Definitions

  • the invention relates to a modular retaining device for roadways and a method of laying such a device.
  • Restraint devices are road safety devices located along vehicle traffic lanes and intended to prevent a vehicle from passing beyond this edge. These devices can be arranged at the edge of a road or between two lanes as lane separators. Their holding capacity is defined by standards such as the European Standards EN 1317.1 and EN 1317.2 describing tests TB42 and TB11 whose level H1 corresponds to the level BT4 of the French Standard XP P98453. These tests test the impact of a heavy vehicle (TB42) of 10,000 kg at 70 km / h at an angle of 15 ° and a light vehicle (TB11) of 900 kg at 100 km / h at an angle of 20 °. In each case, the displacement of the device must be less than a predetermined limit for the standard to be respected.
  • Existing modular restraint systems whether located at the edge of a road or between two lanes as lane separators, consist of modules having a generally trapezoidal profile with a wide lower base and a narrow top. These modules are connected to each other by means of bolting systems (see for example EP-0997-582-A1 ). While a bolt fastening is acceptable in the case of a restraint system mounted in a fixed position or at least for a long period of time, the use of such systems on short-term work sites, that is to say for a temporary markup, proved to be disadvantageous because of the time of assembly and disassembly important occurring at each installation or at each change of place of these devices.
  • the object of the invention is therefore to propose a modular retaining device allowing both a rapid introduction of the elements or modules of the component and the establishment of a sufficiently strong connection between these elements or modules so that the retaining device can meet the regulatory requirements of road safety for the restraint of a vehicle light and of a heavy vehicle according to the norms indicated above, in case of accidental lateral exit.
  • the object of the invention is achieved by a modular retaining device for roadways as defined in claim 1.
  • the retaining devices according to the invention consist of modules or elements having a sufficiently wide base to ensure a stable position when placed on a road. They can have various forms including various cross sections. Preferably, the modules or elements of the retaining devices according to the invention have a general trapezoidal section with a wide lower base and a narrow upper vertex. However, elements having for example a rectangular general section are also conceivable without departing from the scope of the present invention.
  • the elements or modules According to their arrangement at the edge of a road or between two lanes as track separators, the elements or modules have one or two profiled lateral faces.
  • the first relative position between two elongate elements is essentially that in which one of the two elements to be connected or, subsequently, to separate is based on on the road while the other elongated element is kept in suspension close to the element placed, in order to be able to engage or, thereafter, separate the connecting means from each other.
  • the second relative position between two elongated elements is that where the two elongate elements rest on the road, the connecting means then being engaged in each other.
  • first relative position of two elongated elements according to the invention would be characterized exclusively by a vertical shift of one of these two elements relative to the other.
  • any other orientation of the shift is also conceivable without departing from the scope of the present invention.
  • the first and second relative positions of two elongated elements according to the invention are not limited to the notion of a level shift between the two elongated elements, but also include applications where the longitudinal axes of these two elongated elements form an angle between them and those where the connecting means are shaped for an angular approximation of these two elongated elements during their installation.
  • the device according to the invention consists of elongated elements interconnected by connecting means. which, when engaged in each other, form a link having an axial clearance, so that each element can be worked separately.
  • the axial clearance has a value of between 2 mm and 12 mm, advantageously between 3 mm and 9 mm, and is typically 7 mm.
  • the elements used in the context of the present invention are called "elongated elements" because of their length much greater than that of short elements, concrete or plastic, used for a long time to form temporary separators lane on building sites.
  • the elongated elements used in the context of the present invention have a length of the order of 6 m, a height of about 80 cm and a width at the base of the order of 55 cm. Their weight is of the order of 600 kg. It is intended to manufacture these elongated steel members, but hollow elements of synthetic material, filled or filled with a heavy material, are also conceivable.
  • the elongated elements according to the invention have two important characteristics for their effectiveness, one being the elasticity of the material in which they are made and the other being their adhesion on the road.
  • the material it must be sufficiently rigid to allow the elongated elements to withstand, during an accident, both the impact of a vehicle and the opening of the links between the elements of the vehicle. device. At the same time, the material should not be too rigid either, to avoid the accidental return of a vehicle on the track.
