Definitions

  • the invention relates to a track section according to the preamble of claim 1.
  • the invention relates to a method for connecting a wing rail as a first track component, with a frog point or with a connecting rail connecting them as a second track component, with a distance between them and this spaced spacer, such as lining piece, wherein the spacer with at least one the rail track having track components in the web area is materially connected.
  • intersections of rail tracks give rise to intersections, whereby the edges of the intersecting rail tracks are interrupted in the center.
  • the rail strands continuing from the tongue rails are bent in the center piece area and called wing rails.
  • the DE 44 42 416 C2 is a lining piece for fixed spacing between two rail sections, in particular a wing rail and a frog point, refer.
  • the lining piece on the rail side has an oval plate, through which a corner clearance is given. As a result, voltage peaks are avoided by the welding.
  • the core ie after the wing rail has been welded to the core block via the lining pieces, is tempered as a unit.
  • the DE 42 24 156 A1 shall be taken from a frog whose tip consists of unwelded parts. In order to exclude a relative movement between these, the frog parts are passed through a sleeve without play, in which a bolt extends, via which the wing rails associated with the frog point are interconnected.
  • a generic track section is the DE 1 009 656 B refer to.

  • a cohesive connection is used to connect the spacer with the track or the components, but the reason of the structural state of the track components remains unaffected, since the cohesive connection should extend exclusively between the tubular element and the spacer, according to the state
  • the technology is also welded.
  • the number of connections according to the invention can correspond to the number of conventional screw connections in the case of a centerpiece.
  • any rail qualities can be used, a particular advantage of the teaching of the invention.
  • Suitable welding methods are in particular inert gas welding, preferably metal-active gas welding, preferably MAG 135/136 according to DIN EN ISO 4063: 2011-03, or arc welding, in particular manual metal arc welding 111 according to DIN EN ISO 4063: 2011-03.
  • the tubular element such as bushing, passes through the passage opening, such as bore, in the rail web, so that from the distance piece facing away from the Stegs starting the cohesive connection, such as welding, can be performed.
  • the tubular element - hereinafter also referred to as a sleeve - has on its distance piece remote from, ie remote side extending transversely to the longitudinal axis of the bushing portion such as collar, in particular circumferential collar, which bears against the outside of the web.
  • the distance piece side extending end face of the bushing extends back to the distance piece side extending web inner surface.
  • a gap forms between the bush and the spacer when it is supported on the web or presses against it.
  • a method for connecting a wing rail as the first track component, with a frog point or a weld rail merging into this second track component, with a running between them and this spaced spacer, such as lining piece, wherein the spacer with at least one of a rail web track components in its Web portion is integrally connected, is characterized in that in the rail web, a through hole is inserted, that in the through hole, a tubular element is used, which has a distance piece side extending end face, which is set back to the spanned by the distance piece side rail web outer surface plane, and that the tubular element is fixed in the passage opening by press-fitting and connected in a material-locking manner with the spacer.
  • the invention provides that the web and thus the track component is held between the spacer and a distally facing away from the side of the web extending portion, such as collar, the tubular member.
  • the invention is characterized in that from each of the web components having a web emanates a tubular element and that each tubular element is connected in a material-locking manner with a spacer which separates the track components.
  • materials for the tubular elements or bushings are preferably steels, in particular those of material group 1.2 according to CEN ISO / TR 15608: 2005, in question.
  • Fig. 1 is a plan view of a rigid core shown, comprising as essential components a frog point 9 in block construction and with this connected weld rails 6, 12. Along the frog point 9 and in regions along the weld-on rails 6, 12, it is known to extend wing rails 1, 11, which merge into tongue rails of a switch having the illustrated frog. In that regard, it is well known constructions.
  • the wing rails 1, 11 with the frog block tip 9 and the Ansch cumschienen 6, 12 and the connection of the Ansch cumschienen 6, 12 are interconnected.
  • corresponding fastenings in rigid core pieces are realized by screw connections.
  • a spacer between the rails to be connected or rail and block tip a spacer, a lining piece, positioned.
  • a screw is introduced, with which the components are clamped high-strength.
  • the screw can solve. This is where the invention starts.
  • a screwless connection is proposed, which is carried out by welding, wherein the rails are basically not welded, so that microstructural changes in these are avoided or largely avoided. This should be based on the Fig. 2 to 4 be explained in more detail.
  • both the wing rail 1 and the Ansch whoschiene 6 each have a head 21, 26, which merges via a web 23, 28 in a rail foot 25, 30.
  • Each web 23, 28 has a bore 27, 34, into which a bush 2, 5 can be inserted, each having a flange or collar 14, which in in the bore 27, 34, by press fitting inserted socket 2, 5 on the Outside 29, 36 of the web 23, 28 abuts, as the Fig. 2 and 3 clarify.

Furthermore, radial sections protrude from the base body 38 in order to support the lining piece 4 on the underside of the head 21, 26 or the upper side of the foot 25, 30.
  • a welded joint 3 is produced by gas-shielded welding, such as metal-active gas welding, or arc welding, such as manual arc welding.
  • gas-shielded welding such as metal-active gas welding
  • arc welding such as manual arc welding.
  • the collar or flange 14 of the sleeve or sleeve 2 extends, as mentioned, along the outside 29, 26 of the web 23, 28, ie opposite the weld seam 3, so that after the welding operation the rail 1, 6 is held against the lining piece 4.
  • the components are geometrically designed so that the lining piece 4 presses against the rail web 23, 28.
  • the web 23, 28 is quasi clamped between the flange or collar 14 of the socket 2, 5 and the lining piece 4, fixed.
  • Fig. 3 shows that the distance between the end face 48 of the bushing 2, in the region of the weld 3 extends, and web-side edge 50 of the collar 14 is less than the thickness of the web 23, 28, so that between the end face 40, 42 of the lining piece. 4 and the sleeve 2 or the frontally extending edge 48 results in a gap 7.
  • residual stresses in the connection which arise through the introduction of the welding heat, contribute to a frictional connection of the components.
  • a bush or sleeve is provided only in the wing rail 1, 11, whereas the lining 10 is welded to the core block 9 in the usual way.
