Abstract

L'invention concerne un poteau destiné à être utilisé comme élément de support d'un coffrage horizontal ou comme élément de soutien ou d'étayage. Les moyens de renforcement entre les poteaux présentent une structure tubulaire (4) comportant des tubes horizontaux (7) et des entretoises (8), aux extrémités des tubes horizontaux (7) étant associées des pinces de renforcement (9) qui embrassent les tubes extérieurs (1) des poteaux, une tour d'étaiement s'adaptant auxdits poteaux. Les pinces de renforcement (9) comprennent une pince fixe (1) soudée à l'extrémité du tube horizontal (7) et celle-ci présente un creux (12) dans lequel vient se placer une nervure axiale (13) du tube extérieur (1) pour le maintenir, entourant le tube extérieur (1) du poteau à l'aide d'une pince mobile (14) pivotant autour de la pince fixe (11), une cale (16) complémentaire fixe la pince mobile (14) à la pince fixe (11) dans cette position.
