Definitions

  • the present invention relates to a structure for a passenger transport system such as an escalator, a moving walk etc.
  • Passenger transport facilities are used to transport people, for example, in buildings between different height levels or within a constant height level.
  • escalators which are sometimes referred to as escalators, used to transport people, for example, in a building from one floor to another floor.
  • Moving walkways can be used to convey people, for example, within a floor in a horizontal plane or only a slightly inclined plane.
  • Escalators and moving walks generally have a load-bearing structure called a supporting structure.
  • the structure is designed to absorb forces acting on the passenger transport system during the transport of persons, in particular weight forces, and to forward them, for example, to supporting structures of the building receiving the passenger transport installation.
  • suitable bearing points can be provided on the building.
  • the structure may extend over two or more levels or floors of the structure and / or over shorter or longer distances within a constant floor within the building.
  • a supported in the mounted state at the bearing points of the building structure can accommodate both movable and stationary arranged components of the passenger transport system.
  • such components may be formed, for example, as a stepped belt, pallet belt, deflection axles, drive shafts, drive motor, transmission, control, monitoring system, security system, balustrades, comb plates, bearings, raceway and / or guide rails.
  • structures for passenger transport systems are designed as truss structures.
  • Such truss structures are traditionally already at the manufacturer manufactured as a whole unit or divided into several structural modules.
  • the structure, which is pre-assembled as a complete unit or subdivided into several modules, is then transported to and assembled in the building in which the passenger transport system is to be installed.
  • a truss forming the framework is generally composed of a plurality of rod-shaped truss components. In order to ensure sufficient stability and load carrying capacity of the structure, the individual truss components must be connected by connections of sufficiently high strength. Traditionally, trusses for structures or structural modules are usually made by conventionally welding together a plurality of sectional steel elements of different cross-sectional area and cross-sectional shape.
  • a structure for a passenger transport system which can be assembled easily, inexpensively and / or with high precision.
  • a structure for a passenger transportation system which can be assembled on site within a structure near a position where the passenger transportation system is to be installed.
  • a structure for a passenger transport system has a framework of interconnected load-bearing truss components.
  • truss components may include, for example, so-called upper straps and lower straps and these straps interconnecting transverse struts, diagonal braces and / or posts.
  • With uprights timbered components are referred to connect a top chord with a bottom chord, specify the parallel distance of top chord and bottom chord and usually extend to the shortest possible distance between the two. Since their longitudinal extent is thus arranged mostly orthogonal to the upper and lower chords, they are particularly suitable that connection points for other components of the escalator or the moving walk are arranged on the uprights.
  • connecting openings are formed.
  • the truss components are interconnected by means of load-bearing connector components passing through connection openings of at least two adjacent truss components.
  • the connector components are designed and mounted in such a way that they fill the connecting openings through which they pass through completely and without play, thereby positioning them relative to one another.
  • framework structures for structures of a passenger transport system have been produced mostly by welding suitably designed truss components. Welding a variety of truss components together requires a lot of time and effort. Since the structure is a safety-relevant component, welded seams used in this case may normally only be executed by well-trained, state-certified experts. Furthermore, in general, large gauges are required for the manufacture of such welded constructions, and the effect of heat during welding usually requires straightening of the finished component. Furthermore, for a transport prefabricated at a manufacturer entire structure or individual structural modules towards a building and into the building in, in which the passenger transport system is to be installed, a considerable effort and therefore considerable costs.
  • truss component-forming bars are connected together using screw-on nodes. This should be possible to produce as distortion-free framework.
  • the disclosed truss must be laboriously constructed using gauges because the individual fasteners in a plane have too many degrees of freedom due to the existing play.
  • the fasteners pose a security risk, since the screws used in this case can be solved by clamping elements.
  • the connection of the individual truss components is at least only one force fit, at least with respect to one degree of freedom, so that, for example, could be forgiven by lateral force the entire framework.
  • a framework-forming load-bearing framework components similar to the last-mentioned prior art, are connected to each other without welds or at least without a major portion of the load acting on the framework load.
  • a special type of mechanical connection of two or more truss components is to be used with each other.
  • the special nature and properties of these compounds results mainly from the connector components used for this purpose.
  • these connector components should have sufficient mechanical stability so that they can absorb the forces and loads acting on the framework at least to a predominant extent, that is to say the connector components should be designed to bear load.
  • the connector components are designed to be load-bearing in such a way that they can preferably withstand at least the same loads as the truss components connected by them.
  • the connector components should be designed and mounted in such a way that, during the connection of two or multiple truss components positioning them in a predeterminable manner relative to each other.
  • connection openings can be formed as passage openings or holes in the respective truss component.
  • the connection openings are rotationally symmetrical, in particular with a round or circular cross-section.
  • a cross-sectional area of the connection openings may be, for example, between 0.1 cm 2 and 20 cm 2 , which corresponds to a diameter of approximately between 4 mm and 50 mm in the case of circular connection openings.
  • all provided in the various truss components connection openings are designed the same, in particular with the same cross-sectional area and the same contour.
  • a truss component are generally at least two connection openings, for example, near opposite ends of the truss component is formed.
  • the individual truss components can be interconnected by means of the already mentioned load-bearing and positioning-acting connector components.
  • the connector components used for this purpose are specifically designed so that they complete after assembly, that is, in a state connecting at least two half-timbered components, fill the connecting openings of the truss components to be connected by them completely and without play.
  • connection openings Under a complete and play-free filling of the connection openings can be understood that outer surfaces of the connector components during assembly so on surfaces of the truss components, especially on surfaces that form an inner boundary of the connection openings, create or nestle that the connector components to the truss components and in particular are kept free of play in their connection openings in all spatial directions.
  • the interconnected truss components can preferably move in any direction relative to each other due to a caused by the connector component positive locking, but at least less than 0.3mm, preferably less than 0.1mm or more preferably less than 0.03mm can move relative to each other.
  • the connector components should be configured and mounted so that they connect the truss components to be connected by a positive connection in all directions.
  • the positive connection should also act in directions within a plane formed by the truss components, that is to say in directions perpendicular to a longitudinal extension direction of an elongate connector component.
  • the connector components to be used for the structure proposed herein differ from simple connector components conventionally used for trusses, such as glands or classic rivets.
  • Such screw connections or conventional riveting usually only bring about a positive connection along a longitudinal direction of the connector component, whereas the interconnected truss components are only positively connected in directions transverse to this longitudinal direction.

