Abstract
Description
本発明は、乗客コンベア装置に関する。 The present invention relates to a passenger conveyor device.
乗客コンベアの本体枠の支持方法は、一般に、建築構造物の受梁に本体枠の終端部に設けられる支持アングルを載置する構成となっており、本体枠の支持アングルと建築構造物には、例えば特許文献１に記載されるように、本体枠の一方の終端部を建築構造物に対して移動不能に固定する固定部と、本体枠の他方の終端部を建築構造物に載置する非固定部とを備えるとともに、本体枠と、非固定部の位置する建築構造物との間に、本体枠の長手方向の移動を可能にする間隔を有し、本体枠の長手方向の移動による建築構造物との間の位置ずれに対して、その長手方向に追従可能な滑動部を非固定部に備えている。また、この隙間は、建築構造物の層間変位を考慮したもので、本体枠が建築構造物の受梁に衝突しない隙間にしている。 The method of supporting the main body frame of the passenger conveyor is generally configured to place a support angle provided at the end of the main body frame on the receiving beam of the building structure. For example, as described in Patent Document 1, a fixing portion that fixes one end portion of the main body frame so as to be immovable with respect to the building structure, and the other end portion of the main body frame are placed on the building structure. A non-fixed portion, and a space that allows movement of the main body frame in the longitudinal direction between the main body frame and the building structure where the non-fixed portion is located. The non-fixed portion is provided with a sliding portion that can follow the longitudinal direction of the positional deviation between the building structure and the building structure. Further, this gap takes into account the interlayer displacement of the building structure, and is set so that the main body frame does not collide with the receiving beam of the building structure.
しかしながら、前述したものでは、乗客コンベアの揚程が大きくなった場合に、建築構造物の受梁に本体枠を固定する固定部において、大地震時や強風時などの大きな揺れに耐えうる強度を確保する構造が複雑となり、据付時にも多大な労力と時間が発生してしまう。 However, with the above-mentioned, when the lift of the passenger conveyor becomes large, the fixing part that fixes the body frame to the receiving beam of the building structure ensures the strength to withstand large shaking such as during a large earthquake or strong wind The structure to perform becomes complicated, and a great deal of labor and time are generated even during installation.
また、本体枠の両端の支持アングルを非固定として、本体枠の支持アングルと建築構造物の受梁との間に、建築構造物の想定される最大の層間変位の約１／２の隙間を夫々設け、両端の支持アングルのかかり代を夫々長くすることにより脱落を防ぐ方法もある。この場合は、強固な固定構造は必須ではない。しかし、この隙間を超える地震の揺れが生じた際には、本体枠の端部と建築構造物の受梁が衝突する。特に、上部支持アングル側では機械室に駆動装置などの重量物があるため、本体枠の重量の偏りが大きくなり、上部支持アングルと建築構造物の受梁との間の摩擦は、下部支持アングルよりも大きくなるため揺れが生じた際に上部支持アングルでは滑動しにくく、その結果、下部支持アングルの方が想定よりも大きく滑動し、下部側の隙間が０になって下部側の本体枠や建築構造物の受梁が破損しやすくなるという問題が発生する。 In addition, the support angle at both ends of the main body frame is not fixed, and a gap of about 1/2 of the maximum interlayer displacement assumed for the building structure is provided between the support angle of the main body frame and the receiving beam of the building structure. There is also a method of preventing dropout by providing each of them and increasing the allowance of the support angle at both ends. In this case, a strong fixing structure is not essential. However, when an earthquake shake exceeding this gap occurs, the end of the main body frame and the receiving beam of the building structure collide. In particular, on the upper support angle side, there is a heavy load such as a drive device in the machine room, so the weight of the main body frame becomes larger, and the friction between the upper support angle and the receiving beam of the building structure is lower than the lower support angle. Therefore, the upper support angle is less likely to slide when the swaying occurs. As a result, the lower support angle slides more than expected, and the lower side clearance becomes 0, and the lower side body frame and There arises a problem that the receiving beam of the building structure is easily damaged.
