Definitions

  • the present invention relates to a road barrier with motorcyclists protection.
  • the present invention relates to a programmed-deformation, discontinuous road barrier with motorcyclists protection.
  • road barriers are fixed structures that are placed along the lateral edge of the carriageway and are adapted to hold, within the carriageway, a car or other vehicle for transporting goods and/or persons of medium to large dimensions, which should accidentally impact against the same road barrier.
  • guard-rails are basically made up of a series of supporting posts, which are made of metal and are driven into the ground in a substantially vertical position, one spaced side by side the other along the lateral edge of the carriageway; and of a series of ribbonlike cross-beams with a double- or triple-wave profile, which are made of metal, are fixed to the supporting posts in a horizontal position and one after the other, at a predetermined height above the ground, and are butt-fixed one to the other via special through bolts, so as to form a longitudinal retaining band, which extends seamlessly along the lateral edge of the carriageway.
  • the ribbonlike cross-beams with double- or triple- wave profiles are fastened to the supporting posts so that the longitudinal retaining band is roughly at the same height as the bumpers of cars and other vehicles for transporting goods and/or persons that travel on the roads.
  • the supporting posts and ribbonlike cross-beams with a double- or triple- wave profile are specifically structured and dimensioned to retain, within the carriageway, a car or other vehicle for transporting goods and/or persons of medium to large dimensions, which might accidentally impact against the road barrier in the event of an accident.
  • supporting posts and/or double- or triple-wave ribbonlike cross-beams sometimes have sharp edges that unfortunately can be lethal for the motorcyclist impacting at high speed.
  • a road barrier with cyclists protection which comprises, in addition to the traditional horizontal ribbonlike cross-beams with a double- or triple- wave profile, also a series of horizontal ribbonlike cross-beams with a fretted profile, which are arranged horizontally, spaced beneath the longitudinal containment band formed by the horizontal ribbonlike cross-beams with double- or triple-wave profile, and are fastened to the supporting posts of the road barrier by means of spacers with programmed-deformation structure, which deform in the event of impact by the motorcyclist.
  • a road barrier comprising, in addition to the traditional horizontal ribbonlike cross-beams with a double- or triple- wave profile, a series of straight metal section-bars with omega profile, which are arranged horizontally and one after the other, spaced beneath the longitudinal containment band formed by the horizontal ribbonlike cross-beams with a double- or triple- wave profile, and are fixed directly to the supporting posts of the road barrier by means of metal strips.
  • Aim of the present invention is to realise a discontinuous-type road barrier, which offers better protection to motorcyclists in the event of an accident and which is, at the same time, easy and cheap to install.
  • a road barrier with motorcyclists protection as defined in Claim 1 and preferably, though not necessarily, in any one of the claims dependent thereon.
  • number 1 denotes, as a whole, a road barrier adapted to be installed long the lateral edge of the carriageway, with the function of holding, within the carriageway, a car or other vehicle for transporting goods and/or persons of medium to large dimensions, which should accidentally impact against the same road barrier 1.

  • supporting posts 2 are preferably substantially straight and are preferably structured to be driven into the ground in a substantially vertical position.
  • the road barrier 1 could also be a bridge-side road barrier or similar.
  • the supporting posts 2 could be fixed directly to the reinforced concrete, advantageously by means of anchor plates and/or anchor bolts placed at the lower ends of the supporting posts 2.
  • the oblong cross-beams 3, on the other hand, are preferably substantially rectilinear and are preferably fixed rigidly to the lateral side of the supporting posts 2 preferably via the interposition of special connecting brackets 5 advantageously made of metallic material, which are preferably structured so as to keep the oblong cross-beams 3 roughly grazing the supporting posts 2.
