Description

  The present invention relates to a passenger conveyor including an escalator, a moving walkway, and the like, and more particularly to a passenger conveyor that can cope with interlayer displacement of buildings due to ground vibration and shaking between two buildings, and particularly relates to a floor structure thereof.

  Generally, when an earthquake occurs, the building shakes, and the passenger conveyor installed between the lower floor and the upper floor is also shaken together. Depending on the structure of the building, the lower floor and the upper floor have different shaking magnitudes, so that the support part of the passenger conveyor slides, a gap is formed on the floor surface, and the main body frame is plastically deformed. In order to cope with this, there is an example in which a passenger conveyor is provided with a slidable floor as disclosed in JP 2001-158585 A (Patent Document 1).

  In the passenger conveyor of Patent Document 1, a fixed side portion that fixes the upper end portion of the main body frame in an immovable manner to the building structure, and an end portion edge portion of the lower portion of the main body frame is built. A mounting side portion that is placed on the body, and has a space that allows movement of the main body frame in the longitudinal direction between the main body frame and the building structure on which the mounting side portion is located. A sliding part that can follow only in the longitudinal direction is provided on the mounting side part against a positional shift between the building structure and the longitudinal movement, and the collision force between the main body frame and the building structure is absorbed. Buffering means are provided.

Japanese Patent Laid-Open No. 2001-158585

  The floor on the support part (sliding part) of the passenger conveyor of Patent Document 1 is fixed with one end of the floor to the support part of the passenger conveyor by welding or the like in order to absorb the interlayer displacement of the building, and the other end is not fixed. It slides on the floor on the building side. The floor is composed of a floor plate and a reinforcing material (receiving material) that supports the floor plate.

  However, in the case of the configuration of Patent Document 1, if an attempt is made to cope with the case where the interlayer displacement between the upper and lower floors is large, a large gap (space between the reinforcing material (receiving material) and the building structure) is secured (long). There is a need to. If the gap is large (long), the floor plate needs to be lengthened and the floor plate is easily bent. Therefore, the floor plate needs to be thick to prevent the deflection. However, when the floor plate is made thick, there is a problem that a large step is generated on the walking surface of the user due to the thickness of the floor plate placed on the floor on the building side.

  An object of the present invention is a configuration including a slide floor that slides on a floor on a building side in order to cope with a relative displacement between two entrances and exits of a passenger conveyor, including interlayer displacement between upper and lower floors. An object of the present invention is to provide a passenger conveyor that can cope with a case where a relative displacement between two entrances / exit gates is large, and that has a small step due to a floor plate constituting a slide floor.

  In order to achieve the above-mentioned object, the present invention includes a main body frame that is supported at both ends by a stepped portion provided on a floor of a building, and at least one end of the main body frame is located with respect to the stepped portion. It is supported so as to be relatively displaceable in the longitudinal direction of the main body frame, and is disposed between a floor constructed on the main body frame side and a floor on the building side, and is slidable with respect to the floor on the building side In the passenger conveyor having a slide floor provided in, the slide floor includes a surface plate that becomes a walking surface of a user, and a reinforcing structure that is installed in the stepped portion and supports the back surface of the surface plate, The reinforcing structure is arranged in the longitudinal direction of the main body frame so as to have a first gap between the main body frame side and a second gap between the stepped portion and the step surface side, The main body frame is relatively displaced in the longitudinal direction with respect to the stepped portion. If that, the installed movably pressing force receiving by the stepped portion upper from the body frame side.

  In a configuration with a sliding floor that slides on the floor on the building side to accommodate relative displacement between the two entrances of the passenger conveyor, including upper and lower interlayer displacement, relative to the two entrances It is possible to provide a passenger conveyor that can cope with a large displacement and has a small step due to the surface plate constituting the slide floor.

  Problems, configurations, and effects other than those described above will be clarified by the following description of embodiments.

  Hereinafter, an embodiment of a passenger conveyor according to the present invention will be described with reference to the drawings.

  A first embodiment according to the present invention will be described with reference to FIGS. 1 to 4C.

