SUPPORTING STRUCTURE FOR A TRAVEL DEVICE

Description

Technical area

[0001] The present invention relates to a support structure for a guideway device, in particular an escalator device, comprising at least one side wall unit, wherein the side wall unit has a plurality of structural elements and / or structural sections. Furthermore, the present invention relates to a longitudinal section module of a modularly assembled guideway device, in particular an escalator device, comprising such a support structure, a corresponding guideway device, and a method for assembling and / or maintaining a device such as the aforementioned guideway device. Background of the invention

[0002] Support structures for guideway devices, or rather, guideway devices themselves, are generally known from the prior art. Support structures form the outer framework for components of the guideway device, such as guides with steps / pallets embedded therein, drives and electrical systems, as well as for attachment and cladding elements. They are typically formed from two opposing sidewall units connected by crossbeams. The sidewall units typically comprise welded profiles as structural elements, from which lattice-like sidewalls and an upper and lower chord are formed.

[0003] Such support structures have relatively large manufacturing tolerances, which are primarily due to the welding of the profiles. Components of the guideway device that are attached to the support structure must therefore be positioned and / or aligned using very complex procedures with appropriate assembly aids before being attached to the support structure. For this purpose, appropriate fastening devices are designed for variable positioning / alignment of the component relative to the support structure and / or must be laboriously created manually after positioning and / or alignment.

[0004] EP 1 321 424 B1 discloses a supporting structure for an escalator or moving walkway, which comprises a truss element formed as a single piece and formed as a flat, unprofiled, cut plate. This reduces the welding work required for the construction of the supporting structure.

[0005] From CN 109 502 462 A, which discloses the preambles of claims 1 and 11, an escalator is also known in which components are attached to reference plates in order to be able to replace the components in an escalator installed in a building without having to replace the entire escalator. Description of the invention

[0006] Based on this situation, it is an object of the present invention to enable a simplified and safe positioning / alignment of components of a guideway device.

[0007] The object of the invention is achieved by the features of the independent main claims. Advantageous embodiments are specified in the subclaims. To the extent technically feasible, the teachings of the subclaims can be combined arbitrarily with the teachings of the main and subclaims.

[0008] In particular, the object is accordingly achieved by a support structure for a guideway device, in particular an escalator device, comprising at least one side wall unit, wherein the side wall unit has a plurality of structural elements and / or structural sections, wherein at least one structural element / structural section has at least one fastening means for fastening a defined-shaped position marker, wherein the at least one fastening means is positioned in a defined manner relative to a reference point of the support structure and wherein the at least one fastening means is positioned on the structural element / structural section in such a way that a defined-shaped position marker fastened thereto marks a position of a component of the guideway device.

[0009] Advantageous aspects of the claimed invention are explained below, and preferred modified embodiments of the invention are further described below. Explanations, particularly regarding advantages and definitions of features, are essentially descriptive and preferred, but not limiting, examples. If an explanation is limiting, this will be expressly stated.

[0010] For the purposes of this disclosure, the general term "guideway device" primarily refers to escalator devices and moving walkway devices (the latter particularly in a stepless configuration with an at least approximately level alignment or with a negligible gradient), as well as related passenger transport devices with a continuously rotating transport device. A guideway device comprises, for example, segments or units forming the transport device, in particular steps or pallets, which are connected by driven chains or similar drive means and guided in guides.The guides, a chain (or a similarly acting traction device), and other components of the guideway device are held, for example, within support structures extending longitudinally, essentially laterally, which are usually formed from two opposing sidewall units connected to each other via crossbeams and, optionally, a floor unit. The term "guideway device" also refers in particular to modularly constructed guideway devices, which are modularly constructed from several longitudinal sections or longitudinal section modules, each with an individual or individually created support structure, and which can be assembled / mounted in modules.

