Description

  Embodiments of the present invention relate to a passenger conveyor such as an escalator or a moving sidewalk and a method of attaching the same.

  The escalator is attached by spanning a truss between boarding places on the upper floor side and the lower floor side. This spanning is performed by placing a support that protrudes from the end of the truss on the anchor plate (base of the receiving beam) in the notch of the driver formed at the boarding places on the upper and lower floors. ing. Conventionally, the length protruding from the end of this truss has been designed to satisfy the seismic standards.

  However, recently, the seismic standards have been changed, and it is necessary to further increase the length of the protrusion from the end of the truss. However, in order to replace an existing escalator support, the entire escalator must be lifted by a heavy machine, so it is not easy to replace the support.

  Therefore, for example, as described in Patent Document 1, it has been proposed to fix an extension member (extension plate) that protrudes longer than the existing support tool to the existing support tool (support part). . According to this proposal, the length of the protrusion from the end portion of the truss can be increased without replacing the existing support tool. In addition, in the escalator of patent document 1, the jack bolt which penetrates an extending member hits an anchor plate, and supports the escalator.

Japanese Patent Laid-Open No. 2006-69100

  According to the above proposal, even if the support member is detached from the anchor plate, the extension member remains on the anchor plate. However, for example, when there is a step at the boundary between the lower surface of the support member and the lower surface of the extension member, the truss falls slightly when the support member is detached from the anchor plate, and an impact is generated. Also, if you try to adjust the height by inserting a shim between the support and the anchor plate in order to eliminate such a step, it will be necessary to jack up the truss, which will make the work heavy and the surrounding exterior Or hurt you.

  Therefore, the present invention can easily increase the length of the protrusion from the end of the truss, and even if the support provided on the end of the truss is detached from the anchor plate, it is difficult to generate an impact, and for that purpose. It is an object to provide a passenger conveyor that can realize the structure without jacking up the truss.

The passenger conveyor of the embodiment includes an anchor plate provided in a driving body cutout formed at a boarding / alighting place, a truss extending from one boarding / alighting place to the other boarding / alighting place, and projecting outward from an end of the truss A support member mounted on the anchor plate, a thin portion disposed above the support member and fixed to the support member, and protrudes longer outward than the support member and becomes thicker downward than the thin portion. An extension member having a thickened portion, wherein the thickened portion of the extension member is in contact with the anchor plate, a raising member is provided under the support, and the raising member is provided on the anchor plate. It is characterized by touching .

Further, the truss 10 includes a vertical intermediate frame member 15 that connects the upper frame member 11 and the lower frame member 12 at a plurality of positions between both ends of the upper floor side and the lower floor side, and the upper frame member 11 and the lower frame member. 12 and a horizontal intermediate frame member (not shown) that connects a pair of left and right upper frame members 11 and a pair of left and right lower frame members 12. With.

  The attachment structure on the lower floor side of the escalator 1 is shown in FIGS. The driving body cutout portion 4 at the boarding / alighting place is formed of concrete or the like. One of the surfaces forming the driving body cutout portion 4 is a horizontal mounting surface 6 that is lower than the floor surface 7. An anchor plate 30 is provided on the mounting surface 6. The upper surface of the anchor plate 30 is a horizontal plane lower than the floor surface 7. The anchor plate 30 extends to the end portion 5 on the upper floor side of the driver cutout portion 4.

  A support 31 is provided at the end of the truss 10 in the front-rear direction. The support tool 31 is, for example, a metal fitting. The support tool 31 is a member having an L-shaped cross section in the front-rear direction (the left-right direction in the figure), and a vertical plate 32 along the vertical frame member 13 of the truss 10 and the outer side of the escalator 1 from the upper end of the vertical plate 32. It consists of a horizontal plate 33 protruding in the direction of the front and rear direction away from the escalator 1. The vertical plate 32 is fixed to the upper frame material 11 and the vertical frame material 13 of the truss 10 by means of a fixing tool such as a bolt or welding. The horizontal plate 33 is on an extension of the upper frame member 11, and the upper surface of the upper frame member 11 and the horizontal plate 33 are at substantially the same height. The upper surface of the horizontal plate 33 is parallel to the upper surface of the anchor plate 30.

  And the horizontal board 33 of the support tool 31 is mounted on the anchor plate 30, and, thereby, the escalator 1 is supported. A raising member 34 such as a shim is sandwiched between the horizontal plate 33 and the anchor plate 30. The raising member 34 only needs to have a certain thickness. The raising member 34 may be a single member or may be formed by overlapping a plurality of members.

