FIELD: construction.
SUBSTANCE: device containing an explosive chamber is described, having an opening in its upper base overlapped by an easy-detachable element, the area of the hole can be changed by screwing in replaceable rings, and the easy-detachable element overlaps the opening in the ring above which a protective screen is fixed, wherein the second opening is overlapped by a valve which is pressed against the hole by an electromagnet and is opened by a spring when the contacts are opened, and the force of pressing the valve and compressing the spring is set in such a way that the total force is equal to allowable pressure multiplied by the area of the valve hole. The easy-detachable element contains a metal armoured frame with metal armoured coating and a filler-lead which has four fixed support branch pipes in the ends. Four support rods are rigidly embedded in the cover of the explosive object, which are telescopically inserted into the fixed support branch pipes of the panel, wherein the filler is made in the form of an air-lead dispersed system, the lead is made in the form of crumbs, and the support rods are made elastic, wherein an additional element is attached to the ends of the support rods, to which the support sheets are welded, on the side facing the metal frame with the armoured metal coating, the additional element is made in the form of a box structure, which cavity is filled with elastomer, for example polyurethane, and a vibration cushioning material is used as a material of a box structure, wherein between the additional element and the metal frame with the armoured metal coating, bushings of a rapidly disintegrating material, e.g. triplex-type glass, are installed on the support rods.
EFFECT: increasing the efficiency of protecting buildings, structures, technological equipment against explosions by increasing the speed and reliability of operation with the help of destructible structural elements.
