Definitions

  • the invention relates to the public works sector and more specifically to the construction and equipment of traffic lanes, such as roads or highways. More particularly, the invention concerns a new type of crash barriers installed in curbs such ways. It also relates to a method and a machine for setting place of these slides.
  • expressways and in particular motorways have barriers on their shoulders or at the edge of the carriageway forming safety barriers.
  • These slides are generally consisting of the end-to-end joining of longitudinal elements, in profile determined to accept a certain degree of deformation and thus cast down towards the center of the road the vehicles hitting them.
  • the slides are unloaded and aligned on the ground at height of their final location.
  • an installation vehicle supports also called doorbell, traverses the alignment and, at each overlapping area, beats a post. Then two operators raise the slide to be installed and mount it on the support.
  • the next operation consists in securing the newly installed slide installed to the previous one, using nut / bolt pairs. It suits then make an altimetry adjustment and then tighten definitely the bolts. It goes without saying that all these operations are particularly painful and require a large workforce. In in addition, the positioning of such slides is done completely manual and empirical which increases the risk of error and time of execution.
  • the object of the invention is to remedy these drawbacks.
  • the problem which the invention proposes to solve is to improve and to facilitate, on the one hand, the assembly of slides between them and, on the other hand, their placement and fixing on the supports correspondents, with the aim of reducing the set-up time work and to obtain a great precision at the level of the installation.
  • the invention relates, in a known manner, to a safety barrier intended to be mounted between two support elements fixed on the shoulders of a road, comprising at each of its ends a overlapping area allowing on the one hand, the joining with the adjacent slides by means of members passing through holes drilled in look from one slide to another, and on the other hand, solidarity with support elements by means of members passing through orifices provided in look to this effect in each slide.
  • one of the zones of overlap comprises at least one lug oriented along the axis longitudinal of the slide in the middle of it, and in that the other zone has a light on the generator receiving the lug intended to receive the lug of the adjacent slide.
  • the slides have engaging parts ensuring positive attachment of one slide on the other.
  • the pins are punctured parts obtained by cutting the sheet metal of the slide. In this way, it is not necessary to add material additional.
  • the pins advantageously have a fold along their axis of symmetry, parallel to the longitudinal axis of the slide. This arrangement improves the rigidity and the resistance of the pins, while reducing their width and therefore facilitating their introduction into the complementary holes.
  • each zone has four pins, arranged in rectangle on the concave outline.
  • the diameters of the holes, opposite one slide to another are different, to allow the connection by tapered bolts.
  • the use of such self-tapping bolts decreases the number of parts to be used and the execution time.
  • the slides are pre-secured before being put in place at the supports. This allows automation of the installation of supports and the installation of the slide train pre-secured.
  • the invention also relates to a machine for implementing the process described above.
  • the means for orienting the train slides consist of a set of rollers located at the front of the machine according to the direction of advance thereof.
  • the train of slides passes in front a light beam emitted by a device provided for this purpose on the chassis.
  • a device provided for this purpose on the chassis.
  • the hole for hooking with the support is crossed by the light ray, the latter is received by a detector which orders the chassis to stop at the precise place where the support must be fixed.
  • the support reaches a certain depth, the light which it presents to receive the connecting member with the slide lets in the light beam, which gives the order to stop the organ of hype.
  • the threshing means of the support are constituted by a hammer movable along a vertical axis, the head of which has a shape enveloping the upper end of a support, associated with a lower guide and positioning bracket the lower end of the same support.
  • a slide (1) consists of a profiled part metal mounted between two supports (2) fixed in the ground (figure 1). In the form shown without limitation, this profile consists of two convex side portions (1c, 1d) connected by a central portion concave (1e).
  • the slide (1) has a plurality of holes (3) arranged on the same generator (G1) ( Figure 2).
  • G1 generator
  • the holes (4) of the slide located on the side of the pavement are slightly larger in diameter than those (3) of the slide near the shoulder. This arrangement allows the screwing of two slides (1, 1 ') between them by means of self-tapping tapered bolts (5), thus avoiding the use of nuts.
  • lugs (6) are located in the concave portion (1e) of the slide ( Figure 2). These pins (6) are obtained by cutting the sheet of the slide and by deformation of the cut tabs towards the interior. These tabs (6) have a longitudinal axis (A) parallel to the longitudinal axis (L) of the slide, and are oriented towards the middle of the slide. Complementarily, and therefore on the same generators, the opposite end of the slide has superimposable holes (7) to the pins (6).
  • each lug (6) is slightly bent along its longitudinal axis (A) to improve its resistance and decrease its width, and thus facilitate its introduction into the complementary hole (7). In this way, as illustrated in FIG. 6, the hooking of the lug (7) is made safer.
  • the central part of the concave part (1e) is pierced with a orifice (8) intended to receive the member for securing with the support (2).
  • this orifice (8) is slightly oblong for allow a position correction during the installation of the slide (1) on the support (2).
  • the invention also relates to a method of setting places such slides.
  • the presence of pins facilitates the installation of these.
  • the process according to the invention consists in depositing along the roadway, a succession of slides (1, 1 ', 1 ", ). It is important to deposit these in engaging the pins (6) of the running slide (1) in the holes complementary (7) of the previous slide (1 '), already deposited. Of the so, we create a train of pre-secured slides.
  • a twist is produced on the train (1, 1 ', 1 ", ...) of slides which rotates it and presents it vertically, i.e. in the orientation ready for installation.
  • browsing the runners we automatically detect the position of the oblong holes (8) at the overlap areas (1a, 1b).
  • a support (2) is beaten.
  • Such a method can be implemented using a machine (10) characteristic of the invention.
  • This chassis (10a) receives in its front part and laterally, a clearance rollers (10b) forcing the passage of the slide train from one orientation horizontal or flat, in a vertical orientation.
  • this machine includes a threshing device (10c) arranged offset on one side of the frame (10a).
  • This device threshing consists mainly of a hammer (or sheep) (10v1) mounted on a vertical axis (10c2).
  • the part of the hammer (10c1) intended for coming into contact with the support (2) is enveloping, that is to say that it covers the upper end of the support and allows vertical retention of the support, preventing it from tipping over.
  • the lower part of the threshing unit includes a guide bracket (10d) intended to maintain the lower end of the support (2) at the start of threshing.
  • This stirrup (10d) can take the approximate shape of a horseshoe open towards the rear of the direction of movement of the chassis.
  • the frame (10a) has guide elements (10e). optics allowing the installation of supports at positions and heights optimal.
  • these guide elements are constituted by a housing light (10e1) emitting a focused optical beam (F).
  • the direction of this beam (F) is perpendicular to the plane formed by the different supports (2) already beaten.
  • the height of it is very exactly that at which the fastening point (8) of the slide must be located and of the support (2).
  • the optical box (10e1) is associated with a reflector (10e2) arranged on an extension arm of the chassis (10a1), on the other side of the final location of the slide (1).
  • a support (2) is then introduced into the stirrup (10d) and the device threshing (10c) is then activated. Insertion of the support (2) causes the attachment light (2a) to descend (figure (9).