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、大地震時などの大きな揺れに対して、建築構造物の受梁や本体枠の破損を防ぐとともに、本体枠が建築構造物の受梁から脱落するのを防止した乗客コンベア装置を提供することにある。 The present invention was made from the actual state of the prior art described above. The purpose of the present invention is to prevent damage to the beam of the building structure and the main body frame against a large shaking such as during a large earthquake, and the main body frame can be constructed. It is an object of the present invention to provide a passenger conveyor device that prevents the structure from falling off the receiving beam.
前記目的を達成するために、本発明は、例えば、建築構造物の一方の受梁と他方の受梁とを跨ぐように架設される本体枠と、無端状に連結されて前記本体枠内を循環移動する複数のステップと、前記本体枠内に設けられ、前記複数のステップを駆動する駆動装置と、前記本体枠の一方および他方の終端部にそれぞれ設けられ、前記一方および他方の受梁に載置される一方および他方の支持アングルとを備えた乗客コンベア装置において、前記一方および他方の支持アングルの長さは、前記本体枠の長手方向における前記本体枠と建築構造物との間の隙間が０になっても前記本体枠が脱落しない長さに設定されているとともに、前記本体枠の長手方向における前記本体枠と建築構造物との間の隙間のうち、前記駆動装置が配置されている側の隙間よりも、反対側の隙間の方が、大きく設定され、前記一方および他方の支持アングルのうち、前記駆動装置が配置されている側の支持アングルの強度よりも、反対側の支持アングルの強度の方が、大きく設定されていることを特徴とする。 In order to achieve the above object, the present invention, for example, includes a main body frame constructed so as to straddle one receiving beam and the other receiving beam of a building structure, and endlessly connected to the inside of the main body frame. A plurality of steps that circulate, a driving device that is provided in the main body frame and that drives the plurality of steps, and is provided at one and the other end of the main body frame, respectively, In the passenger conveyor apparatus provided with one and the other support angles to be placed, the length of the one and the other support angles is a gap between the main body frame and the building structure in the longitudinal direction of the main body frame. Is set to such a length that the main body frame does not fall off even when the value of 0 is reached, and the driving device is disposed in the gap between the main body frame and the building structure in the longitudinal direction of the main body frame. Gap on the side The gap on the opposite side is set to be larger, and the strength of the support angle on the opposite side is greater than the strength of the support angle on the side where the driving device is disposed, among the one and the other support angles. The method is characterized in that it is set larger.
本発明によれば、駆動装置が配置されている側の支持アングルの方が反対側の支持アングルよりも動きにくいことを考慮して、駆動装置が配置されている側の隙間よりも、反対側の隙間の方が、大きく設定されるので、大地震時などの大きな揺れに対して、建築構造物の受梁や本体枠の破損を防ぐことができる。また、この隙間の設定を考慮して、支持アングルの長さや強度が適切に設定されているので、本体枠が建築構造物の受梁から脱落するのを防止することができる。 According to the present invention, in consideration of the fact that the support angle on the side where the drive device is arranged is less movable than the support angle on the opposite side, it is on the opposite side than the gap on the side where the drive device is arranged. Since the gap is set larger, it is possible to prevent damage to the receiving beam of the building structure and the main body frame against a large shaking such as during a large earthquake. In addition, since the length and strength of the support angle are appropriately set in consideration of the setting of the gap, the main body frame can be prevented from falling off the receiving beam of the building structure.
本発明の実施例を、図面を参照しながら説明する。尚、各図および各実施例において、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 each drawing and each embodiment, the same or similar components are denoted by the same reference numerals, and description thereof is omitted.
