Definitions

  • the present invention relates to curbs and how to make them reflective for better visibility at night and in particular a process continuous installation of a curb reflective and the means of implementation.
  • the installation of the borders can be carried out either by assembling prefabricated border elements in the factory either in situ.
  • the installation of prefabricated elements is unfortunately expensive, slow and causes problems lumbar to the workers in charge of the installation.
  • the process of embedding glass beads in the concrete is also crucial for making curbs of good quality while using an efficient and fast installation.
  • the patent FR 1441.061 describes a process incrustation of the balls by projection under pressure relatively large. This process is unfortunately ineffective, whether performed in situ or in the factory. Indeed, when made directly on site, concrete is delivered by “router” trucks and has plasticity variable for each truck arriving on site. In plus, the unloading time and the progress of the work are also factors that modify the plasticity of concrete. This variable plasticity should then be determined in each case so as to adjust the pressure used for the projection of the balls. It is the same when the elements are produced in the factory as long as the plasticity of concrete is different from one mixer to another and evolves between the period of pouring, demolding and projection of the balls.
  • the object of the invention is therefore to implement a continuous installation process for curbs reflective that is fast, that can adapt in permanence of the plasticity of the concrete used and which does not cause difficulties for the persons in charge of the installation of the borders.
  • the object of the invention is a method continuous installation of a curb on the surface reflective consisting of glass beads, consisting of pour the material to constitute the border to the place where it must be laid, to mold the border to give it its final shape, to flow beads on at least one of the sides of the border, and embed these beads in the border material by application of a pressure which is a function of plasticity of the material constituting the border.
  • Another object of the invention is a setting machine continuously using the above process.
  • a border of pavement 10 manufactured by the method according to the invention comprises on the vertical face 12, the inclined face 14 and the horizontal face 16, spherical balls 18 embedded in the material 20 constituting the border 10, generally of the concrete. It should be noted that, although the beads are encrusted with preferably, they could be fixed to the surface of the reflective sides of the border by any other means without depart from the scope of the invention.
  • the spherical balls 18 are preferably juxtaposed so as to cover the maximum surface area of concrete 20.
  • the balls 18 are of preferably transparent glass beads but which can be in any other transparent material such as plastic material. They are microscopic, of a diameter generally between 100 microns and 2 mm. Due to the light refraction by the balls as well as the light reflection due to the interface between the balls and concrete, light from public lighting or headlights car is thoughtful and provides effective visibility of curbs at night.
  • This machine advances from left to right and allows continuous laying of the curb.
  • a concrete inlet hopper 30 At the head is a concrete inlet hopper 30.
  • the concrete is then compacted by means of a worm screw 34, which allows give good homogeneity to concrete.
  • the border is molded into its final form by the formwork mold sliding 36.
  • a small hopper 38 allows the arrival microbeads 40 on the faces of the border where the microbeads should be embedded.
  • the rear of the hopper is extended by sets of two metal parts, a first part 42 parallel to the border and a second part 44 formed of planes inclined with respect to the surface of the border where the microbeads will be embedded.
  • the inclination of the second part 44 is determined by a screw (or more) 46 bearing on the first part fixed 42.
  • the pressure exerted by the inclined part 44 on the balls on the surface of the molded concrete cause their concrete inlay.
  • the screw 46 allows the adjustment of the pressure exerted on the balls and the angle of inclination of the elements of the second part 44 relative to the first part 42. This adjustment is a function of the consistency and plasticity of the concrete. If the humidity of the concrete is high (concrete wet) the pressure should be low. Conversely, with a low humidity (dry concrete), pressure necessary will have to be more important. Depending on what setting, the angle of inclination will vary between 2 and 10 °.
  • the number of elements of the second part 44 varies in function of the number of faces on which we proceed to the inlay of beads.
  • three sides of the border give rise to inlay, so you have to plan three inclined elements for the second part 44 as well as a first part 42 having a shape corresponding to that of the border but a slightly larger in height and width, the two pieces being integral at the front and made integral by one or several screws 46 at the rear.
  • a machine according to the invention has a weight about 350 kg. It has cylinders allowing a height adjustment and precise tilt correction. She allows the realization of all types of borders of a maximum dimension of 50cm high and 60cm wide, and therefore of all standard borders (more than 50 references of mussels). This machine thus makes it possible to carry out bituminous concrete beads, colored borders, disabled or throated. The possibility of interchanging the side extrusion, right or left, allows connection to existing works. Note that this is the compaction of concrete by means of the worm which allows the displacement of the machine at a speed between 1 and 6m per minute.
  • the method of making a curb reflective which has just been described does not imply carrying heavy loads for workers, allows fast execution as well as great mobility and adapts in permanence of the plasticity of concrete. Its cost is very significantly lower than that of prefabricated borders and applies to all types of borders. It very improves significantly the night road safety sought in permanently by the Departmental Directions of Equipment, General Councils and Communities Local.
