Description
Technical Field
The present invention relates to a floor structure of a passenger conveyor.
Background
In general, a floor is provided in a floor portion of a passenger conveyor where a passenger gets on and off, and a machine room is provided below the floor. The machine room is surrounded by, for example, a truss structure, and a drive machine and a control panel are provided inside the machine room. When performing maintenance, check, repair, or the like of the passenger conveyor, the operator removes the floor and enters the machine room to perform check work, or the like.

Disclosure of Invention
Problems to be solved by the invention
The floor of the passenger conveyor is often provided above the machine room of the passenger conveyor by its own weight, and is not mechanically fastened to the outside. However, there are cases where the passenger conveyor is grounded outdoors or in an outdoor-facing environment. In such a case, the floor of the passenger conveyor may be exposed to strong wind when a typhoon or the like is blown. When strong wind blows from the floor, the air pressure drops near the front of the floor to generate negative pressure, and the machine room becomes relatively high pressure. As a result, buoyancy is generated in the floor placed on the machine room. In the case where the floor is not mechanically fastened, a phenomenon in which the floor floats occurs when the buoyancy exceeds the weight of the floor. When the floor panel is raised to a height not less than the thickness, the rear surface of the floor panel is also blown by wind. As a result, there is a fear that the floor panel is separated from the construction ground around the floor panel.
In contrast, a truss structure or the like for fastening the floor to the lower portion may be considered. However, mechanical fastening of the floor panel requires additional fastening members, which complicates the structure and increases the cost. Further, mechanical fastening has a limitation in strength, but the wind speed has no substantial upper limit, and an unexpected buoyancy may act on the floor, and there still remains a problem of floating and separation of the floor.
The invention aims to provide a floor structure which is improved to prevent the separation of the floor by reducing the pressure difference between the machine room which becomes the cause of the buoyancy and the outside air without adding a component for fastening the floor.
Means for solving the problems
The floor structure of the passenger conveyor of the invention is the following floor structure: the floor is arranged at a landing position of a passenger conveyor and used for opening and closing an upper opening part of a machine room below the landing position, wherein the floor comprises: a plurality of holes which penetrate from the front surface of the floor as a boarding and alighting position to the back surface opposite to the machine room; and a groove-shaped flow guide groove which is arranged on the vertical lower side of the plurality of holes and faces the plurality of holes to be opened.
Effects of the invention
According to the floor structure of the passenger conveyor of the present invention, a plurality of holes are formed in the floor, and the plurality of holes penetrate from the front surface of the floor to the back surface of the machine room side. Thus, even when the front surface of the floor panel is exposed to strong wind and negative pressure is generated, the air is ventilated through the plurality of holes, so that the air pressure difference between the front surface side and the back surface side of the floor panel can be reduced. This can effectively suppress the floating and separation of the floor.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and the description thereof is simplified or omitted.
Fig. 1 and 2 are diagrams schematically showing a structure in the vicinity of a boarding/alighting place of a passenger conveyor according to the present embodiment, fig. 1 shows a cross section parallel to a moving direction and a vertical direction, and fig. 2 shows an upper surface of the passenger conveyor. In the example shown in fig. 1 and 2, an escalator 1 is illustrated as a passenger conveyor. However, the structure of the floor of the passenger conveyor described later can be applied to other passenger conveyors such as moving walkways, for example. The structure of the escalator 1 near the boarding/landing position will be described with reference to fig. 1 and 2.
The escalator 1 is disposed across different floors of a building. The escalator 1 is a transportation device that transports a user by riding on steps that move between a boarding/alighting portion 2 provided on the upper floor side and a boarding/alighting portion provided on the lower floor side. The landing place 2 of the upper floor and the landing entrance of the lower floor are connected by a moving passage 3 through which a plurality of steps move. Balustrades 4 are disposed on both sides of the moving path 3 in the width direction, and the balustrades 4 are provided with a pair of skirt portions and a moving handrail.
On the side of the vertical landing part 2 of the escalator 1 that is in contact with the end of the moving path 3, there are provided comb teeth 5 and a rubber plate 6 that extend in the width direction of the escalator 1. A floor 10 is attached to the vertical access 2 so as to contact the rubber sheet 6. The outer peripheral side of the floor 10 is surrounded by the building floor 7 of the boarding/alighting floor. A recess corresponding to the thickness of the floor panel 10 is formed in the installation position of the floor panel 10 of the building floor 7, and a frame portion in which a seam is arranged is formed on the front surface. By providing the floor panel 10 to the frame, the building floor 7 and the floor panel 10 are flush with each other. In addition, in order to detach the floor panel 10, a slight gap is formed between the joint of the frame portion and the floor panel 10. In the present embodiment, the floor panel 10 is fitted into the frame portion due to its own weight.
