung on a building beam at a longitudinal end, and the existing main body frame. A passenger frame having a body frame of a newly installed passenger conveyor disposed in the interior of the passenger conveyor and having a new body frame provided with a new receiving beam hung on the building beam at an end in a longitudinal direction thereof. A receiving allowance of the receiving beam is set to be larger than an existing allowance of the existing receiving beam with respect to the building beam, the new main body frame and the existing main body frame are connected, and the existing receiving beam is detached from the building beam. A connecting member that prevents the existing main body frame from dropping when the existing receiving beam is hung on the building beam, the connecting member includes the existing main body frame and the new main body frame. Fixed to one of the Together are, the other features that are in contact without any gap through the height adjusting member provided on the connecting member.
本発明によれば、新設受梁の掛かり代が既設受梁の掛かり代よりも大きいため既設のものよりも新設本体枠が落下しにくくなるとともに、既設受梁のみが建屋梁から外れた場合でも、連結部材によって既設本体枠の落下を防止することができ、かつ、新設本体枠または既設本体枠と連結部材との間は高さ調整部品を介して隙間なく当接しているので、隙間をなくすための高さ調整が容易にできるとともに既設受梁が建屋梁から外れた場合でも隙間分の落下による衝撃が発生するのを防止することができる。 According to the present invention, since the hanging allowance of the new receiving beam is larger than that of the existing receiving beam, the new body frame is less likely to drop than the existing one, and even when only the existing receiving beam is detached from the building beam. The connecting member can prevent the existing main body frame from dropping, and the new main body frame or the existing main body frame and the connecting member are in contact with each other through the height adjusting part, so that the gap is eliminated. Therefore, it is possible to easily adjust the height, and even when the existing receiving beam is detached from the building beam, it is possible to prevent the occurrence of an impact due to the fall of the gap.
本発明の実施例を、図面を参照しながら説明する。尚、各図において、同一又は類似の構成要素には同じ符号を付し、説明を省略する。 Embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or similar components are denoted by the same reference numerals and description thereof is omitted.
図１は、本発明に係る乗客コンベアの一実施例を示す全体構成図である。図２は、図１のＡ−Ａ線に沿う断面図である。本実施例の乗客コンベアは、例えばエスカレータであり、図１に示すように、リニューアルのために既設のエスカレータから構成部品を撤去した既設本体枠１は、既設下部水平部２と、既設上部水平部３と、既設傾斜部４とから構成されている。 FIG. 1 is an overall configuration diagram showing an embodiment of a passenger conveyor according to the present invention. 2 is a cross-sectional view taken along line AA in FIG. The passenger conveyor of the present embodiment is, for example, an escalator. As shown in FIG. 1, an existing main body frame 1 in which components are removed from an existing escalator for renewal includes an existing lower horizontal portion 2 and an existing upper horizontal portion. 3 and an existing inclined portion 4.
新設のエスカレータの本体枠である新設本体枠５は、図２にも示すように、既設本体枠１の収納空間に収納されるため、長手方向および短手方向において既設本体枠１よりも小型にできている。 As shown in FIG. 2, the new main body frame 5 which is a main body frame of the new escalator is stored in the storage space of the existing main body frame 1, so that it is smaller than the existing main body frame 1 in the longitudinal direction and the short side direction. is made of.
新設本体枠５は、既設本体枠１と同様に、新設下部水平部６と、新設上部水平部７と、新設傾斜部８とから構成されている。新設本体枠５には、無端状に連結され、乗降口間を循環移動する図示しないステップや、新設本体枠５の長手方向に沿いステップの両側に立設される欄干９や、欄干９の周縁に沿ってステップと同期して移動するハンドレール１０や、ステップやハンドレール１０を駆動する図示しない駆動装置などの各種の構成部品が装着される。なお、新設傾斜部８は、新設本体枠５の新設下部水平部６と新設上部水平部７との間の傾斜部分であり、新設傾斜部８の水平面に対する傾斜角度は、既設本体枠１における既設傾斜部４の傾斜角度と同じとなるように構成されている。 Similar to the existing main body frame 1, the new main body frame 5 includes a new lower horizontal portion 6, a new upper horizontal portion 7, and a new inclined portion 8. A step (not shown) connected endlessly to the new body frame 5 and circulating between the entrances and exits, a balustrade 9 erected on both sides of the step along the longitudinal direction of the new body frame 5, and the periphery of the balustrade 9 Various components such as a handrail 10 that moves in synchronization with the step and a driving device (not shown) that drives the step and the handrail 10 are mounted. The new inclined portion 8 is an inclined portion between the new lower horizontal portion 6 and the new upper horizontal portion 7 of the new main body frame 5, and the inclination angle of the new inclined portion 8 with respect to the horizontal plane is the same as that of the existing main body frame 1. The inclination angle of the inclined portion 4 is the same.
