Patent

CA 2100058

In order to save weight, instead of having hollow sections, a formwork panel (1) has at the edges thereof edge webs (3) which are made of flat material and project at right angles to the forming surface (2), to increase the stiffness the edge webs (3) having between their two aligned longitudinal edges (6,7) serving as a seating for the edge web (3) of a neighbouring formwork panel (1) an area (5) receding towards the centre of the formwork panel (1), there being arranged within said area (5) an oppositely recessed channel or bead (8) open towards the centre of the formwork panel. In this way, an edge web (3) consisting of flat material and of high stiffness ensues, it also being possible for ordinary cramps or clamps (4) to be applied to the bead (8) thereof, without the high weight of hollow sections being necessary. (Fig. 2)
