Definitions

  • the present invention relates to the field of safety barriers of the type equipping the roads and highways, and consisting of modules that are prefabricated in concrete and follow one another. More specifically, it concerns a device for assembling two such modules prefabricated concrete, as well as a safety barrier aforementioned type and a prefabricated concrete module for a such barrier.
  • a security barrier can be used to temporarily divide a roadway in two sector where work is carried out. It can also constitute a definitive, albeit mobile, separation between two lanes or between one lane and a serviced area.
  • EP-1,162,315 describes such a security barrier which consists of a succession of prefabricated modules in concrete, lengthened and widened at their base.
  • the ends of these prefabricated modules are provided with rings horizontal metal, in which screws of metallic and vertical connections.
  • the upper end each of these connecting screws is provided with a head in support against one of the metal rings.
  • the end bottom of each connecting screw is threaded and screwed in a lower bonnet, in order to stiffen the barrier of security.
  • the latter is subjected to bad weather and, to a certain extent, to the treatments applied to the pavement, such as salting in winter. That is why, several years after the installation of the barrier of safety, the threaded ends of the connecting screws may be seized in the lower covers and therefore impossible to unscrew. If this is the case, the modules prefabricated can not be separated from each other without the concrete that constitutes them being broken, since the connecting screws are difficult to access. This is not satisfactory to the extent that one wishes to be able to reuse prefabricated modules after having them
  • the object of the invention is therefore at least to enable facilitate the dismantling of a safety barrier consisting of a succession of prefabricated modules in concrete, especially when this disassembly takes place several years after the installation of the security fence.
  • the subject of the invention is a device of assembly of two modules of security barrier prefabricated concrete and elongated, characterized in that includes first and second link members, as well as that traction means able to bring these first and second connecting elements of each other, at least the first connecting element comprising two arms of restraint that are directed to the second element of connection and each of which defines one of two ramps tightening eyes of the two prefabricated modules one against the other, these clamping ramps being inclined one by relationship to each other so as to move away from each other towards the second connecting element.
  • the invention also relates to a module of security fence, prefabricated concrete, elongated and fit to be assembled to another security barrier module to using an assembly device as defined previously characterized in that a passage substantially vertical is provided in this module and in that inside of this substantially vertical passage, said module defines at least one inclined ramp with respect to the vertical, towards one end of said module, and able to cooperate with one of the two clamping ramps defined by the first connecting element of the assembly device.
  • the subject of the invention is also a barrier of road or motorway safety, characterized in that that it comprises a succession of prefabricated modules in concrete, lying down, resting on the ground, assembled and such as defined above, as well as at least one device assembly as defined above, which maintains assembled first and second consecutive modules among prefabricated concrete modules, both retaining arms of the first connecting element entering the passages substantially vertical of the first and second modules, said traction means tightening the ramps of the first connecting element on the first and second ramps modules so that these are tight against each other the other.
  • the security barrier shown in Figures 1 and 2 has two prefabricated reinforced concrete elements 1 and 1 ', which succeed each other and that a device assembly comprising a lower connecting element 2, an upper connecting element 3 and two nuts 4.
  • the prefabricated module 1 ' is identical to the module prefabricated 1.
  • a reference used to designate hereafter part of the prefabricated module 1 'identical to a referenced part of the prefabricated module 1 is obtained in adding a '' (prime) to the reference identifying this part on the prefabricated module 1.
  • the prefabricated module 1 which is shown alone to FIGS. 3 and 4, is made of reinforced concrete and presents a elongated shape. It is expanded at its base, in which is formed a longitudinal groove and lower 5. The latter is turned down and connects the ends 6 and 7 of the prefabricated module 1 to one another.
  • the prefabricated module 1 ends by a vertical rib 8. At its end 7, the module prefabricated 1 ends with a surface that delimits a vertical groove 9 complementary to the rib 8 and having a substantially semicircular cross section.
  • a vertical and longitudinal slot 10 opens at the times at the top of prefabricated module 1 and at its end 6.
  • a passage vertical and crossing 11 connects this slot 10 to the throat 5.
  • the module prefabricated 1 defines an upper ramp 11a and a ramp lower 11b.
  • the ramp 11a is inclined relative to the vertical so as to get closer to the 6 end towards the top, while the ramp 11b is inclined with respect to the vertical so as to get closer to the end 6 down.
  • a vertical and longitudinal slot 12 opens at the times at the top of prefabricated module 1 and at its end 7.
  • a vertical passage crossing not visible on the figures, connects this slot 12 to the longitudinal groove 5.
  • An identical passage passes right through the module prefabricated 1 'and is referenced 13' in FIG. inside this passage 13 ', the prefabricated module 1' defines an upper ramp 13'a and a lower ramp 13'b.
  • the ramp 13'a is inclined relative to the vertical in order to approach the end 7 'upwards, while the ramp 13'b is inclined relative to the vertical so as to get closer to the 7 'end towards the bottom.
  • a hollow 14 extending longitudinally is advantageously provided in each flank of the module prefabricated 1 to facilitate the grip of it by a clamp of a hoist.
  • Lower link elements 2 and upper 3 are symmetrical with respect to a transverse plane P and result, for example, from welding assembly or flame cutting metal parts.
  • the lower link element 2 which is shown only in FIGS. 5 and 6, comprises a lower beam and horizontal 15, whose cross section has globally the shape of a U returned.
  • the upper connecting element 3 comprises a beam upper and horizontal 19, in which are drilled two vertical and through holes 20, provided for the passage of rods 18 and offset longitudinally one of the other.
  • prefabricated modules 1 The implementation of prefabricated modules 1 and is carried out using a hoist not shown, after placing the connecting element on the ground lower 2 without the upper connecting element 3.
  • the prefabricated module 1 ' for example, is set up in first, so that one of the rods 18 passes into the vertical passage 13 '.
  • the prefabricated module 1 is put in only then, which is greatly facilitated by the use of the groove 9 'of the module 1' already on the ground as guide for rib 8 of module 1, when lowering of the module 1. In this way, the corresponding rod 18 place correctly in the vertical passage 11.
  • a hood not shown can be arranged to style the security barrier at least at the junction of the modules prefabricated 1 and 1 ', and to protect the device assembly consisting of element 2, element 3 and nuts 4, especially against the weather.
  • nuts 4 are easy access, which facilitates their dismantling. These nuts 4 In addition, they are noticeably far from the ground, which tends to protect them against premature seizure on the stems 18. In the case where the nuts 4 are nevertheless seized and impossible to unscrew, the rods 18 can easily be cut below them, for example by means of a blowtorch.
  • the prefabricated elements 1 and 1 ' can easily be dissociated from each other, even if they are in place for a very long time.
  • the lower link element 2, the upper connecting element 3 and the nuts 4 are not not anchored in the concrete of prefabricated modules 1 and 1 ' and can therefore be easily replaced, which is advantageous in case of significant corrosion after several years of installation on a site.
  • the distance root - vertex d of rib 8 is greater than the maximum depth of the throat 9. Thanks to this and thanks to the substantially semicircular cross section of this groove 9 and the portion of the rib 8 which there penetrates, prefabricated modules 1 and 1 'can be tilted relative to each other in a plane horizontally, as shown in Figure 9, especially to to follow a curved line to the security barrier.
  • the prefabricated modules 1 and 1 ' can also be tilted relative to each other in a vertical plane, while being firmly squeezed together by the assembly device and coupled by the interlocking the rib 8 in the groove 9 '.
