Description

  The present invention relates to a passenger conveyor such as an escalator and a moving sidewalk (electric road), and a renewal method of the passenger conveyor.

  The passenger conveyor includes a frame installed in the building structure, and a plurality of steps provided in the frame and connected in an endless manner to circulate. And the flame | frame is installed in the building structure by constructing the both ends of the advancing direction of a step on a building structure.

  Moreover, the passenger conveyor may be renewed by removing the old passenger conveyor that has been aged and installing a kind passenger passenger conveyor at the same location. Also, in recent years, large interlaminar displacement has occurred due to earthquake motion, and even if the distance between the lower floor and upper floor of the building structure, that is, the inter-beam dimension is relatively large, the earthquake resistance is maintained so that the frame does not fall. An excellent passenger conveyor is desired.

  As a technique for improving the earthquake resistance of the passenger conveyor, for example, there is a technique described in Patent Document 1. In this patent document 1, one is attached to the main chord material of the truss frame and the other is placed on the finished floor surface of the building structure to secure a larger allowance than the allowance between the support angle and the building structure. A passenger conveyor with an additional frame is described.

  Japanese Patent Application Laid-Open No. H10-228561 describes that a width direction fastener cover that covers the additional frame is provided in order to restrict the truss frame from moving in the width direction.

JP, 2006-183008, A

  However, in the passenger conveyor described in Patent Document 1, the width direction fastener cover is disposed at the end of the additional frame opposite to the truss frame. Therefore, when a large interlayer displacement occurs due to the earthquake motion, there is a possibility that the width direction fasteners come off from the additional frame.

  In view of the above problems, it is an object of the present invention to provide a passenger conveyor and a passenger conveyor renewal method that can reliably prevent the frame from moving in the width direction even when a large interlayer displacement occurs.

  In order to solve the above problems, the passenger conveyor includes a frame provided in a building structure, a plurality of steps, an existing support angle, a support frame, and a width direction regulating member. The frame is installed in the building structure. The plurality of steps are provided in the frame and connected endlessly so as to circulate and move in the frame. The existing support angles are provided at both ends of the frame in the traveling direction of the plurality of steps, and are placed on a cradle recessed downward in the vertical direction from the finished floor surface of the building structure to support the frame. One end of the support frame is fixed to the frame or the existing support angle, and the other end is placed on the finished floor surface. Further, the support frame has a longer allowance than the allowance placed on the cradle at the existing support angle. The width direction regulating member is disposed outside the support frame in the width direction, and is fixed to the cradle or a member provided on the cradle.

In addition, the renewal method of the passenger conveyor includes a frame installed in the building structure in advance, a plurality of steps provided in the frame and circulating in the frame, and both ends of the frame in the traveling direction of the plurality of steps. In the renewal method of a passenger conveyor provided with an existing support angle placed on a cradle provided in a building structure, the following steps (1) to (2) are included.
(1) A step of attaching a support frame having a longer allowance to the frame or the existing support angle than an allowance placed on the cradle in the existing support angle.
(2) A step of fixing the width direction regulating member to the cradle or a member provided on the cradle on the outer side in the width direction of the support frame.

  According to the passenger conveyor and the passenger conveyor renewal method configured as described above, the frame can be reliably prevented from moving in the width direction even when a large interlayer displacement occurs.

In the building structure 200, a lower cradle 205A is provided on the lower floor 200A, and an upper cradle 205B is provided on the upper floor 200B. Since the lower cradle 205A and the upper cradle 205B have the same configuration, the lower cradle 205A will be described here.

  As shown in FIG. 2, the lower cradle 205A is a stepped surface that is recessed downward in the vertical direction from the finished floor surface 203 of the lower floor 200A. The lower cradle 205A is formed at a corner on the passenger conveyor 1 side of the lower floor 200A. The lower cradle 205A and the upper cradle 205B are, for example, building frames formed by building beams made of concrete or H-shaped steel. The passenger conveyor 1 is installed on the lower cradle 205A and the upper cradle 205B.

[Passenger conveyor]
The passenger conveyor 1 includes a frame 2, a lower floor plate 3A, an upper floor plate 3B, a plurality of steps 5 on which passengers are placed, a pair of balustrade members 6 and 6, and a lower sprocket 7 installed in the building structure 200. And an upper sprocket 8 and a drive unit (not shown). The passenger conveyor 1 includes an existing support angle 9, a support frame 10, and a width direction regulating member 20.

