Definitions

  • This invention relates to a temporary track grid support system for use in a new method of constructing a track for rail vehicles on a channel-shaped concrete track.
  • the rails are first loosely placed in a prepared channel-shaped concrete route and welded to the joints.
  • the rails lie every few meters on a provisional track holder.
  • the rails are then lifted by a machine by about half a meter and each rail, individual, loose threshold blocks are approached from below to the freely suspended from the machine and pre-adjusted rail and clamped form and locks with these threshold blocks.
  • After fine adjustment of the rails they are placed on a track grid support system together with the sleeper blocks. Thereafter, the channel-shaped concrete route is filled with concrete, including the threshold blocks, and at the end the track grid support system is to be removed again, for further uses.
  • the object of this invention is therefore to provide a suitable track grid support system, which allows the temporary fixation of the finely adjusted rails, so that they lie at the correct height in the concrete route, in the correct lateral position in Betontrassee, as well as in the correct inclination of the two rails against each set and adjusted.
  • the track grid support system should be able to be completely removed again after the concrete blocks have been embedded in concrete.
  • a track grid support system for temporarily finely adjusted supports of a track grid in a channel-shaped concrete track, characterized by an adjustable in length spacer rod, at its ends subsequent track support plates with clamping means for clamping a rail foot deposited thereon, and on the outside adjoining the track base support plates, longitudinally adjustable stabilizing rods with support brackets for resting on the concrete track edge, and by supporting spindles, which enforce the track base support plates with a threaded connection.
  • FIG. 1 the Betontrassee 45 shown with the threshold block assembly machine 36 in a cross section.
  • the sleep block assembly machine 36 travels on rubber tired wheels 41 on the lane 1 of the concrete runway 45.
  • the lane 1 is bounded on both sides by the side walls 2.
  • the sleeper-block assembly machine 36 also has horizontally-lying, rubber-tired wheels 44 on both sides thereof, which roll on the side walls 2.
  • the cyclically forward moving machine mounted the previously stored between the two rails 3 on the lane 1 of the concrete route sleeper blocks.
  • the threshold block gripper unit 40 grasps these threshold blocks 16 and shifts them under the two rails 3 which are suspended by a preceding track lifting machine and which continue to hold them in a suspended or hanging manner.
  • the Schwellenböcke 16 are docked from below to the rails 3 and clamped with clamping devices fixed to the rail feet of the rails 3.
  • a track grid support system is now required, which the rails 3 in well-defined Holds position until the concreting of the threshold blocks 16.
  • the gliding grid support system 16 should be able to be removed after setting in the threshold blocks 16, so that the support system can be reused in another track installation.
  • the FIG. 2 It consists of two vertically arranged spindles 47, which each carry a track base support plate 48 for lying on it next rail foot.
  • the two track support plates 48 are connected by a spacer bar 50 with threaded connection to the support plates 48. By turning the spacer bar 50, the distance between the two support plates 48 is adjusted.
  • On the outside stabilizing rods 49 are articulated to the track base support plates 48, which are provided at the end with support brackets 51, which are placed on the upper edges of the side walls of the concrete track 45.
  • the surfaces of the Track support plates 48 of the track grid support system are slightly inclined towards each other, namely, just so that the later running over rails have the required inclination of 1:37 to 1:43, that is on 37 to 43 height units above by one unit inwards inclined and that this inclination is perfectly fixed.
  • FIG. 3 shows a single track base support plate 48 with the inwardly adjoining spacer bar 50 and the outer subsequent stabilization bar 49.
  • the track base support plate 48 rests on a spindle 47 which tapers conically down, which allows their subsequent extraction from the hardened concrete. In the upper end, it has a thread with which it is screwed from above into the track base support plate 48 and at the top it carries a screw head.
  • the spacer bar 50 has two opposing notches 54, in which a wrench can engage to rotate the spacer bar 50 and thus to adjust the gauge.
