Description

La présente invention a pour objet une structure de liaison d'un mât de lampadaire en aluminium avec une structure d'ancrage.The present invention relates to a connecting structure of a mast aluminum floor lamp with an anchoring structure.

De manière usuelle, les mâts en aluminium tels que ceux utilisés par exemple, mais non limitativement, pour les lampadaires d'éclairage public sont rapportés sur un ensemble de fixation au sol lui-même en aluminium.Usually, aluminum masts such as those used by example, but not limited to, for street lighting street lights are reported on a set of fixing to the ground itself in aluminum.

L'assemblage s'effectue essentiellement par soudure ou collage.The assembly is essentially carried out by welding or gluing.

On connaít par ailleurs une structure de liaison décrite dans le document FR-A-2 641 557 et qui ne nécessite pas de soudure ou collage. Elle est onéreuse et encombrante en raison de la présence d'un manchon épais et écrasable remplissant une fonction d'amortisseur. Un film thermorétractable ne remplirait pas cette fonction.We also know a connection structure described in document FR-A-2 641 557 and which does not require welding or gluing. It is expensive and bulky due to the presence of a thick and crushable sleeve filling a shock absorber function. A heat shrink film would not meet this function.

On a déjà décrit dans le document FR-A-2 535 361 une embase pour poteau de signalisation comportant une semelle se présentant sous la forme d'une bride. Toutefois, cette structure peut présenter des problèmes de tenue au cours du temps.Document FR-A-2 535 361 has already described a base for a pole. signaling device comprising a sole in the form of a flange. However, this structure can present problems of resistance over time.

La présente invention se propose de remédier aux inconvénients de l'art antérieur en proposant une structure de liaison qui évite toute soudure ou collage sans poser de problème dimensionnel.The present invention proposes to remedy the drawbacks of the art by proposing a connection structure which avoids any welding or sticking without posing any dimensional problem.

Conformément à l'invention, ce résultat est obtenu avec une structure de liaison d'un mât de lampadaire en aluminium au sol constituée par une semelle ayant une partie en forme de bride destinée à enserrer mécaniquement la base du mât, caractérisée en ce que la semelle est en fonte GS et que la structure de liaison comporte également une manchette thermorétractable destinée à être interposée entre la bride et le mât sur la totalité de leur zone de contact réciproque.In accordance with the invention, this result is obtained with a structure of connection of an aluminum lamppost mast to the ground constituted by a sole having a flange-shaped part intended to mechanically grip the base of the mast, characterized in that the sole is made of GS cast iron and that the connection structure also includes a heat-shrinkable sleeve intended to be interposed between the flange and the mast over their entire reciprocal contact area.

La manchette thermorétractable conforme à l'invention réalise une isolation électrique dans la zone de contact et on parvient en fait à un potentiel voisin du zéro.The heat-shrinkable sleeve in accordance with the invention provides insulation electric in the contact area and we actually reach a potential close to zero.

Pour renforcer cet effet, la semelle pourra éventuellement être elle-même galvanisée. To reinforce this effect, the sole could possibly be itself galvanized.

On comprendra mieux l'invention à l'aide de la description faite ci-après d'un mode de mise en oeuvre donné à titre d'exemple non limitatif en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en élévation en coupe au niveau d'une structure de liaison conforme à l'invention,
  • la figure 2 est une vue de dessus d'une semelle utilisée dans la structure de liaison conforme à l'invention.
The invention will be better understood using the description given below of an embodiment given by way of nonlimiting example with reference to the appended drawings in which:
  • FIG. 1 is a sectional elevation view at the level of a connecting structure according to the invention,
  • Figure 2 is a top view of a sole used in the connecting structure according to the invention.

Le problème à résoudre consiste à fixer un mât en aluminium (1) dont seule la partie basse est représentée sur une semelle (2), formant socle.The problem to be solved consists in fixing an aluminum mast (1) of which only the lower part is shown on a sole (2), forming a base.

Conformément à l'invention, on interpose dans la zone de contact une manchette thermorétractable (3) en matériau synthétique.According to the invention, a contact is interposed in the contact zone heat-shrinkable cuff (3) of synthetic material.

La manchette est installée sur la base du poteau après dégraissage et préchauffage de la zone concernée.The cuff is installed on the base of the post after degreasing and preheating of the affected area.

On se réfère à la figure 2. La semelle (2) se présente sous la forme d'une bride ouverte (4). Le maintien du mât est obtenu par serrage de vis (5,6), représentées à la figure 1, qui rapprochent les deux mâchoires de la bride (4).We refer to Figure 2. The sole (2) is in the form of a open flange (4). Maintaining the mast is obtained by tightening screws (5,6), shown in Figure 1, which bring the two jaws of the flange (4).

La semelle est munie de haricots (7) qui servent à l'ancrage dans le sol, par coopération avec des tiges de scellement.The sole is provided with beans (7) which are used for anchoring in the ground, by cooperation with sealing rods.

Claims (3)

  1. Structure for connecting a lamp post formed from aluminium to the ground, comprising a footing having one portion in the form of a clamp (4) intended to grip the base of the post mechanically, characterised in that the footing (2) is formed from GS cast iron, and in that the connecting structure also comprises a heat-retractable sleeve (3) intended to be interposed between the clamp (4) and the post (1) over the entirety of their mutual area of contact.
  2. Connecting structure according to claim 1, characterised in that the clamp is an open clamp (4), co-operating with clamping screws (5, 6).
  3. Connecting structure according to one of claims 1 to 2, characterised in that the footing is galvanised.