  The frame 2 is installed across the lower floor 200A and the upper floor 200B. The frame 2 includes a lower floor horizontal portion 2A, an upper floor horizontal portion 2B, and an intermediate inclined portion 2C. The lower floor horizontal portion 2A and the upper floor horizontal portion 2B are formed in parallel to each other. The lower floor horizontal portion 2A and the upper floor horizontal portion 2B are portions that are kept parallel to the upper floor 200B and the lower floor 200A in a state where the frame 2 is installed on the building structure 200. .

  The intermediate inclined portion 2C is provided between the lower floor horizontal portion 2A and the upper floor horizontal portion 2B. The intermediate inclined portion 2C is inclined with respect to the lower floor horizontal portion 2A and the upper floor horizontal portion 2B. Hereinafter, the direction extending from the lower floor 200 </ b> A toward the upper floor 200 </ b> B in the frame 2 is a longitudinal direction of the frame 2. In addition, the direction perpendicular to the longitudinal direction and the vertical direction of the frame 2, that is, the left-right direction in the state where the frame 2 is viewed from the lower floor 200 </ b> A is defined as the width direction of the frame 2.

  The lower floor plate 3 </ b> A is arranged on the upper part of the lower floor horizontal part 2 </ b> A in the frame 2. Further, the upper floor plate 3 </ b> B is disposed above the upper floor horizontal portion 2 </ b> B in the frame 2. The lower floor plate 3 </ b> A and the upper floor plate 3 </ b> B serve as entrances and exits for the passenger conveyor 1.

  Further, a lower sprocket 7 is disposed in the lower floor horizontal portion 2A of the frame 2, and an upper sprocket 8 and a drive unit (not shown) are disposed in the upper floor horizontal portion 2B. A transmission chain is wound around the upper sprocket 8 and a drive unit (not shown). And the upper sprocket 8 rotates when a drive part not shown drives. An endless step chain (not shown) is wound around the lower sprocket 7 and the upper sprocket 8. And when the upper sprocket 8 rotates, the lower sprocket 7 and the step chain rotate.

  The plurality of steps 5 are connected endlessly via a step chain (not shown) to form a series of conveyors. The plurality of steps 5 are guided by guide rails attached to the frame 2 and circulate on the forward path side and the return path side. Passengers are transported on the steps 5 moving on the outward path side.

Next, the balustrade member 6 will be described.
The pair of balustrade members 6, 6 are supported on the upper portion of the frame 2 and are disposed on both sides of the frame 2 in the width direction.

  The balustrade member 6 includes a flat panel member 21, a deck portion 22, and a moving handrail 23. The deck portion 22 is fixed to the frame 2. The deck portion 22 is disposed along the longitudinal direction of the frame 2. The deck portion 22 supports the panel member 21. A moving handrail 23 is provided on the periphery of the panel member 21.

  The moving handrail 23 is composed of an endless belt member. The movable handrail 23 is supported by the panel member 21 so as to be movable. Further, the moving handrail 23 circulates in synchronization with the circulation movement of the plurality of steps 5.

  As shown in FIGS. 2 and 3, the frame 2 is constituted by a truss structure, for example. The frame 2 is configured by a truss structure having a lower frame, an upper frame facing the lower frame, and a vertical frame connecting the lower frame and the upper frame.

  Moreover, as shown in FIG. 1, the existing support angle 9 and the support frame 10 are attached to the both ends of the longitudinal direction of the flame | frame 2. As shown in FIG.

[Existing support angle]
As shown in FIG. 2, the existing support angle 9 is formed in a substantially L shape when viewed from the extending direction. The existing support angle 9 is fixed to the upper end in the vertical direction at both ends in the longitudinal direction of the frame 2.

  The existing support angle 9 has a fixed piece 11 and a support piece 12. The support piece 12 is bent substantially continuously from one end of the fixed piece 11 and is continuous.

  The fixed piece 11 is fixed to the end of the frame 2 in the longitudinal direction by welding. Thereby, the fixed piece 11 becomes substantially parallel to the vertical direction, and the support piece 12 becomes substantially parallel to the horizontal direction. Then, the support piece 12 of the existing support angle 9 fixed to the lower floor 200 </ b> A side protrudes from the frame 2 toward the lower floor 200 </ b> A of the building structure 200. Further, the support piece 12 of the existing support angle 9 fixed to the upper floor 200B side protrudes from the frame 2 toward the upper floor 200B of the building structure 200.