  The structure of the passenger conveyor 1 of a present Example is demonstrated based on FIG. 1 thru | or FIG. FIG. 1 is an overall view of a passenger conveyor 1 that spans between a lower-floor building 2 and an upper-floor building 3. FIG. 2 is a view showing a floor cross section of the passenger conveyor 1, and is a view showing a normal state. FIG. 3 is a floor plan view of the passenger conveyor 1. Note that the floor plan view of FIG. 3 is also applied to floor planes of second and third embodiments described later.

  The passenger conveyor 1 described in this specification is an escalator that is built between different floors of a structure (also referred to as a structure) including a building (building), or between two different structures with a horizontal or gentle inclination. The target is a moving sidewalk. The floor of the present invention (hereinafter referred to as a slide floor) is provided at one or both of the lower floor building 2 and the upper floor building 3, that is, at least one of the two entrances of the passenger conveyor 1. In this embodiment, an example in which a slide floor is installed on the lower floor side of an escalator will be described.

  In moving walkways installed with escalators and gentle slopes, interlayer displacement occurs between the lower-floor building 2 and the upper-floor building 3 due to vibration during an earthquake. When a moving sidewalk is installed in a horizontal direction and is installed between two different structures, a relative displacement occurs between the two entrances of the moving sidewalk. In the present specification, the relative displacement and the interlayer displacement are described as a displacement parallel to the horizontal direction along the longitudinal direction of the frame (frame body) 13 (the travel direction of the step). In addition, the relative displacement between the two entrances is used as a superordinate concept including inter-layer displacement in a moving sidewalk that is installed with an escalator and a gentle slope.

  As shown in FIG. 1, the passenger conveyor 1 has an upper entrance which is the other entrance that is connected to the floor F <b> 2 of the upper building 3 from the lower entrance 102 that is one entrance to the floor F <b> 1 of the lower building 2. A step 104 connected endlessly and circulated through 103, a handrail 105 moving in synchronization with this step 104, and standing on both sides in the width direction of the step 104, form a travel path of the handrail 105. Structural parts such as balustrade 106 are provided. In the present specification, the width direction of the step 104 is a direction perpendicular to the moving direction of the step 104 and parallel to the tread surface of the step 104 (horizontal direction), along the moving direction of the step 104, A direction parallel to the tread surface of the step 104 is defined as a depth direction. This depth direction may be referred to as a frame (also referred to as a main body frame) 13 described later or the longitudinal direction of the passenger conveyor 1.

  In addition, the longitudinal direction of the structural parts such as the balustrade 106, that is, the frame 13 having the total length L from the lower entrance 102 to the upper entrance 103 via the lower curved path 104A, the inclined path 104B, and the upper curved path 104C The portion 107A, the inclined portion 107B, and the upper horizontal portion 107C are connected and arranged between the floor F1 of the lower floor building 2 and the floor F2 of the upper floor building 3. The frame 13 is made of, for example, a steel material.

  The support portion (also called a beam) 7 fixed to the upper side (floor F2 side) end of the frame 13 is firmly integrated with the building structure 108 on the upper side so that it cannot move and cannot be detached. This forms a fixed side portion 101A of the frame 13. In addition, a support portion (also referred to as a beam) 7 fixed to an end portion on the lower side (floor F1 side) of the frame 13 is placed in an unfixed state with respect to the floor F1 of the lower floor building 2, and the frame 13 The mounting side portion 101B is formed. The loading side 101B has a stepped portion (also called a receiving beam) that is a building structure on the frame 13 and the floor F1 side due to a large interlayer displacement (relative displacement) between the floor F1 and the floor F2 due to an earthquake or the like. ) When relative displacement occurs between 2A and 2A, it is configured to be prevented from falling off the stepped portion 2A of the floor F1. Further, by providing the placement side portion 101B, it is possible to prevent the force in the compression direction from being applied to the frame 13, or to reduce the force. For this purpose, the placement side portion 101B includes a sliding portion 100 that slides with respect to the stepped portion 2A on the floor F1 side.

  Next, the configuration of the placement side portion 101B will be described with reference to FIGS.

  There is a main floor 4 on the frame 13, a first floor 5 on the support 7 of the passenger conveyor 1, and a second floor 5 a is installed in the stepped portion 2 A of the lower building 2.

