The shuttering structures include bearing 22 and support pieces therefor, arranged on props 1, for supporting floors and troughs of shuttering at construction works. Empty spaces are formed in these structures until the shuttering is produced, through which operatives may accidentally fall. The safety system includes a net stretched out under the shuttering panels, fixed on the actual struts 1 by means of metal fittings 9, 13, 15, 18. The metal fittings 9 are hooks that include at least one screw thread 10 that surrounds the prop 1, with a distant end terminating in the actual hook, for suspending the net. The metal fittings 13 are S-hooks inserted in the orifices 5 of the tube or in the orifices 14 of its upper end plate 4. The metal fittings 15 have the shape of a ring, with two extensions ending in a hook, located at the height of the strut 1, marked by a peg 6 that passes through the orifice 5 in the lower tube of the strut. The metal fittings 18 consist of plates finished at the ends in a hook, with a central orifice 19 for passage of the articulation shaft 21 welded to the support piece 22 on the support thereof. <IMAGE>