[0011] The supporting structure of the guideway device or of the respective module is preferably formed essentially by opposing side wall units and cross members (also referred to as cross bars) connecting them, wherein each side wall unit is formed by at least one side wall and in particular by an upper chord and / or a lower chord. The modular manufacturing process described here can also comprise the connection of a floor unit to the side wall units, but it has been shown that such a floor unit does not necessarily have to fulfil a supporting function, but is designed, for example, with the function of collecting oil from a / the drive and, if necessary, draining it away, or with regard to a cover and / or accessibility from below to the supporting structure oris designed to be optimized for the guideway device; in this respect, the floor unit is to be understood as an optional structural unit which can also be functionally provided separately from the supporting structure, but which can optionally also assume an additional supporting load-bearing function if desired in individual cases.

[0012] The term "sidewall" refers to a side structure that, for example, runs flat in only one side plane, at least in part, but is alternatively or additionally formed and / or reinforced at least in part by profiles, struts, or beams extending beyond one or more side planes. Generally, the sidewall is formed from structural elements or structural sections that, as flat structural sections, absorb forces in multiple directions and / or, as rod-shaped or strut-like structural elements / sections, absorb the respective forces only along the longitudinal extent determined by their orientation (tension or compression). The sidewall is thus designed, for example, as a closed surface, as a pure framework, or as a structure with portions of closed surfaces and portions with a framework structure.Optionally, at least some of the structural elements / sections of the side wall are formed from flat material, in particular sheet metal, e.g. structurally flat sections or stiffening (in particular) curved L- or U-profile sections in the area of ​​welded connections to other structural elements / sections.

[0013] According to the present disclosure, a "sidewall unit" comprises the above-described sidewall as well as chords assigned to this sidewall as further structural elements / sections, in particular an upper chord and a lower chord. The chords can be formed integrally with the sidewall, integrated, or separate from one another. These chords are alternatively referred to as bands. The respective sidewall / unit can also be understood as a sidewall / unit provided in modules, depending on the reference to a / the respective phase of the manufacturing process of the individual modules or of the entire guideway device. In this respect, the term "sidewall unit" can refer to the entire side structure comprising the upper and lower chords, and the term "sidewall" can refer to the side structure arranged between the upper and lower chords.

[0014] The terms upper chord and lower chord, which together are also referred to as chords, refer to structural elements or structural sections extending longitudinally in the region of an upper edge or a lower edge of the side wall for absorbing loads in the longitudinal direction of the guideway device, in particular bending loads that primarily lead to tensile stresses in the lower chord and compressive stresses in the upper chord. For this purpose, the chords are preferably designed as profiles or profile sections, in particular as L-profiles, U-profiles, or hollow profiles, and thus have a favorable area moment of inertia for absorbing the bending loads. The chords thus stiffen the supporting structure and form outer corner points, with the chords and / or the side walls optionally serving to attach further components of the guideway device.The chords can also be designed as components separate from the side wall; however, at least some of the chords are preferably formed integrally with the side wall, for example by bending the side wall. The upper chord is particularly preferably designed as a hollow profile with four walls, two walls being formed by the L-shaped side wall, which is made from flat material in this area, and two further walls being formed by a flat material component that is also L-shaped and separate from the side wall. Furthermore, the lower chord is preferably designed in a similar manner as a hollow profile with four walls, two walls being formed by the L-shaped side wall, which is made from flat material in this area, and two walls being formed by the floor unit, which is also L-shaped and made from flat material in this area. The components forming the walls are preferably welded together.The upper chord and / or the lower chord can also be provided entirely in one piece with the side wall or entirely separately from the side wall (particularly in the sense of a process variation).

[0015] The general term "components" refers to all parts of the respective guideway devices, in particular the supporting structure or parts thereof and elements to be mounted in the guideway device or the respective modules of the guideway device, e.g. relating to electrical systems, drive, guidance, attachment / cladding elements or the like.

[0016] A fastening means is understood to be a means that enables a positive, force-fitting, or material-locking connection with an element to be arranged thereon, thereby determining the positioning of the element on the element having the fastening means. Such a connection can be made directly between the elements or by means of a connecting means such as screws, pins, or rivets. In particular, the fastening means is designed as a simple recess, in particular as a through-hole, wherein an element received in the recess or a corresponding connecting means engages in the recess and is thus determined in its position with high precision.