実施例１の乗客コンベア装置は、例えばエスカレータであり、図１に示すように、建築構造物の上階床面と下階床面とを跨ぐように本体枠１が架設されており、この本体枠１の両終端部には、それぞれ本体枠１を支持する上部支持アングル２、及び下部支持アングル３が設けられている。また、本体枠１内には、無端状に連結されて本体枠１内を循環移動する図示しない複数のステップが設けられている。本体枠１の上部水平部には機械室４があり、ステップを駆動する駆動装置１２（例えばモータや減速器など）や電気盤が収められる。 The passenger conveyor apparatus of Example 1 is an escalator, for example, and as shown in FIG. 1, the main body frame 1 is constructed so as to straddle the upper floor surface and the lower floor surface of the building structure. An upper support angle 2 and a lower support angle 3 that support the main body frame 1 are provided at both end portions of the frame 1. The main body frame 1 is provided with a plurality of steps (not shown) that are connected endlessly and circulate in the main body frame 1. A machine room 4 is provided in the upper horizontal portion of the main body frame 1 and houses a drive device 12 (for example, a motor, a speed reducer, etc.) and an electric panel for driving the steps.
下部支持アングル３は、図１、図２、図４に示すように、建築構造物の下部受梁６に相対移動可能に載置されている。そして、本体枠１の長手方向における本体枠１（ここでは下部支持アングル３の鉛直片部分も本体枠１の一部とみなしている）と建築構造物（ここでは下部受梁６）との間の隙間１０は、地震時や強風時などにおいて建築構造物が想定される大きさで揺れて上部受梁５と下部受梁６との間の間隔が最も小さくなったときでも０にならない大きさに設定されている。下部支持アングル３は、本体枠１の長手方向の移動に追従可能となっているとともに、本体枠１の短手方向には固定金具７によって移動が制限される。下部支持アングル３と下部受梁６とのかかり代の大きさに影響する下部支持アングル３の長さは、本体枠１の長手方向における本体枠１と建築構造物との間の隙間１０が０になっても本体枠１が脱落しない長さに設定されている。例えば、かかり代として、建築構造物が想定される大きさで揺れて上部受梁５と下部受梁６との間の間隔が最も大きくなったときの標準位置からの変位量に加え、反対側である上部側における本体枠１と建築構造物（ここでは上部受梁５）との間の隙間９を合わせた値以上を確保する。尚、ここでは、下部支持アングル３と下部受梁６との間に、高さ調整のための支持部材８が配置されているが、この場合も下部支持アングル３は下部受梁６に載置されているとの表現に含まれるものとする。図２に示すように、支持部材８は下部支持アングル３の根元側において突出した突出部を有する構造となっており、できるだけ下部支持アングル３の根元側に近いこの突出部の部分で下部支持アングル３に当接して支えるようにすることで下部支持アングル３にかかる負荷を低減している。但し、これに限られず、例えば支持部材８に突出部を設けず全体で受けるようにしてもよい。 As shown in FIGS. 1, 2, and 4, the lower support angle 3 is placed on a lower receiving beam 6 of a building structure so as to be relatively movable. And between the main body frame 1 (here, the vertical piece of the lower support angle 3 is also regarded as a part of the main body frame 1) and the building structure (here, the lower support beam 6) in the longitudinal direction of the main body frame 1 The gap 10 is not large even when the distance between the upper receiving beam 5 and the lower receiving beam 6 becomes the smallest when the building structure is shaken at an assumed size during an earthquake or a strong wind. Is set to The lower support angle 3 can follow the movement of the main body frame 1 in the longitudinal direction, and the movement of the lower support angle 3 is restricted by the fixing bracket 7 in the short direction of the main body frame 1. The length of the lower support angle 3 that affects the magnitude of the allowance between the lower support angle 3 and the lower support beam 6 is such that the gap 10 between the main body frame 1 and the building structure in the longitudinal direction of the main body frame 1 is 0. The length of the main body frame 1 is set so as not to fall off even if it becomes. For example, in addition to the amount of displacement from the standard position when the interval between the upper and lower beam-receiving beams 5 and 6 is the largest as the building structure swings at the assumed size, the opposite side That is, a value equal to or larger than the combined value of the gap 9 between the main body frame 1 and the building structure (here, the upper receiving beam 5) on the upper side is secured. Here, a support member 8 for adjusting the height is disposed between the lower support angle 3 and the lower support beam 6. In this case, the lower support angle 3 is also placed on the lower support beam 6. It should be included in the expression that As shown in FIG. 2, the support member 8 has a structure having a protrusion protruding on the base side of the lower support angle 3, and the lower support angle is as close as possible to the base side of the lower support angle 3. The load applied to the lower support angle 3 is reduced by abutting and supporting the 3. However, the present invention is not limited to this, and for example, the support member 8 may be received as a whole without providing a protrusion.
