Definitions

  • the invention relates to a restraint system for carriageways, which has posts fixed to the ground and to the posts, incorporating spacers, spars, according to the preamble of claim 1.
  • This restraint system consists of vertical posts with foot plates, which are fixed on the structures. Horizontal security elements as a handrail are connected to the posts. The spars are connected via spacers or damping elements in each case with the posts. Between the posts are also pressryogllungen attached. Even if the distance or damping elements in various ways with the posts or the bars can be connected, an advantageous connection is seen in a screw connection.
  • the fastening by means of screws is simple, reliable and easy to assemble and repair.
  • the upper damping elements consist of a steel profile in the form of an inside open '8' and are similar to two extended by an arc 'S', whose ends are connected by two webs. These three semicircles of the extended by an arc 'S' are pushed together on impact by a vehicle and thus dampen the impact energy.
  • the inner and outer bows can be adapted to the requirements in terms of size and position.
  • these damper webs each have two outgoing arches and an inward going arc.
  • the transition between the mounting webs and the damper webs is evenly through the first arc between the two mounting webs of the damping element and the vertical post or the inner leg of the spars can be mounted to increase the load bearing capacity in each case a feed element.
  • a feed element is mounted only between the damping element and the inner leg of the spars.
  • the chuck element has at least two holes and is clamped by the guard rail screws between the damping element and the inner leg of the guard rail spars.
  • the lining element may be made of a metallic material z. B. steel but also be made of plastic or rubber.
  • This basic structure is designed so that it can be easily modified according to the locally required retention level.
  • this restraint system can be used both on a median strip between two driveways as well as the edge of a guideway.
  • the construction of the restraint system is simple and economical.
  • the used damping elements fulfill their function reliably.
  • the steel profiles of the damping elements can be efficiently produced in large quantities at low cost. In practical experiments, a very good start-up behavior was achieved.
  • An advantageous embodiment of the restraint system according to the invention is seen in that below the upper spar a second spar is arranged. This embodiment is preferably used when an underrun protection is required in addition.
  • the upper spars can be usefully attached at a mean height Ho of 500 mm to 800 mm to the driveway, preferably they are mounted at a mean height Ho of 600 mm to 700 mm.
  • the lower spars can be usefully attached at a mean height Hu of 130 mm to 370 mm to the driveway, preferably they are mounted in a mean height Hu of 200 mm to 300 mm.
  • a handrail which is connected to the upper ends of the posts can be provided on the restraint system.
  • the damping elements may consist inter alia of a special hollow profile or of a material with steel-like properties.
  • the shape of the special hollow profile can be z. B. be an inside open 8 or 6-or 8-square and / or these shapes similar profiles.
  • restraint system consists of edge of a roadway or corresponding structures in the ground anchored foot plates (5).
  • the foot plates (5) are z. B. by dowels (8) attached to the roadway or corresponding structures.
  • the vertical posts (4) are mounted on the foot plates.
  • stiffening plates (9) are mounted between the foot plate (5) and the posts (4) on the side not facing the roadway.
  • the required tolerance compensation (7) to the structure is made using a mortar layer, rubber plates or other plastic plates. Preferably by EPDM plates.
  • the spars (2a, 2b) are formed from weft-wise juxtaposed profiles (shots), which have a U-shaped, W-shaped or similar configuration in cross-section.
  • the distance or damping elements (3a, 3b) are horizontal in their effective direction (see Fig. 1 ) attached to the post.
  • Each post (4) consists of an I, C or similar profile (eg closed).
  • the central web of the profile extends transversely to the bars (2a, 2b).
  • the spacer or damping elements are screwed or attached with other fasteners.
  • FIG. 2 shows the restraint system in a horizontal view from the roadway in the direction of impact and FIG. 3 shows the restraint system from above.
  • the spars (2a, 2b) are, as described above, fixed in two different heights.
  • the upper spar (2b) is closer to the track than the lower spar (2a).
  • the spars (2a, 2b) can also be mounted at the same distance from the roadway and the lower spar (2a) can be closer to the track than the upper spar (2b).
  • the ratio of the distance Ao of the front side of the upper tie rod (2b) from the post (4) to the distance Au of the front of the lower tie rod (2a) to the post (4) is in a range between 3.0: 1 to 1.0: 1, preferably 1.94: 1.
  • the upper and lower damping elements (3a, 3b) used on the upper and lower spars (2a, 2b) may be the same or different in shape, size and rigidity.
  • a lining element Between the two fastening webs (14) of the damping element (3a, 3b) and the vertical posts (4) and the inner leg of the spars (2a, 2b) can be additionally mounted to increase the load-carrying capacity in each case a lining element.
  • a lining element Preferably, only between the upper damping element (3a) and the inner leg of the upper spars (2b) a lining element (11) is mounted.
  • the chuck element (11) has at least two holes and is clamped by the guard rail screws between the upper damping element (3a) and the inner leg of the upper spars (2b).
  • the lining element (11) can be made of a metallic material such. B. steel but also be made of plastic or rubber.
  • the upper spar (2b) is first contacted in each case.
  • the first damping elements (3a) of the upper spar (2b) are deformed, as a result of which impact energy is dissipated.
  • the posts (4) remain largely unencumbered in this deformation phase.
  • the upper spar is thereby displaced so far in the direction of the posts (4) until the repellent away from the track back / surface on the post (4) is applied or the damping element is completely compressed. In this way, the post (4) until then largely without large force influence. Only in a second deformation phase, the force on the post (4) goes over. However, the protective function is still maintained despite a strong Auffahrbelastung.
