Definitions

  • the invention relates to an arrangement for connecting a structure, in particular a bridge structure, with a foundation or mainland, with rails fixed on the structure and rails extending on the foundation or mainland using a dilatation device for absorbing movements in the longitudinal direction of the rail, in which between the structure and the foundation or mainland, a carrier which is displaceable in the longitudinal direction of the rail is arranged, which is coupled to the structure in the direction of displacement, and in which the dilatation device is connected to the side of the displaceable carrier facing away from the structure.
  • AT-PS 337 747 has already proposed a device for absorbing longitudinal rail extensions, in which a rail joint is divided into a plurality of jointed surfaces to bridge larger dilatation paths without causing excessive dilation joints.
  • a rail joint is divided into a plurality of jointed surfaces to bridge larger dilatation paths without causing excessive dilation joints.
  • training has become known in which wheel links are required in the region of the gap.
  • the rail parts which are movable relative to one another are offset in the longitudinal direction to half the cross section, so that they result in the full rail cross section in the overlapping regions.
  • US Pat. No. 4,785,994 already shows a dilatation device in which a control rail with a relatively large radius is deflected and is slidably supported on the outside of a tongue rail. At a Such training does not result in any lane changes in the area of the dilation device and a relatively large displacement path can be implemented with a single dilation device.
  • the invention now aims to provide an arrangement of the type mentioned at the outset, with which the displacement forces are introduced exactly and only in the longitudinal direction of the rail in any dilation devices, in particular in dilation devices with a relatively large permissible displacement path, in a single device those areas in which they are slidably attached to base plates or sleepers, can be held securely in place with low sliding resistance. Furthermore, the design according to the invention aims to ensure that, in the area of the transition between the supporting structure and the foundation, even under extreme loads, no forces that could jeopardize the secure fixing and anchoring of the rails occur, and such eccentric forces that do not act in the longitudinal direction of the rails, without overstressing the bearing components of sliding parts to be able to record.
  • the arrangement according to the invention essentially consists in the fact that the supporting structure is non-positively connected, in particular welded or screwed, to the displaceable carrier with the interposition of a flexible connecting link.
  • a flexurally elastic connecting piece or link allows, in contrast to known constructions in which the connection is made in the manner of a stretch of line with clearly pronounced kinks, to absorb bending forces in such a way that an inadmissibly small radius of curvature does not occur at any point .
  • Such an impermissibly small radius of curvature, for example at the transition points, would result in high forces acting in the direction of pulling out anchoring elements or parts for fixing rails, and the use of the flexible intermediate link here permits the forces that are theoretically conceivable in this direction to be significantly reduced by uniform distribution over the length of the flexible intermediate member.
  • the stress on the bearings of the longitudinally slidable beam and the bearing structure or the bridge bearing is naturally significantly reduced.
  • the flexurally elastic connecting member is designed as a torsion bar, with advantageous support for the safe support of high loads How the flexurally elastic connecting element cooperates with elastic, in particular resilient, abutments.
  • a torsion bar can be designed, for example, as a rectangular profile bar, the preferred bending direction of such a rectangular profile naturally being the bend over the narrow edge of the rectangular profile. In other words, this means that the rectangular profile with its narrower side is installed in the vertical direction between the displaceable support and the supporting structure and can be butt-welded at the ends to these ends.
  • the design is advantageously made such that the flexible connection member engages over the displaceable support and the supporting structure in the areas of the non-positive connection with these.
  • the welding or screw connection ensures that the loads are absorbed in the exposed area of the flexurally elastic connecting member.
  • the elastic abutments already mentioned at the outset which are intended to additionally support the bending forces, are developed in a particularly advantageous manner in such a way that the elastic abutments arranged below the flexible connection element are arranged in a carrier which is attached to the Supporting structure and is slidably supported on the movable support.
  • the theoretically conceivable displacement path in the respective sliding support is naturally limited by the non-positive connection of the flexurally elastic connecting member with the two parts mentioned.
  • the interposition of a flexurally elastic connecting member with such a configuration of the device according to the invention, the possibility is created to ensure that only axially following the flexurally elastic connecting member and in particular following the displaceable in the longitudinal direction of the rail Forces are introduced into the rails.
  • the rigidly fixed rails on the sliding support in their sliding bearings in the longitudinal direction of the rails in which they are guided in the longitudinal direction on the foundation or on sleepers or on such sleepers supported on a foundation.
  • the design of the sliding plates can be dimensioned so that they only reliably absorb displacement forces in the longitudinal direction, while at the same time the displacement resistance in the longitudinal direction can be kept considerably lower, since eccentric loads must not be expected.
  • the design is such that the displaceable support has on its side facing away from the supporting structure at least one recess running in the longitudinal direction of the rail, into which a part of the foundation or a rigid support on the mainland side is immersed, the rails on the displaceable support being rigid and Slidable on the foundation up to the dilator in the longitudinal direction of the rail are stored, such a design already allowing the movable carrier to be guided in a precisely defined direction, namely in the longitudinal direction of the rail.