  Although not shown, the raising member 34 may not be provided between the horizontal plate 33 of the support 31 and the anchor plate 30, and the horizontal plate 33 may be in contact with the anchor plate 30. The expression that the support tool 31 (the horizontal plate 33) is placed on the anchor plate 30 includes the case where the raising member 34 is sandwiched between the horizontal plate 33 of the support tool 31 and the anchor plate 30 and the case where the support member 31 is not sandwiched. Is an expression.

  An extension member 40 is provided on the horizontal plate 33 of the support 31. The extending member 40 includes a thin portion 41 and a thick portion 42 that is thicker toward the lower side than the thin portion 41 on the outer side of the escalator 1 than the thin portion 41. The upper surface of the extension member 40 is a single plane parallel to the upper surface of the anchor plate 30. However, a spot facing portion is formed at a location of a bolt 45 described later on the upper surface of the extension member 40. On the other hand, on the lower surface side of the extending member 40, a step is formed at the boundary between the thin portion 41 and the thick portion 42. Note that the lower surface of the thin portion 41 and the lower surface of the thick portion 42 are each one plane parallel to the upper surface of the anchor plate 30.

  The thin portion 41 of the extension member 40 is disposed on the horizontal plate 33 of the support tool 31. The thin portion 41 and the horizontal plate 33 are fixed. Although the fixing method is not limited, in the present embodiment, the thin portion 41 of the extension member 40 and the horizontal plate 33 of the support 31 are fixed by bolts 45. Further, the thick part 42 of the extending member 40 protrudes to the outside of the escalator 1 from the support tool 31. The lower surface of the thick portion 42 is in contact with the anchor plate 30.

  An insertion member 46 such as a shim is sandwiched between the horizontal plate 33 of the support 31 and the thin portion 41 of the extension member 40. The insertion member 46 only needs to have a certain thickness. The insertion member 46 may be a single member or may be formed by overlapping a plurality of members. The thickness of the insertion member 46 is a thickness that fills a gap generated between the thin portion 41 of the extension member 40 and the horizontal plate 33 of the support 31 in a state where the lower surface of the thick portion 42 of the extension member 40 is in contact with the anchor plate 30. It has become. Therefore, the sum of the thickness of the insertion member 46, the thickness of the horizontal plate 33 of the support 31 and the thickness of the raising member 34 is equal to the vertical direction of the step at the boundary between the thin portion 41 and the thick portion 42 of the extension member 40. It corresponds to the length H (hereinafter referred to as “the length H of the step on the lower surface side of the extending member 40”). Thereby, the lower surface of the thick part 42 of the extending member 40 and the lower surface of the raising member 34 form the same plane and are in contact with the anchor plate 30. The insertion member 46 has a hole through which the bolt 45 passes.

  As shown in FIG. 3, in the present embodiment, one support tool 31 is provided extending from one end portion to the other end portion in the left-right direction (width direction, vertical direction in FIG. 3) of the truss 10. One extension member 40 is provided on each side of the support 31 in the left-right direction (width direction). The insertion member 46 and the raising member 34 are also provided one on each side in the width direction of the support tool 31.

  As shown in FIG. 2, the driver cutout 4 is closed by a floor closing plate 8. Further, a boarding / alighting plate 9 is provided adjacent to the floor closing plate 8 above the vicinity of the end of the truss 10. The floor surface 7, the floor closing plate 8, and the boarding / exiting plate 9 form a walking surface for the user of the escalator 1.

  Although not shown, the same mounting structure as that of the lower floor is also formed at the boarding place on the upper floor of the escalator 1. As a result, the escalator 1 is supported from the upper-layer side cutout portion 2 and the lower-floor side cutout portion 4.

2. As shown in FIG. 4, in the existing escalator 101, the horizontal plate 33 of the support 31 provided at the end of the truss 10 is placed on the raising member 34 on the anchor plate 30. It shall be. A method of completing the attachment of the escalator 1 by providing the extension member 40 and the like on the existing escalator 101 will be described.

  First, the extension member 40 is created. At this time, when the extension member 40 is fixed to the support 31, the extension direction of the extension member 40 is such that the protruding length from the end of the truss 10 to the tip of the extension member 40 satisfies the earthquake resistance standard ( Determine the length in the horizontal direction of the figure. The length H of the step on the lower surface side of the extension member 40 is set to be slightly longer than the length obtained by adding the thickness of the raising member 34 and the thickness of the horizontal plate 33 of the support tool 31.