  The support portion 7 is made of L-shaped steel, the vertical side 7v of the L-shaped steel is fixed to the end of the frame 13, and the horizontal side 7h of the L-shaped steel is not relative to the lower floor building 2. In a fixed state, it is placed on the stepped portion 2A via a bispi 17. With this configuration, the support portion 7 constitutes a sliding portion 100 for the second floor 5a constituting the slide floor to slide relative to the lower floor building 2. A gap 12 is formed between the support portion 7 and the end surface 2A2 on the frame 13 side of the stepped portion 2A. When an interlayer displacement (relative displacement) occurs between the floor F1 and the floor F2, the placement side The portion 101B can be displaced by sliding to the floor 14 (same as the floor F1) side of the lower floor building 2 within the gap 12 with respect to the stepped portion 2A. The bispi 17 is an installation height adjusting member for adjusting the installation height of the support portion 7.

  As described above, the passenger conveyor in the present embodiment includes the frame 13 whose both ends are supported by the stepped portion 2A provided on the floor of the building, and at least one end portion of the frame 13 is the placement side portion 101B. And is supported so as to be relatively displaceable in the longitudinal direction of the frame 13 with respect to the stepped portion 2A.

  The upper surface of the first floor 5 is covered with a first floor plate 8a, and the surface (upper surface) of the first floor plate 8a is a user's walking surface. The first floor 5 and the first floor plate 8a are displaced (slid) with respect to the stepped portion 2A together with the frame 13 along with the interlayer displacement during the earthquake.

  In the present embodiment, the first floor 5 configured on the frame 13 side and the floor 14 of the lower-floor building 2 which is the floor on the building side are provided and slidable with respect to the floor 14. And a second floor (slide floor) 5a.

  The second floor 5 a includes a second floor plate (also referred to as a surface plate) 8 b and a reinforcing structure 20. The reinforcing structure 20 includes a floor reinforcing portion 6 and a guide assembly 30, and is installed on the stepped portion 2A to support the back surface of the second floor plate 8b. The second floor plate 8b and the floor reinforcing portion 6 are fixed and integrated with each other (integrated structure), and the floor reinforcing portion 6 is supported by the guide assembly 30. The guide assembly 30 includes a guide 30a that holds the floor reinforcing portion 6, and a base 30b on which the guide 30a is mounted and fixed. The guides 30a are disposed on both sides of the floor reinforcing portion 6 in the longitudinal direction of the frame 13, and are fixed to the base 30b with bolts 30d.

  The floor reinforcing portion 6 is disposed near the center of the back surface of the second floor plate 8b in order to support the second floor plate 8b and suppress deflection. The reinforcing structure 20 is arranged in the longitudinal direction of the frame 13 so as to have a first gap 9 between the frame 13 side and a second gap 9a between the stepped portion 2A and the step surface 2A1 side. Has been. Specifically, in the longitudinal direction of the frame 13, gaps are provided on both sides of the floor reinforcing portion 6, and the first gap 9 is between the floor reinforcing portion 6 and the support portion 7 or the first floor 5. The second gap 9a is provided between the floor reinforcing portion 6 and the step surface 2a1 of the stepped portion 2A. As a result, when the frame 13 is displaced relative to the stepped portion 2A in the longitudinal direction of the frame 13, the reinforcing structure 20 is installed so as to be movable on the stepped portion 2A by receiving a pressing force from the frame 13 side. The

  Moreover, the 2nd floor plate 8b was made to overlap on the surface of the 1st floor plate 8a which is the floor comprised on the flame | frame 13 side, as shown in FIG. . The second floor plate 8b is slidable in both directions on the floor 14 side and the first floor plate 8a side. The width where the second floor plate 8b overlaps the floor 14 is B, and the width where the second floor plate 8b overlaps the first floor plate 8a is A.

  In addition, the frictional force (first frictional force) at the contact portion between the back surface of the second floor plate 8b and the surface of the first floor plate 8a is the friction at the portion where the lower surface of the base 30b is in contact with the stepped portion 2A. Pushing force that the support part 7 or the first floor 5 pushes the reinforcing structure 20 when the displacement between the layers is smaller than the force (second friction force) and the second friction force causes an interlayer displacement during an earthquake. (Pressing force) should be larger.

