Description

The present invention relates to a device for grounding a plate

  intended to support various objects, such as signs, street lights, or more constraining structures to seal because of their size and / or weight, such as a

  mast for candelabra, an electric pole or a large billboard.

  Ground anchoring of such objects generally requires civil engineering work, such as digging into the ground and pouring concrete, thus making this operation relatively complex and expensive.

  In order to respond to this technical problem, patent FR 2 829 777 proposes a high-load resistant anchoring means consisting of a mounting plate comprising a plurality of anchoring points, each of these points being formed by the assembly of a stud made of resistant material and a peg with deployable anchoring rods. Such stakes are described in patent EP 0677630.

  Nevertheless, the establishment of such an anchoring device has some disadvantages.

  First, this mode of implementation requires digging the ground, in order to position the anchoring studs under the mounting plate of the object, before the insertion of the stakes.

  In addition, it requires a special effort on the part of the user to align the conduits of the anchor pads located under the plate, with the holes of the mounting plate for the insertion of the anchoring stakes.

  Finally, such a device is not modular, insofar as the elements ensuring the attachment of the stake to the plate - that is to say the retaining piece inside the conduit of each stud and the pads themselves - are specific to each stake diameter used.

  The object of the present invention is therefore to provide a ground anchoring means for a support plate of objects, this means being modular, simple to implement, avoiding any civil engineering work, while remaining perfectly resistant to heavy loads and inexpensive to manufacture.

  According to the invention, this object is achieved by means of a device comprising: a metal mounting plate of said object comprising a receiving zone of this object and at least two openings, at least two metal anchoring stakes of diameter equal to or slightly less than that of the openings of the plate intended to be engaged in these openings and to be secured to the plate, characterized in that the head of each post is equipped with a plate, perpendicular to the body of the stake, intended to bear on the plate, means being provided to achieve the fixing of the plate on the plate.

  From a practical point of view, anchoring the plate to the ground is carried out according to the following steps.

  First, it is placed on the floor where the object is to be sealed. The stakes are then engaged through the openings of the plate and hammered into the ground, until the plate of each stake comes into contact with the plate. Finally, the fixing of the plate on the plate ensures the securing of the stakes and the plate.

  Advantageously, the support plate is preferably made of a metal capable of withstanding significant loads, without undergoing deformation.

  According to another characteristic of the invention, the fixing of each fixed plate of a post is made by screwing into threaded holes 20 formed in the plate.

  According to another characteristic of the invention, each plate has holes for the passage of fixing screws on the plate.

  In relation to the two preceding features, the fixing of the plate on the support plate is ensured by engaging a fixing screw through the holes of the plate and the plate, the holes of the plate being pre-aligned with those of the plate. Such a method of attachment has the advantage of being easy to implement. Indeed, it does not require any civil engineering operation, such as excavations and / or concrete pours.

  According to another characteristic of the invention, the fastening of each fixed plate of a stake is carried out by means of a metal cap which, intended to cover and to lock the plate on the plate, is fixed by screwing to that -this.

  This anchoring device has a modular character, insofar as the same cap, of standard size, can be used to hold the plate of anchoring stakes having different diameters, unlike the patent FR 2 829 777 which presented parts of retaining located inside the duct of the anchor pad, these parts being specific to each tube of well-defined diameter. For example, the same cap may be suitable for the following stakes diameters: 21, 27, 33 cm.

  According to another characteristic of the invention, said metal cap comprises: - a central recess zone intended to house the plate of the anchoring post, and - a peripheral part, in which are formed at least two holes allowing the passage of the screws fixing on the plate.

  Advantageously, the recess area of the cap is of standard size, so as to receive different diameters of platinum, hence the modular nature of this type of attachment.

  According to another characteristic of the invention, the anchoring stakes 15 are tubular and contain deployable anchoring rods.

  Such pegs, known from patent FR 2 829 777, use deployable son, released at the end of each pole after planting, to strengthen the anchoring of the stakes in the ground. Advantageously, the use of deployable son avoids destructuring the ground, as occurs with anchors fin or pins.

  According to another characteristic of the invention, the mounting plate comprises, around each of said openings, at least two holes each for receiving a screw, intended to ensure the fixing of the shell on said plate.

  For a good understanding, the invention is again described below with reference to the attached schematic drawing showing, by way of non-limiting example, several embodiments of the anchoring device it relates.

  Figure 1 is a perspective view of the various elements that make up a first device.
