Fabrication et la pose des escaliers préfabriqués


Recommended Posts

Salut à tous,


j'aurais voulu savoir si un texte français ou européen a remplacé le dtu 21.3 (retiré en 2000) concernant la fabrication et la pose des escaliers préfabriqués.


Ma problématique se situe surtout sur les conditions d'appuis lors de la mise en place de "becquets préfa.".


Merci .
