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 system.

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が用いられる。例えば、特許文献1は、本体枠の支持アングルと建築構造物について、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、その長手方向にのみ追従可能な滑動部を非固定部に備える構成を開示している。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 frame of a passenger conveyor generally involves placing a support angle at the end of the main frame on the support beam of the building structure. For example, Patent Document 1 discloses a structure in which the support angle of the main frame and the building structure are provided with a fixed part that fixes one end of the main frame to the building structure so that it cannot move, and a non-fixed part that places the other end of the main frame on the building structure, and there is a gap between the main frame and the building structure where the non-fixed part is located that allows the main frame to move in the longitudinal direction, and the non-fixed part is provided with a sliding part that can follow only in the longitudinal direction when the main frame moves in the longitudinal direction and the building structure shifts. This gap is also designed to take into account the inter-story displacement of the building structure, and is a gap that does not allow the main frame to collide with the support beam of the building structure.

特開平11-314873号公報Japanese Patent Application Laid-Open No. 11-314873

しかしながら、特許文献1に代表される従来技術では、乗客コンベアの揚程が大きい場合に、建築構造物の受梁に本体枠を固定する固定部において、大地震時の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。そこで、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考えられる。この場合は、強固な固定構造は必須ではなく、短手方向にのみ固定すればよい。しかし、支持アングルの長手方向への可動範囲を確保しつつ、短手方向に固定する構造とするには、支持アングルの周囲に十分なスペースを要する。特に既設の乗客コンベアに対して脱落防止の改造を施す場合、建築構造物の制約から支持アングルの周囲にスペースが無く、短手方向の固定が困難となる場合があった。 However, in the conventional technology typified by Patent Document 1, when the lift height of the passenger conveyor is large, the structure for securing the strength to withstand the shaking during a major earthquake becomes complicated at the fixing part that fixes the main frame to the support beam of the building structure, and a lot of effort and time is required for installation. Therefore, a method can be considered in which the support angles at both ends of the main frame are not fixed, and a gap is provided between the support angles of the main frame and the support beam of the building structure, and the overlap of the support angles at both ends is lengthened to prevent falling off. In this case, a strong fixing structure is not essential, and it is sufficient to fix only in the short direction. However, in order to secure the movable range of the support angle in the longitudinal direction while fixing it in the short direction, sufficient space is required around the support angle. In particular, when modifying an existing passenger conveyor to prevent falling off, there are cases where there is no space around the support angle due to the constraints of the building structure, making it difficult to fix it in the short direction.

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、簡易な構成で脱落や破損を防止する乗客コンベア装置を提供することにある。 The present invention was made in response to the current state of the prior art described above, and its purpose is to provide a passenger conveyor device with a simple structure that prevents falling off and damage.

前記目的を達成するために、本発明は、建築構造物の一方の受梁と他方の受梁とに架け渡される本体枠と、前記本体枠の長手方向における両側の終端部にそれぞれ設けられ、前記受梁に載置されて前記本体枠を支持する支持部材とを備えた乗客コンベア装置において、少なくともいずれかの受梁に取り付けられ、前記支持部材の上面と非接触で対向する面を有する受梁側固定具と、前記支持部材の上面に取り付けられ、前記受梁側固定具に前記本体枠の短手方向の両側から当接する本体枠側固定具と、を備え、前記本体枠は、前記受梁側固定具が取り付けられた受梁に対して、前記長手方向に摺動可能であることを特徴としている。 To achieve the above object, the present invention provides a passenger conveyor system that includes a main frame that is spanned between one support beam and the other support beam of an architectural structure, and support members that are provided at both longitudinal end portions of the main frame and are placed on the support beams to support the main frame, the system also including a support beam side fixture that is attached to at least one of the support beams and has a surface that faces the upper surface of the support member without contacting it, and a main frame side fixture that is attached to the upper surface of the support member and abuts against the support beam side fixture from both sides in the short direction of the main frame, and the main frame is characterized in that it is capable of sliding in the longitudinal direction relative to the support beam to which the support beam side fixture is attached.

本発明によれば、簡易な構成で脱落や破損を防止する乗客コンベア装置を提供することができる。 The present invention provides a passenger conveyor device with a simple configuration that prevents falling off or damage.

以下、本発明に係る乗客コンベア装置の実施の形態を図に基づき説明する。 The following describes an embodiment of the passenger conveyor system according to the present invention with reference to the drawings.