図３は、本実施例における受梁部分の要部拡大図である。既設本体枠１の長手方向端部、すなわち既設下部水平部２端部に設けられる既設受梁２ａは、図３に示すように、建屋梁１１上に高さ調整用の平板１２を介して相対移動可能に載置されている。そして、既設受梁２ａは、掛かり代Ｌ１を有して建屋梁１１に掛けられている。なお、既設本体枠１のもう一方の長手方向端部、すなわち既設上部水平部３端部に設けられる既設受梁３ａも同様の構成で建屋梁１３に掛けられている。但し、既設受梁３ａの方は、固定端とされ、既設受梁２ａとは異なり、相対移動できないように固定されている。 FIG. 3 is an enlarged view of a main part of the receiving beam portion in the present embodiment. As shown in FIG. 3, the existing receiving beam 2a provided at the end in the longitudinal direction of the existing main body frame 1, that is, at the end of the existing lower horizontal portion 2, is relative to the building beam 11 via a flat plate 12 for height adjustment. It is placed so that it can move. The existing receiving beam 2a is hung on the building beam 11 with a hanging allowance L1. In addition, the existing receiving beam 3a provided in the other longitudinal direction edge part of the existing main body frame 1, ie, the existing upper horizontal part 3, is also hung on the building beam 13 with the same configuration. However, the existing receiving beam 3a is a fixed end, and is fixed so that it cannot move relative to the existing receiving beam 2a.
新設本体枠５の長手方向端部、すなわち新設下部水平部６に設けられる新設受梁６ａは、図３に示すように、既設本体枠１の既設受梁２ａより大きい掛かり代Ｌ２を有するものとされ、高さ調整用のジャッキボルト１４、および高さ調整用の平板１５を介して建屋梁１１に相対移動可能に載置されている。なお、新設本体枠５のもう一方の長手方向端部、すなわち新設上部水平部７端部に設けられる新設受梁７ａも同様の構成で建屋梁１３に掛けられている。但し、新設受梁７ａの方は、固定端とされ、既設受梁６ａとは異なり、相対移動できないように固定されている。また、固定端の場合には、新設受梁７ａの掛かり代は、既設受梁３ａの掛かり代と同じ大きさに設定してもよい。 As shown in FIG. 3, the new receiving beam 6a provided in the longitudinal direction end of the new main body frame 5, that is, the new lower horizontal portion 6, has a larger allowance L2 than the existing receiving beam 2a of the existing main body frame 1. It is mounted on the building beam 11 via a jack bolt 14 for height adjustment and a flat plate 15 for height adjustment so as to be relatively movable. Note that the new receiving beam 7a provided at the other longitudinal end of the newly installed main body frame 5, that is, the new upper horizontal portion 7 is also hung on the building beam 13 in the same configuration. However, the new receiving beam 7a has a fixed end and is fixed so that it cannot move relative to the existing receiving beam 6a. Further, in the case of a fixed end, the hanging allowance of the new receiving beam 7a may be set to the same size as that of the existing receiving beam 3a.
なお、本実施例では、上階側である建屋梁１３側を固定端とし、下階側である建屋梁１１側を自由端としているが、これに限られず、少なくとも一方が自由端であればよい。 In this embodiment, the building beam 13 side on the upper floor side is a fixed end and the building beam 11 side on the lower floor side is a free end. However, the present invention is not limited to this, and at least one of them is a free end. Good.
また、建屋梁１１に、掛かり代Ｌ２を有する新設受梁６ａを収める設置スペースがない場合、既設受梁２ａの反既設本体枠１側を削り、設置スペースを設けるようにしてもよい。 Further, when the building beam 11 does not have an installation space for accommodating the new receiving beam 6a having the hanging allowance L2, the anti-existing body frame 1 side of the existing receiving beam 2a may be shaved to provide an installation space.
図４は、本実施例における連結部材の一例である。新設本体枠５と既設本体枠１とは、連結部材１６により連結されており、これによって、既設受梁２ａが建屋梁１１から外れた場合に既設本体枠１の落下を防止する。この連結部材１６は、既設本体枠１の自重が新設本体枠５に掛かったときに破断することのない強度を有するものに設定されている。 FIG. 4 is an example of a connecting member in the present embodiment. The newly installed main body frame 5 and the existing main body frame 1 are connected by a connecting member 16, thereby preventing the existing main body frame 1 from falling when the existing receiving beam 2 a is detached from the building beam 11. The connecting member 16 is set to have a strength that does not break when the weight of the existing main body frame 1 is applied to the new main body frame 5.
さらに、本実施例においては、既設受梁２ａが建屋梁１１に掛けられた状態において、連結部材１６は、新設本体枠５に、例えばボルトや溶接などにより固定されているとともに、既設本体枠１には連結部材１６に設けられた高さ調整部品１７を介して隙間なく当接している。高さ調整部品１７としては、例えばジャッキボルトなどを用いることができる。ここでは、高さ調整部品１７は、既設本体枠１に対して下方から当接する。なお、既設本体枠１と高さ調整部品１７との間は、水平方向に相対変位可能に当接している。これにより、既設本体枠１または新設本体枠５に長手方向への過度の力が加わった場合でも、両者が水平方向に相対変位することにより、既設本体枠１および新設本体枠５が塑性変形してしまうのを防止できる。 Furthermore, in this embodiment, in a state where the existing receiving beam 2a is hung on the building beam 11, the connecting member 16 is fixed to the new main body frame 5 by, for example, bolts or welding, and the existing main body frame 1 Are in contact with each other through a height adjustment component 17 provided on the connecting member 16 without a gap. For example, a jack bolt or the like can be used as the height adjustment component 17. Here, the height adjustment component 17 contacts the existing main body frame 1 from below. In addition, between the existing main body frame 1 and the height adjustment component 17, it is contacting | abutting so that relative displacement is possible in a horizontal direction. Thereby, even when an excessive force in the longitudinal direction is applied to the existing main body frame 1 or the new main body frame 5, the existing main body frame 1 and the new main body frame 5 are plastically deformed by relative displacement in the horizontal direction. Can be prevented.
