Definitions

  • the invention relates to a device of the type mentioned in the preamble of claim 1 for fastening rails on Y-steel sleepers.
  • a device of this type is known from the Luxembourg patent specification 81 085, in which the traverse can be made of steel with two tubular parts with screw holes and a web connecting these parts or a steel fiber concrete block into which screw dowels for the sleeper screws are cast at a suitable distance from one another.
  • Such crossbeams are each laterally inserted at a fastening point between the rail and a Y-steel sleeper into a cavity which is formed between two steel support parts which are H-shaped in cross section and are connected at a distance from one another in the region of a fastening point.
  • the upper legs with their mutually facing edges form a slot between them, which forms an opening for the sleeper screws.
  • the crossbeam When fastened, the crossbeam lies from the inside on the upper inner legs of the two H-beam parts.
  • a cross member designed as a steel fiber concrete part or welded steel part is relatively expensive and complex to manufacture. If the concrete part cracks or breaks, the screw anchors can loosen. Such cracks and breaks result from changing loads and weather influences.
  • the steel crossbar is very rigid. When tightening or loosening the steel spring that clamps the rail foot, bending and torsional forces act on the sleeper screws. These destroy the screw and / or the screw anchors. With both types, parts have to be replaced after some time.
  • the invention has for its object to improve a device of the type mentioned above for fastening rails on Y-steel sleepers with regard to their durability, reliability and manufacturing costs and to achieve that during the long life of sleepers and rails, the sleeper screws in the crossmember several times can be loosened, tightened and tightened without causing damage.
  • the design of the traverse made of plastic means a considerable cost saving compared to the traverse made of steel fiber reinforced concrete or steel, while at the same time increasing durability and reliability.
  • the screw anchors or the screws can be easily screwed into the bores of the tubular parts, and when screw-in screw anchors are screwed in, a pressure is also applied, so that an increase in the frictional engagement is achieved.
  • the two screw holes are inclined towards one another in the screwing direction.
  • the traverse can consist of a single piece made of injection molded or cast plastic.
  • tubular parts of the crossmember have a widened cross section in the region of their contact surface against the sleepers in order to enlarge these contact surfaces.
  • tubular parts may be provided with internal or external reinforcement, for example in the form of rings, pipe sections, fabric or the like.
  • Fig. 1 partially shows one
  • FIG. 2 is an enlarged top view in section 11 for the rail 2.
  • FIG. 3 is a section 111-111 through FIG. 2
  • FIG. 4 is a section IV-IV through FIG. 2.
  • the elements 4 and 5 made of H-steel profiles are connected by bolts 8 and 9 on the top and bolts 10 and 11 on the bottom at a distance by welding.
  • a slot 12 is formed by the distance, the width of which is slightly larger than the diameter of sleeper screws 13 and 14.
  • the rail 1 rests with its foot 15 on a base plate 16 made of plastic, which in turn rests on a slightly wedge-shaped base plate 17 which rests on an upper cross part 18 of the element 5.
  • the bolt 8 has an inclined edge 19, between which and the foot 15 a guide plate 20 is located in a corresponding manner between one inclined edge 21 of the bolt 9 and the foot 15 a guide plate 22.
  • Tension clamps 23 and 24 are each drawn through the heads of the sleeper screws 13 and 14 against the foot 15 of the rail 1 while they are on the other side of the sleeper screws 13 and 14 respectively Support on the guide plates 20 and 22 so that the foot 15 is resiliently pulled against the cross member 18.
  • a cross member 26 is inserted from the outside into a free space 25 between the elements 4 and 5.
  • the cross member 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 pipe sections 27 and 28 and also engages in a leading manner in a slot 33 formed between two lower transverse parts 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 which are embedded in the interior of the pipe sections 27 and 28 by a binding agent 38 and 39.
  • the screw anchors 36 and 37 also have external threads 40 and 41. If necessary, the binding in the area of the external thread can also be designed in such a way that the screw anchors 36 and 37 can themselves be screwed in and out.
  • the threshold screws 13 and 14 are screwed into the screw bolts 36 and 37 with their screw threads 42 and 43, respectively.
  • the bolts 36 and 37 are slightly inclined in the direction of the elements 4 and 5, so that they are adapted to the angle of inclination of the lower rail flanges.
  • FIG. 5 shows, according to the invention, a crossmember 52 which has two tubular parts 53 and 54 in which bores 56 are provided centrally, optionally with an internal thread 55, for screwing in the screw threads 42, 43 of sleeper screws 13, 14 (FIGS. 2-4) are and which together with a web 57 form a piece that is cast or injection molded from plastic.
  • the tubular parts 53 and 54 have a larger cross section, so that flange-shaped thickenings 60 and 61 are formed, which serve to enlarge the contact surfaces 58 and 59 and also to reinforce them.
  • ring-shaped reinforcements 62 in the area of the thickenings 60 and 61, which are made of steel, glass fiber or the like and can also have other shapes familiar to the person skilled in the art.