  Next, the thickness of the insertion member 46 to be sandwiched between the horizontal plate 33 of the support 31 and the thin portion 41 of the extension member 40 in order to bring the anchor plate 30 and the thick portion 42 of the extension member 40 into contact is calculated. . Specifically, a value obtained by subtracting the thickness of the horizontal plate 33 of the support 31 and the thickness of the raising member 34 from the length H of the step on the lower surface side of the extension member 40 is defined as the thickness of the insertion member 46.

  Further, the floor closing plate 8 and the boarding / alighting plate 9 are removed from the existing escalator 101. Here, if the lengths of the front and rear cutouts 2 and 4 are less than the length required to attach the extension member 40, the floor 7 is shaved to move the cutouts 2 and 4 in the front and rear direction. Spread to. In addition, when the precursor cutout portions 2 and 4 are filled with mortar, the mortar is scraped off.

  Next, when there is no screw hole for the bolt 45 in the horizontal plate 33 of the support 31 in the existing escalator 101, a screw hole is formed in the horizontal plate 33 using a tap.

  Next, the insertion member 46 having the above thickness is placed on the horizontal plate 33 of the support 31 in the existing escalator 101.

  Next, the extension member 40 is put on the insertion member 46. Specifically, the thin portion 41 of the extension member 40 is placed on the insertion member 46, and the thick portion 42 of the extension member 40 is placed on the anchor plate 30. Then, the lower surface of the thick portion 42 and the lower surface of the raising member 34 are on the same plane, and the thick portion 42 of the extension member 40 and the anchor plate 30 are in contact with each other.

  Note that the thin portion 41 of the extension member 40 may be placed on the horizontal plate 33 of the support 31 first, and then the insertion member 46 may be sandwiched between the horizontal plate 33 and the thin portion 41.

  Next, the support tool 31 and the extension member 40 are fixed with the bolt 45.

  Finally, the floor closing plate 8 and the boarding / alighting plate 9 are attached. Thereby, the attachment of the escalator 1 is completed.

  When newly installing the escalator 1, first, the horizontal plate 33 of the support 31 provided at the end of the truss 10 is placed on the raising member 34 on the anchor plate 30. Next, the thin portion 41 of the extension member 40 is placed on the horizontal plate 33 of the support tool 31, and the support tool 31 and the extension member 40 are fixed.

  In the case of newly installing in this way, the raising member 34 is previously extended below the thick portion 42 of the extension member 40, and the extended portion is connected to the thick portion 42 of the extension member 40 and the anchor plate 30. You may pinch it. Alternatively, a shim having a thickness different from that of the raising member 34 may be sandwiched between the thick portion 42 of the extension member 40 and the anchor plate 30 before the support tool 31 and the extension member 40 are fixed. Alternatively, nothing may be sandwiched between the thick part 42 of the extension member 40 and the anchor plate 30.

3. Action and Effect The escalator 1 is greatly shaken due to a large earthquake and the like, so that the support 31 and the like are largely displaced from the anchor plate 30, and the support 31 and the raising member 34 are separated from the anchor plate 30 as shown in FIG. 5. Suppose that it has come off. However, in this embodiment, since the extension member 40 that protrudes longer than the support 31 is provided, the extension member 40 can remain on the anchor plate 30. The raising member 34 falls when it is detached from the anchor plate 30.

  Here, the extension member 40 is already in contact with the anchor plate 30 in a state where the support tool 31 and the raising member 34 are hooked on the anchor plate 30 (hereinafter, “normal state”). Therefore, there is no change in the state in which the extension member 40 is in contact with the anchor plate 30 before and after the support tool 31 and the lifting member 34 are detached from the anchor plate 30, and the support tool 31 and the lifting member 34 are not connected to the anchor plate 30. Since the truss 10 does not fall when it deviates from 30, it is difficult for an impact to occur.

  As described above, in the present embodiment, the extension member 40 is simply put on the support 31 of the existing escalator 101 and the support 31 and the extension member 40 are fixed. The length can be easily increased. Further, since the extension member 40 is in contact with the anchor plate 30 in a normal state, when the support tool 31 and the raising member 34 are detached from the anchor plate 30, the impact is hardly generated as described above. Further, by inserting the insertion member 46 between the horizontal plate 33 of the support 31 and the thin portion 41 of the extension member 40 and adjusting the height, the thick portion 42 of the extension member 40 and the anchor plate 30 in the normal state are adjusted. Can be easily realized. Further, it is not necessary to jack up the truss 10 in order to realize a structure that exhibits these effects.

