Definitions

  • the invention relates to the technical sector of equipment for road networks, and more generally for all equipment requiring the channeling of passageways of all uses.
  • slides which can be made from wood or metallic material.
  • the safety rails made of wood are in fact made up of logs positioned on duly spaced posts corresponding to the lengths of the logs.
  • This type of slides if it is aesthetic, ecological and non-deformable, in the event of a weak force impact, nevertheless has significant disadvantages. More particularly, the risks of rapid breakage are signaled in the event of a major impact, the slides no longer playing their retaining role.
  • metal slides which have tended to replace the previous ones.
  • metal slides also have many drawbacks inherent in their production.
  • Safety barriers are also known which are made from a very long metal cable, and in particular several hundred meters, positioned on posts arranged at regular intervals or not.
  • This type of slides has serious drawbacks in the sense that they provide a "piano cord" function with an elasticity effect and therefore an extremely dangerous deflection for vehicles or other elements or products liable to come into brutal contact against it. .
  • the aim sought after according to the invention was to design a new safety barrier which is capable of meeting all of the safety criteria relating to these conditions of use, while retaining a marked aesthetic and ecological appearance.
  • Another aim was to design a new type of slide for easy maintenance and repair, even temporary, at very low maintenance cost conditions.
  • Another sought-after goal was to design a safety barrier which perfectly fulfills a role of restraint during impacts, while limiting its deformability over a great length which can thus lead to reduced repair and maintenance costs.
  • Another object sought after according to the invention was to design a safety barrier which is particularly capable of adapting very easily without deformation of its constituent elements to the profile of a road or the like.
  • the road safety barrier is remarkable in that it is constituted by modular elements hinged together at their ends and fixed on support posts, each modular element comprising a sleeve having the shape of a log or have the appearance of this latter hollow internally to receive a central stiffening core forming an insert and having a capacity of elastic deformation sufficient for shock absorption, said core projecting at its ends from the sleeve and being fixed to profiled flanges arranged and centered at the end of the sleeve, said flanges being fitted out to allow the chaining of modular elements and their attachment to the posts.
  • the central core is a metal cable.
  • the central core is a prestressed metal cable.
  • Figure 1 is a perspective view of a safety barrier according to the invention before mounting and positioning of one of its ends on a support forming a post.
  • Figure 2 is a longitudinal sectional view of a safety barrier as a modular element after mounting of its constituent elements.
  • Figure 3 is a partial sectional view along line B-B of Figure 4 showing the articulation of two consecutive safety barrier elements according to the invention.
  • FIG. 4 is a side view in section along the line A-A in FIG. 3.
  • Figure 5 is a partial view of a receiving post from one end of the crash barrier.
  • Figure 6 is an alternative view showing the installation and fixing system of the end of a safety barrier.
  • Figure 7 is a schematic view showing the positioning of several elements modular components of end-to-end safety barriers.
  • Figure 8 is a schematic view showing a frontal impact on one of the slides.
  • Figures 9 and 10 are schematic views showing the deformation and breakage of one of the crash barriers, then the outward movement of the slide concerned and adjacent slides relative to two support posts.
  • Figure 11 is a schematic view showing the articulation of the slides together for their positioning adapted to the profile of a wheel.
  • the safety barrier according to the invention is remarkable in that it is constituted by modular elements (E) hinged together at their ends and fixed on support posts (2) arranged at regular intervals or not.
  • Each modular element comprises a sleeve (1) having the shape of a log which can be constituted by the log itself or have the appearance of the latter.
  • Each sleeve or log of wood or other material is hollow internally to receive a central core (3) of stiffening forming an insert and having a capacity of elastic deformation sufficient to absorb shocks including strong violence without destruction.
  • This core or insert (3) projects beyond its ends (3.1 and 3.2) of the sleeve or log, and is fixed to profiled flanges (4 - 5) arranged and centered at the end. of said log.
