  • the present invention relates to barriers, in particular to the type of barriers found on roads, in particular motorways.
  • Crash barriers are known and are routinely used to prevent vehicles leaving a road in the event of an accident or loss of control. They are typically found at the side of a road and between each side of a multi-lane highway, such as a motorway. It is known to provide permanent crash barriers and also temporary crash barriers, which can be used to temporarily split a multi-lane highway into different lane configurations.
  • crash barriers presents numerous obstacles and these are often the result of the size and weight of crash barriers which, by their very nature, are usually made from heavy components such as metal stakes and panels.
  • a crash barrier In designing a crash barrier, not only must the barrier perform its primary function of preventing a vehicle from leaving the road, but it must also do so safely. Further, in the event of damage, it is often time consuming to repair a stretch of crash barrier because the component parts are heavy and must be replaced. For example, a series of multiple crash barriers are usually provided and individual barriers must be replaced when damaged. This often involves the use of heavy machinery to lift damaged sections and then insert new sections.

  • the barrier of the present invention provides significant advantages over known barriers.
  • the provision of removable side panels means that, in the event of a crash, it is likely that only the side panel will be damaged. In view of the removable nature of the side panel, there is no need to replace the entire length of barrier; rather, the panel can simply be replaced.
  • the barrier can initially be provided in a "light-weight" form during installation and then, if required, the weight of the barrier can be increased by filling the cavity, for example with ballast.
  • the cavity can be filled with an energy absorbing material, such as high density foam, for providing a cushioning effect in the event of an impact.
  • an energy absorbing material such as high density foam
  • the provision of the cavity protects the central member from damage, reducing the likelihood of the entire length of barrier requiring replacement.
  • each of the outer side panels is positionable in two or more positions relative to the central member, wherein each of the positions forms a different sized cavity between the outer side panel and the central member.
  • the central member comprises first and second central panels removably connected together, wherein the first central panel forms a first half of the central member and the second central panel forms a second half of the central member.
  • a first outer side panel is connected to the first central panel and a second outer side panel is connected to the second central panel.
  • the outer side panels are removably connected to the central member of the barrier.
  • the outer side panels are removably connected to the central member of the barrier by one or more connectors.
  • the one or more connectors comprise one or more bolts.
  • the barrier comprises first and second outer removable side panels on opposing sides of the longitudinal length of the central member.
  • the central member is substantially I-shaped comprising horizontal members connected by a vertical upright.
  • each outer side panel is shaped such that it is positionable between the horizontal members of the central member with a cavity formed between the outer side panel and the vertical upright.
  • the outer side panels comprise a vertical member and horizontal upper and lower members connected to the upper and lower ends of the vertical member, said upper and lower side members comprising connectors for connecting the outer side panels to the central member.
  • the upper and lower members are positioned relative to the vertical member such that, when the outer side panel is positioned in a first orientation, a cavity of a first size is formed between the outer side panel and the central member and, when the outer side panel is positioned in a second orientation, a cavity of a second size is formed between the outer side panel and the central member.
  • the upper and lower members protrude from one side of the vertical member, preferably at a right angle thereto.
  • the outer side panels comprise a right angled C-shape or U-shape.
  • the outer side panels are of a different deformability than the central member.
  • the outer side panels are more easily deformed than the central member.

  • the barrier comprises a filling contained within one or more of said cavities.
  • the filling comprises ballast and/or a deformable material.
  • the filling comprises a high density foam.
  • the filling comprises sand, stone and/or water.
  • ballast is particularly advantageous for applications in which it is not possible to anchor the barrier to a road surface in the usual way. For example, this would particularly be the case for a barrier used on bridges when normal anchoring by drilling the surface is not permitted and thus lengths of barrier might depend upon their dead-weight for their stability and anti- deflection.
  • the barrier comprises an outer protective layer over at least a part of its outer surface.
  • the outer protective layer is for minimising external damage to vehicles and drivers in the event of an impact, in particular motorcycles and small cars.

  • At least one, preferably both, of the outer side panels comprises one or more access holes for permitting access to the central member and the cavity formed between the outer side panel and the central member.
  • the barrier comprises a cross member at or near an open end of the barrier. This is particularly advantageous because it allows the barrier to be pulled out of a container or lorry and, thus, greatly eases unloading and installation of the barrier.
  • the cross member comprises a bar positioned between the side walls of the central member.
  • the central member comprises one or more cavities for receiving a joining member.
  • the provision of a cavity for receiving a joining member means that the barrier can be provided without a joining member positioned in situ. This reduces the weight of the barrier and thus improves handling thereof.
  • a joining member can be inserted into the cavities of adjacent barriers to connect the barriers together.
  • the central member comprises an upper cavity and/or a lower cavity for receiving a joining member.
  • the outer side panels are removably connected to the central member of the barrier by one or more connectors, wherein the connectors also secure a joining member in position within one or more cavities of the barrier, preferably of the central member.
