Supporting element for scaffolds

Abstract

A supporting element for scaffolds includes a lower supporting plane or plate suited to be rested on the ground; ribs distributed on top of the lower plane or plate, integral with the lower plane or plate and all having their upper edge lying on the same plane, suited to constitute bearing elements for the bearing base of the scaffold and stiffening elements for the supporting element; a quadrilateral projection or wall, placed on top and generically at the center of the lower plane or plate, whose sides are higher than the ribs, suited to delimit the position where the bearing base of the scaffold rests on the ribs and to prevent the bearing base from slipping on the upper edges of the ribs; and a perimeter wall above the lower plane or plate, parallel to the upper ribs and delimiting the upper ribs.
