Description

  The present invention relates to a passenger conveyor such as an escalator, and more particularly, to a passenger conveyor in which a fixed state between each of support members provided at both ends of a truss and a support beam in a building is a so-called non-fixed state.

  The escalator is configured such that a part of each of the support members provided at both ends of the truss is provided on a pedestal fixed to a support beam on the upper floor side of the building and a pedestal fixed on the support beam on the lower floor side, respectively. It is hung and installed in the building concerned. Here, a portion of the support member that is hung on the cradle is referred to as a support portion.

  If the building shakes due to an earthquake, etc., the horizontal distance between the upper support beam and the lower support beam expands / contracts, causing interlayer displacement, and the distance between the pedestals changes. I do. For this reason, one support member (support portion) is fixed to the corresponding pedestal, and the other support member (support portion), so that the truss or the like is not deformed by safety from the external force from the building body. Can be installed in a fixed state at one end in a state of sliding with respect to the corresponding cradle, or both support members can be installed in an unfixed state at both ends in a state of sliding with respect to the corresponding cradle. It is required (2013 Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1046 No. 1 Paragraph 1 No. 2).

  In Patent Document 1, one of the bearings is fixed to a semi-fixed pin with one end fixed, and when an excessive load acts on the semi-fixed pin due to a large-scale earthquake or the like, the fixed pin is broken and both the bearings are broken. A passenger conveyor that absorbs interlayer displacement in the longitudinal direction of a truss by being in a state where both ends are not fixed is disclosed.

  By the way, when the distance between the upper and lower floor support beams is longer than the design value due to the construction error of the building frame, or when the total length of the truss is shorter than the design value due to manufacturing error, the The gap becomes larger than the design value. In this way, in preparation for the case where the gap becomes larger than the design value, the allowance of the above-described support portion, that is, the support portion is slidable when the support portion is displaced in a direction away from the support of the support beam. If the horizontal distance is not long, the truss may fall off due to interlayer displacement. For this reason, in the conventional truss, it is necessary to provide a longer allowance for the support portion than necessary in anticipation of a case where the gap between the truss and the support beam becomes larger than a design value.

  An object of the present invention is to provide a passenger conveyor that can prevent the truss from falling off without unnecessarily extending the length of the support portion even if the measured value of the gap between the truss and the support beam is larger than a design value. .

  A passenger conveyor according to one aspect of the present invention includes a first support portion and a second support portion extending horizontally from the truss in the longitudinal direction thereof at both ends of the truss, and both the support portions are provided with a first support beam of a building. A first support beam and a second support beam having different heights are slidably hung along the longitudinal direction, respectively, and the first truss abuts on the first support beam when the truss is displaced toward the first support beam. What is claimed is: 1. A passenger conveyor comprising an abutment portion and a second abutment portion which abuts on the second support beam when the truss is displaced toward the second support beam, wherein the truss is directed toward the first support beam. By contacting the first support beam instead of the first contact portion when displaced, an actual measurement value of the first gap between the first contact portion and the first support beam and the second contact portion are provided. Based on the first correction distance obtained by subtracting the design value of each of the gaps from the actually measured value of the second gap between the second support beam and the second gap. Those comprising a first gap adjusting member to reduce the displacement distance of the truss Te.

  In the passenger conveyor according to one aspect of the present invention, the gap adjustment member may be configured to be able to adjust a horizontal length extending from the first contact expected portion toward the first support beam.

  Further, in the passenger conveyor according to one aspect of the present invention, as the gap adjusting member, a member having a thickness closest to the correction distance is selected from a plurality of gap adjusting members having different horizontal thicknesses when attached to the truss. May be.

