Definitions

  • the invention relates to an elastic, wedge-shaped, insulating underlay for rails of railways laid on Y-steel sleepers, consisting of I-steel girders.
  • the special threshold type "Y-threshold” is known from LU-PS 81 116.
  • An insulating and damping, wedge-shaped underlay made of plastic is arranged between the rail and the steel sleeper; the rail guide plates are separately insulated.
  • the invention is therefore based on the object of proposing suitable shapes, materials and means for fixing the shim on the Y-steel sleepers for an improved, elastic, wedge-shaped, insulating shim.
  • the one-piece shim isolates both the rail and the clamping device and also serves as a vibration damper against the Y-steel sleeper. This eliminates a large number of individual insulating and damping parts.
  • the cross member extends to the edge of the upper flanges of the I-steel girder, so that the protrusion projecting downwards can reach over the edge of the steel sleeper. This ensures lateral fixation of the support part in the direction of the rail. This takes place when using only one transverse part to one side and only one projection initially in only one direction, but the washer part according to the invention can be used so that the lower projection engages in the gap between two adjacent I-steel girders, so that thereby fixing is given in both directions.
  • the projections of two shims according to the invention can also engage in this gap.
  • This arrangement also has the advantage that a fixation with little material for the shim is possible even if its wedge-shaped section extends only over the central part of the support surface of the I-steel girder, as is often the case and desired.
  • the projections can also be designed in the form of barbs which encompass the edge of the I-steel girder.
  • the transverse part or the transverse parts can be located at the ends of the shim lying in the wedge direction, in such a way that an I-shape is formed with the wedge-shaped section.
  • the cross parts extend to both lateral edges of the I-steel girder and thus form a lateral contact in two directions.
  • a further development of the invention is particularly expedient, in which the supporting parts of a fastening point form a single part on a Y-steel sleeper, which is formed from two I-steel girders. This keeps them at a precise distance from each other and, in addition, only a projection on the underside is required, which engages in the gap between the adjacent I-steel girders.
  • the cross parts are therefore outside the rail foot, and these cross parts can even form contact surfaces for clamping means, in particular guide plates and clamping clamps.
  • the cross members can be located in the wedge-shaped section of the two interconnected underlay members such that a transverse I-shape is formed. Both, one-piece wedge-shaped sections are connected to each other by a cross member that forms a web. The projection for lateral fixation can then be located on this in the middle at the bottom.
  • An expedient embodiment of the invention consists in that the transverse parts are arranged at the ends of the shim parts lying in the wedge direction, in such a way that the shape of a rectangular ring is formed.
  • the cross parts therefore preferably form connecting and spacing parts outside the rail foot.
  • the holes for sleeper screws can also be located in these. If they are thicker at the top than the washers, they are able to form lateral contact surfaces for the foot of a rail. In this way it is possible to shoot everyone to combine parts holding the foot of the foot into one piece, which is made of plastic and thus supports and guides the rail foot in the desired manner in an elastic or damping and insulating manner.
  • the shim has an overall insulating function, a differentiated elasticity of individual sections of the shim is advantageous.
  • the rail underlay requires different, - vibration-damping properties, while the adjacent area of the underlay part only has to absorb vibrations in the sense of a steel spring washer to prevent loosening of the screw connection with simultaneous electrical insulation the rail fastening across the steel sleeper.
  • the projections encompassing the steel sleeper should be made of very tough, dimensionally stable material that is stable at the rail temperatures of -35 ° C to + 80 ° C in European climates.
  • these projections can be laminated from glass fibers or, for example, can be made from molded steel parts cast in polyethylene.
  • a layer structure made of glass fiber or carbon fiber laminates is conceivable, which combine a long service life with high strength.
  • Polyethylene has the advantage of being resistant to water swelling and many other environmental influences during its lifetime, but it can age due to UV light, which can be caused by the addition of e.g. of 2% soot should be prevented.
  • the use of LDPE seems to be most suitable here.
  • As a sintered material it has no residual / shrinkage stresses and is e.g. can be adhesively bonded to other plastics such as epoxy resin laminates or HDPE using polyethylene copolymers with an acrylic resin additive.
  • Fig. 1 shows a section of a railroad track with two rails 1 and 2, which are attached to Y-steel sleepers 3, which consist of I-steel beams 4, 5, 6 and 7, which are connected in the manner shown at a distance from one another and so each form supports for rails 1 and 2, each of which is connected to the Y steel sleepers at the support points.
  • a fastening point in section 11 is shown in FIGS. 2 to 4 in different views and sections, which are described together below.
  • Fig. 2 is an enlarged plan view in section 11 for the rail 1.
  • the I steel beams 4 and 5 are spaced apart by bolts 8 and 9 on flanges 18 and connectors 10 and 11 under flanges 31, 32 (Fig. 3). Due to the distance, a slot 12 is formed at the top, the width of which is slightly larger than the diameter of sleeper screws 13 and 14.
