Definitions

  • the present invention refers to a steel road safety barrier, for motorcycle accidents.
  • guardrails roadside safety barriers
  • This type of safety barrier generally comprises a corrugated steel strip carried on spacers which are mounted projectingly on uprights or posts spaced out along the road.
  • the corrugated steel strip is generally disposed at a height of about half a metre from the road surface. Therefore, the bottom part of the uprights is exposed up to a height of about half a metre.
  • Safety barriers are a valid means of containing vehicles or heavy vehicles swerving off the road, but they often do not guarantee the same performance for motorcyclists who come off the road following various types of accidents and even help to make the consequences of the accident more serious, causing severe injuries to the motorcyclist.
  • a safety system which provides for the insertion on existing safety barriers of a protective element of a soft material (polystyrene, polyurethane or similar materials) which covers the post, lessening the impact therewith.
  • a protective element of a soft material polystyrene, polyurethane or similar materials
  • these protections present some drawbacks. In fact, although they are very simple to install, they are not very durable and usually have to be replaced every four years. Furthermore, the protection of the post by means of systems of this type loses its efficacy if the impact takes place at high speed and does not prevent the possibility that the motorcyclist may slip under the strip of the safety barrier or possibly exit the road surface.
  • safety systems for motorcyclists are known to the art which provide for a second steel strip to be inserted in the bottom part of the safety barrier to prevent the motorcyclist from colliding with the post or from slipping beneath the strip adapted for containing vehicles.
  • the new smooth strip does not have sharp edges or dangerous protrusions towards the outside, has a sufficient degree of containment (that necessary to contain a body going off the road) and does not impair the functioning of said safety barrier.
  • a similar system consists in using two polyethylene tubes which run beneath the main strip, suitably fixed to the supporting posts.
  • safety systems for motorcyclists consisting of modular elements of plastic material which, suitably connected to each other, surround the post and cover the part of the safety barrier beneath the main strip. Even if such a system ensures a greater lessening of the impact, thanks to the plastic element that surrounds the post, it presents some drawbacks due mainly to the use of plastic material which is of limited durability and of inadequate mechanical strength, especially in the event of the road having to be cleared of snow by means of a snowplough, which pushes the snow against the safety barrier. Furthermore, the assembly of these modular plastic elements proves excessively complex and costly.
  • Object of the present invention is to overcome the drawbacks of the prior art, by providing a road safety barrier for motorcycle accidents that is reliable and able to minimise the injuries suffered by a motorcyclist due to impact therewith.
  • Another object of the present invention is to provide a safety barrier for motorcyclists that is versatile, suitable to be installed on pre-existing road safety barriers and able to adapt to a winding course.
  • Yet another object of the present invention is to provide such a barrier that has a long durability and at the same time is cheap and simple to produce and to install.
  • the road safety barrier for motorcycle accidents comprises:
  • safety barrier for motorcyclists, being made of sheet steel, ensures a greater durability than the plastic safety barriers of the prior art. Furthermore it can be adapted perfectly to the existing safety barrier.
  • the road safety barrier 1 for motorcycle accidents is applied to an existing safety barrier 100, such as, for example, that described in the paten application EP 1 213 391 .
  • the safety barrier 100 comprises a plurality of uprights 101 fixed to the ground T and spaced out along the length of the safety barrier, a spacer 102 mounted on each upright and a plurality of segments of corrugated steel strip 103 carried by the spacers 102.
  • Each upright or post 101 is preferably a C-shaped section, with the arms of the C disposed along the length of the road, that is, in the direction of travel of the vehicles, indicated by the arrow F in Figure 1 .
  • the uprights or posts 101 can be fixed to the ground T in any known manner, for example they can be fixed into a reinforced concrete element A, as shown in Figure 2 .
  • the bottom edge of the corrugated strip 103 is about half a metre from the ground T, or 442 mm to be precise. Therefore, the road safety barrier 1 for motorcyclists must be disposed in the space between the ground T and the bottom edge of the corrugated strip 103.
  • the barrier 1 comprises a plurality of segments of steel strip 2, suitably shaped and fixed to the existing posts 101, by means of special deformable steel spacers 3.
  • the strip 2 is obtained from a galvanised, cold-folded sheet steel, preferably having a thickness of about 2 mm.
  • the strip 2 is substantially square wave-shaped in cross section and has two ribs 20 which protrude towards the road with respect to a flat intermediate portion 21, in order to increase the stiffness of the strip.
  • Each rib 20 has a substantially trapezoid profile and consists of a flat surface 20 disposed between two oblique sides 22.
  • the joins 23 between the flat surfaces 20 and 21 and the oblique sides 22 are suitably rounded, so as to avoid sharp edges.
  • the width of the flat surface of the ribs 20 is slightly less than the width of the flat surface of the intermediate portion 21.
  • the thickness and the shape of the strip 2 have been specially designed to reach a compromise between a sufficient mechanical strength to withstand the impact against vehicles and at the same time to minimise the inertia and the stiffness of the resistant section, so that it can be deformed softening the impact of a motorcyclist.
  • the height of the strip 2 measured from its bottom edge to its top edge is about 384 mm. In this manner almost all the space between the road surface T and the bottom edge of the upper barrier 103 is covered.
  • the posts 101 are generally spaced out from one another with a centre distance of 2 m or less.
  • the length of the strip 2 is greater than 2 m, preferably 2.1 m.
  • pairs of holes 24 or of slots 25 are formed, having a centre distance equal to the centre distance of the posts 101, to allow the fixing of the strip 2 to the spacers 3 by means of screw or bolt means 5 ( Figure 3 ), as will be described below.