  • the elongated elements are provided with a deformation zone located in their lower part.
  • the elements of the retaining device according to the invention are provided with connecting means which can not engage each other than the time that two successive elongated elements are in a first relative position, which is in general that of an element placed relative to an element to be laid.
  • the connecting means of the device according to the invention can engage with each other only for the time that the corresponding ends of two successive elongated elements, in general therefore of a posed element and an element to pose, are located at different predetermined levels.
  • the two elongated elements When the two elongated elements are placed, they are in the second relative position, in which the link is effective and should open only when the one of these two elongated elements which was last laid, is moved, for example raised to a predetermined level, so that the two elements are again in the first relative position. Otherwise, the requirements of the standards indicated above are not respected.
  • these connecting means In addition to the choice of a suitable form of the connecting means for laying and interconnecting these elongated elements without the intervention of a person on the ground, these connecting means must be formed and / or attached to the ends of each of the elongated elements of way that there can not be opening of the connection by tearing or deformation of these means. This therefore requires a certain rigidity of the material chosen for producing the elongated elements.
  • the material must be sufficiently elastic to be able to absorb at least partially the kinetic energy developed during an accident, in particular to prevent this energy being entirely supported by the connecting means.
  • this is an important characteristic in that it helps, together with the elasticity of the material of the elongated elements, to prevent the elongated elements being moved excessively during of an accident. Indeed, the longer the elongated elements are moved by the impact of a vehicle, the more kinetic energy developed during this accident must be supported by the connecting means. Beyond an impact threshold which is a function of the adhesion of the elongated elements and their capacity to absorb this kinetic energy, the latter must be supported by the connections between the elements, which entails, where appropriate , breaking some of these links.
  • each elongated element is made of a very heavy material and therefore has a significant adhesion by itself.
  • each of the elongate elements is provided, on the face by which it rests on the ground, means increasing adhesion, such as non-slip pads, made for example of an elastomeric material such as a synthetic rubber.
  • Each of the pads is integral with the elongate member.
  • at least the bearing surface of the pads, by which they are in contact with the roadway, is substantially flat. According to an alternative embodiment, these pads are also provided with crampons.
  • the pads may be positioned approximately one-quarter of the length of the elongate member, measured from either end of the member, or at one end and in the middle of the member. the elongated element. When more pads are used, their arrangement must be adapted to obtain a homogeneous distribution over the entire length of the retaining device formed by the elongate elements assembled.
  • the retaining device according to the invention meets the requirements of the European and French standards indicated above and reaches at least the level of French restraint BT4 and the corresponding European level H1.
  • each elongated member can first work individually before driving the next element in performing its function as a retainer.
  • the female connection means is made in the form of one or more openings made in one of the two end faces of each of the elongated elements and the male connection means is constituted by one or more elements of hooking formed or mounted on the other end face of each of the elongated elements.
  • the precise shapes of the openings and fastening elements are chosen so that these connecting means can engage one another, or separate from each other, only as long as the elongated elements concerned are in the first relative position and the elongated elements concerned are prevented from separate the time they are in the second relative position.
  • the opening and the fastening element are formed so that the fastening element mounted on an end face of an elongated element to be installed can be engaged in the opening made in an end face of an elongated element already laid.
  • the opening will then be wider at the top than at the bottom so that the fastening element can be engaged in the opening when the element to be laid is in the first relative position relative to the element already laid, c that is to say in suspension, but can not leave when the two elongated elements are in the second relative position, that is to say, both posed.
  • the opening must be engaged on the fastening element.
  • the opening will be wider at the bottom than at the top.
  • the recommended number of openings is three, one of which is arranged at a higher level and two are arranged. at a lower level.
  • the number of fastening elements must obviously correspond to that of the openings.
  • the apertures and the corresponding fastening elements must have a shape and dimensions such that, to make a connection between two successive elongated elements, it is necessary to approach a element lengthened by a crane to a element already installed and engage the attachment elements of one in the openings of the other before placing the elongated element on the road.
  • the separation of two elongated elements considered is in the reverse order: a given elongated element is lifted by a crane at least at the end where the separation must be made and is removed from the next element remaining in place to get out the fastening elements of one of the openings of the other elongated element.
