[i][color=#374953][size=3]bonjour à tous, [/size][/color][/i]
[i][color=#374953][size=3]Pourriez vous me conseiller, est ce que je peux utiliser des poutres UPN 80 (image ci-joint) pour construire un petit palier ( 75cm x 90cm) au dessus d'une cage d'escalier. Ce palier est destiné pour supporter un escalier en bois sans contremarche (largeur 60 cm) qui mènera au grenier. Je pensais installer 3 poutres UPN 80 posées au sol sur le coté 80mm (bras vers le haut). Les extrémités des poutres ( au moins 40 cm)seront posées au sol dans les pièces adjacentes . je les fixerais au sol par scellement chimique. Je sais qu'il existe des poutres IPE 80. Je crains qu'en les choisissant je n'aurai pas assez de largeur sur les ailes pour pouvoir les percer pour faire mon scellement chimique.[/size][/color][/i]
