SUPPORTING STRUCTURE OF AN ELEVATOR OR MOVING PLATFORM

Description

[0001] The invention relates to a supporting wall element of a supporting structure of an escalator or a moving walkway and to a supporting structure module or supporting structure with such supporting wall elements.

[0002] Escalators and moving walkways typically have a bridge-like supporting structure extending between two support points. If necessary, central supports are provided between the two support points if the span to be bridged is too large and the supporting structure should not be too bulky.

[0003] The supporting structures of very long escalators and moving walkways are typically divided into structural modules to facilitate transport from the manufacturing site to the structure into which the escalator or moving walkway is to be installed. During installation into the structure, the structural modules are rigidly connected to each other in series at their ends, forming a continuous, load-bearing structure into which additional components of the escalator or moving walkway can be installed and attached.

[0004] The load-bearing capacity of the structure is essentially achieved by two load-bearing wall elements that extend parallel to each other in two vertical, spaced-apart planes. The lower edges of the parallel load-bearing wall elements, also called bottom chords, are connected to a floor structure, giving the structure a U-shaped cross-section. To support the load-bearing wall elements against each other and significantly increase the rigidity of the structure, the opposing load-bearing wall elements are additionally connected to each other by cross braces at approximately half the height of the U-shaped cross-section.

[0005] Other components of the escalator or moving walk that are built into the supporting structure include, for example, a circumferentially arranged conveyor belt with pallets or steps, guide rails that guide the conveyor belt, a drive group with a main drive shaft via which the conveyor belt is deflected and driven, a control device by means of which a motor of the drive group can be controlled, formwork parts that cover stationary components such as the supporting structure, but also moving parts of the escalator or moving walkway, and the like.

[0006] To ensure user safety, balustrades, each with a circumferential handrail, are provided on both sides of the conveyor belt. The balustrades extend above the conveyor belt, with their balustrade components typically attached to the upper edge of the supporting structure. Depending on their design and location, the balustrades are subject to high loads, which are primarily directed transversely to the planar extension of the load-bearing wall elements. Due to this design, the aforementioned loads cause high bending moments at the upper edges of the load-bearing wall elements.

[0007] To prevent the supporting structures or structural modules from becoming too heavy, which would otherwise incur high material and transport costs, EP 1 321 424 B1 proposes a structural design whose supporting wall elements are made of sheet metal. The highly stressed zones of this structural design are the aforementioned lower chord and the upper chord running along the upper edge of the supporting wall element. This chord is subjected to compressive stress when the supporting structure is installed in the structure resting on its support points. To prevent the upper chord from buckling under the compressive load, the aforementioned document proposes stiffening it with a square tubular profile. This square profile also has a high area moment of inertia on its own, so it also possesses high torsional rigidity, which is suitable for supporting the bending moments exerted by the balustrade.

[0008] However, the use of a shaped profile such as the aforementioned square tube profile requires a great deal of expensive welding work. Using the example of a cross brace, EP 1 321 424 B1 teaches that buckling stiffness can also be achieved by bending the sheet metal edge. This stiffening option is significantly more cost-effective than welding a shaped profile, but it does pose a certain risk to its torsional stiffness because, when high bending moments occur, the bend is bent upward, thereby reducing the buckling stiffness of the upper chord.

[0009] EP 3 109 196 A1 also discloses the preamble of claim 1 and proposes a modular supporting structure made of very thin, formed sheet metal parts. To achieve the required rigidity, a large number of different components are used, making the assembly of these components very cost-intensive.

[0010] The object of the present invention is therefore to provide a supporting wall element which can be produced cost-effectively and yet ensures a load-resistant fastening of balustrade components.

[0011] This problem is solved by a supporting wall element of a supporting structure of an escalator or moving walkway. The supporting wall element has a side wall part made in one piece from a sheet metal, with a top chord formed by folding at a first longitudinal edge of the side wall part. A side wall of the side wall part extends between the top chord and a second longitudinal edge opposite the first longitudinal edge.

