Abstract
A central road safety barrier includes modules mutually couplable by means of a bolt which engages holes made in protrusions extending in a longitudinal direction at the ends of the modules. Walls adjacent to the protrusions improve the transfer between the modules of an impact of an errant vehicle on the barrier and improve response to an impact. The safety barrier provides an emergency openable passage. A module may include a wall solidly constrained to an upright and adjacent to the protrusions of the module on a first side of the barrier. An openable passage module has a further wall solidly constrained to a further upright and adjacent to the protrusions of the openable passage module on a second side of the barrier.
Claims19
A module of road safety barrier for contacting and redirecting an errant vehicle on both a first side and a second side opposite one another, comprising:
- a first longitudinal beam;
- a second longitudinal beam;
- an upright and a further upright that support the first beam and the second beam, at respective opposite longitudinal ends of the module;
- protrusions at both longitudinal ends of the module, each extending in a longitudinal direction and comprising a hole, the protrusions and the holes being configured so as to house a bolt which couples another module,
- the module being characterised in that:
- the module comprises a wall which is solidly constrained to the upright and which is adjacent, on a second side of the module, to the protrusions;
- the module comprises a further wall which is solidly constrained to the further upright and which is adjacent, on a first side of the module, to the protrusions;
- each protrusion at the longitudinal end of the further upright extends transversally towards the second side in such a way that the edge thereof facing towards the second side is substantially aligned to the inner face of the wall;
- each protrusion at the longitudinal end of the upright extends transversally towards the first side in such a way that the edge thereof facing towards the first side is substantially aligned with the inner face of the further wall.
A road safety barrier for contacting and redirecting an errant vehicle on both a first side and a second side of the barrier opposite one another, and comprising:
- modules which each comprise a first beam, a second beam and uprights which support the first beam and the second beam, the modules being configured in such a way that the first beams and the second beams are at the same heights from the ground;
- a bolt configured to connect, in a coupling condition, an upright which is located at a longitudinal end of a module and which is configured to be fixed to the ground and a further upright which is located at a longitudinal end of a further module;
- wherein both the module and the further module, at a respective longitudinal end, comprise protrusions, each extending in a longitudinal direction and comprising a hole, the protrusions and the holes being configured so as to house the bolt in the coupling condition,
- the barrier being characterised in that:
- the module comprises a wall which is solidly constrained to the upright and which is adjacent to the protrusions of the module on a first side of the barrier;
- the further module comprises a further wall which is solidly constrained to the further upright and which is adjacent to the protrusions of the further module on a second side of the barrier;
- wherein the module and the further module are configured in such a way that in the coupling condition the wall is adjacent to the protrusions of the further module and the further wall is adjacent to the protrusions of the module in order to offload onto the adjacent module a part of the energy absorbed in the impact of an errant vehicle.
