Definitions

  • the object to which the invention protected by this Patent refers is a "Protective Strip" which prevents violent impacts against the metal profiles anchored to the asphalt where the corrugated plates which the guard rails are made of are secured, by absorbing most of the kinetic energy of the collision and leaving the driver and/or companion unharmed in most accidents.
  • guard rails or crash barriers which prevent vehicles from leaving the roadway, are manufactured in two parts; the upper part is a longitudinal beam of preferably corrugated galvanized steel and the other is a double T-shaped or U-shaped steel profile secured to the ground that keeps the longitudinal beams joined together.
  • guard rails have been devised as an element required for passive highway safety, helping to prevent a vehicle from leaving the roadway and falling down an embankment or crossing over to the opposite lane of a highway on losing control of the vehicle.
  • a crash against this type of protection can have fatal consequences for the health of the driver and/or companion.
  • Standard UNE135 900 is in charge of assessing the injuries suffered in special tests by a dummy (mannequins used in vehicle collision tests that simulate the behaviour of the human body in the presence of forces that appear during the collision) on crashing against a double bicorrugation protective system at different speeds. If a protection system conforms with the above mentioned standard, that system may be certified.
  • the purpose of the invention that comprises the object of this Patent is to eliminate the above described problem in an easy but efficient way, and it has been designed and developed in accordance with this priority objective.
  • the protective strip is made of a plastic, thermoplastic or similar material, preferably polyethylene, obtained in a single phase of rotomolding and practically hollow inside.
  • This strip has two end conduits, one upper and the other lower, each housing preferably metal hollow pipes that provide rigidity to the assembly.
  • this protective strip On the back of this protective strip are some indentations or angular recesses so that, in the event that an accident occurs, there will be a deformation on the surface of the impact at the same time that the indentations stretch in a vertical direction in order to absorb the kinetic energy that has not been absorbed on the front surface.
  • the protective strip is related to the double T-shaped or U-shaped metal profile secured to the ground by means of a metal bracket. It is also related to the lower part of the bicorrugation and equidistantly along the protective strip by means of another metal bracket. In the center of the protective strip, another metal bracket is secured to the bicorrugation for purposes of providing the latter with greater rigidity and consistency. The brackets are secured by using screws. The brackets that connect the protective strip to the back of the bicorrugation provide it with greater rigidity in its central areas and prevent the possible accident victim from crossing over the vertical of the guard rail.
  • the protective strip is 4 meters long, which is the length corresponding to the distance between each of the T-shaped or U-shaped profiles that are anchored to the ground and to which the corrugated plates or bicorrugations that make up the guard rail are fastened.
  • the protective strips are related to each other thanks to a prolongation of the material or overlap that they have at one of their ends and an indentation at the other.
  • the protective strip (1) is 4 meters long, which is the length corresponding to the distance between each of the T-shaped or U-shaped profiles (2) which are anchored to the ground and to which the corrugated plates (3) or bicorrugations that make up the guard rail are fastened. Therefore, one of these protective strips (1), which are related to each other thanks to a prolongation of the material or overlap (4) that they have at one of their ends and an indentation (5) at the other, must be placed every 4 meters.
  • the protective strip (1) is made of a plastic, thermoplastic or similar material, preferably polyethylene, obtained in a single phase of rotomolding and practically hollow inside.
  • This strip (1) has two end conduits, one upper (6) and the other lower (7), each housing preferably metal hollow pipes (8) that provide rigidity to the assembly.
  • this protective strip (1) On the back of this protective strip (1) are some angular recesses (9) so that, in the event that an accident occurs, there will be a deformation on the surface of the impact at the same time that the angular recesses (9) stretch in a vertical direction in order to absorb the kinetic energy that has not been absorbed on the front surface.
  • the protective strip (1) has an upper extension, taking on an angular, curved shape that, in the event of an accident, prevents cuts or any kind of injury to the driver as he/she does not come into contact with the metal of the guard rail.
  • the protective strip (1) is related to the double T-shaped or U-shaped metal profile (2) of the guard rail secured to the ground by means of metal brackets (10). It is also related to the lower part of the bicorrugation (3) and equidistantly along the protective strip (1) by means of other metal brackets (11). In the center of the protective strip (1), another metal bracket (12) is secured to the bicorrugation (3) for purposes of providing the latter with greater rigidity and consistency.
  • the brackets (10, 11, 12) are secured by using screws.
  • the brackets (11, 12) that connect the protective strip (1) to the back of the bicorrugation (3) provide it with greater rigidity in its central areas and prevent the possible accident victim from crossing over the vertical of the guard rail.
  • the material used to make the protective strip (1) is recyclable, which helps to reduce costs and also to achieve significant eco-efficiency.
  • the only maintenance required is limited to replacing the pieces damaged in the accident with new pieces, a job that anyone can do in just a few minutes.
  • the protective strip (1) can also be used as a beaconing system, since it can be manufactured in any color and can include reflecting marks to turn dangerous zones into duly signaled, non-risk zones.
  • the protective strip (1) can pass underneath the strip, thus preventing water from collecting on the highway and, indirectly, animals from accessing the highway in the case of mountainous locations.
