Definitions

  • the invention relates to a track form part unit and a track body constructed therefrom for rail vehicles.
  • the track body can be assembled from prefabricated concrete parts or built entirely or partially in cast-in-situ construction, i. to be poured on a prepared surface at the construction site.
  • German utility model no. 203 06 978.1 describes the use of two concrete troughs cast in a precast concrete plant for receiving one rail profile each. With the help of several bridges, the troughs are attached at their intended distance to each other and placed on the ground before the area between and under the troughs is poured with concrete to complete the track body.
  • the connection of two prefabricated rail troughs through an in-situ concrete slab in the track center contributes to the avoidance of tensile stresses and cracks in the rail troughs.
  • this leads to a more complicated Installation since the rail troughs must be arranged at the intended distance and in a suitable orientation and held until pouring and setting the in-situ concrete slab.
  • the present invention provides a track forming unit having a first and a second track body molding.
  • Each of the track body moldings has a beam-like concrete body extending in a longitudinal direction and can receive a rail profile to form, together with the other track molding, a track body for guiding rail vehicles.
  • the concrete body of the two track body moldings are mutually parallel and spaced from each other.
  • the track body molding unit according to the invention further comprises a spacer disposed between the concrete bodies of the first and second track body moldings, which fixes the concrete bodies at a predetermined distance from each other.
  • the spacer may be formed as a rigid spatial framework or rolled section. This can prevent buckling of the spacer in the vertical direction or horizontally in the longitudinal direction, which would result in an undesirable change of the distance in the transverse direction.
  • the truss or roll profile is designed to withstand the stresses encountered in the manufacture, transport, placement on the subgrade, and concreting of the track form member assembly.
  • the at least one spacer is below the intended Beton PilllIESs between the two track body moldings arranged and is thereby poured in the construction of the track body in an in-situ concrete slab, with a given concrete cover of typically several centimeters can be maintained.
  • each track body molding preferably serves as a rail trough for receiving a rail section of a railroad track.
  • the concrete body on an upper side on a molded, running in the longitudinal direction rail recess. On one or preferably on both sides of the rail recess can extend parallel to this extending cheeks upwards.
  • the longitudinal direction of the concrete body extends substantially horizontally in the direction of the track course.
  • the concrete bodies are spaced apart from one another in a transverse direction, which is also substantially horizontal and transverse to the longitudinal direction, in order to maintain the track width.
  • a substantially vertical direction under the concrete bodies may be located as a base layer a planum on which the track body is constructed.
  • the cheeks on either side of the rail recess may extend upward below the upper edge of the rail profile.
  • the rail profile is usually sufficient pouring the lower part of the profile in a potting compound, while the upper part of the rail profile protrudes beyond the cheeks and arranged in the recess between them potting compound.
  • the flanges run in a free upper part of the gap between the rail profiles.
  • each concrete body higher than the outer cheek and advantageously higher than the upper edge of the rail profile or at least as high as this to form a derailment protection.
  • the inner cheek may thereby be more similar to a protective rail mounted in a conventional track with sleepers for allowing lateral guidance of a derailed wheel between the rail profile and the inner cheek.
  • a substantially horizontal flat runflat surface is formed in the manner of a step between the bottom of the rail recess and the inner cheek, which can serve as a tread the flange of a derailed wheel. This is particularly advantageous on hazardous sections, such as on and under bridges and in tunnels. In the Noterton formation a groove for receiving and lateral guidance of the flange can be configured established groove.
  • a step disposed between the outer cheek and the rail recess serves as a temporary tread for a derailed wheel.
  • the spacer can be two superimposed rigid have interconnected elements. This creates the opportunity to be able to absorb even moments about the longitudinal axis of the track body of the concrete bodies and to prevent tilting thereof by rotating about the longitudinal axis.
  • the two superimposed spacer elements can be loaded on pressure and / or train.
  • the spacer elements may include reinforcing elements projecting out of the concrete bodies.
  • the two superimposed spacer elements can be connected to an interposed triangular strut.
  • Triangular bracing are generally framework-like connection structures between the two spacer elements and the adjacent to their ends concrete bodies to understand, which extend in both the transverse and in the vertical direction, ie oblique or contain diagonals.
  • the spacer elements could also be connected to each other by a quadrilateral connection.
  • a rigid framework three or more substantially horizontal bars or straps of structural steel can be used, which are located vertically on at least two different heights and are preferably connected in pairs by means of triangular struts to form a lattice girder.
  • the lattice girder may have a triangular cross-section.
  • the bars may also be part of one or more mats or be arranged on this and / or parallel to their bars and connected to the steel mesh.
  • a rolled section can be used as a spacer.
  • a rigid, spatially extended structure is created as a spacer.
  • the framework of the spacer can be part of a reinforcement be cast in the concrete body of at least one of the two track moldings.
  • spacer elements are present, which are also cast in the concrete body of both track body moldings.
  • the concrete bodies are already poured together in a precast concrete plant with serving as spacers, connecting them common reinforcement elements. In this case, no further alignment with respect to the predetermined track width and a parallel alignment of the two track body moldings with respect to one another on the construction site need be made more on the construction site, as a result of which the number of degrees of freedom is considerably reduced. There are no additional, for example, from above in the rail recesses intervening bridges attached and later removed.
  • the framework of the spacer may be either two or more individual beams distributed over the length of the concrete body, e.g. Lattice girders act.
  • planar structures such as reinforcing steel mats, which can extend over the entire length of the concrete bodies in a substantially horizontal plane.
  • Two parallel mats can be stacked on top of each other and joined together with triangular braces to increase their flexural rigidity.
  • It can also be a rigid steel mat with one or more individual bars connected by triangular bracing rigid.
  • the welded mesh can be braided or welded.
  • the spacers preferably extend at right angles to the concrete bodies, so that they can counteract changes in distance between the concrete bodies essentially by means of pure compressive or tensile forces.
  • At least one of the concrete bodies has a height adjustment device for adjusting the final height of the concrete body above the ground and for securing the concrete body at this height.
  • a concrete body contains at least two height adjustment devices distributed over its length in order to be able to set the desired course of the rail height in the longitudinal direction and to be able to compensate for any deviations or irregularities in the height of the surface.
  • the concrete body of both track body moldings include height adjustment devices to adjust the height of both concrete body independently relative to the planum. With two height adjustment devices per concrete body, the height profile of both track body moldings including any pitch can be specified, at the same time a possible bank of the track body are set.
  • the height adjustment device preferably includes a permanently mounted in the concrete body, for example, already cast during manufacture threaded sleeve and rotatably received in the threaded sleeve threaded bolt.
  • the threaded sleeve preferably extends in the vertical direction and may be arranged in the region of the rail trough. Preferably, viewed in cross-section, it passes approximately through the Center of gravity of the concrete body, so that when supporting the concrete body by the threaded bolt arranged in the threaded bolt no significant forces in the transverse direction, which could lead to tilting of the concrete body in the transverse direction.
  • the threaded bolt is adapted to be extended out of the concrete body by rotating downward to raise the concrete body to the desired height above the ground.

Then all track moldings are adjusted to the desired heights. Then lateral formworks are mounted in the concrete body, which can also be designed as a lost formwork and then remain on the track body. Depending on the location and height of the track moldings, these can themselves serve as formwork or an essential part of the same. Subsequently, by pouring fresh concrete into the space between and under the track moldings, an in-situ concrete core is poured which extends upwardly beyond and encloses the spacer.