  A passenger conveyor according to another aspect of the present invention includes a first bearing and a second bearing extending horizontally in the longitudinal direction from both ends of a truss, and both bearings are provided with a first support beam of a building and a first bearing. A first abutment which is slidably hung on the support beam and a second support beam having a different height along the longitudinal direction, and which comes into contact with the first support beam when the truss is displaced toward the first support beam; A passenger conveyor including a scheduled portion and a second scheduled contact portion that abuts on the second support beam when the truss is displaced toward the second support beam, wherein the truss is displaced toward the first support beam. At this time, by contacting the first support beam instead of the first contact portion, the design value of the first gap can be calculated from the actually measured value of the first gap between the first contact portion and the first support beam. A first gap adjusting member for reducing the displacement distance of the truss by a distance based on the subtracted first correction distance; When the truss is displaced toward the holding beam, by contacting the second support beam instead of the second contact portion, the measured value of the second gap between the second contact portion and the second support beam And a second gap adjusting member for reducing the displacement distance of the truss by a distance based on the second correction distance obtained by subtracting the design value of the second gap from the second gap.

  According to the passenger conveyor according to one aspect of the present invention, when the truss is displaced toward the first support beam, the first gap adjustment member contacts the first support beam, so that the first gap and the second gap are adjusted. The displacement distance of the truss can be reduced by a distance obtained by subtracting the design value of both gaps from the actually measured value of the gap. For this reason, it is possible to prevent the truss from falling off without providing an unnecessarily long length of the margin of the second support portion on the opposite side.

  According to the passenger conveyor according to another aspect of the present invention, when the truss is displaced toward the first support beam, the first gap adjustment member comes into contact with the first support beam, so that the measured value of the first gap is measured. The displacement distance of the truss can be reduced by a distance obtained by subtracting the design value from the truss. Further, when the truss is displaced toward the second support beam, the second gap adjusting member comes into contact with the second support beam, so that the truss displacement is a distance obtained by subtracting the design value from the actually measured value of the second gap. The distance can be shortened. For this reason, it is possible to prevent the truss from dropping off without providing an unnecessarily long dimension of the allowance of the two support portions.

  Hereinafter, a first embodiment of a passenger conveyor of the present invention will be described with reference to the drawings. FIG. 1 is a diagram schematically illustrating an escalator according to a first embodiment of the present invention.

  As shown in FIG. 1, the escalator 10 includes a truss 16 bridged between a concrete beam (first support beam) 12 on the upper floor and a concrete beam (second support beam) 14 on the lower floor. And an endless transport body 20 for transporting passengers. The truss 16 has an upper floor end 17 provided with an upper machine room M1, a lower floor end 18 provided with a lower machine room M2, and an inclined portion connecting both ends 17, 18. 19, and are erected on both beams 12, 14 in a state where both ends are not fixed.

  The endless carrier 20 includes a driving sprocket 22 and a driven sprocket 24, a number of steps 26a, 26b, 26c connected endlessly by a driving chain 25 bridged between the sprockets 22, 24, and a driving sprocket 22. (Not shown) for driving the motor. A balustrade 27 is provided along both sides of the endless transport body 20. On the balustrade 27, a handrail 28 that runs in conjunction with the circulation of the steps 26a, 26b, 26c is installed.

  FIG. 2A is a partially enlarged view illustrating the configuration of the lower floor end 18 of the truss 16, and FIG. 2B is a partially enlarged view illustrating the configuration of the upper floor end 17 of the truss 16. is there. 2A and 2B, illustration of a mortar material MR described later is omitted.

  As shown in FIGS. 2A and 2B, support members 30, 33 extending toward the concrete beams 12, 14 are provided at both ends 17, 18 of the truss 16. In the following description, since the configurations of the support members 30 and 33 are substantially the same, the description will be mainly given of the upper-floor support member 30 shown in FIG. A description will be appropriately omitted.

  As shown in FIG. 2B, the support member 30 includes an angle iron 31 having a vertically extending side portion (first contact planned portion) 31 a fixed to the upper end 17 of the truss 16 by welding or the like. And an extension plate (supporting portion) 32 having one end fixed to a substantially horizontal side 31b of the angle iron 31 by welding or the like. A first gap G <b> 1 is provided between the side 31 a of the angle iron 31 and the concrete beam 12. The side portion 31a has a role of abutting on the concrete beam 12 when the truss 16 is displaced toward the concrete beam 12 when a gap adjusting member described later is not provided.