In the example of fig. 1 and 2, the floor 10 is formed of two pieces, and is arranged on the side close to the moving path 3 and the back side. On the front surface of the floor 10 on the side close to the moving passage 3 among the floor 10, floor characters indicating the number of floors at the boarding/alighting place are displayed.
A machine room 8 is provided at the lower part of the floor 10. The machine room 8 is a space surrounded by the truss structure 9, and a drive machine for driving the escalator 1, a control panel for controlling the operation of the escalator 1, wiring equipment, and the like are collectively arranged therein. The floor 10 also functions as a door of the machine room 8. That is, when the escalator 1 is subjected to work such as maintenance and repair, the floor 10 is removed or opened, so that the worker can enter the machine room 8.
Fig. 3 and 4 are diagrams schematically illustrating the structure of the floor panel 10 of the present embodiment, fig. 3 illustrating the front side of the floor panel 10, and fig. 4 illustratingbase:Sub>A cross sectionbase:Sub>A-base:Sub>A of the floor panel 10 of fig. 3.
As shown in fig. 3 and 4, a plurality of holes 12 are formed in the outer peripheral portion of the floor panel 10. Each hole 12 penetrates the floor panel 10 in the vertical direction from the front surface 10a of the floor panel 10 toward the rear surface 10b facing the machine room 8. The holes 12 are regularly arranged in a plurality of rows in the outer periphery of the floor panel 10. That is, when the floor panel 10 is viewed from the front surface 10a or the rear surface 10b, a strip-shaped lattice pattern is formed in the outer peripheral portion of the floor panel 10.
The size of each hole 12 (i.e., the surface area of the front face 10 a) is sufficiently small to be unlikely to cause a pedestrian to trip or get caught. In addition, the number of holes 12 is determined so that sufficient air permeability can be ensured between the front surface 10a side and the rear surface 10b side of the floor panel 10 in consideration of the size of the holes 12.
On the rear surface 10b side of the floor 10, a gutter 13 as a gutter-shaped gutter is disposed so as to cover the vertically lower side of all the holes 12. That is, the gutter 13 is opened so as to face the rear surface 10b of the floor 10, and is arranged so as to surround the outer peripheral portion of the rear surface 10b by a width wider than the width of the portion where the hole 12 is formed. The gutter 13 is provided as a gutter having a volume sufficient to prevent liquid such as rainwater falling from the hole 12 from overflowing.
The gutter 13 is provided with a drain port 15. The drain port 15 is connected to a drain pipe for draining water to the outside. The drain port 15 and the drain pipe are formed in a diameter that can secure drainage performance enough to prevent liquid from overflowing the storm drain 13. The drain port 15 is formed on the inner peripheral side of the hole 12 so as not to overlap the hole 12 formed portion in a view projected in the vertical direction on the floor 10 and the gutter 13. Fig. 3 shows a position B obtained by projecting the formation position of the drain opening 15 in the vertical direction.
The height of the sidewall 16 on the inner peripheral side of the gutter 13 in the vertical direction is lower than the height of the sidewall 17 on the outer peripheral side. In a cross section perpendicular to the flow direction of rainwater or the like in the gutter 13, the top of the side wall 16 on the inner peripheral side of the gutter 13 is separated from the rear surface 10b of the floor 10 by a space C.
According to the construction of the floor panel 10 of the present embodiment, a plurality of holes 12 sufficient to ensure ventilation are formed near the outer periphery of the floor panel 10, and a certain space C is ensured between the side wall 16 of the storm drain 13 and the back surface 10b of the floor panel 10. Thus, even when strong wind blows over the front surface 10a of the floor 10 and negative pressure is generated on the front surface 10a of the floor 10, the pressure difference between the front surface 10a side and the machine room 8 side of the floor 10 can be reduced by ventilating the front surface 10a side and the machine room 8 side of the floor 10 through the holes 12. Therefore, even when the floor panel 10 is installed only in a state of being fitted into the frame portion of the surrounding building floor 7, the floating, separation, and the like of the floor panel 10 due to strong wind can be effectively suppressed.
