Definitions

  • the present invention relates to a load-bearing device for supporting a load on a profile, in particular on an upper chord of a supporting structure of a guideway device.
  • the invention further relates to an adapter element and a receiving element of such a load-bearing device, a supporting structure with such a load-bearing device and a guideway device with such a supporting structure.
  • Balustrades are usually held on load-bearing devices that are arranged on an upper chord of the side wall unit(s) and serve as fall protection for passengers on the travel path device and/or to limit the travel path area to the sides.
  • Such balustrades and associated load-bearing devices are designed to support the load of several passengers who press or fall against the upper end of the balustrade with their body weight.
  • the disadvantage is that load-bearing devices for meeting these design requirements are often very large and heavy and take up a relatively large amount of the limited space available on the supporting structure.
  • load-bearing devices are often complex to install and/or complex to align for a desired positioning of the balustrade panels.
  • the object is accordingly achieved by a load-bearing device for receiving a load on a profile, in particular on an upper chord of a support structure of a guideway device, the load-bearing device having an adapter element with a first leg assigned to a first side of the profile and a second leg assigned to a second side of the profile and a receiving element, wherein the adapter element has a first projection on the first leg for positioning the adapter element on a first recess of the profile and a second projection on the second leg for positioning the adapter element on a second recess of the profile, wherein the receiving element can be connected or is connected to the first leg of the adapter element at a first connection point and to the second leg of the adapter element at a second connection point, and wherein a load receiver is formed on the receiving element.
  • guideway device refers primarily to escalator devices and moving walkway devices (the latter in particular in a stepless design in an at least approximately flat 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, steps or pallets forming the transport device, which are connected to driven drive means and guided in guides.
  • the guides as well as the drive means and other components of the guideway device are usually held within support structures extending longitudinally essentially laterally therefrom, which are usually formed from two side wall units lying opposite one another and connected to one another via crossbeams and optionally also a floor unit.
  • 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.
  • the supporting structure of the guideway device or the respective module is preferably formed essentially by opposing side wall units and cross beams connecting them (also referred to as crossbars), whereby a respective side wall unit is formed by at least one side wall and in particular by an upper chord and/or a lower chord.
  • a supporting structure can also comprise a floor unit; however, it has been shown that such a floor unit does not necessarily have to fulfil a supporting function, but can, for example, be used with regard to the Function is designed to collect oil from a drive and drain it away if necessary, or is designed to be optimized with regard to coverage and/or accessibility from below to the support structure or the guideway device.
  • the floor unit is to be understood as an optional structural unit which can also be functionally provided separately from the support structure, but which can optionally also take on an additional supporting load-bearing function if desired in individual cases.
  • side wall refers to a side structure of the supporting structure, which, for example, runs flat in only one side plane at least in sections and/or is formed and/or reinforced at least in sections by profiles, struts or supports that extend beyond the side plane.
  • the side wall is made up of structural elements or structural sections that, as flat structural sections, absorb forces in several directions and/or, as rod-shaped or strut-like structural elements/sections, absorb the respective forces only along the longitudinal extension specified by the orientation.
  • the side wall is therefore designed, for example, as a closed surface, as a pure framework or as a structure with parts of closed surfaces and parts with a framework structure.
  • a side wall unit comprises the side wall described above and belts assigned to this side wall as further structural elements/sections, in particular an upper belt and a lower belt, wherein the belts can be formed in one piece with the side wall, integrated or separate from one another.
  • the belts 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 belts therefore stiffen the support structure and form outer corner points, wherein optionally the belts and/or the Side walls serve to attach further components of the guideway device.
  • the belts can also be designed as components separate from the side wall; however, at least some of the belts are preferably formed in one piece with the side wall, for example by bending the side wall.
  • the upper belt is particularly preferably designed as a hollow profile with four walls, with two walls being formed, for example, by the L-shaped side wall 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.
  • the lower belt is also preferably designed in a similar way as a hollow profile with four walls. The components forming the walls are preferably welded together.
  • a load-bearing device comprises means for the load-resistant transfer of a force or a moment from the load to a profile, in particular a profile of the supporting structure that absorbs the force or the moment.
  • the load is a force acting on an attachment such as a balustrade or a corresponding moment that is diverted to the profile via the load-bearing device.
  • the load-bearing device is therefore intended to be attached to the element of the supporting structure (in particular the upper chord) in a load-resistant manner on the one hand and to have a load holder in which the load can be or is held in a load-resistant manner on the other.
  • Load-resistant is understood to mean that forces and moments can be transferred safely via the connection(s) at least in the directions relevant for a normal load case, in particular without material damage or failure.
  • the respective projection and the respective recess form a positive connection with each other, by which the positioning of the adapter element on the profile is determined.
  • the adapter element or the projection and/or the profile or the recess is manufactured using a high-precision manufacturing process, such as laser cutting or water cutting, so that the load-bearing device is already aligned by the positioning.
  • the first and second projections are each designed to engage in a slot-shaped recess.
  • connection to the profile is formed by the adapter element, whereby the adapter element is positioned on two sides of the profile and can then be connected to the profile on both sides, for example by welding.
  • the connection between the adapter element and the profile can also be made particularly conveniently before the receiving element is connected to the adapter element, so that, for example, welding points are particularly easy to access.
  • the solution to the problem using the load-bearing device includes the teaching that the receiving element is connected to the adapter element on both legs and in turn forms the load-bearing device.