  The extension plate 32 is slidable in the X direction on spacers SP1 and SP2 (see FIG. 3) welded and fixed to the pedestal 37 of the step-down portion 12a formed by cutting out a part of the upper surface of the concrete beam 12. It is placed in a state. The spacers SP1 and SP2 have a function of adjusting the height position of the truss 16 in the erected state, and are configured by laminating thin metal plates (shims). In the following description, a portion where the extension plate 32 constituting the support member 30 overlaps the pedestal 37 in a top view is referred to as a margin α1. The dimension in the X direction of the allowance α1 is larger than a length obtained by adding an interlayer displacement γ · H (γ: interlayer displacement angle for escalator design, H: floor height (see FIG. 1)) to a second gap G2 described later. It is provided slightly longer so that the truss 16 does not fall off even if the truss 16 is displaced toward the concrete beam 14.

  In the present embodiment, the angle iron 31 is erected on the concrete beam 12 via the extension plate 32. However, the angle iron 31 may be erected directly on the cradle 37 without using the extension plate 32. In this case, the substantially horizontal side 31b of the angle iron 31 corresponds to the bearing.

  Further, as shown in FIG. 1, when the step-down portion 12 a is buried with the mortar material MR, the mortar reject cover 37 a may be provided so as to cover the upper surface of the receiving stand 37. The mortar cover 37a is open on the truss 16 side, and has a role of securing a sliding space in which the extension plate 32 slides when the truss 16 is displaced in the longitudinal direction X. A gap β1 is provided between the wall surface W1 of the mortar cover 37a and the extension plate 32 to secure a sliding distance of the extension plate 32. The length of the gap β1 in the longitudinal direction X is the sliding distance of the extension plate 32 when the truss 16 is displaced toward the concrete beam 12 (the length obtained by subtracting the thickness of a gap adjusting member described later from the first gap G1). ) Is provided so as to be slightly larger. By providing the gap β1 longer than the sliding distance of the extension plate 32, the extension plate 32 is prevented from colliding with the mortar cover 37a.

  On the other hand, as shown in FIG. 2A, the support member 33 is slidably placed on the pedestal 39 similarly to the support member 30. A second gap G <b> 2 is provided between the side 34 a of the angle iron 34 constituting the support member 33 and the concrete beam 14. In the following description, a portion where the extension plate (second support portion) 35 constituting the support member 33 overlaps the pedestal 39 in a top view is referred to as a margin α2. The dimension in the X direction of the allowance α2 is determined by the length obtained by adding the interlayer displacement γ · H (γ: interlayer displacement angle for escalator design, H: floor height <see FIG. 1) to the first gap G1, and the gap described later. It is provided slightly longer than the length obtained by subtracting the thickness of the adjusting member, so that the truss 16 does not fall off even if the truss 16 is displaced toward the concrete beam 12.

  The pedestal 39 has the same configuration as the above-described pedestal 37, and is provided with a mortar exclusion cover 39a. A gap β2 is provided between the wall surface W2 of the mortar cover 39a and the extension plate 35 to secure a sliding distance of the extension plate 35. The length of the gap β2 in the longitudinal direction X is provided so as to be slightly larger than the sliding distance of the extension plate 35 toward the concrete beam 14 (ie, the second gap G2).

  Next, the configuration of the gap adjusting members 44 and 46 will be described with reference to FIGS. FIG. 3 is a cross-sectional view taken along line AA shown in FIG. As shown in FIGS. 2B and 3, the truss 16 includes gap adjusting members 44 and 46 each having a substantially box-like appearance at both ends in the width direction of the side 31 a of the angle iron 31. Each of the gap adjusting members 44 and 46 has a function of adjusting the displacement distance of the truss 16 by abutting the concrete beam 12 instead of the side 31a of the angle iron 31 when the truss 16 is displaced toward the concrete beam 12. Have. Since the gap adjusting members 44 and 46 have the same configuration, only the gap adjusting member 44 will be described. The number of the gap adjusting members may be one or more. However, in the present embodiment, by using the two gap adjusting members 44, 46, the gap adjusting members 44, 46 come into contact with the concrete beam 12. The contact force acting on the truss 16 is dispersed so that the truss is hardly damaged.