  • a plurality of pairs of holes can be provided, so as to be able to adapt the strip 2 to different centre distances of the posts 101.
  • the spacer 3 is obtained from a galvanised, cold-folded sheet steel, preferably having a thickness of about 3 mm.
  • the spacer 3 is substantially square wave-shaped in cross section and has two ribs 30 and 31 defined by flat surfaces.
  • the first rib 30 has a rectangular profile, so as to define a C-shaped seat able to accommodate the post 101, which is C-shaped in section.
  • the first rib 30 is defined between two sides 31 and 32 at right angles with respect to the flat surface 30 thereof.
  • the side 31 continues with a flange or intermediate flap 33, bent at a right angle with respect to the side 31.
  • the side 32 continues with a flange or intermediate flap 34, bent at a right angle with respect to the side 32.
  • the second rib 31 is defined between an oblique side 35 which joins to the intermediate flap 34 and an end side 36 at a right angle with respect to the flat part 31 of the second rib.
  • a first pair of holes 37 is formed on the end flap 33, a second pair of holes is formed on the intermediate flap 34 and a third pair of holes 39 is formed on the end side 36.
  • the first rib 30 of the spacer 3 is disposed to abut against the post 101, then the spacer 3 is fixed to the post 101 by means of one or two rectangular plates 4 fixed to the spacer by means of screw or bolt means 41 (schematised with a dashed line) which engage in holes in the plate 4 and in the holes 37 and 38 of the end flap 33 and of the intermediate flap 34 of the spacer 3.
  • screw or bolt means 41 (schematised with a dashed line) which engage in holes in the plate 4 and in the holes 37 and 38 of the end flap 33 and of the intermediate flap 34 of the spacer 3.
  • the post 101 is clamped between the spacer 3 and the closing plate 4 which abuts against the edges of the post 101.
  • the end side 36 of the spacer faces towards the road.
  • the end edges of the two segments of strip 2 are placed one over the other, so that the slots 25 of a first segment of strip are placed over the holes 24 of a second segment of strip and are disposed coaxially to the holes 39 of the end side 36 of the spacer.
  • the flat intermediate part 21 of the strip abuts against the flat end side 36 of the spacer.
  • the bolts 5 are then inserted in the aligned holes 24, 25 and 39 and are tightened.
  • bolts with a rounded head 50 disposed in the intermediate part 21 of the strip are used, so as to avoid sharp-edged protrusions.
  • the head 50 of the bolt is disposed on the intermediate part 21 between the two ribs 20 of the strip.
  • the tightening of the bolts 5 takes place by means of a nut 51 and of a washer 52 disposed on the end side 36 of the spacer.
  • this solution which provides for fixing only with two bolts, allows portions of road with somewhat accentuated bends to be covered.
  • the segments of strip 2 are deformed according to the radius of curvature of the bend and on tightening the bolts 5 sufficiently, no sharp edges are left between the two segments of strip.
  • the spacer 3 performs two important functions. In fact it keeps the strip 2 at a distance from the post 101, avoiding serious consequences in the event of impact of a motorcyclist against the strip 2 at the post 101. Furthermore, the particular shape of the spacer 3 allows deformation thereof, through the bending of the oblique side 35, in the event of impact, so as to absorb the impact gradually.
  • Figure 8 shows a terminal element 6 of the strip 2.
  • the terminal element 6 comprises an end portion 60 which has the same profile as the strip 2, in cross section.
  • the end portion 60 has a flat intermediate part 61 in which two holes 62 are formed, having the same centre distance as the pair of holes 24 in the strip 2.
  • the end portion 60 is joined to a U-shaped portion of curved sheet metal 63 which continues with a rectangular plate 64, the end flap 65 of which is bent at 90° and has two holes 66 having the same centre distance as the holes 37 of the spacer.
  • the curved part 63 of the terminal surrounds the post 101 and the end flap 65 of the terminal abuts on the end flap 33 of the spacer.
  • the holes 66 of the end flap of the terminal are disposed in register with the holes 37 of the spacer. Then bolts are inserted in the holes 66 of the terminal and in the holes 37 of the spacer to fix the terminal to the spacer 3, which is fixed to the post 101. It should be noted that the curved part 63 of the terminal surrounds the post 101 and is kept at a suitable distance therefrom, to avoid an impact of the motorcyclist against the post.
  • the spacer 3' is essentially similar to the previously described spacer 3.
  • the spacer 3' is obtained by cutting a part of the side 31 of the spacer 3, so as to obtain an end side 31' shorter than the other sides 32 and 36.
  • the end flap 33 is not present in the spacer 3'.
  • the pair of holes 38' has been moved to coincide with the join between the central flap 34 and the side 32, instead of being provided in a central position of the central flap 34.
  • the rib 30 of the spacer 3' is disposed in abutment against the post 101 and the spacer 3' is fixed to the post by means of two U-bolts 7 and of two respective closing plates 8 ( Figure 14 ) provided with holes 80 with a centre distance equal to the centre distance of the threaded ends 70 of the U-bolt.
  • one end 70 of a U-bolt is inserted in the hole 38' of the spacer and the two ends 70 of the U-bolt are inserted in the holes 80 of the respective closing plate.
  • Nuts 81 are then screwed onto the threaded ends 70 of the U-bolt so as to clamp the closing plate 8 in abutment against the ends of the post 101.
  • a washer 82 can be interposed between the closing plate 8 and the nuts 81.