  Further, the support piece 12 provided on the lower floor 200A side is placed on the lower cradle 205A via the existing adjustment plate 14. The support piece 12 and the lower cradle 205 may be fixed to be a fixed end, or the support piece 12 and the lower cradle 205 may be fixed to each other as a free end. Similarly, as shown in FIG. 1, the support piece 12 provided on the upper floor 200B side is placed on the upper cradle 205B via an existing adjustment plate (not shown).

  Here, the length L1 from the wall surface 204 of the lower floor 200A to the end of the support piece 12 on the side opposite to the fixed piece 11, that is, the front end is the existing hook allowance.

[Support frame]
Next, the support frame 10 will be described.
As shown in FIGS. 2 and 3, two support frames 10 are arranged at both ends in the longitudinal direction of the frame 2. Further, the support frame 10 is disposed at both ends in the width direction of the frame 2 so as to sandwich the lower floor plate 3A from both sides in the width direction.

  The support frame 10 is formed in a substantially rectangular parallelepiped shape, for example. One end of the support frame 10 in the longitudinal direction is arranged on the upper end of the frame 2 in the vertical direction, that is, on the upper surface of the upper frame constituting the frame 2. The other end portion of the support frame 10 in the longitudinal direction, that is, the tip end portion of the support frame 10 protrudes from the end portion of the frame 2 in the longitudinal direction toward the building structure 200. And the protrusion length from the frame 2 in the support frame 10 is set longer than the length from the fixed piece 11 to the front-end | tip part in the support piece 12 of the existing support angle 9. FIG.

  Further, the portion of the support frame 10 that protrudes from the frame 2 is placed on the upper surface in the vertical direction of the support piece 12 of the existing support angle 9. The support frame 10 is fixed to the support piece 12 of the existing support angle 9 by fixing bolts 16. Further, the front end portion of the support frame 10 is placed on the finished floor surface 203.

  Here, the finished floor 203 is disposed above the support piece 12 of the existing support angle 9 placed on the lower cradle 205 </ b> A in the vertical direction. Therefore, a notch 10e is formed at the lower end of the support frame 10 in the vertical direction of the support frame 10.

  The length L2 from the wall surface 204 of the lower floor 200A to the tip of the support frame 10 is set to be longer than the length L1 of the existing hanging allowance (L1 <L2). For this reason, the length of the support allowance of the support frame 10 is longer than the existing allowance of the existing support angle 9. Thereby, the length of the allowance with the building structure 200 in the passenger conveyor 1 can be extended compared with the case where only the existing support angle 9 is provided. As a result, it is possible to prevent the frame 2 from falling from the building structure 200 even when a large interlayer displacement angle is generated by the earthquake motion and the dimension between the lower floor 200A and the upper floor 200B is relatively large. .

  The support frame 10 having the above-described configuration is also attached to the upper floor 200B in the frame 2.

[Width direction regulating member]
Next, the width direction regulating member 20 will be described.
As shown in FIGS. 2 and 3, the width direction regulating member 20 is formed in a substantially flat plate shape. The width direction regulating member 20 is disposed at a position facing the other surface 10 b opposite to the one surface 10 a facing the lower floor plate 3 </ b> A in the support frame 10, that is, outside the support frame 10. The width direction regulating member 20 is fixed to the lower cradle 205A by welding, for example, when the lower cradle 205A is formed of an H-type steel material.

  The vertical length T2 from the lower cradle 205A to the upper end 20a of the width direction regulating member 20 is set longer than the length T1 from the lower cradle 205A to the finished floor 203 on which the support frame 10 is placed. (T1 <T2). Therefore, the upper end portion 20 a of the width direction regulating member 20 protrudes upward in the vertical direction from the lower surface 10 c of the distal end portion of the support frame 10 placed on the finished floor surface 203. Therefore, the width direction regulating member 20 faces the other surface 10 b of the support frame 10.

  Further, the width direction regulating member 20 having the above-described configuration is also provided on the upper cradle 205B on the upper floor 200B of the building structure 200.

  In addition, although the example which mounts the front-end | tip part of the support frame 10 in the finishing floor surface 203 was demonstrated in this example, it is not limited to this. For example, an accommodation part may be provided on the finished floor 203 and a part or all of the tip of the support frame 10 may be accommodated in this accommodation part. Thereby, the amount by which the support frame 10 protrudes upward in the vertical direction from the finished floor surface 203 of the lower floor 200A can be reduced. As a result, the beauty of the passenger conveyor 1 can be prevented from being lowered by the support frame 10.