Further, a gutter 13 is disposed below the portion of the floor 10 where the hole 12 is formed in the vertical direction. This prevents liquid such as rainwater and foreign matter such as stones, sand, and soil from falling down from the holes 12 into the machine room 8.
In the present embodiment, the case where the holes 12 are arranged in a plurality of rows in a lattice shape in the outer peripheral portion of the floor panel 10 has been described. This is because, in order to ensure sufficient ventilation, it is structurally simple to provide the gutter 13 near the outer periphery of the floor panel 10. However, the arrangement of the holes 12 is not limited thereto. If the size of the holes 12 is set to a small size that can avoid stumbling of a pedestrian and sufficient ventilation is ensured, the holes 12 may be arranged only once in the outer peripheral portion, for example, or may be arranged so that the holes 12 draw a certain pattern shape on the front surface 10a of the floor panel 10. However, although the gutter 13 is required vertically below all the holes 12, if the arrangement range of the gutter 13 is too large, the gutter 13 may adversely reduce the ventilation. Therefore, the surface area of the portion where the hole 12 is formed is preferably 40% to 50% or less of the surface area of the floor panel 10.
In the present embodiment, the gutter 13 is a continuous gutter that extends around the outer periphery of the floor panel 10 so as to cover the vertical lower side of the portion where the hole 12 is formed. However, the gutter 13 need not be a single member as long as it is disposed vertically below all the holes 12, and may be a plurality of divided gutters that are attached to the floor 10 on each side of the outer periphery thereof.
The drain port 15 for discharging the liquid in the gutter 13 to the outside is formed at a position vertically below the avoidance hole 12. This prevents foreign matter falling through the hole 12 from directly falling into the drain opening 15 to block the drain opening 15. However, the position of the drain port 15 is not limited to the inner peripheral side of the portion where the hole 12 is formed. The drain port 15 may be formed at another position as long as it is formed at a position avoiding the vertical lower side of the hole 12. In the present embodiment, although one drain opening 15 is illustrated and described, the number of drain openings 15 is not limited, and a plurality of drain openings 15 may be provided.
The floor 10 of the present embodiment may be fastened to the truss structure 9 surrounding the machine room 8 by fastening members. When the floor 10 is mechanically fastened to the machine room 8, the floor 10 can be more reliably prevented from floating and separating due to the fastening force and the effect of reducing the air pressure difference by the holes 12.
In the present embodiment, a case where two floor boards 10 are disposed in parallel on the moving walkway 3 side and the back side is described. However, the number of the floor panels 10 to be used is not limited to two, and may be one or 3 or more. The size of one floor 10 and the number of blocks used for the floor 10 are appropriately determined depending on the width of the boarding/alighting place 2, the structure of the building floor 7 around the boarding/alighting place, and the like.
The escalator of embodiment 2 is the same as the escalator 1 of embodiment 1, except that the floor 20 is used instead of the floor 10. Fig. 5 and 6 are views schematically showing the configuration of the floor panel 20 of the present embodiment, fig. 5 showing the front surface of the floor panel 20, and fig. 6 showing a D-D section of fig. 5.
As shown in fig. 5 and 6, the floor panel 20 has a grill member 21. The grill member 21 is made of steel assembled into a lattice shape, and a plurality of holes penetrating the front and rear surfaces of the grill member 21 are arranged in a lattice shape as a whole.
A front panel 22 having a smaller surface area than the surface area of the grill member 21 is attached to the front surface of the grill member 21. The floor panel 20 leaves a portion uncovered by the front panel 22 and exposing the grill member 21. The hole of the grill member 21 located at the exposed portion functions as a hole of the floor panel 20 instead of the hole 12 of embodiment 1.
A gutter 23 is provided on the back surface side of the grill member 21. The gutter 23 is a gutter-shaped flow guide gutter, and is disposed vertically below a portion of the grill member 21 that is exposed without being covered by the front plate 22 (hereinafter also simply referred to as "exposed portion") so as to surround the outer periphery of the rear surface of the grill member 21. That is, the gutter 23 is disposed so as to be open to the rear side of the exposed portion of the grill member 21. The gutter 23 is formed to be slightly wider than the width of the exposed portion of the grill member 21 and to extend vertically below the outer peripheral portion of the front plate 22. A drain opening 25 is formed in a portion of the storm drain 23 located vertically below the front panel 22. Fig. 5 shows a position E obtained by projecting the formation position of the drain port 25 in the vertical direction.