  • the rail 1 rests with the rail base 15 on a wedge-shaped section 16 of the washer made of LDPE plastic, which has an inclined bearing surface 17 and which rests on an upper flange 18 of the I-steel beam 4.
  • the bolt 8 has an oblique edge 19, between which and the rail base 15 is a guide plate 20 made of insulating material.
  • a guide plate 22 lies between an oblique edge 21 of the bolt 9 and the rail foot 15.
  • Tensioning clamps 23 and 24 are each pulled through the heads of the sleeper screws 13 and 14 against the rail foot 15 of the rail 1 while they are on the other side support the threshold screws 13 and 14 on the guide plates 20 and 22, respectively, so that the rail foot 15 is resiliently pulled against the flange 18.
  • a cross member 26 is inserted from the outside into a free space 25 between the elements 4 and 5.
  • the traverse 26 consists of two pipe sections 27 and 28 which are connected to one another by means of webs 29 and 30 made of flat iron by welding.
  • the web 30 extends over the entire underside of the tube pieces 27 and 28 and also engages in a leading manner in a slot 33 formed between two lower flanges 31 and 32, so that the crossmember is guided against lateral movements.
  • the underside of the tube pieces 27 and 28 is closed by floor plates 34 and 35, which are welded to both the tube pieces and the web 30.
  • screw anchors 36 and 37 made of plastic, which are firmly embedded in the interior of the pipe pieces 27 and 28 by a binding agent 38 and 39.
  • the screw anchors 36 and 37 also have external threads 40 and 41.
  • the binding in the area of the external thread can also be designed such that the screw anchors 36 and 37 can be screwed in and out themselves.
  • the threshold screws 13 and 14 are screwed with their screw threads 42 and 43 into the screw anchors 36 and 37.
  • the screw anchors 36 and 37 are somewhat inclined to the vertical axis of the rail 1, so that they Tilt angle of the rail base flanges are adjusted.
  • FIGS. 2-4 show in different views and on a slightly different scale a washer used in a fastening point according to FIGS. 2-4 with the inclined bearing surface 17.
  • transverse parts 44 and 45 At the ends of the washer lying in the wedge direction there are transverse parts 44 and 45, of whose underside 46 protrudes 47 and 48, which form inner contact edges 49 and 50, which lie laterally on the upper flanges 18 of the I-steel beams 4 and 5 (Fig. 2, 4).
  • the cross members 44 and 45 also have rounded contact surfaces 51 and 52 for the guide plates 20 and 22.
  • FIGS. 11-13 corresponds essentially to the embodiment in FIGS. 8-10, the same functional parts are provided with the same reference numerals.
  • the transverse parts 55 and 56 protrude upward and thus form lateral contact surfaces 61 and 62 for the rail foot 15, so that the guide plates 20 and 22 (FIG. 3) are omitted.
  • 14 to 16 essentially corresponds to that in FIGS. 8 to 10, corresponding functional parts are provided with the same reference numbers.
  • the cross members 55 and 56 do not project upwards here and can even lie lower.
  • the projections 59 and 60 are designed as barbs which grip around the edges of the flanges.
  • the cross members 55 and 56 are provided with outer cutouts 63 and 64 to save material.
  • 17 -19 illustrate in principle the use of a shim, similar to FIGS. 8 -10, 11 -13 or 14 -16.
  • Two wedge-shaped sections 65 and 66 of the shim are located in the region of the central axis of the two I-steel beams 4 and 5 according to FIG. 2, are connected by transverse parts 67 and 68 outside the rail foot 15 shown in FIG. 18 and have holes 57 and 58 for sleeper screws.
  • the projections 71 and 72 engage in the gap 12 between the two I-steel girders 4 and 5, and the entire washer is thus fixed in the direction of the rail (FIG. 19).
  • 20-22 show another embodiment in principle, similar to FIGS. 17-19. Corresponding functional parts are provided with the same reference numbers. Instead of the transverse parts 67 and 68, only one transverse part 74 is provided as a central connection between the wedge-shaped sections 76 and 77, on which there is a lower projection 75, which in turn engages in the gap 12.
  • FIGS. 23-25 A further embodiment of a shim according to the invention and its installation situation are shown in FIGS. 23-25.
  • a shim with surface 17 (inclination 1:40) consists of a 4-11 mm thick, wedge-shaped base 73 made of glass fiber epoxy resin pressed laminate with integrally formed cross parts 45 and 45 and projections 47 and 48 for gripping around the threshold edges and lips 78 for electrical insulation (Fig. 23).
  • Throats 51 and 52 for receiving the steel guide plates 20 and 22 (FIG. 25) are embossed in the transverse parts 44 and 45.
  • a 7 mm thick cushion 75 made of polyurethane (thrust module approx. 4 x 10 6 Pa) is firmly connected with epoxy adhesive 74.
  • the overall rigidity of the wedge-shaped section of the washer corresponds approximately to a shear modulus of 8 x 10 7 Pa.
  • Fig. 25 shows the shim in use when attaching a rail 1 to an I-steel beam 4, similar to Fig. 3.