[0017] A position marker is understood to be an element by means of which a position, in particular a position in a reference frame, can be recognized. For this purpose, the position marker extends, for example, to the position and directly bears the marking, or the position marker merely points to the position. The position can, for example, be readable from / by the position marker, deducible, or directly attackable, for example by means of an additional fastening means provided there. With regard to the defined shape of the position marker, the at least one fastening means is positioned relative to the reference point of the supporting structure in such a way that the desired position can be recognized through interaction with the defined-shaped position marker.

[0018] Defined positioning means that during production of the guideway device or the support structure the elements which are positioned in a defined manner relative to one another are only positioned with reference to one another. If an element such as a recess, a fastening means or a connecting means is positioned in a defined manner relative to the reference point, only the distance from the reference point is taken into account during production. Any dimensional inaccuracies of other components / elements are then irrelevant for the positioning of the element. A reference point is understood to be a material point on a component relative to which positioning is possible with dimension accuracy in at least one spatial direction. This could be, for example, an edge or corner of a component, a connecting means provided on the component and / or a recess or projection provided in the component.In particular, a round recess is provided as a reference point, which is defined as a reference point by its center and enables the engagement of an assembly aid such as a holder or a gauge.

[0019] The solution to the problem with the support structure described above now involves providing a fastener for a position marker on the structural elements. When providing the fastener, it is positioned relative to the reference point with high precision / low tolerance, so that ultimately the position marker, which is accommodated on the fastener with very tight tolerances, is also positioned relative to the reference point with correspondingly high precision. The fastener is positioned during the manufacture of the support structure in such a way that any manufacturing tolerances that may occur in the supporting structure are avoided. For example, the fastener is not positioned until the supporting structure has already been fully assembled in the process steps that negatively influence the manufacturing tolerance.For example, the fastener is only attached to / attached to a supporting structure made up of individual structural elements after welding. Alternatively, a manufacturing process is selected for the supporting structure that allows the fastener to be positioned directly on a raw material or semi-finished product without subsequently losing the reference point. For example, the fastener is provided on the same semi-finished product as the reference point and positioned with the appropriate precision relative to the reference point.

[0020] The present teaching advantageously achieves that components can be positioned and / or aligned reliably and easily using the position marker. The components are then indirectly positioned and aligned relative to the reference point and thus their position is determined. A complex method for positioning components can then be dispensed with. In particular, this also enables the reliable positioning of several components relative to one another if they are all positioned relative to a position marker related to the reference point or relative to the reference point.

[0021] The present teaching further achieves the ability to mark a position located away from the supporting structure. For example, this is a position midway between the two side wall units or in the area of ​​a free space between lattice-like structural elements / sections. In particular, a position marker directed toward or extending to such a position, provided it is releasably attached to the fastening means, can only be temporarily attached to the fastening means, so that the position marker is removed again after positioning and / or aligning the component and does not hinder the assembly of further components. In particular, the position marker can be reattached to the fastening means at a later time, for example during maintenance.

[0022] In a preferred embodiment, the support structure comprises two fastening means as a pair of fastening means for attaching the position marker. The position of the position marker attached to the fastening means is then statically determined in at least one plane. For example, the plane in which the position marker is statically determined corresponds to a sidewall plane or is parallel to it.

[0023] In a further preferred embodiment, the at least one fastening means is designed for selectively fastening the position marker to an inner and / or an outer side of the support structure. For example, the fastening means for this purpose is designed as a through-hole, as a pin penetrating the structural element / structural section, or is split in two with respective fastening means on both sides of the structural element / section. This advantageously ensures that the position marker can be used to mark the position during assembly or maintenance, regardless of whether the work is carried out from inside and / or outside the support structure. It can also be provided that a position marker can be fastened to the fastening means both inside and outside at the same time.

