A piering device employs a threaded shaft (10) and a helical bearing plate (20) with a threaded passageway (22) that allows the helical plate (20) to be advanced to any desired location along the shaft (10). The helical plate (20) can also be readily replaced with one or more helical plates of different sizes. The threaded shaft (10) has a key way (14) extending along its length. The threaded passsageway (22) of the helical plate (20) can also be equipped with a key way (24) extending its length. A key (26) is removably inserted into the shaft key way (14) and helical plate key way (24) after these key ways (14, 24) have been rotated into alignment to secure the helical plate (20) at the desired location along the shaft (10).
L'invention concerne un système de pieu comprenant une tige (10) filetée et une plaque (20) d'appui hélicoïdale qui comporte un passage (22) traversant fileté permettant d'avancer le plaque (20) hélicoïdale le long de la tige (10) jusqu'à la position désirée. On peut aussi remplacer facilement cette plaque (20) hélicoïdale par une ou plusieurs plaques hélicoïdales de dimensions différentes. La tige (10) filetée du pieu comporte une rainure (14) de clavette qui s'étend sur la longueur de la tige. Le passage (22) traversant fileté de la plaque (20) hélicoïdale peut également comporter une rainure (24) de clavette s'étendant sur sa longueur. Une clavette (26) amovible peut introduite dans la rainure (14) de la tige et la rainure (24) de la plaque (14) après que ces rainures (14, 24) ont été alignées par rotation, afin de fixer la plaque (20) hélicoïdale à l'emplacement désiré le long de la tige (10).
