Definitions

  • the invention relates to the construction of road safety systems, in particular of side barriers arranged along the roads to retain vehicles within the carriageway in the event of accidents.
  • Side safety barriers are installed along roads of various type and category to keep vehicles within the carriageway in the event of accident.
  • Side protection barriers also commonly named guardrails, must be certified in order to be installed along roads. In Europe, such certification is the CE marking.
  • a road safety barrier In order to obtain the latter, a road safety barrier must have some minimum requirements, among which there are: passing crash tests according to EN1317-1 /2 relative to the type of crash and involved vehicles, assembly performed according to the executive drawings of the elements constituting the protective barrier and production of the device according to a detailed production and control plan.
  • the support material in real cases even when it is different from the soil, has a different consistency with respect to the deeper layer of ground on which the road is built.
  • the most common operations consist in: modifying the configuration of the ground, which is replaced by material having higher mechanical properties, elongating the barrier poles in part embedded in the ground and/or increasing the contrast surface of the pole.
  • an anchoring device to the non- superficial layers of the road paving for a safety road barrier supporting pole having its own longitudinal direction
  • the device comprises a coupling element, adapted to be fixed at a predetermined height between base and top of said supporting pole when it is driven into a ground near a road, at last one rigid elongated element having a first proximal portion fixed to the coupling element and a second distal portion, with a surface provided with surface protrusions or with an increased friction roughness surface, adapted to be either immersed or driven under a road paving, in a direction either transversal or orthogonal to the longitudinal direction of the safety road barrier.
  • the initial construction costs are greatly reduced, due to the simplicity of the device and to the limited number of elements which form it, and so are the installation costs, due to its simplicity.
  • the installation procedure of the ground anchoring device of the invention can be performed with machines which are very common and could be easily performed manually, whereby reducing costs while guaranteeing a high degree of safety of the barrier which has supporting poles anchored with the device of the invention.
  • the anchoring device can be easily installed on a safety barrier both during the first construction or renovation of a road or when it is necessary to reinforce pre-existing safety barriers along stretches of road which may be located on land of low consistency, guaranteeing in all cases a considerable increase in the retaining capability of vehicles, in particular in incidents in which a very high force component is released transversely onto the safety barrier, i.e. in particular in those cases in which the vehicle crashes are very close to the angular values of 90 ° with respect to the direction of the safety barrier.
  • the present invention allows to transfer onto the road the same ideal installation conditions obtained in tests without necessarily having to resort to the costly and disruptive operations described above (increase of the resistant surface of the pole/ground system and/or redevelopment of the road margin).
  • the anchoring device of the invention allows a coupling to the non-superficial layers of the road paving, under the carriageway, which are made of materials of higher consistency and quality, or to the deeper soil layers underneath and thus having superior mechanical properties to those of the surface ground flanking the carriageway.
  • the device of the invention in case of a crash of a vehicle on the safety barrier with a very strong component transverse to the safety barrier, the forces are not released only on the ground which holds the supporting pole but are also transmitted to the deeper layers of the road paving (bed, base and foundation levels) being the elongated rigid elements or the bars planted transversely to the longitudinal direction of the safety barrier.
  • the bars are arranged in an inclined manner in respect to the horizontal or to the plane of the carriageway as is shown in the figures. This arrangement increases the crash resistance capability of the supporting poles reinforced by an anchoring device of the invention. However, they may be planted horizontally, if the ground so allows, without departing from the scope of the invention.
  • the supporting pole bends in the zone in which the anchoring device is fixed, plastically deforms and dissipates the energy of the crash.
  • the low consistency of the ground, in the absence of the device which is the object of the present invention, is not an effective constraint for the pole. Accordingly, the latter does not apply its crash resistance function in a transverse direction as provided in design.
  • the use of the anchoring device ensures the correct operation of the safety barrier and the formation of the plastic hinge at the height provided by the designer. The bending point is higher, the higher the coupling element of the anchoring device.
  • the solution offered by the invention can be made at low costs with regard to manufacturing and to installation and maintenance. It can be used on newly built systems and on systems already present in situ.
  • Another non-irrelevant advantage is to provide a minimum visual impact and practically zero dimensions on the road surface, which is not at all changed because the coupling element may be fixed very low onto the supporting pole or even on ground level or even underground, but in all cases close to the road.
  • the coupling element of the anchoring device which is the object of the present invention does not require any replacement, disassembly or modification of the poles already installed or of parts of them.