  • profiled flanges made of any suitable material form a nozzle (4.1 - 5.1) nestable in the opposite end of the log and is extended on the other side with a profiled tab (4.2 - 5.2) capable of constituting a fastening piece and fixing on the corresponding post (2) for installing the slide element.
  • the tab (4.2 - 5.2) is substantially offset relative to the median longitudinal plane of the log or sleeve in order to allow a superimposition of another tab associated with the flange of the modular element adjacent to the slide.
  • Each tab thus has an oblong opening (4.3 - 5.3) allowing the introduction and the passage of a connecting and articulation axis (6) with spacer ring (7) and fixing screw (8).
  • the mounting of two consecutive modular slide elements is carried out by positioning their respective tab in superposition to ensure the fitting of the connecting elements and thus the chaining of the modular elements between them.
  • This implementation is particularly suitable because it in fact allows uniformity in the production of the flange elements (4 and 5) and therefore a simple different angular positioning as a function of their position.
  • the flanges (4 - 5) can be arranged with one having a screed shape and the other having a single tab capable of engaging and fixing itself inside the screed shape mentioned above. using any suitable connection means such as the rod (6).
  • the latter is fixed to a support base (9) of any material having on one of its faces a stud (9.1) capable of penetrating into a slot or additional profile (2.1) made on the post (2).
  • the above-mentioned slot essentially serves for positioning and fixing the connecting element of the modular elements together.
  • this slot is oriented in a plane parallel to that of the road for reasons which will be mentioned later. If necessary, provision may be made for fixing the support base by screws, studs or the like on the transverse face opposite the post.
  • FIG. 5 there is illustrated a metal plate (10) positioned on the transverse face of the post and on which is likely to come to bear the aforementioned support base.
  • FIG. 6 there is illustrated in a variant a support device for the articulation of two modular elements between them which can be fixed on a post.
  • this device comprises a profile (11) coming to cap by its base (11.1) the end of the post and having an inverted U shape of which a wing (11.2) is in a plane parallel to the aforementioned base (11.1) in a horizontal plane.
  • the latter receive guides (11.3 - 11.4) capable of receiving the means of articulation and connection (6) of the legs (4.2 - 5.2) of the associated modular elements. It is obvious that any other method of connection and attachment to a pole can be envisaged.
  • the core (3) is made of an elastically deformable material but having a very high impact rigidity, so as to be unbreakable.
  • This core can thus be constituted by a metal cable, by a cable obtained in composite material with glass fibers, of carbon or the like, giving it great resistance to impact.
  • the metal cable can be prestressed according to techniques known to those skilled in the art, the cable being thus tensioned when fixing its ends to the retaining flanges (4 - 5).
  • a retaining counter-force is obtained by the addition of the resistance and elasticity forces given by the multiplication of a length of the elastic core over two or three lengths of modular elements or more generating an elastic tensioning and retaining effect proportional to the lengths displaced, while perfectly mastering this effect.
  • the safety barrier object of the invention constituted by several modular elements as described offers a multitude of advantages. It is aesthetic by the appearance given by the wooden sleeves or logs. It is ecological in the sense that it fits perfectly into the environment of the installation site.
  • the slide is very solid and safer. It is also emphasized that this type of slide is easy to maintain and easy to repair without excessive cost of intervention. This slide is impassable even in the event of a violent frontal impact.
  • the constituent modular elements are of variable length and their articulation between them allows their adaptation and positioning to all road profiles or the like.
  • the core or insert such as cable for example can be greased while being protected from the weather.
  • the core or insert such as cable for example can be greased while being protected from the weather.
  • the length of the slide elements are of the order of two to three meters.
  • the slide elements are installed after the posts have been installed.
  • the modular elements are securely attached to each other but quite fragile on the pole heads.
  • the column elements are repaired either by changing them or by fixing additional retaining elements.
  • the modular element broken by its sleeve or log part can be replaced very easily.
