Definitions

  • the present invention relates to a protective barrier arrangement for a vehicle restraint system for securing lanes, comprising a protective plank strand extending along a longitudinal axis, a plurality of profile posts which can be anchored or anchored in a ground, and a plurality of spacer elements, by means of which the protective barrier strand can be coupled to the profile posts or, is coupled, wherein the protective barrier strand viewed in achsorthogonalen cross-section has a cross-sectional profile, which has at least one contact web and a relation to the contact web set back mounting web, wherein further each a spacer element in a connection region on a profile post via a connecting means releasably attachable or fastened, and wherein in each case a coupling device for attaching the protective barrier strand is provided on the spacer element on a protective plank strand facing the end of a spacer element ,
  • the vehicle restraint systems can be assigned to different safety categories. Serve for this purpose parameters that are determined by experiments.
  • One of these parameters is the so-called “stopping level”, which provides information about the stopping capacity and the ability to divert a collision vehicle of the respective vehicle restraint system, as well as the so-called “effective range” Construction of the vehicle restraint system calculated.
  • a parameter termed the "impact severity level” serves to estimate the load on vehicle occupants and, therefrom, an expected severity of injury upon impact of the vehicle on the vehicle restraint system.
  • a protective barrier system of the type described above is known from the prior art under the name distance protection plank (DSP) and is used today in many vehicle maintenance systems.
  • DSP distance protection plank
  • EDSP simple distance protection plank
  • DDSP double distance protection plank
  • guard rail arrangement which can be used for securing roadways in the median strip area.
  • This guard rail assembly is relatively expensive and therefore expensive to manufacture.
  • this guard rail has a different appearance from conventional crash barrier outer appearance and requires specially designed crash barriers.
  • a protective barrier arrangement of the type described in which the coupling device has a saddle element which rests against a surface element of the protective barrier strand facing the spacer element and surrounds the fastening web in the manner of a clip.
  • the protective barrier strand moves in the event of an impact within the saddle element as in a joint shell and thus despite an impact-related deformation of the guard rail assembly in the intended orientation to the impacting object, such as a vehicle remains.
  • a connecting this connecting strap is provided at the remote from the protective barrier strand end of a series of successive spacer elements.
  • the entire arrangement can be further stabilized.
  • individual spacers due to impact rotate about the post axis.
  • axial forces are distributed to the individual spacers of the series of consecutive spacer elements and thus prevents twisting individual impact due heavily loaded spacers.
  • the saddle element a further development of the invention provides that viewed in the axis-orthogonal cross-section it has a contact web and two obliquely projecting side webs.
  • This design is technically simple and therefore easy and inexpensive to produce, however, shows sufficient effect to the effect that the protective barrier is mounted on the saddle as in a joint shell on the spacer element and the mounting bar of the protective barrier strand in the saddle element even in a deformation of the post element or of the spacer is in an optimal orientation to the impacting object.
  • the saddle element is welded to the end face of the respective spacer element. An economically producible and yet stable attachment of the seated element to the spacer element can be achieved by welding the seat element to the respective spacer element at the front.
  • the saddle element fastening means in particular a through hole or a threaded bore, for attachment of the protective barrier strand has.
  • the protective barrier strand can detach selectively from the remaining components of the protective barrier arrangement and thus remain held by adjacent, not yet or only slightly deformed profile posts at the correct height with respect to the impacting object for power dissipation and for retaining the object ,
  • Such a release of protective barrier string and other components of the protective barrier arrangement works in the stems of a predetermined breaking point, for example by using suitable predetermined breaking screws for fastening the protective barrier strand to the respective spacer elements.
  • the spacer element can be supported on the ground via its end remote from the protective barrier strand and thus further support the protective barrier strand in the stems of a truss structure.
  • the predetermined length is to be measured depending on the installation situation of the guard rail assembly. In this case, it must be taken into account in which underground area and at what level the end of the spacer element remote from the protective barrier strand touches down when the profile post kinks and what height the protective barrier strand is to maintain in this case.
  • a development of the invention provides that the spacer element is provided in its connection region with a receiving profile which engages around the profile post in the assembled state. This allows a secure connection of spacer element and profile post can be achieved. In order to fasten both components to one another, these can have corresponding holes into which fastening screws can then be inserted.
  • this predetermined breaking screws are used, which allow a targeted release of the profile post and spacer element from a certain deformation load, for example, when the profile post is folded due to impact and has placed the spacer with his distant from the protective barrier strand end on the ground and the protective barrier strand under the Load by the impacting object further supported.
  • the guard rail assembly For easier installation of the guard rail assembly can be provided that on the receiving profile and / or on the profile post slip bottles are attached or attached. As a result, the insertion of the upper end of the profile posts are facilitated in the corresponding receiving profiles. In addition, the manufacturing tolerances can be made larger, which makes the production more cost effective.
  • the profile post considered in cross section has a rectangular C-profile, which is preferably at least partially open on one longitudinal side. It has been found that such a profile post compared to conventional profile posts with IPE 100 profile or Sigma profile reduces the risk of injury, especially for cyclists.
  • the profile post has at least one stiffening element, preferably a plurality of stiffening elements along its longitudinal direction.
  • the stiffening element is designed as a cross member, which is mounted inside the profile post, wherein the cross member is fixed with one end to the near-mounted in the assembled state of the guard rail side of the profile post, preferably welded, and with its opposite free end is arranged at a clear distance from the side facing away from the guard rail side in the mounting state of the profile post.
  • a further development of the invention provides that at the free end of the transverse strut an orthogonal to the longitudinal extent of the transverse strut supporting plate is attached, is preferably welded.
  • Such configured stiffening elements can in a collision situation initially to a profile-dependent deformation of the profile post.
  • further deformation of the profile post in the stiffening elements is difficult, so that the profile post a higher proportion of the impact can absorb forces occurring before it completely kinks.
  • a higher degree of containment for the vehicle restraint system can be achieved.