乗客コンベア装置は、例えばエスカレータであり、図1~図5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が架け渡されている。本体枠1の両側の終端部には、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。上部支持アングル2及び下部支持アングル3は、特許請求の範囲における支持部材に対応する。 The passenger conveyor device is, for example, an escalator, and as shown in Figures 1 to 5, a main body frame 1 is suspended across the upper floor surface and the lower floor surface of a building structure. An upper support angle 2 and a lower support angle 3 are provided at the end portions on both sides of the main body frame 1, respectively, to support the main body frame 1. The upper support angle 2 and the lower support angle 3 correspond to the support members in the claims.

上部支持アングル2は、図1に示すように、建築構造物の上部受梁4に載置されており、下部支持アングル3は、建築構造物の下部受梁5に載置される。上部支持アングル2の上面とは、上部支持アングル2が有する面のうち、上部受梁4に載置される面と表裏の関係にある面であり、上階床面と平行な面である。同様に、下部支持アングル3の上面とは、下部支持アングル3が有する面のうち、下部受梁5に載置される面と表裏の関係にある面であり、下階床面と平行な面である。 As shown in FIG. 1, the upper support angle 2 is placed on the upper support beam 4 of the building structure, and the lower support angle 3 is placed on the lower support beam 5 of the building structure. The top surface of the upper support angle 2 is the surface of the upper support angle 2 that is in a front-back relationship with the surface that is placed on the upper support beam 4, and is parallel to the upper floor floor surface. Similarly, the top surface of the lower support angle 3 is the surface of the lower support angle 3 that is in a front-back relationship with the surface that is placed on the lower support beam 5, and is parallel to the lower floor floor surface.

上部支持アングル2は、本体枠1の長辺方向(長手方向)のスライド移動に対して追従可能であるが、短辺方向(短手方向)の動きは支持アングル上面プレート6と固定金具7によって制限される。支持アングル上面プレート6は、特許請求の範囲における本体枠側固定具に対応する。同様に、下部支持アングル3は、本体枠1の長辺方向(長手方向)のスライド移動に対して追従可能であるが、短辺方向(短手方向)の動きは支持アングル上面プレート6と固定金具7によって制限される。 The upper support angle 2 can follow the sliding movement of the main frame 1 in the long side direction (lengthwise), but its movement in the short side direction (short side direction) is restricted by the support angle top plate 6 and the fixing bracket 7. The support angle top plate 6 corresponds to the main frame side fixing device in the claims. Similarly, the lower support angle 3 can follow the sliding movement of the main frame 1 in the long side direction (lengthwise), but its movement in the short side direction (short side direction) is restricted by the support angle top plate 6 and the fixing bracket 7.

上部支持アングル2と上部受梁4とのかかり代は、建築構造物の層間変位量に加えて、下部側における下部支持アングル3と下部受梁5との隙間10を合わせた値以上を確保する。同様に、下部支持アングル3と下部受梁5とのかかり代は、建築構造物の層間変位量に加えて、上部側における上部支持アングル2と上部受梁4との隙間9を合わせた値以上を確保する。 The overlap between the upper support angle 2 and the upper support beam 4 must be greater than or equal to the amount of inter-story displacement of the building structure plus the gap 10 between the lower support angle 3 and the lower support beam 5 at the lower side. Similarly, the overlap between the lower support angle 3 and the lower support beam 5 must be greater than or equal to the amount of inter-story displacement of the building structure plus the gap 9 between the upper support angle 2 and the upper support beam 4 at the upper side.

上部側において、支持アングル上面プレート6は、上部支持アングル2の上面の左右端、すなわち短手の辺の両端側にそれぞれ取り付ける。固定金具7は、特許請求の範囲における受梁側固定具であり、板状の金属をL字型に曲げて形成される。固定金具7は、上部支持アングル2の上面と非接触で対向し且つ長手方向に平行な第1の面と、第1の面と逆側の縁で上部受梁4に取り付けられる第2の面とを有する。固定金具7の上部受梁4に対する取り付けは、例えば溶接などを用いる。図4では、固定金具7は溶接部7aで上部受梁4に溶接されている。 On the upper side, the support angle upper plate 6 is attached to the left and right ends of the upper surface of the upper support angle 2, i.e., both ends of the short side. The fixing bracket 7 is a beam-side fixing device as defined in the claims, and is formed by bending a metal plate into an L-shape. The fixing bracket 7 has a first surface that faces the upper surface of the upper support angle 2 without contact and is parallel to the longitudinal direction, and a second surface that is attached to the upper beam 4 at the edge opposite the first surface. The fixing bracket 7 is attached to the upper beam 4 by, for example, welding. In FIG. 4, the fixing bracket 7 is welded to the upper beam 4 at the welded portion 7a.

