Definitions

  • This invention refers to a road safety barrier which automatically retracts to obtain central connection gaps between road and/or motorway lanes.
  • this invention refers to a safety barrier with a structure that allows it to be rapidly retracted to allow the transit of vehicles from one lane to another during road and/or motorway maintenance work.
  • barriers can consist of sections sliding on supports that can be fixed in appropriate housings in the ground.
  • the overall longitudinal extension of the sliding sections can be up to 16 metres, with the supports, aligned as much as possible, positioned at a distance of around 1.5 metres apart.
  • Their opening foresees the sliding of the sections to open a central gap followed by the temporary removal of around 20 supports from their respective housings and their loading on a motor vehicle for transport to a place relatively far away from the mobile barrier so that road maintenance work can be carried out in the vicinity of the barrier.
  • a further type of mobile barrier consists of impact- resistant rigid plastic containers filled with antifreeze liquid, connected to each other by means of steel bars. These bars must be reciprocally constrained in order to form a compact framework resistant to impact and at the same time presenting appropriate deformability to absorb any impact. To ensure this traction must also be applied to the steel barriers by connecting them to appropriate tighteners positioned at the longitudinal extremities of the gap. To open this mobile barrier, the containers must be emptied and the tension of the bars must be reduced. The steel bars must then be separated and the containers, which may be around 15 in number, each with an approximate volume of one cubic metre, must be loaded onto a motor vehicle and carried away.
  • a further drawback is represented by the fact that the operations to remove the mobile barriers in order to open the gap take around three hours to carry out, and during this period the vehicles in transit on the motorway or highway concerned are subjected to temporary halts or considerable slowing down to allow the work to be done.
  • the aim of this invention is to provide a road safety barrier which automatically retracts to obtain central connecting gaps between road and/or motorway lanes, capable of eliminating or significantly reducing the drawbacks described above.
  • This invention also aims to provide an automatically retractable road safety barrier that can be fitted to any gap requiring the minimum amount of space due solely to its actual presence in the working position.
  • the framework in the rest position, retracted and contained inside the chamber, fills the chamber with its upper part flush with the road surface in order to ensure continuity with the surface.
  • the framework comprises mutually cooperating reinforcement elements, in particular when the barrier is completely contained in the respective chamber, in order to ensure adequate mechanical resistance to the loads of the vehicles passing through the gap without undergoing appreciable deformation.
  • the surface of the framework can be treated with anticorrosion agents, for example it can be galvanised, and the part which is on view in the rest position can have a high degree of surface roughness in order to prevent slipping of the tyres of the vehicles passing over it.
  • the retractable barrier is fitted with a grid over the access to the chamber.
  • the chamber is appropriately dimensioned to contain not only the framework but also any small grained impurities that may fall through the grid.
  • the base of the chamber is also equipped with drainage channels for the disposal of groundwater.
  • the means of support of the framework can be equipped with appropriately tensioned cables and means of elastic loading to absorb and support any vehicle impact.
  • figure 1 shows a cross-section side view of a road barrier according to the invention, in the working position, with the central part excluded;
  • figure 2 shows an enlarged front view of the barrier in figure 1 ;
  • figure 3 shows a similar view that of to figure 1, with the barrier in the rest position;
  • figure 4 shows a similar view to that of figure 2, with the barrier in the rest position.
  • the reference number 10 generally indicates a road safety barrier, in the case in question a barrier that automatically retracts to obtain central connecting gaps between road and/or motorway lanes.
  • the barrier 10 comprises a framework 11 consisting of at least one crosspiece or rail 12 hinged at its ends to uprights or bars 13 each of which is hinged at the opposite end to the ground 14.
  • the fork-shaped coupling 19 is fitted with holes in which a pin 22 is inserted and which also goes through the relative hole 23 in the respective upright 13.
  • a pair of tongues 24 is inserted between the fork-shaped coupling 19 and the respective upright 13 in order to stiffen the upright 13 in the erect position.
  • Each coupling 19 is fixed to the base of a chamber 25 designed to house the framework 11 retracted in the rest position (figure 3).
  • the chamber 25 presents an access opening 26, immediately below the framework 11, covered by a special closing grid 27 fixed to the uprights 13. In the working position, the grid 27 is flush with the road surface (figure 2), while in the rest position it is housed on the bottom of the chamber 25.
  • the grid 27 may consist of a 25 millimetre mesh and may be covered by strips of rubber (not shown in the drawings) larger than those of the opening 26 in order to prevent snow from entering the chamber 25.
  • the dimensions of the bottom of the chamber 25 may in any case be sufficient to contain not only the framework 11 in the rest position, but also any small sized particles that may fall in through the meshes of the grid 27.
  • the bottom of the chamber 25 may also be equipped with drainage channels for the disposal of groundwater.
  • the control device 33 is hydraulically connected to any of the linear actuators 29 and 31 which, receiving pressurised oil, permit the protrusion of the respective shafts 28 and 30.
  • Both the rail 12 and the section 16, at their longitudinal end opposite to the end fixed respectively to the shafts 28 and 30, are fixed to steel cables 35 the other ends of which are attached to a fixed frame 36.
