<p>The invention relates to a structure including: an upper bracket provided with the supporting element for the wall formwork panels, a main working platform and a protective railing; and a lower bracket provided with a passage platform and arms joining same to the upper bracket. The invention is characterised in that the lower bracket is formed by at least one rigid module or section associated with the platform of the upper bracket and one or more successive modules or sections pivoted to one another, with vertical arms adjacent to the wall and opposite same in order to form substantially parallelepiped cage structures having a height that is limited to a pre-determined value in order to prevent the risk of falls.</p> |
