Definitions

  • the present invention concerns a safety barrier intended to be installed longitudinally along the edges of a roadway.
  • the present invention relates to barriers used on structures such as bridges, viaducts and supporting walls, and which must therefore combine the mechanical properties described above with a low weight which is compatible with the severely limited loads supportable by such structures.
  • the object of the present invention is to provide a security barrier which, as well as satisfying the requirements mentioned above, is easy and safe to assemble.
  • this object is achieved by a safety barrier and an associated method of production having the characteristics specifically referred to in the following claims.
  • the safety barrier according to the invention is characterised by the presence of support structures in the form of ground anchors for fixing to an underlying ground beam, which support structures are capable of plastic deformation and of enabling the plastic deformation of the ground anchors as the result of the forces to which they are subjected upon collision of a vehicle with the barrier.
  • support structures in the form of ground anchors for fixing to an underlying ground beam, which support structures are capable of plastic deformation and of enabling the plastic deformation of the ground anchors as the result of the forces to which they are subjected upon collision of a vehicle with the barrier.
  • these support structures have selective connection means for connecting to the other components of the barrier, such that they can be removed or their positions changed during installation.
  • the installation of the barrier may thus involve the initial formation of a continuous outer lateral wall which provides effective protection for those responsible for the subsequent operations such as anchoring and assembling the inner wall.
  • Figure 1 is an exploded perspective view of a portion of a road barrier according to the invention.
  • Figure 2 is a side view of the barrier of the invention in the assembled condition
  • Figure 3 is a plan view in section taken on the line III- III of Figure 2;
  • Figure 4 is a sectional view taken on the line IV-IV of Figure 3;
  • Figure 5 is a view similar to that of Figure 4, showing the possible deformation to which the components of the barrier are subjected upon collision of a motor vehicle;
  • Figure 6 is a plan view of a portion of a retaining bar of the barrier according to the invention.
  • Figure 7 is a plan view of a further portion of the retaining bar of the barrier according to the invention.
  • FIG 8 is a sectional view taken on the line VIII-VIII of Figure 7.
  • a security barrier intended to be positioned longitudinally along the edge of a roadway, includes (Figure 1) an inner lateral wall 10 intended to face the carriageway, and an outer lateral wall 12 intended to face away from the carriageway. These lateral walls together define a cavity 14.
  • Both the inner and outer walls 10, 12 are formed from a series of sheets 16 joined together in series using conventional methods such as bolting, riveting and the like, and which are not shown in detail.
  • the connection zones of the sheets 16 forming the outer wall 12 are longitudinally offset with respect to those of the sheets forming the inner wall 10, thus increasing the cohesion of the barrier.
  • the inner wall 10 is preferably shaped with the well-known "New Jersey" shape.
  • longitudinally-spaced reinforcing posts 20 which project transversely into the cavity 14 are fixed to the sheets 16 forming the lateral walls 10, 12.
  • the posts 20 have a C- section with two opposite transverse ribs 22 supporting a longitudinal reinforcing girder 24.
  • the posts 20 also have a base plate 26 with which are associated barrier-anchorage means, as will be described in more detail below.
  • this latter includes a retaining bar 28 which extends longitudinally above the lateral walls 10, 12 to which it is connected by longitudinally-spaced supports 30.
  • the bar 28 is formed from several tubular elements arranged in series. The junction between two consecutive elements and intermediate portions of the various elements are surrounded by associated tubular sleeves 32 which are open along a generatrix 34 ( Figures 6, 7 and 8) . The edges of each sleeve 32 along the open generatrix 34 are extended as respective facing flanges 36 provided with locking means .
  • bolts 38 each having a nut and a screw capable of passing through axial holes 40 in the flanges 36.
  • Each sleeve 32 attached ( Figures 7 and 8) at the junction between two consecutive elements has, disposed symmetrically in relation to the centre of the junction, first and second pairs of diametrically-opposed holes 42 capable of enabling an associated screw 44 to pass through. This screw passes through corresponding holes 46 formed through the end of the associated bar element 28 and can be locked with a nut 48.
  • the barrier has means for anchoring it to the ground or to a fixed underlying structure, in particular, a ground beam 50 ( Figures 3 and 4) .
  • each ground anchor 52 includes a nut 58 capable of being screwed to the upper end of the rod 54, a washer 60 from the base of which projects a sleeve 62, and a tubular sheath 64 which surrounds the lower end of the rod 54.
