Abstract

Un échafaudage pliable pour bâtiments est destiné à être utilisé sur un toit à deux pans inclinés et permet ainsi d'éliminer le recours à un échafaudage complexe dressé autour d'un corps de cheminée devant être réparé. Une unité d'échafaudage comprend un élément de base (1), un montant (12) et une bride coulissante (8) reliant de façon pivotante une des extrémités du montant (12) à la base (1). Une attache (15) relie la base (1) et le montant (12). L'une et l'autre extrémités de l'attache (15) sont reliées de façon pivotante respectivement à la base (1) et au montant (12). L'unité d'échafaudage peut passer d'une position repliée, dans laquelle la base (1), l'attache (15) et le montant (12) sont sensiblement parallèles, à une configuration dépliée, dans laquelle la base (1) descend le long de la pente du toit et l'attache (15) est en position sensiblement horizontale.
