A screw pile anchor (10) has a tubular shaft (11) with a helical screw flyte (20) and a ground engaging bit (12) at its ground engaging end. The stabilizing assembly (30) has a plurality of fins (34 to 37) radiating from collars (31 to 33) rotatably mounted on the shaft (11). A mounting plate (51) of a lighting column assembly (50) can be attached to the fins (34 to 37) via mounting bolts (40). The stabilizing assembly (30), through the provision of the fins (34 to 37) increases the resistance of the shaft (11) to lateral movement, e.g., under wind loads.
L'invention concerne un dispositif d'ancrage (10) de pilier à vis. Le dispositif comprend un axe tubulaire (11) doté d'une vis (20) et d'un foret (12) qui s'engage dans le sol au niveau de l'extrémité s'engageant dans le sol. L'ensemble stabilisateur (30) comporte une pluralité d'ailerons (34-37) dirigés radialement depuis des colliers (31-33) montés rotatifs sur l'axe (11). La plaque de montage (51) d'un ensemble colonne d'éclairage (50) peut être fixée sur les ailerons (34-37) par des boulons de fixation (40). L'ensemble stabilisateur (30), grâce aux ailerons (34-37), augmente la résistance de l'axe (11) aux déplacements latéraux, par exemple sous la pression du vent.
