Definitions

  • the invention relates to a grooved rail crossing region according to the preamble of claim 1.
  • the grooved rails are milled as such in the crossing region to form a top flange and a bottom flange.
  • the upper flange and the lower flange are each made of a rail profile in the area below the grooves.
  • the US-A-178.140 describes a grooved rail crossing region of two grooved rail strands, each grooved rail strand being formed of two parallel rails. At the points where the rails intersect, the one rail has a reinforcement or protrusion on the underside. On the top of a recess is accordingly provided for another rail. The other rail in turn has on the bottom and the longitudinal sides shoulders, so that it is possible to put the other rail from above into the recess in the one rail, so that the grooves are aligned.
  • crossing grooved rail strands usually consisting of a block connecting elements are provided, which have on the sides connecting portions for connecting the two ends of the crossing grooved rail strands to the connecting element.
  • the connecting element has a first driving groove with a crossing region of a second driving groove and a crossing second driving groove.
  • the known connection elements consist of pre-tempered steels, which exceed the dynamic properties of the rail material and have a high strength in the tempered state.
  • the total four ends of the two grooved rail strands are usually welded to the terminal regions of the connecting element in the region of the grooves.
  • Object of the present invention is to provide a grooved rail crossing area of the type mentioned is available, which is inexpensive and easy to straighten and has a high strength in the field of grooves.
  • the top chord and / or the bottom chord can be adapted to the respective conditions almost as desired in length, the connection areas provided at the ends of the top chord and the bottom chord for connection to the intersecting grooved rail strands being far from the immediate intersection region - and thus out the highest stress area of the core - can be laid out. This is particularly advantageous when the grooved rail strands are welded to the heart, since welding processes then exert no damaging effect on the material structure and thus on the remuneration in the immediate crossing region of the heart.
  • the grooved rail crossing region according to the invention can in principle be provided without any problems in all intersections of grooved rail strands, for example also in turnout installations.
  • the crossing angle of the intersecting grooved rail strands only the crossing angle between the upper belt and the lower belt has to be determined in order to provide a largely direction-free connection of the grooved rail strands to the heart of the grooved rail intersection region.
  • a "90 ° intersection" is especially suitable.
  • the upper chord and / or the lower chord is made of a solid profile, wherein the respective recesses are reworked by a machining, so that no rolled special profiles must be used in each case.
  • results from the training as solid profile of the main advantage that a breaking of the grooves due to the dynamic stress when driving over the wheel of the rail vehicle is not possible.
  • identical strands of solid material can be used for both straps, which is inexpensive.
  • the upper flange has at least one first recess on the underside, while the lower flange has on the upper side a second recess complementary to the first recess.
  • the terms "upper flange” and “lower flange” are based on the corresponding specialist terminology of the framework technology.
  • the upper and lower chords grip in such a way that results in a play-free positive engagement in the region of the recesses.
  • the upper flange and the lower flange are in addition to the aforementioned positive engagement on the side facing away from the grooves on another connected and / or fixed.
  • further connection ensures that when driving over the heart through the wheel of a train can not come to a lowering of the lower belt or to a lifting of the upper belt from the lower flange. It is essential in this context that the material structure of the heart in the driving range of the upper belt and the lower belt is not destroyed in the connection of the upper belt with the lower belt by the further connection. The top and bottom chords are therefore never welded together on top of the center piece.
  • the bottom - On the side facing away from the grooves of the heart - the bottom - but it is of course possible to cohesively, for example, by welding, to connect or fix the upper belt and the lower belt together.
  • the upper flange and the lower flange are positively and / or non-positively and / or frictionally connected or fixed together.
  • a preferred embodiment of the invention provides that the upper flange and the lower flange is screwed by means of a support plate from below or laterally and / or welded and / or clamped.
  • the platen itself can be embedded in the track bed or connected to the sleepers.
  • the top flange and the bottom flange are the end of the grooved rail strands preferably non-positively and / or positively connected, so that there is no change in the material structure in the region of the connection point, namely at the transition of the driving groove of the grooved rail to the driving groove of the heart.
  • a carrying or machining of the upper belt and / or the lower belt and the ends of the grooved rail strands are provided so as to pass through the upper belt or the lower belt to connect an L- or S-shaped connection with a positive fit to the ends of the grooved rail strands,
  • the upper flange and the lower flange are preferably aligned on the underside in the assembled state of the frog, in order to facilitate the laying on or in the track bed and to ensure a secure fixation of the heart in the track bed.
  • the pressing of the lower belt of the upper belt when crossing the heart by the wheel of a train is difficult.
  • the fixation of the upper belt and the lower belt in the track bed can be done for example by screwing or by clamping at a threshold with a clamping plate or the like.
  • the upper belt and the lower belt should, at least in the groove area, consist of a tempered steel with high dynamic material properties, preferably of bainitic chromium and / or nickel and / or molybdenum-containing steel, in particular 17CrNiMo 6, CrMo 17 or manganese hard steel.
  • the upper belt and / or the lower belt may be designed for connection to a plurality of lower belts and / or upper belts.
  • a centerpiece to be connected to the ends of the grooved rail strands is provided in the crossing region such that the core piece is formed in a block-like manner, that the core piece on opposite sides in each case at least two Terminal areas for connection to two ends of a first grooved rail and each at least two terminal areas for connection to two ends of the first grooved rail crossing second grooved rail and having the terminal areas at least substantially without structural changes can be connected in the groove area with the grooved rail strands, preferably form-fitting outside of the driving groove area.
  • the above-described embodiment is based on the basic idea to carry out the connection of the intersecting grooved rail strands to the heart in such a way that at least in the region of the grooves does not lead to a structural change of the tempered steel by a thermal processing.
  • the grooved rail strands, at least in the driving groove area are not welded to the frog, the connection of the grooved rail strands to the frog being able to take place, for example, by L-shaped or S-shaped form-locking connections.
  • Fig. 1 shows a grooved rail intersection 2 having a plurality of grooved rail intersection areas 1.
  • the grooved rail intersection 2 comprises according to FIG Fig. 1 four intersecting tracks I to IV, each having two grooved rail strands a, b and rest on sleepers 3.