また、固定金具7の第1の面は、上部支持アングル2の上面中央で、2つの支持アングル上面プレート6の間に設置する。すなわち、上部支持アングル2の上面に取り付けられた2つの支持アングル上面プレート6は、固定金具7に本体枠1の短手方向の両側から当接し、本体枠1が上部受梁4に対して短手方向に動くことを制限する。 The first surface of the fixing bracket 7 is installed in the center of the top surface of the upper support angle 2, between the two support angle top plates 6. In other words, the two support angle top plates 6 attached to the top surface of the upper support angle 2 abut against the fixing bracket 7 from both sides in the short direction of the main frame 1, restricting the main frame 1 from moving in the short direction relative to the upper support beam 4.

ここで、固定金具7の第1の面の下面と上部支持アングル2の上面との隙間11は、1mm以上となるように、固定金具7の下面を切断して高さを調整する。固定金具7と上部支持アングル2との間に隙間を設けることにより、地震時の上下振動が固定金具に伝わり、破損することを防ぐことができる。また、固定金具7の、上部受梁4での取り付け位置は、上部支持アングル2の先端から、上部支持アングル2と上部受梁4の隙間9だけ間隔を取ることにより、上部支持アングル2との衝突を防ぐ。 The height of the bottom surface of the fixing bracket 7 is adjusted by cutting it so that the gap 11 between the bottom surface of the first face of the fixing bracket 7 and the top surface of the upper support angle 2 is 1 mm or more. By providing a gap between the fixing bracket 7 and the upper support angle 2, it is possible to prevent vertical vibrations during an earthquake from being transmitted to the fixing bracket and damaging it. In addition, the attachment position of the fixing bracket 7 on the upper support beam 4 is spaced from the tip of the upper support angle 2 by the gap 9 between the upper support angle 2 and the upper support beam 4, thereby preventing collision with the upper support angle 2.

下部側において、支持アングル上面プレート6は、下部支持アングル3の上面の左右端、すなわち短手の辺の両端側にそれぞれ取り付ける。固定金具7は、特許請求の範囲における受梁側固定具であり、板状の金属をL字型に曲げて形成される。固定金具7は、下部支持アングル3の上面と非接触で対向し且つ長手方向に平行な第1の面と、第1の面と逆側の縁で下部受梁5に取り付けられる第2の面とを有する。固定金具7の下部受梁5に対する取り付けは、例えば溶接などを用いる。 On the lower side, the support angle upper plate 6 is attached to the left and right ends of the upper surface of the lower support angle 3, i.e., both ends of the shorter side. The fixing bracket 7 is the beam-side fixing device in the claims, and is formed by bending a metal plate into an L-shape. The fixing bracket 7 has a first surface that faces the upper surface of the lower support angle 3 without contact and is parallel to the longitudinal direction, and a second surface that is attached to the lower support beam 5 at the edge opposite the first surface. The fixing bracket 7 is attached to the lower support beam 5 by, for example, welding.

また、固定金具7の第1の面は、下部支持アングル3の上面中央で、2つの支持アングル上面プレート6の間に設置する。すなわち、下部支持アングル3の上面に取り付けられた2つの支持アングル上面プレート6は、固定金具7に本体枠1の短手方向の両側から当接し、本体枠1が上部受梁4に対して短手方向に動くことを制限する。 The first surface of the fixing bracket 7 is installed in the center of the upper surface of the lower support angle 3, between the two support angle upper plates 6. In other words, the two support angle upper plates 6 attached to the upper surface of the lower support angle 3 abut against the fixing bracket 7 from both sides in the short direction of the main frame 1, restricting the main frame 1 from moving in the short direction relative to the upper support beam 4.