  • FIG. 1 shows a plan view of an arrangement according to the invention for connecting rails
  • 2 shows a schematic side view of the design according to FIG. 1
  • 3, 4 and 5 on an enlarged scale, sections along the lines III-III, IV-IV and V-V, only one rail being shown in detail

  • FIG. 7 shows a perspective schematic plan view of a modified embodiment of the mounting of the flexible connection element in the arrangement for connecting Rails.
  • 1 denotes a supporting structure, in particular a bridge supporting structure, adjacent to the mainland or foundation 2.
  • a supporting structure in particular a bridge supporting structure, adjacent to the mainland or foundation 2.
  • length compensation must be carried out over partially considerable distances, for example to the extent of 3 m, it being possible to drive on even at high speeds.
  • a support 4 which can only be moved in the longitudinal direction of the rails 3, is displaceably guided on slide bearings, not shown, on the foundation or mainland 2.
  • a flexurally elastic connecting member 5 is arranged, which is non-positively connected to both the supporting structure 1 and the supporting structure 4, a screw connection being indicated by 6.
  • a weld can also be used be provided between the structure 1 and the flexible support 5 or the support 4 and the flexible connector 5.
  • the flexurally elastic connecting member 5 also interacts with elastic, in particular resilient abutments in a component 7, the abutment component 7 being supported both on the supporting structure 1 and on the displaceable support 4.
  • the storage of the flexible link 5 is shown in Figures 6 and 7 in more detail.
  • the rails 3 are each rigidly fixed on the bridge structure 1, on the flexible connecting link 5 and on the carrier 4 which can be displaced in the longitudinal direction.
  • a dilatation device 8 is arranged directly on the end of the foundation 2 facing the displaceable support 4, the rail ends 10 rigidly connected to the support 4 being deflected by a tongue device 9 and corresponding to the displacement path or the length change to be compensated over a corresponding length along the deflection device 9 are moved.
  • the deflection device has, for example, a deflection radius of 150 m, it being possible in this way to compensate even large displacement lengths with a single dilation device.
  • the displacement of the rails 3 with the carrier 4 which can be displaced in the longitudinal direction of the rail is indicated by the rail region 3 'indicated by the broken line in FIG.
  • the rail 3 is guided in sliding guides in the subarea over which a displacement of the longitudinally displaceable carrier 4 to compensate for longitudinal expansions is made, one on the foundation or that connected to the foundation 2 in the direction of the displaceable carrier 4 protruding portion 12, a slide plate 14 is provided.
  • the slide plate 14 overlaps the rail base with an extension 15, while a separate, removable slide guide 16 is provided on the side opposite the extension 15.
  • the rail 3 is both slidably supported on the foundation extension 12 and rigidly connected to the displaceable support 4.
  • the support on the foundation extension 12 takes place in a manner similar to FIG. 3, again via a sliding device 16.
  • a metal reinforcement profile 17 is provided to protect the foundation extension 12.
  • the rail 3 is connected to the displaceable carrier 4 via a connecting element 18 which is rigidly connected both to the displaceable carrier 4, as indicated by a screw connection 19, and to the rail 3 via a screw connection 20.
  • the connecting element 18 has a recess 21, into which the corresponding portion of the foundation extension 12 can be received when the displaceable carrier 4 is displaced in the direction of the arrow 22 in FIG. as it is indicated by dashed lines at 15 '.
  • a summary of FIGS. 3 and 4 thus shows that the foundation extension 12 is offset in the area that plunges into the recess 13 of the carrier 4, as indicated by 23 in FIG.
  • the fixing of the rail 3 is shown in that part of the sliding support 4 in which the side surfaces of the sliding support 4 when inserted, i.e. upon penetration of the foundation extension 12 into the recess in the displaceable carrier, come directly into contact with the side surface of the foundation extension for appropriate guidance thereof.
  • the rail is again rigidly connected to the carrier 4 in this partial area via a connecting element 18 and a conventional clamping plate attachment 29.
  • FIG. 6 shows schematically the mounting of the flexurally elastic connecting member 5 in the abutment component 7, the suspension being indicated schematically by 25.
  • the connecting member has, for example, a rectangular cross section and is designed as a torsion bar, so that all off-center loads can be absorbed and compensated by the connecting member 5 and the support 4 is only axially loaded in the longitudinal direction of the rail.
  • an additional support 26 is provided in each case in the end region of the sleepers in addition to the connecting member rigidly connected to the threshold 24 on the abutment component 25.
  • FIG. 7 shows a modified embodiment of the mounting of the flexurally elastic connecting member 5, wherein instead of the screw connection provided in FIGS. 1 and 2 between the supporting structure 1 and connecting member 5 and between the carrier 4 and the connecting member 5, a weld 27 is provided in this case is.
  • elastic abutments in the form of transverse beams 28 extending transversely to the connecting member 5 are provided, which in turn can be arranged in a component corresponding to the abutment component 7 or in adjoining partial areas of the supporting structure 1 and the support 4 can be stored.