  When an earthquake or the like occurs and the magnitude of the swing is small, when the loading side portion 101B moves in the direction indicated by the arrow Y in FIG. 2, the support portion 7 of the passenger conveyor 1 or the first floor 5 is displaced between layers. Move the first gap 9 by that amount. In this case, since the first frictional force is smaller than the second frictional force, first, the second floor 5a does not move, and the first gap 9 between the first floor 5 and the second floor 5a becomes small. In addition, when a larger-scale swing occurs and an interlayer displacement larger than the first gap 9 occurs, the first floor 5 further moves beyond the first gap 9, so that the passenger conveyor 1 The support portion 7 or the first floor 5 pushes the floor reinforcing portion 6 of the second floor 5a. As a result, the second floor 5a including the second floor plate 8b moves in the longitudinal direction of the frame 13 toward the second gap 9a, and the second gap 9a becomes smaller. Note that the slide surface formed on the second floor 5a is the lower surface of the base 30b.

  As described above, since the floor reinforcing part 6 is arranged near the center of the back surface of the second floor plate 8b and a gap is provided on both sides, it is possible to cope with the interlayer displacement of the building without breaking the floor. I can do it. In addition, since the distance that the loading side portion 101B of the passenger conveyor 1 can slide can be increased, it is possible to cope with large shaking without damaging structural components such as the frame 13.

  In addition, when the reinforcing structure 20 is provided on the back side of the floor plate so as to have the first gap 9 and the second gap 9a on both sides, it is supported only by the end of the second floor plate 8b. In comparison, since the deflection of the second floor plate 8b can be suppressed, the thickness of the second floor plate 8b can be reduced, so that the step at the end of the floor plate can be reduced. Further, in order to lengthen the slidable distance of the loading side portion 101B, the floor plate is moved vertically even if the length of the floor plate (particularly the second floor plate 8b) in the longitudinal direction of the frame 13 is increased. It can prevent bending.

  Next, the operation of the second floor 5a will be described with reference to FIGS. 2 and 4A to 4C. In the present embodiment, since the second floor plate 8b is integrated with the reinforcing structure 20, the second floor plate 8b moves integrally with the reinforcing structure 20.

As shown in FIG. 2, in a normal time when no interlayer displacement occurs, the second floor plate 8b of the second floor 5a is replaced with the first floor 5 or the first floor plate 8a (hereinafter simply referred to as the first floor plate 8a). The length A overlapping with the floor 5 side of the second floor plate 8b is such that the second floor plate 8b has at least the largest possible interlayer displacement (relative displacement) γmax in the longitudinal direction of the frame 13 and the second gap 9a. It is larger than the sum of the size. Specifically, it is set based on Equation 1 so as to have a margin α.
A = second gap 9a + interlayer displacement γmax + margin α (Equation 1)
The length B at which the second floor plate 8 b overlaps the floor 14 of the lower floor building 2 in the longitudinal direction of the frame 13 is at least larger than the first gap 9. Specifically, it is set based on Equation 2 so as to have a margin α. The margin α in Equation 1 may be different from the margin α in Equation 2.
B = first gap 9 + margin α (Equation 2)
The length A is set in consideration of the operation of FIGS. 4A and 4B described below. Regarding the length B, the first gap is taken into consideration when the user walks on the second floor plate 8b and the second floor plate 8b is displaced to the frame 13 side. A length of 9 has been added.

  FIG. 4A is a diagram for explaining the operation of the second floor 5a. The reinforcing structure 20 is pressed against the first floor 5 and the second gap 9a is moved in the direction indicated by the arrow Y from the normal state shown in FIG. It is a figure which shows the state which moved. In this case, it is assumed that an interlayer displacement corresponding to the assumed maximum interlayer displacement γmax has occurred.

  When the frame 13 moves to the stepped surface 2A1 side, the contact portion (the main body floor 5 or the support portion 7) to the reinforcing structure 20 provided on the frame 13 moves through the first gap 9 to reinforce the reinforcing structure 20. When the abutting portion abuts against the reinforcing structure 20, the reinforcing structure 20 receives the pressing force from the frame 13 side and moves to the second gap 9a side.

  In the state shown in FIG. 4A, the gaps (the first gap 9 and the second gap 9a) on both sides of the reinforcing structure 20 are eliminated. The length A1 at which the second floor plate 8b overlaps the first floor 5 side is larger than A by the length of the first gap 9. In addition, the length B1 where the second floor plate 8b overlaps the floor 14 of the lower floor building 2 is increased by the length of the second gap 9a.

