Definitions

  • the invention relates to a protection and display device intended to be adapted to concrete lane separators installed on roads and motorways, separators of the type produced by machines with sliding formwork.
  • Concrete separators are made without a preformed joint so that relatively anarchic cracks appear after a certain time. These cracks are relatively large every ten or fifteen meters while small cracks occur every three or four meters.
  • the concrete track separator has a height from the ground of about 80 cm. This height sometimes allows the headlights of cars driving in opposite directions to be visually turned off for the driver who runs alongside the concrete lane separator. However, in most cases, these dividers are not high enough to obscure the lights of the headlights of oncoming cars.
  • the anti-dazzle systems currently produced are very expensive and are dangerous because they are liable to break. These devices consist in particular of nets stretched over metal supports or of vertical blades placed and sealed on the upper part of the concrete track separators.
  • the object of the present invention is to remedy these drawbacks and proposes to create a protection and display device intended to be adapted to concrete track separators, of a relatively low cost price, of easy assembly and allowing not only the protection of cracks in the concrete lane separator, but also a better materialization of the upper line of the concrete lane separator, hence greater safety for the motorist.
  • the present invention aims to create a protection device and visualization of concrete lane dividers to obscure the lights of cars traveling in opposite directions.
  • the invention relates to a protection and display device intended to be adapted to concrete lane dividers installed on the highway to highway separators of the type produced by machines with sliding formwork, device characterized in that it consists of at least one protection and display gutter fitting onto the upper part of the separator, the section profile of the gutter being of shape corresponding to the shape of the upper edge of the concrete channel separator.
  • the gutter helps protect small cracks that occur in the concrete lane separator against water infiltration, and therefore against frost in winter.
  • this gutter generally of various colors, makes it possible to materialize the upper line of the separator.
  • the gutter has a general shape of U.
  • the gutter is fixed to the concrete track separator by gluing, this results in very great ease of assembly.
  • the sides of the gutter serve as supports for reflective strips of light.
  • the gutter is surmounted by a parallelepipedal deflecting plate, one of the longitudinal fields of the plate being arranged in the extension of the vertical median axis of the channel separator.
  • the deflector plate in particular makes it possible to sufficiently close the lights of vehicles traveling in opposite directions, thus avoiding blinding motorists.
  • the deflector plate is provided with stiffening ribs.
  • the deflector plate is provided with orifices of circular or polygonal shape.
  • the orifices of the deflector plate are staggered.
  • the orifices of the deflector plate are slots.
  • the orifices and slots provided in the deflector plate allow better resistance by letting air and debris carried by the wind pass.
  • the orifices of the deflector plate are determined by blades in the form of louvers.
  • At least one of the ends of the device is provided with cutouts for the fixing by overlapping of two successive gutters.
  • the gutter and the deflector plate form a modular monobloc assembly.
  • each modular monobloc element is made of a synthetic material such as polyvinyl chloride.
  • each modular monobloc element is made of a metallic material such as aluminum or galvanized sheet.
  • the deflector plate is colored.
  • the protection and display device 1 consists of a gutter 2.
  • the p _ wire of this gutter, seen in section, is of forma corresponding to the shape of the upper edge 3 of the separator concrete tracks 4.
  • the concrete track separator is of the type designated by the expression (DBA) meaning double adherent concrete.
  • the channel separator in. Concrete 4 is produced using a sliding formwork machine. Such a separator is made without a preformed joint so that after a certain time large cracks appear 5 approximately every ten or fifteen meters, while in the upper part 3, small cracks occur.
  • gutter in general U shape fits on the upper edge 3 of the separator 4. It protects the separator 4 against water infiltration in the cracks 5, 6 and, consequently, against freezing.
  • the gutter 2 is fixed to the edge 3 by bonding points.
  • the sides 7 of the gutter 2 serve as supports for reflective strips of light. This allows the meterization of the upper line of track separator 4.
  • the gutter 2, according to this embodiment, is made of a material such as polyvinyl chloride which is an inexpensive plastic material.
  • the gutter 2 is produced by extrusion and can be produced in different colors. In principle, the chosen color is white, but it is also possible to color the gutters in green and red or to alternate these different colors depending on demand.
  • the gutter 2 better materializes the upper line of the lane separator 4, the vehicles traveling on lanes in the opposite direction according to the arrows F and F ′,
  • the gutter 2 is surmounted by a deflecting plate 8.
  • This deflecting plate is of generally parallelepipedal shape, one of the fields 9 of the plate 8 being arranged in the extension of the vertical median axis XY of the channel separator 4.
  • the deflector plate 8 is produced from a sheet of synthetic material such as polyvinyl chloride.
  • the deflector plate 8 is provided with stiffening ribs 10 resulting from the extrusion.
  • the deflector plate 8 is provided with circular orifices 11 staggered. It is possible to provide orifices of shapes other than circular, such as for example polygonal orifices or slots etc. The arrangement of these orifices is also left to the choice of the request. The orifices are intended in particular to allow air and debris entrained by the wind to pass, which makes it possible to obtain better resistance and less rapid wear.
  • the deflector plates 8 sufficiently close the lights of vehicles traveling in the opposite direction so as to avoid the driver from being dazzled or blinded. Indeed, in this case, the only vision of the lights that remains for the driver is a blinding or lateral vision.
  • the height of the deflector plates 8 is chosen according to the nature of the terrain where the concrete track separator is installed.
  • the gutter 2 and the deflector plate 8 form a modular monobloc element the length of which can be one, two or three meters, so as to facilitate transport and installation, while making it possible to follow the turns or the deformations of the profiles. in lông.
  • Each modular monobloc element 12, 13 each formed by a gutter 2 surmounted by a deflector plate 8, is provided at one of its ends with specific cutouts not shown in this figure for the fixing by overlapping of two successive gutters 2 or of two successive modular monoblock elements 12, 13.
  • the overlapping of a first element 12 on the second element 13 is carried out in the direction of descent so that water cannot penetrate between two successive elements 12, 13.
  • Each modular monobloc element 12, 13 is made of a synthetic material such as polyvinyl chloride. It is also possible to provide for an embodiment of the one-piece elements modular 12, 13 made of a metallic material such as aluminum or galvanized sheet.
  • the modular monobloc element 14 constitutes a second embodiment. It is formed by a gutter 2 of general U-shaped profile, this gutter 2 being surmounted by a deflector plate 8.
  • the deflector plate 8 comprises orifices constituted by blades 15 deformed when hot when it is polyvinyl chloride.
  • the blades 15 are in the form of louvers and allow the passage of air and debris carried by the wind, while avoiding the dazzling of conductors by the lights of vehicles traveling in the opposite direction.
  • the modular monobloc element 16 is a third embodiment. It is formed of a U-shaped gutter 2 surmounted by a deflecting plate 8.
  • the deflecting plate 8 is provided with cutouts of polygonal shape 17, these cutouts being staggered. It is of course possible to provide other arrangements of the orifices while obtaining the same objects as those sought by the present invention.