Similarly to the storm drain 13 of embodiment 1, the height of the inner peripheral side wall 26 of the storm drain 23 in the vertical direction is lower than the height of the outer peripheral side wall 27. Thereby, a space F is formed between the top of the side wall 26 on the inner peripheral side of the gutter 23 and the back surface of the floor 20.
As described above, by forming the floor panel 20 using the grill member 21, as in the case of embodiment 1, it is possible to suppress the occurrence of a pressure difference between the front surface side and the back surface side of the floor panel 20 due to strong wind, and to suppress floating, separation, and the like of the floor panel 20.
The gutter 23 is disposed vertically below the exposed portion of the grill member 21 of the floor 20. This prevents liquid such as rainwater and foreign matter such as stones, sand, and soil from falling through the holes of the grid member 21 into the machine room 8.
In the present embodiment, a case has been described in which the front panel 22 is provided on the inner peripheral side of the grill member 21, and the exposed portion is disposed on the outer peripheral portion of the floor panel 20. However, the shape, the installation location, and the installation area of the front panel 22 are not limited to the configurations shown in fig. 5 and 6. The front plate 22 may be disposed so that the holes of the grill member 21 are exposed only once on the outer peripheral portion, for example, as long as the exposed portion of the grill member 21 has a width that ensures sufficient ventilation. The exposed portions are not limited to being equally arranged on 4 sides of the floor panel 20, and may be formed only on two sides of the end portion side in the width direction, for example. However, as in the case of embodiment 1, in order to suppress a reduction in air permeability due to the rain gutter 23 on the back surface, the area of the exposed portion is preferably 40% to 50% or less of the surface area of the floor panel 20.
Further, as in the case of embodiment 1, the gutter 23 is not limited to surrounding the outer periphery of the floor panel 20. The gutter 23 may be a gutter divided into a plurality of parts and installed on the floor 20, for example, as long as it is disposed vertically below the entire exposed part.
The drain port 25 of the gutter 23 is not limited to the position shown in fig. 5 and 6 as long as it is not located vertically below the exposed portion. The number of the drain openings 25 is not limited, and a plurality of drain openings 25 may be provided.
In addition, the floor 20 of the present embodiment may be fastened to the truss structure 9 surrounding the machine room 8 by fastening members, as in the case of embodiment 1. The number of the floor boards 20 is not limited to two, and may be one or 3 or more.
The floor panel 10 according to embodiment 3 is similar to the floor panel 10 according to embodiment 1, except that the guide 31 is formed on the rear surface 10b side of the floor panel 10. Fig. 7 is a sectional view showing the structure of the floor panel of embodiment 3, and shows a section corresponding to fig. 4.
As shown in fig. 7, the guide 31 is a rod-shaped member and is disposed on the innermost periphery of the portion of the rear surface 10b of the floor panel 10 where the hole 12 is formed. That is, the guide 31 is disposed at a portion on the inner circumferential side of the hole 12 in the row on the innermost circumferential side among the holes 12 formed in the floor panel 10 so as to protrude toward the gutter 13.
In the case where the guide 31 is not formed, there is a concern that: the liquid, foreign matter, and the like falling from the hole 12 move by wind before reaching the rain gutter 13, fall to a position deviated from the rain gutter 13, or move along the back surface 10b of the floor 10 and fall into the machine room 8. In contrast, according to embodiment 3, the liquid, foreign matter, or other falling objects falling from the hole 12 are guided to the gutter 13 by the guide 31. Therefore, the falling object can be more reliably prevented from deviating from the storm drain 13 and falling into the machine room 8.
The guide 31 may be provided only in each hole 12 disposed on the innermost peripheral side, or may be provided in all the holes 12, for example. Further, only any hole 12 of the plurality of holes 12 may be provided.
The guide 31 is not limited to a rod-shaped member, and may be a protrusion-shaped member protruding toward the gutter 13, for example.
Further, although the description has been given of the structure in which the guide 31 is provided on the floor panel 10 of embodiment 1, the guide 31 may be formed on the floor panel 20 of embodiment 2. That is, the guide 31 may be disposed on the rear surface side of the hole of the floor panel 20 of embodiment 2, which is located in the exposed portion of the grill member 21.