一方、上部支持アングル２は、図１、図３、図５に示すように、建築構造物の上部受梁５に相対移動可能に載置されている。上部支持アングル２側の構造は、基本的には下部支持アングル３側の構造と同様になっているので詳細説明は省略し、以下では下部支持アングル３側と異なる部分のみ説明する。 On the other hand, as shown in FIGS. 1, 3, and 5, the upper support angle 2 is placed on the upper receiving beam 5 of the building structure so as to be relatively movable. Since the structure on the upper support angle 2 side is basically the same as the structure on the lower support angle 3 side, detailed description thereof will be omitted, and only the parts different from the lower support angle 3 side will be described below.
まず、異なる部分として、本体枠１の長手方向における本体枠１と建築構造物との間の隙間９、１０のうち、駆動装置１２が配置されている側の隙間９よりも、反対側の隙間１０の方が、大きく設定されている。本体枠１内に駆動装置１２が配置されていることで、本体枠１の重量の偏りが生じ、重い側、すなわち駆動装置１２が配置されている側の支持アングルである上部支持アングル２の方が反対側の支持アングルである下部支持アングル３よりも動きにくく、駆動装置が配置されている側の隙間よりも、反対側の隙間の方が変動しやすい。したがって、仮に隙間９と隙間１０の大きさを同じに設定した場合には、大地震時などの大きな揺れに対して、隙間１０が先に０になってしまい、建築構造物の受梁や本体枠１の破損が生じる可能性がある。これに対して、本実施例のように駆動装置１２が配置されている側の隙間９よりも、反対側の隙間１０の方が、大きく設定されていることで、建築構造物の受梁や本体枠１の破損を防ぐことができる。 First, as a different part, among the gaps 9 and 10 between the main body frame 1 and the building structure in the longitudinal direction of the main body frame 1, a gap on the opposite side of the gap 9 on the side where the driving device 12 is disposed. 10 is set larger. Since the drive device 12 is arranged in the main body frame 1, the weight of the main body frame 1 is biased, and the upper support angle 2 which is the support angle on the heavy side, that is, the side on which the drive device 12 is arranged is arranged. Is less movable than the lower support angle 3 which is the opposite support angle, and the gap on the opposite side is more likely to fluctuate than the gap on the side where the drive device is disposed. Therefore, if the sizes of the gap 9 and the gap 10 are set to be the same, the gap 10 becomes 0 first in response to a large shake such as during a large earthquake, and the receiving beam or main body of the building structure. There is a possibility that the frame 1 is broken. On the other hand, the gap 10 on the opposite side is set larger than the gap 9 on the side where the driving device 12 is arranged as in the present embodiment, so that the receiving beam of the building structure or Breakage of the main body frame 1 can be prevented.