1-2. Passenger Conveyor Renewal Method Next, a passenger conveyor renewal method having the above-described configuration will be described.
As shown in FIGS. 1 and 2, an existing support angle 9 is fixed to the frame 2 of the passenger conveyor 1 in advance. First, the support frame 10 is fixed to the upper surface of the frame 2 or the support piece 12 of the existing support angle 9 using, for example, fixing bolts 16, and the front end portion of the support frame 10 is placed on the finished floor surface 203. By using the fixing bolt 16, the support frame 10 can be easily attached to the existing frame 2 and the existing support angle 9 where it is difficult to perform the welding operation.

  Next, the width direction regulating member 20 is fixed to the lower cradle 205A by, for example, welding. As shown in FIG. 3, the width direction regulating member 20 is fixed to the outer side in the width direction than the support frame 10. Thereby, the width direction regulating member 20 faces the other surface 10 b of the support frame 10.

  Further, the above-described operation is similarly performed on the upper floor 200B. Thereby, the renewal work of the passenger conveyor 1 is completed. In addition, the process concerning the renewal of the passenger conveyor 1 is not limited to the above-described order, and the support frame 10 may be fixed after fixing the width direction regulating member 20.

  By the renewal method of the passenger conveyor 1 described above, the allowance between the passenger conveyor 1 and the building structure 200 can be extended with a simple structure. As a result, it is possible to provide a passenger conveyor that is improved in earthquake resistance in a short time and at a low cost. In particular, it is possible to prevent the frame 2 from falling from the building structure 200 even when a large interlayer displacement occurs due to seismic motion and the dimension between the lower floor 200A and the upper floor 200B extends relatively large.

  Further, by fixing the width direction regulating member 20 to the outside of the support frame 10, it is possible to prevent the support frame 10 and the frame 2 from moving in the width direction. Further, the width direction regulating member 20 is fixed to a lower cradle 205 </ b> A that is a base from which the support frame 10 protrudes from the frame 2. Further, as described above, the upper end portion 20 a of the width direction regulating member 20 protrudes upward in the vertical direction from the lower surface 10 c of the front end portion of the support frame 10.

  Accordingly, even when a relatively large interlayer displacement is caused by the earthquake motion and the dimension between the lower floor 200A and the upper floor 200B is relatively large, the width direction regulating member 20 is reliably opposed to the support frame 10. be able to. As a result, it is possible not only to prevent the frame 2 from falling, but also to reliably prevent the frame 2 and the support frame 10 from moving in the width direction, thereby providing a passenger conveyor having excellent earthquake resistance. be able to.

  Further, when the width direction regulating member 20 is fixed to the finished floor surface 203, fixing places such as fixing bolts and welding for fixing the width direction regulating member 20 are exposed on the finished floor surface 203, and the finished floor surface 203 is exposed. The aesthetics of the fall. On the other hand, in this example, the width direction regulating member 20 is fixed to the cradle 205A, 205B instead of the finished floor 203. Thereby, it is possible to prevent the appearance of the finished floor surface 203 from being lowered by the width direction regulating member 20.

1-3. Next, another example of the fixing method of the width direction regulating member will be described with reference to FIG.
FIG. 4 is a cross-sectional view showing another example of the fixing method of the width direction regulating member.

  In the embodiment described above, the example in which the width direction regulating member 20 is fixed to the lower cradle 205A and the upper cradle 205B has been described, but the present invention is not limited to this. For example, as shown in FIG. 4, the width direction regulating member 20 may be fixed to the existing adjustment plate 14 placed on the lower cradle 205A. Thereby, even when it is difficult to fix to the cradle 205A, 205B, the width direction regulating member 20 can be fixed.

2. Second Embodiment Next, a second embodiment of a support structure for a passenger conveyor and a building structure will be described with reference to FIG.
FIG. 5: is sectional drawing which shows the support structure of the passenger conveyor and building structure concerning 2nd Example.

  The difference between the passenger conveyor according to the second embodiment and the passenger conveyor according to the first embodiment is the configuration of the width direction regulating member. Therefore, here, the configuration of the width direction restricting member will be described, and portions common to the passenger conveyor according to the first embodiment will be denoted by the same reference numerals and redundant description will be omitted. Since the support structure of the passenger conveyor is the same for the lower floor 200A and the upper floor 200B, the support structure for the lower floor 200A will be described here.

  As shown in FIG. 5, the width direction regulating member 30 includes a regulating piece 31 and a fixed piece 32. The restricting piece 31 is erected substantially vertically from the fixed piece 32. The fixing piece 32 is fixed to the lower cradle 205 </ b> A via the fixing bolt 35. The restricting piece 31 faces the other surface 10 b of the support frame 10.