  • the connector components should preferably be designed such that they have a lateral surface which is dimensioned such that they pass through adjacent to each other arranged connecting openings of two adjacent truss components easily, that is, with a certain play, can be inserted therethrough. Subsequently, the connector components are to be deformed during further mounting such that the cross-engaging through the connecting openings lateral surface is radially expanded.

  • the lateral surface is to be so greatly expanded during the assembly process that it even exerts a certain pressure outwards on inner edges of the connection openings in the radial direction. This pressure may for example result from a permanent elastic deformation of the lateral surface and / or the edges of the connection openings.
  • the fully assembled connector component should be press-fitted into the associated connection opening.

It is also stated that when assembling such a blind rivet bolt, a sleeve-like shaft, which was previously introduced into connection openings of two components to be connected, is first radially expanded by a so-called shoulder, which has a slightly wider cross section than an inner cross section of the shaft, through the Shaft is pulled through and plastically deformed outwardly, so that the lateral surface of the shaft fits snugly against the inner surfaces of the connection openings. Only then are appropriately formed rivet heads formed by suitable plastic deformation of end regions of the shank so that the components to be connected are fixed in a form-fitting manner to one another in all spatial directions by the assembled blind rivet bolt.

  • connection openings are arranged to each other with a tolerance of less than 0.3 mm, preferably less than 0.1 mm and more preferably less than 0.03 mm, in the truss components.
  • connection openings in the truss components are spatially very precisely formed and arranged.
  • the "tolerance” is intended to refer to both the position at which a connection opening is arranged in a truss component, as well as their dimensions and contours.

