Definitions

  • the invention relates to a Leitschwellenstrang according to the features in the preamble of claim 1.
  • Such a Leitschwellenstrang counts by the DE 20 2005 008 391 U1 to the state of the art. It comprises between a concrete sliding wall with two superimposed, different slopes relative to the vertical roadway-facing inclined surfaces and a crash barrier arrangement with two mutually offset in height, supported by posts and shot-wise crash barriers a coupling profile made of sheet steel.
  • the concrete sliding wall is in particular one of the so-called New Jersey type.
  • the coupling profile has a first longitudinal section, which is adapted to the roadway-side contour of the concrete sliding wall. Accordingly, the first longitudinal section has a relative to the vertical only slightly inclined upper portion and a vertical to the upper and more inclined lower portion. At the bottom The area is followed by a vertically extending skirting.
  • the first length section merges into a wedge-shaped intermediate area which increases in area and ends in a recess whose depth essentially corresponds to the profile thickness of the guardrails.
  • the return is followed by a vertical supporting wall, which essentially corresponds to the height of the concrete sliding wall.
  • the guardrails are in front of the supporting wall and in the recess and are bolted here.
  • the invention is - based on the prior art - the object to provide a Leitschwellenstrang in which the coupling profile between the Betongleitwand and crash barriers can be manufactured with a low production cost and ensures a non-jump transition especially from the crash barriers on the concrete sliding wall.
  • the width of the lower region of the first longitudinal section of the coupling profile which is adapted to the lower inclined surface of the concrete sliding wall expires continuously narrowing into the lower corner of the vertical front side of the second longitudinal section.
  • an angle of about 15 ° is desired. In this way, starting from the concrete sliding wall, an ever softer coupling profile is created. An accident vehicle is therefore under Avoidance of bagging in the region of the coupling profile deflected yielding and can not bounce hard on the concrete sliding wall.
  • the coupling profile is provided according to claim 2 approximately in its longitudinal center a lying in front of the end face of the concrete sliding wall cross plate.
  • This transverse sheet welded to the coupling profile can be connected to the concrete sliding wall, in particular screwed to it.
  • a positive connection of the coupling profile can be achieved with the concrete sliding wall.
  • two superimposed groove-like nozzle are fixed with a trapezoidal cross-section on the side facing away from the front side of the concrete sliding wall side of the transverse plate.
  • This cross section corresponds to the cross section of trapezoidal stiffening profiles, which are provided on the rear side of the crash barriers in their likewise trapezoidally shaped middle height ranges. These stiffening profiles overlap the nozzles and are connected to these, in particular screwed. In this way, an additional stabilization of the coupling profile is achieved.
  • the crash barriers are connected in a conventional manner via spacer elements with the posts.
  • drawstrings extend to the concrete sliding wall and attached to the back of the concrete sliding wall, in particular screwed, are.
  • the Leitschwellenstrang 1 comprises a Betongleitwand 3 New Jersey type, a guard rail assembly 4 with two superimposed, shot-wise crash barriers 5 and a coupling profile 6 between the Betongleitwand 3 and the guard rail assembly 4th
  • the not shown in detail manner also consists of individual shots concrete sliding wall 3 has according to the Figures 3 and 8th roadway side opposite the vertical V slightly inclined upper inclined surface 7, a via a throat 8 subsequent, compared to the vertical V even more inclined lower inclined surface 9 and a vertically extending base surface 10 on.
  • the rear side 11 of the concrete sliding wall 3 also extends inclined to the vertical V, with an angle W, which corresponds to the angle W1 of the upper inclined surface 7 to the vertical V.
  • the crash barriers 5 of the crash barrier arrangement 4 are fastened to the roadway by spacer elements 12, which in turn are carried by pillars 14 which are rammed into the ground 13.
  • the posts 14 have a U-shaped or sigma-shaped cross section.
  • Each guardrail 5 is composed of several shots 5a ( FIG. 1 ) and has in the middle height region 15 a groove-like trapezoidal cross-section, to which the road side vertical leg 16 connect ( FIG. 8 ). End side of the flat leg 16 of the roadway 2 away bent bevels 17 are provided.
  • the trapezoidal in cross-section average height regions 15 of the guardrails 5 are encompassed by trapezoidal stiffening profiles 18, which, like the crash barriers 5, are assembled by the shot.
  • end faces 19 of the spacer elements 12 extend shot-wise composite drawstrings 20, which, like the FIG. 2 can recognize beyond the guard rail assembly 4 addition to the concrete sliding wall 3 extended and screwed to the back 11 of the concrete sliding wall 3.
  • the made of sheet steel coupling profile 6 has according to FIG. 8 a adapted to the roadway contour of the concrete sliding wall 3 first length portion 21 and a second length portion 22 with a flat portion 23 through which the coupling profile 6 is connected by means not shown screw 24 with the flat legs 16 of the crash barriers 5.
  • the coupling profile 6 overlaps with a horizontal leg 25, the top surface 26 of the concrete sliding wall 3. This leg 25th extends with increasing narrowing to the vertical end face 27 of the second length section 22nd
  • the planar region 23 of the second longitudinal section 22 of the coupling profile 6 extends in the same inclined plane E - E as the upper region 28 of the first longitudinal section 21 adapted to the upper inclined surface 7 of the concrete sliding wall 3 FIGS. 4 and 8th in that the width B of the lower region 29 of the first longitudinal section 21 of the coupling profile 6 adapted to the lower inclined surface 9 of the concrete sliding wall 3 narrows continuously into the lower corner 30 of the second longitudinal section 22 at an angle of 15 ° vertical end face 27 of the coupling profile 6 expires.
  • the upper region 28 and the lower region 29 of the first longitudinal section 21 are fastened via screwing means 31, not shown, to the upper and lower inclined surfaces 7, 9 of the concrete sliding wall 3.
  • connection pieces 36 can be coupled, in particular screwed, to the trapezoidal stiffening profiles 18 extending at the rear of the guardrails 5.
  • FIGS. 4 to 7 still recognize that the crash barriers 5 are pivoted over several shots 5a away from the inclined plane E - E of the second length section 22 of the coupling profile 6 in a plane E1 - E1 inclined in opposite directions.
