Definitions

  • the field of the invention is that of security fasteners for objects fixed to the ground, for example - but not limited to - traffic signs, elements of urban furniture such as fixed or retractable bollards, barrier supports, benches public, planters, shelters, parking meters or vending machines, etc.
  • object will be used to designate elements of this type, the common characteristic of which is that they are fixed to the ground, generally rigidly (which does not exclude that they include removable, retractable, articulated parts, etc.), in particular by sealing in a buried concrete block.
  • safety fastening is meant a fastening - that is to say a means of connecting the object to the buried assembly to which it is connected, for example the solid mass - which is shock-resistant and current stresses but which is liable to give way in the event of a violent impact, the typical case being that of percussion by a vehicle.
  • Such a security attachment is for example described in FR-A-2 621 625, which belongs to the Holder, and which describes an element of urban furniture (a retractable bollard in the ground, in this case), the part of which is located above the ground is fixed by means of screws and thin washers which, in the event of impact, come to deform and pass through holes in a mounting plate located approximately at ground level, the diameter of these holes being slightly less than that of the washers but much greater than that of the screws.
  • the object of this safety attachment is to prevent, in the event of an impact, the part situated below ground level, which includes a complex and costly lifting mechanism, from being damaged as a result of such an impact. .
  • FR-A-2 678 655 filed in France on July 5, 1991 but published only on January 8, 1993, that is to say after the priority date of this patent, and which also belongs to the Holder, also describes a security attachment for an item of street furniture (a barrier support, in particular the species).
  • the support is fixed to the buried solid mass by means of a deformable attachment means which allows the support, in the event of an impact, to lie down and disengage from the base by breaking the fixings.
  • CH-A-631 769 describes an element of the same kind, fixed to the ground by soft metal screws capable of breaking in the event of a violent impact.
  • the configuration of the fixing means does not however make it possible, in the event of an impact, to be certain that the part sealed in the ground will remain perfectly intact; it also does not allow, after a shock, an easy replacement with a minimum of intervention and inexpensive parts.
  • AU-B- 447 473 also describes a support device attached to the ground, comprising interchangeable fracturable elements to separate the object from its support in the event of impact.
  • the mounting device of the invention which is of the general type described by the aforementioned AU-A-447,473 corresponding to the preamble of claim 1, includes the various characteristics set out in the characterizing part of this claim 1.
  • Advantageous embodiments are specified in the subclaims.
  • the invention also relates, considered as such, to an object to be fixed to the ground comprising fixing means having the aforementioned characteristics.
  • Figure 1 illustrates, in perspective, a partial schematic view of the mounting device of the invention, more particularly suitable for mounting a fixed terminal, a post or a pole.
  • FIG. 1 illustrates, in vertical section, the device of Figure 1 and shows the particular means taught by the invention.
  • Figure 3 illustrates the mounting device of the invention of Figures 1 and 2, with the terminal removed and replaced by a closure cap.
  • Figure 4 illustrates the use of a terminal breakout detection switch.
  • FIG. 5 illustrates a detail of embodiment allowing the orientable fixing of a post on the mounting device of the invention.
  • the device illustrated in FIGS. 1 and 2 essentially comprises fixing means, designated by the general reference 1, retained on the ground by a buried assembly 2, for example embedded in a solid mass 3 such as a cylindrical or parallelepiped block in concrete.
  • This buried assembly is connected via an intermediate base 4 to an object 5 such as an item of street furniture, which in the example illustrated is a fixed terminal intended to prohibit the passage of vehicles at a given location.
  • this base 4 is fixed to the terminal 5 by means of screws 6 passed, each through a hole 7a formed in the peripheral part 7b of a disc 7 forming the lower part of the base 4, the central part of this base being a region 7c of greater thickness which will be secured to the buried assembly 2.
  • the screws 6 are either directly screwed into an internal thread 8b of the terminal 5 said, as shown in the right half-section of Figure 2, or screwed into an insert 8a attached to the same terminal, as shown in the left half-section of Figure 2; the first solution is particularly suitable for the case where the terminal is a metallitandis terminal that the second is more suited to the case of a molded concrete bollard.
  • the core 7c of the base 4 has an axial thread 9 which is, in a preferred embodiment, a slightly conical thread (half cone angle of the order of 10 °), with a large pitch thread (8 mm for example) and round profile rather than triangular; we will see below the reasons for this choice.