次に異なる部分として、支持アングルのうち、駆動装置１２が配置されている側の支持アングルである上部支持アングル２の強度よりも、反対側の支持アングルである下部支持アングル３の強度の方が、大きく設定されている。下部支持アングル３は、隙間１０を隙間９より大きく設定したことにより、上部支持アングル２の場合よりも支持アングルの先端側で重量を支持しており、高い負荷がかかる。したがって、下部支持アングル３の強度を上部支持アングル２よりも大きく設定した。例えば、下部支持アングル３の厚さを厚くすることで強度を大きくすることができ、望ましくは、下部支持アングル３の厚さは、上部支持アングル２の厚さの２倍以上とすることにより強度を確保する。上部支持アングル２は、駆動装置１２による本体枠１の重量の偏りにより支持する重量が大きくなるが、据付状態での長期的支持において、隙間９が小さく設定されているので、上部支持アングル２の根元側（本体枠１に近い側）で支持できるため、下部支持アングル３のような強度を必要としない。上部支持アングル２は地震などにより本体枠１が下部側に寄った場合において、先端側で重量を支持することとなるが、この場合の強度は、本体枠１が建築構造物の揺れにより一時的に位置ずれした時だけ支持できる強度であればよく、短期的な支持に必要な強度で十分であり、長期的な支持に必要な強度までは要求されない。 Next, as a different part, among the support angles, the strength of the lower support angle 3 which is the support angle on the opposite side is stronger than the strength of the upper support angle 2 which is the support angle on the side where the driving device 12 is disposed. , Is set large. Since the lower support angle 3 sets the gap 10 to be larger than the gap 9, the lower support angle 3 supports the weight on the tip side of the support angle as compared with the case of the upper support angle 2, and a higher load is applied. Therefore, the strength of the lower support angle 3 is set larger than that of the upper support angle 2. For example, the strength can be increased by increasing the thickness of the lower support angle 3. Preferably, the thickness of the lower support angle 3 is set to be twice or more the thickness of the upper support angle 2. Secure. The upper support angle 2 has a large supporting weight due to the weight deviation of the main body frame 1 by the driving device 12. However, since the gap 9 is set small in the long-term support in the installed state, the upper support angle 2 Since it can be supported on the base side (side closer to the main body frame 1), the strength as in the lower support angle 3 is not required. The upper support angle 2 supports the weight at the tip side when the main body frame 1 is moved to the lower side due to an earthquake or the like, but the strength in this case is temporary due to the main body frame 1 being shaken by the building structure. However, the strength required for short-term support is sufficient, and the strength required for long-term support is not required.
尚、上部支持アングル２と上部受梁５とのかかり代の大きさに影響する上部支持アングル２の長さは、本体枠１の長手方向における本体枠１と建築構造物との間の隙間９が０になっても本体枠１が脱落しない長さに設定されていることに関しては、下部支持アングル３の場合と同様である。例えば、かかり代として、建築構造物が想定される大きさで揺れて上部受梁５と下部受梁６との間の間隔が最も大きくなったときの標準位置からの変位量に加え、反対側である上部側における本体枠１と建築構造物（ここでは上部受梁６）との間の隙間１０を合わせた値以上を確保することに関しても、隙間９と隙間１０とが入れ替わっただけで基本的には下部支持アングル３の場合と同様である。 It should be noted that the length of the upper support angle 2 that affects the magnitude of the allowance between the upper support angle 2 and the upper receiving beam 5 is the gap 9 between the main body frame 1 and the building structure in the longitudinal direction of the main body frame 1. The length is set so that the main body frame 1 does not fall off even when 0 becomes 0, as in the case of the lower support angle 3. For example, in addition to the amount of displacement from the standard position when the interval between the upper and lower beam-receiving beams 5 and 6 is the largest as the building structure swings at the assumed size, the opposite side In order to secure a value equal to or greater than the total value of the gap 10 between the main body frame 1 and the building structure (here, the upper receiving beam 6) on the upper side, the basic matter is that the gap 9 and the gap 10 are simply replaced. This is the same as the case of the lower support angle 3.
このように、駆動装置１２が配置されている側を考慮した建築構造物の受梁や本体枠１の破損を防ぐための隙間の設定を考慮して、支持アングルの長さや強度が適切に設定されているので、本体枠が建築構造物の受梁から脱落するのを防止することができる。 In this way, the length and strength of the support angle are appropriately set in consideration of the setting of the gaps for preventing damage to the receiving beam of the building structure and the main body frame 1 in consideration of the side on which the driving device 12 is disposed. Therefore, the main body frame can be prevented from falling off the receiving beam of the building structure.
