Definitions

  • This invention concerns a metallic safety barrier especially suitable for bridges and viaducts and of the type disclosed in EP-A-0428097.
  • the invention concerns a barrier structurally suitable to meet the strictest safety standards and having at the same time weight characteristics compatible with the usual type of beam employed for roadway constructions, particularly at bridges and viaducts.
  • the barrier of the invention can be employed on bridges and viaducts as a central traffic dividing strip or as a rigid lateral edge but can also be used in any other employment requiring safety means having a low weight and a great retaining capability.
  • the state of the art includes several apparatuses intended to improve driving safety on modern roads and motorways. Amongst these apparatuses a role of primary importance is played by the so-called guardrails.
  • guardrails have to enable the following objectives to be attained:
  • the barriers are permitted to undergo deformations and residual displacements which enable the decelerations induced in the motor vehicle to be reduced to a minimum, thus achieving acceptable rebound trajectories together with minimum damage.
  • guardrails made of steel strip are employed on bridges and viaducts and entail the well known limits made still more evident by the absolute need to prevent motor vehicles leaving their carriageway at the above parts of the roads.
  • EP-A-0428097 discloses a safety barrier consisting of a modular metallic element which can be connected to equal elements arranged next to it; this element has sidewalls, in one or more reciprocally connected elements, and frontal walls.
  • This element is substantially hollow within and comprises lengthwise stiffening means and means for connection to adjacent elements, together with means for fixture to the ground.
  • EP-A-0428097 teaches the obtaining of a metallic barrier which, so as to achieve the required capacity of absorption and structural stability, requires weights and components that impair the barrier in terms of weight and rigidity and therefore have an unfavourable effect on the frameworks and on drivers in the event of an accident.
  • the purpose of this invention is to provide a metallic safety barrier which is lighter, but stronger and safer, than that disclosed in EP-A-0428097.
  • a further purpose of this invention is to provide a quick and safe system to connect together the adjacent metallic elements composing the barrier.
  • the barrier according to the invention consists of modular metallic elements which can be coupled to equal adjacent elements to form the safety barrier.
  • Each of these modular elements consists substantially of a frontal metallic absorption panel which is stiffened lengthwise and crosswise by at least one reinforcing element.
  • the frontal absorption panel has a known profile of the New Jersey type, which is formed as a double trapezium becoming larger towards its bottom and includes in its lower half a change of inclination to enlarge the supporting base of the modular element and to act in a differentiated manner against the tyres of a motor vehicle.
  • the frontal absorption panel according to the invention is bent advantageously backwards at its lower end along its supporting base and for a portion of the same.
  • the modular elements are open at their rear so as to be lighter.
  • the barrier according to the invention weighs about 120 to 140 kgs. per linear metre as against the 800 to 1100 kgs. per linear metre of the normal New Jersey type concrete barriers and against the 160 kgs. per linear metre of the barriers according to EP-A-0428097.
  • the modular elements of the barrier according to the invention include at their upper end supporting means with which there cooperates at least one suitable lengthwise bar to provide further retention.
  • This lengthwise retention bar has the purpose of further stiffening and reinforcing the safety barrier in the lengthwise and vertical directions and plays a special part in retaining a motor vehicle on its own carriageway so as to prevent the motor vehicle climbing over the safety barrier.
  • two or more lengthwise retention bars are included.
  • the frontal absorption panel contains within its upper part a stiffening bracket to distribute the loads so as to distribute better the stresses which the retention bar imparts to the absorption panel at the time of an impact.
  • the points of connection of one retention bar to another are displaced advantageously away from the connecting ends of adjacent modular elements composing the safety barrier.
  • the remaining metallic structure of the barrier according to the invention has been devised to make possible an improved safety performance, particularly as regards absorption of kinetic energy, by converting that energy at the moment of impact into a greater action of deformation of the structure thus hit.
  • this better structure includes improved stiffening ribs, or reinforcing uprights, and new lengthwise reinforcing elements; furthermore, the structure is fixed advantageously with specific anchorage bolts.
  • the supporting means with which the retention bar cooperates are positioned in correspondence with the stiffening ribs, and in this case the stiffening brackets which distribute the loads are eliminated.
  • the barrier according to the invention gives excellent results in retaining a motor vehicle weighing thirty tonnes hurled at a speed of 65 kms. per hour at an angle of incidence of 30°.
  • the zone of plastic deformation is restricted substantially to the neighbourhood of the point of impact of the motor vehicle against the safety barrier.
  • a covering panel secured, for instance, by rivets or other means may be fixed to the rear outer face of the frontal absorption panels for mere aesthetic and non-structural reasons.
  • the modular metallic element includes in its lower front portion a connecting shoe in the event that the safety barrier is fixed to a slab raised above the roadbed.
  • the modular metallic elements according to the invention are butt-jointed together with a reciprocal connection at their ends by means of suitable connecting means so as to form a barrier without any break of continuity.
  • the connecting means consist of a horizontal plate fitted to the upper end of the frontal absorption panels and firmly secured, by bolts and nuts for instance, to the two modular metallic elements to be connected.
  • the means which connect the modular metallic elements consist of a double hinge, the eyelets of which are solidly fixed to the terminal reinforcing uprights.
  • a connecting plate with mating connecting eyelets cooperates with those eyelets.
  • the installation and successive connection of adjacent modular metallic elements equipped according to this variant are carried out by positioning the connecting plate between two adjacent modular metallic elements with its eyelets on the same axis as the eyelets on those two adjacent modular metallic elements and threading therethrough from above two pins which cooperate with the relative eyelets.
