Definitions

  • the present invention relates to a setting device in continuity of safety barrier elements for tracks road and motorway.
  • the barriers cast in place are non-deformable and almost impassable by heavy goods vehicles. However they are not reusable in case of modification of the way.
  • Prefabricated barriers currently used consist of elements assembled end to end by pieces metallic, sometimes with ground connections. For some reasons for installation, the play of these assemblies is always important. Ground connections by beaten plugs or massive anchors are often embarrassed or even dangerous to perform, because of the presence of underground networks or structures. During the impact of a vehicle, all the assemblies gets under tension and, in the impact zone, the barrier moves laterally by a value often incompatible with the site.
  • the present invention aims to remedy these drawbacks prefabricated barriers by providing a device of continuity of the elements which eliminates the games assembly and gives them behavior similar to barriers cast in place. It does not require anchoring in floor.
  • the device provides one or more horizontal frames, housed in reservations and connecting all the elements.
  • the elements come closely in contact each other through their ends.
  • the frames are tense and cancel the games between the elements.
  • the capacity barrier restraint can be adjusted to suit the number and tension of the reinforcements.
  • the barrier resists by combination of the following two effects.
  • the section resists thanks to the prestress brought by the reinforcement.
  • the barrier opposes lateral displacement thanks to the compression generated by the shock.
  • any lateral deformation in the center of a rectilinear beam implies a slight displacement of its ends along its axis.
  • the resistance provided by the friction of the elements on the ground is sufficient to block this movement.
  • a large part of the shock energy is then transformed into compression force in the barrier. Concrete withstands it particularly well. This effect is an important part of behavior of barriers in place.
  • the elements precast concrete currently in use are capable of mobilize these two effects.
  • Their weight is important, from about 600 kilograms for one meter of element.
  • Their width at the base about 60 centimeters, is sufficient to create the geometric effect of distance from the ends of the file.
  • the barrier is not adherent to the ground which allows it, during a violent shock, to deform slightly, at the difference of the barriers cast in place denounced for their too much rigidity.
  • the device which is the subject of the invention provides that the end surface of each element must be perfectly flat and perpendicular to the longitudinal axis to ensure a intimate contact of the elements with each other.
  • the frames are type of those used for anchors in the ground. They have the advantage of having a rustic thread on their entire length which allows site manipulation. They can be joined by sleeves with room for inside reservations and they admit in every way tension locking nuts.
  • the device is mounted without bonding product between the elements, or injection of reservations. It is therefore easily removable and all of its elements are reusable. However in some applications, for a line end very exposed to shocks or for an exposed curve on the concave side for example, it is sometimes necessary to bond the elements to the floor concrete and / or filling of vertical joints in curves to locally strengthen the resistance of the barrier.
  • Figure 1 is a perspective view of the device the invention.
  • Figure 2 is a longitudinal sectional elevation view of the device of FIG. 1.
  • Figure 3 is a partial view in longitudinal section of the tension blocking device.
  • Figure 4 is a partial view in longitudinal section a continuity tube between two elements.
  • Figure 5 is a partial cross-sectional view of the device of FIG. 4.
  • the the invention is applied to a barrier 1 having a profile classic says “Californian".
  • the device is characterized by two longitudinal reinforcements 2 connecting all the elements 1 and by perfectly flat and perpendicular end surfaces 3 to the longitudinal axis of each element 1. All elements 1 are in close contact with each other by the tensioning of the fittings.
  • Figure 2 shows the position of reservations 4 welcoming the reinforcements 2 and the presence of a conical draft 5 at each of their ends.
  • a conical projection of the formwork generally metallic, provides support to center a tube, usually in pvc, which constitutes reservation 4 and created by the same occasion the skin 5.
  • the figure also shows the cross section of two water passages 6 which are an arrangement common for this type of barrier.
  • Figure 3 illustrates the role of the conical draft 5 in end of reservations 4.
  • the juxtaposition of the two bodies 5 allows the housing a support piece 7 and a nut 8 for locking of the tension of the armature 2.
  • This support piece 7 has the shape of a truncated cone having an apex angle identical to that of the body 5 and is pierced in its axis to leave transition to frame 2.
  • the fittings 2 are threaded into the reservations 4.
  • the tensioning is done without special concrete element. Of even all or part of the barrier can be easily relaxed and be reused on another site.
  • Figure 4 illustrates the possibility of placing a small length of metal tube 9 inside the reservation 4 in line with the joint between two elements 1.
  • This tube 9 remains localized at this location thanks to a shoulder 10 prisoner in the bodies 5.
  • This tube 9 is useful in certain applications to provide or enhance shear strength at the joints and / or the mechanical continuity between elements 1. This is the case of an installation without reinforcement in a temporary site protection for example.
  • This device can be applied to prefabricated elements of any kind other than concrete, such as metal or plastics for example, or of a section other than that presented in the drawings. Thanks to its ability to be modulated in resistance, the device can be used for all types of safety barriers on motorways, roads, cycle paths, test or sports circuits, etc., and more generally in all areas requiring improvement in mechanical continuity of a line of juxtaposed elements.
