Definitions

  • the invention relates to a crash barrier crash barrier for use in front of obstacles on motor vehicle traffic routes with a large number arranged in front of a concrete support Damping elements, which are caused by the impact energy absorbent device are connected.
  • a generic device for connecting damping elements is known from US-A-3,845,936.
  • the publication shows several crash barrier crash absorbers with in front lined up damping elements.
  • the damping elements are in Direction of traffic and with each other across the direction of traffic connected. Directly adjacent damping elements are on hers Top and bottom over an attached U, one Screw and a wedge-shaped counterpart firmly together jammed.
  • the damping elements that are perpendicular to the direction of traffic seen spaced are over each other two profile steels that slide into each other telescopically connected.
  • the sliding movement is controlled by a Screw and a counterpart within the section steels, which by a screw and by a spring on a wall the interlocking profile steels are pressed, difficult.
  • this connection device has however, the disadvantage that the section steels immediately Stop pushed together and thus a very rigid Connection of the two damping elements is created.
  • Another The disadvantage of this construction is that with a frontal or side impact the profile steels are slightly deformed and they become the desired ones due to the deformation no longer have energy-absorbing sliding properties, but are almost firmly connected. Is further it is unfavorable that the connecting device only on two spaced damping elements and not to directly adjacent or on more than two adjacent damping elements is applicable.
  • German patent application DE-A-2 816 487 discloses a crash barrier for the use of obstacles on motor vehicle traffic routes with a variety Damping elements arranged in front of a concrete support with each other by absorbing the impact energy Device are connected, the device being a transverse arranged to the direction of travel, at least two damping elements interconnecting cross rope, which to the Damping elements is fixed friction.

  • Fig. 2 shows the crash barrier crash barrier in elevation. At Impact of a vehicle on the tip of the impact damper would the damping elements especially in the head area Side are pressed and thus achieved no damping Effect for the impact of the vehicle.
  • Fig. 2 there are three Variations for connecting damping elements perpendicular to Direction of traffic shown, the impact energy occurring absorb.
  • At the top of the crash cushion head a first variant is shown, in which two directly adjacent damping elements 1 through the energy absorbing device connected to each other become. Directly to the left is the connection of two spaced damping elements 1 shown and two more Damping elements further to the left is an example of the connection of several damping elements, in this case three.
  • FIG. 3 shows the detail X from FIG. 2 the energy absorbing connector at spaced Damping elements 1.
  • the two damping elements 1 are connected to one another via a cross rope 10 connected.
  • the cross rope 10 is via a fastening 2 set in the damping elements.
  • the attachment 2 is made from a clamping piece 3, which by two opposite and to the other end of the cross rope 10 tapering Clamping rails 4.5 is held.
  • the clamping rails 4.5 are designed as U-profiles in this exemplary embodiment, which face and face each other with the opening Recesses on the top or on the bottom 6 to insert the clamping piece 3.
  • the recesses 6 can the shape of circular sections or another suitable Have shape for inserting the clamping piece 3.
  • the Clamping rails 4, 5 each have one on their end faces outside flange 7 and an inside flange 8 for connection to the damping elements 1.
  • the geometry of the outside flange 7 or inside flange 8 is for suitable connection with adapted to the damping elements.
  • the inside flange 8 as well the damping element 1 also has a through opening 13 on.
  • the through opening 13 can be as a bore or as U-slot leading down from above.
  • the outside Flange 7 and the inside flange 8 are with the damping element 1 via round-head screws 9 or via another cheap joining option, e.g. Welding, connected.
  • the round head screws 9 When using the round head screws 9 the outside flange 7 from the outside between the two Clamping rails 4,5 screwed to damping element 1.
  • the round head screws 9 are favorably positioned on the left and right of the clamping rails 4 and 5.
  • a clamp 3 e.g. a section from a solid wave serve which on the circumference with a radially inward directional threaded hole is provided.
  • a cable tension screw for receiving the cross rope 10 11 screwed in.
  • the cross rope 10 is for example connected to the cable tensioning screw 11 via a cable clamp.