  • the buried assembly 2 comprises, for its part, a vertical tube 10, for example of steel, carrying a core 11 threaded in the same way as the internal thread 9 of the core 7c of the base 4, so that these two elements can cooperate by screwing.
  • this thread is of a conventional type in the field of assembling drilling tubes, so that it can be produced with a tool that is easy to find, or even use standard parts which are weld on suitable supports.
  • the core 11 is extended peripherally by a disc forming a support plate 12, against which will come to bear the disc-shaped part 7b of the base 4 at the end of screwing.
  • the assembly is completed by sealing rods 13 which, in a manner known per se, will ensure the anchoring of the buried assembly 2 in the concrete 3, facilitating the adjustment of the verticality of the tube 10 and the level of the plate 12 on the concrete of cleanliness 3a (FIG. 2) of the bottom of the excavation before pouring the solid mass, and also imposing a minimum volume on the latter.
  • a flexible seal can be inserted between the plate 12 and the base 4.
  • an electrical contactor microwave switch 14 or an inductive detector, integral with the terminal 5 and whose movable rod rests on the support plate 12 through a hole 15 drilled in the disc 7 of the base.
  • This sensor will make it possible to remotely detect the lifting of the terminal by electrical means known in themselves.
  • the finished ground level can be located in N (Figure 2, half-section on the left), that is to say that the plate 12 will be flush with the ground and the threaded core 11 will slightly emerge from it when terminal 5 is dismantled or torn off.
  • a cable 18 (FIG. 2), preferably made of elastic material with a large elongation at break, connecting the terminal 5 to the tube 10, to avoid any risk of projection. away from the terminal following a percussion of the latter.
  • the element of street furniture must be oriented in vertical axial rotation, for example in the case of a support post, it can be provided that the latter, as illustrated in FIG. 5, has a base in the lower part. 5i extending the upright 5t and pierced with buttonholes 5m receiving the screw rods 6f which will be introduced into tapped holes in the intermediate base 4.
  • the fixing means constituted by the sets of threaded and threaded elements 6 and 8 (8a or 8b), on the one hand, and 9 and 11, on the other hand, each have the particularity of a choice of materials such as one of the two elements (the threaded element or the threaded element) is made of an essentially indestructible material, while the other (the threaded or threaded element, respectively) is made of an essentially destructible material. It may for example be a screw made of an aluminum alloy introduced into a stainless steel thread, or the reverse.
  • an aluminum alloy 7075 in accordance with French standards NFA 50411 and 50451 .
  • This alloy undergoes a T73 heat treatment (quenching, tempering and super- tempering after machining), which provides mechanical characteristics superior to those of mild steel and excellent resistance to intercrystalline corrosion.
  • a ⁇ 10 THR screw, section 48.9 mm made of such an alloy has a tensile strength of 2396 to 2738 daN.
  • an indestructible material for example steel
  • the threaded core 4 is made of an essentially destructible material, for example a cast aluminum alloy.
  • a destructible material such as an aluminum alloy
  • an essentially indestructible material such as stainless steel
  • This structure makes it possible, particularly advantageously, to have two successive action safety devices.
  • the conical shape of the threaded core 11 / threaded core 9 assembly has the advantage of allowing easier escape of the base from the threaded core 11 in the event that this level of security is brought into play. , minimizing the risk of nesting of the thread / tapping assembly due to deformation following the impact.
  • the assembly and disassembly of the terminal is very simple: first of all, the intermediate base is put in place by screwing the screws 6 onto the terminal 5, then the assembly is placed and it is screwed onto the threaded core 11. Given the large pitch of the thread and the taper, one turn to one and a half turns is sufficient to ensure perfect locking, the taper also allowing easy self-centering. Conversely, to dismantle the terminal, we proceed by unscrewing; the fact that none of the fixing elements is apparent, it is necessary for this purpose to have a chain wrench or a carrier clamp to grasp the terminal and drive it in rotation; the use of these specific tools also prohibits an individual not equipped from dismantling the terminal.
  • the support plate 12 of the buried assembly 2 is not necessarily a fixed plate as in the example illustrated, but can also be, in the case of a terminal retractable in the ground, a mobile plate connected to a lifting device, as described in the aforementioned FR-A-2 621 625.