[0012] To ensure that the top chord created by folding is not subjected to excessive loads from the balustrade's bending moments, the supporting wall element has at least one fastening flange for fastening balustrade components of a balustrade. A first region of the fastening flange is firmly connected to the side wall of the side wall part, a second region of the fastening flange projects beyond the top chord orthogonally to its longitudinal extent, and a central region of the fastening flange arranged between the first region and the second region at least partially encloses the section of the top chord present in this region. The bending moments acting on the supporting wall element from the balustrade are thus broadly supported around the top chord in the side wall. In addition, the top chord is stiffened, at least in a form-fitting manner, against bending relative to the side wall by the partial enclosing of the fastening flange in the central region.

[0013] To further stiffen the supporting wall element, a bottom flange can be formed by folding along the second longitudinal edge of the side wall section. The side wall of the side wall section extends between the top flange and the second longitudinal edge or the bottom flange. Preferably, the top flange and bottom flange extend parallel to each other and on the same side of the side wall, giving the side wall section a C-shaped cross-section. This design allows for the construction of escalators and moving walkways that are very narrow relative to the width of the conveyor belt.

[0014] To achieve the lightest possible load-bearing structure, recesses can be provided in the side wall of the load-bearing wall element that are offset from one another, so that connecting struts, also called uprights, are formed between the upper and lower chords, arranged orthogonally to these. In addition, the offset of the recesses also creates diagonal struts that extend between two connecting struts and the upper and lower chords. In other words, the connecting struts and diagonal struts, together with the upper and lower chords, form a truss-like structure. A truss is a structure composed of polygonal frames, such as those found in steel bridges, steel masts, or the Eiffel Tower. The most commonly used frame shape is a triangle.A truss-like structure is therefore a structure that is modeled on a truss and has comparable mechanical and weight-optimized properties to a truss made of steel profiles.

[0015] The cutouts can have any geometric shape, for example, in the shape of a polygon, a teardrop, an ellipse, or even a circle. Polygons such as triangular cutouts preferably have generously rounded corners to optimize the flow of forces within the truss-like structure.

[0016] In one embodiment of the invention, additional components such as connecting plates for cross struts can be arranged on the connecting struts, which also stiffen the connecting struts against lateral buckling. The connecting plate is preferably designed to be shorter in its longitudinal extent than the connecting strut. This stiffens the connecting strut against lateral buckling only in certain sections, but the remaining buckling length of the areas of the connecting strut not stiffened by the connecting plate is sufficiently shortened. The advantage of this shortened stiffening is that the guide rails can be arranged closely adjacent to the side wall. This makes it possible to produce a very narrow escalator or moving walkway. The connecting plates can also be used to attach structural components of a floor structure of the supporting structure.Of course, the connecting struts can also provide fastening areas for other components of the escalator or moving walkway, such as base plates, drive components, guide rails and the like.

[0017] In a further embodiment of the invention, the mounting flange has an L-shaped cross-section along its longitudinal extent. This L-shaped cross-section provides the mounting flange with high rigidity against the bending moments of the balustrade acting on it. Due to the L-shaped cross-section, the mounting flange has two legs.

[0018] In a further embodiment of the invention, the first of the two legs formed by the L-shaped cross-section is arranged with its planar extension in a plane parallel to the side wall of the supporting wall element. The second leg is arranged with its planar extension orthogonal to the side wall and is arranged on the side wall. The second leg can ideally partially enclose or surround the section of the upper chord located in the central area of ​​the fastening flange.

[0019] To facilitate assembly of the load-bearing wall element, the top chord can have a recess that allows for the precise positioning of the fastening flange in its central area. The recess can also increase the cross-section of the second leg and thus the tensile, compressive, and flexural strength of the central area.

[0020] In a further embodiment of the invention, the side wall can have an opening, and the mounting flange can have a matching projection for the precise positioning of the first region of the mounting flange on the side wall. Together with the recess in the upper chord, this allows for precise spatial alignment of the mounting flange on the side wall section.

[0021] The aforementioned means, such as openings, projections, and recesses, also fix the mounting flange in its intended position on the side wall section with a positive fit, while the mounting flange is connected to the side wall section by a material bond, such as by gluing, soldering, or welding. For example, the weld seams can be located not only in the first area, but also between the side wall section and the mounting flange. Weld seams can, of course, also be located in the middle area between the top chord and the mounting flange. This provides additional stiffening for the top chord and the mounting flange.

[0022] To allow parts of the balustrade to be attached above the top chord, the mounting flange can have holes in the second area for the attachment of fasteners. Of course, the balustrade components intended for attachment can also be firmly connected to the mounting flange. However, it has been shown that removable fasteners such as screws, pins, and the like significantly facilitate maintenance and repair in the event of damage to the balustrade, and therefore the aforementioned holes are preferred.

