Working platforms for scaffolding must be light and functional and easily stackable. It must therefore be possible to include all their components with a long useful life in the static calculation as well. The requirements include both great regidity in the corner joint of a rectangular bearing frame for the working platform and the smallest possible gaps between adjacent platforms. Above all, however, the smallest possible number of components must keep the costs of such a working platform within limits. To this end the invention makes use of a U-shaped folded footplate (2) clamped between the longitudinal bearers (11) of the bearing frame. If, in addition, at least the longitudinal bearers (11) are rectangular hollow sections, no dirt or residual building material can enter the working platform.

Les plateformes de travail destinées aux échafaudages doivent être légères et fiables, tout en étant facilement empilables. Tous leurs composants présentant une longue durée de vie doivent donc pouvoir être inclus dans les calculs statiques. Une rigidité élevée des joints de coin d'un cadre porteur rectangulaire destiné à une plateforme de travail, et un espace le plus réduit possible entre deux plateformes de travail adjacentes, constituent des exigences d'égale importance. Cependant, il importe avant tout de limiter le coût de ce type de plateforme de travail en utilisant le moins possible de composants. L'invention utilise à cet effet, outre un cadre porteur, une passerelle de tôle repliée en U (2) qui est fixée entre les longerons (11) du cadre porteur. Si au moins les longerons (11) se présentent sous forme de profilés creux rectangulaires, aucune impureté ni reste de matériau de construction ne risque de se déposer à l'intérieur de la plateforme de travail.
