Definitions

  • the present invention regards the filed of road and motorway safety structures.
  • this invention is known as “the new jersey barrier”
  • these barriers are drawn two versions:
  • a road barrier In order that a road barrier can carry out its function to preserve as much as possible the life and the integrity of the drivers, that impact into. It is necessary the barrier can gradually absorb the kinetic energy of a vehicle and than:
  • the inventor in order to avoid above inconveniences, has conceived a new type of road barrier.
  • the metallic elements, that form the barrier are composed by covers with ribbed system that climb on with some stiffening rib, rails of reinforcement and some means of anchorage in the ground.
  • the assemblage of the various parts and the connection to the ground are effected through the fastening of means filleted. These parts are shaped, dimensioned and positioned so that the element of road barrier opposes a gradual resistance to the impacts. All this with the objective to absorb, in the least traumatic way, the kinetic energy of a vehicle that impacts it.
  • FIG 1 perceive as an element of road barrier (10), according to the invention, that understands a ribbed system cover (3); it is strengthened by members of reinforcement (4r) and it is connected through bolts (5q) to the uppercuts (1m), provided of ribs of stiffening(2c).
  • the posts (1m) are anchored to the foot on the ground (t), through of the bolts of anchorage (6), that are introduced in hollow (7) of the ground sprinkled of synthetic resin (14).
  • the system of anchorage will be explained in particular in the succession of the description).
  • This rib is positioned among the cover ( 3) and is destined to increase the resistance to flection of same post : the profile of such rib has a concave zone (z), in correspondence of which, in absence of strains, the cover (3) doesn't lean on stiffening rib (2c).
  • the cover (3) touches the rib (for an important portion of its vertical development), only after having suffered a preset deformation caused by the transversal component of an impact: consequently the resistance to the impact, offered by the posts (1m), results gradual in dependent way from the sizing of the parts. It is obvious that it is, worthwhile, to mechanically connect among them the rib cover (3) of adjacent two elements of road barrier so that to leave again in a certain measure the agent parallel strengths to them.
  • a bolt of anchorage (6) have the head (6t) drowned in a hollow (7) of the ground (T).
  • the head of the bolt is shaped and it is sprinkled with a synthetic resin (14).
  • the threading extremity of the bolt(6f) sticks out from the ground (t).
  • This extremity cross an element (8) that it has a form of bell.
  • the element has a preset deformability for bending and/or smashing.
  • a die is tightened (9), on the filleted extremity (6f) and it presses against the element (8).
  • the element (8) presses against an horizontal wall that constitutes the surface of support (11) of the post(1m) on the ground (t). In this manner every part of anchorage introduces a preset resistance to solicitations.
  • an road barrier (10) that has a diversified resistance to the solicitations deriving from an impact. This provokes the smallest possible damage to the occupants of a motor vehicle in case of collision.