[0023] In a further embodiment of the invention, the mounting flange in the first region can have mounting points for attaching additional components of the escalator or moving walkway, such as handrail support rollers, guide rails, cable ducts, and the like. In a fully assembled escalator or moving walkway, the handrail support rollers serve to return a handrail that runs circumferentially along the balustrade, and the guide rails guide the conveyor belt.

[0024] According to the invention, a supporting structure can be assembled from the previously described supporting wall elements. Such a supporting structure comprises at least two supporting wall elements and at least one cross brace, wherein the cross brace is arranged between the two supporting wall elements and connects them to each other. Furthermore, the supporting wall elements are usually also connected by a floor structure formed from profile bars, which connect the lower chords of the two parallel supporting wall elements. However, the floor structure can also be a closed sheet metal, which is attached to the two lower chords, for example by means of welds. Of course, any combination of sheets and profile bars is also possible.

[0025] Since escalators or moving walkways are often very long, they, or their supporting structures, cannot always be transported in one piece, fully assembled, from the manufacturer's factory to the construction site. To solve this transport problem, the escalator or moving walkway is divided into sections, or their supporting structure into supporting structure modules. Such a supporting structure module has at least two supporting wall elements and at least one cross strut, with the cross strut being arranged between the two supporting wall elements and connecting them to one another. Furthermore, the supporting wall elements have connection points on their front sides, whereby several supporting structure modules designed in this way can be connected in series to one another to form a supporting structure. As already described above with regard to the supporting structure, the supporting structure module can also have a floor structure of the aforementioned type.

[0026] As already mentioned, an escalator or moving walkway has a supporting structure or a supporting structure assembled from supporting structure modules. At least one drive unit, guide rails, and a control system for controlling the drive unit are installed in this supporting structure. Furthermore, a conveyor belt is installed between the supporting walls or supporting wall elements of the supporting structure, which is guided circumferentially by the guide rails and can be driven by the drive unit. The conveyor belt of a moving walkway has pallets, while the conveyor belt of an escalator has steps. Above the supporting structure, at least two balustrades are erected, which can be assembled from balustrade components. The balustrades are arranged on either side of the conveyor belt and attached to the mounting flanges. Of course, further components can be mounted in or on the supporting structure to make the escalator or moving walkway ready for operation.

[0027] Embodiments of the invention are described below with reference to the accompanying drawings, whereby neither the drawings nor the description should be construed as limiting the invention. In the drawings: Figure 1 shows a sectional side view of an escalator having a supporting structure composed of supporting structure modules with fastening flanges for balustrade components; Figure 2 shows a three-dimensional view of one of the Figure 1 shown structural modules; Figure 3 in enlarged view of the Figure 2 indicated section AA; Figure 4 in enlarged, three-dimensional view a fastening flange from the Figure 2 specified viewing direction B.

[0028] The figures are merely schematic and not to scale. The same reference numerals designate identical or equivalent features in the various figures.

[0029] Figure 1shows a schematic side view of an escalator 1 connecting a first floor E1 with a second floor E2 of a building 3. The escalator 1 has a supporting structure 11 composed of four serially connected supporting structure modules 13, 15, 17, 19. The supporting structure 11 is supported on the floors 5, 7 of the floors E1, E2 of the building 3 via two end-mounted support brackets 16 and spans the gap 9 between the floors E1, E2 like a bridge.

[0030] The first supporting structure module 13, located on floor E1, has an access area 21. The fourth supporting structure module 19 also has an access area 23 and is located on floor E2. The second supporting structure module 15 and the third supporting structure module 17 are arranged between the first supporting structure module 13 and the fourth supporting structure module 19 and connect them. For the sake of clarity, only the outlines of the first and fourth supporting structure modules 13, 19 have been shown. The second and third supporting structure modules 15, 17 are shown in more detail and, in the present example, have an identical structure. The supporting structure modules 13, 15, 17, 19 are connected to one another via connection points 31. Detachable connecting elements such as high-strength screws are typically used for this purpose.