  • the load transfer between the load-bearing device and the profile is therefore realized via both sides or both legs and the load-bearing device is therefore mechanically designed to be particularly favorable, in particular for absorbing moments.
  • the attachment points of the legs of the adapter element on the respective sides of the profile can be spaced relatively far apart from one another to absorb high moments. This advantageous design allows the adapter element and the receiving element to be made particularly small and light.
  • the adapter element can itself be designed to be particularly rigid in a plane perpendicular to the axial direction of the profile (around which a moment load mainly occurs) in order to transmit forces and/or moments in this plane, while only the receiving element also has a greater extension in the axial direction in order to form the load support for a load extending in the axial direction, such as a balustrade of a guideway device.
  • the adapter element can then be designed to be particularly compact and light.
  • the adapter element is L-shaped and made of a flat material and extends in a plane perpendicular to the axial direction of the profile.
  • the adapter element is made of a metal sheet.
  • the adapter element is then particularly light and at the same time particularly load-resistant in the plane perpendicular to the axial direction of the profile, in which the greatest forces/moments are to be expected as a load, for example in the case of a balustrade of a guideway device.
  • the L-shaped design in which the first leg and the second leg are materially connected, further increases the ability of the adapter element to transmit forces or moments.
  • first connection point and/or the second connection point are each formed by a first through-opening on the adapter element, a second through-opening on the receiving element and a fastening means that passes through the first through-opening and the second through-opening.
  • the fastening means is in particular a screw that interacts with a nut.
  • a frictional connection is then created between the receiving element and the adapter element, which is designed to be particularly load-resistant, in particular for the transmission of forces and moments in the plane perpendicular to the axial direction of the profile.
  • the alignment of the through-openings with one another ensured by the fastening means, enables highly precise positioning of the receiving element with respect to the adapter element, so that the load absorption through the aligned through-openings and the above-described highly precise positioning of the adapter element on the profile is aligned particularly precisely with respect to the profile by the recesses and projections.
  • the receiving element can be attached to the adapter element equally from a first side or a second side, so that for the mirror-inverted arrangement of load-bearing devices on two opposite upper chords, identical parts can advantageously be used.
  • the receiving element can encompass the adapter element, wherein the receiving element is mirror-symmetrical with respect to the plane formed by the adapter element, so that for the mirror-inverted arrangement of For load-bearing devices on two opposite upper chords, identical parts can advantageously be used.
  • a first through-opening is preferably designed as an arcuate elongated hole, in particular, the elongated hole extending along a radius around a rotation axis of a second first through-opening.
  • an extension along the radius is understood to mean that the radius lies on a central axis of the elongated hole.
  • an extension along the radius is understood to mean, for example, that the central axis of the elongated hole lies tangentially to the radius.
  • the receiving element can advantageously be rotated in an angular range determined by the elongated hole around the rotation axis of the second first through-opening before the fastening means are tightened or otherwise closed in order to precisely align the load-bearing element, for example relative to other load-bearing elements of other load-bearing devices provided on the same profile.
  • the load-bearing device is designed as a U-shaped clamping device, in particular for holding a balustrade panel of a guideway device.
  • the clamping device is then open in particular at the top and carries a balustrade panel such as a glass panel downwards against gravity and inwards and outwards when the balustrade is subjected to a moment load, for example by a person leaning against the balustrade or falling against it.
  • the balustrade is therefore held securely in all relevant directions and can also be easily mounted in the load-bearing device from above.
  • a sealing element and/or a shape compensation element such as a rubber profile or a paper seal can also be inserted into the U-shaped clamping device.
  • the clamping device particularly preferably has a movable clamping element, wherein a load received in the load holder can be clamped by moving the clamping element.
  • the load in particular a balustrade panel
  • the clamping element can then be inserted into the clamping device from the open side of the clamping device, in particular from above, without any great resistance. and then secured by the clamping element, in particular after aligning the receiving element relative to receiving elements of other load-bearing devices in which the balustrade panel or other balustrade panels of the same balustrade are inserted.
  • the clamping element is designed to be movable against the receiving element by means of a screw.
  • the clamping device can then be closed particularly easily by tightening the screw and the assembly of the load-bearing device is therefore particularly simple.
  • the screw is particularly preferably designed as a hammer head screw, wherein the screw passes through the receiving element so that a hammer head of the screw is held on a side of the receiving element facing the adapter element.
  • the screw is thus held on the adapter element even when the clamping device is open, i.e. without the clamping element pressing on a load and thus causing the screw to self-lock, and can therefore be pre-assembled before the load-bearing device is assembled.
  • the screw does not first have to be arranged on the load-bearing device, but only tightened. The assembly of the load is thus further simplified.
  • the screw particularly preferably acts on a pivoting element, the pivoting element being able to be pivoted about a contact point on the receiving element by means of the screw in order to move the clamping element.
  • the pivoting element therefore rests on the one hand on the contact point on the receiving element and on the other hand on a contact point on the clamping element in order to be pivoted about the contact point on the receiving element when the screw is tightened and to act on the clamping element.
  • the screw can then be locked on the receiving element away from the load bearing element so that mechanical weakening of the receiving element is prevented by providing a hole in the area of the load bearing element.
  • a lever arm between the contact point on the receiving element and the contact point on the clamping element can generate a particularly high and precisely controlled clamping force through the clamping element.
  • the object is further achieved by an adapter element for a load-bearing device described above.
  • the adapter element can be used to achieve the advantages described above with regard to the load-bearing device in a corresponding manner.