ここで、固定金具7の第1の面の下面と下部支持アングル3の上面との隙間11は、1mm以上となるように、固定金具7の下面を切断して高さ調整する。固定金具7と下部支持アングル3との間に隙間を設けることにより、地震時の上下振動が固定金具に伝わり、破損することを防ぐことができる。また、固定金具7の、下部受梁5での取り付け位置は、下部支持アングル3の先端から、下部支持アングル3と下部受梁5の隙間10だけ間隔を取ることにより、下部支持アングル3との衝突を防ぐ。 The bottom surface of the fixing bracket 7 is cut to adjust the height so that the gap 11 between the bottom surface of the first face of the fixing bracket 7 and the top surface of the lower support angle 3 is 1 mm or more. By providing a gap between the fixing bracket 7 and the lower support angle 3, it is possible to prevent vertical vibrations during an earthquake from being transmitted to the fixing bracket and damaging it. In addition, the attachment position of the fixing bracket 7 on the lower support beam 5 is spaced from the tip of the lower support angle 3 by the gap 10 between the lower support angle 3 and the lower support beam 5, thereby preventing collision with the lower support angle 3.

ここで、本発明に係る乗客コンベア装置の第2の実施の形態を実施例2として図に基づき説明する。なお、前述の実施例で説明した構成要素と同等の構成要素には同一符号を付して説明を適宜省略する。 Here, a second embodiment of the passenger conveyor system according to the present invention will be described as Example 2 with reference to the drawings. Note that components equivalent to those described in the previous example will be given the same reference numerals and descriptions thereof will be omitted as appropriate.

実施例2の乗客コンベア装置は、図6~図9に示すように、実施例1において、支持アングル上面プレート6を延長し、追加プレート8を追加したものである。追加プレート8は、特許請求の範囲における延長部材に対応する。追加プレート8は、支持アングルの受梁側に設けられ、支持アングル上面プレート6は、支持アングルと追加プレート8とを固定する。 As shown in Figures 6 to 9, the passenger conveyor device of Example 2 is obtained by extending the support angle upper plate 6 of Example 1 and adding an additional plate 8. The additional plate 8 corresponds to the extension member in the claims. The additional plate 8 is provided on the support beam side of the support angle, and the support angle upper plate 6 fixes the support angle and the additional plate 8.

この実施例2の構成によれば、前述した実施例1と同様の効果を得ることができる。また、支持アングルの長さを延長したのと同様に、支持アングルと受梁とのかかり代を増すことができる。支持アングル上面プレート6と固定金具7は、同一線上にないため、支持アングル上面プレート6を延長しても、固定金具7は位置と形状の変更が不要である。 The configuration of this embodiment 2 can achieve the same effect as the above-mentioned embodiment 1. In addition, just as if the length of the support angle was extended, the overlap between the support angle and the support beam can be increased. Because the support angle top plate 6 and the fixing bracket 7 are not on the same line, there is no need to change the position or shape of the fixing bracket 7 even if the support angle top plate 6 is extended.

ここで、本発明に係る乗客コンベア装置の第3の実施の形態を実施例3として図に基づき説明する。なお、前述の実施例で説明した構成要素と同等の構成要素には同一符号を付して説明を適宜省略する。 Here, a third embodiment of the passenger conveyor system according to the present invention will be described as Example 3 with reference to the drawings. Note that components equivalent to those described in the previous examples are given the same reference numerals and descriptions thereof will be omitted as appropriate.

実施例3の乗客コンベア装置は、図10~図14に示すように、実施例1および実施例2において、固定金具7に開口部12と固定金具補強プレート13を追加した構成である。 The passenger conveyor device of Example 3, as shown in Figures 10 to 14, is configured by adding an opening 12 and a fixing bracket reinforcing plate 13 to the fixing bracket 7 in Examples 1 and 2.

既に説明したように、固定金具7は、板状の金属を曲げて形成されることで、支持アングルの上面と対向し且つ本体枠1の長手方向に平行な第1の面と、第1の面と逆側の縁で受梁に取り付けられる第2の面とを有する。 As already explained, the fixing bracket 7 is formed by bending a metal plate, and has a first surface that faces the upper surface of the support angle and is parallel to the longitudinal direction of the main frame 1, and a second surface that is attached to the support beam at the edge opposite the first surface.

開口部12は、固定金具7の第1の面に設けられ、第2の面の表裏で受梁に取り付け加工される。図12及び図13では、固定金具7は、溶接部7aと溶接部7bで受梁に溶接されている。 The opening 12 is provided on the first surface of the fixing bracket 7, and the second surface is attached to the support beam on both sides. In Figures 12 and 13, the fixing bracket 7 is welded to the support beam at welds 7a and 7b.