[0024] Preferably, the at least one fastening means is designed as a recess, in particular as a through-hole. Such a recess can be formed easily and with very precise tolerances with respect to the reference point on the support structure. Furthermore, it is possible to attach the position marker to the fastening means in a simple manner—and in the case of a through-hole, from both sides of the support structure—for example, using screws, pins, rivets, or the like. Alternatively, the at least one fastening means is designed, for example, as a pin, bolt, or the like.

[0025] Furthermore, a fastening means designed as a recess is preferably formed by laser cutting. The material is thus severed by a correspondingly aligned and designed laser beam. A (corresponding) laser cutting tool is designed in particular for processing flat material, wherein a laser head is aligned perpendicular to the flat material and is designed to be movable relative to the flat material in a plane parallel to the flat material. The laser head can also be oriented deviating from its vertical orientation. A laser cutting tool can also comprise a laser head that is spatially movable around a workpiece, in particular a profile. Laser cutting advantageously makes it possible to position the recess with the particularly high precision typical for laser cutting processes and with a particularly low tolerance relative to the reference point.

[0026] In a particularly preferred embodiment, the sidewall unit is formed at least partially from a flat material, in particular from a metal sheet. In particular, the sidewall is formed from such a flat material. In this regard, the present disclosure is based, in particular, on the concept that at least a substantial portion of a sidewall, an upper chord, a lower chord, and / or the entire sidewall unit, which portion defines the overall shape, is formed from the flat material, wherein the reference point is / is preferably defined on the flat material.Thanks to machining methods with very tight tolerances currently available for flat materials, particularly machining using laser cutting tools, the reference point can be referenced during the further assembly of the guideway device, so that assembly can be carried out with very small assembly tolerances and the guideway device can be manufactured with advantageously high dimensional accuracy. In this way, the comparatively precise relative or absolute positioning of individual components of the guideway device with reference to the reference point is also enabled, and additional measures for aligning and positioning the components, particularly relative to one another, can largely be eliminated. This applies in particular to the at least one fastening means and the components positioned / aligned using the position marker.

[0027] Furthermore, the disclosure preferably also includes the teaching of introducing further references, in particular corresponding recesses (in the sense of additional component-specific assembly reference points), into the flat material in addition to the reference point arranged in particular in the corresponding side wall and the fastening means during the same processing method, at which further components can be arranged directly and thus in a defined position relative to at least one (master) reference point with high precision. The references are also introduced in particular in regions of the flat material that can be subjected to further processing steps, in particular bending processes, following the aforementioned processing method, whereby the referencing concept described here can also be implemented for multidimensional positioning in space with respect to at least two or all three spatial directions.The described referencing system also has the advantage of creating a particularly light supporting structure compared to the usual truss construction.

[0028] Furthermore, the disclosure includes the teaching that the reference point is defined by, for example, a circular recess or by its center point, to which further positioning devices (i.e. assembly aids such as, for example, side support units) for positioning individual longitudinal sections or components can be clamped. In particular, the respective component with the reference point or the entire module or even the entire guideway device is lifted at at least one reference point or supported about a reference axis formed by several reference points, e.g. also suspended from it, lifted from it or tilted around it. At least a substantial portion of an upper chord or a lower chord can also be formed from a profile, wherein corresponding machining methods, in particular tube laser cutting methods, for forming a reference point and / or further references are also available for profiles with corresponding accuracy.

[0029] In one refinement of the aforementioned embodiment, structural sections are formed on the flat material by means of cutouts. Providing cutouts advantageously reduces the weight of the side wall unit and allows access through the side wall for the installation of the guideway device. For example, free spaces of a truss structure are cut out on the flat material, so that remaining structural sections are designed in the manner of truss struts. In particular, in this way, the side wall is divided into fields along its longitudinal extent, with structural posts arranged in a vertical direction between the fields and diagonal struts, each as structural sections, between the structural posts.These structural sections can also be supplemented or partially replaced by (attached) structural elements, in particular profiles, wherein the one-piece flat material preferably forms the essential basic structure of the side wall / unit and thus a fastening means arranged therein and / or references arranged therein are in a defined relationship to the reference point.