図５は、本実施例における連結部材の他の例である。図４との違いは、連結部材１６の形状と固定されている場所のみであり、その他は図４と同様である。 FIG. 5 is another example of the connecting member in the present embodiment. The only difference from FIG. 4 is the shape of the connecting member 16 and the place where it is fixed, and the rest is the same as FIG.
なお、図４および図５では、連結部材１６は、新設本体枠５に固定されているとともに、高さ調整部品１７は、既設本体枠１に対して下方から当接する例を示したが、これに限られず、連結部材１６は、既設本体枠１に固定されているとともに、高さ調整部品１７は、新設本体枠５に対して上方から当接するようにしてもよい。すなわち、既設受梁２ａが建屋梁１１に掛けられた状態において、連結部材１６は、既設本体枠１と新設本体枠５とのうちの一方に固定されているとともに、他方には連結部材１６に設けられた高さ調整部品１７を介して隙間なく当接している構成とすればよい。 4 and 5, the connecting member 16 is fixed to the newly installed main body frame 5 and the height adjusting component 17 is in contact with the existing main body frame 1 from below. The connecting member 16 may be fixed to the existing main body frame 1 and the height adjusting component 17 may be in contact with the new main body frame 5 from above. That is, in a state where the existing receiving beam 2a is hung on the building beam 11, the connecting member 16 is fixed to one of the existing main body frame 1 and the new main body frame 5, and the other is connected to the connecting member 16 on the other side. What is necessary is just to set it as the structure contact | abutted without the clearance gap through the provided height adjustment component 17. FIG.
以上説明したような本実施例にあっては、例えば地震などで大きな層間変位が発生して建屋梁１１と建屋梁１３との間の間隔が過大になり、新設本体枠５および既設本体枠１と建屋梁１１との間隔が過大になっても、新設受梁６ａの掛かり代Ｌ２は、既設受梁２ａの掛かり代Ｌ１より大きく設定されていることから、既設のものよりも新設本体枠５が落下しにくくなり、既設のものより大きな層間変位に耐えることができる。また、既設受梁２ａのみが建屋梁１１から外れて、新設受梁６ａのみが建屋梁１１に掛かった状態になった場合でも、連結部材１６により既設本体枠１の自重は新設本体枠５で支えられ、既設本体枠１の落下を防止することができる。さらに、新設本体枠５または既設本体枠１と連結部材１６との間は高さ調整部品１７を介して隙間なく当接しているので、隙間をなくすための高さ調整が容易にできるとともに既設受梁２ａが建屋梁１１から外れた場合でも隙間分の落下による衝撃が発生するのを防止することができる。 In the present embodiment as described above, for example, a large interlayer displacement occurs due to an earthquake or the like, and the space between the building beam 11 and the building beam 13 becomes excessive, and the newly installed main body frame 5 and the existing main body frame 1. Even if the distance between the building beam 11 and the building beam 11 becomes excessive, the hanging allowance L2 of the new receiving beam 6a is set larger than the hanging allowance L1 of the existing receiving beam 2a. Is less likely to drop and can withstand greater interlayer displacement than existing ones. Even when only the existing receiving beam 2 a is detached from the building beam 11 and only the new receiving beam 6 a is hooked on the building beam 11, the weight of the existing main body frame 1 is reduced by the new main body frame 5 by the connecting member 16. It is supported and can prevent the existing main body frame 1 from falling. Further, since the new main body frame 5 or the existing main body frame 1 and the connecting member 16 are in contact with each other through the height adjusting component 17 without any gap, the height adjustment for eliminating the gap can be easily performed and the existing receiving frame can be easily received. Even when the beam 2 a is detached from the building beam 11, it is possible to prevent an impact due to a drop corresponding to the gap.
また、これまでの説明では、乗客コンベアの一例としてエスカレータを用いて説明したが、乗客コンベアの他の例として動く歩道などに適用してもよい。 Moreover, in the above description, although the escalator was demonstrated as an example of a passenger conveyor, you may apply to the moving walk etc. as another example of a passenger conveyor.
以上、本発明の実施例を説明してきたが、これまでの実施例で説明した構成はあくまで一例であり、本発明は、技術思想を逸脱しない範囲内で適宜変更が可能である。また、それぞれの実施例で説明した構成は、互いに矛盾しない限り、組み合わせて用いても良い。 The embodiments of the present invention have been described above.
