Abstract

Cette invention concerne un poteau à tête extensible. Une plaque d'extension d'extrémité avant, dont la taille est plus grande que la section transversale de l'extrémité avant du poteau, est installée à l'extrémité avant d'un poteau creux pour en accroître la force d'appui. L’invention concerne plus particulièrement un poteau à tête extensible, dont le trou intérieur ménagé à la surface de la plaque d'extension d'extrémité avant présente une taille optimale plus petite que la cavité du poteau. Selon l'invention, la plaque d'extension d'extrémité avant à trou intérieur critique du poteau à tête extensible présente une taille plus grande que le diamètre de la section transversale de l'extrémité avant d'un poteau creux, ce qui accroît la force d'appui de l'extrémité avant du poteau. La plaque d'extension d'extrémité avant est taillée en forme de bande circulaire munie d'un trou plus petit qu'une cavité du poteau. En particulier, la largeur (tplate) de la plaque d'extension d'extrémité avant se situe au-dessous d'une plage de 40~70% par comparaison avec le rayon (Do) de la plaque d'extension d'extrémité avant.