  FIG. 4B is a diagram for explaining the operation of the second floor 5a. The first floor 5 and the frame 13 are moved in the opposite direction (direction indicated by the arrow Z) from the state of FIG. It is a figure which shows the state which moved only by the assumed largest interlayer displacement (gamma) max. At this time, the reinforcing structure 20 maintains the position in the state of FIG. 4A. Therefore, an interval corresponding to the sum of the first gap 9, the second gap 9a, and the interlayer displacement γmax is formed between the reinforcing structure 20 and the first floor 5. The length A2 where the second floor plate 8b overlaps the first floor 5 side is only a margin α. However, by setting the overlapping length A in the normal state as shown in FIG. 2 and Equation 1, the maximum displacement from the floor 14 of the lower building 2 is maximized due to the maximum interlayer displacement γmax assumed for the frame 13 and the first floor 5. Even in the state of FIG. 4B that is far away, an overlap length A2 corresponding to the margin α can be left between the second floor plate 8b and the first floor 5 side.

  In this state, the second floor plate 8b is easily bent, but such a state is limited to an emergency such as an earthquake, and this state rarely continues. After that, the maintenance worker or the like may move the second floor 5a so as to have the second gap 9a as shown in FIG. Alternatively, it may be moved so that the second gap 9a is automatically formed by providing an elastic member such as a spring.

  FIG. 4C is a diagram for explaining the operation of the second floor 5a. In the normal state shown in FIG. 2, the first floor 5 expands the first gap 9 by the interlayer displacement γ (indicated by the arrow Z). It is a figure which shows the state which moved to (direction). In this case, an interval corresponding to the sum of the first gap 9 and the interlayer displacement γmax is formed between the reinforcing structure 20 and the first floor 5. The length A3 where the second floor plate 8b overlaps the first floor 5 side is the length corresponding to the sum of the second gap 9a and the margin α, the length of the interlayer displacement γmax being reduced. It will be. Also in this case, the overlap length A3 can be left between the second floor plate 8b and the first floor 5 side.

  The first gap 9, the second gap 9 a, and the above-described gap 12 are determined in consideration of the assumed maximum interlayer displacement γmax (length). That is, the total length of the first gap 9 and the second gap 9a and the size of the gap 12 are preferably equal to or greater than the maximum possible interlayer displacement (relative displacement) γmax. By making the total length of the first gap 9 and the second gap 9a and the gap 12 as described above, the displacement of the placement side portion 101B of the frame 13 is not hindered, and the passenger conveyor 1 and the building side No more damage. As described above, the total length of the first gap 9 and the second gap 9a is made equal to the assumed maximum interlayer displacement γmax and the size of the gap 12, or from the interlayer displacement γmax and the gap 12 Is also increased, the passenger conveyor 1 and the building side are not damaged.

For the length B where the second floor plate 8b overlaps the floor 14 on the lower floor building 2 side, the reinforcing structure 20 is further displaced to the first floor 5 side by a length corresponding to the interlayer displacement γmax. In consideration of the case, it may be set as follows.
B = first gap 9 + interlayer displacement γmax + margin α (Equation 3)
Thereby, it is possible to reliably prevent a gap from being generated between the second floor plate 8b and the floor 14 on the lower floor building 2 side.

  Alternatively, the first floor 5 may not be provided, and the main body floor 4 may be extended so that the main body floor 4 also serves as the first floor 5.

  A second embodiment according to the present invention will be described with reference to FIGS. FIG. 5 is a diagram showing a floor cross section of the passenger conveyor 1. FIG. 6 is a diagram for explaining the operation of the second floor 5a in the present embodiment. The first floor 5 has the first gap 9 due to the maximum interlayer displacement γmax assumed from the normal state shown in FIG. It is a figure which shows the state which moved to the direction (direction shown by arrow Z) which expands.