4). Modification Example A modification example of the above embodiment will be described. Any one of a plurality of modifications described below may be applied to the above embodiment, or any two or more of the modifications described below may be selected and applied. Also good. However, various modifications other than the following modification examples are possible, and the scope of the invention is not limited to the above-described embodiment and the scope of the following modification examples. 6 to 9 showing the modification examples, the same parts as those in FIGS. 1 to 5 are denoted by the same reference numerals.

(Modification 1)
As shown in FIGS. 6 and 7, in the first modification, the extension member 240 is extended to a location above the truss 10. A reinforcing bolt 241 as a protruding member that protrudes downward toward the truss 10 is provided in a portion above the truss 10 of the extension member 240. The tip of the reinforcing bolt 241 may be in contact with the upper frame member 11 of the truss 10, but even if a backing plate 242 is sandwiched between the reinforcing bolt 241 and the upper frame member 11 of the truss 10 as shown in the figure. good.

  When the escalator 1 is greatly shaken and the support 31 and the raising member 34 are detached from the anchor plate 30, an upward force acts on the truss 10 as shown by an arrow A in FIG. As shown, a force in the direction of separating the support member 31 and the extension member 40 from the bolt 45 acts, and it is expected that an excessive load is applied to the bolt 45. However, if the above-described reinforcing bolt 241 is provided as shown in FIG. 6, a force pressing downward from the reinforcing bolt 241 against the truss 10 is applied. As a result, the force in the direction of separating the support tool 31 and the extension member 240 is relaxed, and the load on the bolt 45 is reduced.

  The protruding member may be a member that protrudes downward from the portion above the truss 10 of the extension member 240 toward the truss 10, and may not be the illustrated reinforcing bolt 241.

(Modification 2)
As shown in FIG. 8, a pin 245 that penetrates the thick portion 42 of the extension member 40 and the anchor plate 30 may be provided. The pin 245 has such a strength that it cannot be broken with a small force but can be broken with a large force.

  In this modified example, even if a small earthquake occurs, the extension member 40 and the anchor plate 30 are fixed by the pin 245, so that the truss 10 does not shift with respect to the driver cutout portions 2 and 4 at the place of getting on and off. However, when a large earthquake occurs, a large force is applied to the pin 245, the pin 245 is broken, and the truss 10 is displaced with respect to the driver's notch portions 2 and 4 at the place of getting on and off. In this way, the pin 245 can prevent the truss 10 from shifting when a small earthquake occurs, which is a case where the truss 10 does not need to be displaced, and a large earthquake occurs when the truss 10 is preferably displaced. In such a case, the truss 10 can be displaced.

(Modification 3)
As shown in FIG. 9, a mortar cover 250 that covers the extension member 40 may be provided. The mortar cover 250 forms a wall at least above the thick portion 42 of the extension member 40 and in the direction of the side of the extension member 40 where at least mortar (not shown) is filled. The mortar cover 250 in FIG. 9 includes at least an upper wall 251 and a side wall 252 on the outer side in the front-rear direction of the escalator 1. The height of the mortar cover 250 is a height that can be accommodated in the fuselage notch 4 formed at the place of getting on and off. As shown in FIG. 9, an insertion member 253 such as a shim may be sandwiched between the upper surface of the extension member 40 and the mortar cover 250.

  A floor closing plate 8 is provided above the mortar cover 250. In FIG. 9, the mortar cover 250 and the floor closing plate 8 are in contact with each other. However, a space may be provided between the mortar cover 250 and the floor closing plate 8, or mortar may be filled.

  When this mortar cover 250 is used, first, the extension member 40 is attached in the same manner as in the above embodiment. Next, the mortar cover 250 is put on the extension member 40. Next, mortar is filled in a place outside the side wall 252 in the fuselage cutout portion 4. If necessary, the mortar cover 250 is also filled with mortar. Finally, the floor closing plate 8 and the boarding / exiting plate 9 are covered.

  Thus, by covering the extension member 40 with the mortar cover 250, it is possible to prevent the extension member 40 and the support member 31 therebelow from being fixed by the mortar and becoming unable to move.

(Modification 4)
There is also a sidewalk that moves as a passenger conveyor. The same mounting structure as that of the above embodiment can be adopted also on a moving sidewalk or the like.

  In addition to the above modification examples, various modifications, substitutions, omissions, and the like can be made without departing from the scope of the invention. The above embodiment and modification examples are illustrative, and the scope of the invention is not limited thereto. The above embodiments and modifications are included in the invention described in the claims and the equivalents thereof.