  • This track base support plate 48 is in the course of installation of the track grid support system from below tension-free docked to the rail foot and then clamped to the rail foot.
  • the track base support plate 48 On the track base support plate 48 can be seen on its inside a guide groove 52 for the inner edge of the male rail foot, and on the outside of a pivotable clamping element 53 with clamping lever 55 for its pivoting.
  • the track base support plate 48 is brought from below to the rail foot, but with the clamping element 53 is rotated relative to the position shown by 90 ° in the counterclockwise direction.
  • the rail foot finds space on the track base support plate 48 and is fed on her, and its inner edge can retract into the guide groove 52.
  • the clamping lever 55 is pivoted by 90 ° in a clockwise direction and the clamping element 53 pivots over the outer edge of the rail foot, whereby the track base support plate 48 is positively and non-positively braced with the rail foot.
  • this not only the precisely prescribed gauge is highly accurately adjusted and fixed, but also the required rail inclination of 1:37 to 1:43.
  • FIG. 4 shows still the stabilizing rod 49 between the support bracket 51 and the track base support plate 48 in an enlarged scale.
  • the length of the stabilizing rod 50 can be fine-adjusted.
  • the stabilizing rods 49 are hinged to the outside of the track base support plates 48 about a horizontal axis pivotally.
  • the outboard support brackets 51 are pivotally connected to the stabilizing rods 49 via a horizontal axis.
  • the track grid support system can be adjusted precisely to the clear width of the channel in the concrete route 45, because yes, this clear width has a certain variation.
  • This track grid support system is laid using an assembly crane.
  • a lifting load limit ensures that the track grid support system is precisely raised from below to the rail feet without lifting the rails. This is ensured with a lifting load limitation on the assembly crane.
  • the individual elements of the track grid support system are pre-assembled assembled laterally on the Betontrassee 45 and then mounted by hand with the help of the assembly crane, at a distance of about 1.8 meters from support element to support element.
  • the track-foot support plates 48 and the spacer bar 50 connecting them are moved from below to the rail feet of the suspended rails 3 with the aid of the crane arm 43 and clamped with them as described.
  • the track grid including the mounted support system is grasped by means of a mechanical straightening frame and lifted slightly.
  • a measuring unit transmits the current position data of the raised track grating. With the help of winches, the track can be brought in the vertical and horizontal direction in the desired position.
  • the distance bar 50 is fine-tuned and the track is set to an accuracy of ⁇ 1mm and thereby the track grid is set up via track insurance points mounted on the concrete track by means of optical laser technology.
  • the grate is held in position and the threaded spindles 47 are turned over and placed on the tunnel floor in an absolutely tension-free manner until the lower ends of the spindles 47 touch the concrete line without tension.
  • the conical spindle bodies become specially greased, so that later, after setting in, they can be pulled out of the concrete again.
  • the screwing of the spindles 47 is accomplished by means of pneumatic screwdrivers whose maximum tightening torque is adjustable.
  • the straightening frame is relieved with the installation of the track grid support system and this now takes over the weight of the track grid.
  • the stabilizing rods 49 are adjusted and slightly spread by hand.
  • the achieved accuracy of the laid track grille is -10mm for the vertical, ⁇ 1mm for the superelevation, and the lateral accuracy of the track is ⁇ 20mm. This fixes the finished mounted track grid in perfect alignment of all the required values and is ready to be embedded in concrete.
  • the channel-shaped concrete track is poured with concrete including the sleeper blocks.
  • the fresh concrete is introduced by means of Betonverteilstation in the threshold compartments, distributed and compacted.
  • the concrete is smoothed by hand and reaches just below the top of the threshold blocks.
  • the concrete extends only to just below the track support plates 48 and the spacer rods 50.
  • the track grid support system 46 can therefore be removed completely and easily after curing of the concrete. For this purpose, it is gripped by a crane on the two spindles 47 and thanks to the conical and previously greased spindle body can be pulled out of the concrete.
  • this track rust support system 46 can be used again.