  In this structure, the second floor plate 8b and the floor reinforcing portion 6 are not an integral structure, and the second floor plate 8b is configured to be relatively displaceable with respect to the floor reinforcing portion 6. The reinforcing structure 20 is composed of the floor reinforcing portion 6, and the guide assembly 30 in the first embodiment is not provided. The floor reinforcing portion 6 is fixed to the stepped portion 2A with bolts 16. Fixing with the bolts 16 is performed in order to prevent displacement of the floor reinforcing portion 6. By fixing with the bolt 16, until the support portion 7 of the passenger conveyor 1 or the first floor 5 collides with the floor reinforcement portion 6 of the second floor 5 a and the floor reinforcement portion 6 is pushed and the bolt 16 is cut. The floor reinforcing part 6 maintains a predetermined position.

  The second floor plate 8b is fixed to the first floor plate 8a with screws 18. Thus, when the first floor 5 moves in the longitudinal direction, the second floor plate 8b moves together with the first floor 5. Alternatively, instead of providing the second floor plate 8b, the first floor plate 8a of the first floor 5 may be extended to the floor 14 of the lower floor building 2.

  In FIG. 5, when the first floor 5 moves in the direction indicated by the arrow Y, the support portion 7 of the passenger conveyor 1 or the first floor 5 moves through the first gap 9 by the interlayer displacement γ. When the interlayer displacement γ is larger than the first gap 9, the support part 7 of the passenger conveyor or the first floor 5 pushes the reinforcing part 6 of the second floor 5a. The bolt 16 is cut by the force by which the first floor 5 pushes the reinforcing portion 6 of the second floor 5a, and the reinforcing portion 6 of the second floor 5a is movable in the longitudinal direction of the frame 13 toward the second gap 9a. To do.

  In the present embodiment, the length A ′ of the overlap between the second floor plate 8b and the first floor 5 side is as long as the length A4 capable of fixing the second floor plate 8b with the screw 18 is secured. good. Since the second floor plate 8b and the first floor 5 side are fixed, it is not necessary to make the length A 'longer than in the first embodiment.

As shown in FIG. 6, when the first floor 5 moves in the direction indicated by the arrow Z, the second floor plate 8 b moves together with the first floor 5 in the direction indicated by the arrow Z. For this reason, it is necessary to secure a length corresponding to the maximum assumed interlayer displacement (relative displacement) γmax on the length B ′ side where the second floor plate 8b overlaps the floor 14 on the lower floor building 2 side. . Accordingly, the length B ′ at which the second floor plate 8b overlaps the floor 14 on the lower floor building 2 side is at least larger than the maximum possible interlayer displacement γmax. Specifically, it is set as in Expression 4 so as to have a margin α.
B ′ = interlayer displacement γmax + margin α (Equation 4)
Thereby, it is possible to reliably prevent a gap from being generated between the second floor plate 8b and the floor 14 on the lower floor building 2 side.

  The configuration and operation other than those described above are the same as in the first embodiment.

  A third embodiment according to the present invention will be described with reference to FIG. FIG. 7 is a view showing a floor cross section of the passenger conveyor 1. This embodiment is a modification of the second embodiment, and the difference is that the reinforcing structure 20 of the second embodiment is added not only to the floor reinforcing portion 6 but also to the guide 30a as described in the first embodiment. It is a point that was configured.

  In this structure, the second floor plate 8b and the floor reinforcing portion 6 are not an integral structure, and the second floor plate 8b is configured to be relatively displaceable with respect to the floor reinforcing portion 6. The reinforcing structure 20 includes a floor reinforcing portion 6 and a guide 30a. The guides 30a are disposed on both sides of the floor reinforcing portion 6 in the longitudinal direction of the frame 13. One guide 30a is fixed to the stepped portion 2A by a bolt 16. In this embodiment, the guide 30a on the support portion 7 side is fixed to the stepped portion 2A with a bolt 16. The fixing with the bolt 16 is performed to prevent the displacement of the reinforcing structure 20. Reinforcement structure until the support part 7 of the passenger conveyor 1 or the first floor 5 collides with the reinforcement structure 20 of the second floor 5a by the fixing with the bolt 16 and the reinforcement structure 20 is pushed and the bolt 16 is cut. Allow 20 to maintain a predetermined position.

  In this embodiment, the lower surface of the guide 30a slides on the stepped portion 2A. Other configurations and operations are the same as those in the second embodiment, and common portions of the second embodiment with the first embodiment are shared in the present embodiment.