[0030] The recesses are preferably formed by laser cutting. This is particularly advantageous when the flat material for forming the fastening means, the reference point, and / or other references is already being processed in a laser cutting tool. A plurality of processing steps are then carried out together with high precision and tight tolerances, advantageously reducing the number of separate processing steps.

[0031] Particularly preferably—and as already essentially described above—the at least one fastening means is formed as a recess in the flat material by laser cutting, and the flat material further comprises the reference point as a recess formed by laser cutting. In this way, positioning of the fastening means relative to the reference point, which is also formed on the flat material, is achieved with particularly tight tolerances or with the particularly high precision typical for laser cutting.

[0032] In one embodiment, the at least one fastening means is positioned on the structural element / structural section in such a way that a defined-shaped position marker attached thereto marks a position of a center of the guideway device and / or a position of a center of a component of the guideway device, in particular the support structure or the side wall unit. Based on a marked center of the guideway device or one of the aforementioned components, the positioning and / or alignment of further components can then take place. The marked center thus serves as a general reference point. In further embodiments, the at least one fastening means is positioned on the structural element / structural section in such a way that a defined-shaped position marker attached thereto marks a position of an axis of rotation of a component of the guideway device, a position of a guide, a position of a handrail and / or the position of a comb plate.

[0033] The object is further achieved by a support structure for a guideway device, in particular an escalator device, comprising at least one side wall unit, wherein the side wall unit is formed at least partially from a flat material, in particular from a metal sheet, wherein the side wall unit has a plurality of structural elements and / or structural sections, wherein at least one structural element / structural section has at least one defined position marker for marking a position of a component of the guideway device, and wherein the position marker is formed as a recess and is positioned in a defined manner relative to a reference point of the support structure. In this solution, the position marker is therefore formed directly as a recess in the flat material and is positioned in a defined manner relative to the reference point.The defined positioning can be achieved in the same way as described above with regard to the fastening means, for example, by forming the position marker by laser cutting. Furthermore, for example, the position marker is designed as an arrow-shaped recess and extends through the flat material, so that it can be recognized and used from both sides of the side wall unit. In this respect, the same advantages can be achieved with the support structure as with the support structure described above. Embodiments described with regard to the support structure described above can be designed accordingly for a support structure with a position marker designed as a recess.

[0034] The object is further achieved by a longitudinal section module of a modularly assembled guideway device, in particular an escalator device, comprising a support structure as described above. The term "longitudinal section module" is generally understood within the meaning of the present disclosure as a longitudinal module of the guideway device, i.e., as a module that forms a longitudinal or longitudinal section of the guideway device (i.e., a component that is at least structurally complete in the corresponding length range). This term therefore encompasses the terms "head module" and "intermediate module." The term "head module" refers to a module arranged at one of the ends of the guideway device and refers optionally to both types of head modules (upper and lower head modules, also referred to as upper part and lower part); thus, this term can equally refer to the module at the upper or lower end of the guideway device.Head modules typically extend across the inclination angle of the guideway device, thus spanning the bend or transition from the inclined longitudinal section to the respective horizontal section. In this context, the term "platform section" refers to the section of the respective head module that, when properly arranged, is aligned at least approximately in a horizontal plane. Therefore, when describing the arrangement / orientation of the respective head module, reference is also made to the orientation of this platform section (or its main extension plane), particularly if the absolute length of the platform section is greater than the absolute length of the inclined section.The term "connecting inclined section," also referred to in the literature as a stub, is also to be understood in particular as the inclined / inclined section intended for connecting / marrying with another longitudinal section module. Depending on the function of the respective head module, it can be more or less long. This means that the individual modules are intended to be connected to one another in the area of ​​an inclined longitudinal section. The general term "longitudinal section" can refer either to a longitudinal section module or to a specific longitudinal section, particularly of the head module (i.e., the platform section or inclined section).