  • the double hinge extends only partly, advantageously along the upper part of the modular metallic elements.
  • the modular metallic elements according to the invention may also include specific hooks for connection to preexisting modular metallic elements of another type.
  • Each modular metallic element comprises means for anchorage to the ground; these anchorage means are advantageously of a resilient type pre-loaded to provide a required resilient resistance to the stresses resulting from the impact of a motor vehicle.
  • the means for anchorage of the modular metallic elements to the ground consist of a plurality of anchorage bolts which cooperate with appropriate seatings machined in the lower part of the modular metallic elements and which are anchored in the slab of the carriageway. These seatings cooperate directly with the structural elements providing vertical stiffening and consisting of stiffening ribs or uprights.
  • the anchorage means consist of anchorage bolts cooperating with tubes or sheaths secured firmly to the inside of the metallic structure of which the bridge consists.
  • the stiffening ribs which are at least two for each modular metallic element, are connected solidly to the inner surface of the frontal absorption panel so as to form one single body.
  • the lengthwise reinforcing element which is suitably shaped, for instance, substantially as a "V" with its broad sides anchored firmly to the back of the frontal absorption panel, is substantially as long as the modular metallic element and is positioned at a height between 0.3 and 0.6 times, substantially 0.45 times, the height of the frontal absorption panel of the metallic barrier according to the invention.
  • the lengthwise reinforcing element consists of an inner "V-shaped” bent element, or advantageously a dovetail-shaped element, formed in the frontal absorption panel.
  • vertical spaced connecting bridges may be included in correspondence with the horizontal lips of the inner bend.
  • two or more lengthwise reinforcing elements cooperate with the frontal absorption panel.
  • the upper of the two is positioned at a height from the ground between 0.3 and 0.6 times, advantageously 0.45 times, the height of the frontal absorption panel, whereas the lower of the two cooperates advantageously by means of one of its sides with the vertex of the change of inclination of the frontal absorption panel.
  • the stiffening ribs have an L-shaped cross-section, the long side of which has a variable length so as to be adapted to the conformation of the frontal absorption panel.
  • the long side of the "L" has an increasing development in a downward direction so as to be anchored with its free end to the rear surface of the frontal absorption panel to which it is firmly secured.
  • the orientation of the rear, vertically positioned, short side of the stiffening ribs is turned away from the side of the arrival of vehicles passing by.
  • Substantially V-shaped grooves are machined in the long side of the stiffening ribs in a number corresponding to the number of lengthwise reinforcing elements; these grooves enable the lengthwise reinforcing elements to pass and be positioned against the rear surface of the frontal absorption panel.
  • the stiffening ribs are bent at their lower end to form a supporting base which cooperates terminally with the advantageously bent lower edge of the frontal absorption panel.
  • Fig.1 is a diagram of a safety barrier 10 consisting of a plurality of modular metallic elements 11 positioned adjacent to each other and connected together; the modular metallic elements 11 include means 30 for their fixture to the ground 28.
  • the frontal conformation of the modular metallic elements 11 is like that of the New Jersey type and comprises the well-tried advantageous features of the same.
  • the modular metallic element 11 includes a shaped frontal absorption panel 12, which has in its lower part a vertex 32 coinciding with a change of the inclination of the frontal absorption panel 12.
  • the frontal absorption panel 12 includes two reinforcing elements 13a,b arranged lengthwise along its rear surface and having substantially the same length as the modular metallic element 11.
  • the first lower reinforcing element 13a is fitted with one side in the vicinity of the vertex 32 of the change of inclination of the frontal absorption panel 12 and extends downwards, whereas the second higher lengthwise reinforcing element 13b is located at a height from the ground 28 between 0.3 and 0.6 times, advantageously 0.45 times, the height of the frontal absorption panel 12 of the metallic barrier 10 according to the invention.
  • the frontal absorption panel 12 comprises only one reinforcing element 13b, which is arranged along the rear of the panel 12 and has substantially the same length as the modular metallic element 11.
  • the reinforcing element 13b is obtained with an internal V-shaped bend of the frontal absorption panel (Fig.12) or with an internal dovetailled bend of the frontal absorption panel (Fig.11).
  • the frontal absorption panel 12 includes a plurality of substantially vertical stiffening ribs 14, which are at least two in number on each modular metallic element 11 and are spaced regularly apart and secured to the frontal absorption panel 12 and to the reinforcing elements 13.
  • each modular metallic element 11 includes six stiffening ribs 14.
  • the stiffening ribs 14 have an L-shaped cross-section along a horizontal plane (Fig.7); the long side 14a of the "L” has a variable length which mates with the profile of the frontal absorption panel 12 to which the ribs 14 are firmly secured.

  • the supports 15 are bent forwards so as to place the retention bar 16 in cooperation with the projection of the almost vertical upper surface of the frontal absorption panel 12.
  • the frontal absorption panel 12 includes within its upper portion a V-shaped stiffening and stress-distribution bracket 17, which has the purpose of containing and distributing the stresses caused by the retention bar 16 on the frontal absorption panel 12 at the moment of impact of a motor vehicle.
  • the supports 15 are positioned in correspondence with the vertical stiffening ribs 14, and in this case the stiffening and stress-distribution brackets 17 are omitted.
  • the supports 15 are positioned at least in correspondence with the end stiffening ribs 14 and act also as an attachment means 20.