  • Each ground anchor 52 is supported by an associated support structure 66 which has a cavity 68 for the rod 54 to pass through, and is positioned between the facing ribs 22 of an associated post 20 and over its base plate 26.
  • the support structure 66 is box-like and includes an apertured prism 70 having a quadrilateral base, the sides of which substantially parallel to the lateral walls 10, 12 are fixed to the middle portion of associated sections 72, these also extending substantially parallel to the lateral walls 10, 12.
  • Each section 72 is formed from a first, substantially vertical limb 74 to which one side of the prism 70 is fixed, and a second, substantially horizontal limb 76 intended to rest on the base plate 26.
  • the limbs 74, 76 are joined together by a curved intermediate portion 78 of the section 72.
  • the walls of the inner cavity 68 are spaced from the upper portion of the rod 54 adjacent the portion which can pass through the aperture 56 formed in the base plate 26.
  • the upper portion of the rod 54 passes through the sleeve 62 disposed within the hole 84 of the prism 70, and projects above the washer 60 to enable the nut 58 to screw thereto.
  • transverse plates 80 provided with holes 82 through which pass bolts (for greater clarity, these are not illustrated in the drawings) for fixing to the ribs 22 of the post 20.
  • the outer wall 12 thus constitutes a continuous parapet which functions to protect those persons involved in the subsequent phases of the installation, while the support structures 66 constitute a precise reference for the formation of anchorage holes 86 in the ground beam 50 ( Figures 3 and 4) into which the lower ends of the rods 54 of the ground anchors 52 are to be inserted.
  • the tip of the boring tool is made to pass through the hole 84 of the prism 70 of a support structure 66 (as well as through the aperture 56 formed in the base plate 26) , and is thus guided with precision.
  • the various support structures 66 are then removed by unscrewing the associated bolts, not shown, which fix the plates 80 to the ribs 22. It is thus possible to form a second series of anchorage holes 88 in the ground beam 50, which constitute a widening of the upper portion of the first anchorage holes 86 so that they are offset with respect to these latter. In this case, the tip of the boring tool is made to pass through the apertures 56, and uses the previously- formed first anchorage holes 86 as a reference.
  • each of the support structures 66 is returned to its original position ( Figure 3 and 4) and installation continues with the insertion of the associated rod 54 of the ground anchor 52 into the cavity 68 and the anchorage holes 86, 88, and location of the sleeve 62 associated with the washer 60 within the hole 84 of the prism 70.
  • the retaining bar 28 is formed from various elements locked in the sleeves 32 by the bolts 38 which act on the flanges 36.
  • the sleeves 32 ( Figures 7 and 8) located at the junction of two consecutive elements of the bar 28 have first and second pairs of diametrically-opposed holes 42 capable of enabling an associated screw 44 to pass through, which passes through corresponding holes 46 formed in the associated ends of the elements and is locked with an associated nut 48. In this way, the continuity and the strength of the bar is assured, even at the junctions.
  • junctions corresponds with an expansion joint, it is of course possible to provide a looser coupling, leaving sufficient space between the facing ends of the elements and utilising a sleeve without flanges 36 and the associated lock bolts 38.
  • This structure of the retaining bar 28 enables it effectively to resist vehicles colliding with the barrier overturning while, at the same time, dissipating the energy.
  • the conformation according to the invention of the anchorage means to the ground beam 50 enables a significant absorption of kinetic energy, considerably reducing the risk to which the vehicle occupants are exposed.
  • the rod 54 undergoes a progressive plastic deformation ( Figure 5) which enables a significant absorption of energy before it eventually breaks. Further energy is also absorbed by the deformation of the support structure 66.
  • Figure 5 can also be in the form of other embodiments, not illustrated, to obtain a comparable result.
  • the sections 72 which support the prism 70 can be L-shaped, C-shaped, with an uneven outline, or they can be replaced by rectangular tubes, round tubes or half tubes.
  • the support structure 66 may be realised in several stages of differentiated deformability, or in monoblock form.
  • the support structure 66 may be provided with any kind of selective connection means for connecting to the other barrier components such that it can be removed or its position altered during the installation of the barrier. Equally, the support structure 66 may simply rest against the base plate 26 and be held in position by the traction exerted by the ground anchor 52.