溶接部7aは、固定金具7の曲がりの外側になるため、前述の実施例と同様に溶接できる。一方、溶接部7bは固定金具7の内側になり、前述の実施例の構成では第1の面に遮蔽されて溶接が困難である。そこで、本実施例3では、第1の面に開口部12を設け、開口部12を通して溶接部7bでの溶接を可能としているのである。 Since the welded portion 7a is on the outside of the bend in the fixing bracket 7, it can be welded in the same way as in the previous embodiment. On the other hand, the welded portion 7b is on the inside of the fixing bracket 7, and in the configuration of the previous embodiment, it is shielded by the first surface and welding is difficult. Therefore, in this embodiment 3, an opening 12 is provided on the first surface, and welding at the welded portion 7b is possible through the opening 12.

固定金具7に開口部12を設けることで固定金具7の強度は低下するが、開口部12を覆う補強部材である固定金具補強プレート13を第1の面に取り付けることで、固定金具7の強度低下を補うことができる。なお、固定金具補強プレート13の取り付けは、溶接などを用いればよい。 Providing an opening 12 in the fixing bracket 7 reduces the strength of the fixing bracket 7, but the reduction in strength of the fixing bracket 7 can be compensated for by attaching a fixing bracket reinforcing plate 13, which is a reinforcing member that covers the opening 12, to the first surface. The fixing bracket reinforcing plate 13 can be attached by welding or the like.

また、固定金具7の第2の面には、切断代14を設けて置き、現地で第1の面の高さを合わせて切断する。受梁の状態を実際に確認し、支持アングルの上面から固定金具7の第1の面までの高さを適正に決定するためである。 The second surface of the fixing bracket 7 is provided with a cutting allowance 14, which is then cut on-site to match the height of the first surface. This is to actually check the condition of the support beam and properly determine the height from the top surface of the support angle to the first surface of the fixing bracket 7.

このように、実施例3によれば、固定金具の固定作業を容易にし、固定金具自体の強度も確保することが可能である。 In this way, according to the third embodiment, it is possible to facilitate the fixing work of the fixing bracket and ensure the strength of the fixing bracket itself.

上述してきたように、実施例に開示した乗客コンベア装置は、建築構造物の一方の受梁と他方の受梁とに架け渡される本体枠1と、前記本体枠の長手方向における両側の終端部にそれぞれ設けられ、前記受梁に載置されて前記本体枠を支持する支持部材である上部支持アングル2及び下部支持アングル3とを備える。 As described above, the passenger conveyor system disclosed in the embodiment comprises a main frame 1 that is spanned between one support beam and the other support beam of an architectural structure, and an upper support angle 2 and a lower support angle 3 that are provided at both longitudinal ends of the main frame and are placed on the support beams to support the main frame.

さらに、乗客コンベア装置は、少なくともいずれかの受梁に取り付けられて支持部材の上面と非接触で対向する面を有する受梁側固定具としての固定金具7と、前記支持部材の上面に取り付けられ、固定金具7に前記本体枠の短手方向の両側から当接する本体枠側固定具としての支持アングル上面プレート6とを備え、前記本体枠1は、前記受梁側固定具が取り付けられた受梁に対して、前記長手方向に摺動可能である。 The passenger conveyor device further includes a fixing bracket 7 as a beam-side fixing device that is attached to at least one of the beams and has a surface that faces the upper surface of the support member without contacting it, and a support angle upper surface plate 6 as a main body frame-side fixing device that is attached to the upper surface of the support member and abuts against the fixing bracket 7 from both sides in the short direction of the main body frame, and the main body frame 1 is slidable in the longitudinal direction relative to the beam to which the beam-side fixing device is attached.

かかる構成では、本体枠載置部において、両端の支持アングルを長手方向で非固定とし、短手方向の固定は支持アングルの中央部上面とすることにより、支持アングルの周囲にスペースを要することなく、受梁から本体枠が脱落せず、短手方向では建築物と衝突することを防止できる。例えば、大地震時において、建築構造物の受梁と、本体枠の支持アングル固定構造の破損を防ぎ、本体枠が建築構造物の受梁から脱落しない。 In this configuration, the support angles at both ends of the main frame mounting section are not fixed in the longitudinal direction, and are fixed in the transverse direction to the upper surface of the center of the support angle, so that no space is required around the support angle, the main frame does not fall off the support beam, and it is possible to prevent collision with the building in the transverse direction. For example, in the event of a major earthquake, damage to the support beam of the building structure and the support angle fixing structure of the main frame is prevented, and the main frame does not fall off the support beam of the building structure.

