Definitions

  • the present invention relates to a safety barrier intended to ensure the road safety of motor vehicles on road axes and to avoid their departure from the road.
  • a safety barrier which is formed by at least one horizontal heald made up of wooden heald elements and by wooden posts each supporting two adjacent heald elements, each element being provided, each of its ends, of a metal frame allowing its connection to the adjacent end of a neighboring heald element.
  • the heddle is placed on the top of the posts and its elements are connected end to end, using a metal plate in the shape of a "T" whose wings are introduced into vertical and axial slots of two neighboring heald elements and the lower part of which is introduced into a vertical slot formed in the upper end of the associated post, the assembly being produced by bolts passing right through, the post, the heald elements and the plate.
  • the metal "T" plate used in these embodiments is relatively long and expensive to manufacture.
  • each metal frame consists of at least one metal splint profiled with curved longitudinal edges so as to have a "U" cross section and a part of which is fixed, on the one hand, to the periphery of the end of a heald element substantially parallel to the axis thereof ci by means of at least one bolt passing through it and, on the other hand, on the periphery of the adjacent end of the neighboring heald element by means of at least one bolt passing through.
  • this splint has a better moment of inertia and, consequently, a better resistance to bending than a flat iron, this improvement is limited by the fact that the height of the curved longitudinal edges must remain low, since they must penetrate the heald elements.
  • the present invention relates to a safety barrier of the aforementioned type, which is easily removable, which offers the possibility of easy replacement of the different beams which constitute it and which, on the one hand, due to its simple design and, on the other hand, the material in which it is carried out, or at a relatively low cost, while exhibiting excellent mechanical resistance properties, in particular to bending and tensile forces, and making it possible to avoid any discontinuity in the alignment of the different heddles.
  • each heald element being provided, at each of its ends, with a metal frame allowing its connection to the adjacent end of a neighboring heald element and in which each metal frame is constituted by at least one metal splint, each splint consists of at least one metallic tubular element housed, substantially in half, in two recesses placed end to end, each recess being hollowed out in one of the two adjacent ends of two successive heald elements.
  • each fishplate has a polygonal cross section such as rectangular and the recess of the end of each heald element is of complementary cross section and is located so as to open into the substantially cylindrical wall of the heald element considered.
  • the polygonal section, such as rectangular, of the splint gives it good resistance to bending, greater than that of the flat metallic splints revealed by the aforementioned European patent as well as those whose longitudinal edges are curved, revealed by the request. of the aforementioned first addition.
  • the insertion of the splint into the recess of complementary shape of the end of the associated heald element thus makes it possible to ensure a very good connection between the different heald elements which, for this reason, have excellent flexural strength in the areas of these bonds.
  • this splint which makes it possible to consolidate the connections between the heald elements, thanks to its positioning inside the core of the heald elements, can be made invisible from the road at the edge of which this slide is installed. , to give the latter an appreciable aesthetic appearance. It suffices for this that the recesses of the heald elements which receive the ribs also open, laterally, in the posterior or lower part of the heald elements. Thus, the disassembly and reassembly of each heald element independently of the adjacent elements does not present any difficulty.
  • a reinforcing means of the flat iron type is provided, covering the heald element laterally and over its entire length.
  • This flat iron which covers the heald element laterally and over the entire length, makes it possible to reinforce the flexural and impact resistance of this heald.
  • each splint has at least two pairs of coaxial through holes for the passage of at least two bolts, each of which passes through one of the two stringer elements assembled by this splint.
  • each tubular splice is of circular cross section and each end recess of the heald element is of complementary circular section and is disposed axially to the heald element considered.
  • each end of each heald member has a radial slot making the corresponding central recess communicate with the outside and the central recess of at least one end of each heald member has a length double that required to accommodate a splint.
  • This housing is therefore capable of receiving and housing, during the mounting or dismounting of the neighboring heald element, the entire splint.
  • This housing thus allows an easy and quick disassembly and replacement of a heald element of this slide without the need to dismantle this slide from its nearest end. Indeed, after removal of the fixing bolts of the joint considered, by simple introduction of a suitable mechanical means in the slot connecting the corresponding recess to the outside, it is possible to slide this joint into the bottom of the 'recess the longest and, therefore, to free from any link the two beam elements considered.
  • FIG. 1 shows a safety barrier 1 according to a first embodiment of the invention.
  • This slide is formed by a horizontal rail 3 constituted by substantially cylindrical rail elements 4, made of wood, linked to each other, end to end and by posts 7, also made of wood, firmly planted in the ground. and supporting the heald elements in the vicinity of their connection zones.
  • the elements 4 forming the heddle 3 have a variable length between 1 and 3 meters, but generally from 2 to 3 meters and a diameter which varies from 100 to 300 millimeters and preferably from 150 to 250 millimeters.
  • the dimensions of these elements 4 of heald 3 are obviously determined as a function of the maximum speed authorized on the roads equipped with these safety barriers.
  • each element 4 of heddle 3 and each post 7 is made of a wood of the pine, fir, spruce, larch type which has previously undergone an appropriate treatment.
  • each element 4 of heddle 3 is provided, at each of its ends, with a metal frame constituted by a splint 5 allowing its connection to the adjacent end of an element 4 of neighboring neighbor 3.
  • Each splint 5 is constituted by a metallic tubular element, housed, in half, as illustrated in FIGS. 2, 4 and 5, in two coaxial recesses 6 of two ends placed end to end of two successive elements 4 of the smooth 3 adjacent. These recesses 6 are hollowed out in the ends of the elements 4 smooth 3.
  • the splint 5 is of rectangular transverse section and the recesses 6 formed in the ends of the heddle elements 4 are of complementary rectangular section and their length corresponds substantially to half that a splint 5 to be able to receive and house about half of it.
  • each recess 6 is located so as to open into the lower part of the cylindrical wall of the heald element 4 considered.
  • the recesses 6 of the ends assembled to each other of the heald elements 4 are arranged so as to open into the rear part of the cylindrical wall of the heald elements considered .
  • the rectangular section of the fishplates 5 gives them a good resistance to bending much greater than that of the previously known flat metal fishplates.
  • this fishplate 5 is invisible from the road at the edge of which this slide is disposed, which gives it an appearance appreciable aesthetics.
  • each fishplate 5 has two pairs of coaxial through holes intended for the passage of two bolts 10 for assembling the fishplates 5 to the two adjacent heald elements 4 3, assembled by this fishplate.
  • a flat iron 15 is fixed laterally, to each heald element 4 and over its entire length, by means of bolts 19, in order to improve its resistance to impacts, to traction and to bending.
  • a flat 12 is arranged laterally over the entire length of each element 4. The connection between two consecutive flat bars 15 is ensured by the covering of their ends crossed by at least one bolt 19.
  • each splint 5 ′ is of circular cross section.
  • Each splint 5 ′ is intended to be inserted in two corresponding recesses 17 each of which is pierced axially in the end of a member 4 of heddle 3.
  • each recess 17 communicates with the outside by a radial slot 18.
  • each heald element 4 has a length equal to twice that of the other, that is to say equal to the length of a splint 5. This arrangement which allows the erasure of the entire splint 5 in this recess greatly facilitates the disassembly of a heald element of this slide.