  Subsequently, a method of setting the thickness t of the gap adjusting member 44 will be described with reference to FIGS. 2A and 2B. As shown in FIGS. 2A and 2B, the gaps G1, G2 between the concrete beams 12, 14 and the truss 16 are measured with the truss 16 laid on the concrete beams 12, 14 on the upper and lower floors. Obtain the actual measured value. Then, the thickness t of the gap adjusting member 44 is formed so as to be a correction distance obtained by subtracting the design value of the gaps G1 and G2 from the sum of the actually measured values of the gaps G1 and G2. Attach.

  Thereby, the displacement distance when the truss 16 is displaced toward the concrete beam 12 can be reduced by a distance (that is, the thickness t) corresponding to the difference between the measured value and the design value of the gaps G1 and G2. Further, since the displacement distance of the truss 16 when displacing toward the concrete beam 12 is shortened by the distance corresponding to the thickness t, the dimension in the X direction of the extension plate 35 on the lower floor side is also reduced by the distance corresponding to the thickness t. Can be shortened. Since the dimension of the extension plate 35 can be reduced by the dimension corresponding to the thickness t in this way, the dimension in the X direction of the step-down portion 14a of the concrete beam 14 on the lower floor side can also be reduced by the distance corresponding to the thickness t (FIG. 2). (A)).

  According to the escalator 10 in the present embodiment, when the truss 16 is displaced toward the concrete beam 12, the gap adjusting members 44 and 46 abut on the concrete beam 12, so that the design values are obtained from the actually measured values of the gaps G1 and G2. , The displacement distance of the truss 16 can be shortened by the thickness t corresponding to the correction distance obtained by subtracting the above. For this reason, it is possible to prevent the truss 16 from falling off without providing an unnecessarily long dimension of the margin α2 of the extension plate 35 on the lower floor, and the dimension of the plate 35 corresponds to the thickness t of each of the gap adjusting members 44 and 46. You can reduce the distance you do.

  Accordingly, the dimension of the stepped portion 14a in the X direction of the concrete beam 14 in the X direction can be shortened by a distance corresponding to the above-described thickness t, so that it is not necessary to cut the concrete beam 14 and process the stepped portion 14a. Can also.

  In addition, the gap adjusting member 44 prepares a plurality of blocks having different thicknesses in advance, selects a block having a thickness closest to the above-described correction distance, and fixes the block to the truss 16 by a fixing means such as welding. May be. However, it is necessary to select the block body so that the distance obtained by subtracting the thickness of the block body from the first gap G1 is shorter than the above-mentioned margin α2 in order to prevent the truss 16 from falling off.

  In the first embodiment, the gap adjusting members 44 and 46 are provided at the upper floor end 17 of the truss 16, but the gap adjusting members 44 and 46 may be provided at the lower floor end 18.

  In the present embodiment, the escalator 10 has been described as an example of the passenger conveyor. However, the present invention may be applied to an inclined moving sidewalk.

  Subsequently, first to third modified examples of the first embodiment will be described with reference to FIGS. 4 to 6. In the following description, the same components as those in the first embodiment will be denoted by the same reference numerals, and the description thereof will not be repeated, and only different portions will be described.

  FIG. 4 is a partially enlarged view showing a configuration of a gap adjusting member 52 provided in an escalator 50 which is a first modified example of the escalator 10 in the embodiment.

  As shown in FIG. 4, the gap adjusting member 52 is a block body having a screw hole 52a penetrating in the thickness direction provided at the center. On the other hand, through holes 17a and H1 are provided in the upper floor end 17 of the truss 16 and the side 31a of the angle iron 31 at positions facing the concrete beam 12, respectively. The bolts 53 inserted into the through holes 17a and H1 from the upper floor machine room M1 are screwed into the screw holes 52a of the gap adjusting member 52, whereby the gap adjusting member 52 is fixed to the truss 16. Thus, the gap adjusting member 52 may be fixed to the truss 16 using the bolt.

