To protect a construction against terrorist acts, in particular explosive attacks, a protective wall requiring considerable time for destruction is placed in front of it. This protective wall consists of a row of pillars from which are suspended a support net (4) and shielding elements (5) in the form of a box structure, constituting a closed suspended wall (H1), attached by hooks (16) to the net. Each shielding element (5) comprises an armoured front plate (12) and a filling in the form of an inflammable material (13) in which igniting devices (14) are embedded, being triggered under the effect of the firing of the explosives or other means of attack, thus setting fire to the inflammable material (13). The flames and fumes thus produced prevent the terrorists from proceeding further. |