次に、実施例２の乗客コンベア装置について、実施例１との違いを中心に説明する。実施例１では、上部支持アングル２および下部支持アングル３は、それぞれ上部受梁５および下部受梁６に対して相対移動可能に載置されている、いわゆる両端非固定の構造であった。これに対して、実施例２では、支持アングルのうち、駆動装置１２が配置されている側の支持アングルは、建築構造物の受梁に対して所定の強度で固定されているとともに、この所定の強度による固定は、所定の大きさ以上の揺れが発生した時に固定が解除されて支持アングルと受梁とが相対移動可能となる強度に設定された、いわゆる準固定の構造とし、反対側は、実施例１と同様のいわゆる非固定の構造とした。 Next, the passenger conveyor apparatus according to the second embodiment will be described focusing on differences from the first embodiment. In the first embodiment, the upper support angle 2 and the lower support angle 3 have a so-called unfixed structure in which the upper support beam 5 and the lower support beam 6 are placed so as to be movable relative to the upper support beam 5 and the lower support beam 6, respectively. On the other hand, in the second embodiment, the support angle on the side where the driving device 12 is arranged among the support angles is fixed to the receiving beam of the building structure with a predetermined strength. The fixing by the strength of the so-called quasi-fixed structure is set so that the fixing is released when the shaking of a predetermined size or more occurs and the support angle and the receiving beam are relatively movable, and the opposite side is A so-called non-fixed structure similar to that in Example 1 was adopted.
準固定の構造の実現方法としては、例えば、図６、図７に示すように、実施例１の図３、図５に、上部受梁５に固定された位置ずれ止め金具１１を追加し、位置ずれ止め金具１１と上部支持アングル２とを例えば溶接などにより所定の強度で固定するとともに、この所定の強度による固定は、所定の大きさ以上の揺れが発生した時に固定が解除される強度する。他の実現方法としては、例えば、上部支持アングル２をピンなどにより上部受梁５に固定し、所定の大きさ以上の揺れが発生した時にピンが破断して固定が解除されるようにする。 As a method of realizing the semi-fixed structure, for example, as shown in FIGS. 6 and 7, the misalignment stopper 11 fixed to the upper receiving beam 5 is added to FIGS. 3 and 5 of the first embodiment, The misalignment stopper 11 and the upper support angle 2 are fixed with a predetermined strength, for example, by welding, and the fixing with the predetermined strength increases the strength at which the fixing is released when a vibration of a predetermined magnitude or more occurs. . As another realization method, for example, the upper support angle 2 is fixed to the upper receiving beam 5 with a pin or the like, and the pin is broken and the fixing is released when a swing of a predetermined size or more occurs.
このような準固定の構造により、中規模以下の揺れの際に、準固定側では支持アングルと受梁との摩擦力と、準固定の構造により、本体枠の位置ずれを防ぐことができる。そして、大規模な揺れの場合は、非固定の構造になるので、実施例１と同様の効果を得られる。また、準固定の構造とすることで、大規模な揺れに耐えるような固定の強度は不要であるため、通常の固定端の構造よりも簡易的な構造にできる。 Such a semi-fixed structure can prevent the body frame from being displaced due to the frictional force between the support angle and the receiving beam and the semi-fixed structure on the semi-fixed side in the case of a moderate or smaller swing. And in the case of a large-scale shaking, since it becomes an unfixed structure, the same effect as Example 1 can be acquired. In addition, since a semi-fixed structure does not require a fixing strength that can withstand large-scale shaking, the structure can be simpler than a normal fixed end structure.
以上、本発明の実施例を説明してきたが、これまでの各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。 As mentioned above, although the Example of this invention has been described, the structure demonstrated by each Example so far is an example to the last, and this invention can be suitably changed within the range which does not deviate from a technical idea. Further, the configurations described in the respective embodiments may be used in combination as long as they do not contradict each other.
例えば、ここでは本体枠１の上部側に駆動装置１２が配置されている場合を例に説明しているが、本体枠１の下部側に駆動装置１２が配置されている場合は、上部と下部の構成を逆にすればよい。また、乗客コンベア装置の一例としてエスカレータに適用した例を示したが、乗客コンベア装置の他の例として動く歩道に適用してもよい。 For example, the case where the driving device 12 is disposed on the upper side of the main body frame 1 is described here as an example, but when the driving device 12 is disposed on the lower side of the main body frame 1, the upper and lower portions are described. The configuration of the above may be reversed. Moreover, although the example applied to the escalator was shown as an example of a passenger conveyor apparatus, you may apply to the moving sidewalk as another example of a passenger conveyor apparatus.