  FIG. 5 is a partially enlarged view showing a configuration of a gap adjusting member 62 provided in an escalator 60 which is a second modification of the escalator 10 in the embodiment.

  As shown in FIG. 5, the gap adjusting member 62 includes a bolt 63 screwed into a through hole 17b of the upper floor side end 17 of the truss 16 and a screw hole H2 provided in the side 31a of the angle iron 31. A fixing nut 64 screwed onto the screw shaft of the bolt 63. The bolt 63 has a function of adjusting the length of a screw shaft protruding from the truss 16 by rotating in the tightening direction or in the opposite direction. The fixing nut 64 is fixed to the side 31 a of the angle iron 31 by tightening the fixing nut 64 in a direction approaching the upper floor end 17 of the truss 16 while holding the bolt 63 so as not to rotate together. It has a function to do.

  According to the gap adjusting member 62, the length of the bolt 63 protruding from the truss 16 can be adjusted. For this reason, the size of the gap between the concrete beams 12, 14 and the truss 16 can be adjusted more flexibly than when the gap adjusting members 44, 46 in the above embodiment are used.

  FIG. 6A is a diagram illustrating a third modification in which the escalator 10 according to the first embodiment is installed on a steel beam 100 instead of the concrete beam 12. FIG. 2B is a cross-sectional view taken along the line BB shown in FIG. As shown in FIGS. 6A and 6B, the upper floor end 17 of the truss 16 may be installed on a steel beam (first support beam) 100. The lower floor end 18 of the truss 16 may be installed on a steel beam similarly to the upper floor end 17.

  As shown in FIGS. 6A and 6B, the steel beam 100 on the upper floor has an H-shaped steel 102 extending in a horizontal direction orthogonal to the longitudinal direction X, and a predetermined interval between the H-shaped steel 102. And reinforcing ribs 104a, 104b respectively attached with a gap. A support plate 106 is mounted on the upper surface of the H-shaped steel 102. The extension plate 32 of the upper floor support member 30 is slidably hung on the support plate 106. Spacers SP1 and SP2 are interposed between the support plate 106 and the extension plate 32 to adjust the position of the truss 16 in the vertical direction.

  On the other hand, the gap adjusting members 44 and 46 are mounted at positions facing the end faces of the reinforcing ribs 104 a and 104 b and the support plate 106. Therefore, when the truss 16 is displaced toward the steel beam 100 on the upper floor, the gap adjusting members 44 and 46 can be brought into contact with relatively high strength portions of the steel beam 100. In this way, the contact force of the gap adjusting members 44 and 46 can be easily received by the steel beam 100.

  If the contact area 17P of the upper floor side end 17 below the side 31a of the angle iron 31 contacts the end face of the support plate 106, the contact height is high due to the high raised height of the spacers SP1 and SP2. The gap adjusting members 44 and 46 may be attached to the area 17P at a position facing the end face of the support plate 106.

  Next, the configuration of the escalator 110 according to the second embodiment of the present invention will be described with reference to FIGS. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will not be repeated. Only the components having different configurations will be described. FIG. 7 is a diagram schematically illustrating the configuration of the escalator 110. FIG. 8A is a partially enlarged view illustrating the configuration of the lower floor end 18 of the truss 16, and FIG. 8B is a partially enlarged view illustrating the configuration of the upper floor end 17 of the truss 16. is there.

  As shown in FIG. 7, the escalator 110 has substantially the same configuration as the escalator 10 shown in FIG. As shown in FIG. 8B, an angle iron 31 is attached to the upper floor end 17 of the truss 16 in the escalator 110, and a side portion 31 a of the angle iron 31 which is a first contact planned portion is provided. The first gap adjusting member 144 is fixed. On the other hand, as shown in FIG. 8A, an angle iron 34 is attached to the lower floor end 18 of the truss 16, and a side 34 a of the angle iron 34, which is a second contact planned portion, is attached to the angle 34. The second gap adjusting member 146 is fixed. Each of the gap adjusting members 144 and 146 may have the same configuration as the gap adjusting member 44 in the first embodiment, or may have the same configuration as the gap adjusting members 52 and 62.

