Definitions

  • Each span or section of the barrier is composed of two road-embedded supports (or of one embedded) and -a plurality of intermediate non-embedded supports resting on the pavement.
  • the horizontal beams made of reinforced and massive concrete .are provided with annularly shaped terminals which slide around two adjoining supports. Washer-like doughnuts may :be inserted between superimposed beams to obtain a rail effect.
  • the annular extremities and the doughnut separators are movable (pivotable) about the vertical supports to impart the required elastic effect.
  • the present invention relates to road barriers and road dividers of unique construction; specifically, to road dividers which have pivotable span joints of prefabricated reinforced massive concrete.
  • the known barriers which are visible along the highways or which are used las dividers between lanes of opposite traffic are generally formed of metal sheets, aesthetically shaped, lined p in ya continuous row and supported lat given intervals 'by poles or stakes solidly anchored n the pavement or in the ground.
  • the horizontal elements of the barrier lare pivotably inserted on pilasters or stakes, so as to obtain a movable joint thereabout. Since intermediate every two :sequentially fixed or embedded supports there is a plurality of non-embedded similar vertical supports, fthe movement of the pivotable horizontal elements about their terminal supporters allows the absorption of vehicular impacts with a gradwal resilient effect.
  • This effect coupled with the height of the road divider, prevents, as it can be readily seen, the jumping of a vehicle yacross the divider and in-to a lane of incoming traic or, yas the case may be, the leaving o-f the road due to loss of control of the steering mechanism of the vehicle.
  • FIGURE 1 is a side view of a series of elements (spans) in the road barrier or divider;
  • FIGURE 2 shows in cross-section two adjoining spans, taken :along the direction A-A of FIGURE 3;
  • FIGURE 3 is a top view of the lbarrrier of FIGURE 1;
  • FIGURE 4 shows partially in cross-section an embedded terminal of the barrier
  • FIGURE 5 shows in cross-section #a terminal of the barrier :along the direction B-IB of ⁇ FIGURE 2.
  • the road 'barrier or divider of the invention is composed of a plurality of elements or beams 1, 2, prefabricated of reinforced concrete which 'has been treated vibrationially to impart a substantially void-free structure.
  • the barrier furthermore, comprises fixed supports or stakes F, which are also made of the same material of construction. These supports F are installed at regular, predetermined intervals along the highway. Each support F is provided with a lower base 5 for )anchoring into .the ground #and with a vertical cylindrical spindle 6 of diameter preferably smaller than the internal diameter of the openings 4 of elements or beams 1, 2.
  • the barrier also includes additional supports G for location intermediate the supports F and having structural characteristics similar to those of the fixed supports F, with the exception that the base or foot "7 of supports G is not intended to be embedded in the ground, but to simply rest on the surface thereof.
  • Elements or beams 1, 2 are mounted and assembled on and between the supports F and the intermediate supports G, so that the cylindrical portions 6 and 8, respectively, are p-assed through the openings 4 of the terminals 3 of elements 1, 2.
  • the number of non-ernbedded vertical support-s G may vary Ibetween any two iixed supports F; so can Athe height of lthe barrier land means of separating dis'cs 9 - ⁇ 6 land 8, las shown in the 1, 2 may be vertically sepa the number of interposed discs 9. All of these variantsV permit a great ⁇ flexibility of construction without varying -tlhe shape, size or fabrication of the various elements of the barrier.
  • Road lbarrier of prefabricated reinforced concrete which comprises a plurality of horizontal elements vhaving annularly ⁇ shaped extremities; :a first plurality of vertical supports having la substantially cylindrical upper portion inserted in apertures in said extremities and a larger lower base portion imbedded in the ground; a second .plurality of vertical supports similar to said first plurality of vertical supports ⁇ but 'having :a ⁇ shorter base portion resting ton the surface of the ground; said upper portions of the supports having a diameter smaller th-an the inner diameter of said annularly shaped extremities whereby the Ihorizontal elements are hinged connected to the supports and the second said support-s may move relatively to the ground on vehicle impact.