[0035] Such a longitudinal section module accordingly exhibits the advantages described above with regard to the support structure. In particular, in a longitudinal section module, a connecting means for connecting the longitudinal section module to another longitudinal section module serves as the reference point, or the fastening means and the connecting means are positioned relative to the same reference point. The further longitudinal section module can then have a corresponding absolute reference point or reference an absolute reference point of the longitudinal section module, wherein the absolute reference point is preferably also referenced during assembly of the guideway device. In particular, the connecting means and the fastening means are incorporated into the longitudinal section module by laser cutting.

[0036] The object is further achieved by a guideway device, in particular an escalator device, comprising a support structure as described above. In particular, the guideway device has at least one longitudinal section module as described above. Such a guideway device accordingly exhibits the advantages described above with respect to the support structure or the longitudinal section module.

[0037] Ultimately, the object is also achieved by a method for assembling and / or maintaining a previously described guideway device, wherein a position marker for marking a position of a component of the guideway device is arranged on the at least one fastening means and is subsequently removed from the at least one fastening means after the positioning and / or alignment of a component assigned to the position. In this way, it is achieved that a position can be attached to the support structure for the positioning / alignment of a component when needed, but is not attached there precisely when it would hinder further work steps, in particular the assembly of further components.Preferably, the position marker is arranged optionally on the inside and / or the outside of the support structure, so that processing from the inside and / or the outside with referencing of the position is equally convenient. Short description of the drawings

[0038] The invention will be explained in more detail below with reference to preferred embodiments and the accompanying drawings. The term "figure" is abbreviated to "Fig."

[0039] The drawings show Fig. 1a a perspective view of a partially assembled head module of a modularly assembled guideway device with a support structure; Fig. 1b a perspective view of a partially assembled intermediate module of a modularly assembled guideway device with a support structure; Fig. 1c a perspective view of another partially assembled head module of a modularly assembled guideway device with a support structure; Fig. 1d a detailed view of a support structure according to the Fig. 1a to 1c ; Fig. 2a a perspective view of a side wall unit of a support structure for a guideway device according to a preferred embodiment; Fig. 2b a detailed view of the side wall unit according to Fig. 2a with attached position markers; Fig. 2c a detailed view of a position marker according to Fig. 2b ; and Fig. 2a detailed view of the side wall unit according to Fig. 2a with another position marker attached to it. Detailed description of the drawings

[0040] The described embodiments are merely examples that can be modified and / or supplemented in a variety of ways within the scope of the claims. Each feature described for a specific embodiment can be used independently or in combination with other features in any other embodiment. Each feature described for an embodiment of a specific claim category can also be used correspondingly in an embodiment of a different claim category.

[0041] The Figures 1a to 1c show several longitudinal section modules 1.1, 1.2, 1.3 of a modularly assembled guideway device 1, namely Figure 1a a first longitudinal section module 1.1 designed as a lower head module, Figure 1b a second longitudinal section module 1.2 designed as an intermediate module and Figure 1ca third longitudinal section module 1.3 designed as an upper head module. The head modules extend beyond the kinks or have a bent stub. The longitudinal section modules 1.1, 1.2, 1.3 each have a supporting structure 2 with two side wall units 2.1, 2.2 extending mainly in a longitudinal direction L and cross beams 2.3 extending in a transverse direction Q. Each side wall unit 2.1, 2.2 in turn has a side wall 3, an upper chord 4.1 extending in the longitudinal direction L, and a lower chord 4.2 extending in the longitudinal direction L.

[0042] The structure of the supporting structures 2 is in the Figure 1dshown in detail. The side wall 3 is formed from a flat material in which structural sections 6.1 and structural sections 6.2 are formed through recesses 5. The structural sections 6.1 thus divide the side wall 3 or the side wall units 2.1 into sections. Furthermore, structural posts 7 with supporting elements 7.1 and the cross struts 2.3 are arranged or attached, in particular welded, to the structural sections 6.1.

