Definitions

  • the invention pertains to a road safety barrier intended to be supplemented with means for ensuring the safety and integrity of vehicles moving on the roadway side of public roads.
  • various objects or assemblies of objects functioning as safety barriers are provided.
  • the barrier must be robust enough to stop the vehicle while simultaneously being sufficiently elastic to absorb the impact shock through the deformation of the barrier without significantly deforming the vehicle, thereby ensuring maximum protection for the occupants inside.
  • barriers consist of an assembly of individual units. These units are primarily composed of a post, a spacer/damper, and a rail.
  • a high-impact resistance safety barrier designed to withstand collisions with any vehicle.
  • the posts are constructed from heavy metal profiles with high impact resistance, such as HEA or HEB profiles, I profiles, C profiles, OMEGA profiles, and so on.
  • the solution presents the disadvantage of a complex construction, high metal material consumption, and a risk of severe deformation upon vehicle impact.
  • a solution is also known that involves sets of prefabricated pieces made of recycled rubber, which are introduced into an infrastructure through either stacking or connecting as applicable by using an appropriate binder.
  • the drawback of this solution is that it is complex, entails high implementation costs, and is particularly unusable during the cold season when the materials used (such as rubber) lose their elasticity and become brittle.
  • a known solution used as a protective barrier is applicable also to the areas adjacent to access roads, in which water is utilized as ballast for the component parts.
  • the drawback of these barrier solutions lies in their complete ineffectiveness during the winter season when the water freezes.
  • the road safety barrier consists of a set of supporting posts made of tubular profiles, fixed at one end to the roadside embankment, a cross rail for each pair of supporting posts, and a collar-damper-spacer assembly consisting of two cylinders of different diameters and different wall thicknesses.
  • One cylinder is placed inside the other and positioned eccentrically to the maximum extent, with the interior cylinder having a greater wall thickness.
  • These cylinders are arranged in contact tangentially and welded along one generatrix.
  • An additional outer cylinder is added, with its wall cut along the generatrices and two flanges bent back to form a collar that attaches to the post of the barrier using bolt and nut assemblies.
  • the outer cylinder of the damper is fixed to one end of the transverse rail.
  • the column pipe is filled with concrete from the fixed end to the free end.
  • the barrier according to the invention consists of repetitive elementary portions as shown in Fig 1 . It comprises a supporting post 1 made of a tubular metal profile with one end featuring a metal plate 2 that is welded, perforated at the corners, and secured to the road embankment with metal anchors 3 that penetrate through it. Additionally, it includes a rail 4 and a collar-damper-spacer assembly as illustrated in Fig.3 , which connects the rail to the post.
  • FIG. 1 the safety barrier and its construction method are illustrated.
  • the barrier posts 1 are positioned and secured to the roadway side using dowels 3. Subsequently, the posts 1 are filled to the free end with concrete 6 of suitable consistency for this application, such as an intermediate concrete grade C16-20, introduced using specialized transport and pumping equipment such as a concrete mixer.
  • concrete 6 of suitable consistency for this application, such as an intermediate concrete grade C16-20, introduced using specialized transport and pumping equipment such as a concrete mixer.
  • post 1 through concrete filling can be carried out either on-site, on the ground, or at the manufacturing factory. This process is followed by securing the post to the road shoulder using metal dowels 3.
  • the collar-damper-spacer assembly as in Fig.3 , consists of two cylinders of different diameters and different wall thicknesses, designated as 7 and 8.
  • One cylinder is placed inside the other and positioned eccentrically to the maximum extent such that the two cylinders are in contact tangentially, aligned along a generatrix.
  • the outer cylinder 7 has thin walls, for example, 3 mm thick, while the inner cylinder 8 has thicker walls, for example, 6 mm thick.
  • the two cylinders are welded together along their length with a weld seam 11, executed using a conventional method such as MIG (Metal Inert Gas) - MAG (Metal Active Gas) welding with a wire diameter of 0.8-1.0 mm.
  • MIG Metal Inert Gas
  • MAG Metal Active Gas
  • the outer cylinder 7 is provided with holes 10, and diametrically opposite on the exterior of cylinder 7, in line with the contact area between the two cylinders, another cylinder 12 is welded using a separate weld seam 9 in the same manner.
  • This additional cylinder 12, made from an open metal pipe with two flanges on the side opposite the weld, is equipped with holes and serves as a collar that allows the entire assembly to be secured to the post 1 of the safety barrier as shown in Fig.1 .
  • the assembly is firmly secured using bolt and nut assemblies 13, as illustrated in Fig.2 .
  • the rails 4 are mounted through the holes 10 on the outer cylinders (see Fig.3 ) using bolts and nuts 14 as shown in Fig. 2 .
  • a top view of the pillar-collar-damper-spacer assembly with the rail 4 installed is provided.
