Definitions

  • the present invention relates to the technical sector relative to road safety systems used as passive containment barrier elements for containing in the road and/or carriageway vehicles which, incidentally or due to unforeseen causes, skid or deviate from their normal path trajectory, in this way preventing them from invading the opposite carriageway, or ending up out of the carriageway.
  • guardrails These road safety systems are commonly known as guardrails.
  • Guardrails comprise a series of uprights planted in the ground, at a certain distance one from another and at a side of both edges of the carriageway, and a series of undulated bands (for example having a double undulation or a triple undulation) which are fixed to the uprights in such a way as to be consecutive to one another, and then are reciprocally fixed to one another so as to form a continuous front and constituting the containment barrier.
  • undulated bands for example having a double undulation or a triple undulation
  • the undulated bands are made of a metal material, such as for example galvanised steel, and are designed so as to be able to elastically absorb an eventual impact caused by a vehicle impacting against a guardrail due to a skid.
  • the problem can arise that the end of the terminal band of a first guardrail is staggered and ill-positioned with regard to the end of the initial band of a second guardrail, considering a direction transversal of the edge of the carriageway (i.e. the end of the terminal band of the first guardrail is further away, in a transversal sense, than the edge of the carriageway while the end of the initial band of the second guardrail is in a closer position wth respect to the edge of the carriageway).
  • An aim of the present invention is therefore to disclose an interconnecting system of guardrails able to obviate the above-mentioned drawbacks and which enables creating an interconnection between the end of the terminal band of a first guardrail with the end of the initial band of a second guardrail with simple and immediate operations.
  • the set aim is obtained with an interconnecting system of guardrails in accordance with claim 1.
  • FIG. 1 illustrates, in a schematic perspective view, the interconnecting system of guardrails of the present invention, already predisposed, in which the system realises the interconnection between two guardrails, ends of which are distanced and staggered;

  • FIG. 4A and 4B illustrate, in relative schematic views in perspective view, other elements of the system of the invention, which once assembled to one another form a modular reinforcing group illustrated in figures 4C and 4D, in respectively a perspective view and a lateral view;
  • figure 5A illustrates the use and application of the modular reinforcing group of figures 4C and 4D
  • figure 5B illustrates the system of the present invention installed, for realising the interconnection between two guardrails, in which three modular reinforcing groups are used.
  • reference letter (S) denotes the interconnecting system of guardrails according to the invention in its entirety.
  • the interconnecting system (S) of the present invention is assembled in such a way as to be applied in any situation in which there is a need to carry out an interconnection between two guardrails (R1 , R2) which are distanced and staggered in a transversal direction with respect to the edge of the carriageway.