[0031] The supporting structure 11 carries all other components of the escalator 1 and supports them on the structure 3. Such components are, for example, a drive unit 41, guide rails 43 and a control system 45 for controlling the drive unit 41. Furthermore, a conveyor belt 25 is arranged between the Figure 2 described supporting wall elements 63, 65 of the supporting structure 11. The conveyor belt 25 of the escalator 1 has steps 27. In a moving walkway, the conveyor belt 25 would have pallets instead of steps 27. The conveyor belt 25 is guided in a circumferentially movable manner by the guide rails 43 and can be driven by the drive unit 41. Above the supporting structure 11, at least two balustrades 51 which can be assembled from balustrade components 53, 55, 57 (due to the arrangement shown in the side view) are arranged. Figure 1only one of the two balustrades 51 is visible), whereby the balustrades 51 are arranged on both sides of the conveyor belt 25 and are fastened to fastening flanges 61 of the supporting structure 11.

[0032] The Figure 2 shows in three-dimensional view the Figure 1 The supporting structure module 17 shown here comprises two supporting wall elements 63, 65 arranged parallel to one another, which differ from one another only in their mirror-symmetrical structure. Each of the two supporting wall elements 63, 65 has a side wall part 67 made in one piece from a sheet metal. An upper chord 69 is formed by folding on a first longitudinal edge 47 of the side wall part 67. A lower chord 71 is also formed by folding on a second longitudinal edge 49 of the side wall part 67, opposite the first longitudinal edge 47. A side wall 73 of the side wall part 67 extends between the upper chord 69 and the lower chord 71.

[0033] As from the Figure 2 As can be seen, the upper chord 69 and the lower chord 71 extend parallel to each other and on the same side of the side wall 73, so that the side wall part 67 has a C-shaped cross-section. This design allows for the construction of escalators 1 and moving walkways that are very narrow in relation to the width of their conveyor belt 25.

[0034] In order to obtain a supporting structure 11 or supporting structure module 17 that is as light as possible, recesses 75, 77, 79 or openings arranged offset from one another can be provided in the side wall 73 of the side wall part 67 in such a way that connecting struts 81 arranged orthogonally to these and diagonally arranged diagonal struts 83 are formed between the upper chord 69 and the lower chord 71.

[0035] The connecting struts 81, also called uprights, and the diagonal struts 83 extend between the upper chord 69 and the lower chord 71 and together with the upper chord 69 and lower chord 71 form a truss-like structure.

[0036] The recesses 75, 77, 79 can have any desired geometric cutout surface, for example, in the shape of a polygon, a drop, an ellipse, or even a circle. Polygons such as the triangular recesses 75 preferably have generously rounded corners to optimize the flow of forces within the lattice-like structure. The sheet metal sections of the recesses 75, 77, 79, cut out, for example, using laser cutting or waterjet cutting processes, can be used to manufacture additional components of the load-bearing wall elements 63, 65, for example, for the connecting plates 85, 89 described below or the fastening flanges 61.

[0037] Further components such as connecting plates 85 for cross struts 87 can also be arranged on the connecting struts 81, which also stiffen the connecting strut 81 against lateral buckling. Preferably, the connecting plate 85 is designed to be shorter in its longitudinal extent than the connecting strut 81. As a result, the connecting strut 81 is only stiffened against lateral buckling in certain sections, but the remaining buckling length of the areas of the connecting strut 81 not stiffened by the connecting plate 85 is sufficiently shortened. The advantage of this shortened stiffening is that the Figure 1 The guide rails 43 shown can be arranged closely adjacent to the side wall 73. This allows a very narrow escalator 1 or a very narrow moving walkway to be produced.

[0038] The cross struts 87 are arranged between the two supporting wall elements 63, 65 and firmly connect them to the supporting structure module 17.

[0039] In the area of ​​the lower chord 71, connecting plates 89 are also welded in, which serve to attach structural parts 91, indicated by a broken line, of a floor structure of the supporting structure module 17. In addition, the two lower chords 71 ​​of the two supporting wall elements 63, 65 are connected to each other with a floor plate 93, so that the supporting structure module 17 has a U-shaped cross-section. In order for the supporting wall modules 13, 15, 17, 19 (see also Figure 1 ) can be connected to one another to form a supporting structure 11, the supporting wall elements 63, 65 have connection points 95 on the front side.