  Here, a method of setting the thickness t1 of the first gap adjusting member 144 and the thickness t2 of the second gap adjusting member 146 will be described with reference to FIGS. 8A and 8B. The thickness t1 of the first gap adjustment member 144 is set to a dimension that matches a first correction distance obtained by subtracting a design value from an actually measured value of the first gap G1. Thereby, the displacement distance when the truss 16 is displaced toward the concrete beam 12 can be reduced by a distance obtained by subtracting the design value from the actually measured value of the first gap G1. Accordingly, the dimension of the extension plate 35 on the lower floor side can be shortened by a length corresponding to the thickness t1.

  Similarly, the thickness t2 of the second gap adjusting member 146 is set to a dimension corresponding to a second correction distance obtained by subtracting a design value from a measured value of the second gap G2. Accordingly, the displacement distance when the truss 16 is displaced toward the concrete beam 14 can be reduced by a distance obtained by subtracting the design value from the actually measured value of the second gap G2. Accordingly, the dimension of the extension plate 32 on the upper floor side can be shortened by a length corresponding to the thickness t2.

  As the first gap adjusting member 144, similarly to the gap adjusting member 44, a plurality of blocks having different thicknesses are prepared in advance, and the block having the thickness closest to the above-described correction distance is selected and the truss 16 is used. You may make it attach to. However, it is necessary to select the block body so that the distance obtained by subtracting the thickness of the block body from the first gap G1 is shorter than the above-mentioned margin α2 in order to prevent the truss 16 from falling off. Similarly, the second gap adjusting member 146 may be selected from a plurality of blocks having different thicknesses.

  According to the escalator 110 in the present embodiment, when the truss 16 is displaced toward the concrete beam 12, the first gap adjusting member 144 abuts on the concrete beam 12, so that the thickness t1 of the first gap adjusting member 144. The displacement distance of the truss 16 can be shortened by a distance corresponding to. For this reason, it is possible to prevent the truss 16 from falling off without providing an unnecessarily long dimension for the extension α2 of the lower floor extension plate 35, and the dimension of the plate corresponds to the thickness t1 of the first gap adjusting member 144. Can be reduced by distance. Accordingly, the dimension of the stepped portion 14a of the concrete beam 14 in the X direction can be shortened by a distance corresponding to the thickness t1, and the labor of cutting the concrete beam 14 and processing the stepped portion 14a can be reduced. it can.

  Similarly, when the truss 16 is displaced toward the concrete beam 14, the second gap adjusting member 146 comes into contact with the concrete beam 14 so that the truss 16 is moved by a distance corresponding to the thickness t2 of the second gap adjusting member 146. Can be reduced. For this reason, it is possible to prevent the truss 16 from falling off without providing an unnecessarily long dimension of the allowance α1 of the extension plate 32 on the upper floor, and the dimension of the plate corresponds to the thickness t2 of the second gap adjusting member 146. Can be reduced by distance. Along with this, the dimension of the stepped portion 12a in the concrete beam 12 in the X direction can be shortened by a distance corresponding to the thickness t2, and the labor for cutting the concrete beam 12 and processing the stepped portion 12a can be reduced. it can.

  The present invention can also be implemented in modes in which various improvements, modifications, or modifications are made based on the knowledge of those skilled in the art without departing from the spirit of the present invention. Further, any technique specifying matter may be replaced with another technique as long as the same operation or effect is generated.

When the truss is displaced toward the second support beam, the truss abuts on the second support beam instead of the second abutment portion, so that the second abutment portion and the second support beam A second gap adjustment member that reduces the displacement distance of the truss by a distance based on a second correction distance obtained by subtracting the design value of the second gap from the actually measured value of the second gap,
Characterized by having
Passenger conveyor.
