Definitions

  • the invention relates to a protective barrier arrangement for roadways, in particular for use at the edge of the road, on the median strip or to secure danger spots, with a plurality of bottom-mounted uprights, which are interconnected by means of mutually parallel lower and upper longitudinal beams, wherein at the lower longitudinal spar in the area the stator deformation elements are fixed, which carry a parallel to the lower longitudinal spar extending guardrail, and wherein the deformation elements are each formed as a straight circular tube, the axis of which is vertically aligned.
  • Such a guard rail arrangement is for example from the WO 97/26411 is known and serves mainly to prevent crossing of the roadway edge by a strayed from the way vehicle. This is intended to prevent further endangering of persons in the vehicle, for example on embankments or on bridges.
  • such protective barrier arrangements also serve as a protective device for adjacent facilities such as, for example, collapse-endangered structures or the like. They are usually made of steel.
  • Such protective barrier arrangements are constructed from selectively coordinated individual elements connected in a certain way. These allow plastic deformation in certain calculable limits in order to be able to absorb the forces occurring during the impact. According to the WO 97/26411 this is done in particular by the deformation elements.
  • the longitudinal spars constitute a relatively stable barrier, which usually prevents a break-through of this restraint system by a distribution of the impact forces by means of the longitudinal spars on a plurality of stands.
  • the invention is therefore the object of developing a generic guard rail assembly such that it shows improved retention properties without losses in terms of the absorption properties of impact forces.
  • a protective barrier arrangement with the features of claim 1. This is characterized in particular by the fact that on the side facing away from the guard rail side of the stand, a rear reinforcing element is arranged.
  • the guard rail assembly can thus withstand higher overall loads, so that possible accidents with heavy-duty vehicles is taken into account.
  • the protective barrier arrangement according to the invention thus contributes to the security requirements All road users regardless of the total weight of their vehicles and thus the possible impact energy bill.
  • the invention also allows retrofitting existing guard rail assemblies, such as those from the WO 97/26411 are known.
  • the back reinforcing element is formed as a profile rail which connects the uprights to one another and is preferably fastened to each stand at the upper end.
  • This can be achieved with simple design measures significantly improved retention properties, since such rails have a high tensile strength. If, in the course of an accident, impact forces act on the protective barrier arrangement according to the invention, these are thus reliably distributed by means of the profile rail to a larger number of uprights. In this case, the stabilizing effect of the rail already starts with a small plastic deformation of the arrangement, since it is arranged on the side facing away from an accident site of the stand.
  • an underride guard rail is arranged, which is arranged substantially parallel to the lower longitudinal beam, wherein the underride guard rail is disposed on the same side of the stand, as the guardrail, as well as positioned closer to the footprint is as the guardrail.
  • the lower and upper longitudinal spar each formed of a C-shaped profile, which is fixed by means of a directly attached to the uprights fastening tab.
  • the present invention provides a genuine clamp connection by the direct fastening manner. This allows for enhanced bonding between the tread elements and the uprights, which in turn results in improved transmission of impact forces to adjacent stands.
  • the degree of deflection of the protective barrier arrangement according to the invention is thus reduced compared to the prior art. This is particularly advantageous in areas with limited space.
  • the stands are anchored in the ground by a bottom end thereof is sunk in the ground. This is a technically simple and widely proven anchoring the guard rail arrangement given.
  • the uprights are provided in one piece with a base plate, by means of which they are anchored to the contact area in each case.
  • This design is intended, for example, on bridges and has also proven itself many times.
  • the rear reinforcement is made by anchoring at least one stand on a serving as a rear reinforcing element adjacent structure. This makes it possible to absorb impact energies particularly reliably. This is particularly advantageous when limited space prevail. Suitable structures, for example Impact base, gantries, tunnel portals, etc. Also in this embodiment, a reduced evasive movement of the stand is achieved, at the same time the relevant building is protected by the inventive guard rail arrangement from damage.
  • the distance between uprights anchored to the structure and adjacent uprights fixed at the base is greater than the conventional stand spacing and greater than 1.33 m.
  • a guardrail is arranged, wherein the rear reinforcing member has a second upper longitudinal spar which is parallel to the other upper longitudinal spar on the back of the stator, and wherein the second guardrail by a second lower longitudinal beam is worn with deformation elements attached thereto.
  • This embodiment is particularly advantageous when used on two-lane roads with a median strip. Its compact shape also allows it to be used in narrow median strips.
  • the guard rail assembly according to the invention also provides an advantageous construction for these applications, depending on the side of the impact of the remote upper longitudinal spar as a reinforcing element allows improved transmission of the tensile forces on adjacent stands. This achieves a reduced system deflection in both directions.
  • the crash barriers are fastened to the uprights at different heights above the footprint.
  • the protective barrier arrangement thus formed can thus also be used on median strips on two-lane roads with lanes offset from one another in the vertical position.
  • the usually provided installation height of the guardrail of about 0.75 m with respect to the upper edge of the road can thus be provided here easily with a single system.
  • the length of the deformation element substantially corresponds to the vertical extent of the lower longitudinal spar.
  • the length of the deformation element substantially corresponds to the vertical extent of the lower longitudinal spar.
  • FIGS. A first embodiment of the invention in the form of a protective barrier arrangement 10 is shown in FIGS.

  • the guard rail assembly 10 further includes deformation elements 15, which are each secured in the region of the stand 11 on the lower longitudinal spar 13. They are designed as a straight circular tube and arranged so that its axis extends substantially vertically. Compared to those from the WO 97/26411 However, the deformation elements 15 are formed longer and dimensioned so that their length substantially corresponds to the vertical extent of the lower longitudinal spar 13, as can be seen from the figures known deformation elements. Furthermore, the deformation elements 15 have a larger diameter than the deformation elements known in the prior art.

  • the reinforcing rail 19 is positioned at the upper end of the stand 11.
  • the reinforcing rail 19 has external dimensions of 100 mm to 50 mm.
  • the deformation element 15 is thus first deformed in a conventional manner for absorption of the impact energy. If the force of the impact exceeds a certain extent, deformation of the stator 11 positioned closest to the point of impact finally results, this deformation energy being transmitted by means of the reinforcing rail 19 as tensile force to adjacent uprights 11.
