Abstract

La présente invention concerne un agencement de support (20) pour un ensemble échafaudage comprenant des montants espacés (12, 14) et des chariots de support de plate-forme, réglables et positionnables le long des montants. L'agencement de support comporte également un cadre de support (21) pour chaque montant, les cadres de support adjacents étant reliés entre eux. Chaque cadre de support comporte deux ou plusieurs pieds espacés entre eux (22, 24) reliés par un élément de struture (28) qui inclut un élément de support montant pour un montant. L'élément de structure et les organes de solidarisation des cadres de support adjacents sont réglables en longueur. Les pieds peuvent également être rendus réglables individuellement pour que l'agencement de support puisse être sensiblement horizontal sur des terrains différents. Chaque pied comporte une embase (23) pivotante en contact avec le sol pour que l'agencement de support puisse être sensiblement vertical sur des terrains différents. L'ensemble échafaudage comporte également un garde-corps. Ce garde-corps comporte des supports de garde-corps en L, espacés, et des organes de fixation pour fixer les supports de garde-corps aux montants respectifs. Les organes de fixation peuvent être réglés de façon à être fixés sur les montants dans différentes positions et reliés aux supports de garde-corps dans différentes positions de sorte que l'agencement de garde-corps convienne aux personnes qui travaillent dans des bâtiments ayant différentes pentes de toit.