  • the distal portion of the rigid elongated element or bar is usually either driven or immersed under the road paving transversely to the direction of the safety barrier because in this manner the anchoring device of the invention can withstand the crash components in an optimum manner caused by vehicles crashing in transverse direction, in particular when the crash is orthogonal or nearly orthogonal to the direction of the safety barrier. It is disadvantageous to arrange the rigid element or the bar with an angle of small value, or even more so equal to 0 °, with respect to the longitudinal direction of the safety barrier since this arrangement provides a low resistance to transverse crash forces.
  • the elongated element is generally a round section bar provided with an external thread on the surface to facilitate screwing into the ground and to increase the force needed to extracting it from the ground and arranged in a transverse to the direction of the safety barrier, or substantially orthogonal is pushed or embedded almost always under the carriageway itself. It may also be a bar provided with hooks or discs or surface projections of different shape to a thread, but also to increase the grip in the carriageway or in the ground to increase the force needed to extract it. It can also be a bar with outer surface free of macroscopic added protrusions but left untreated so as to facilitate the friction with the ground into which it is driven.
  • the elongated element may also not be single, but even two or more can be installed, as needed, according to the structural needs of the road safety barrier.
  • the dependent claims refer to preferred embodiments of the invention.
  • the object of the present invention relates to one or more contrast systems placed at the point in which the formation of the plastic hinge and the increase in the resistance to thrusts or impacts with high value transverse components is necessary for the correct operation of the restraint device.
  • Figure 1 shows a diagrammatic, axonometric view of an anchoring device according to the invention
  • Figure 2 shows a vertical section view of an anchoring device according to the invention
  • Figure 3 shows a plan view of an anchoring device according to the invention
  • Figures 4, 5, 6, 7, 8, 9 show various contrast systems of the anchoring device according to the invention.
  • Figures 10, 1 1 , 12, 13, 14, 15, 16, 17, 18 (tie-rods) show variants of the anchoring systems with screws or the like;
  • Figures 19 and 20 (cross section 1 and 2) show two different types of installation (one with screwing tie-rods and one with abutting tie-rods with examples of tie-rods with and without protrusions) of the anchoring device according to the invention. Same reference numbers in the various figures correspond to the same elements or components.
  • Figure 1 shows a safety barrier indicated as a whole by reference numeral 1 , commonly also named guardrail, which comprises a longitudinal bar 2, of the type well known in the road construction art and a pole 3 onto which the longitudinal bar 2 is fixed by means known in the field of technique, for example, but not exclusively, by means of screws, bolts, welding.
  • the pole 3, by means of its end 3' is intended to be fixed to the ground by the sides of the road carriageway.
  • the pole 3 may be fixed to the ground by driving, pushing or hammering or by immersion in the casting of cement or asphalt or other material with which the road superstructure is made.
  • Fig. 1 and fig. 3 show only a very short stretch of a road safety barrier, it being quite apparent to a person skilled in the art that for understanding the invention it is sufficient to refer to a short stretch as shown in the figures because the invention may also be applied to barriers without any limitation of length.
  • these types of safety barrier are also commonly called guardrails.
  • Such safety barrier defines a longitudinal direction, which is generally parallel to the lane of the road along which it is built.
  • the anchoring device indicated as a whole by reference numeral 10 and generally made of metal, in particular steel alloy, comprises a bracket 13, or a tie or collar and, advantageously, two tie-rods 1 1 and 12.
  • the number of tie-rods may be reduced to only one and in case of particular types of materials constituting the road superstructure they could be in number greater than two, without departing from the scope of the invention.
  • the length of the tie-rods may be chosen as a function of the needs, generally it should be sufficient to reach the ground layers which are more compact, as well as the shape, which can be either entirely straight or provided with curved portions.
  • the tie-rods 1 1 1 , 12, made of any material or alloy or any metal section, are connected at one end with the bracket 13, e.g. by means of nuts 14', 14" screwed onto a thread provided at least on the end portion of the tie-rod. It is not excluded that the tie-rods 1 1 , 12 are welded to the bracket 13, if the assembly of the anchoring device permits, e.g. in those cases in which it is immersed in the concrete casting during the road construction.
  • the bracket 13 instead of a simple plate, may also be advantageously made in the form of a ring, the bar 30, yoke, etc. also to take the size and shape of the cross section of the pole 3 into account.