[0040] In order to prevent the upper chord 69 created by bending from being excessively stressed by bending moments of the balustrade 51, each of the supporting wall elements 63, 65 has several fastening flanges 61 for fastening balustrade components 53, 55, 57 of the Figure 1 shown balustrade 51.

[0041] Such a mounting flange 61 is in the Figures 3 and 4 which is why they are described together below. Figure 3 shows the mounting flange 61 according to the Figure 2 indicated section AA in enlarged view, the Figure 4 in an enlarged, three-dimensional view a fastening flange 61 from the Figure 2 specified viewing direction B.

[0042] The fastening flange 61 is designed such that a first region 101 of the fastening flange 61 is firmly connected to the side wall 73 of the side wall part 67. A second region 103 of the fastening flange 61 projects beyond the upper chord 69 orthogonally to its longitudinal extent, and a central region 105 of the fastening flange 61, arranged between the first region 101 and the second region 103, encloses or at least partially surrounds the section 107 of the upper chord 69 present in this region 105. So that the upper chord 69 can project through the fastening flange 61, the fastening flange 61 has a gap 123 in the central region 105.

[0043] The mounting flange 61 also has an L-shaped cross-section along its longitudinal extent L. This L-shaped cross-section provides the mounting flange 61 with high rigidity against the bending moments M of the balustrade 51 acting on it. Due to the L-shaped cross-section, the mounting flange has two legs 125, 127.

[0044] The first of the two legs 127 formed by the L-shaped cross-section is arranged with its planar extension in a plane parallel to the side wall 73 of the side wall part 67. The second leg 125 is arranged with its planar extension orthogonal to the side wall 73 on the side wall part 67. By means of the second leg 125, the section 107 of the upper chord 69, which is present in the central region 105 of the fastening flange 61, can be partially enclosed or projected around in an ideal manner.

[0045] The Figure 4The column-shaped balustrade component 55 of the balustrade 51 shown can be mounted to the second region 103 of the fastening flange 61 by means of fastening means 109 such as screws, pins, split pins, or rivets. For this purpose, bores 141 are provided in the second region 103 of the fastening flange 61. Because the fastening flange 61 projects around the upper chord 69, bending moments M of the balustrade 51 acting on the fastening flange 61 are guided around the upper chord 69 and broadly supported in the side wall 73. In addition, the upper chord 69 is stiffened, at least in a form-fitting manner, against bending relative to the side wall 73 by the partial enclosure of the fastening flange 61.

[0046] To facilitate the assembly of the load-bearing wall elements 63, 65, the upper chord 69 can have a recess 121, which serves to precisely position the fastening flange 61 in its central region 105. The recess 121 also allows the gap 123 to be shortened, or the cross-section of the second leg 125 to be reduced, thus increasing the tensile, compressive, and flexural strength of the central region 105.

[0047] In addition, the side wall 73 can have an opening 129 and the fastening flange 61 can have a matching projection 131 for the exact positioning of the fastening flange 61 in the first region 101. Together with the recess 121 of the upper chord 69, this allows for a precise spatial alignment of the fastening flange 61 on the side wall part 67.

[0048] The aforementioned means, such as openings 129, projections 131, and recesses 121, also fix the fastening flange 61 in its intended position in a form-fitting manner on the side wall part 67, while the fastening flange 61 is connected to the side wall part 67 in a materially bonded manner, such as by gluing, soldering, or welding. For example, the weld seams can be arranged not only in the first region 101, but between the side wall part 67 and the fastening flange 61. Weld seams can of course also be arranged in the central region 105 between the upper flange 69 and the fastening flange 61.

[0049] As indicated by elongated holes 135 and locking lugs 137, the mounting flange 61 in the first area 101 can also have fastening points for attaching additional components of an escalator 1 or a moving walkway. Such components can be, for example, brackets with guide rollers or the cable duct 139 indicated by a dashed line.

[0050] Although the Figure 1 an escalator 1, it is obvious that the supporting walls 63, 65 according to the invention can also be used for a supporting structure 11 of a moving walkway.

[0051] Finally, it should be noted that terms such as "having," "comprising," etc., do not exclude other elements or steps, and terms such as "a" or "an" do not exclude a plurality. Furthermore, it should be noted that features or steps described with reference to one of the above embodiments may also be used in combination with other features or steps of other embodiments described above. Reference signs in the claims are not to be considered as limitations.
