Definitions

  • This invention concerns a metallic safety barrier as set forth in the main claim.
  • the invention is used both as a traffic divider and also as a side element in streets where vehicles pass; it is used particularly to prevent or at least limit the vehicle from leaving the carriageway following accidental detours, thus preventing the vehicle from crossing into the opposite carriageway or from leaving the road.
  • the state of the art covers a plurality of barrier elements used on the roads, in particular motorways or freeways, both as elements to separate the carrriageways where the traffic goes in opposite directions, and also as an element to delimit the side of the road.
  • the state of the art covers, among others, the type of barriers known as "New Jersey", which are made by assembling, in series, modular elements made of concrete, which are made solid with each other and with the surface of the road.
  • the state of the art also covers metallic barriers which have the same conformation as the concrete type, but are resistant and light which makes them preferable, particularly for use on bridges, viaducts and other structures which require safety means with a limited weight; moreover these metallic barriers have better qualities with regards to assembly, replacement, maintenance, transport, shock absorption, etc.
  • the upper part of the anchor means In order to prevent these anchor means from being broken due to the heavy stresses to which they are subjected in the event of any impact from vehicles striking the barrier, the upper part of the anchor means generally cooperates with a hollow chamber included on the surface of the road or on the floor slab of the bridges or viaducts.
  • the hollow chamber allows the tie bar, when stressed by a particularly violent impact, to bend at the top but not break and therefore the barrier remains anchored to the ground.
  • a particularly violent impact such a construction is disclosed, for example, in WO 95/03453.
  • the hollow chamber is filled with elastic material which gives the hollow chamber a shock-absorber effect which improves the resistance of the tie bars.
  • a first disadvantage of this solution is that it is long and laborious to make the hollow chambers for the tie bars to bend in.
  • the purpose of the invention is to provide a barrier for use on the roads which is able to give a high level of safety and strength and particularly to ensure an efficient anchorage to the ground and a high level of shock absorption.
  • a further purpose is to allow the barrier to be installed easily and quickly, and to allow an equally rapid removal which will leave no traces on the road surface, once cleared, of structural elements or holes which could create problems during normal driving and/or constitute a potential danger for drivers themselves.
  • the barrier according to the invention consists, in a substantially conventional manner, of a plurality of metallic modular elements which can be connected to each other so as to constitute a continuous barrier.
  • the modular elements include, at their lower part, at least in correspondence with the transverse stiffening elements, seatings to house the means to anchor the barrier to the ground, such as tie bars, nails, screws or likewise.
  • the seatings inside the barrier and in the proximity of the supporting surface, the seatings include a hollow chamber of a conformation which, when placed in cooperation with the upper part of the anchor means, allows the latter, when subject to stresses caused by violent impacts, to be elastically deformed, at least in their upper part, so as to prevent them from breaking.
  • the hollow chamber is made directly during the step when the modular element is being prepared, thus avoiding the need for auxiliary work when the barrier is actually installed.
  • the hollow chamber is defined by a pipe, the size of which is at least three times greater than that of the anchoring tie bar, and which includes at its upper part a closure plate on which the attachment nut of the tie bar rests.
  • the chamber is filled with elastic material to obtain a better dissipation of the kinetic energy derived from the impact, thus reducing the mechanical stresses to which the anchor means are subjected.
  • the metallic barrier according to the invention includes at the lower part through apertures which allow the rain water, which otherwise would accumulate on the road, to pass.
  • the through apertures are delimited at the upper part by the lower face of the metallic modular elements and at the side by the lower ends of the transverse stiffening elements connected to the ground.
  • the safety barrier according to the invention consists of a plurality of modular elements 10, one of which is shown partly in Fig. 1, placed adjacent to each other and reciprocally connected to each other and to the ground 12.
  • the modular elements 10 include a metallic bearing structure 13 which is hollow inside and equipped with the appropriate longitudinal stiffening elements 14.
  • the bearing structure 13 includes on the lower part, in correspondence with the transverse stiffening ribs 21, a plurality of pockets 15 to house the means 16 which anchor the barrier to the ground 12, in this case consisting of tie bars 17; the structure 13 also includes, at the upper part, uprights 18 to support modular rods 19 of vertical containment.
  • the pockets 15, in this case, are quadrangular in section and are equipped with water-tight covers 20.
  • the hollow chamber 23 consists of the inner volume of a cylindrical pipe 24 solidly associated with the plate element 22; the elements 26 to clamp the tie bar 17 cooperate with the upper end 24a of the pipe 24; in this case, the clamping means 26 consist of a metallic plate 27 and a nut 28.
  • the hollow chamber 23 is filled with an elastic element 11, in this case made of rubber, suitable to further dissipate the kinetic energy of the vehicles which hit the barrier and therefore to reduce the mechanical stresses on the anchor means 16.
  • the lower face of the transverse stiffening ribs 21 acts as a support for the entire safety barrier. It is thus possible to define, in the lower part of the barrier, through apertures 25 between two consecutive stiffening ribs 21 as the shell of the bearing structure 13 is raised from the ground 12 .