このように、簡易な構成で脱落や破損を防止する乗客コンベア装置を提供することができる。また、支持アングルの周囲にスペースが不要であるため、既設の乗客コンベア装置を改修して本発明の適用を行うことも容易である。 In this way, it is possible to provide a passenger conveyor system that prevents falling off or damage with a simple configuration. In addition, since no space is required around the support angle, it is easy to apply the present invention to an existing passenger conveyor system by modifying it.

また、開示の乗客コンベア装置は、両方の前記受梁に前記受梁側固定具が取り付けられ、前記支持部材の前記受梁に対するかかり代は、逆側における前記本体枠の端部と前記受梁との隙間よりも大きい。このため、一方の端で本体枠が受梁と衝突しても、他方の端における支持部材の脱落を防止できる。 In addition, in the disclosed passenger conveyor system, the support beam side fixing device is attached to both support beams, and the overlapping margin of the support member on the support beam is larger than the gap between the end of the main body frame and the support beam on the opposite side. Therefore, even if the main body frame collides with the support beam at one end, the support member at the other end can be prevented from falling off.

また、開示の乗客コンベア装置は、前記支持部材の前記受梁側に設けられ、前記かかり代を延長する延長部材をさらに備え、前記本体枠側固定具は、前記支持部材と延長部材とを固定することもできる。すなわち、既設の乗客コンベア装置の支持アングルに延長部材を追加し、かかり代を大きくする改修を容易に行うことができる。また、規格化された支持アングルに対して適用してもよい。 The disclosed passenger conveyor system further includes an extension member that is provided on the support beam side of the support member and extends the overlap, and the main frame side fixing device can also fix the support member and the extension member. In other words, an extension member can be added to the support angle of an existing passenger conveyor system, and modifications can be easily made to increase the overlap. It may also be applied to standardized support angles.

また、開示の乗客コンベア装置は、前記支持部材の上面から前記受梁側固定具までに所定の間隙を設けることで、上下の揺れにより固定金具7が破損する事態を回避できる。 In addition, the disclosed passenger conveyor system provides a predetermined gap between the upper surface of the support member and the beam-side fixing device, thereby preventing the fixing bracket 7 from being damaged by vertical shaking.

また、板状の金属を曲げて固定金具7を形成することで、固定金具7に前記支持部材の上面と対向し且つ前記長手方向に平行な第1の面と、前記第1の面と逆側の縁で前記受梁に取り付けられる第2の面とを設け、前記第1の面に開口部12を設け、前記第2の面の表裏で前記受梁に取り付け加工することで、固定金具7を受梁に強固に取り付けることができる。合わせて、前記開口部を覆って前記第1の面に補強部材を取り付けることで、開口部による固定金具7の強度低下を補うことができる。 In addition, by forming the fixing bracket 7 by bending a metal plate, the fixing bracket 7 is provided with a first surface that faces the upper surface of the support member and is parallel to the longitudinal direction, and a second surface that is attached to the receiving beam at the edge opposite the first surface, and an opening 12 is provided in the first surface, and the front and back of the second surface are attached to the receiving beam, so that the fixing bracket 7 can be firmly attached to the receiving beam. In addition, by covering the opening and attaching a reinforcing member to the first surface, the reduction in strength of the fixing bracket 7 due to the opening can be compensated for.

なお、前述した実施例は本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。また、各実施の形態の構成の一部について、他の構成の追加・削除・置き換えをすることが可能である。 The above-mentioned examples have been described in detail to clearly explain the present invention, and are not necessarily limited to those having all of the configurations described. In addition, it is possible to add, delete, or replace part of the configuration of each embodiment with other configurations.

例えば、前述の実施例では、上部側と下部側の双方で長手方向の摺動を許容する構成を例示したが、一方で長手方向の摺動を許容し、他方では長手方向の固定を行う構成としてもよい。 For example, in the above embodiment, a configuration was exemplified in which longitudinal sliding was permitted on both the upper and lower sides, but a configuration in which longitudinal sliding was permitted on one side and longitudinal fixation was performed on the other side may also be used.

また、前述の実施例では、エスカレータを例示して説明を行ったが、傾斜した斜面を動かして乗客を運搬する構成や、水平方向に乗客を運搬する構成で本発明を実施してもよい。 In addition, in the above embodiment, an escalator was used as an example, but the present invention may also be implemented with a configuration in which passengers are transported by moving an inclined slope, or a configuration in which passengers are transported horizontally.