  In this way, by fixing the width direction regulating member 30 to the lower cradle 205A via the fixing bolt 35, when the lower cradle 205A cannot be welded as in the case where the lower cradle 205A is formed of concrete, welding work can be performed. The width-direction regulating member 30 can be easily fixed at a place that is difficult to perform. Also in the width direction regulating member 30 according to the second embodiment, the width direction regulating member 30 is attached to the existing adjustment plate 14 placed on the lower cradle 205A, similarly to the fixed portion shown in FIG. It may be fixed.

  Since the other structure is the same as that of the passenger conveyor 1 concerning the example of 1st Embodiment mentioned above, those description is abbreviate | omitted. Even in the passenger conveyor to which the width direction regulating member 30 having such a configuration is attached, the same operation and effect as the passenger conveyor 1 according to the first embodiment described above can be obtained.

3. Third Embodiment Next, a third embodiment of a support structure for a passenger conveyor and a building structure will be described with reference to FIG.
FIG. 6 is a side view showing a support structure for a passenger conveyor and a building structure according to the third embodiment.

  The difference between the passenger conveyor according to the third embodiment and the passenger conveyor according to the first embodiment is the configuration of the width direction regulating member. Therefore, here, the configuration of the width direction restricting member will be described, and portions common to the passenger conveyor according to the first embodiment will be denoted by the same reference numerals and redundant description will be omitted. Since the support structure of the passenger conveyor is the same for the lower floor 200A and the upper floor 200B, the support structure for the lower floor 200A will be described here.

  As shown in FIG. 6, the width direction regulating member 40 is formed in a substantially flat plate shape. The width direction regulating member 40 is fixed to the lower cradle 205A. Further, the width direction regulating member 40 is fixed to the lower cradle 205A, and extends in a direction away from the finished floor surface 203, that is, toward the frame 2 by a predetermined length.

  The length S2 of the width direction regulating member 40 in the direction from the lower cradle 205A toward the frame 2 is set to be longer than at least the length S1 placed on the finished floor surface 203 of the support frame 10 ( S1 <S2). Therefore, even when the dimension between the lower floor 200 </ b> A and the upper floor 200 </ b> B is relatively large due to the earthquake motion, the width direction regulating member 40 can be reliably opposed to the support frame 10.

  The vertical length T3 from the lower cradle 205A to the upper end 40a of the width direction regulating member 40 is set shorter than the length T1 from the lower cradle 205A to the finished floor 203 on which the support frame 10 is placed. (T1> T2). Therefore, the upper end portion 40a of the width direction restricting member 40 is disposed below the finished floor surface 203 in the vertical direction. As a result, the width direction restricting member 40 does not protrude from the finished floor surface 203. It can prevent that the beauty | look of the conveyor 1 falls by the width direction control member 40. FIG.

  Since the other structure is the same as that of the passenger conveyor 1 concerning the example of 1st Embodiment mentioned above, those description is abbreviate | omitted. Even in the passenger conveyor to which the width direction regulating member 40 having such a configuration is attached, the same operations and effects as those of the passenger conveyor 1 according to the above-described first embodiment can be obtained.

  It should be noted that the present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the spirit of the invention described in the claims.

  In the above-described embodiment, the escalator in which a step is generated between the steps is described as an example of the inclined type passenger conveyor. However, the passenger conveyor of the present invention has a plurality of steps in which no step is generated between the steps. It can also be applied to electric roads, so-called moving sidewalks.

  The present invention can also be applied to a passenger conveyor having a frame in which at least a part of the intermediate inclined portion 2C is provided with a portion parallel to the lower floor horizontal portion 2A and the upper floor horizontal portion 2B. Furthermore, the present invention is similarly applied to a passenger conveyor having a frame in which the extending direction of the lower floor horizontal part 2A and the upper floor horizontal part 2B is different by changing the extending direction of the intermediate inclined part 2C. Is applicable.

  In the above-described embodiment, the example in which the support frame is fixed to the support angle has been described. However, the present invention is not limited to this. For example, the support frame may be fixed to the upper frame of the frame, or the support frame is configured by an L-shaped member bent substantially vertically, and the support frame is a vertical frame that connects the upper frame and the lower frame of the frame. It may be fixed.

  Further, a handrail, a display unit that indicates the traveling direction of the step, or the like may be provided on the support frame.