[0043] The side wall 3 is further formed integrally with the upper chord 4.1 and the lower chord 4.2. Thus, a first wall 8.1 is formed by the flat material forming the side wall 3, and a second wall 8.2 of the upper chord 4.1 is bent in an L-shape from the first wall 8.1. A third wall 8.3 and a fourth wall 8.4 of the upper chord 4.1 are formed by a further element made from an L-shaped bent flat material and welded to the flat material forming the side wall 3. In the same way, a first wall 9.1 is formed by the flat material forming the side wall 3, bent in an L-shape from the side wall 3, and a second wall 9.2 of the lower chord 4.2 is bent in an L-shape from the first wall 9.1. A third wall 9.3 and a fourth wall 9.4 of the lower chord 4.2 are formed by an L-shaped bent floor unit 10.

[0044] Again with reference to the Figures 1a to 1cThe longitudinal section modules 1.1, 1.2, 1.3 are shown with several components of the guideway device. The lower head module ( Fig. 1a ) a comb plate 12, a base 13, a balustrade 16 with a handrail 17 arranged thereon, and several guides 14.1, 14.2, 14.3 for chain rollers, step / pallet rollers and / or a handrail (not shown). Corresponding guides 14.1, 14.2, 14.3, a base 13, and a balustrade 16 are also provided in the intermediate module ( Fig.1b ). The guides 14.1, 14.2, 14.3 rest on the supporting elements 7.1. The upper head module ( Fig. 1c ) In addition to the components already present in the lower head module and / or intermediate module, it has a drive 15 for driving a chain and / or a handrail loop. The illustration of the upper head module does not depict a balustrade 16.

[0045] The longitudinal modules 1.1, 1.2, 1.3 each have reference points 18 on the supporting structures 2, or side wall units 2.1, 2.2, or side walls 3 in the flat material, which in Fig. 1d are shown. In the Figures 1a to 1cthe reference points 18 are covered by mounting brackets 19, which in turn are fastened to slides 20. By suspending the longitudinal sections 1.1, 1.2, 1.3 from the reference points 18, it is possible to refer to the reference points 18 repeatedly during assembly and, ideally, exclusively when positioning / aligning components. The reference points 18 are formed on the flat material by laser cutting during the manufacture of the side walls 3, whereby, thanks to the accuracy typical of laser cutting, all other recesses or cutouts made in the flat material are positioned exactly opposite the reference points 18 and can therefore in turn serve as references when positioning / aligning components. This applies in particular to connecting means 21 provided for connecting the longitudinal section modules 1.1, 1.2, 1.3 and slots 22 for receiving components of the guideway device 1, such as the support elements 7.1.By means of the reference points 18 and in particular the suspension of the longitudinal section modules 1.1, 1.2, 1.3, an exact alignment of the longitudinal section modules 1.1, 1.2, 1.3 to one another is also possible when they are connected to one another via the connecting means 21.

[0046] Figure 2a shows a side view of the side wall unit 2.1 of an upper head module. Fastening means 30 formed as recesses are arranged at various structural sections 6.1, 6.2. The fastening means 30 are provided in pairs and are positioned in a defined manner relative to the reference points 18 by laser cutting the flat material forming the side wall 3.

[0047] In the Figures 2b and 2cA first embodiment of position markers 31 is shown, which are attached to the fastening means 30 or, in the illustration, are only positioned on the fastening means 30 for fastening with connecting means such as screws. The position markers 31 are arrow-shaped and each mark the position of a rotational axis 32 of a drive 15 in a spatial direction. The two position markers 31 then define or mark the position of the rotational axis 32 in the plane of the side wall 3, wherein the rotational axis 32 lies in the region of a recess 5 and thus in a free space between the structural sections 6.1, 6.2. The position markers 31 also have handles 33 for simplified handling.

[0048] Figure 2dshows a further embodiment of a position marker 35 when attached to a fastening means 30, wherein the position marker 35 extends to the position 36 to be marked and marks it by means of a recess arranged there. The fastening means 30 associated with the position marker 35 is formed by two round holes and one elongated hole, wherein a pin 36 provided on the position marker 35 is associated with the elongated hole.

[0049] Both the position markers 31 and the position marker 35 can be attached to the fastening means 30 from inside and / or outside the support structure 2.