  • the angle brackets 25 at the transition points between the central region 17 and the upper or lower end region 19, 21 of the truss 3 essentially determine an angle of inclination of the finally installed escalator.
  • the uprights 15 may have a flange with two mutually perpendicular surfaces, which may be connected in an assembled state with two surfaces of square tubes of the upper and lower chords 7, 9. Reinforcement angles can also be provided on the square tubes.
  • end portions 19, 21 or entrance areas, or deflection heads of the passenger transport system may for example be cast from fiber reinforced cement.
  • Such cast end portions 19, 21 may comprise roadways made of the cementitious material for the rollers of a step belt or pallet belt as well as receiving points of bearings and drive parts.
  • the cement-molded end regions 19, 21 must also have connection points, so that a central region 17 constructed by means of connector components 27, top straps 7, bottom straps 9, uprights 15, cross struts 11 and diagonal struts 13 is inserted between the two cast end regions 19, 21 can.
  • connection openings 39 suitably formed therein.
  • a plurality of structurally identical uprights 15, cross struts 11 and / or diagonal struts 13 can be produced in series in advance and equipped with connection openings 39 tuned to bore-filling connector components.
  • two sheet metal parts to be assembled together can be provisionally connected to each other in advance, for example, by being connected by means of plug connections which are secured locally inseparably by welds or crimp-like deformations.
  • the uprights 15 have connecting openings 39 arranged at both ends, which can be arranged precisely with respect to one another and a parallel spacing of upper belt 7 and lower belt 9. At least one of the sheet metal parts of a stanchion 15 may have receptacles for fastening rails, wherein the receptacles 27 are formed precisely arranged relative to the connection openings 39 for the connector components 27.
  • the connecting openings 39 to be formed in the transverse or diagonal struts 11, 13 are also arranged precisely spaced from each other at opposite ends of these struts.
  • connection openings 39 must be precisely calculated with respect to an ultimately achieved individual truss geometry and formed in the upper and lower chords. In this case, a height of the uprights 15 and a distance of connection openings 39 in the diagonal struts 13 is to be considered.
  • H-frames 69 To assemble the truss 3 of the structure 1, it may be advantageous to first preassemble a plurality of H-frames 69 by connecting each of two uprights 15 to at least one transverse strut 11 using the bore-filling connector components 27 described herein.
  • Such H-frames 69 can easily be handled by a single person.
  • the H-frames 69 can then be precisely connected by means of the connector components 27 with the upper straps 7 and the lower straps 9.
  • the diagonal struts 13 can be inserted and in turn connected by means of connector components 27 with the already prefabricated remainder of the truss structure.
  • At least one of the sheet-metal parts may hereby have receptacles for fastening rails and for their fastening by means of connector components 27 precisely aligned connecting openings 39.
  • a particular advantage of the structure 1 described herein can be seen in the fact that it can be used by means of an assembly method using the special properties of this structure particularly simple for the assembly of passenger transport equipment in existing structures. For example, it may sometimes be necessary to replace existing passenger transport systems in a building or to retrofit a building in addition to passenger transport systems.
  • Truss components 5 are introduced with the already pre-trained connection openings 39 to a mounting position within the building. If it is an exchange of a passenger transport system, the existing passenger transport system may be removed in advance if necessary. Furthermore, at least two support points for receiving the passenger transport system can be prepared in the building. If necessary, a temporary framework can also be created between such supports.
  • the disassembled truss 3 can be assembled with its truss components 5 then directly within the building.
  • the individual half-timbered components 5, which are in part provided as standard components of identical construction, can be connected to one another as described using the load-bearing and position-giving connector components 27 and thus form the high-precision truss 3.
  • the truss 3 thus assembled can finally be mounted on the prepared mounting points of the structure within the building.
  • the framework for the proposed structure 1 can be much more cost-effective to build than an example continuously welded framework.
  • it can be assembled on site without mounting lays in an extremely short time, for example within a few hours or less days.
  • the only tool in this case for example, a correspondingly suitable for the assembly of the connector components 39 rivet gun is required.
  • a correspondingly suitable for the assembly of the connector components 39 rivet gun is required.
  • For an assembly of the truss 3 advantageously no certified professionals such as certified welders are required.
  • a subsequent straightening of the framework can usually be omitted.
  • Components of the truss, in particular its truss components 5, can be painted or, in particular, galvanized prior to their assembly.
  • a transport volume of the initially dismantled truss 3 can be extremely small.
  • the individual truss components 5, for example, can be easily introduced through existing openings in an interior of a building be without, for example, walls of the building would have to be broken. Even dirt and noise emissions at the installation site can be minimized by the use of clean and precise connection technology using the special connector components 27, for example, cleaning, cutting and grinding and welding work on, for example empty salvaged trusses, as otherwise often incurred in modernization solutions, not necessary are. Furthermore, it can be seen as an advantage that, due to the possibility of being able to build the truss 3 at the installation location, a high local production proportion can be achieved. This can be a crucial selling factor, especially for public sector contracts.
