Definitions

  • the invention relates to a joint between two longitudinal sleepers made of concrete of a track grate according to the preamble of claim 1.
  • Such a joint is from the DE 297 00 893 U1 known.
  • the existing longitudinal concrete sleepers on their front sides on vertical recesses, in which a projecting into the respective longitudinal threshold holding element projects.
  • the holding elements of two adjacent longitudinal sleepers are connected to one another by connecting elements.
  • the recesses are filled with flowable concrete, so that after hardening of the concrete results in a stable bond between adjacent longitudinal sleepers.
  • the object of the invention is to provide a joint of the type mentioned, which allows an improved and possible crack-free composite between the longitudinal sleepers.
  • the mutually facing end faces of the longitudinal sleepers are profiled by a toothing.
  • the toothing acts as a tongue and groove joint in shear force transmission and limits the length of cracks (e.g., shrinkage cracks) that can occur in the grout.
  • the toothing is formed by horizontal or vertical grooves.
  • the toothing can also be formed by vertical and horizontal grooves.
  • the grooves can also by corresponding projections on the end faces a Toothing can be achieved.
  • the grooves preferably have a trapezoidal cross section, but may also have other cross sections.
  • the holding elements can be rod-shaped cast-in anchors made of steel and the fasteners Zulageeisen, which abut the dowels and fixedly connected to these, preferably welded.
  • holding elements can also consist of cast-in U-shaped loops, which are connected by at least one bracket and associated trailing arms as connecting elements.
  • the length of the individual longitudinal sleepers is, for example, 6 m, with the longitudinal sleepers a rigid threshold strand of, for example, 30 m can be produced.
  • Parallel to each other longitudinal sleepers may be connected at their ends and in between at corresponding intervals via transverse webs.
  • FIGS. 1 to 6 Shown in FIGS. 1 to 6 are joints between two concrete longitudinal sleepers 10 and 10A of a track grating.
  • the longitudinal sleepers 10 and 10A have at their ends in each case on the front side a vertical rectangular recess 4 or 4A.
  • the longitudinal sleepers 10 and 10A are further profiled by a toothing 12.
  • the toothing 12 is formed by superimposed horizontal grooves 1 and 1A with a trapezoidal cross-section.
  • the recesses 4 and 4A protrude holding elements, which are concreted into the respective longitudinal sleepers and interconnected by connecting elements.
  • the protruding into the recesses 4 and 4A holding elements consist of U-shaped loops 2 and 2A, which are arranged side by side and embedded in the longitudinal sleepers.
  • the loops 2 and 2A each have a vertically extending center leg 3, 3A, which runs parallel to the respective end face 11 or 11A of the longitudinal sleeper 10 or 10A.
  • the longitudinal sleepers 10 and 10A are aligned such that their end faces 11 and 11A have a distance of 4 cm.
  • two rectangular brackets 5 are used, the transverse legs 6 and 6A parallel and at a distance from the center legs 3 and 3A of the loops 2 and 2A, respectively. They are attached with binding wire to the outer legs of the loops 2 and 2A.
  • transverse bars 7 and 7A are used and secured with binding wire.
  • the crossbars 7, 7A extend from loop 2 or 2A to loop 2 or 2A.
  • the rectangular bracket 5 and the cross bars 7 and 7A are the connecting elements for connecting the running as a U-shaped loops 2 and 2A holding elements.
  • the holding elements protruding into the recesses 4 and 4A consist of rod-shaped, round dowels 8 and 8A made of steel, which are arranged side by side or one above the other and embedded in the longitudinal sleepers 10 and 10A.
  • two juxtaposed dowels 8 and 8A are provided in the two longitudinal sleepers 10 and 10A, while in the embodiment according to Figures 5 and 6 in each longitudinal sleeper 10 and 10A two superimposed dowels. 8 and 8A are concreted in.
  • these Versions consist of the connecting elements of alloying iron 9, which abut the dowels 8 and 8A and are welded to them.
  • the space between the longitudinal sleepers 10 and 10A is filled with flowable, non-shrinking concrete. After curing of the concrete, a stable bond between adjacent longitudinal sleepers is present.
  • the serrations on the end faces of the longitudinal sleepers can also have another suitable shape and also the holding and connecting elements can be configured accordingly differently.
