PROTECTIVE DEVICE FOR EXPLOSIVE OBJECTS Russian patent published in 2016 - IPC E04B1/92 

FIELD: construction.

SUBSTANCE: invention relates to safety devices used in explosive and radioactive facilities, such as easy detachable panels and roof, blast guards and shields, excessive pressure valves. Safety device for explosive hazardous objects containing metal armored frame armored with metal shell and filler which is made in the form of a disperse system air - lead, wherein the lead is shaped as a crumb, a frame has fixed tube-supports at the ends, and the coating of explosive object has at least three tightly sealed supporting rods with the sheets-stops at the top, which are telescopically inserted in the fixed tubes-supports in metal armored frame, upper part of support rods are fixed with elastically damping elements, one end of which is rigidly connected with its base to sheets-stops, and the other - is free, whereupon each of elastically-damping elements is fixed by screws on its base in the form of a circular disc made of a rigid vibration-damping material such of "Agate" type, on sheets-supports rigidly connected with the rods, and the base of elastically-damping element is connected with the sleeve made of elastomer having a central opening through which the rod passes, said sleeve has at least three openings, coaxial with the rod, in which there are elastic elements, such as coil springs, the upper end of which is connected with the base by means of fastening elements, and the bottom is in non-compressed condition and projects beyond the lower plane of sleeve at a distance determined by force developed by explosive shock wave.

EFFECT: higher reliability of explosion-resistant device operation during emergency explosion at the facility, and ensured return of these device to the original position after explosion.