  • the bracket 13 may have different shapes or sections, e.g. C-shaped (element 13"'), U-shaped (element 13"), L-shaped (element 13') and can also be a cord 31 of any material having the necessary strength, can be a hollow or solid cylindrical element. Holes are provided in the elements 13, 13', 13", 13"' to allow guiding and correctly mounting the tie-rods or bars in the ground in the direction transverse to the longitudinal direction of the safety barrier, see figs, from 4 to 9.
  • the bracket 13 may also be formed by a plate and a counter-plate, as in fig. 8, connected to each other by means of two elements.
  • a particularly advantageous embodiment of the anchoring device consists of two tie-rods 1 1 , 12, or more in general of two bars of cross section which may be as varied as possible, L-shaped, C-shaped, H-shaped, etc. which may be provided with surface protrusions of various kinds to promote the grip on the material of the ground or the paving layers in which they are immersed with the surface of the tie-rods.
  • these surface protrusions in radial direction may consist of a thread formed on the surface of the tie-rods 1 1 , 12: this thread may be advantageously formed as a spiral surface with thin but very high thread, since the anchoring device must be always screwed into the ground or into materials which are not very compact, non-limiting examples are shown in Figs, from 1 to 4.
  • the tie-rods 1 1 , 12 can also be helical or half-helical screws, micropiles or steel tubes or other alloys and materials which guarantee adequate resistance to tensile loads. Other types of sections made of steel or any other material or alloy can be used without departing from the scope of the invention.
  • tie-rods are anchor-shaped or hook-shaped on the tip as shown in figs. 10, 1 1 , 13, 14, 18, or C-shaped or U-shaped portions, or the spiral may be formed by winding a further bar of any diameter on the tie-rod along part of the length or along the entire length, as shown for example in figs. 10, 1 1 .
  • the tie-rods can also be cords or have elements such as plates, half-plates and the like, as shown in figs. 12, 15, 16, 17, of the fixed type or which open once inserted into the ground in order to promote more grip.
  • the choice of the length and diameter of the tie-rods 1 1 , 12 is determined by the morphology and type of ground into which poles are driven, the shape of the tie-rods and the mechanical properties of the lower layers of the road paving and/or the ground below the paving and the ability to produce sufficient friction between ground and surface of the tie-rods 1 1 , 12, both when they are inserted by hammering or when they are screwed, as is well known to the person skilled in the art.
  • the anchoring device is intended to be mounted along the pole at an appropriate height with respect to the road surface and with a suitable angle of inclination with respect to the horizontal which can be comprised between 0 ° and 70 ° approximately, to allow an effective reinforcement of the constraint imposed by the ground, e.g. as is shown in fig. 2. If it is necessary and desired, the bracket 13 may also be arranged below the level of the ground, so as not to be visible from the outside e.g. as in figures 19 and 20.
  • the anchoring device 10 for poles after assembling a safety barrier on the poles 3, in case of a crash of a vehicle with the barrier allows to transfer most part of the stresses to the road superstructure, as can be easily understood from the pattern of distribution of the forces shown in figure 2.
  • the force caused by the crash of the vehicle on the barrier 1 , indicated by the arrow 20, is transferred to the ground with a pair of forces which may be approximately indicated with arrows 21 and 22.
  • tie-rods 1 1 and 12 of the anchoring device prevent the pulling out of pole 3 from the ground that the force 20 would tend to cause if it were not for the tie-rods 1 1 and 12.
  • the assembly of the anchoring device is easy, whether it be done during the initial installation of the safety barrier or during an operation intervention following the installation of the safety barrier.
  • the anchoring device is inserted by screwing the tie-rods into the material of the superstructure or by insertion by means of hammering devices or the like, or alternatively holes can made preliminarily in the road superstructure to facilitate the embedding of the tie-rods possibly with the aid of hardening material, such as mortar, resins, etc.
  • the length of the tie-rods 1 1 , 12 is chosen so that it is sufficient to make their distal end, considered in a direction transverse to the direction of the safety barrier, be fixed in a layer of ground which is known to have sufficient compactness, e.g. a layer placed under the road carriageway at the end of the driving operation, to ensure a sufficient resistance against the extraction forces which would occur in the case of crash of a vehicle onto the safety barrier.
  • a layer of ground which is known to have sufficient compactness, e.g. a layer placed under the road carriageway at the end of the driving operation, to ensure a sufficient resistance against the extraction forces which would occur in the case of crash of a vehicle onto the safety barrier.
